Patent GB-2215154-A (GB)
Title: Power switch control circult, e.g. for television apparatus
Inventor: LUZ DAVID WARREN
IPC: H03K4/68
Filed: 1989-02-24
Abstract: A power switch control circuit e.g. a television deflection apparatus includes a deflection winding 81 or other inductance coupled to a retrace capacitance 80 to form a retrace resonant circuit. A power transistor switch 87 is coupled to the retrace resonant circuit for generating alternating current in the retrace resonant circuit. The power transistor switch 87 energizes a primary winding 53a of a flyback transformer 53 that supplies a first voltage across a secondary winding 53b of the flyback transformer 53. The first voitage is coupled to an inductance 82 for forming and upramping current in the inductance 82. The upramping current in the inductance 82 is coupled to the base electrode 93 of the power transistor switch 87, causing the power transistor switch 87 to be conductive during the second half of trace. A second switch 84, that is responsive to a switching rate input signal, couples to the base electrode 93 of the power transistor switch 87 a negative supply voltage VNEG that turns off the power transistor 88 to initiate the retrace interval. <IMAGE>

Title: Servo-controlled expansion valve arrangements for a volatile fluid
Inventor: VALBJOERN KNUD VAGN
IPC: F25B41/06
Filed: 1990-07-09
Abstract: A servo-controlled expansion valve (20) for a volatile fluid, particularly for use in electronically-controlled injection of refrigerant in the evaporator of refrigeration installations, comprises a main valve (21) which is actuable by a controlled pilot valve arrangement (6) by means of a servo arrangement in which the volatile fluid serves as an actuating pressure medium. When the pilot valve arrangement is actuated by such fluid acting as a pressure medium, there is a danger that fluid will evaporate in the operating chamber of the servo arrangement. The compressibility of the vapour can lead to oscillations which also cause the main valve (21) to oscillate. Those oscillations are to be avoided. For that purpose, the servo arrangement (24) is, according to the invention, thermally connected to the outlet side (2) of the main valve (21). <IMAGE>

Title: Removing noise induced artifacts from a repeating complex waveform
Inventor: BELLIN HOWARD THEODORE
IPC: A61B5/308
Filed: 1992-04-27
Abstract: A system for processing a repeating complex waveform, e.g. an ECG signal, removes or reduces a significant portion of artifacts and other noise. The system produces at least two waveforms (A and B) relating to said complex signal, and employs a phase detector (40) to isolate artifacts (C) eg by subtraction of the waveforms (A and 8), which are then used in processing the ECG waveform (70, 75) for display. The two waveforms (A and B) are relatively displaced by a whole multiple of the waveform period using a delay 20, or one of them is stored in memory. The waveforms are summed (65) and the artifact signal (C) is subtracted from the sum (D). The resulting clean signal (E) makes accurate diagnosis of pending patient condition faster and more reliable. <IMAGE>
