Title: Improvements in the manufacture and production of catalysts of high mechanical stability
IPC: B01J37/00
Filed: 1928-12-24
Abstract: 326,580. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 24, 1928. Catalytic agents, preparation of.-Non-metallic catalysts used in the destructive hydrogenation of carbonaceous materials, such as oxides or hydroxides of metals of the sixth group of the periodic system, for example chromium oxide, molybdic acid or tungstic acid or sulphides, carbides or solid metalloids and possessing little mechanical stability, for example those of a pulverulent or mealy nature, are converted into a stable, coherent form by incorporating therewith a small quantity of finely divided metals of the second or third groups of the periodic system such as zinc, aluminium; beryllium, cadmium or the earth metals of the said groups or alloys or carbides thereof, either alone or mixed. Other substances, such as metal salts, alkali metal salts or hydroxides or substance having an acid reaction in aqueous solution, for example soluble magnesium compounds sch as magnesium chloride, may be added. The hardening agent is mixed with an aqueous paste of the constituents of the catalyst and subjected to an intensive mechanical intermixing treatment such as kneading, during which the temperature is kept below 50‹ C, and then gradually dried. The added substances may be removed after stabilization of the catalyst by washing or heating to a high temperature. In an example the production of a stable and hard catalyst for the destructive hydrogenation of hydrocarbons by kneading an aqueous part of molybdic acid and zinc oxide with 1 to 3 per cent of aluminium powder or powdered aluminium bronze is described.

Abstract: 967,063. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 4, 1960 [Nov. 12, 1959], No. 38341/59. Heading H1D. A target in an image pick-up tube comprises a secondary electron-emissive layer, e.g. of magnesium oxide or potassium chloride, facing a photo-emissive cathode and supported on a layer of a metallic oxide, the layers being sufficiently conducting in relation to their thickness to allow charges on the secondary-emissive layer to leak through to the opposite surface of the supporting layer which may be scanned so as to generate signals. The supporting layer may be of aluminium oxide, beryllium oxide or iron oxide. The target may be made by coating one side of a sheet of aluminium foil with a lacquer and anodizing the foil. After removing the lacquer the remaining aluminium foil is etched away and the resulting layer of aluminium oxide is secured to a metal supporting frame. Finally, magnesium is evaporated on to the aluminium oxide layer and oxidized, the total target thickness being between 200 and 750 Š.

Abstract: 394,440. Time checks for games. FORTE, D., 35, Market Street, Galashiels, Selkirkshire, and BIZERBA AUTOMATIC SCALES, Ltd., 12, Holborn Viaduct, London. March 3, 1932, No. 6394. [Class 132 (ii).] A time check for games such as billiards comprises a disc 31, Fig. 1, rotated about a horizontal axis 32 by clockwork and provided around its periphery with a series of slots 34 adapted to receive tokens 35 that are introduced into the slots from a point above the disc and fall out of the slots after a rotation of the disc corresponding to a predetermined time interval, the arrangement being such that the angular position of each token on the disc relative to a fixed dial 39 indicates the time in play and the time to be played in the corresponding game, while the number of tokens carried by the disc is indicative of the number of games in progress. The tokens are formed as peripherally-grooved discs and are numbered to correspond with the billiard tables. At the beginning of a game the appropriate token is taken from a rack 41 and inserted in a guideway 53. The passage of the token down the guideway is interrupted by a slide 54 until a slot 34 is positioned beneath the guideway by the rotation of the disc, when the token is released and falls into the slot. The token is retained within the slot by a flange 62 and co-operates with the dial 39 to indicate in minutes the time still to be played. At the expiry of half an hour the token falls from its slot into a delivery guideway 40, where it is retained by a plunger 42, Figs. 1 and 6. The tokens are released one at a time for removal from the guideway by depressing the plunger whereby a slot 44 therein is positioned below the lowermost token and prongs 45 below the next higher token. Depression of the plunger is prevented, when no token is present, by a spring-urged slide 48 adapted to intercept one of the prongs 45. A totalizer provided with reset and non-reset wheels is operatively connected to the plunger. An electric buzzer is sounded as the token passes into the delivery guide way.

Title: Process for conditioning fibrous materials films and extrusions to render them dye receptive and materials conditioned by the process
Inventor: DABROWSKI JAN
Filed: 1960-11-21
Abstract: Fibres or films are rendered dye receptive by applying an aqueous solution of a Wernertype reactive chromium complex and a watersoluble acid salt of deacetylated chitin and then heating to cure the so-applied dye receptive surface.  The process is applicable to yarns and fabrics of glass fibres, yarns, fabrics and films of polyolefins, yarns and fabrics of acrylic polymers, vinylidene/vinyl chloride copolymers, polyesters, polyamides, cellulose acetate, cellulose triacetate, saponified cellulose acetate and also to silk and wool. The so-treated materials may then be dyed with reactive, chrome, acid, direct, sulphur, vat, indigosol, basic, disperse acetate and naphthol dyes.  Specified reactive chromium complexes are p-aminobenzoato chromic chloride, betaresorcylato chromic chloride, glycinato chromic chloride, tannato chromic chloride, glycolato chromic chloride, thioglycolato chromic chloride and sorbato chromic chloride. Specified acid salts of deacetylated chitin are the acetic, itaconic, formic, pyruvic and lactic acid salts.  Discharge effects on the treated and dyed fabrics may be effected by the application of an acid, e.g. sulphuric or hydrochloric acid, although in one example, an acrylic fabric treated and dyed with a reactive or chrome dye is discharged in selected areas with sodium formaldehyde sulphoxylate.  Numerous examples of treating and dyeing are given, and in one example, a glass fibre fabric is treated and printed with a paste containing a reactive dyestuff, urea and an emulsion thickening.  Specification 458,839 is referred to.
