Title: Improvements in feeding devices for strips bearing sound records
IPC: G11B15/28
Filed: 1938-02-03
Abstract: 497,461. Sound-film speed-controlling devices. BAUER GES., E. Feb. 3, 1938, No. 3330. Convention date, Feb. 5, 1937. [Class 40 (ii)] In sound-film apparatus in which a " scanning drum" a, associated with a flywheel b for maintaining uniform speed, is driven by the film, film-guiding rollers g, h, so located that they are respectively engaged by the film before and after it passes over the drum a, are interconnected by a rigid member k in order to ensure simultaneity of movement, and are displaceable by the action of the film tension. The member k is, in the construction shown, a two-armed lever mounted in ball bearings on the shaft i of the drum. A compensating weight k<1> keeps the lever in equilibrium in every position. Stops r, s limit the oscillations of the lever k when the drum and flywheel start to rotate, and a brake (not shown) may act on the lever to shorten the oscillations.

IPC: C07C37/14
Filed: 1928-08-30
Abstract: 325,856. Rheinische Kampfer-Fabrik Ges. Oct. 12, 1927, [Convention date]. Divided on 298,600. Thymol and its isomers; di-propyl and diisopropyl-m-cresols. - Thymol is produced by reacting m-cresol and propylene in the gaseous phase in presence of a dehydrating catalyst such as alumina, aluminium phosphate, and thorium and tungsten oxides, and they may be used alone or on carriers such as pumice, Kieselguhr, asbestos, silica gel and active charcoal; dried kaolin, brick clay, and highly porous materials such as Florida, fuller's, and silica earths, and the materials sold under the registered Trade Marks " Frankonit " and " Tonsil " (which are probably hydrosilicates of magnesium and aluminium) and also anhydrous zinc and magnesium chlorides, anhydrous acids and acid anhydrides, such as phosphoric and sulphuric acids, phosphoric anhydride, and mixtures of any of these substances may also be used. Instead of propylene, substances which are decomposed by the catalysts into propylene and water, such as propyl and isopropyl alcohols and ethers may be used. The propylene and cresol vapour may be passed over the catalyst at 200-380‹ C., and ordinary, increased, or diminished pressure may be employed. Besides thymol, two isomers (3- oxy-1-methyl-x-propyl or isopropyl benzene) melting at 69‹ C. and 112‹ C. and boiling at 228.5‹ C. and 245-246‹ C. are also produced. In an example, a mixture of m-cresol vapour and excess of propylene or half the equivalent quantity of propyl or isopropyl alcohol, or a quarter of the equivalent quantity of propyl or isopropyl ether over " Tonsil ' at a temperature above 230‹ C. The condensate is fractionated, the fractions being (1) unchanged m-cresol, (2) thymol isomer of melting-point 69‹ C., (3) thymol (which is purified by recrystallization from benzine), (4) thymol isomer of melting-point 112‹ C. and (5) a mixture of dipropyl di-isopropyl m-cresols boiling at about 260‹ C. At higher temperatures the yield of thymol decreases and the yield of dipropyl and di-isopropyl m-cresols increases. Specification 293,753 is referred to.

Abstract: 368,269. Electric systems for transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and COATES, H. J., of General Electric Co., Witton, Birmingham. Oct. 21, 1930, No. 3500/32. Divided on 366,067. [Class 38 (iv).] In a ship propulsion system where overloading of alternating current generators or motors may occur under certain running conditions the speed of the generators is limited when one or more generators or motors is inoperative. Auxiliary switches 1 .. 4, each associated with switching means governing the state of one of the motors and closed only when the motor is inoperative, and auxiliary switches 5, 6, each associated with switching means governing the state of one of the generators and closed only when the generator is inoperative, are connected in parallel with each other. These auxiliary switches are in series with electrically operated devices 10, 21 controlling the governor setting of the prime movers. Thus with a generator or one or more motors inoperative the speed of both generators is limited. The invention is described in association with further auxiliary switches 11, 12, each associated with a generator and closed only when the generator is operative, which control electrically operated devices 13, 14 controlling the throttle valves of the prime movers to limit the power output when the maximum power of the generators exceeds that of the motors in use.

Abstract: 1413287 Natural gas substitute IMPERIAL CHEMICAL INDUSTRIES Ltd 11 Jan 1973 [26 Jan 1972] 3685/72 Heading C5E A natural gas substitute is produced at least partly from a hydrocarbon of higher molecular weight than methane in a first catalytic stage in which methane or a hydrocarbon of higher molecular weight than methane is reacted with steam over an externally heated steam reforming catalyst at an outlet temperature of 600- 900‹ C. to give a first gas containing carbon oxides, hydrogen and methane, the methane content of the gas being less than 30% by volume on a dry basis; a second catalytic stage in which the first gas, steam (residual and/or added) and hydrocarbon feedstock of higher molecular weight than methane are reacted together over a steam reforming and methanation catalyst to give a second gas having a methane content greater than that of the first gas and 20-40% by volume on a dry basis; and a third catalytic stage in which the second gas is reacted over a methanation catalyst at an outlet temperature of 250-450‹ C. in heat exchange with boiling water generating steam at a pressure of at least 35 atm. or with co-, currently flowing cool feed gas, whereby heat is continuously removed from the process. For heat exchange with boiling water, the third stage catalyst may be in tubes of internal diameter 20-75mm. and the hydrogen content of the feed gas to that stage may be over 15%. For co-current heat exchange, the third stage catalyst is in one or more tubes 10-60 mm. in diameter or in a space surrounding such tube or tubes and the hydrogen content of the feed gas to that stage is 8-20%. Steam may be removed from the second gas such that the gas feed to the third stage contains under 15% steam. Carbon dioxide may be removed from the second gas, e.g. such that the feed gas to the third stage contains 2-6% carbon dioxide. The second gas may be compressed before being fed to the third stage.

Filed: 1927-02-11
Abstract: 293,810. General Gas Appliances, Ltd., and Coleman, F. S. Feb, 11, 1927. Thermostats.-A valve g, chiefly for use with gas cookers, is directly operated by a thermostat j, h<1> and a return spring g<1> through adjustable setting mechanism comprising two balls m<1>, m<2> in a guide k and a spacing or positioning member k<1> for the balls. The circular valve casing a is divided into two parts, communicating with the inlet and outlet pipes respectively, by a circular partition d against which the disc valve is forced by the spring. A long brass tube h' extends from the back of the casing into the oven and has fixed to its end a non-expansible rod j the other end of which bears against the steel ball m'. The guide k for the balls comprises a slotted tube screwed into the valve casing and the spacing member k<1> comprises a wedge-shaped plate extending through the slot between the balls and slidably resting upon the end of a screwed spindle m arranged at right angles to the thermostatic rod j. The ball m<2> bears against a recess in the centre of the disc valve g, and the spindle m engages a tapped hole in the centre of the disc valve g, and the spindle m engages a tapped hole in the casing rendered gas-tight by packing p held in place by a spring o. Outside the casing the spindle m is fitted with a handle n and pointer n<1> co-operating with a dial n<2>. On rotating the handle the wedge-shaped plate k<1> is adjusted and the setting of the valve altered. An adjustable bye-pass q is provided to prevent extinction. Fig. 7 shows a modification in which the valve is arranged in a plane parallel to the thermostatic rod j and engages with the threaded spindle m, rotation of the valve when the spindle is turned being prevented by a pin v, and free axial movement of the valve being allowed by a pin-and-slot coupling m', v<1>. The parts are rendered gastight by spring-pressed discs w, w<1>. In a further modification similar to Fig. 7 the ball m<1> acts upon the valve, the two balls and the spacing member being moved bodily with the valve when the spindle m is turned. The wedge-shaped plate may be replaced by another steel ball, the guide k being suitably modified.
