Title: Improvements in or relating to metal mesh screens for example for use in cathode ray tubes
IPC: C25D1/08
Filed: 1935-05-23
Abstract: 458,736. Making mesh screens; electrodeposition. HOLMAN, H. E., 4, Fairway Avenue, Garden City, Yiewsley, Middlesex. May 23, 1935, No. 17164/36. Divided out of 458,675, [Group IX]. [Class 83 (ii)] [See also Groups XXXVI and XL] A metal mesh screen for use in an electron discharge device is formed by a process including the steps of forming an electrically-conducting matrix 30 having ribs 30a corresponding to the finished screen, applying a layer 31 of an insulating material such as an asphalt varnish, removing the layer 31 until the tops of the ribs appear, and then lapping until the exposed copper surface corresponds to the desired form of the screen, depositing a gold or other metal layer on the tops 30a of the ribs and then removing the remainder of the insulating medium and the matrix 30 to leave a screen 32, a supporting member being attached to the screen before complete removal of the matrix. The deposit may be applied to two plates placed back-to-back and soldered at their edges. An asphalt coating is removed by boiling in ether. A screen may be secured to a nickel frame by methods described in Specification 458,675. Alternatively, a screen 32, Fig. 13, is secured to a mosaic screen for cathode-ray tubes such as used in the electrical transmission of pictures and comprising crossed wires 35b each insulated by a glass tube 36 and having gold cups 38 in the interstices, the screen 32 acting as a potential stabilizer and preventing the spreading of secondary electrons. In the production of the composite screen, the matrix 30 and deposited screen 32, have a film of nickel deposited thereon and then a thick deposit of silver 34, the copper matrix being removed by dissolving in acid, electrolytically, or by ammonium persulphate as described in Specification 458,675. The matrix so formed is employed with a matrix 37 in a process similar to that described in Specifications 447,824, [Group XL], and 455,233 whereby the crossed insulated wires 35b are subjected to heat and pressure, causing adhesion of the glass tubes 36 at the junctions and applying the gold cups 38 to the interstices. The screen 32 is also caused to adhere to the glass tubes 36, after which the layers 37, 33, 34 are removed by acid.

Title: Improvements in or relating to catalytic agents
IPC: B41J11/62
Filed: 1931-06-16
Abstract: The invention relates to catalytic agents consisting of a highly porous adsorbent carrier (e.g. silica gel) in the pores of which catalytically active material is deposited by reaction between a metal compound solution and a precipitating solution. According to the invention the metal compound solution is employed in excess, and the strength of the precipitating solution is so chosen that there is formed a plural precipitate consisting of two or more compounds of the catalytic metal.  The compounds may be precipitated in concentric rings within the pores of the gel. Activators may be precipitated simultaneously with the catalyst. The carrier may be a hydrogel composed of an oxide of silicon, germanium, chromium, tungsten, titanium, aluminium, tin, &c., or a partly dehydrated hydrogel or a fully dried hard porous gel, or a material such as fullers earth, kieselguhr, &c.  The precipitating solution may be a hydroxide of an alkali or alkaline-earth metal, or ammonium hydroxide, or a hydroxyl-containing amine, or an alkali carbonate or carbamate, or it may be a metallic salt such as potassium vanadite which is capable of reacting with a salt of another metal to form an active compound, or a non-hydroxyl-containing amine.  Suitable concentrations are 0,25-1 per cent in the case of a hydroxyl-bearing compound and 0,5-10 per cent in the case of a metallic salt.  The metal compound solution may be a salt of any catalytic metal, specified examples being iron, chromium, aluminium, gallium, indium, thorium, copper, cobalt, nickel, silver, gold, beryllium, magnesium, zinc, cadmium, mercury, lead, germanium, tin, titanium, zirconium, cerium, terbium, yttrium, bismuth, molybdenum, tungsten, uranium, manganese, ruthenium, rhodium, palladium, caesium, iridium, platinum, and vanadium, the last being preferred.  The Specification contains several specific examples, all relating to vanadium catalysts, of which the following is typical: a silica hydrogel is soaked in a 0,3 normal solution of potassium vanadite, then rinsed with water and immersed in a 0,1 N. solution of chromium chloride in slight excess of that required for precipitation.  The product is again rinsed and dried in air, first at 75-120 DEG  C. and finally at 300-400 DEG  C.  Specification 212,034, [Class 1 (i), Chemical processes &c.], is referred to.

Abstract: 1,120,511. Filing papers. HERBERT ZIPPEL K.G. 22 April, 1966 [23 April, 1965 (2)], No. 17743/66. Heading B6E. In a filing cabinet containing a number of tray-carrying shelves 6, Fig. 3, suspended from endless chains 3 and having means whereby the chains can be driven to bring the shelf carrying a required filing tray 12, Fig. 4, opposite to an access opening 1a, automatic means comprising lugs 15 can be operated to, engage pins or rollers 18, Fig. 4, on the tray to move the tray on to a work-bench 13. In one form, each tray 12 normally rests on the shelf bottom 11 between end walls 10. When a required tray is brought adjacent to the opening 1a by the operation of keys controlling a driving motor, the lugs 15, one at each end of the opening, are moved forward so that inclined edges 16 thereon engage the pins or rollers 18 on the tray so as to lift the front of tray over a retaining flange 24 on the shelf. Subsequently, the pins drop into notches 17 in the lugs and the tray is moved on to the bench 13. The lugs 15 are fixed to endless chains 14 or to toothed racks driven by a reversible motor. Rollers 23 mounted near the rear of the tray engage flanges 24, 25 on the shelf in the extreme positions of the tray. According to a modification, each tray has at its sides rollers running in tracks on the end walls of its shelf, the tracks, being shaped so that the inner edge of the shelf as well as its leading edge is lifted clear of the shelf as the tray moves forward. As a tray moves out through the access opening 1a, it depresses a spring-supported rod or roller 49, Fig. 10, so as to open a switch 53, in the circuit of the motor driving the chains 3, to ensure that the shelves remain stationary whilst the required tray is withdrawn. If the chains 3 are started with a tray not completely re-inserted on its shelf 6, that tray engages another spring-supported bar 48 to open another switch 53 and stop the motor. The bars 48, 49 may be part of a frame slidably supported along the edges of the opening 1a. The tray end walls 10, Fig. 3, are pivoted to the chains, the pivots 5 having arms 7 carrying rollers 8 engaging guides 9 to maintain the trays in a horizontal position.
