In Fig. 1 a 10-stage shift register has feedback from two stages via an exclusive OR-gate 11 arranged for maximum periodicity in the usual way. The outputs of two stages are added by the gate 20 and multiplexed at twice the clock frequency with the output of a third stage. In a modification (Fig. 2, not shown) the multiplexer operates at four times the clock frequency, three of the inputs to the multiplexer coming from exclusive-OR gates (21, 22, 23). In another embodiment (Fig. 3) two shift registers, comprising stages 1, 3, 5, 7, 9 and 2, 4, 6, 8, 10 respectively, each have their last stage connected to their first and to the first stage of the other by an exclusive-OR gate 51, 52. The multiplexer is fed by the output of one stage of each register. In a further embodiment (Fig. 4) there are three shift registers, comprising stages 4, 7, 10, 3; 6, 9, 2 and 5, 8, 1 respectively, the outputs of the last two stages of each register being connected by an exclusive-OR gate to the first stage of the next.

When an off-shore drilling operation is completed, the telescoped well casings 20, 22, 24 are parted off by a cutter head 34, Fig. 3, and removed from the well. Head 34 comprises a number of replaceable cutters 52, pivoted on a body 38 connected to a drill string 16, by a sub 36, and a hydraulic piston 40 in the body co-operates with the cutters so as to pivot them into the horizontal cutting position against the action of a spring 48. In operation, the drill string is passed into the inner casing 20 until a swivel assembly 30 rests on the casing shoulder 32, Fig. 1. Piston 40 is actuated, so that cutters engage the wall of casing 20, the drill is rotated, and casing 20 is parted off. The drill string is removed from the casing, sub 36 is replaced by a shorter sub, cutters 52 are replaced by longer cutters and the operation is repeated, so that the cutters pass through the groove previously produced in casing 20, and part off casing 22. The same procedure is carried out for parting off casing 24, the drill string is retracted, and the casings are removed.

Abstract: 574,783. Ignition systems. BENDIX AVIATION CORPORATION. Feb. 17, 1944, No. 3000. Convention date, Jan. 22, 1943. [Class 7 (iv)] In an ignition system for internal-combustion engines, the closure of -the ignition switch when the engine is cold does not complete the ignition circuit until after a time lag, so that the engine is first turned to fill the cylinders and then the ignition becomes effective. In Fig. 1, the starting motor circuit is oonmpleted by starter switch 11 which operates the magnetic switch 4. The ignition switch 12 is connected to a thermostatic snap switch 15 which in turn is connected to the primary 17 of the usual ignition coil 18 associated with timing mech.- anism 19. The switch 15 comprises a flexible blade 24 moved between contacts 26, 27 by a bimetallic strip 31 connected to the blade by a toggle spring 32. A heater coil 36 surrounds the strip and is in circuit between lead 14 and the switch blade. When the engine is cold, the switch is in the Fig. 1 position and closure of ignition switch 12 completes the heater coil circuit. After a few seconds, the switch is moved over to contact 27, thereby completing the ignition circuit. The reduced current passing through heater coil keeps this coil warm while the engine is operating. In a modification, Fig. 2, the heating circuit is completed by starter switch. In this form, the ignition switch is first closed and subsequent operation of the starter switch completes the heating circuit and causes completion of the ignition circuit after a short delay. The temperature of the strip 31 is maintained during operation by heat conducted from the engine.

Abstract: 1,240,918. Controlling vehicles. CLARK EQUIPMENT CO. 16 Dec., 1969 [15 Jan.' 1969], No. 61366/69. Heading B7H. The speed of an engine driven truck which performs a lifting or tipping function, e.g. a fork lift truck has a control system which permits the driving of a pump for the lifting &c. function without varying the speed of the truck. As shown, a fork lift truck is driven by wheels 106 driven by a hydrostatic motor 118 supplied through a manoeuvring valve 119 by a variable displacement pump 27 controlled by a servovalve 10 and driven by an engine 30 which also drives fixed displacement pumps 1 and 26. At idling speed of the engine, pump 1 supplies a predetermined amount of oil to a control valve 4 creating a back pressure in a line 2, thereby causing a cylinder 12 to nearly close carburetter butterfly 13. An accelerator 15 increases engine speed by opening an orifice 5 in the valve 4, thereby decreasing pressure in cylinder 12 which causes butterfly 13 to open and so increase engine speed. When operation of the lift is required at maximum speed while driving the truck at low speed, a handle 22 is actuated from right to left to supply oil from the pump 26 to lift cylinder 116 and to bleed line 7 through the lift valve 8, thus causing an increase in engine speed by operation of butterfly 13. The servo valve 10 decreases the displacement of pump 20 to compensate for the increase in engine speed, such that truck speed is not increased.
