  <B>Brevet</B>     addition el    subordonné au brevet principal n  178328.    Installation pour l'utilisation d'un gaz     eombustible    liquéfié.    L'objet de l'invention est une installation  pour l'utilisation d'un gaz combustible liquéfié.  



  Elle comporte, comme l'installation selon  la revendication     II    du brevet principal, des  moyens pour détendre le gaz liquéfié en utili  sant une partie de l'énergie qui a été emma  gasinée en lui lors de sa liquéfaction et au  moins un dispositif dans lequel il brûle en  suite en libérant sous forme calorifique une  partie au moins de l'énergie qu'il contient  de par sa nature.

   Elle est, de plus, carac  térisée par<B>lé</B> fait que les moyens pour dé  tendre le gaz liquéfié comportent une enceinte       oir    du froid est produit et qui est alimentée  en gaz liquéfié à l'état liquide par l'inter  médiaire d'un dispositif assurant un niveau  constant du liquide dans cette enceinte, d'où  le produit gazeux provenant de l'évaporation  du liquide se rend, au travers d'un dispositif  qui en abaisse la pression à une valeur donnée,  au dispositif dans lequel il brûle.  



  La figure unique du dessin annexé re  présente schématiquement, en coupe verticale,    une forme d'exécution de l'installation selon  l'invention, donnée à titre d'exemple.  



  Cette forme d'exécution présente un appa  reil frigorifique a comportant une chambre  froide b où règne une température relative  ment basse et qui est fermée par une porte     bi.     Dans la partie supérieure de la chambre b  se trouve une seconde chambre 20 où règne  une température beaucoup plus basse et qui  sert à la production de glace en     mouleaux     par exemple; elle est fermée par une porte 21  et est entourée d'une enceinte 22.  



  Dans l'enceinte 22 débouche un tuyau     h     amenant un gaz combustible liquéfié d'une  bonbonne f,     c'ëst-à-dire    d'un récipient     trans-          portable        oii    le gaz liquéfié est logé en vue  de son utilisation eu dehors du lieu de pro  duction. Afin que le tuyau h amène dans  l'enceinte 22 du gaz à l'état liquide, il est  relié à un tuyau plongeur 23 partant de la  partie inférieure de la bonbonne f ; un ro  binet k commande à volonté l'arrivée du gaz  à l'état liquide dans l'enceinte 22.

   Cette      arrivée est en outre commandée automatique  ment par un pointeau 30 servant â clore  l'orifice 32 du tuyau h et actionné par un  flotteur 31 porté par le gaz liquéfié se trou  vant à l'état liquide dans l'enceinte 22.  



  Du haut de l'enceinte 22 part un tuyau g  aboutissant à un brûleur i commandé par un  robinet<I>j.</I> Dans le tuyau<I>g</I> est intercalé un  dispositif servant à abaisser la pression du  produit gazeux sortant de 22 à la     valeur     .convenable pour la combustion dans i: 1,020  à 1,030 kg absolu par exemple. Ce dispositif  peut se trouver soit en<B>33.,</B> à l'intérieur de  la chambre b, de sorte qu'il subit l'influence       thermique    de l'enceinte 22, soit en 33b à  l'extérieur de la chambre b, si bien qu'il est  isolé     thermiquement    de l'enceinte 22, dont  il ne subit pas l'influence.  



  Le fonctionnement de la forme d'exé  cution décrite est le suivant:  Supposons que la bonbonne f contienne  un gaz combustible liquéfié appartenant au  groupe des hydrocarbures acycliques de la  série des paraffines, dont la formule générale  est     C H2 +2,    du propane par exemple, dont  la formule est     C3Hs    et qui a sous forme  commerciale une tension absolue de vapeur  de 7,8 kg à 15   C. Si l'on ouvre le robinet     k,     la tension .de vapeur existant au haut de la  bonbonne f chasse du gaz liquéfié à l'état  liquide dans l'enceinte 22. Le gaz liquéfié  s'y évapore en prenant la chaleur voulue  aux chambres 20 et b qu'il refroidit ainsi.

    De là, le produit gazeux passe dans le tuyau g,  traverse le dispositif     33.    ou     33t"    où il est  amené sous la pression convenable au     brûleuri.     Le pointeau 30 règle l'arrivée du gaz à l'état  liquide dans l'enceinte 22 suivant les besoins,  de manière à y maintenir un niveau constant.  



  Dans ces conditions, l'énergie     qui    a été  emmagasinée par compression dans le propane,  lors de sa liquéfaction, est partiellement ré  cupérée sous forme de froid, dans les chambres  20 et b, alors qu'elle serait perdue sans cela,  puisque la pression du gaz doit dans tous  les cas être ramenée à la faible pression  nécessaire- 1,020 à     1.,030    kg absolu par  exemple, nécessaire à l'alimentation du brû-    leur     i.;    quant à l'énergie qu'il contient na  turellement, elle est libérée en tout ou en  partie dans le brûleur i sous forme d'énergie  calorifique.  



  Du fait que le gaz liquéfié arrive à l'état  liquide dans l'enceinte 22, aucune évaporation  et aucune détente prématurées n'ont lieu dans  le tuyau     h.:    toute l'opération et toute la dé  tente se passent dans 22, d'où plus grande  absorption de chaleur par celle-ci et abaisse  ment plus grand de la température en 20  tout d'abord, en b ensuite. L'état liquide du  gaz liquéfié dans cette enceinte permet aussi  de régler son arrivée par la commande d'un  simple flotteur.  



  Il- peut naturellement y avoir plus d'un  brûleur i.  



  La chambre b peut être munie d'un re  vêtement calorifuge.  



  D'autres gaz du groupe mentionné peuvent  encore être utilisés, par exemple le butane  et     l'isobutane,    04H1 , le butane commercial  ayant une pression absolue de 2,62 kg à  <B>150</B> C, un mélange de deux ou trois de ces  trois gaz. On peut également se servir de gaz  n'appartenant pas à ce groupe et ayant les  propriétés voulues.  



  Il a été indiqué plus haut que le gaz  utilisé est logé dans un récipient transpor  table, la bonbonne f, dans lequel il a été  logé sous forme liquide à l'usine de produc  tion ou à une station intermédiaire et qui  permet de s'en servir en un autre lieu. On  peut aussi envisager le cas où le gaz est  utilisé au lieu même de sa production pour  donner naissance à du froid, à de l'énergie  calorifique, et éventuellement encore à de  l'énergie mécanique.



  <B> Patent </B> addition and subordinate to main patent n 178328. Installation for the use of liquefied fuel gas. The object of the invention is an installation for the use of a liquefied fuel gas.



  It comprises, like the installation according to claim II of the main patent, means for expanding the liquefied gas by using part of the energy which has been stored in it during its liquefaction and at least one device in which it then burns by releasing in calorific form at least part of the energy it contains by its nature.

   It is, moreover, charac terized by <B> the </B> fact that the means for expanding the liquefied gas comprise a chamber where cold is produced and which is supplied with liquefied gas in the liquid state by the intermediary of a device ensuring a constant level of the liquid in this chamber, from where the gaseous product from the evaporation of the liquid goes, through a device which lowers the pressure to a given value, to the device in which it burns.



  The single figure of the appended drawing shows schematically, in vertical section, an embodiment of the installation according to the invention, given by way of example.



  This embodiment has a refrigeration appliance a comprising a cold room b where a relatively low temperature prevails and which is closed by a door bi. In the upper part of the chamber b is a second chamber 20 where a much lower temperature prevails and which is used for the production of ice cream in molds for example; it is closed by a door 21 and is surrounded by an enclosure 22.



  Into the enclosure 22 opens a pipe h bringing a liquefied combustible gas from a carboy f, that is to say from a transportable receptacle where the liquefied gas is housed for use outside the place of production. So that the pipe h brings gas in the liquid state into the chamber 22, it is connected to a dip pipe 23 starting from the lower part of the cylinder f; a valve k controls the arrival of gas in the liquid state in the enclosure 22 at will.

   This arrival is also controlled automatically by a needle 30 serving to close the orifice 32 of the pipe h and actuated by a float 31 carried by the liquefied gas in the liquid state in the enclosure 22.



  From the top of the enclosure 22 leaves a pipe g leading to a burner i controlled by a valve <I> j. </I> In the pipe <I> g </I> is interposed a device serving to lower the pressure of the gaseous product leaving 22 to the value suitable for combustion in i: 1.020 to 1.030 kg absolute for example. This device can be either in <B> 33., </B> inside the chamber b, so that it is subjected to the thermal influence of the enclosure 22, or in 33b outside of the chamber. chamber b, so that it is thermally insulated from enclosure 22, which it is not influenced by.



  The operation of the execution form described is as follows: Suppose that the cylinder f contains a liquefied fuel gas belonging to the group of acyclic hydrocarbons of the paraffin series, the general formula of which is C H2 +2, for example propane , whose formula is C3Hs and which has in commercial form an absolute vapor pressure of 7.8 kg at 15 C. If the valve k is opened, the vapor pressure existing at the top of the cylinder f drives off gas liquefied in the liquid state in the enclosure 22. The liquefied gas evaporates there, taking the desired heat from the chambers 20 and b which it thus cools.

    From there, the gaseous product passes into the pipe g, passes through the device 33. or 33t "where it is brought under the suitable pressure to the burner. The needle 30 regulates the arrival of the gas in the liquid state in the chamber 22. as needed, so as to maintain a constant level.



  Under these conditions, the energy which was stored by compression in the propane, during its liquefaction, is partially recovered in the form of cold, in the chambers 20 and b, whereas it would be lost otherwise, since the pressure gas must in all cases be brought to the low pressure necessary - 1.020 to 1..030 kg absolute, for example, necessary to supply the burner i .; as for the energy which it naturally contains, it is released in whole or in part in the burner i in the form of heat energy.



  Because the liquefied gas arrives in the liquid state in enclosure 22, no premature evaporation and expansion takes place in pipe h .: the entire operation and all the de-tent take place in 22, d ' where greater absorption of heat by it and greater lowering of the temperature in 20 first, then in b. The liquid state of the liquefied gas in this chamber also makes it possible to adjust its arrival by controlling a simple float.



  There may of course be more than one burner i.



  Room b can be fitted with a heat-insulating jacket.



  Other gases of the group mentioned can still be used, for example butane and isobutane, 04H1, commercial butane having an absolute pressure of 2.62 kg at <B> 150 </B> C, a mixture of two or three of these three gases. It is also possible to use gases which do not belong to this group and which have the desired properties.



  It was indicated above that the gas used is housed in a transportable receptacle, the cylinder f, in which it has been housed in liquid form at the production plant or at an intermediate station and which allows it to be stored. serve in another location. It is also possible to envisage the case where the gas is used at the very place of its production to give rise to cold, to calorific energy, and possibly also to mechanical energy.
