Title: Improvements relating to means for testing gas meters
IPC: G01F25/00
Filed: 1954-02-05
Abstract: 752,231. Testing gas meters. NORTH WESTERN GAS BOARD, and MOTTRAM, W. Feb. 22, 1955 [Feb. 5, 1954], No. 3472/54. Class 54. Apparatus for testing a gas meter comprises means for connecting a meter for testing, a fan or blower 2 for supplying air, a test meter 34 for measuring the volume of air supplied in order to test the registration of the meter, a gauge or manometer 29 for connection across the meter to test for oscillation or absorption of pressure, a pressure gauge 28 for testing the meter for leakage, and valves for effecting the appropriate connections for various tests. The apparatus includes electric and pneumatic circuits, shown in Figs. 1 and 2, respectively, the former being supplied from a plug 1 and having a connection to the blower 2. Leakage test.-The inlet and outlet of the meter are connected to adapters 26, 27, and a switch 5 is closed to open valve 10 and light indicator lamp 16, the meter outlet being connected to a valve 11 which remains closed. When the reading on a gauge 28 has risen to about 12 inches water gauge, the valve 10 is closed and any leakage is indicated by a drop in pressure on the gauge 28. The valve 11, controlled by a switch 6, releases the air through a cock 30 and an adjustable orifice 31 when the test is complete. Pressure - oscillation test. Air is passed through the meter from a governor 32 and a valve 13 controlled by a switch 7 while the inclined tube manometer 29 is observed. An indicator lamp 18 is also operated by the switch 7. Registration test.-A switch 8 is closed to light an indicator lamp 17 and to open valves 11, 12 and 14 so that air controlled by a governor 33 at a pressure of 2 inches water gauge flows through the meter under test, and through the meter 34 which indicates cubic feet passed and the registration error of the meter under test. The adjustable orifice 31 enables the registration to be tested at normal and small flow rates. Prepayment-mechanism test.-The inlet and outlet of the meter are transferred to adapters 23, 24 and a valve 9 opened by closing a switch 4 to allow air to pass through an adjustable orifice 21 and a pressure gauge 22 to the inlet of the meter. A coin is inserted in the meter which passes air until the prepayment valve closes when a pressure operated switch 19 on the outlet side of the meter closes to light an indicator lamp 15. The meter dial shows whether the prepayment mechanism is working correctly. The equipment may be mounted on a panel and installed in a workshop vehicle, the power unit of which supplies the electric circuit.

Filed: 1924-02-12
Abstract: 222,748. Stehli, H. J. Feb. 12, 1924. Open pan roasting and sintering apparatus.- In apparatus for sintering or otherwise treating ores of the type in which receptacles containing the ignited ore are moved over a suction box whereby air is drawn through the ore, flexible means, controlled by the pressure of the air in the wind box, are provided for producing air-tight joints between the suction box and the receptacles. In the form shown, wheels 5 on an endless chain of receptacles 2 move on rails 7, and an air-tight joint between the side walls 2<a> of the receptacles 2 and the wall of the suction box 14 is attained bv means of a strip 16 secured to a projecting edge 14<a> of the box. In other forms, strips secured to the rails engage with laterally projecting ribs on the receptacles 2; or strips secured to and travelling with the receptacles may move over smooth surfaces on the rails; in the latter case the successive lengths of strip overlap at the adjacent ends of the receptacles. Similar air-tight means are also provided in connection with the dead plates at the opposite ends of the suction box. The strips may be made of hemp or asbestos cloth preferably impregnated with lubricant.

Abstract: 510,789. Fluid-pressure servomotor-control systems. ASKANIA-WERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU. Feb. 5, 1938, No. 3721. Convention date, Feb. 5, 1937. [Class 135] [Also in Group XX] Means for increasing the rate of precession upon starting up the gyroscope are automatically put out of operation when the gyroscope has reached alignment with the magnetic element. As shown in Fig. 1, the rotor 1 spins on a horizontal axis 3 in a frame 4 pivoting on a horizontal axis 11-11 in a vertical gimbal ring 12. The frame 4 carries a nozzle 5 for driving the rotor and a magnetic needle which pivots in vertical bearings 33 and drives a cam disc 8 adapted to control differentially the supply of air from nozzles 18 to orifices 19 leading through channels 20 to two diaphragm housings 6. The latter form a relay which operates, through a link 24, pivoted shutters 27, Fig. 5. The shutters 27 control air jets 26 for applying.torques to precess the gyroscope into alignment with the magnetic needle 7. Upon starting up the apparatus air pressure is also applied through the pipe 30 to a cylinder 10, Fig. 4, carried by the frame 4 and causes a loosely fitting piston 9 to be raised against the action of a spring 29 so that the air under pressure may pass through a pipe 31 to additional air jet orifices 28, Fig. 5, which cause a quick precession of the gyroscope. The piston 9 is provided with a notch 35 engaged by a spring latch 37 which holds the piston in its raised position until a projection 39 on the shutter 27 engages an extension of the latch 37. This occurs when the shutter reaches its central position, i.e., when the gyroscope.is in alignment with the magnetic needle 7, the latch 37 being then withdrawn and the air under pressure, which has leaked past the piston 9 permits the spring to restore the piston 9 to its initial position and cut off the supply of air to the additional orifices 28. Pendulous shutters are provided for maintaining the rotor axis horizontal as described in Specification 408,121, [Group XX]. Specification 475,372 also is referred to.

Filed: 1942-03-20
Abstract: 556,307. Air, compressing. BENDIX, Ltd., and IRVING, J. S. March 20, 1942, No. 3722. [Class 8 (i)] [Also in Group XXXIV] The liquid in a hydraulic brake system for vehicles of the kind comprising a master cylinder is normally maintained under pressure above atmospheric by the application of fluid pressure to a piston in the reservoir that is normally connected to the master cylinder. The fluid pressure may be produced by vacuum or by liquid air under pressure. As shown on Fig. 1 a pair of pistons 20, 23 slidable in the reservoir 10 are connected by a tube 18 slidable through a fixed partition 14. The lower chamber 16 containing the hydraulic liquid is connected by pipe 12 to the master cylinder and is filled through the tube 18 upon removal of the cap 19. The chamber 15 is connected by pipe 26 containing a non-return valve 25 to the induction system of the vehicle engine so that a vacuum is formed and pressure is thus applied to the piston against the action of a spring 24. The vacuum can be relieved by a valve 27. In a modification, the reservoir contains a single piston and the upper chambers may be connected to the pressure lubrication system of the engine or to a separate oil pump, the pressure being limited to the desired value by a pressure relief valve controlling an outlet from the chamber or by a valve arranged to cut off this oil supply. Instead of oil, air under pressure may be supplied to the upper chamber by an engine driven pump or as shown in Fig. 3 by a single stroke pump mounted on the brake or clutch pedal the pad 51 being provided with an extension 52 slidable on the pedal lever 50 so as to force air from the chamber 54 past a non-return valve 58 through pipe 59 to the reservoir when the brake or clutch is operated. The chamber 54 is normally connected to atmosphere by a passage 60 which is closed when the pad is moved. A pin and slot 55 limits the outward movement of the pad.

Abstract: 310,579. Siemens Bros. & Co., Ltd., and Coodwin, W. E. Feb. 7, 1928. Mouthpieces.-The mouthpiece a of a telephone transmitter is rotatably mounted in the transmitter casing c by a split ring or spring clip c located in a groove d in the extension b of the mouthpiece and adapted to engage the interior of the casing under the action of a spring tongue f which also prevents the entry of foreign material into the telephone casing. As shown the extension b is slotted, but the slots may be omitted and the clip e may be dished so as to exercise a spring action on the surface of the casing c and thereby produce a friction joint between the mouthpiece and the casing. The Provisional Specification describes an arrangement wherein a split ring co-operates with grooves in the mouthpiece and transmitter casing to lock those parts together.
