Title: Halyard stopper
IPC: F16G11/10
Filed: 1980-11-03
Abstract: A halyard stopper has a locking assembly comprising a spring pawl (27) pivoted within at (28) within a U-section rocker arm (16) and movable between a locking position in which it grips a halyard or other rope (52) (Figure 3, not shown) and a release position. As a shoulder (48) of the lever (18) on raising of the latter clear the free end of the arm (16), the arm rotates upwardly about (10) under the action of a torsion spring (42). This rotates the paw (27) clockwise against the action of its spring (46) as it engages an abutment (26). As a result, the pawl (27) is lifted away from the halyard with little movement in the direction opposite to that of the force acting on the halyard. Should the arm (16) become jammed and the force of the spring (42) be insufficient to lift it clear of the halyard, an arm (54) of the lever (18) will engage the underside of the arm (16) and so raise the arm. <IMAGE>

Title: Grinding
IPC: B24B41/06
Filed: 1981-03-02
Abstract: The invention is concerned with the machining of longitudinal ball tracks into the inner joint members of universal joints. A workpiece 84 for the joint member is clamped in position by clamping mechanism of a spindle mechanism (22), by which a split collet (38) is opened into interior engagement with the workpiece, pulling the workpiece onto an annular base surface (32) and into engagement with internally curved surface positions (35) provided by resilient fingers, which engage with the exterior surface (82) of teh workpiece. In this position, the longitudinal axis of the joint member coincides with the longitudinal axis of the spindle mechanism. The spindle mechanism (22) is carried by an arm (18) so as to be moved arcuately about a further axis (LA3) relative to a rotating grinding wheel (14) so that the grinding wheel effects machining of one of the ball tracks of the member. Subsequent to retraction of the grinding wheel, the spindle mechanism (22) is rotated about its longitudinal axis (LA1) to present to the grinding wheel (14) another surface portion of the joint member, and another ball track is machined into the workpiece. <IMAGE>

IPC: G11B20/14
Filed: 1982-07-06
Abstract: A data separator for providing data and clock information derived from a floppy disk to a controller includes a synthetic oscillator phase- locked loop which adjusts the phase of the derived clock, thereby to tend to position data inputs within the central portion of their associated half-bit slots. The center frequency of the synthetic oscillator may be modified 30 in accordance with prior phase adjustments to compensate for variations in the speed of the floppy disk drive.

Title: Combined anti-wheel spin and anti-wheel lock control system for a motor vehicle
Inventor: BURCKHARDT MANFRED
IPC: B60W10/18
Filed: 1982-07-07
Abstract: A design of a propulsion control i.e. anti wheel-spin and propulsion torque reduction system for vehicles equipped with a four-channel anti- wheel lock system is given, permitting a combined system on the vehicle, at an additional cost which is only small in comparison with that of an anti-lock system alone, this propulsion control system utilising an auxiliary pressure source 41 and including the safety system which is required for monitoring its operation. The basic design of a propulsion control system is integrated with the anti-lock system. Wheel speed-sensors (17, 18, 19 and 21), brake-pressure regulating valves (26 and 27) of the driven vehicle wheels (14 and 16), the pump (33) associated therewith which returns dumped brake fluid upstream of the values (26 and 27), provided as components of the anti-lock system, as well as that signal input stage (53) of this system which receives the signals from the wheel speed-sensors, are utilised at the same time, as appropriate, as components of the propulsion control system (10). The respective safety circuits (37 and 52) of the anti-lock system (11) and of the propulsion control system (10) are designed in a manner such that, in the event of an operating fault in the anti- lock system (11), the propulsion control system (10) is switched off, at the same time, while only this latter system is switched off in the event of its operation becoming faulty. A warning indicator (39) is provided. <IMAGE>

Title: Focus correction
Inventor: GROVES PHILIP RANGECROFT
IPC: H04N5/217
Filed: 1982-09-09
Abstract: Optimum magnetic focus correction at a matrix of points in the field of a camera tube is determined so that interpolated values may be applied throughout the field in service. A high frequency component is extracted (22) from the video signal from each in turn of 15 x 15 test patterns on a chart, the peak to peak HF amplitude being measured (24), sampled and stored (26) for comparison, as the focus correction signal (28) is adjusted in steps. This optimum correction signal for each pattern is converted to digital (30) and stored in RAM (34). To provide interpolated correction as the working point moves between the positions of adjacent patterns, the two values read from the RAM are converted to analogue in a D to A converter (36) where the digital values are multiplied by reference voltages which follow triangular or other waves in antiphase between a fixed value and zero, the sum of the two products controlling the focus correction (28) via modulator (16). <IMAGE>
Patent GB-2127240-A (GB)
Title: Power control devices
Inventor: ALVERS ARTHUR FRANCIS
IPC: H02H9/00
Filed: 1982-09-14
Abstract: The device initially applies a low voltage to equipment (such as heating devices utilised in injection moulding machines) and after the elapse of a predetermined period of time causes full voltage to be applied to the equipment. On closing a main switch M/S a timer T is started and a temperature control unit T.C.U. is energized to close a switch S7 thereby causing a relay A to close a switch S3 whereby a reduced voltage (e.g. 90 volts) is applied to an output terminal t1 via a power regulating unit P.R.U. which may include triacs. When timer T times out it closes switch S8 to energize relay B thereby opening switches S1 and S4 to isolate the PRU, and closing switches S2, S5, S6 to apply full mains voltage to the output terminal t1. <IMAGE>

Title: Television Transmission Systems
Inventor: BECKLEY JOHN CHRISTOPHER
IPC: H04N7/00
Filed: 1983-03-14
Abstract: A wide band frequency modulated DBS signal of the type having time sequential compressed chrominance and luminance components is converted into a second television signal for transmission via a medium with a lower bandwidth e.g. cable. The wide band signal is received by an aerial 1, frequency converted in a down converter 2 and applied to the input 4 of the conversion unit. The conversion unit has a tuner 5, i.f. stage 9, 10 and a frequency demodulator 11 to produce baseband video which is applied after de- emphasis at 12 to a modulator 27 where the video is amplitude modulated onto a vision carrier from an oscillator 28. The modulated carrier is applied through a vestigial sideband filter 29 and an adder 30 to the output 31. Sound/data bursts present in the DBS signal are recovered in stage 13 and processed in unit 14 where the sound/data bursts are expanded to occupy approximately one line period at a bit rate which is an integral sub-multiple of the bit rate for the sound/data bursts in the received DBS signal. The expanded sound/data and clock frequency are digitally modulated in modulator 32 onto a sound carrier from oscillator 33, the modulated sound carrier being applied through bandpass filter 34 and the adder 30 to the output 31. The output 31 connects the signal to the cable distribution system. <IMAGE>
