Title: Apparatus for recording the flow of gas or electricity
IPC: G01F15/00
Filed: 1930-11-08
Abstract: 361,586. Registering the flow of fluids &c. BREMNER, D.O., 30, Pont Street, Knightsbridge, London. Nov. 8, 1930, Nos. 33706/30, 35308/30, 37582/30, 15105/31, and 15955/31. [Class 106 (i).] A device for registering the consumption of gas, electricity, or other quantity comprises an independent agency operating a counter through a variable transmission gear controlled directly by the opening and closing of a valve or electric switch. In the form shown in Fig. 1, as applied to a gas apparatus such as a gas fire or radiator for registering the quantity consumed the spindle of the gas tap or valve 9 is provided with a cam 8 upon which bears a spring- controlled member 7 having means for supporting a wheel 4 adapted to slide axially along a spindle 5 driving a counting-mechanism 6. The wheel 4 makes contact with a driving wheel or disc 3 actuated by clockwork or synchronous motor 2, the arrangement being such that when the wheel 4 is over the centre of the disc the valve is in its closed position. In the application to electricity meters the valve is replaced by an electric switch of the rotary type with two or more contacts. Means may be provided to stop the clockwork movement when the current is switched off ; such means may comprise a solenoid the core of which arrests the action of the balance wheel. A mechanical stop action may be provided for this purpose and in addition may have means associated with it for imparting motion to the balance wheel when the valve is opened or switch is operated. Regulation of the supply may be controlled automatically as by means of a governor acting on the valve &c. spindle. Where an electric time-keeping unit is employed the flow through the meter is arrested if the current to the time unit 23 is interrupted by a circuit arrangement as shown diagrammatically in Fig. 9. A lock may be provided to co-operate with a projection on the valve &c. spindle to prevent unauthorized use thereof. To maintain a uniform pressure between the wheels 3, 4 the driving or driven parts may be hinged and pressed together by a spring or gravitational action. The lowest denominational wheel of the counting unit is marked in fractions as shown in Fig. 4. Instead of such markings the various sectors of the wheel may be differently coloured.

Abstract: 488,158. Wireless receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 9, 1937, No. 34143. Convention date, July 11. Addition to 472,739 and 478,775. [Class 40 (v)] In a radio receiver comprising high-frequency networks from which is derived a control voltage dependent on departure from tune with the incoming signal, and employing phase-comparison methods as in the parent Specifications 472,739 and 478,775, the two voltages whose mutual phase relation is compared are applied across opposite corners of a rectifier bridge. Fig. 4 shows a two-circuit band-filter L1, C1, L2, C2, coupled by a rectifier bridge G1 ... G4 such that the input and output voltages e1, e2, are applied each between one pair of opposite corners. The errorresponsive voltage u varies in sign and magnitude with the phase relation of el to e2. The bridge may be employed with filters of the kind having a common reactive coupling member, Fig. 5 (not shown). The network may comprise only one tuned circuit, the input then being shunted by an impedance the centre point of which constitutes one terminal of the control voltage u, Figs. 7 and 8 (not shown). The control voltage may also be derived by comparing the relative phase of the voltage across a parallel circuit L1, Cl, Fig. 10, and a series impedance comprising capacity or inductance represented by L3, L4 arranged symmetrically. Alternatively a series-resonant circuit may be employed such as L, 2C, 2C of Fig. 12 ; or two seriesresonant circuits LC as shown in Fig. 14, the control voltage being taken off from the shunt impedances' Z0, Z4. It will be noted that all the circuits are symmetrical, and thus require an input voltage which is also symmetrical about a constant potential. A non-symmetrical input may be adapted for the circuits of the invention by using a hybrid coil, or by connecting the constant potential terminal of the input source to a centre tapping on an inductance shunted across the network input terminals.

Abstract: 1525252 Flowmeter with foam sensor I DEKAN 19 Aug 1975 [20 Aug 1974] 34484/75 Heading G1A [Also in Division B8] This comprises a flow measuring mechanism connected to a totalling device and adjacent to a sensor giving, in the presence of foam, a signal which interrupts a totalling device, so that it registers and indicates only the total of liquid flow. In the thicker part 17 of connecting piece 2 is a window, through which infrared light from a photodiode is reflected on to a phototransistor by foam if it is present in the liquid passing to measuring chamber 16 Fig. 3, which has two sickle shaped openings E (inlet) and A (outlet) separated by wall 18. Rotary member 19 has castin permanent magnet 20, thus when it is moved via meshing teeth by piston 26, since the travelling cavity between the piston and the chamber wall conveys a certain volume of liquid, an alternating signal, of which the number of cycles is proportional to the amount of flow, is given out by Hall probe 28. The piston interior may also convey liquid. Probe 28 is connected via amplifier (30), Fig. 5 (not shown) to low-pass filter (31) and AND gate (32). If gas passes, the piston rotates rapidly and the high frequency pulses (over 10 Hz) are removed by the filter. The phototransistor supplies the other input to gate (32) which feeds, via amplifier and pulse shaper (35), five decade counter and indicator (5), which thus only counts when gate 32 receives signals on both inputs. Cone stopcock valve 14 connects to exit 3. A generator to supply the power required may be driven by member 19. Instead of the Hall probe a coil whose inductance is cycled by a magnetic element on member 19 or piston 26 may be used. The counter may be driven from the flow mechanism by a clutch which may be electrically engaged. The apparatus may be part of a beverage dispenser.

Abstract: 377,554. Electric incandescent lamps. WESTINGHOUSE LAMP CO., Bloomfield, New Jersey, U.S.A.-(Assignees of Anderson, W. E. ; 31, Columbus Avenue, Montclair, New Jersey, U.S.A.) Dec. 14, 1931, No. 34639. Convention date, Dec. 13, 1930. [Class 39 (ii).] In electric incandescent lamps adapted for series connection, for example for Christmas-tree illumination, the failure of a lamp due to the breakage of the internal filament circuit is indicated by a glow discharge within that lamp. The filament 16 is supported on leading-in wires 13, 14 which are spaced apart by a glass bead 15, and are adapted to function as electrodes by providing a coating of material such as magnesium or aluminium which may be provided by inserting a small slug of the material within the coils of the filament, so that when the filament is heated the material is vaporized and cleans up the residual impurities and is deposited in a thin layer on the wires 13, 14. Alternatively, the vaporizable material may be mixed with a suitable binder and sprayed upon the filament, or the filament may be dipped into the dry powdered material. The lamp bulb 10 is provided with a gaseous filling of either neon or argon, or a mixture of these at a pressure of from 10 to 40 millimetres. During the normal operation of the lamp the illumination is derived entirely from the filament.

Abstract: 346,453. Totalizators. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and BELAS, F. T., 24, Stanley Street, both in Liverpool. Jan. 13, 1930, No. 1242. [Class 106 (i).] In a totalizator employing rotating collecting switches individual to the various runners for transmitting bets from ticket-issuing machines to adding machines the operation of associating an adding machine with any collecting switch automatically affects the display of the corresponding horse runner number. The invention is described as applied to the totalizator system of Specification 342,261 and the drawings show the additional equipment necessary at each adding machine. When betting commences the necessary adding machines are connected by means of plug and jack connections to the collecting switches corresponding to the runner numbers. Jack springs for 80 runners are multiplied to the banks a, b of a rotary switch a .. f, contacts corresponding to horses numbered 1 and 41, 2 and 42, .. being commoned, the necessary discrimination being effected over a jack spring P, one of which is associated with each spring corresponding to spring 1. Operation. When the main and individual betting start keys are depressed earth is extended over lead 101, contact k5, two windings of relay S, resistance Y (common to S relays of all adding machines) to battery. Relays S locks up over contact s1 shorting its high-resistance winding whereby the resistance Y renders it impossible for any other S relay to operate. A relay DR is energized over contacts s4 and closes contacts dr1 to energize the switch driving magnet DM which contacts with relay DR to step the rotary switch continuously until the wiper a or b reaches the contact marked by the jack from the collecting switch in use, (say number 1) when the relay K is energized over contacts s3 and locks up over contacts k1, jack 1, contacts k2, resistance X. Contacts k4 break the circuit of relay DR, contacts k7 break the locking circuit of relay S so that other S relays may now operate and contacts k5, k6 close circuits over wipers c, d and e, f which display respectively the tens and units digits of the runner number on a monogrammic lamp indicator as in Specification 338,897, [Class 106 (i), Calculating &c.], the control leads 102, 103 which initiate the operation of the display units being energized from lead 101 independently of wipers c .. f. In the case of jacks corresponding to horse numbers 40 .. 79 the P springs are permanently earthed so that when the relay K operates a relay CO is operated over contacts k3, and over contacts co1 .. co4 produces circuit changes in the tens digits to give the correct horse number. When place betting is permitted, a relay, operated by the place-betting start key serves to connect up similar display units for the appropriate runners, one runner number being used for both win and place indicators. The rotary switch may be displaced by a combination of relays which may control the lamp display direct.
