Title: Catalytic hydrogenation of nitriles to amines
IPC: C07C209/48
Filed: 1952-05-28
Abstract: Organic nitriles are hydrogenated to their corresponding amines in the presence of a catalyst, using a hydrogenating gas which contains 10-200 parts by volume of carbon monoxide per million parts of hydrogen.  Suitable catalysts are precipitated and pelletted salts of iron, cobalt or copper, or sintered oxides of these metals.  The carbon monoxide may be introduced with the hydrogenating gas or may be derived from compounds added to the reactants or deposited on the catalyst.  In examples, adiponitrile is hydrogenated to hexamethylenediamine using a cobalt catalyst (see Group III) at a temperature of 130-175 DEG C., a pressure of 100-700 atmospheres, and in the presence of ammonia. When using a fixed bed of catalyst, regeneration of the catalyst is effected by periodically stopping the introduction of carbon monoxide until the hot portion of the bed moves from the exit end to the inlet end.ALSO:In the catalyst hydrogenation of organic nitriles to their corresponding amines using a hydrogenating gas which contains 10-200 parts by volume of carbon monoxide per million parts of hydrogen (see Group IV (b)), the catalyst in the form of a fixed bed is regenerated by periodically stopping the introduction of carbon monoxide until the hot portion of the bed moves from the exit end to the inlet end.  Suitable catalysts are precipitated and pelletted salts of iron, cobalt, or nickel, or sintered oxides of these metals.  A cobalt catalyst is prepared by igniting precipitated cobalt carbonate to form the oxide, mixing with stearic acid ester to form pills, sintering in an oxidizing atmosphere, and reducing in hydrogen before use.

Title: Supercurrent structures and apparatus
IPC: G11C19/32
Filed: 1972-03-23
Abstract: 1370723 Superconductive devices WESTERN ELECTRIC CO Inc 23 March 1972 [26 March 1971] 13575/72 Heading H3X [Also in Division H1] In a superconductive weak-link structure, means are provided for forming preferred locations for vortices, each vortex comprising a circulating current supporting a single magnetic flux quantum. The preferred vortex locations may be produced in the following ways: (i) In a superconductor - insulator - superconductor (SIS) structure exhibiting Josephson tunnelling part of the insulation may be omitted, Figs. 4A to 4B (not shown); (ii) A pair of discrete SIS junctions may be connected in parallel in a loop, Fig. 5 (not shown); (iii) In an SIS structure the insulating layer may have a portion of increased thickness, Fig. 6 (not shown); (iv) In a uniform SIS structure a point magnetic source may be directed on to the edge of the insulating layer, Figs. 7A and 7B (not shown); (v) In a uniform SIS structure a local current may be passed between a pair of closely spaced points of one superconductor to generate a magnetic field threading the insulator, Fig. 8 (not shown); (vi) In a uniform SIS structure a second SIS plate having an insulator thickness sufficiently large to prevent Josephson tunnelling and a portion of reduced width may be placed along one edge to produce an area having less inductance than adjacent areas, Fig. 9 (not shown). Shift registers may be produced by arranging a plurality of preferred locations spaced by such a distance that only a single flux quantum vortex can reside at each location. The vortices may be injected by passing current between the conductors at one end of the structure or by means of an inductor inducing a magnetic field (Fig. 8). The vortices may be shifted from one preferred location to the next by injecting a further vortex by applying a control current between the superconductors at a point to one side of the vortex which is to be moved, or in the case of preferred locations formed by point magnetic sources these may be sequentially switched (Fig. 7B). As shown, Fig. 10A, a two bit shift register is formed on a glass substrate 102 on which is deposited a Sn ground plane 104 and an evaporated Ge layer as insulation. A layer of Sn is deposited to form a pattern 106 and is oxidized by subjecting it to a glow discharge. Sn strips 107, 108, 109 are evaporated-on to form two storage loops 113, 114 and two magnetometer loop. Silver shunts 110, 111, 112 are deposited across the active junctions to damp oscillations due to triggering. The superconductor material may also be Pb, Nb or Ta.

Title: Improvements in and relating to surgical sutures
IPC: A61L17/00
Filed: 1942-10-03
Abstract: An absorbable surgical suture carries, by impregnation or adsorption, a sulphonamide compound in order that absorption of the suture by the body tissues shall not take place before the p  wound &c. has healed. The suture, in one example, was exposed to a 0.4 per cent solution of sodium sulphathiazole in alcohol and a 0.8 per cent solution of sulphanilamide in water for 24 hours at 25 DEG  C.  After such exposure, the suture was dried, tubed in an anhydrous solution, e.g. xylene and finally sterilized by heat at 165 DEG  C. for 5 hours. The concentration of the sulphonamide compound introduced into the body tissues may range from 1 to 15,000 milligrams per cent.  In place of immersion, the suture, which may be of plain or chromic catgut, may be treated with the sulphonamide compound by spraying or dusting.

A device for analyzing the particle size of fine grain or pulverulent particles in a gaseous carrier medium includes a vortex separator 1 arranged to operate on a helical flow system having its outlet connected to a filter 3 and being provided with an auxiliary gas inlet whereby a gas may be introduced into the separator in a direction tangential to the helical flow and obliquely to the axis of helical flow said inlet consisting of one or more inlet ducts 7-14 which are adjustable as regards number, cross-section or pressure admission. The particles which are above a certain predetermined grain size are projected radially out of the flow by the rotation of the gas sample column into a particle collecting container 16. The purified gas passes through outlet 17 to filter 3 so that the particles which were not discharged in the vortex chamber 5 are collected in a filter bag 18. The gas sample flow entering the vortex chamber can be given an additional spinning effect by a spin imparting nozzle 20.

Abstract: 1,159,002. Wired boadcasting; colour television. COMMUNICATIONS PATENTS Ltd. 30 March, 1967 [30 March, 1966], No. 13992/66. Headings H4F and H4R. In a colour television wired distribution system the signal fed to the system comprises a modulated carrier brightness information together with a suppressed carrier colour information signal in respect of two colour information signals and a pilot signal of a frequency equal to the frequency of the suppressed carrier and which is modulated by one colour information component. At the receiver one colour component is derived by envelope detection of the pilot signal and the other by synchronous detection of the colour signal using a reinserted carrier derived from the pilot signal. The transmitter 1 comprises a receiver 16 of broadcast signals of a "PAL" system from which the brightness signal and suppressed carrier colour signals are applied to a modulator 20 to modulate a carrier of about 10.5 Mc/s from oscillator 21. The lower sideband is selected by vestigial sideband filter 23 and applied via mixer 24 to the lines 2 and 3. Colour bursts from the receiver are applied to synchronism oscillator 25 at the frequency of the original suppressed carrier of the colour signal, 4.43 Mc/s, which is modulated by one colour component in modulator 27 before being applied to the lines 2 and 3 via mixer 24. At the receiver 6 the brightness component is selected by filter 31 amplified by amplifier 32 and detected in envelope detector 33, from which the brightness signal is fed out over line 34 while the colour signals modulated on the subcarrier are fed to demodulator 36 via filter 35. The pilot signal, modulated by one colour component, is selected by filter 38 amplified and demodulated at 40 to provide one colour component on line 41, the pilot is also passed through a narrow band filter 44, selecting only the carrier, to provide a carrier for demodulating the other colour component in modulator 36, the phase of the carrier being reversed on alternate lines in phase switch 47, controlled by the colour recognition device 37, to demodulate the appropriate colour component from the colour information sub-carrier wave.
