Patent GB-2088666-A (GB)
Title: Electrical filter circuits and methods of filtering electrical signals
IPC: H03H19/00
Filed: 1981-11-26
Abstract: Electrical filters are described which are akin to digital wave filters but which employ analogue computation. The filters are made up of multiport adaptor cells incorporating unit delays, and each cell computes reflected signals at ports from incident signals by using analogue techniques to solve equations relating incident and reflected signals. The adaptor cells use capacitors coupled by switches operated in two phases. For example, in first phases, capacitors C1 to C3 receive voltages corresponding to incident signals, and capacitors C4 and C5 receive voltages representing differences between incident signals. In second phases reflected signals corresponding to additions, subtractions and multiplications of the voltages held by the capacitors are derived by reconnecting the capacitors. Each cell is part of a unit element or represents an inductance or capacitance as determined by a feedback network in which in first phases the reflected signal at one port is stored in a capacitor C6 and used, in the next phase, as the incident signal at that port. <IMAGE>

Abstract: A knitting machine has at least one pair 5 of needle beds, carriages 4,2,3 operating one after the other and for controlling the machine, fixed setting elements arranged in sections 5', 8', 10, 11 and a minicomputer control unit 25. Associated with each setting element section 5', 8', 10, 11 is an initiator 20-24 which is disposed upstream of the associated setting element section in the direction of travel of the carriages and is operated by each carriage; each initiator is connected via an input line 27-31 to minicomputer 25; one group of output lines 41 of the minicomputer 25 is connected via individual amplifiers 43-50 and a further group of the output lines 42 is connected via group amplifiers 77', 77'', 77''', 77 to 80 to the setting element sections 5', 8', 10, 11 combined in a matrix circuit. The influence of disturbing pulses on the input lines 27-31 of the minicomputer 25 is reduced to a minimum by causing the computer to repeatedly interrogate the same input line for very short periods (2 mu s) until a signal is detected, before repeatedly interrogating the next line in the sequence. <IMAGE>

IPC: A63B51/12
Filed: 1984-04-13
Abstract: A device for adjusting the tension of the strings of a tennis racket, comprises a movable adjustment bar 22 provided in the racket throat. The bar has multiple string holes 221 with the string 222 going through them. Preferably a screw nut 23 is inserted at each end of the adjustment bar, each screw nut engaging a screw bolt 24 which is hinged on a bolt seat 25 which in turn is mounted on the racket frame.
