The logic processing unit performs logic processing of an input data signal (111) on the basis of the first frequency-divided clock signal and outputs a burst timing signal (118). The digital filter is reset in response to the burst timing signal and converts output data from the logic processing unit (116) into a modulation baseband signal on the basis of the input clock signal. The modulation unit modulates the output signal from the digital filter. The high-frequency amplification unit performs burst- waveform processing of the output signal from the modulation unit for each time slot for time-division transmission on the basis of the burst timing signal (115). The second frequency divider outputs a second frequency-divided clock signal (125) obtained by frequency-dividing the input clock signal to reset the first frequency divider. <IMAGE>
Patent GB-2270363-A (GB)
Title: Flow control devices
Inventor: NASH JOHN VALENTINE
IPC: G05D7/01
Filed: 1993-08-16
Abstract: A fluid flow control device for minimizing the effects of fluctuating pressures on fluid flow rate has a variable restriction in the fluid path through the device arranged to produce a lesser restriction as the pressure difference between the inlet (22) and outlet (24) of the device increases, and vice versa. This first, variable restriction is formed by an inlet tube (40) and a blocking member (42). A second, constant restriction for the fluid flow is formed by the tube (40) and a parallel bore (34) through which the tube extends. A diaphragm (10) coupled to the blocking member (42) defines an upper, outlet chamber (18) and a lower chamber (20) connected to the flow path between the first and second restrictions. The pressure drop produced by the second restriction creates a pressure differential across the diaphragm (10) which is countered by a spring (30). Changes in this pressure differential cause the diaphragm (10) to move and so adjust the first restriction. <IMAGE>

Patent GB-942060-A (GB)
Abstract: 942,060. Gyroscopic apparatus. SPERRY RAND CORPORATION. Oct 21,1960 [Oct. 23,1959; Jan. 6, 1960], No. 36172/60. Heading G1C. In a system in which gyroscopic apparatus is controlled by a gravity-responsive device which is liable to be affected by lateral forces during turn of an aircraft,the control is modified by the joint effect of means responsive to rate of turn and angle of bank of the aircraft respectively. In Fig. 1 a compass card 42 is adjusted in known manner by a follow-up servomotor 34 into correspondence with a directional gyro 30 having a pickoff 41. A differential inductive device 35, the rotor of which is driven by motor 34 and the stator of which is supplied with signals from a flux valve compass 31, provides electrical signals which are applied to a precessing torque motor 40 to correct long term wander of the directional gyro. A tachometer generator 38 driven by motor 34 provides rate feedback and also applies an electrical signal representative of rate of turn to a transistor amplifier 45 the output stage of which is biased so that if the rate of turn exceeds a value determined by the setting of a potentiometer 56, a relay switch 60 is closed. If the angle of bank exceeds a predetermined value in either sense a sector switch 22 associated with a gyro vertical 10 closes. If both switches close, a relay 62 is energized to disable the erection control for the gyro vertical normally provided by liquid level switches 13 and 14 controlling torque motors 16,17. The opening of a switch 61 when quick erection is initiated prevents erection being disabled under these conditions. In a modification, Fig. 3 (not shown), signals proportional to rate of turn and angle of bank are added and applied to the input of an amplifier which operates a disabling relay if the sum of the signals exceeds a predetermined value. A similar arrangement may be used in a gyro-magnetic compass system for modifying or eliminating the control exerted by the magnetic compass on the gyro.
