Title: Manufacture of organic silicon compounds with the aid of improved catalysts
IPC: D01G15/84
Filed: 1950-01-25
Abstract: Alkyl or aryl halogenosilanes are prepared by the reaction of an alkyl or aryl halide with a silicon alloy at a raised temperature wherein there is used an alloy of silicon with copper and a metal or other alloyable element of groups 5 to 8 of the periodic system, e.g. iron, cobalt, nickel or phosphorus, the said alloy being activated with a finely powdered metal of specific gravity greater than 5, or with a salt or salt-forming acid of such a metal, e.g. copper, cuprous chloride, a copper hydrochloric acid, i.e. H(CuCl2) or H(CuCl3), or a salt thereof. The activator may consist of a plurality of salts of a metal of specific gravity greater than 5 which may contain the metal in different states of valency.  The activator may contain the metalliferous residue which remains behind after the alloy has been reacted.  The valency state of the activator may be produced before or during the reaction.  The silicon alloy may be prepared by fusing the components together under hydrogen or a compound liberating hydrogen, e.g. gaseous ammonia.  It is preferred to introduce the activator in the form of a paste, spray or solution, e.g. the paste obtained by mixing cuprous and cupric chloride with conc. nitric acid.  The preferred reaction temperature range is from 200 DEG  to 450 DEG  C.  Gaseous hydrogen chloride in an amount equal to 1 to 15 per cent based on the weight of alkyl or aryl halide may be added during the reaction.  In examples: (1) ethyl chloride is reacted with an alloy of silicon, copper and cobalt which is mixed with a mixture of cuprous chloride and cupric chloride; (2) methyl chloride is reacted with the alloy of (1) which has been treated with the acid H[CuCl2]; (3) methyl chloride is reacted with the contact mass of (2) which has been mixed with pyrophoric copper (prepared by reducing cupric oxide with hydrogen or reacting the conversion mass used in the present process with hydrogen halides); (4) methyl chloride is reacted with the contact mass of each of examples 1 to 3 in the presence of hydrogen chloride; (5) methyl chloride is reacted with an alloy prepared from ferrosilicon and copper which has been treated with the acid H[CuCl2].

Title: Improvements in or relating to sound recording and reproducing
IPC: G11B7/00
Filed: 1938-01-22
Abstract: 503,268. Reproducing sound. RADIO CORPORATION OF AMERICA. Jan. 22, 1938, No. 2181. Convention date, Feb. 27, 1937. [Class 40 (ii)] In reproducing sound films a single image of the sound track is scanned, for high frequencies, in a narrow line and, for low frequencies, in a wider line. Light from a lamp 10, Fig. 1, is concentrated by an optical system 11 on the sound track 12 in a band of width suitable for reproduction of low frequencies and lenses 13 focus an image of the track on a mirror 14 which bears a narrow slit 15. This slit is of such a' width as to reproduce correctly frequencies above a determined minimum and light passing through it is directed to a photoelectric cathode 16. The remainder of the light beam is reflected from a mirror 20 to a second cathode 21. Through switches 24, 25 the outputs of the two photo-electric elements are passed to the primary windings 18, 23 of an output transformer. The response of the apparatus is far greater in the lower frequencies and consequently in making suitable records the lower frequencies have to be suppressed to an appropriate extent in order that the final reproduced sound may have its correct amplitude variations. A special gate is provided in order that the apparatus may be used with normal or push-pull records. A frame 33, Fig. 2, sliding in a holder 34 carries a mirror 14 bearing a slit 16 for use with the special records described and, in addition, two opaque, non- reflecting surfaces 39, 40 between which is a reflecting surface 42 and a slit 41. The frame 33 is moved laterally by solenoids 46, 46 connected to a switch 26, Fig. 1. The operating arms of the three switches 24, 25, 26 are so connected that the apparatus may be used for (1) the special records referred to, (2) pushpull records, and (3) normal records. In the latter two positions the connections are such that the slit bearing frame 33 is moved to the left in Fig. 2, so that a centrally divided narrow beam is used, each half being directed to a separate photo-sensitive cathode.

Title: Improvements in or relating to work ejecting mechanism for machines for performing pressure-applying operations on shoe parts
IPC: A43D83/00
Filed: 1941-02-20
Abstract: 547,293. Compressing heels &c. BRITISH UNITED SHOE MACHINERY CO., Ltd., and MINETT, W. T. Feb. 20, 1941, No. 2308. [Class 17 (i)] Relates to the work ejecting mechanism in machines of the kind described in Specifications 22839/02, [Class 17], and 11454/11, [Class 17 (i)], and consists in the provision of a link 26 between the frictionally controlled rod 16 described in the later prior Specification and the lever 12 actuating the ejector, and the provision of a stop device 40 also actuating the lever, this stop causing the lever to rise with the head in the first part of such rise. The lever 12 is pivoted to a bracket 6 secured to the rising and falling head 2, which is shown in its lowest position. A link 26 connects the lever with a rod 16 against which a friction pad 18 carried by a fixed part of the machine frame is urged by a spring 24. The rod 16 has a head 14 co-operating with a yoke 28 pivoted at 27 to the frame, and urged anti-clockwise by a spring 29. A cam 30 carried by the head co-operates with a lug 32 on the head 14 and the yoke 28 as it rises and falls, respectively. A stop 40 is pivoted at 41 to the bracket 6, is urged clockwise by a weight 52, and is released by a stem 48 when this is engaged by a fixed face 50. In operation, as the head rises the rod 16 is pulled up by the lever, then supported by the stop 40 until this stop is released by the stem 48 engaging the face 50.
