Patent GB-2231673-A (GB)
Title: Detecting DC in AC waveforms
Inventor: THOMAS LLOYD STANLEY
IPC: G01R19/25
Filed: 1990-04-06
Abstract: For detecting a DC component in an AC waveform, the positive and negative half cycles of the waveform are separated by rectifier means (2) and then squared by respective squaring devices (3 and 4) before being applied to an up/down accumulator (5). The output from the accumulator (5) is fed to comparators (6, 7). Each time the output from the accumulator (5) exceeds upper and lower threshold values the comparators cause the counter (10) to count and the accumulator (5) is reset. The count value of the counter provides an indication of the DC in the AC waveform. …<IMAGE>…

Title: Roping-down device
Inventor: SEEGER ALFRED
IPC: A62B1/08
Filed: 1990-04-18
Abstract: The device, for lowering a person to the ground, includes a shaft 2 forming a reel 5 for uncoiling band rope 6 secured at its upper end. The two end sections of rotatable shaft 2 form brake rotors 9 and 10 having wings 11 which rotate during rope uncoiling in chambers 31 partly or completely filled with particulate material to brake rotation. This brakes the descent of a person hanging from members 25, 26 on the reel. The material may be sand which may fill at least 70% of each brake chamber 31 and which may be drenched with oil. A manually adjustable friction brake (Fig. 3) may bring the reel rotation, and the descent of the reel and person, to a halt. <IMAGE>

Title: Adjusting ink-handling characteristics in continuous-jet ink-drop printer
Inventor: KEELING MICHAEL R
IPC: B41J2/12
Filed: 1991-10-16
Abstract: The viscosity of the ink is adjusted in response to the pressure at which it is delivered to the printhead, which pressure is in turn adjusted in response to the measured velocity of the droplets. As described, the printer may accept a printhead which has associated therewith a requirement for a particular droplet velocity and ink pressure. The velocity is measured by noting the passage of charged droplets past probes (59, 91) and the pressure is modified to achieve the specified velocity. Thereafter the ink is (if necessary) diluted to reduce the pressure to the desired pressure while maintaining the velocity. No viscometer per se is required. <IMAGE>

Title: Polar axis turning attachment for an existing fixed offset focus dish antenna
Inventor: COLLIER GLYN
IPC: H01Q3/04
Filed: 1991-11-22
Abstract: The conversion of a fixed offset focus dish pointing at one satellite to a multi-satellite dish satisfies growing interest in the provision of Multi Channel Television and Radio for the general public taking their signals from any selected stationary satellite across the horizon. Current practice in this area utilises a higher order of technology than that required for normal domestic use. The present attachment interfaces between the dish and a wall bracket, thereby enabling the dish to turn horizontally from horizon to horizon. The arrangement has been made simple for installation purposes so that either professional aerial riggers or, the amateur D.I.Y. person can install it. The arrangement includes a motor (1) and a gear box (3) which is connected to a worm wheel (5) by a reinforced flexible drive (4). The worm wheel (5) drives a larger gear (6) attached to a turning arm (B). <IMAGE>

Title: Differential drive for supercharged engine
Inventor: CROSSLEY IAN CHARLES
IPC: F02B37/10
Filed: 1992-01-16
Abstract: A supercharging compressor 6, for an i.c. engine, is driven via a planetary gear train, the planet gear carrier 1, of which is driven by the engine, and the ring gear 3, of which is driven by an exhaust driven turbine 4, via pinion 2. In an alternative arrangement (figure 2) speed increasing gears (8, 9) are interposed between the turbine and the pinion 2 and between the sun gear 5 and the compressor 6. At low engine speeds the compressor is able to be driven only by the engine at its maximum speed and hence its maximum boost pressure. The turbine can be used to maintain the compressor at maximum speed and maximum boost pressure, throughout the useful engine operating speed range. The turbine also provides part of the power to drive the compressor, and augments the power produced by the engine. It is stated that the turbine could be replaced by an electric, hydraulic or pneumatic motor. <IMAGE>

Title: Decorative pipe covers
Inventor: MOORE ANDREW THOMAS
IPC: B29C63/42
Filed: 1992-02-04
Abstract: Connection pipes (12, 14) for connecting a hot water radiator (10) to a water circulation system (16, 18) are encased in easily applied and removed decorative covers or tubes (22, 23, 34).

Title: Vehicle safety
Inventor: HOUNSELL JOHN OWEN
IPC: G01S17/931
Filed: 1992-10-08
Abstract: Indication of whether separation from a vehicle 17 ahead is safe or otherwise is given to the driver of a following vehicle 10 by transmitting two light beams 14 forwardly from that vehicle 10 onto an elongate retro-reflector 1 mounted across the back of the vehicle 17 ahead. The reflector 1 has a central, red zone 2, two amber zones 3 flanking the red zone 1 and two outer, green zones 4, and the angular directions of the transmitted beams 14 are varied by a unit 15 according to the speed of the following vehicle 10 so that their points of incidence on the reflector 1, and therefore the colours reflected, are dependent upon both the speed of the following vehicle 10 and its separation from the vehicle 17 ahead. The beam angle may be varied in accordance with steering of the following vehicle 10. The light transmitted may be infra-red instead of visible, in which case the reflector may be replaced by a detector actuating a transmitter of visible or infra-red light (if infra-red, the following vehicle 10 has a detector actuating an indicator and/or alarm). <IMAGE>

Title: Keyboard interface for clock and data signals
Inventor: CHEN CHENG-WEN
IPC: G06F3/023
Filed: 1992-11-12
Abstract: A keyboard interface checks the clock (3) and data (4) lines for a high potential which indicates that data may be sent from the keyboard (1) to the computer (2). If the clock is at low potential, the interface waits for a set period, governed by retry delay (10), before retrying. After three failures data is stored in a buffer (11) until the next transmit period occurs. If the data line is low, the three attempts are made consecutively without waiting for the set period to elapse, by reducing the delay to zero via a control signal. This allows data to be received by the keyboard without corruption. <IMAGE>
