Title: Improvements in or relating to pumping apparatus
IPC: F04D15/00
Filed: 1935-11-26
Abstract: 471,047. Water supply. CLAGOOD CO., Ltd., and GOODMAN, W. R. Nov. 26, 1935, No. 32782. [Class 68 (i)] [Also in Group XXVIII] A system for the automatic supply of liquid comprises a main reservoir 1 and a supplementary reservoir 6 having float or pressure means 33 for operating a switch 37 in the circuit of a motor 3 which drives a supply pump 2. An appliance 10 controlling the connections between the pump 2, the reservoir 6 and the points of consumption 8, contains a main valve 14, having a through passage which is controlled by an oppositely-opening supplementary valve 26. In operation, when the tap 8 is opened, fluid is supplied from the reservoir 6 past the valve 26 until the level or pressure in the reservoir 6 falls sufficiently to start the motor 3. Thereafter the pump 2 supplies the point 8 and the valve 26 closes. When the tap 8 is closed the pressure opens the valve 14 against the action of a spring 19 and the reservoir 6 is replenished. The tension of the spring 19 is adjustable by means of a renewed sleeve 16.

Title: Improvements in or relating to a servo-control for a fluid-pump or motor
IPC: F15B9/08
Filed: 1955-11-18
Abstract: 812,927. Fluid-pressure servomotor control systems. VICKERS Inc. Nov. 18, 1955 [Nov. 19, 1954], No. 33011/55. Class 135. A servo control for a fluid pump or motor device having a control member for varying the displacement of the device, e.g. the swash plate of a pump, comprises fluid motor means continuously biasing the control member in one direction, e.g. the piston 44 constantly loaded by outlet pressure from auxiliary pump 14 ; second fluid motor means 46, 48 acting in opposition to the biasing means for shifting the control member in another direction, valve means 16 for controlling the second motor having means 128 for shifting a first valve part 92 to initiate displacement controlling movement of the control member, and resilient means 106, 126 continuously biasing a second valve part 80 and a linkage 110, 112 to the control member for effecting a follow-up action. In a power transmission having a swash plate pump driving a fluid motor, the pump shaft directly drives an auxiliary vane-type pump 14, the output from which acts on piston 44 to continuously bias the swash plate in an anticlockwise direction, and is also led to a peripheral chamber 84 in a valve sleeve 80 and to a space 98 between two lands on a piston valve sliding within the sleeve. Movement of the piston valve to the left allows pressure in the space 98 to act on the pistons 46, 48 which. being of greater area than the piston 44, will move the swash plate in a clockwise direction. An arm on the swash plate acts on a rack engaging the gear 112 which then moves the rack 110 and sleeve 80 against the spring 106 to re-centre the sleeve with respect to the piston valve and cut-off pressure from the pistons 46, 48. Exhaust from these pistons passes via an axial passage 100 through the piston valve.

Title: Improvements in the manufacture of chlorine dioxide
Inventor: WINFIELD JOHN DONALD
IPC: C01B11/02
Filed: 1964-08-13
Abstract: ClO2 and Cl2 are produced by continuously adding an alkali metal chlorate and chloride, and H2SO4 to a generator, and maintaining an acidity of 1-2.4 M, a temperature above 30 DEG  C., and a partial pressure of water such as to ensure crystallization of anhydrous alkali metal sulphate.  Liquid effluent may be withdrawn and recycled either directly or via a crystalliser.  The alkali metal may be Na, K, or Li.  The chlorate and chloride may be added dry or as solutions, separately or together, in a ratio of 1:1 to 1:6 respectively. H2SO4 used may be above 100%.  The partial pressure of water may be maintained in the generator by means of a water jet eductor (which produces a partial vacuum and also dissolves the ClO2 and Cl2) or by using a stream of inert gas, e.g. air or N2.  If a crystallizer is used, the partial pressure is maintained there by the same methods, and the ClO2 and CL2 are removed from the generator by means of a vacuum or stripping gas.  The product gases may be scrubbed by the incoming chlorate and chloride solutions to remove HCl.

Title: Process and regulating installation for concentrating hydrochloric acid from gases containing hydrogen chloride
IPC: C01B7/01
Filed: 1961-09-20
Abstract: A continuous process for preparing concentrated hydrochloric acid comprising contacting a gaseous mixture containing hydrogen chloride in countercurrent with water in an adiabatic absorption tower, with drawing hydrochloric acid from the absorption tower and treating a portion thereof in a desorption apparatus so as to generate dilute hydrochloric acid and a gaseous effluent containing a major proportion of hydrogen chloride, and contacting said gaseous effluent with the remainder of the hydrochloric acid withdrawn from the tower in an absorption apparatus with simultaneous cooling so as to form concentrated hydrochloric acid. In Fig. 1 the waste gases enter the packed tower 2 through inlet 1. Absorption water is added through conduit 3, and HCl of 32% strength and at 78 DEG  C. is discharged to sump 4. Part of this acid is conveyed by pump 5 into an evaporator 6 where it is decomposed into a vapour containing 85% HCl and an acid of 30% HCl. The evaporator consists of a reservoir 7 for the acid, a falling film heat exchanger 8 and a packed hollow cylinder 9. The vapour containing 85% HCl flows through a conduit 12 into exchanger 14 where the vapours are absorbed with simultaneous cooling by mea of residual HCl of 32% to form acid of 38% which collects in reservoir 16. The excess HCl vapours are returned via 15 into the tower at 17 about 500 mm. above the lower end of the <PICT:0956608/C1/1> column 2, which distance corresponds to a theoretical tray. The rate of supply of water to the adiabatic absorption tower 2 may be controlled in correspondence with variation in the rate of supply of hydrogen chloride in the gaseous mixture and concentration of acid discharged from the tower 2, and the rate of passage of cooling liquid through the absorption apparatus may be varied in inverse correspondence with variation in concentration of the acid discharged therefrom.

Abstract: 942, 694. Automatic temperature control systems for motor vehicles. M. BEHR,[trading as SUDDEUTSCHE KUHLERFABRIK JULIUS FR. BEHR. ]. Sept. 20,1961 [Sept. 21, 1960], No. 33705/61. Heading G3R. [Also in Division F4] An air conditioning installation of the kind comprising both heating and refrigerating units, particularly those for use in motor vehicles is controlled to maintain a predetermined temperature by continuous switching on and off of the heating or cooling units. A selector switch 9 enables heating or cooling to be selected together with the desired temperature. Temperature detectors 4, 6 are placed at the outlets of the heating and cooling units 1, 2 respectively and together with resistors 24, 25-set by the selector 9-form a bridge circuit which by way of a supply voltage compensator 27, a multivibrator 29, and an amplifier 30 controls the "mark-space" ratio of an electronic switch 31 which in turn controls the operation of the heating and cooling units 1, 2. If heating has been selected by the selector 9, an electromagnetic valve 11 in the inlet to the heating unit 1 is energized, fan 12 is started and flap 15 in the fresh air inlet is opened. Thus the valve 11 is opened and closed intermittently by the operation of the switch 31, which comprises transistors, until the selected temperature is reached. A thermostat 18 is included to preclude the operation if the engine cooling water has not attained a given value. If cooling is selected an electromagnetic coupling 19 on the refrigerator 2 is energized, fan 21 is started and flap 17 in the re-circulating circuit is opened. In this case the coupling 19 is intermittently energized until the selected temperature is reached. Alternatively the fans 12, 21 only may be energized to provide ventilation. The electromagnetic devices may be operated by hydraulic or pneumatic means. In the case of an air cooled engine the heated air may be used in the heating unit. The speeds of the fans 12, 21 may be manually varied.
