Title: Improvements in and relating to safety devices for gas-heated appliances
IPC: E05F11/34
Filed: 1935-03-18
Abstract: 452,315. Valves. JUNKERS & CO., GES., 35, Junkersstrasse, Dessau, Anhalt, Germany. March 18, 1935, No. 8403. Convention date, July 27, 1934. Addition to 384,200. [Class 135] A modified form of back-draft safety device for water heaters as described in the parent Specification comprises a thermocouple C situated in the path of the backdraught gases and adapted on being heated by the gases to generate a current which wholly or partially neutralizes the current generated by a flame - heated thermocouple actuating a magnetic valve controlling the main gas supply. In one form, Fig. 2, lighting of an ignition jet 24 heats a thermocouple B which causes energization of a slidably - mounted electromagnet 19. Depression of the magnet 19 against spring pressure causes the main valve 23 to be attracted thereto so that when the magnet is released it lifts the main gas valve. The thermocouple C is in parallel with the couple B and acts to neutralize the effect thereof on the coil of the electromagnet when back-draught gases heat the couple C, so that the main valve closes. In another form the couple C is in series with the couple B but acts oppositely thereto and the valve is of the form described in Specification 452,304. The passage to the ignition jet 24 may be on the outlet side of the main valve, the initial supply of gas to the jet being through a passage in the magnet core which is open while the core is depressed. The electromagneticallyoperated valve may control the gas pressure in a subsidiary gas pipe so as to actuate the main valve.

Abstract: 328,387. Royce, F. H. March 15, 1929. Ball joints. - A link connection between the axle and the operating arm of a shock absorber mounted on a motor vehicle is of the type in which ball and socket joints are arranged at the ends of the links and is constructed in such a way that a single spring forces the sockets at both ends of the link into engagement with the balls. The body of the link consists of a tube which is secured to or carries the outer sockets d<1>, il. The inner sockets f, g<1> are forced apart by the spring f<2> which acts directly on the socket f and transmits a push to the other socket g<1> by means of the internal tube b. With this construction the operating force is only transmitted through the spring f<2> when the link is compressed, and the amount the spring may yield before a, solid thrust is transmitted depends upon the size of the small gap j.

Abstract: 840,098. Pulse direction finding and echo ranging systems. BENDIX AVIATION CORPORATION. March 17, 1958 [April 8, 1957], No. 8526/58. Class 40 (7). [Also in Group XXXVI] Apparatus measuring the time interval between the starting times of two pulses comprises two normally inactive oscillatory devices of similar frequency, means applying the pulses to the respective devices to shook excite them into emission of respective oscillatory wavetrains and means for measuring the phase displacement between such wavetrains. Input pulses displaced in time are applied over inputs 10a, 1 (Fig. 1), to oscillation generators 10, 11 of identical frequency which may comprise inductance-capacitance tuned circuits (Fig. 2, not shown) or triggered self-sustaining oscillators generating trains of oscillation of phase difference proportional to the input pulse time interval, which are fed to a phase comparator 12 energizing a time interval indicating meter 13. The input pulses may be derived (Fig. 3) from transducers 16, 16<SP>1</SP> responsive to space wave pulses having wave fronts in the plane 15, which feed detectors 17, 17<SP>1</SP>; the relative time displacement of the pulses being a measure of the angle of approach of the space wave relatively to the laterally-spaced transducers (Fig. 4, not shown) which may be responsive to radio, sound, or light waves. The detectors are unnecessary if the transducer waves are of lower frequency than the oscillator waves whose phase angle is compared. Fig. 5 shows apparatus for measuring the distance of an aircraft from the ground or of a vessel from the bottom of a body of water utilizing respectively electrical or acoustical signals which are transmitted from directional transducer 21 excited by pulse source 20 and are reflected from the boundary 23 to directional receiving transducer 21<SP>1</SP>. The exciting signal from 20 is attenuated at 22 and rectified at 17 to pulse excite oscillator 10, while the received signal from 21<SP>1</SP> is rectified at 17<SP>1</SP> to pulse excite oscillator 11; the oscillations of identical frequency being phase-compared at 12 to produce an indication at meter 13 representing the time of travel from transducer 21 to boundary 23 and transducer 21<SP>1</SP> and thus the distance from the transducers to the boundary.

Filed: 1925-03-31
Abstract: 246,350. Dyson, H. W. C. K., Askham, S. J., and Palin, J. C. March 31, 1925. Piles, driving.-Piles are driven by means of a heavy or secured anchorage carrying a vertical or upwardly inclined tie member or members with pressure exerting means on the tie members which exert continuous or substantially continuous pressure, without impact, on the head of the pile or of a portion thereof of considerable length. The anchoring means may consist of girders let into an existing structure, and the pressure exerting means may be a hydraulic ram or jack, a winch, sheave or pulley blocks, winding gear or other apparatus. The anchorage may consist of beams a, Fig. 2, connected by cross beams a', sunk below the ground and let into existing walls. Vertical beams c constitute tie members secured to the anchorage, and are supported at the upper end by beams d carried by other beams d' let into the existing walls. Carried by the tie members c is a cross-head e which provides an abutment for a hydraulic ram or jack f which exerts pressure on the head of the pile z. The cross-head e is detachably mounted so that it may be lowered as the pile is driven. In the arrangement shown in Fig. 4, the anchorage comprises girders h connected by cross beams h<1> and let into the existing wall b. The free ends of the girders h are loaded with weights h<2> and the top of the tie member i is connected to the base girders h by inclined struts j, and may be further stayed by guy ropes secured to pegs in the ground. In another modification the anchorage consists of a heavily loaded truck l, Fig. 7, carrying weights l<2> and mounted on rollers or wheels l<1>. The tie member consists of vertical beams m braced to the truck by struts n. The tie member carries the cross-head n<1> between which and the head of the pile is located the jack or ram o. In a further modification the anchorage consists of a frame q, Fig. 10, loaded by weights q<1>, and supporting the vertical tie member r which is braced by struts r<1> and supports the cross-head s. The latter carries pulleys s<1> around which passes tackle guided by pulleys s<2> to winches or winding gear t by means of which pressure is applied to the head of the pile. Suitable gauges or indicators, according to the pressure producing means used, may be provided to indicate the resistance of the pile during driving. In underpinning walls by this method, piles are driven on each side of the wall and beams laid across the heads of the piles to support the wall.

Title: Improvements in or relating to frequency changers using electric discharge devices
IPC: H02M5/00
Filed: 1934-03-19
Abstract: 438,719. Frequency changers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. March 19, 1934, No. 8603. Convention date, March 18, 1933. [Class 38 (ii)] In a frequency changer of the type having cross connected grid controlled discharge devices 1, 2, the devices are provided with auxiliary electrodes 3 by means of which the control of the grids is modified to prevent conduction of one device before the other has ceased to conduct. Each discharge device 1 is controlled by means of an auxiliary valve 4, the grid of which is controlled partly in dependence on the flow of current in the main discharge circuit by means of a current transformer 5 and partly by a circuit responsive to de-ionization in the other discharge device 2 comprising a source of voltage 6 connected in series with a transformer 7 to the auxiliary electrodes 3. When, e.g. the device 2 ceases to conduct and de-ionization of the discharge space takes place, the current in the auxiliary electrode circuit ceases and a voltage impulse is produced in the grid circuit of the valve 4 by the transformer 7, which renders it conductive and thus starts a discharge in the main device 1. To ensure easy starting a relay 8 is provided which ensures that one of the control valves 4 is conductive until the arrangement commences to operate. The neutral point connection shown is stated to cause improvement of the waveform of the output voltage. Specification 388,771 is referred to.

Title: Manufacture from viscose of a substitute for wool
IPC: D01F2/06
Filed: 1936-03-24
Abstract: Artificial fibres suitable as a substitute for wool are obtained by forming continuous filaments of cellulose xanthate from viscose having a viscosity above 200 seconds as measured by the falling ball method, and converting the resulting threads, in continuous form or after being cut to staple length, into cellulose fibres by treatment with an inert liquid heated to a temperature above 70 DEG  C. until decomposition of the cellulose xanthate takes place owing to the high temperature of the liquid. The viscosity is measured by the time taken by a steel ball of 3 mm. diameter to fall a distance of 20 cm. in the viscose at a temperature of 20 DEG  C.  The high viscosity may be obtained by preparing a concentrated viscose, or by avoiding degradation of the cellulose, or by ripening the spinning solution to a high degree.  Preferably, viscose having a salt point below 1 is spun in a spinning funnel with stretching of the filaments.  For the coagulation bath there may be used water, ammonium salts, salts of bases readily displaced by caustic soda, solutions of dissociating salts, alcohols or other organic liquids miscible with water.  The cellulose xanthate threads or bands of fibres may be further stretched before they are converted to cellulose.  In an example, viscose of 3,000 seconds viscosity and salt point less than 0,2 is spun into a solution of sodium sulphate and the threads are treated with ammonium sulphate solution.  The xanthate threads are cut to staple fibre and converted to cellulose by treatment with hot glycerine.  In another example, viscose of 4,000 seconds viscosity is spun into a solution of ammonium sulphate or sodium sulphate with ammonium sulphate, or acetic acid alone or diluted with methanol, and the threads are converted in endless condition by treatment with hot glycol.  Specification 443,971 is referred to.
