Patent GB-978991-A (GB)
Title: Improvements in or relating to data imprinting mechanisms
Inventor: WALLACE STANLEY ROBERT
IPC: B41L5/14
Filed: 1960-12-14
Abstract: 978,991. Date and time printing apparatus. LAMSON PARAGON Ltd. Dec. 8, 1961 [Dec. 14, 1960], No. 42951/60. Headings B6A and B6D. An autographic register has printing mechanism to record the time at which an entry is made, a switch operative during the stationery feeding cycle to initiate a time delay cycle, and means operative at the end of the time delay cycle to prevent further feeding of the continuous stationery and to prevent further printing operations from being effected. The web of stationery is fed along the top of the register by feed discs 2 which are driven through a gear 5 and a toothed segment 4 by an operating lever mounted on the shaft 3 carrying the toothed segment. The time is indicated by a series of type wheels 6 located below the stationery web and which are raised by cam means when the feed discs 2 are rotated so as to press the web against a platen 8 and print the time thereon. Provision is made to prevent fraudulent operation of the machine by movement of the operating lever sufficiently far to effect a printing operation but not far enough to advance the web. To this end a microswitch 9 is positioned in the path of the segment 4 and is closed as soon as the latter begins to rotate, thereby energizing a solenoid 15 and actuating a time delay unit 14. The solenoid 15 withdraws a stop 18 out of the path of the segment 4 so that the latter can make a complete rotation and effect not only printing of the time but also feed of the stationery web. When the segment has returned to its initial position the switch 9 is opened and the solenoid 15 de-energized, the stop 18 being returned to the full-line position by a spring 17. If the movement of the operating lever is not completed so as to feed the web, the microswitch 9 remains closed and after 20 seconds the time delay unit opens a pair of contacts 19 in the circuit of a relay controlling a pair of contacts 11 in the circuit of the solenoid 15. The contacts 11 are thereby opened and can be reclosed only by means of a plunger 21 access to which is impossible without opening the machine casing; simultaneously a light on the side of the register, which is normally on during operation of the machine, is extinguished. When the contacts 11 are open the solenoid 15 cannot be actuated and the stop 18 remains in the path of the segments 4 so as to prevent further rotation thereof. Specifications 840,355 and 933,338 are referred to.

Title: Improvements in or relating to turbojets with afterburner and variable area nozzle means
IPC: F02K1/16
Filed: 1964-10-22
Abstract: 1,084,957. Fluid-pressure servomotor systems. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Oct.22, 1964 [Oct.23, 1963], No.43059/64. Heading G3P. [Also in Division F1] The fuel flow C' to the reheat chamber of a gas turbine jet propulsion engine having a variable area nozzle is controlled by a bellows 15 mounted within a chamber 13 subject to compressor outlet pressure P 2  and including an adjustable leakage 14. The bellows 15 operates on the fuel metering device 50 through a variable leakage ball type follower device 52 and a servo-control valve 51. The position of the fulcrum 54a of lever 54 is set by the pilot's lever (9b), Fig. 1 (not shown), which also controls the opening of the variable area nozzle. To prevent overheating when the nozzle reaches the fully open position a further leakoff 18 is opened by an obturator 53a responsive to mechanical, electrical, hydraulic or pneumatic means sensing the fully open position, thus reducing the fuel flow C'. In a modification applicable to a multi-spool engine, Fig. 5 (not shown), the opening of leak-off 18 is controlled by a flap valve (39, 45) which is opened by a governor (44) when the speed of the low pressure rotor drops below a predetermined value at full nozzle opening.

Filed: 1969-09-05
Abstract: 1278957 Tuning monitors AUDITS OF GREAT BRITAIN Ltd 4 Dec 1970 [5 Sept 1969] 44139/69 Heading H3Q A tuning monitor apparatus for a receiver comprises a tuner 5 receiving a signal derived from the local oscillator 2 and tunable over a range of frequencies stepwise by an applied stepped electrical signal, e.g. a staircase signal from scan generator 8 controlled by a lowfrequency oscillator 10, and a sensing arrangement for indicating which step corresponds to the received tuned frequency. In operation, the tuner may be driven by a stepping motor but preferably a varactor or varactors in the tuner 5 are controlled by an applied staircase waveform signal. Clock pulses from 10 are applied to bi-stable dividers and AND gates (15, Fig. 2) in the scan generator 8 for producing control signals for switching transistors (17, Fig. 4) serially connected to resistors (18) with taps which are sequentially connected to a common output for producing the staircase signal. When the tuner is correctly tuned, a D.C. output at 7 may be applied to a switching transistor at input of the oscillator 10 to switch it off. The D.C. output is also used to control a recording apparatus 11 indicating the step, i.e. the frequency of incoming signal.

Abstract: 916,527. De-veining prawns and removing them from their shells. LAPEYRE, F. S., LAPEYRE, J. M., LAPEYRE, A. C., LAPEYRE, F. H., LAPEYRE, E. M., and LAPEYRE, E. M.. [trading as PEELERS CO.]. Dec. 28, 1960 [Oct. 27, 1960], No. 44457/60. Class 28 (2). Edible meat is recovered from crustacea by introducing fluid under pressure into the space within the shell while it is held substantially immovable. Prawns are laid side by side on a stainless-steel belt 20 driven continuously from a cam-shaft 32 carrying cams which control the various operations carried out on the prawns as they are carried along on the belt. A pivoted member 47 pcsitions the prawns for de-veining by a hollow plastic tube 58, guided into the prawn by shaft 57 and member 59, to sever the vein from the meat and shell. Vacuum chamber 52 is connected to tube 58 to withdraw the severed vein and washing water is supplied between shaft 57 and member 58. During deveining the prawn is held by a member 63 which also positions member 59. The de-veined prawns are pushed across belt 20 by a pivoted member 48 into meat ejection position. A member 46a holds the prawn with its tail end overhanging the belt 20 to receive needle 70 through which pressure is applied to expel the meat.

Title: Improvements in and relating to controlled rectifier arrangements
IPC: H03K17/72
Filed: 1964-11-04
Abstract: 1,063,127. Semi-conductor circuits. LE MATERIEL ELECTRIQUE S.W. Nov. 4, 1964 [Nov. 19, 1963], No. 45026/64. Heading H3T. [Also in Division H2] A controlled rectifier R in a converting circuit is controlled by transistors T1, T2 of opposite conductivity types which are operated as switches by a control unit 5. The output of a high frequency generator 2 is rectified by two bi-phase rectifiers (D1, D2 and D3, D4) to give positive going and negative going pulse trains, one of which is applied to the control electrode of the controlled rectifier R through whichever transistor is switched on by the control unit 5. Because the generator 2 has a frequency much higher than the frequency of the main current in the controlled rectifier, fast rising firing pulses are obtained without using special pulse transformers. For series or parallel operation of controlled rectifiers each rectifier has its own secondary windings on the output transformers of the generator 2 and control unit 5. With the invention a conducting controlled rectifier has a continuous firing signal applied, and a non- conducting one has a continuous negative trigger signal to reduce the possibility of spurious firing.

Filed: 1964-11-09
Abstract: Triarylboranes are prepared by reacting an aryl magnesium bromide or iodide with a boron halide in the presence of an organic ether to give triarylborane and magnesium halide etherate; adding a hydrocarbon solvent for triarylborane in which magnesium halide is insoluble; heating to cleave the magnesium halide etherate and strip the ether, and separating the triarylborane as a hydrocarbon solution from the precipitated halide.  The hydrocarbon solvent has a boiling point higher than the decomposition temperature of the magnesium halide etherate.  The hydrocarbon may be stripped from the final solution and the triarylborane recrystallized from a lower alkane, e.g. n-hexane. The preparation of triphenylborane from boron tri-fluoride ethyl etherate and phenyl magnesium bromide in tetrahydrofuran is described wherein xylene is the solvent added. Other specified aryl groups are tolyl, xylyl, ethylphenyl and naphthyl.  Other specified boron halides are BF3, BCl3, BBr3, BI3, BBr2I and the tetrahydrofuran and dioxane etherates of BF3.
