Title: Improvements in or relating to apparatus for filling containers with liquid
IPC: B67D7/48
Filed: 1949-05-25
Abstract: 664,097. Filling nozzles. GIGER, E., and SIDLER, A. May 25, 1949 [May 25, 1948], No. 14015/49. Classes 21 and 125(ii). (Also in Group XXIX] A filling nozzle of the type in which a valve, normally urged towards its closing position, is held in its open position during the delivery operation by a catch means controlled by a diaphragm located in a chamber subjected to suction action when a predetermined level is reached, whereby the diaphragm effects release of the valve, is provided with means whereby the sucking of liquid into the diaphragm chamber is prevented. In the filling nozzle shown, depression of handle 43 raises a valve lifting member 40 causing a spring urged latch 46 to lift valve 45, thus allowing liquid to flow from the nozzle inlet 47 into the container. In its flow, at least part of the liquid passes through an ejector nozzle 13, the flow inducing a partial vacuum in a chamber 15 surrounding the nozzle. Two air passages 20b and 20c enter the chamber 15, the passage 20b, which ends in a mouth 18 situated near the outlet end of the filling nozzle, communicating with the air space in the container and passage 20c with a chamber 31 closed on one side by a diaphragm 32, the chamber having an outlet duct 20d to atmosphere. During the filling operation, air from the container is sucked up passage 20b by the ejector nozzle and returned to the container, passage 20d being closed by a valve 33 urged on to its seating by a spring 35 when a cranked lever 36 is disengaged by the upward movement of member 40 and the diaphragm urged outwardly by a spring, so maintaining a latch 49 in engagement with a spring plunger 41. When the liquid rising in the container reaches the mouth 18 it seals passage 20b and a partial vacuum is immediately produced in chamber 31 by the ejector 13. Diaphragm 32 is drawn in releasing plunger 41 which trips the latch 46 allowing a spring 50 to close valve 45, stopping the liquid flow. Simultaneously the plunger engages the nose 38 of lever 36 which moves to raise valve 33, thus opening the chamber 31 to atmosphere and so preventing the sucking up of liquid into the chamber.

Filed: 1962-04-11
Abstract: 966,467. Radio direction finders. MARCONI CO. Ltd. Nov. 21, 1962 [April 11, 1962], No. 14048/62. Heading H4D. To overcome errors due to pointto-point variation of the incoming signal strength, a direction finding system comprises a plurality of geographically spaced self-orientating direction finders each providing a signal representative of the momentary incoming signal direction of the direction finder, means for controlling the strength of each such direction representative signal in dependence upon the strength of the received signal at the respective direction finder, and means for combining the thus strength controlled signals to provide a resultant signal for indicating the direction of the station being received. The arrangement shown comprises 11 similar direction finders X 1  to X 11 , one of which is shown in detail. The said one direction finder comprises four fixed aerials 1, 2, 3 and 4 and a radiogoniometer comprising stators 5 and rotors 6. The rotor is rotated by a motor 7 under the control of a signal from a receiver 8 which receives the signal from the rotor 6 and a sensing aerial 9, such that the rotor 6 is automatically rotated to the incoming signal direction. The motor 7 also rotates the permanent magnet of an A.C. generator comprising a rotor 12 rotated by a motor 13. The output of the motor 12 is thus an A.C. signal having a phase representative of the incoming signal direction. A reference signal is generated by a second A.C. generator comprising a rotor 16 also driven by motor 12 and a fixed permenent magnet 17. The receiver 8 is of the A.G.C. type, and the A.G.C. signal thereof is used to control, via D.C. amplifier 14, the gain of an amplifier 15 amplifying the output of rotor 12. The resultant signal is passed via a resistor R1 to the input of a selective amplifier 18, together with the outputs of all the other direction finders. The amplifier 18 extracts the average phase of the inputs and the output of the amplifier is fed to a phase discriminator 19 together with the reference signal from rotor 16, to give an indication of the direction of the signal source on indicator/recorder 21.

Title: Pulse Discrimination Circuit.
IPC: G11C11/06
Filed: 1968-03-25
Abstract: 1,189,735. Pulse discriminating circuits; magnetic storage arrangements. BURROUGHS CORP. 25 March, 1968 [27 March, 1967], No. 14188/68. Headings H3B and H3T. The threshold value of a binary pulse amplitude discriminator varies with time within range of possible values of the pulse. Thus, in Fig. 6, during the strobing interval T 1 , T 2  the threshold level, shown dotted, follows an exponential path just above the unwanted pulse 18 so that the whole of the energy in the shaded area is available. The invention is described as applied to a core memory system, Fig. 1, in which the signal pulse is compared with a threshold formed from the sum of a strobe pulse at S and an exponentially varying voltage from 10. The latter may be generated by a capacitor which is charged through the diode by the base voltage of the strobe pulse so that when the strobe pulse exists and the diode is thus cut off, the capacitor discharges through a resistor (Fig. 3, not shown). Alternatively, the exponential voltage may be generated by discharging an inductor (Fig. 3, not shown). A number of discriminators can be supplied from a common exponential voltage generator (Fig. 4, not shown).

Abstract: 601,380. Transformers. BOUCHEH INVENTIONS, Ltd. Aug. 8, 1944, No. 15046. Convention date, June 25, 1942. [Classes 38 (ii) and 38 (iv)] A transformer for supplying luminescent lamps comprises a primary and two secondary windings on the same main magnetic core, there being a magnetic shunt between the primary and one of the secondary windings and a condenser in series with the other secondary winding which is adjacent the primary. Primary winding 16 energized from a source 19 is wound on a centre limb 11 of a core 10. A secondary winding 20 wound closely round the primary supplies a fluorescent gas discharge lamp T, which has a condenser C in series to improve the power factor and limit the value of the current. A second lamp T 2  is supplied from another secondary winding 21 connected in autotransformer relationship with the primary 16, so that it receives the sum of the voltages in primary 16 and secondary 21. When the arc in lamp T 2  is extinguished at the end of each ¢ cycle, the flux passes through centre limb l and yoke 15 to induce sufficient voltage in secondary 21 for the voltage as it rises across lamp T 2  to restrike the arc, whereupon the flux is immediately diverted through the shunts SH 1 , SH 2  and across airgaps G 1 , G 2 , little voltage then being induced in secondary 21 ; the voltage across lamp T 2  falls but remains just sufficient to keep the arc in being during the rest of the ¢ cycle.
