In a snap-action switch which may be thermally actuated the initial movement of the actuator 27, 28, Fig. 1, first moves a pair of links 9, 10 towards a dead-centre position at pivot 13 whereby the moving contact 8 moves endwise against the action of spring 11 and forcibly slides on fixed contacts 5 or 7 to break the contact weld and provide a cleaning action. After reaching dead-centre the links 9, 10 snap over in slot 30 of the actuator spring 27 whereby link 10 and spring 11 are brought to a dead-centre position so that a snap-action of links 10, 11 immediately follows to bring contact 8 against the opposite fixed contact 5 or 7. The link 9 has a flexible end held by a clamp 15 having an adjustable stop 23 to limit the movement of the link 9. Fixed contact 5 is adjustable in position by screw 6. A modification in which a tension coil spring replaces the leaf spring 11 is referred to. The actuator push-button 28 may be associated with an unspecified thermostatic device.

Filed: 1970-10-14
Abstract: 1332311 Regulating I.C. engines fuel supply; spray carburetters NISSAN MOTOR CO Ltd 14 Oct 1970 [22 Oct 1969] 48895/70 Heading F1B <SP>#</SP> [Also in Division G1] In an I.C. engine fuel control system, the fuel supply is cut-off when the velocity with which the throttle valve is moved towards its closed position exceeds a preset value. As shown, a throttle valve position detector 17, which may be a potentiometer type, Fig. 2 (not shown), an inductance type, Fig.3 (not shown), provides a signal which is differentiated in a shutoff signal generator 30, Fig. 4 (not shown), which provides an output to a controller 31 when the differentiated signal exceeds the preset value. The controller 31, Fig.6 (not shown), then provides a signal to shut - off a valve 15 in the fuel line. The controller also receives a signal from a fully closed throttle valve detecting switch 21 and a signal representing engine speed such that when the switch is closed and the engine speed exceeds a first preset value the controller 31 again provides a signal to shut-off valve 15, the valve 15 being re-opened when the engine speed falls to a second preset value lower than the first preset value. In the fuel injection system shown, a computing circuit 42 provides injection pulses of a width determined by engine speed, intake pressure, and engine temperature, the pulses being amplified in a controller 43, Fig. 7 (not shown), and applied to the injection valves 16. The output of the generator 30 is also applied to controller 43 to prevent the pulses being applied to the valves 16. The output of the controller 31 may also be connected to a valve for shutting the idle and lowspeed passage of a carburrettor, Fig. 9 (not shown).

Title: Seismic exploration
Inventor: VAIL PETER ROBBINS
IPC: G01V1/28
Filed: 1964-12-07
Abstract: 1,065,980. Geophysical prospecting. JERSEY PRODUCTION RESEARCH CO. Dec. 7, 1964, No. 49738/64. Heading H4D. In a seismic signal processing system the average amplitude in a portion of a seismic signal is determined and only indications representative of those parts of the signal portion which exceed the average amplitude are displayed. In the embodiment of Fig. 4 (not shown), the number of significant events, C, in the signal portion is determined by integrating the output pulses of a zero-crossing picker (68), and the cumulative amplitude, B, of the signal portion is determined by integrating the signal portion after rectification. The quotient B/C, i.e. the average amplitude, is obtained from a divider (76), is held, and is subsequently subtracted from the rectified signal portion, D, to give a " residual amplitude " signal F which may be recorded as a black.and-white or coloured trace of the combined variable-area-variable-density type on a photographic medium by means of a recorder similar to that disclosed in Specification 967,481. The mean energy, as represented by the area under the " residual amplitude " curve F, in a selected part of the signal portion may be determined by a further integration step (integration of curve F) and plotted on a map as a function of the seismic location (Fig. 8, not shown). For preparing a seismic section in which a plurality of traces are displayed side by side, the total energy in each seismic signal to be displayed is determined by rectifying and integrating each signal, and the gain of an amplifier (97) (Fig. 3) through which the signals are fed to the recorder is so adjusted that the mean amplitude in each amplified signal is the same. Alternatively, mechanical adjustments to the recorder may be made to accommodate the dynamic range of the several traces. In the embodiment of Fig. 10 (not shown), the average amplitude of a seismic signal portion is determined with respect to time rather than with respect to the number of significant events in the signal portion. In a modification, the signal processing is carried out by digital computer. Use of the invention enables disturbing effects due to variations in shot hole conditions or geophone coupling to be substantially eliminated from the seismic section. A recording of " residual cycle breadth," i.e. of those portions of a seismic signal in which the oscillatory period exceeds the mean period, may also be made.
