Patent GB-1296292-A (GB)
IPC: G06F3/038
Filed: 1971-04-19
Abstract: 1296292 Measuring pulse width INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [30 April 1970] 26435/71 Heading G1U [Also in Division G4] In a pulse width measuring arrangement the control voltage (44) applied to a controllable single shot 42 is adjusted by a feedback loop to make the width of the single shot output pulse equal to the width of the input pulse (40), the control voltage then providing a measure of this latter pulse width. The leading edge of the input pulse 40 triggers the single shot 42. The single shot output 46 and the input 40 after inversion are fed to an AND gate 50, the resulting output pulses being fed to the inverting input of an integrator 56. Similarly the signal 40 and the signal 46 after inversion are fed to an AND gate 53, the output of which is fed to the non inverting input of integrator 56. The integrator output controls the single shot and is also fed to a display screen. By inhibiting either gate 53 or gate 55 the output may be made to track minimum or maximum signals respectively.

Abstract: 1296941 Freezing and melting congealed liquids; heat exchange heaters STAL REFRIGERATION AB 19 April 1971 [22 Jan 1970] 20118/71 Headings F4H and F4S Apparatus for breaking down aqueous jellylike solutions by freezing and subsequent melting includes a heat exchanger 1 having tubes 2 between headers 3, 4, around which tubes a coolant, e.g. NH 3 , is vaporized while absorbing heat from the tubes. In operation, when the tubes have been filled with the jelly-like solution, freezing is initiated and continues until a certain layer 12 of the solution has frozen on the inside of the tubes and a string 13 of unfrozen solution is formed along the tubes. The tubes and header 4 are blown free from unfrozen solution which goes to the container 8, air being supplied through conduit 16 and nozzles 17. The tubes are then heated and when the frozen solution has melted a valve 19 is opened in an outlet conduit 20 and the melted solution can flow out. A compression cooling plant is utilized for the freezing and melting of the solution. This plant comprises a compressor, an auxiliary condenser and two heat exchangers through which the coolant flows in series, said heat exchangers being arranged to operate alternately as an evaporator to freeze the solution and as a condenser to melt it. The solution is inserted through the conduit 10 and header 3 to the nozzles 11. Compressed air is supplied to a space 37 having a displaceable wall 38 provided with nozzles 39 with sealing washers 40. When compressed air is supplied, the wall 38 with its nozzles is pressed against the nozzles 11, the washers preventing air from entering the header 3.

Abstract: 1312128 Electronic timepieces JUNGHANS GmbH Gebr 30 July 1970 37017/70 Heading G3T In a timepiece comprising a known electronic drive circuit, e.g. Fig.2, for maintaining oscillations of an electro-mechanical oscillator thereof e.g. its balance wheel (or for winding a mainspring thereof), a switch is provided in the base bias circuit of a transistor amplifier Tr 11  instead of in the emitter/collector circuit thereof in order to interrupt the output drive current through drive coil L 2 . In operation of the drive circuit, current induced in a pick-up coil L 1  due to movement, thereof relative to permanent magnets, causes amplified current pulses from Tr 11  through L 2  thereby to maintain the mechanical oscillations. Either the coils or the magnets may be on the balance wheel (as illustrated), Fig.3 (not shown). In an embodiment, Fig.1 (not shown), a control transistor (Tr 2 ) is connected in series with the pick-up or control coil L and to the base of Tr 1 . Feedback oscillations due to the coupling of the two coils is said to be prevented by a capacitor C N . Self starting of the oscillatory circuit may be provided by suitable selection of component values. The switch may be coupled to the winding shaft of the timepiece whereby it is opened by axial withdrawal of the shaft and in addition may be coupled to a lever which is operable to stop movement of the balance wheel when the switch is opened.

Abstract: 1320327 Brakes DUNLOP HOLDINGS Ltd 23 Sept 1970 [27 Sept 1969 (2)] 47630/69 and 47631/69 Addition to 1251335 Heading F2F In a modification of the self-servo braking master cylinder of the Main Patent, the augmented fluid pressure generated on relative movement of the vehicle suspension parts is provided by a separate torque sensing unit 8 which generates fluid pressure when its piston 55 is moved by rotation of the brake pad holder 6 through link 7. The operation of the balance unit 3 is similar to that of the Main Patent. When pressure is received from pedal-operated cylinder 1 into chamber 12a, a balance member 19 therein is displaced to cut off registering channels 45, 46 with those 42, 43 in a sliding sleeve 17 and registers channel 45 with a third channel 39 in the sleeve. Fluid pressure from cylinder 1 is then fed to the disc brake 5a. Its torque reaction sensor 8 feeds increased pressure to the other brake 5b and also to chamber 13 of the cylinder. This lifts thrust member 22 and acts through pressure space 15 and various channels to the first disc brake 5a. Pressure is retained by non-return valve 41 and rises until balance is achieved when upward pressure on the balance member 19 equals that applied at the head of piston 20 by the cylinder 1, the relative areas determining the degree of increase. Excess pressure is relieved at radial channel 45 and channel 29 in the housing. A damping piston 23 is connected to the thrust member 22 to prevent hunting.

In operation, the leading end of the replacement web is cut to shape and is prepared with an adhesive and this zone of the periphery of the replacement reel is aligned with the magnetized element 21. When the running web is almost exhausted the replacement reel is brought up to a matching speed, and a splicing switch is actuated manually to activate a circuit which includes the proximity switches 26, 27. The element 21 actuates switch 26 when its angular position coincides therewith to cause roller 32 to press the web 52 on to the adhesive-carrying zone of the reel 50 to splice the two webs, the element 21 next activating the switch 27 to operate the cutter 34 to sever the old web. Thus the sequential operation of the roller 32 and cutter 34 is accurately controlled relative to the angular movement of the adhesive-carrying zone of the replacement reel.

Abstract: In a communications network, a network user communicates using a remote unit with another user via at least one base station. The communications network has a first base station having a first coverage area and a second base station having a second coverage area. In the situation where communication is not established between the second base station and the remote unit, in order to provide communication between the remote unit and the first base station when the remote unit is in the first coverage and simultaneously in the second coverage area, the first base station produces a first active communication signal at intended for the remote unit. The first base station transmits the first active communication signal from a first antenna. The base station delays the first active communication signal to produce a first delayed active communication signal and transmits it from a second antenna wherein the second antenna is oriented with respect to the first antenna such that the first active communication signal and the first delayed active communication signal fade independently as perceived by the remote unit. The first base station may measures a round trip delay of the first active communication signal in order to identify that the remote unit is located within the second coverage area.
