Title: Improvements in domestic refrigerators
IPC: F25B17/00
Filed: 1921-06-04
Abstract: 168,585. Rumpler, E. Sept. 1, 1920, [Convention, date]. Refrigerating, absorption machines and processes for; refrigerators, domestic and Like.-In an ammonia apparatus working on the reversing system and adapted for use with a domestic refrigerator a pivoted or flexible pipe mounted in the absorber-generator is arranged to be automatically raised above or immersed in the water in the absorber-generator during the heating or absorption period respectively, the 'heating and circulation of the cooling water being also automatically controlled. As shown, the absorbergener,ator k is heated by an electric heating- element p and is provided with an oscillating pipe a which during the heating period occupies the position shown in full lines, being attracted by an electromagnet m so that the ammonia gas given off passes through a pipe l, and condenser c into a collecting vessel S and evaporator coil v, the vessel S and coil v being arranged in an insulated compartment u in a refrigerating- chamber r. When the temperature reaches a certain value, a thermal switch t opens the circuit of the heating-element p and electromagnet m through the medium of a relay and causes the end of the pipe a to fall into the liquid. At the same time and a similar mann,er, a damper in the cooling water system is operated to divert the water from the condenser c to theabsorber-genjerator k, and a louver frame in a wall of the compartment u is operated to open the louvers during the evaporation and re-absorption period. When the temperature reaches a low limit, the thermal switch becomes operative to close the circuit of the element p and magnet m and the process is repeated. A cell or mould e may be arranged in the collecting-vessel S for ice-making. The absorber-generator may be heated by means of gas or the like, in which case electric means are employed to operate the controlling-elements.

Title: Improvements in electric timing circuits
IPC: H03K17/288
Filed: 1940-11-04
Abstract: 542,107. Switching systems for electric welding. BRITISH THOMSON-HOUSTON CO., Ltd., and HIGGINS, B. G. Nov. 4, 1940, No. 16047. Addition to 463,561. [Class 38 (iv)]  The period of application of supply to an electric weld is determined, automatically, by the rate of discharge of the condenser 10 which is normally on charge from the secondary 7 through the rectifier 11, is disconnected therefrom when the switches 18, 19 are moved over by manuallycontrolled energization of their operating coil 16, and thus connected to the grid of the discharge device 2 the anode current of which is adapted to energize the coil 3 and close the welding supply contact. The condenser makes the grid positive and the valve 2 conductive with consequent closure of the contactor; the slow discharge of the condenser allows the negative bias on the grid to re-establish control after a time and thus render the valve non-conductive again and break the energizing circuits of the welding contactor. As the charging of the condenser takes place when there is no welding load on the system, this charging is unaffected by variations of voltage and accurate timing is ensured.

Patent GB-652321-A (GB)
Title: Improvements in apparatus for controlling the fuel supply to engines
IPC: F02C7/22
Filed: 1948-06-15
Abstract: 652,321. Gas turbine plant. BENDIX AVIATION CORPORATION. June 15,1948, No. 16132 Convention date, June 26, 1947. [Class 110(iii)] [Also in Groups XXIX and XXXIV] Apparatus for controlling the fuel supply line to a gas turbine comprises a throttling valve having end portions or pistons 44, 45 of different effective area supplied with fluid under pressure through conduit means 50, 52 having a restriction 53 in the part between the portions or pistons 44, 45 and a drain opening 57 adjacent one end portion under the control of a pilot valve 39 actuated in dependence on an engine operating condition. As shown, a gas turbine engine comprises a turbine 3 driving through a shaft 2 a compressor 1 and an alternator 9. The valve 41 controls the fuel supply from a combined oil and fuel pump 15 through conduits 8 to burner nozzles 7 in combustion chambers supplied with air from the compressor 1. The fuel regulating apparatus 14, Fig. 1, is shown in detail in Fig. 2. The pump 15 comprises opposed fuel pump pistons 17 and opposed oil pump pistons 18 all driven from an eccentric 19 in turn driven from the engine through a shaft 16. The pistons 18 constantly supply a chamber 51 through the conduit 50. The chamber 51 communicates with a further chamber 56 through a conduit 52, a chamber 54 and a passage 55. The pilot valve 39 when open causes the pressure in the chamber 54 and hence the chamber 56 to diminish so that the throttling valve 41 tends to close valve ports 43, 47 and open byepass ports 48. The valve 39 is biassed against a lever 33 by a spring 40. The lever 33 is controlled at one end. by a centrifugal governor 30 driven through a shaft 31 from the engine and at the other end by a solenoid 37 the core 35 of which supports a fulcrum pin 34. The solenoid 37 is connected across a shunt resistance 66 in circuit with one of the leads 11, 12 between the exciter 10 and the field of the alternator 9. The speed setting of the governor 30 is thus modified in accordance with the electrical load applied to the alternator through leads'13. The apparatus thus provides "speed droop" as the load increases. A pin 75 actuated by a spring-loaded bellows 70 exposed internally to the fuel pressure in the nozzle lines 8 and externally to the compressor outlet pressure through a pipe 73, operates on the lever 33 and hence controls the valve 41 to prevent the air-to-fuel ratio from falling below a predetermined safe minimum value. If the engine over speeds, a centrifugal pump 75a driven from the engine and having radial channels 76 creates sufficient pressure difference across a spring-loaded diaphragm 79 to withdraw a trip pin 84 from beneath a spring-loaded plunger 85 having a manually operable resetting knob 87. On release, ,the plunger 85 cuts off the pressure conduit 50 and positively moves the valve 41 down to shunt off the fuel supply. The plunger has a stem 89 engaging a bore 90 and having a drain passage 91.

Title: Manufacture of solid polymers of formaldehyde
IPC: C08G2/08
Filed: 1925-06-26
Abstract: 260,908. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 26, 1926. Formaldehyde and polymers thereof. - Solid polymers of formaldehyde are obtained by removing water from gas mixtures containing formaldehyde and water vapour and separating the solid product from the gases. Preferably the water is removed by rapid cooling, the resulting aqueous formaldehyde solution, from which paraformaldehyde may separate, being rapidly removed so that part of the formaldehyde is carried away with the gases to be separated therefrom as a solid product. The gas mixture to be treated may be obtained by the catalytic oxidation of methanol, preferably anhydrous methanol being used and the temperature of the catalyst is controlled by admixture of inert gases, such as the residual gases of the process; the inert gas may, however, be water vapour, or dilute methanol may be used, when only a minor part of the formaldehyde is to be prepared in the solid state. According to an example, methanol of 80 per cent strength is catalytically oxidized to formaldehyde and the reaction products are introduced from below into an inclined cooler wherein they are rapidly cooled. The condensate is removed from the cooler by an overflow and the uncondensed portion withdrawn from the upper end of the cooler is introduced into chambers wherein the solid product separates. The product may be separated by other suitable methods such as filtering or electric precipitation. According to another example, the gas mixture resulting from the catalyticoxidation of anhydrous methanol is cooled by contact with a strongly cooled formaldehyde solution. for example by passing the mixture through capillary tubes in an oblique direction on to the surface of the solution, and the uncondensed residue is suitably treated to separate the solid product.

Title: Improvements relating to Railway Signalling.
IPC: B61L1/18
Filed: 1917-11-07
Abstract: 118,513. McKenzie, Holland, & Westinghouse Power Signal Co., (Union Switch & Signal Co.). Nov. 7, 1917. Electrical systems, automatic. - Signalling-current is supplied to the track rails and track relays through a condenser and an inductance in series, the inductance having an iron core which is magnetically saturated by t h e normal current in the track rails. The condenser K may be arranged directly in the supply circuit or in the secondary circuit of a transformer M as shown in Fig. 3. The arrangement is such as to provide for a constant current in the track relay although the resistance between the track rails 1, 1<a> varies from time to time, since the impedance of the inductance coil I decreases as the current through it increases.
