Title: Improvements in or relating to electrical control apparatus
IPC: G05F1/32
Filed: 1958-03-19
Abstract: 835,509. Automatic voltage control systems. WESTINGHOUSE ELECTRIC CORPORATION. , March 19, 1958 [March 22, 1957], No. 8777/58. Class 38 (4). In an automatic tap-changer or induction regulator, the con- .trolling motor is energized by a trigger pair of magnetic amplifiers in accordance with output voltage error. The output of a potential transformer 16 is added to the output of a line drop compensator 20 and is applied directly to a rectifier 32 and through a saturable transformer 61 to a rectifier 34. The saturable transformer maintains the output of rectifier 34 substantially constant to provide a reference voltage opposing the output of rectifier 32 and so a D.C. error voltage of reversible polarity is obtained proportional to deviations in the output voltage of the transformer 18. The error voltage is applied to the control windings CW1 and CW2 of a bistable pair of autoself-excited magnetic amplifiers MA3, MA4 so that for a given polarity it will opposie or aid respectively the standing bias applied from a D.C. source 136 to windings BW3, BW4. The amplifiers are biased beyond cut-off by the standing bias, and the magnitude of the bias is adjustable to determine the bandwidth of the control system. If the error voltage exceeds the bias, the appropriate amplifier conducts, and becomes fully conducting due to a positive feedback winding PF3 or PF4 connected in parallel with the output which is derived from either rectifier 132 or 134. The outputs of the amplifiers MA3, MA4 control a pair of magnetic amplifiers MA1, MA2 operating as in Specification 808,924 to energize relays 41, 43 after a predetermined time delay. The relays 41, 43 control the reversible tap change motor 47. If the tapped transformer 18 is replaced by an induction regulator, the time-delay amplifiers are omitted. In a modification, Fig. 2 (not shown), the amplifiers MA3, MA4 are coupled to the time-delay amplifiers MA1, MA2 by step-up transformers and rectifiers.

Patent GB-495026-A (GB)
Title: Improvements in the process of removing ammonia from gases
IPC: C01C1/12
Filed: 1937-04-03
Abstract: Ammonia is removed from gases by bringing the gas containing ammonia into contact with microporous hydrophilic adsorbents which contain added water.  The exhausted mass may be regenerated by a treatment with moist or moistened gases or with steam.  The water may contain neutral salts such as ammonium nitrate or calcium chloride.  The adsorbent may be silica gel, e.g. wide pored silica gel as described in Specification 263,198, [Class 1 (ii)], or active alumina, e.g. as described in U.S.A.  Specification 1,760,289.  The adsorption process may be conducted at pressures of 20-200 atmospheres.  The process may be conducted by passing the ammonia containing gas through two adsorbent-container systems which are alternately in operation and regeneration, each system comprising at least one container charged with wide-pored silica gel for the removal of the ammonia and at least one container charged with narrow-pored silica gel, e.g. as described in Specification 263,199, [Class 1 (ii)], for drying the gas, the latter first flowing through the wide-pored gel and then through the narrow-pored gel.  The wide-pored gel may be replaced by active alumina and the narrow-pored gel may be replaced by superimposed layers of wide-pored and narrow-pored silica gel or by superimposed layers of active alumina and narrow-pored silica gel. Mixtures of carbon monoxide and hydrogen containing ammonia may be treated by the process.  In treating circulating gases from the synthesis of ammonia in the above series of containers, the major proportion of ammonia is preferably initially separated by other methods, e.g. by cooling, and washing with water and/or contact with dry adsorbents at low temperature.  The regeneration may be effected by a dry gas which first passes through that part of the system which dries the initial gases and thus becomes moist and expels the ammonia from the moist hydrophilic adsorbent. Instead of an independent supply of dry gas, the dry ammonia-free gas obtained in the process may be divided into two parts, the larger part being returned to the ammonia synthesis and the smaller part being employed for the regeneration.  The process may also be conducted in a tower charged in the lower third with flints or Raschig-rings of stoneware or carborundum serving to store heat, in the central third with coke and in the upper third with wide-pored silica gel, the gas to be freed from ammonia passing upwards through the moistened porous mass and the steam for regeneration passing downwards.  The porous mass may be freed from superficially adherent water by means of upward flowing cold air or nitrogen.  The Provisional Specification describes the employment of liquid acids instead of water.

Title: Improvements in or relating to washing machines
IPC: A47L15/16
Filed: 1946-03-27
Abstract: 620,758. Domestic washing-machines. NANSON, D. J. March 27, 1946, No. 9525. [Class 138 (ii)] [Also in Group XXIII] A washing-machine for washing crockery and the like and applicable for washing fabrics comprises a boiler 15, Fig. 1, which supplies hot water through jets 33 to a washing chamber 14, a control device 22 which shuts off the supply of heat to the boiler before all the water has evaporated, and a reservoir 13 from which fresh water may be drawn through the jets into the chamber 14 to rinse the articles in consequence of reduction in pressure in the boiler. The boiler 15 is heated by an immersion heater 16, supplies water to the chamber 14 through pipes 21 and 26, jets 33 and perforated pipes 35 which form racks for supporting the articles to be washed. The boiler is filled through a funnel 19, cock 20 and feed pipe 18, a drain cock and an air release cock being provided on the boiler. When the level of the water in the boiler 15 falls below the bottom of the pipe 21, the supply of heat is cut off by a device 22 in the pipe 26. The device 22 may comprise a float 45, Fig. 5, which falls owing to the absence of water in the pipe 26 and opens electrical contacts 48 to shut off the supply to the heater 16 or alternatively the device 22 may comprise a diaphragm 52, Fig. 6, which carries a contact 53 which completes a circuit which shuts off the supply through a contact 48 by upward distortion of the diaphragm 52 due to the heating effect of the steam.. Rinsing water in the reservoir 13 is preheated by an open-ended pipe 38 leading from the chamber 14 through a non-return valve 39 and is drawn into the chamber 14 through a non-return valve 29 due to a reduction of pressure in the chamber 14 transmitted from the boiler 16 through a non- return valve 23. The reduction of pressure in the boiler 16 is caused through condensation of the water vapour after the supply of heat has been switched off. The boiler may be alternatively heated by gas, in which case the control device controls mechanical means for shutting off the supply of gas. The feed water may be pre-mixed with a detergent, and for the hot treatment of fabrics a non-aqueous solution may be employed.

Title: Means for Controlling the Supply of Liquid Fuel to Internal Combustion Engines.
Inventor: MURTAGH FRANK
IPC: F02D1/00
Filed: 1916-07-08
Abstract: 107,435. Murtagh, F. July 8, 1916. Regulating.-The pumps supplying petrol or other liquid fuel to an engine are actuated by variable-throw cams which are adjusted automatically through the medium of a piston or diaphragm which constantly tends to be moved in one direction by a spring and in the opposite direction by the difference between the pressure of the atmosphere, to which one side of the piston &c. is exposed, and the suction in the induction pipe, to which the other side of the piston &c. is exposed. The piston rods B of the pumps A are pressed by springs G against the cams F, F<1> which are slidably mounted on a shaft E driven by the engine. A rod K, Fig. 2, connects the cams F, F<1> to a piston H slidable within a cylinder J which has an opening j communicating with the atmosphere and another opening j<1> leading to the induction pipe. Any reduction of pressure in the induction pipe will cause the piston H to move to the right, and the corresponding movement of the cams will cause the supply of fuel to be increased. Conversely an increase of pressure in the induction pipe will cause a reduction in the fuel supply. When used on aircraft, the supply of fuel will vary also with the rarefaction of the air. In a modification, the rod K is connected to a diaphragm which is connected to the right hand wall of the cylinder J by a flexible envelope. Either of the automatic devices described may be coupled to a rod P connected to the throttle as shown in Fig 4 and worked by hand.
