54	Fail-safe throttle control	US3791366D	1971-12-10	US3791366A	1974-02-12	MAC MILLAN C
The invention relates to a fail-safe throttle control mechanism which is positioned between an accelerator pedal of a motor vehicle engine incorporating a fuel injection system and includes a linkage assembly which extends from the accelerator pedal to the fuel injection control system and has combined therewith a sensing mechanism for disengaging the accelerator pedal from the fuel injection control system so that the engine of the motor vehicle can instantly return to an idle condition irrespective of any impairment in the control linkage or blockage of the accelerator pedal. There are disclosed various embodiments for achieving this fail-safe operation of fuel injection control mechanisms.
55	Vehicle engine fuel control accelerator override	US3731663D	1971-01-08	US3731663A	1973-05-08	HOLLINS J
Apparatus for controlling the position of an accelerator control element of a vehicular engine when the mechanism conventionally employed for moving the same has frozen. The apparatus includes a resilient member in a first kinematic train between said element and the accelerator pedal or like element usually employed by the vehicle operator to regulate the engine speed. The resilient member is connected to said element directly or through nonfreezable components. A return resilient means which is substantially weaker than the resilient member biases the accelerator control element to an idle position. A second kinematic train is so arranged that when actuated by the vehicle operator it will positively move the accelerator control element toward its idling speed operating position. In normal use a force is applied through the first kinematic train and resilient member to move the accelerator control element in an engine speed-up direction while storing up energy in the return resilient means whereby as such force is reduced the engine speed will slow down. If the control element or any part of the first kinematic train is frozen the operator can, through the second kinematic train move the control element against the bias of the resilient member toward its idling speed operating position and in this manner either slow down the engine to idling speed or regulate it to any speed between idling and the speed corresponding to engine speed at which the first kinematic train was frozen. The resilient member is weak enough to be elastically deformed by the force applied by an operator through the second kinematic train.
56	Apparatus for forcibly closing an engine throttle valve	US3722492D	1970-12-23	US3722492A	1973-03-27	SHIBATA Y
An apparatus for forcibly closing a throttle valve in a suction passage of an internal combustion engine, the throttle valve being movable to open and close by an acceleration operation member such as an acceleration pedal or the like. The apparatus for forcibly closing the throttle valve is mounted on one side of the throttle valve, and is operated when the throttle valve is not closed and the acceleration operation member is released from operation. The apparatus for forcibly closing the throttle valve comprises an electromagnetic solenoid with a core which is advanced with rotation when the solenoid is energized, there being a first detecting switch which is closed when the acceleration operation member is released from operation and a second detecting switch which is closed when the throttle valve is in its open position, the two switches being interposed in series in an electrical circuit containing the solenoid and an electric source.
57	Pneumatic annunciator system	US3720182D	1971-11-18	US3720182A	1973-03-13	HARRAH R
As a representative embodiment of the present invention, pressure-responsive indicators are coupled to suitable transducers monitoring selected operating conditions of an industrial machine. Pneumatic controls are arranged for providing first pneumatic signals when these operating conditions reach a predetermined value and producing second pneumatic signals should any of the operating conditions vary from its selected range. Other pneumatic controls are uniquely arranged for responding to the second signals to produce a brief third pneumatic signal which is effective to operate only the associated indicator while the other unaffected indicators are positively retained in their safe indicating positions. The indicators of the present invention are adapted to be stacked together and respectively include a number of passages adapted to coincide with the matching passages in the other indicators. One set of these passages in each indicator can be isolated from the other set by orienting the indicator in one position in relation to the other indicators. A second set of these passages is coupled to an alternately-positionable spool in each indicator which is uniquely arranged to select which of the passages in this other set is to be coupled to the pressure-responsive element in that indicator.
58	Control system for fuel control under starting and excessive speed conditions in an internal combustion engine	US3693603D	1970-12-14	US3693603A	1972-09-26	LEMANCZYK RUDOLF
A pulse sequence having a frequency proportional to engine speed is converted to a D.C. voltage decreasing in amplitude with pulse frequency. When this voltage has predetermined magnitude, starting fuel control switch circuit energizes a relay causing maximum fuel injection. First and second rectifier means having different frequency varying characteristics furnish, respectively, a positive and negative voltage. When combination of positive and negative voltage reaches a determined magnitude, excess speed control switching circuit energizes a relay furnishing a control signal for minimum injected fuel.
59	Fuel valve locking device	US3682267D	1970-11-03	US3682267A	1972-08-08	KAYSER ALLAN J
A three-position lock is disposed between a fuel valve and solenoid in a diesel engine and is selectively movable either to a closed position interrupting the flow of fuel from the fuel pump to the engine, an open position permitting uninterrupted flow of fuel to the engine, or to a neutral position permitting normal operation in direct response to energization or deenergization of the solenoid.
60	Switching-off device for internal combustion engine fed by a dual-body carburetor	US3678911D	1970-06-29	US3678911A	1972-07-25	SOUBIS JEAN-PIERRE
Modern high-performance combustion engines have the drawback of continuing to run at idling speed during a certain period when switched off. A known method used to avoid this phenomenon consists in shutting off the arrival of gasoline into the idling circuit of the carburetor. According to the invention when the internal combustion engine is fed by a dual-body carburetor, it is provided with only one member for stopping the feeding with fuel on only one of the two idling tubes of the carburetor and actuated simultaneously with the switching off of the engine ignition circuit.
