Filed: 1976-04-14
Abstract: 1522892 Automatic control of pressure ETABS POMPES GUINARD 14 April 1976 [15 April 1975] 15288/76 Heading G3R A physical variable e.g. water pressure is maintained at the desired level by varying the number of pumps P 1 -P 3  in response to a pressure detector 1. Pumps P 1 -P 3  are connected between supply lines L 1  and L 2  by starting contacts 8 and also by continuous supply circuits e.g. 13, t 1 , R 1 . A low pressure causes the starting circuits of each pump in turn to be energized by rotation of cams 7 1 -7 3  after which the continuous supply circuits hold the pumps on. A high pressure on the other hand causes timer T to be energized. This cuts out each continuous supply circuit in turn, according to built in delays, via contacts t 1 -t 3  leaving only that pump which happens to have its starting circuit energized, operative as a holding pump. A timer T' ensures that the pump starting cams 7 1 -7 3  always come to rest in such a position that when they are next rotated a pump will be started immediately.

Title: Electromechanical transducer for limited rotation
IPC: H01F7/14
Filed: 1962-04-19
Abstract: 987,178. Electric measuring instruments. MECHANICS FOR ELECTRONICS Inc. April 19, 1962 [April 24, 1961], No.15310/62. Heading G1Q. An electromechanical transducer designed for limited angular movement and suitable for use as part of a measuring instrument comprises a rotor capable of rotation between two poles energized from a first magnet, at least one of the poles having two pole pieces spaced apart by a gap in the direction of rotor rotation, and a second magnet energized by the control current coil arranged to produce a second magnetic field between the two pole pieces of the one pole by way of the rotor. The flux path for the first magnet has a relatively high reluctance so that substantially none of the field of the second magnet passes through the first magnet. An instrument embodying these features includes a permanent magnet 10, and four flux carriers 22, 24, 26 and 28 of soft magnetic material connected in pairs by the posts 30 and 32. Control coils 42 and 44 are wound around these posts, and a velocity pick off coil 46 extends generally round the armature assembly 12. The shaft 50 of the armature rotates in frictionless bearings on non magnetic support plates 72, 74, and is attached to a torsion wire 78 which provides the restoring force required of the measuring instrument. The shaft 88 may carry a pointer or pen to provide the indication. The control current passes through the coils 42 and 44 in such directions as to cause the armature to rotate, and the motor torque is directly proportional to this current. The velocity of rotation may be picked off as a voltage in the coil 46 for use with servo control. Advantages of this type of movement are that it has a high ratio of torque to moment of inertia, low hysteresis losses, may be easily miniaturised and eliminates the disadvantages inherent with moving coils. Other embodiments are described where a single non moving control coil extends around the armature (Fig. 6 not shown), whose four control coils are used (Fig. 8 not shown), and where the armature axis is perpendicular to the phase of the main magnet system (Fig. 9 not shown). In these embodiments the flux carriers 18, 20 are not split into separate arms, and only the pole pieces are separated.
