Patent GB-2252181-A (GB)
Title: A hydraulic drive system
Inventor: BEATER PETER
IPC: F15B11/16
Filed: 1992-01-21
Abstract: A hydraulic drive system comprises a hydraulic energy consumer, for example a hydraulic motor 1 for an excavator, connected to a pressure medium source. The consumer is actuated by a control valve 4 which carries out a throttling function in intermediate positions and the opening width of which is determined by a pressure difference formed in the control valve 4 and derived from a predetermined control pressure provided by a generator 11 and from the load pressure of the consumer. To limit the movement speed of the consumer, the control pressure is reduced in dependence upon the movement speed. The control pressure occurs in control pressure lines 7, 8 which lead to respective adjusting surfaces of the control valve 4 operating in a opening direction. An outlet line 16 branches off from the control pressure lines 7, 8 and contains a valve 15 which is loaded by spring force in the closing direction, carries out a throttling function in intermediate positions, and is controlled by a measuring device which detects the movement speed of the consumer by measuring the volume flow. The measuring device is formed by a restriction 12, arranged in the line 5 between the pressure medium source and the consumer, and by lines 13 and 14 which branch off from the lines at points upstream and downstream of the restrictor. The speed of the consumer may be detected electrically. <IMAGE>

Patent GB-921163-A (GB)
Abstract: 921,163. Controlling gas burners. E. KADING. Dec. 11, 1959 [Dec. 19, 1958], No. 42302/59. Classes 75 (1) and 75 (3). [Also in Group XXIX] A gas valve 2 mounted on the upstream side of a seating is opened by the bending of a bimetal strip 5, adjustably fixed at its lower end, when an electric current is passed through the strip. The stem 3 of the valve, which coacts with an adjustable stop 9, is guided by a spring 4 which also provides snap-action. When the valve is open the flow of gas cools the strip to such a degree that the force exerted by the strip is only just sufficient to hold the valve open whereby interruption of the electric current results in prompt closing of the valve. The electrical supply is derived from a transformer and also energizes an igniter for a burner controlled by the valve. In a modification the valve is mounted on the downstream side of the seat and actuated by a flexible wall of a capsule containing liquid or gas and a heating wire. The thermal element in either embodiment may be situated downstream of the seat, and lost motion may be introduced between the valve and stem.

Patent GB-2269078-A (GB)
Title: Frequency translation apparatus and method
Inventor: LAROSA CHRISTOPHER P
IPC: H04L27/233
Filed: 1993-07-15
Abstract: The present disclosure includes a discussion of a frequency translation apparatus for altering the effective frequency of the phase information of an input signal (115). The input signal (115) has a first phase ( theta  (t)) and a first frequency (fi). The phase of the input signal is extracted and digitized at a second frequency (fo), forming a second N-bit digital phase signal ( theta  min  (t)) (311). The frequency translation apparatus generates a third digital phase signal (319) which approximates the difference between  theta min  (t) and  theta  min (t). Then, the frequency translation apparatus (313) combines the second digital phase signal and the third digital phase signal, forming a fourth digital phase signal (307) substantially approximating the first phase signal. <IMAGE>
