Patent GB-922310-A (GB)
Title: A new or improved spraying device
IPC: A61M15/00
Filed: 1960-11-07
Abstract: 922,310. Spraying measured quantities. SOCIETE TECHNIQUE DE PULVERISATION. Nov. 7, 1960 [Nov. 10, 1959], No. 38239/60. Class 69 (3). A liquid sprayer comprises a body 1 carrying a liquid container 2 and a compressed-air reservoir 11 and having a Venturi-type spray nozzle 9 connectable to the container 2, and a spring-loaded plunger 6 slidable in a bore 4 in the body 1 and having a necked portion defining with the bore 4 an annular metering chamber 7 which normally communicates via a passage 10 with the reservoir 11 whereby it is filled with compressed air, the plunger being operable manually to move the chamber 7 out of communication with the reservoir 11 and into communication, via a passage 8, with the nozzle 9 to discharge the air in chamber 7 therethrough so that a metered quantity of liquid spray is dispensed. As shown, the plunger 6 is rotatable in the bore 4 between the position shown in Figs. 1 and 2 for metered spray delivery, to a position where a longitudinal groove 20 in the plunger extending from the chamber 7 is brought into alignment with the passage 10 so that on depression of the plunger to spraying position the reservoir 11 is maintained in communication with the chamber 7 and a continuous spray results for as long as the plunger is depressed. Retention of the plunger in the desired angular position is effected by a disc 16 keyed to the finger-end of the plunger and secured to the body 1 by a screw 18 located in an arcuate slot 19 of the disc, an arrow 21 on the disc co-operating with index marks C and D on the body 1 to indicate respectively the continuous and metered positions of the plunger. For use with the inverted liquid container 2 shown in Fig. 1, the plunger 6 is extended integrally to terminate in a head 13 which normally seals the container 2 from the passage 12 in the body 1 which leads to the nozzle 9, the head 13 being unseated immediately on depression of the plunger. For use with an upright container employing the usual dipper tube, the valve head 13 may be carried on a separate spindle slidably displaceable in an axial bore of the plunger against the action of a weak spring to provide a lost-motion connection with the plunger.
Patent GB-855725-A (GB)
Title: Improvements in or relating to rectifying apparatus having at least one semi-conductor rectifier member
IPC: H02M7/40
Filed: 1956-12-17
Abstract: 855,725. Rectifying. SIEMENS-SCHUCKERTWERKE A.G. Dec. 17, 1956 [Dec. 17, 1955], No. 38497/56. Class 38 (2). Associated with silicon, germanium or other semi-conductor junction rectifiers such as 2, 3 connected in bi-phase to supply D.C. load 7 from transformer 1, are means such as capacitors 8, 9 to reduce or prevent the flow of inverse current pulses upon application of inverse voltage to the rectifiers. The presence of the capacitors together with the transformer leakage reactance or added inductance (Fig. 5, not shown) reduces the rate of rise of inverse voltage. To prevent current surge upon capacitor discharge when forward current flow begins, a high value discharge resistance is connected in parallel with each capacitor (Fig. 7, not shown). Oscillations developed by the capacitor-inductor circuit may be obviated by connecting a resistor and inductor in parallel with each capacitor (Fig. 9, not shown). The inductor may be replaced by series-connected capacitor and resistor (Fig. 11, not shown). If, as shown, 4 and 5 are the switches of a contact converter, the normal switching chokes 18, 19, Fig. 13, may absorb the inverse voltage long enough to prevent the occurrence of the inverse current pulse. The switching chokes may carry biasing windings which may be used for voltage control. The rectifiers may be in star or bridge polyphase arrangements.

Title: Synchronizing mechanism
IPC: H02P5/52
Filed: 1956-12-27
Abstract: 848,209. Automatic speed-control systems. UNITED AIRCRAFT CORPORATION. Dec. 27, 1956 [Dec. 27, 1955 (2)], No. 39348/56. Class 38 (4). Propellers 12, 26, Fig. 1, are driven by motors 10 and 24, the speed of which is maintained constant by automatic adjustment of the blade pitches by hydraulically actuated pistons controlled by flyball governors 14, 28, the governor spider spring being adjustable and the adjustment being effected by a step-motor 16, 30 controlled by a commutator switch 18, 32. The commutator switch 18 for the master propeller 12 is driven by a manually-controllable D.C. motor and that for the slave is driven by a two-phase motor 34 controlled by electronic synchronizing and phasing apparatus which employs pulses produced in coil 36 by the rotation of the propeller in the manner described in Specification 846,913. Wave former unit 40, Fig. 2, and sawtooth sampler 74 producing an error signal input to chopper amplifier 112, 114. Manual phase control is provided by potentiometers 128 across a separate source 130, 132 and switches enable individual control by manuallycontrolled commutator switches such as 33 or the selection of an alternative propeller as master. The mechanical lag of the chopper is increased by additional lag in the transformer to produce in the control winding of motor 34 a signal lagging or loading the reference voltage by 90 degrees and feed-back is provided by the wiper of potentiometer 172. The amount of reset of the governors is limited by a pin 180 in a slot 182 of a gear-wheel 178 driven through gearing by the motor 34 and the potentiometer 172 is arranged to give zero output when the pin 180 is in the centre of the slot. A pushbutton 184 is provided whereby phase correction may be achieved after correction which has been made for an off-speed error leaves a phase error and wiper 172 in an off-centre position neutralizing a phase error signal. Operation of switch 184 energizes relay 186 which earths the error signal and de-energizes relay 188 to transfer governor reset motor 30 to commutator switch 18 controlling the master. The fed-back signal from 172 is in the meantime effective to return the wiper to its mid-point so that phase errors can be corrected. In cases of large error more than one actuation of the push-button may be necessary. Specifications 530,111, 678,505, 681,348 and 700,394 are referred to.

Filed: 1964-10-14
Abstract: 1,114,928. Transistor switching circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. 1 Oct., 1965 [14 Oct., 1964], No. 41863/64. Heading H3T. A transistor circuit comprises a transistor 16, means for periodically applying pulses to the base of the transistor, switching it on (negative pulses applied at terminal 15), and means sensitive to the collector-emitter voltage of the transistor for switching the transistor off when the collector emitter voltage exceeds a predetermined value. A load resistance is connected between points 13 and 14 and if, when a pulse occurs, the load is below a predetermined value, the potential of point 14 is held close to that of terminal 11. Diode 18 is thus cut off and capacitor 21 charges until Zener diode 22 breaks down, rendering a further transistor 23 conductive which conduction removes the base current from transistor 16, which cuts off. However, if the load is above the predetermined value, the potential of point 14 is held close to ground through the saturated transistor 16, diode 18 conducts and prevents capacitor 21 charging sufficiently to break down Zener 22, and transistor 16 continues to conduct. At the end of each pulse, transistor 16 cuts off and capacitor 21 discharges through the pulse source. Fig. 2 (not shown) depicts a further embodiment in which transistor 16 is replaced by a plurality of transistors having common emitter, collector and base connections, each emitter lead having its own resistance. The pulses are applied through a transformer,the secondary of which is connected between point 12 and resistance 19, resistance 17 being connected to an intermediate point on the secondary. The invention may be employed in connection with railway signalling, terminals 13, 14 being connected to a pair of rails in a section, a high load indicating the absence and a low load the presence of a train.
