Abstract: A vehicle suspension system using sensors and a computing means to vary suspension and road-handling parameters such as wheel camber, suspension spring rates, suspension damping coefficients, vehicle leveling and clearance to provide a vehicle with optimum suspension characteristics. This system is useful particularly, but not necessarily, for racing vehicles.

Abstract: A safety apparatus and system are disclosed which can be used in vessels for containing a liquifiable gas having a boiling point below the ambient temperature at atmospheric pressure. The apparatus and system provides an automatic method of cooling the vessel when the vessel is heated because of a fire in the region of the exterior of the vessel. The apparatus includes a pump to pump the liquified gas to a sprayer that sprays the liquified gas onto the vessel which is not in contact with the liquified gas. The pump is activated by movement of the vaporized gas that escapes through a pressure safety relief valve in the vessel.

Abstract: In a diesel engine, the improvement of a fuel control system for use in providing a timed supply of gaseous fuel from a high pressure source to each air input. The control system comprises a flow control valve associated with each air input, the flow control valve being adapted to open to communicate with its associated air input and to close to interrupt communication with its associated air input. A fuel supply system is provided for supplying gaseous fuel under pressure to each flow control valve. A sensor is provided for determining when diesel fuel is being injected into each cylinder and generating a control signal which indicates when fuel injection occurs and communicates the control signal to the fuel control valve associated with the cylinder which is next in the firing order to that receiving diesel fuel such that the control signal is effective to open said flow control to admit gaseous fuel to the input air of said cylinder which is next in firing order.

Abstract: In a gaseous fuel carburetion system in which air and gaseous fuel are mixed in a mixer prior to induction into an internal combustion engine, and in which the rate of flow of the induction air is controlled by throttling the intake of the air/fuel mixture, and in which gaseous fuel is supplied to the system from a pressurized source, an improved method and apparatus for regulating the supply of gaseous fuel to the air/fuel mixer is provided. The method comprises the steps of; sensing at least one operating parameter of the engine which is a function of the induction air flow rate and generating a control signal which varies in response to changes in the induction air flow rate, controlling the rate of flow of the gaseous fuel from the source to the mixer by means of said control signal whereby the rate of flow of the gaseous fuel varies in response to the sensed changes in the parameters related to the air flow rate.

Abstract: A fuel control system for use in supplying gaseous fuel from a high pressure source to an internal combustion engine which has an air/fuel intake through which air and gaseous fuel is supplied to the engine and an air/fuel intake manifold in which variations in the vacuum are indicative of engine loading conditions. The system comprises; a pressure regulator, a flow control valve, a control for measuring the speed of the engine, a modulator for modulating the fuel supply and a pressure control device communicating with said pressure regulator to increase or decrease the pressure in the gaseous fuel output in response to the receipt of a signal from the modulator. The pressure regulator receives pressurized gaseous fuel from the source and serves to maintain a constant pressure in the discharging fuel for a given engine speed regardless of flow rate and to increase or decrease the pressure in the discharging gaseous fuel in response to an increase or decrease in engine speed.
