Patent GB-2060312-A (GB)
Title: Improved digital on video recording and playback system
IPC: H04N9/44
Filed: 1980-10-10
Abstract: Digital data is recorded as luminance level in synchronism with the colour subcarrier signal in one horizontal line period adjacent a constant (black) luminance line within the vertical banking interval between adjacent fields of video information on a video disc. The arrangement facilitates separation of the digital information by generating a difference signal between the data line and the black line using the comb filter already provided in the system. The digital data represents field number and type of program content and is used by a microprocessor controller to provide player features such as locked groove detection, program elapsed time display, and end of program indication.
Patent GB-2061146-A (GB)
Title: Ganging workpiece dimensions
IPC: G05B19/23
Filed: 1980-10-20
Abstract: A numerically controlled machine tool 10 has a probe 15 for measuring a workpiece surface S. The probe is movable relative to the workpiece by a programmed control unit 100. For the purpose of a measuring operation the unit 100 is programmed to move the probe toward the surface S to attain a position, which is known relative to a datum CL and in which the probe is still clear of the surface S, whereat the unit 100 outputs a signal 114 to a counter 204. The latter is provided in a second control unit 200 and constitutes a second measuring means that measures any further movement of the probe. When, during such further movement, the probe engages the surface S, the probe outputs a signal 24 connected to stop the counter. Thus the content of the counter at the instant of the signal 24 is a measure of the position of the surface S in terms of its distance from the known position. <IMAGE>

Title: Battery charging apparatus
IPC: H02J7/00
Filed: 1981-04-13
Abstract: Battery charging apparatus includes means for terminating the charging process in dependence on a comparison of the battery voltage in adjacent time-intervals. A pulse generator (23, 25) produces a control signal with a pulse frequency dependent on the battery voltage. An oscillator (50) feeds the pulses to respective counting means (32, 33) during the time-intervals. A circuit (21) amplifies the difference between the reference voltage (11) and the battery voltage the difference being inverted so that the frequency of the VCO (23) decreases as the battery voltage increases. This prevents the counter (25) overflowing at high battery voltages. A comparator (36) compares the counts from adjacent time-intervals and provides a signal to stop charging when said counts are equal. <IMAGE>

Title: Monopulse radar
Inventor: WELSH JOHN
IPC: G01S13/44
Filed: 1981-06-24
Abstract: In an air-to-surface radar ranging system employing a conventional four-element monopulse beam-split serial array (11) followed by a monopulse comparator (15) to extract sum, difference and nonsense channels, rolling of the aircraft and/or across-track sloping of the ground causes ranging uncertainties due to the left and right hand halves of the beam-split system "striking" the ground at different heights. It is found that when the left and right hand elevation difference signals are subtracted the result is a signal of magnitude proportional to the slope of the across-track surface and of polarity indicative of the slope direction. It is also found that this subtracted signal is given by the nonsense channel signal. <IMAGE>

Patent GB-2083993-A (GB)
Title: An irrigation device
IPC: A01G25/16
Filed: 1981-09-09
Abstract: The irrigation device comprises a receptacle (5) supplied with water. A float (6) with a siphon (12) is located above outlet (13), one branch pipe (11) of said siphon extending through a portion (10) in the bottom of the float. The pipe (11) carries at its lower open end a valve (7) which may close tightly against a surface (8) in the bottom of the receptacle (5). A closing pipe (9) projects from the surface (8) about the pipe (11) and forms together with the bottom portion (10) of the float a siphon connection between the receptacle (5) and the outlet (13). Within the receptacle (5) the water raises the float until the valve (7) closes against the surface (8), and the water rises beyond the top rim of the float until the water within the float has reached a level (C-C) at which the weight of the water with the float surmounts the buoyancy in the receptacle (5). The connection to the outlet (13) is thus opened, and the water is quickly sucked out through the siphon connection at the underside of the float and produces a sucking effect within the siphon (12) so that the float (6) is emptied. Clogging deriving from deposits and a slow leaking out of water through the siphon are avoided due to the quick irrigation and to the fact that stagnant water is never present at the elbow of the siphon. <IMAGE>

Title: Power drive line having a wide range of speed ratios
IPC: F16H15/50
Filed: 1980-05-19
Abstract: A power drive line in which a continuously variable, nutating traction drive transmission unit (16) is combined with a single planetary gear set (84, 86 and 88) to provide two forward modes and a reverse mode of drive line operation. A pair of transmission unit input shafts (18 and 20) are alternately coupled to a power input to the overall drive line. In one forward mode, the planet gear (86) is driven by the sun gear (84) to rotate the ring gear (88) in a relatively wide low speed range of speed ratios. In another forward mode, the transmission body (52) carrying the planet gear (86) is connected to be driven directly by the drive line power input to effect a relatively high range of output speeds for a given input speed. In the reverse mode, the body (52) carrying the planet gear (86) is held against planetary movement so that the planet gear (86) operates as a reversing idler between the sun gear input (84) and the ring gear output (88).

Title: System for correcting flexure of the knife of an automatic cutting machine
IPC: B26D5/00
Filed: 1982-01-19
Abstract: To correct flexure of the knife of an automatic machine used for cutting fabrics and other flat materials, flexing of the knife 1' is detected by a digital sensor 28 providing a signal indicating only the presence of flexure and its direction. The digital information is applied to a computer or processor 2' which provides a flexure-correcting signal controlling the orientation of the knife with respect to its path. Sensors 5', 6' feed back knife position and speed. The required correction is computed in conjunction with these signals and information concerning the properties of the material to be cut. The computer 2 may also be programmed to produce preventive corrections based on characteristics of the material to be cut, etc. and also to initiate automatic sharpening of the knife. <IMAGE>

Title: Controlling contrast
IPC: G03F5/24
Filed: 1982-03-19
Abstract: A densitometer for the control of the contrast in the reproduction of a half-tone picture, by means of a main exposure and an auxiliary exposure, initially measures the density in both the lightest and the darkest field of the picture by scanning across the picture, a memory (1A, 1B) remembering both the greatest and the smallest value of the reflection, and the ratio of the auxiliary exposure to the main exposure required in the reproduction being calculated after the scanning. The densitometer comprises a photodiode and at least one amplifier, said amplifier communicating with an analog-digital-converter, the outlets of which feed both a memory registrating the lowest reflection value and a memory registrating the highest reflection value. After a scanning and through the assistance of an operator, these two values may be transmitted to a calculating unit adapted to calculate the exposure ratio. The densitometer may scan at a velocity of 20-200 cm/sec.
