Title: Improvements in and relating to switching systems employing saturable reactors
IPC: H01H33/59
Filed: 1949-09-13
Abstract: 658,381. Control systems for consumption apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 13, 1949, No. 23609. Convention date, Sept. 24, 1948. [Class 38 (iv)] A switching system for a high current load circuit 2 which minimizes the usual arcing across the switch contacts 3 comprises a saturable reactor 7 having its A.C. windings 8 in series with a second switch 11, which opens after the first switch, shunted across the first switch 3 with means for regulating the current in its A.C. winding 9 to vary the saturation of the reactor such that when the first switch 3 is opened the saturated reactor carries the load current and its saturation is automatically decreased, and so as to increase its impedance, until the switch 11 opens under delay and interrupts the load current at a low value. The two switches may comprise normally closed contacts of a relay 25 as shown, a time delay being imparted to the second relay contact 11. The D.C. winding 8 may be supplied over a rectifier 14 from a transformer 23, the primary of which may be connected either across the load (Fig. 1, not shown), in series with the load (Fig. 2, not shown), or across the supply leads 4, 5, as shown. In the two former connections a condenser and resistance in series are shunted across the A.C. winding to absorb the initial transients when contact 3 is opened. In the third connection, the transformer primary is connected through a third contact 24 on the relay so that when the relay operates the flow of saturating current is interrupted and automatically decays.

Abstract: 803,233. Inflatable craft. ELLIOT EQUIPMENT Ltd. July 31, 1957 [July 31, 1956], No. 23634/56. Class 113. [Also in Group X] A compensating means for maintaining in shape when inflated an inflatable craft in which the inflatable envelope is inelastic, comprises elastic constraining means arranged for exerting an external compressive force on an inflatable member when inflated in such a manner that when a fall in temperature causes the pressure in the member to fall the elastic constraining means reduces the volume of said member thereby compensating the pressure in the envelope. In Fig. 1 said member comprises a bag 2 of inelastic material in communication with the inflatable tube 1 of a life raft via tubes 3. Elastic strips 5 are spaced along the axis of the bag which bulges outwardly as at 6 when inflated. When the ambient temperature falls and the inflating gas pressure decreases, the strips 5 contract to reduce the volume of the bag 2 thereby causing the pressure in the bag and the tube 1 to be maintained. In Fig. 2 said member comprises the arch 7 and base tube 8. The elastic strips 9 extend half-way round the inner surface of the arch and are secured thereto by patches 10. When the temperature, and hence the pressure, fall, the strips contract to reduce the volume of the arch, as shown chaindotted, and hence maintain the pressure in the inflated members.

Filed: 1966-05-26
Abstract: 1,179,114. Rolling. DAVY & UNITED ENG. CO. Ltd. 26 May, 1967 [26 May, 1966], No. 23737/66. Heading B3M. [Also in Division G3] In an automatic control system for a rolling mill, a thickness error signal controls screwtype loading to correct thickness and a signal proportional to the screw-loading controls auxiliary hydraulic loading to maintain the screw-loading constant or within predetermined limits. In Fig. 1, pressure is applied to work rolls 21, 22 of a rolling mill by back-up rolls 16, 17 journalled in chocks 14, 15 which are located in a housing 12 and urged together by a screw 25 and hydraulic actuators 31, 32. A signal F from a load cell 23 measuring total rolling load and a signal S 0  from a transducer measuring screw setting are applied to a unit 8 which produces a signal representing rolled material thickness and compares it with the desired thickness set by a potentiometer 7. The resulting error signal corrects thickness by controlling screw motors 10. A signal corresponding to the screw loading is produced by a unit 2 which subtracts a signal P corresponding to the hydraulic pressure applied to actuators 31, 32 from signal F corresponding to the total rolling load. This screw loading signal is compared at 4 with a desired screw loading set by a potentiometer 3 and the resulting error signal maintains the screw loading constant or between limits by controlling a valve 5 applying hydraulic fluid to actuators 31, 32. In one modification, the hydraulic actuator force is transmitted through the screw operated member. In another modification, both the screw and the hydraulic actuators act on a pair of wedges which have ball-bearing or other friction reducing means and are located between housing 12 and chock 14.

Filed: 1963-06-14
Abstract: 1,013,472. Orientating cigarettes on conveyers. K. KÍRBER. June 14, 1963 [June 15, 1962], No. 23765/63. Heading B8A. [Also in Division A2] Cigarettes are carried in the grooves of rotary conveyer 1, the alternate cigarettes C and C1 forming two staggered rows as shown in Fig. 4. These are caused to be delivered to rotary conveyer wheel 4 to fill the grooves thereof with the rows C and C1 displaced so that they are aligned as shown in Fig. 4. This displacement of the two rows is effected by the grooved wheels 2 and 3 which are formed of equal diameter but with their centres 21 and 31 displaced as shown. Thus the row C of cigarettes is carried in the grooves of wheel 3 whilst the row C1 of cigarettes is carried in the grooves of wheel 2, and the displacement of the two wheels causes the path taken by the cigarettes C to exceed the path taken by the cigarettes C1. The effect is that cigarettes C and cigarettes C1 which occupy different grooves of wheel 1 are caused to occupy the same groove of wheel 4. This enables a double-sized filter tip to be dropped in each groove of wheel 4 between the displaced cigarettes therein so that each groove of wheel 4 forms two cigarettes complete with tips. The wheels 1, 2, 3 and 4 are carried in a frame which is pivoted about the centre of wheel 4 so that wheel 1 may be adjusted to receive cigarettes from a cigarette-making machine.
