Title: Improvements in the manufacture and production of organic compounds
IPC: C07C37/52
Filed: 1926-03-13
Abstract: 277,394. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 13, 1926. Aromatic hydrocarbons; phenols; alcohols.- Aromatic hydrocarbons or phenols or tar fractions containing them are converted into lower aromatic hydrocarbons or phenols by passing their vapour in admixture with more than twice their volume of water vapour at an elevated temperature over catalysts possessing both hydrating and dehydrogenating properties. The catlysts may be single substances possessing both properties or mixtures of substances, one of which possesses hydrating and other dehydrogenating properties ; nickel, cobalt, iron, copper. compounds of light metals (alkali, alkaline earth, and earth metals), zinc or its compounds, and difficulty reductible oxides of metals belonging to the fourth to seventh periodic groups, e.g. oxides of titanium vanadium, chromium, and manganese, are preferably present. The process is specially applicable to the treatment of fractions from coal tar, brown coal tar, and low-temperature tar, especially naphthalene and middle, oils, heavy benzol and creosote oil. which are transformed into benzene and its homologues. The starting materials, which are preferably freed from contact poisons such as sulphur, arsenic compounds, and metallic carbonyls, may be preliminarily hydrogenated. Temperatures of 300-700‹ C. and preferably 300-500‹ are employed; inert gases may be present. The gas mixtures obtained, which mainly comprise carbon dioxide and hydrogen are useful for the catalytic manufacture of alcohols. According to the examples, (1) o-cresol vapour and steam are passed over a catalyst prepared by soaking bauxite with copper nitrate and heating it in a current of hydrogen; a mixture of o-cresol and phenol is condensed; (2) naphthalene, freed from sulphur, is conducted in the vapour phase mixed with steam over a paste of nickel sesquioxide, alumina and china clay which has been reduced in hydrogen; on cooling the products an oil consisting of benzene and small quantities of its homologues separates out, whilst a mixture of carbon dioxide and hydrogen passes on; under other working conditions, homologues of benzene, e.g. toluene and o-xylene, may be obtained; (3) a mixture of naphthalene and phenols is vapourized and passed with hydrogen over a catalyst prepared by reducing a mixture of ammonium molybdate and zinc oxide; the resulting product is mixed, without cooling, with steam and passed over the catalyst described in the preceding example; the hydrocarbons formed during the first stage by reduction of the phenols become, converted, along with the naphthalene, into benzene and its homologues during the second stage.

Fig. 2 shows an embodiment in which the gas in chamber 12 is preloaded by pumps 36, 37 and a piston flange 31. This causes the hammer and cap to rebound to the starting position after each blow. An electronic transmitter 39 controls the pumps 36, 37. Figs. 3-5, (not shown), illustrate modifications in which the hammer is raised by a subsidiary hydraulic piston and cylinder arrangement.
Patent GB-746312-A (GB)
Title: Method for the purification of acrylonitrile
Filed: 1954-03-11
Abstract: Synthetic acrylonitrile containing lower polymers of acetylene (e.g. trimers, tetramers) is purified by adding nitrosyl chloride to convert the impurities into high boiling derivatives, and then distilling off the acrylonitrile.  The process is preferably carried out at room temperature with constant stirring, the nitrosyl chloride being introduced below the surface of the acrylonitrile in gaseous or liquid form.  The mixture is then neutralized with an alkali before distillation.  Any solid products formed can be removed by decantation or filtration.  A polymerization inhibitor such as hydroquinone may be added.  The process serves to remove acetylene polymers such as divinylacetylene and octatrienynes and also acetaldehyde resulting from the decomposition of lactonitrile.  The product is acid-free and is stable to polymerization.  Examples are given of the process.

Title: Staphylococcal vaccine
IPC: A61K39/085
Filed: 1961-02-27
Abstract: A staphylococcal vaccine is produced by extracting the intact cells of Staphylococcus aureus strains NRRL B-2467, NRRL B-2468, NRRL B-2469, NRRL B-2471, NRRL B-2472, NRRL B-2473, NRRL B-2474, NRRL B-2475, NRRL B-2476 or NRRL B-2477 with phenol and an aqueous solvent to obtain immiscible phenolic and aqueous solutions, e.g. water or an aqueous physiological salt solution, and separating the phenol and insoluble solid material from the aqueous solution to obtain an aqueous solution capable of stimulating the production of a protective antibody against Staphylococcus aureus. The cells of S. aureus may be alive, killed or partially killed. The extraction steps may be carried out separately or simultaneously.  In the case of simultaneous extraction, sufficient phenol is used to produce a phenolic phase but insufficient to dissolve all the aqueous solvent phase.  For separate extractions, the phenol must contain sufficient water to render the phenol liquid but insufficient to cause separation of a separate aqueous phase i.e. 5 to 30 and preferably 15% water.  The final aqueous product should contain not more than 0.2% phenol. Excess phenol is removed by (a) dialysis or (b) extraction with a volatile water-immiscible organic solvent for the phenol e.g. ether or chloroform.  The pH of the vaccine may be adjusted to 6 to 8 and preferably pH 7.2.  If necessary, it should be made isotonic with sodium chloride.  It is sterilized for parenteral injection.

Title: Methods of manufacturing monograin layer devices
IPC: H01L31/02
Filed: 1973-02-16
Abstract: 1421459 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 Feb 1973 [19 Feb 1972] 7724/73 Heading H1K A semi-conductor device, e.g. a solar cell or injection luminescent light source is made by first forming a monolayer of semi-conductor grains surface layers of which form PN junctions with the cores, the grains being embedded in a binder layer over part of its thickness but projecting from one face of it. After depositing a first electrode layer on the exposed parts of the grains parts of the surface layers and cores are removed, insulation selectively provided to cover the exposed parts of the surface layers but leaving parts of the cores exposed, and a second electrode layer deposited to contact these exposed parts. The grains, which are typically of gallium phosphide and of 50 Á diameter with 5 Á N type surface layers, may be formed into a monolayer by attaching to a glass plate with a thin layer of rubber glue, covering with polyurethane and then stripping the latter with the grains from the substrate and glue and increasing the exposed area of the grains by dissolving away some of the polyurethane. Then the first electrode layer of gold is vapour deposited and covered with a thick layer of polyurethane and the resulting surface ground down until the cores of the grains are exposed. In one method insulation is then selectively deposited over the exposed gold and surface layers with the PN junctions reverse biased either by electrophoresis from an aqueous solution of synthetic resin containing carboxyl and/or hydroxyl group, e.g. epoxy, alkyl or acrylate resin, and ammonia, or an organic aminemelamine based resin (if the surface layers are P type) or by electrochemical polymerization from a mixture of orthoisopropyl phenol and triethylamine in a 10 : 1 mol. ratio. In the first case the layer is cured by baking. Alternatively after the grinding process the polyurethane is exposed to ethyl acetate vapour which causes it to swell so as just to cover the junctions where it remains on evaporation of the acetate. Finally the second electrode is deposited on the resulting surface. Provision of the first electrode on the other side of the monolayer and the use of zinc selenide, gallium arsenide phosphide and gallium aluminium arsenide grains are also suggested.

Title: Damping electrically operated vibration devices
IPC: H04R3/00
Filed: 1926-03-20
Abstract: 272,622. Sykes, A. F. March 20, 1926. Magnetic instruments,. telephone systems. - The vibrating member of electrically-operated acoustic sound-recording and like devices is controlled or damped by causing it, or another member moving therewith, to generate by its movement a current or potential which is amplified and with suitable phase adjustment superposed on the main current for operating the vibrator, whose movement is thereby controlled with damping effect in accordance with the amplification and phase adjustment of the controlling current or potential. Fig. 1 (Prov.) shows the arrangement applied to the sound recording apparatus described in Specification 210,956 wherein the stylus bar 3 is connected to a conductor 1 in the circuit of the secondary winding 85, constituted by copper strips on edge separated by shellac, of a transformer having a laminated core 88 and a primary section-wound winding 141. The winding 5 has a rubber bush 335 mounted on a pivot 336 and carries an adjustable counterweight 73. In applying the invention to this arrangement. the controlling potential is generated in an additional conductor insulated from and moving with the conductor 1 in the magnetic field 80, and the current generated therein is amplified by passing to a transformer 406 and one or more thermionic valves 44, 45, whose output circuit is provided with means for varying the phase to effect lead or lag before the current passes to a power valve 47 which is connected with and supplies the operating power to the primary winding 141. These phase-varying means comprise a variable resistance 107, a variable inductance 408 and a variable condenser 409 which may be combined as desired by switches to pass a current which when superposed on the operating current will produce the desired controlling or damping effect on the main conductor 1. The range of this controlling current may be localized by electric. filters. As applied to a loud-speaker having a vibratory coil 32, Fig. I (Comp.), mounted between pole-pieces 33, 34 on a, projection from the tone-reproducing surface 29 and supplied with current from a four-electrode valve 416, an additional coil 403 in which the controlling current is generated is arranged in the magnetic field and connected through a counter-wound fixed coil 417 with one of the grids of the valve 416 so that its effect is superposed on the operating current. The means described for varying the phase may be interpolated. In another arrangement for generating the controlling or damping current, an electrically operated vibrator acts on a microphone, and in a further arrangement applied to a Bell telephone, auxiliary poles are provided between the main poles, the current generated in such auxiliary circuit being amplified and modified as described above and superposed on the operating current. Damping may be assisted by known damping means. Specifications 160,223, 253,159 and 263,502 also are referred to.
