Title: IC engine electronic ignition timing control
IPC: F02P5/155
Filed: 1979-02-15
Abstract: Pulses generated in a pickup 10 synchronized with the engine crankshaft are fed to a circuit 15 for generating a voltage proportional to the desired advance and to a phase locked loop 20 which is adapted to generate, at its output, a ramp synchronized with the input pulses, the ramp output and proportional voltage being supplied to a comparator 17, the output of which generates firing pulses which are advanced as a function of engine operation for use in the electronic ignition system.

Patent GB-2023811-A (GB)
Title: Testing safety devices
IPC: G01M99/00
Filed: 1979-02-19
Abstract: Apparatus for use in testing safety devices employing one or more photo- electric beams (either visible or invisible) fitted to industrial machinery, measures the interval of time between the interruption of the beam(s) and the moment when the moving parts of the machine may be deemed to be at rest. An electro-magnetic transducer is connected to the moving parts of the machine and supplies a speed signal to a logic circuit via an amplifier. A second amplifier accepts a signal from a photo- electric sensor and applies it to the logic circuit. When the logic circuit senses both signals it passes pulses one millisecond apart to a counter and continues to do so until the speed signal indicates that the moving parts of the machine are at rest. The number of pulses passed is then displayed on a digital readout, indicating the elapsed interval in milliseconds. <IMAGE>
Patent GB-2016833-A (GB)
Title: Protection of electrical power supply systems
IPC: H02H3/40
Filed: 1979-02-27
Abstract: A distance relay determines the impedance of a line section by effectively calculating the ratio of the Fourier transforms (evaluated for a particular time interval T1-T2 and frequency  omega e) of (i) the line voltage Vr and (ii) the current that would flow if the line voltage were equal to Vr during the interval T1-T2 and equal to zero at all other times. This second quantity cannot be sensed directly but can be derived from the Fourier transform of the actual line current Ir. The digital relay described separately evaluates the resistive and reactive components of the impedance for both phase-phase and phase-earth faults, repeating the evaluation continuously for new periods T1-Y2.

Title: Low-frequency supplementary information transmitting arrangement for a digital data transmission system
IPC: H04J3/12
Filed: 1979-08-09
Abstract: A supplementary information transmitting arrangement for a digital data transmission system in which the supplementary information is a low- frequency wave and is transmitted simultaneously with the incoming digital data signal. The transmission device 50 modulates the "high" level parity of the incoming digital data signal by the supplementary information conveying low-frequency wave and the reception device restores the low-frequency wave from the outgoing resulting digital signal from the transmission device. To this end, a supplementary predetermined word is inserted in the outgoing digital signal or the redundancy of a particular n-binary digit to m-ternary digit code is used. In last case, the transmission device 50 comprises a transcoder 57 transmitting the outgoing resulting digital signal to a "high" level parity detecting circuit 60 and a comparing circuit 63 which compares the "high" level parity of the outgoing signal and a predetermined parity fixed to the phase of the low-frequency wave so as to control the selection of the m-ternary digit word in the transcoder 57. <IMAGE>

Title: Bicycle rolling road exercise machine
IPC: A63B69/16
Filed: 1981-05-18
Abstract: This equipment enables any type of adult cycle to be converted quickly into a static exercise machine and provides rollers acting on the back wheel of the cycle thereby creating the rolling road whilst the front wheel remains stationary on the floor. Stability for the rider is achieved by clamping the bike immediately behind the bottom bracket using a hinged clamping bracket to allow variation in wheel size to be accommodated. The clamping bracket is attached via a hinge pin to a telescopic support arm which is free to move within a sliding support bracket, thereby accommodating variations in frame height. The sliding support bracket utilises the parallel beams supporting the rollers as guide rails for location enabling it to slide into the correct position dependent on the cycle frame size. Once clamped in position the bracket is able to transfer the out-of-balance forces of the rider through the beams to the stabilizing feet. <IMAGE>
