Abstract: 1373134 Protecting amplifier circuits; loudspeaker circuits PIONEER ELECTRONIC CORP 7 Dec 1971 [7 Dec 1970] 56870/71 Headings H3T and H4J [Also in Division H2] In an amplifier arrangement comprising an amplifier 1 provided with a detecting circuit 3 for providing a detector output signal to a twostate protecting means 4 when the magnitude of the resistance of a load 2 coupled, in operation, to the output of the amplifier 1 is less than a predetermined value, the detecting circuit 3 comprises a resistive bridge circuit R3, R5, R7, D2, RL or R4, R6, R8, D3, RL, one leg of which is arranged to include the load RL, the resistances in the legs of the bridge are selected to provide a balanced bridge when the resistance of the load corresponds to the predetermined resistance value and the protecting means 4 is arranged to switch in response to the detector output signal from its first operative state in which the load 2 is arranged to receive an output signal from the amplifier to its second operative state in which the load does not receive an output signal from the amplifier. When the predetermined load resistance RL is connected to the output of the amplifier 1 the bridge circuits are balanced and a transistor Tr 4  remains cut off. If the load resistance, such as a speaker, RL becomes less than the predetermined value, and push-pull amplifier transistors Tr 2  and Tr 3  are on and off respectively a diode D2 conducts and the bridge circuit formed by R3, R5, R7, D2 and RL becomes unbalanced so that transistor Tr 4  turns on to operate a protecting circuit 4. When the protecting circuit 4 which may be a relay is operated the main amplifier 1 is disconnected from the load or is disconnected from the driver circuit. Similarly if the load resistance RL becomes less than the predetermined value and amplifier transistors Tr 3  and Tr 2  are on and off respectively a diode D3 conducts and the bridge circuit formed by R4, R6, R8, D3, RL becomes unbalanced so that transistor Tr 4  turns on to operate the protecting circuit 4. The capacitor C2 prevents Tr 4  switching on during the delay of switching off of the push-pull power transistors Tr 2 , Tr 3 .

IPC: G05D16/06
Filed: 1970-12-04
Abstract: 1301950 Hydraulic pressure reducing devices WERNER & PFLEIDERER 4 Dec 1970 [6 Feb 1970] 57812/70 Heading G3P A hydraulic pressure reducing device comprises a leaky differential piston 8 co-operating with a valve seat 4 to control flow between an inlet 5 and an outlet 6, a transfer valve 11 controlling communication between chambers 10 and 12, a bellows 15 containing compressed air and hydraulic fluid, and a safety valve 17. In use, compressed air is fed through a passage 20 into the interior of the bellows until the pressure which is required at the outlet 6 is reached. This pressure extends the bellows and causes the plate 16 to lift the valve 11. The chamber 10 is thus relieved and the piston 8 is lifted off the seat 4 by the inlet pressure. The hydraulic fluid flows through the open valve until the pressure at the outlet 6, transmitted through the pipe 25, lifts the plate 16 upwards and causes the valve 11 to shut. The pressure in the chamber 10 and inlet 5 now equalizes through gap 24 whereupon a spring 13 forces the piston 8 onto the valve seat 4. For raising or lowering the outlet pressure, the air pressure in the bellows is raised or lowered. This can be done by introducing or removing hydraulic fluid through pipes 19 and 26. The pipe 26 enables hydraulic fluid to be withdrawn without the loss of air. If the pressure at the outlet becomes excessive the plate 16 is lifted further by the pressure and opens the safety valve 17.

Abstract: 757,409. Interrupters. LUCAS (INDUSTRIES), Ltd., J. Dec. 15, 1954 [Dec. 15, 1953], No. 34871/53. Class 38(5) In an interrupter for engine spark ignition apparatus a carrier h for a pair of contact pieces ki which are adapted to be separated by the action of a cam q is capable of angular movement relative to a supporting plate a to vary the timing, and support between plates is effected by means of three abutment pieces and a loading spring in order to ensure smoother relative movement. In the form shown one of the abutment pieces s is rigidly attached to the back of the plate h and passes through an arcuate slot f in plate a which it engages by the shoulder t. The position of s is such that the contact finger u, the centre of the cam and s are in one straight line. Two studs r of nylon or similar material also attacher to h form the other two abutment pieces and are situated on a chord perpendicular to the aforementioned line. The spring g, v which is attached to plate h behind the contacts acts against the plate a and tends to tilt plate h about the studs r as pivot. The direction of tilt is the same as that caused by the action of the cam whereupon smoother movement of the carrier is effected. In other arrangements the abutment pieces and spring may be attached to plate a and the spring may be in other appropriate positions.

Patent GB-2008668-A (GB)
Title: Dosage Pumps
IPC: B01L99/00
Filed: 1978-11-21
Abstract: A dosage pump for accurately dispensing small quantities of liquids has a piston (32) with two different diameter portions which extend through opposite sides of a pump chamber (3). Reciprocation of the piston (32) changes the internal volume of the chamber (3) unoccupied by the piston and affords a pumping action. Since the differences in diameter of the piston portions can be made very small, even with moderate stroke lengths small quantities of liquid can be dispensed with accuracy. Provision is made for adjustment of the stroke length to provide for variation in delivered volume. The pump is suitable for use in analytical applications. <IMAGE>

Title: Improvements to Eddy Current Retarders Particularly for Vehicles
IPC: G05D13/00
Filed: 1979-02-21
Abstract: An eddy-current (vehicle) retarder, has an electronic control unit 3 actuated by means of a multiposition handle 4 to connect a D.C. voltage source 2 of amplitude V to the inductor windings 1 of the retarder. The windings 1 are arranged so that their supply at a voltage of 0.65 V volts causes the retarder to develop its maximum permissible braking torque for permanent operation, and the electronic unit 3 transmits a voltage increasing from 0 to 0.65 V volts when the handle 4 is moved from its first position O to its last but one position C, this voltage becoming equal to V only when the control handle is moved into its end position D against a spring 6 to give braking over torque, the spring 6 acting as a safety means. The period of over- excitation corresponding to this last position may be limited by other safety means, e.g. a timing device (optionally adjustable), or means sensitive to temperature of an element heated by the retarder or to any parameter tied to such a temperature. <IMAGE>
