Title: Apparatus for supplying pressure liquids
IPC: F04B11/00
Filed: 1962-06-05
Abstract: 1,003,289. Water supplies. O. ECHERLE. June 5, 1962 [June 5, 1961], No. 21747/62. Heading E1X. [Also in Division Fl] In apparatus for dispensing liquids by gaseous pressure, e.g. for domestic water or oil supply, and comprising a main container 2 into which liquid is pumped to compress a volume of air, which then acts to force out the liquid, losses of air are made up by an auxiliary chamber 3, the filling of container 2 is automatically controlled by a pressure-sensitive switch controlling pump 1. Pump 1 delivers to container 2 via chamber 3 which is therefore normally filled with liquid. A discharge valve 6 on chamber 3 is opened by a float 11 in container 2 when the liquid therein rises above a predetermined level, pump 1 having stopped, thereby draining the liquid from chamber 3 which fills with air via a valve 5. When container 2 has emptied, the pump restarts, and the air in chamber 3 is forced into container 2 by the pumped liquid. Air inlet valve 5 is held closed either by the flow of pumped liquid via pipe 10, as shown, or by electromagnetic means actuated by the float, which in this latter case also controls the discharge valve electromagnetically.

Title: Improvements in or relating to flow meters
IPC: G01P5/18
Filed: 1947-08-07
Abstract: 649,030. Automatic control systems for fluid flow. ENGELHARD,Inc.,C. Aug. 7, 1947, No. 21754. Convention date, May 21, 1946. [Class 38 (iv)] [Also in Groups XXIX and XXXVIII] In a flow meter in which the rate of flow is determined using resistance thermometer 58, 59 connected in the arms of a Wheatstone bridge, the rate of flow of the medium (e.g. gasoline) is controlled by a valve 66 controlled by a reversible motor 65 actuated by the out-of-balance of a control galvanometer 62 in the bridge circuit. As shown in Fig. 5, the medium passes through a main conduit with Venturi or orifice 55, and is partially byepassed through a conduit 56 containing a thermallyinsulated heat-conductive section heated by a coil 57 and carrying a resistance thermometer coil 58. Thermo-constant resistors 60, 61 form the remaining arms of the bridge, while the watts input to the coil 57 is controlled by a variable rheostat 63 and indicated on a wattmeter 64 preferably calibrated to give the rate of flow in lb./hr., gall./hr., &c. The desired rate of flow is pre-set by means of the current regulator 63, the bridge being balanced; a change in rate of flow unbalances the bridge whereupon the control galvanometer 62 operates the motor 65 to increase or decrease the valve opening 66 to adjust the flow to the pre-set rate.

Filed: 1924-09-24
Abstract: 248,018. Brunton, J. L., and Brunton Bros., Ltd. Sept. 24, 1924. Operating doors hydraulically and by toothed-gear mechanism and chain and cord arrangements. -Watertight doors of ships are operated by a cylinder to which pressure fluid (e.g. boiler-feed water) is supplied by a valve controlled through a Bowden cable device from either of two positions (e.g. a local and distant station). Fluid pressure is supplied through a valve casing 6 to pipes 7 or 8 of the cylinder 4, which contains a piston for moving a sliding door 1. Local hand-operated gear 30 - - 34 is also provided. The differential valve piston 10 has a spindle 11 connected ta a lever 12 movable about the end of a link 13, and this lever is connected by a link 29 with an abutment 28. Between this abutment and the fixed abutment 27 is the outer casing 26 of a Bowden mechanism, the inner inextensible cable 24 leading to a distant control, such as on the bridge of the ship, and at its lower end to a handle 25, convenientlv located near the door 1. When the handle 25 and the distant control are secured by means of a bracket 25<1>, so that the piston is in the lower position as shown, pressure fluid from the pipe 5 passes through a passage (not shown) to the upper part of the valve casing and thence through the port 15 and pipe 7 to maintain the door in the raised position, the pipe 8 being put to exhaust through the port 19 and pipe 9. When the cable 24 is released from the bracket 25<1> or from the distant control, the casing 26 is free to flex and the piston 10 rises owing to the greater pressure exerted on its lower end. Pressure fluid then passes to the upper end of the piston 4 and the door closes. The door may be again opened by pulling the cable 24. The Bcwden cable operating mechanism may be of the kind described in Specification 205,844, [Class 80 (iii) Link-work &c.], and the piston 10 is preferably supplied with packing.
