Title: Improvements in or relating to solid-state image intensifiers having optical feed-back
IPC: H01L31/14
Filed: 1959-08-11
Abstract: 921,235. Electroluminescence. PHILIPS GLOEILAMPENFABRIEKEN N.V. Aug. 11, 1959 [Aug. 13, 1958], No. 27479/59. Drawings to Specification. Class 39 (1). A solid state image intensifier comprising radiation-sensitive variable-impedance elements together with electroluminescent elements has two kinds of differently luminescing elements, one kind providing the radiation for the observable image and the second providing radiation for feed-back to the variable-impedance elements. A layer of the second kind of electroluminescent element, which may be fieldenhanced, may be interposed between a layer of the first electroluminescent material and a photo-conductive layer, or there may be a plurality of photo-conductive layers with feedback emitting electroluminescent layers between each such layer. A suitable material of the second kind is red electroluminescent cadmium sulphide or sulphoselenide, or silver and manganese activated zinc sulphide whose luminous output when struck by X-rays is enhanced by the applied electric field. Specification 713,916 is referred to.

Title: An improved process for preserving perishable goods
IPC: A23B7/16
Filed: 1927-10-17
Abstract: 302,447. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 17, 1927. Antiseptics.-Perishable goods, such as eggs, fruit, &c. are preserved by treating with an aqueous solution of a condensation product of urea and formaldehyde and then drying, a thin impervious coating being obtained. The condensation product obtained from dimethylolurea, e.g. by boiling its aqueous solution with or without the addition of condensing agents may be used. Small amounts of organic water soluble solvents, such as ethyl alcohol, glycol, glycerine and other aliphatic alcohols, may be added to the solution. Benzoic, salicylic or boric acid or other preservatives may also be added. A small amount of free formaldehyde is also usually present and acts as a preservative. The solution contains generally 10-30 per cent of the condensation product.

In one form of the instrument a reservoir a has its lower part b of rectangular cross section while the remainder of the reservoir has the front wall c indented to a V-shape as shown in Fig. 5 so as to leave the portion b projecting like a shelf. A frame d, Fig. 3, has a cross section similar to that of, and forms a con tinuation of, the part c of the reservoir. The upper end of the frame has an endplate apertured to receive a gauge glass h which is held by a nipple and screw cap in the endplate. The reservoir is provided with a valve n as described in Specification 395,153, and with a nipple o, Fig. 5, for connection with an airsupply pipe.

Title: Disproportionation catalysts
Inventor: BRADSHAW CHRISTOPHER PATRICK C
IPC: B01J23/36
Filed: 1966-06-21
Abstract: Acyclic olefins are disproportionated in the presence of Re2O7 on SnO2, ThO2 or ZrO2. Typical reaction conditions are - 20 DEG  to 500 DEG  C., 0 to 200 p.s.i.g.  G.H.S.V. 500 to 5000 v./v.  Olefins mentioned are C3- 30 alkenes; specified olefins range from propylene up to octenes.  An example describes the disproportionation of propylene to ethylene and butene-2.ALSO:Disproportionation catalysts are made by dissolving in water a soluble compound of an element of Group IV of the Periodic Table, which element forms a refractory oxide, precipitating the hydroxide on the oxide of the element from aqueous solution, converting the hydroxide to the oxide if necessary, isolating the oxide, passing a stream of carrier gas over the oxide and heating Re2O7 on a precursor therefor in the stream of carrier gas upstream of the Group IV oxide whereby Re2O7 is deposited thereon.  Specified oxides are ZrO2, ThO2 and SuO2.  Only the use of the latter is exemplified.  The catalyst may be activated by heating in air or an inert gas.

Title: Improvements in and relating to the production of thiophene
IPC: C07D333/10
Filed: 1939-10-12
Abstract: 535,583. Thiophene. ARNOLD, M. H. M., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 12, 1939, No. 27736. [Class 2 (iii)] Thiophene is prepared by reacting acetylene and hydrogen sulphide or mixtures containing these materials at elevated temperature in the gaseous phase in the presence of a water-insoluble, water-stable metallic sulphide catalyst. The materials must be free from ammonia and/or ammonium compounds. Suitable catalysts.mentioned include the sulphides of lead, manganese, copper, tin, cobalt, nickel and molybdenum. The catalyst may be used in pellet .form or on a porous support such as activated alumina or pumice. The proportions of acetylene to hydrogen may be the theoretical ones of 2:1, but less carbon and tar are formed if the proportions are 4:3 or 2:3. Water should be absent. The reaction should be carried out at temperatures from 500‹ C.- 750‹ C. and may take place in stages, by removing the thiophene by condensation and then adding a further quantity of acetylene to the resulting gas before passing again over a catalyst. In examples (1) a mixture of equal volumes of acetylene and hydrogen is passed over a catalyst of manganese sulphide on a porous alumina support at 650‹ C., at a rate of 50 volumes per volume of catalyst space to give a product which condensed to a liquid consisting of 60 per cent. thiophene. (2) To the residual gases from example (1) which contained 27 per cent. by vol. of acetylene, 52 per cent. by vol. of hydrogen sulphide and 15 per cent. by vol. of hydrogen were added enough acetylene to make the acetylenehydrogen ratio equal and the mixture passed over the same catalyst at 700‹ C. to give a similar product to that obtained in example (1).

Title: An improved method of producing artificial leather
IPC: D06N3/00
Filed: 1935-10-10
Abstract: Thin layers of polyvinyl resin for use in making artificial leather are produced by rolling the resin between heated rollers, pressing between warm metal plates, cutting from a block, or applying an aqueous dispersion of the resin to a fabric. Polyvinyl chloride or acetate, chlorinated polyvinyl chloride, and interpolymers of vinyl chloride and vinyl acetate, acrylic or methacrylic esters or acrylic nitrile, are suitable resins. Softening agents such as dibutyl phthalate, tricresyl or triamyl phosphate, and sleeking substances such as waxes, stearic acid or stearates, stearyl, oleyl, or wool fat alcohol, and talcum, may be added.  An interpolymer of vinyl chloride and methyl acrylate worked up on heated rollers with dibutyl phthalate and, if desired, wax, is rolled out into thin films. Chlorinated polyvinyl chloride plasticized with tricresyl phosphate may be similarly made into films.

The process can be carried out by introducing a dispersion of oil solution and solid urea into the central portion of a decanting column, withdrawing a solids-free solution of the dewaxed oil from the upper end of the column, and withdrawing the dispersion from the lower end of the column (e.g. after an average-residence of 10-80 minutes at 25-45‹ C.) by means of a pump and recycling it to the central portion of the column after dividing a partial stream from the dispersion. The partial stream is separated into a solids-free stream, which is either combined with the solids-free solution withdrawn from the top of the column or returned to the circulating dispersion, and a solids portion which is decomposed by heating or extraction with fresh solvent to recover urea, which is recycled to the column, and n-paraffins.
