A matrix for use in the production of rubber or metal relief printing plates is made by producing a block of friable material, as by casting a mixture of plaster of Paris and water on plate glass and drying, applying a sealing coat as of a mixture of starch or wax emulsion with glycerin to the surface of the block which has been in contact with the plate glass, applying a coat of asphalt or mixed asphalt and gilsonite to the sealing coat, applying a layer of rubber latex containing a light-sensitive material such as bichromated glue and gelatin, exposing to light under a transparency, washing to remove unhardened parts of such layer, sandblasting to remove the asphalt, the sealing coat and a portion of the block from places unprotected by the hardened parts of the light-sensitive layer, and removing remaining parts of the latter, the asphalt and the sealing coat as by solvent. In casting printing plates from the matrix, suction may be applied to the reverse side thereof. The block of friable material with sealing coat, asphalt coat, and light-sensitive rubber latex layer is included in the terms of the claims.

Abstract: 1531542 Semi-conductor devices RCA CORPORATION 19 Feb 1976 [26 Feb 1975] 06577/76 Heading H1K A semi-conductor device comprises two doped regions 16 and 56 having a layer of solder 32 in contact with both regions, and a terminal lead 36 which is in spaced relation with layer 32 and connected to the region 16. As shown, the terminal lead 36, connected to both N-type region 56 and P-type region 16 by a solder layer 40, is connected to layer 32 through regions 16 and 56. The conductivity of region 56 may be higher than that of region 16. Also, the length of layer 40, in the direction of current flow between lead 36 and region 16, may be small in comparison with the length of layer 32 to substantially reduce any resistance increase due to the soldered connection between lead 36 and the layer 40.

Abstract: 787,192. Fluid-actuated valves. HYMATIC ENGINEERING CO., Ltd. Feb. 16, 1956 [March 7, 1955], No. 6589/55. Class 135. A combined pressure regulator and relief valve comprises a cylinder closed at its ends containing a sealed flexible longitudinally extensible bellows i containing a compressible fluid and constituting a pressure sensitive element controlling the valve e at one end admitting high-pressure gas from c to the cylinder from which gas at lower pressure is delivered at d, and controlling a relief valve k at its other end which allows gas to escape from the cylinder when a predetermined pressure is exceeded, means v being provided for controlling the pressure at which the relief valve opens and for indicating the output pressure from the regulator. Downward movement of the hand screw v compresses the bellows against its loading spring j and sets a higher outlet pressure which is indicated by a pointer moved by the collar z. Should outlet pressure rise unduly the bottom plate h of the bellows is moved upwardly to abut a cylinder shoulder m and moves a bellows probe g away from the valve e so that it closes and further rise in outlet pressure then compresses the bellows and opens the relief valve k. The pressure differential between the set pressure and the relief pressure may be adjusted by moving the valve e axially relatively to the probe g by turning the screw 4 housing the complete inlet valve.

Abstract: 1383393 Biphenylyloxy benzoyl compounds RAYCHEM CORP 15 Feb 1972 [16 Feb 1971 17 Jan 1972] 6947/72 Heading C2C [Also in Division C3] The invention comprises compounds of general formula wherein R represents a hydroxy group, an alkoxy group containing from one to three C atoms or a halogen. The 4-(4-biphenylyloxy) benzoic acid monomer is preferably obtained by Ullmann condensation of p-hydroxybiphenyl and p-chlorotoluene to yield 4-(4<SP>1</SP>-biphenylylo x y) toluene, which is in turn subjected to cobalt acetate-catalyzed oxidation to form the product. Treatment of 4-(41-biphenylyloxy)benzoic acid with thionyl chloride yields the corresponding acid chloride, which in turn may be converted to the acid fluoride by reaction with anhydrous hydrogen fluoride. The acid ester monomers are obtained at reflux temperature by reaction of the corresponding acid chloride with the appropriate alcohol in the presence of triethylamine, or alternatively by sulphuric acid-catalyzed reaction of the alcohol and 4-(4<SP>1</SP>-biphenylyloxy) benzoic acid at reflux. The corresponding 3<SP>1</SP> and 2<SP>1</SP> monomers are similarly obtained starting from commercially available 3-hydroxybiphenyl and 2-hydroxybiphenyl respectively.

Title: Improvements in or relating to the removal of hydrogen cyanide from gas or aqueous solutions
IPC: B01D47/06
Filed: 1959-03-03
Abstract: <PICT:0897543/III/1> Hydrogen cyanide is removed from a gaseous mixture by water washing and the solution is aerated with air and carbon dioxide to p  remove the hydrogen cyanide.  In particular washing water from a gas washer used to wash dust and hydrogen cyanide from blast furnace gases is treated.  The air contains at least 0,25% carbon di-oxide and the air containing carbon di-oxide may be a mixture of air and flue gases.  The treatment may be effected in a number of stages and last-traces of hydrogen cyanide may be removed by ozonization.  In Fig. 1 raw blast furnace gas enters a washer 11 at A and is sprayed with water in the lower section of the washer and passes over wetted packing media in the upper section.  The washed gas is further washed in a rotary spray washer 12 with fresh water and the cleaned gas passes out through a moisture eliminator 14 to the outlet B.  Washing water containing hydrogen cyanide and dust particles from both washers and the moisture eliminator 14 passes to a settling and separator tank.  A slurry is pumped off from the base of the tank and water containing hydrogen cyanide is taken off by the pipe 29 and fed to a tank 27. Water in the tank 27 is partly returned to the washer 11 and partly fed by line 32, tank 31, line 33 and pump 37 to sprays 44 in a gas-liquid contact tower 41.  A large volume of air is drawn through the tower through air inlet grille 47 by a fan 99 and flue gases are admitted at 48. Air, flue gases and hydrogen cyanide escape to atmosphere.  The thus treated water is if necessary treated in further similar towers until the desired removal of hydrogen cyanide is obtained. As described four towers similar to 41 are provided, each being traversed in turn by the water being treated.  An arrangement of valves and by-passes enables any particular tower to be taken out of service while keeping the remaining towers in operation.
