IPC: G06K19/06
Filed: 1957-04-23
Abstract: 858,583. Sorting cheques. RANK CINTEL Ltd. April 22, 1958 [April 23, 1957], No. 12924/57. Class 106 (1). A document 1, Fig. 1, e.g. a cheque, has a strip of magnetic material 2 for recording data showing the origin of the cheque. The strip may be duplicated symmetrically at each end so that either end can be presented to the senser. The strips may be curved because the sensing heads 19, Fig. 3, are carried on rotating arms 20 or the area may be extended as shown at 4 to facilitate application. During sensing movement of the rotating sensing head is synchronized with the cheque feeding mechanism. Recording is effected by inserting the cheques while still in the book into a simple machine in which they pass between the poles of gapped ring magnets. A high-frequency bias field may be provided to assist magnetization during the recording. Sorting.-In the form of Fig. 4 the cheques are taken in turn by a sucker 29 on an arm 31 and carried over a line of sensing heads 37, the sensed data causing one of three solenoidoperated hammers 38, 39, 40 to displace a corresponding one of three pins 34, 35, 36 slidable transversely through the arm. The projecting pin strikes a corresponding abutment 41, 42, 43 and stops the arm with the cheque presented to one of three suction grippers which are associated with separate bins. There may be provision for more than three catagories. Specification 844,065 is referred to.

Title: Nozzle assembly for a jet propulsion engine
Inventor: PIKE MALCOLM ROY
IPC: F02K1/12
Filed: 1965-03-26
Abstract: 1,038,854. Jet nozzles. ROLLS-ROYCE Ltd. March 26, 1965, No. 13079/65. Heading F1J. A nozzle assembly for a jet propulsion engine comprises a convergent nozzle which is mounted within a shroud having a fixed divergent nozzle at its downstream end, there being means for effecting relative axial movement between the shroud and the convergent nozzle so that the shroud may be placed both in an operative position in which it controls the expansion of jet gases leaving the convergent nozzle and in inoperative position in which it does not exercise such control. The invention is described with reference to a gas turbine by-pass type jet engine which comprises a jet pipe 14 having at its downstream end a convergent nozzle 15, the nozzle comprising a series of flap members 24 which are mounted at their upstream ends for pivotal movement about pivots 25 whereby the area of the convergent nozzle may be varied. Disposed around the nozzle 15 is a shroud member 21 which is axially movable by means of rams 22, Fig. 1, not shown, the shroud having at its downstream end a divergent nozzle portion 23. The shroud member 21 is movable axially between the operative position shown in Fig. 2 in which the divergent nozzle portion is effective to control the expansion of the jet gases leaving the convergent nozzle portion 15, and an inoperative position upstream of the position shown in Fig. 2. Each flap member 24 of the convergent nozzle portion has a curved portion 26 associated therewith and rollers 30 and 35 carried by the shroud member 21 by means of brackets 32 engage one above and one below the curved flange 26 so that as the shroud member 21 is moved axially downstream to the operative position shown in Fig. 2 the rollers act on the curved flanges 26 so as to pivot the flap members 24 of the convergent nozzle portion to their maximum area position. As the shroud member is moved axially upstream to the inoperative position the rollers act on the flap members 24 to move them to the minimum area position. The by-pass passage is indicated at 17 in Fig. 1. An outer casing 18 is disposed around the engine casing 16 to define therewith an annular passage 19 through which air may flow from the intake 10<SP>1</SP> to the annular space 20 around the convergent nozzle portion 15, the air then entering into the nozzle by ejector effect of the exhaust gases.

IPC: G01V3/02
Filed: 1957-04-30
Abstract: 830,024. Electric tests. MULLARD Ltd. April 30, 1957, No. 13722/57. Class 37. [Also in Group XXXV] In a touch-operated circuit in which a decrease in the resistance across touch terminals triggers a cold-cathode tube, the tube controls a circuit to give a succession of signals while the terminals are being touched and the interval between the signals is controlled by a timing circuit between the trigger electrode and cathode of the cold-cathode tube. In the electric fence control device shown, contact of an animal with touch terminals 13, 14 varies the trigger electrode potential of cold cathode tube V which triggers, operating relay A. Relay A shortcircuits the tube, extinguishing it, but condenser C1 maintains relay A operated for a period. A second contact discharges the condenser C3 through the primary of a pulse transformer while a third connects the touch terminals to the secondary of the pulse transformer and disconnects them from the supply. When C1 discharge relay A falls out and if the animal is still across the touch terminals, tube V triggers again when the potential on C2 has built up to the triggering voltage when the whole cycle is repeated. The same circuit may be used as a warning device without the pulse transformer (Fig. 2, not shown), the relay connecting a warning device to a completely separate circuit. In a modification of the electric fence arrangement described with reference to Fig. 3 (not shown), the secondary of the pulse transformer is connected in series with the supply and the touch terminals, a condenser being provided across both to prevent the pulses being fed back to the input.
