Definitions

  • This invention has for its objectv anew protecting device against-X-rays and similar radiations adapted to be used in the manufacture of protecting screens, plates or shields, concaveV discs or cups and generally speaking all articles employed in radiography.
  • Said device comprises an improved supporting structure and a composition opaque to X-rays and like radiations, containing lead, bismuth and like salts, to which an adhesive substance may be added in such manner as to obtain an homogeneous mass which hardens on drying.
  • the cohesion of said mass may be increased by com resson.
  • opaque composition is prefera ly reinforced by combining it with an inner structure made of fabrics, libres, felting muslin, tarlatan and the like.
  • the desired varticles are thus ormedoi' several layers' successively disposed upon a form or mandrel and alternately of the mixture and of bands of tarlatan, silk or other light fabric crossing each other so as to increase the solidity and avoid deformations.
  • the active salts mixed with the adhesive substance are thus enclosed on the one hand between the successive layers of fabric and on the other hand inside the body of said fabric, in the meshes thereof.
  • the opaque composition can also be disposed between two outer walls in one er several parts, made of wood or any other insulating substance such as rubber, libre, etc. T the mixture is not reinforced it may der instance be cast with addition of plaster cr not, said mixture being compressed or not between the aforesaid outer walls.
  • Similar walls may also be used in addition 'to the outer walls to form one or several internal structures in the body of the mass made of the mixture of salts and adhesive substance, and strengthening fabric may also be employed in addition therewith.
  • the fibres are preferably disposed in crossing directions.
  • the outer walls may be cast or moulded if they are made of a substance'permitting such an opera-l tion. lt is obvious that instead or" tarlatan any elted substance or veneer may be used the diierent parts of material being perforated and glued together in 'such manner as to provide free spaces or apertures containing opaque mixture or saltsonly.
  • the said walls may each other.
  • Fig. l is a diagrammatical cross section of a plate or shield according to the presentinventlon.
  • Figs. 2 and 3 are similar views of two modified forms of construction.
  • the shield or protecting plate comprises a body a formed of a mixture of opaque salts such as lead or bismuth salts.
  • Bands of tarlatan, musln or a similar open work fabric are embedded in vsaid mixture as shown at to act as reinforcing means and'outer walls c formed of veneer are provided.
  • the bands of fabric may be replaced by sheets b2 of veneer, felt, cloth, ebonite, bre, rubber or similar material Aprovided with suitable apertures b1 which are filled in by the opaque mixture.
  • the body of the opaque article may be formed of veneer, telt, cloth or other sheets d' which are cemented one upon the other and are provided with openings f, the latter being lilled with the above described opaque mixture, said openings being out orn alignment in the successive layers so that an ecient protection is assured on the whole surface of the panel or similar protecting device.
  • a protecting device which is opaque to Xerays and to radiations from radio-active substances comprising in combination solid outer walls of insulating material and an opaque medium between said outer walls.
  • a protecting device which is opaque to X-rays and to radiations from radio-active substances containing in combination opaque substances, adhesive substances forming an homogeneous mixture and outer reinforcing walls of insulating substance.
  • a protecting device which is opaque to X-rays and to radiations from radio-active substances containing in combination opaque substances, adhesive substances forming an homogeneous mixture, outer reinforcing walls of insulating material and reinforcing walls incorporated in said mixture.
  • a protecting device which is opaque to X-rays and to radiations from radio-active substances containing in combination opaque substances, adhesive substances forming an homogeneous mixture, insulating walls in said mixture and free spaces or apertures in said walls, filled with one of said series ofsubstances or with the mixture thereof.
  • a protecting device which is opaque to X-rays and to radiations from radio-active substances formed of insulating sheets cemented one u on the other and provided with openings lled with a mixture of opaque substances and adhesive substances, said openings being out of alignment in the successive sheets.
