Title: Improvements relating to the delivering of measured quantities of pressurised liquids
Inventor: PORTER THOMAS
IPC: B67D1/10
Filed: 1962-11-30
Abstract: 1,067,865. Dispensing liquids. PORTERLANCASTRIAN Ltd. Feb. 13, 1964 [Nov. 30, 1962; Jan. 4, 1963; April 29, 1963], Nos. 45281/62, 463/63 and 16692/63. Heading A4T. [Also in Division F1] Apparatus for delivery in measured quantities of pressurized liquids such as draught beer comprises a rigid container 1, the walls of which are separable at flanges 2 for cleaning purposes and which contains a diaphragm 3, the driven side of the diaphragm having an inlet pipe 7 from a storage vessel (not shown) and the driving side having an inlet 8 from a source of pressure gas such as compressed air or nitrogen, this conduit including a threeway valve 9. The device also has a discharge conduit 10 leading to a normally closed outlet 11. On operation of the control means valve 9 is moved to admit gas from the conduit 8 to chamber 1 and valve 12 of outlet 11 is opened. The diaphragm 3 is deflected by the gas pressure and beer is expelled through outlet 11. Non-return valves 13a, 13b are provided in conduits 7, 10. Conduit 8 has an adjustable needle valve 8a by which the rate of flow into container 1 can be varied and when the diaphragm 3 is fully deflected pressure builds up and eventually operates a normally closed pressure-sensitive switch 14 to break the circuit, close outlet valve 12, return valve 9 to a position which exhausts the driving side of container 1 and thus allows the pressure from the storage tank to refill the other side of the chamber until contacts 6 on the diaphragm co-operate with contacts 4 on the container wall to allow discharge to be repeated. In a modification (not shown) the centre of the diaphragm is attached to a piston, electromagnetically or fluid operated. Two devices may be coupled so that one diaphragm expels while the other is drawing in or two separate pumps may operate in synchronism, one expelling while the other is being filled. In another modification the contacts 4, 6 and switch 14 are replaced by an arrangement including a spindle (22) attached to the diaphragm 3 and having two adjustable collars (23, 24) in the path of which are limit switches (25, 26).

Abstract: 919,514. Heating steam boilers by hot gases; superheaters; tubular heat - exchangers. SULZER FRERES S.A. Dec. 18, 1961 [Dec. 30, 1960], No. 45305/61. Classes 64 (3), 123 (2) and 123 (3). A heat-exchanger which may be used as a vapour generator comprises groups of identical numbers of helically wound tubes all of'the same pitch but disposed at varying radii around a common central axis. Tubes of longer tube length are connected in series with tubes of shorter tube length in a different group so that the working medium flows through a number of paths of equal total tube length connected in parallel. The heating medium which may be the coolant gas from a nuclear reactor flows outside the tubes in a direction parallel to said axis. In the embodiment shown the working medium enters the four tube coils of tube groups 10, 9 and 8 through inlet headers 11. These coils are connected by pipes 13, 14 and 15 to coils in groups 5, 6 and 7, respectively, the working medium being discharged through outlet headers 12. A guide element 16 serves to ensure uniform axial flow of the heating medium over the tubes. In another embodiment (Fig. 3, not shown) the tubes in each group form coils of differing radii and the groups are placed successively to one another in the axial direction.

Abstract: 1,190,289. Vehicle signalling arrangements. ESSEX INTERNATIONAL Inc. 24 Sept., 1968, No. 45317/68. Heading G4Q. [Also in Division H1] A push button switch 38, Fig. 2, attached to the steering column 3 of a motor vehicle and arranged for emergency connection of all indicator lamps 5-8, Fig. 6, to a flasher unit 59 through contacts 41-44 and 45 is latched on by full depression of the push button 52 but is automatically released by movement of a cam 29 on the steering shaft 1, whereby the vehicle cannot be driven with all indicator lights flashing since a small movement of the shaft 1 will release the latch. The contacts 41-45 are engaged by a single leaf bridging contact spring 40 mounted on a carrier 34 which is moved by a wedge cam face 56 on slider 49 carrying the push-button 52. On full depression of the button 52 a flat face 55 latches under end face 57 of the contact carrier 34. The latch is automatically released by push rod 72 actuated by the steering shaft cam 29 and having a bevelled end 75 engaging the wedge cam face 56 to cause a small return movement of the slider 49 sufficient to disengage the latched faces 55, 57. Push rod 75 is actuated from the cam 29 on the steering shaft 1 through a spring-loaded plunger 66 moving slider 61 having a bevelled end face 77 co-operating with a bevelled end 76 of the push rod 73. The switch 10, Fig. 2, is a turn-indicator switch, which is incompletely described in the Specification.

Title: Power operated actuator
IPC: H02K7/06
Filed: 1967-10-05
Abstract: 1,201,634. Screw-and-nut actuators. NEW YORK AIR BRAKE CO. 5 Oct., 1967 [10 Oct., 1966], No. 45596/67. Heading B8J. [Also in Divisions F2 and H2] An actuator for operating a valve having a duct 11 with a valve plug 10 comprises a first screw member 15 arranged for non-rotative axial movement and connected to the plug 10 by a valve stem 12 and collar 16 with a set screw 17. The position of member 15 is indicated by an arrow 19 movable along a fixed indicator 20. A second screw member 25 threadedly engages the first screw member 15 and is rotated by a motor 28 through a gear 26 fixed on the second screw member 25. The member 25 has a nut 45 fixed to it by a set screw 46 and this provides an abutment shoulder 47 on which is a thrust bearing 48 engaging a collar 49 on non-threaded portion 38 of the member 25. A collar 37 is also on non- threaded portion 38 and is spaced from lower portion 41 of the gear 26 by a thrust bearing 40, a snap ring 42 ensuring no play between the gear 26 and collar 37. The second screw member 25 is generally axially fixed but is subject to slight axial movement being loaded by resilient means consisting of concave and convex washers 50 between the collars 37, 49 which collars are held against rotation and tend to be spread apart by the washers 50. A spindle 60 extends from the upper end of the member 25 and has a radial disc 61 projecting between normally closed switches 62, 63 with plungers 64, 65. To open the valve, switch 75, Fig. 2, is thrown downwardly so that the motor 28 rotates so as to move member 15 upwardly. At the limit of this movement there is a reaction causing compression of the washers 50 by the member 25 being tended to move downwards and thus the motor 28 is switched off by operation of the switch 63. Conversely, when the valve is to be closed, the switch 75 is thrown upwardly and, when the plug 10 engages valve seat 23 there is a movement of the member 25 upwardly so as to open the switch 62 and switch off the motor 28. The motor 28 will also be stopped if any obstruction interferes with the movement of the valve in any intermediate position. In case the actuator is used otherwise than for control of a valve, abutment 72 on member 15 co-operates with stops 70, 71 to define the end positions.

[Also in Division F2] An anesthesia machine, shown as a flow diagram in Fig. 1, comprises an oxygen source 1, a supply line 5 leading from the source, to a by-pass valve 8 comprising a body 10 (Fig. 2) with a through bore 21 and a partial bore 23 transverse to the through bore and linking the through bore with an exterior surface of the valve, the line 5 including a pressure regulator, a needle valve 3 and a flowmeter 4 to measure the oxygen flow rate, a first supply outlet line 32 from the by-pass valve having three sub branches each of which includes a needle valve 35 and a flow meter 36 and leads to a vaporiser 37 which includes a liquid anesthetic agent, a heater and thermostat and means for bubbling oxygen through the liquid, an outlet from the vaporiser joining a second outlet line 7 from the by-pass valve and entering an altitude compensator valve 83. The vaporisers are controlled by shut-off valve assemblies which may be linked together by an interlock to preclude the use of more than one vaporised agent at a given time. The shut off valve (see Fig. 4) includes a body portion 54 with inlet openings 64 and outlet openings 65, a camshaft 55, a pair of thrust pins 58 and balls 59. Balls 59 are positioned in bores 66 and spring biased to maintain them against thrust pin noses 68. The balls close openings 69 when thrust pins 58 are located in grooves 60. When rotated, every quarter turn the camshaft cams the thrust pins to force balls 59 from sealing engagement with openings 69 and thus opens the valve. The altitude compensator valve (see Fig. 5) contains a diaphram 87 held in place at 88 by pressure contact between lower part of body portion 85 and upper part of cap 89, caused by clamp 94. A hollow piston 96 is connected to the diaphram, and a compression spring 100 is received within the piston. Gas enters the valve through inlet elbow 84, displaces diaphragm 87 and leaves through opening 92. Pressure on the diaphragm 87 due to the piston 96 may be varied by means of an adjusting screw 102 so that the pressure of the gas flowing through the valve may be reduced by a required amount.
