The heat pump system of the present invention is adapted to continuously withdraw heat from a heat source and continuously deliver heat at a required rate to a heat sink such that the ratio of heat delivered to heat withdrawn may be controlled by a cooling means, said heat pump system comprising a compressor adapted to compress at least a portion of refrigerant vapor from an evaporator thereof wherein a refrigerant withdraws heat from said heat source, a condenser in which refrigerant vapor so compressed is condensed and delivers heat at the required rate, cooling means for balancing the rates of heat delivery and heat withdrawal, and an expansion valve for expanding liquid refrigerant from said condenser into said evaporator.

Abstract: A hydride fuel system is disclosed for use with a motor vehicle or other apparatus having a combustion unit and a mixing device for mixing hydrogen gas with air for introduction into the combustion unit. The system includes a hydride storage tank having a housing and a plurality of containers disposed in the housing for holding hydride material. The containers are spaced apart to enable the flow thereabout of fluid introduced into the housing of the hydride storage tank. Either exhaust gases or combustion unit cooling fluid is delivered into the hydride storage tank housing to heat the hydride material in the containers and cause the material to release hydrogen gas which is then conveyed to the mixing device. The pressure of the hydrogen gas in the containers is monitored and the amount of exhaust gases or cooling fluid delivered to the hydride storage tank is controlled accordingly.

Abstract: An improved piston assembly for high-power internal combustion engines such as supercharged diesel engines. The piston includes separate head and skirt portions. An elongated tubular-shaped bearing member having an internal bearing surface and an external journal surface is formed across the bottom of the piston head. A connecting rod passes through an opening in the lower center of the bearing member and is attached to a wrist pin which rotates against the internal bearing surface of the tubular-shaped bearing member to permit rotational movement between the connecting rod and the piston head. The wrist pin is supported by the bearing surface along its entire length to prevent any flexing of the wrist pin when high compressive forces are applied to the piston head. The skirt is connected to the piston head by thrust bearings which engage the external journal surface of the bearing member substantially along its entire length to permit rotational movement between the piston head and the piston skirt.

Abstract: A piston for a heat engine has a chamber adjacent the piston head, for receiving cooling oil for cooling parts of the piston that in operation are subjected to elevated thermal stress. An oil inlet and an oil outlet provide for a suitable flow of oil into and out of the chamber, to ensure controlled cooling of the piston in particular of the piston head surface and the piston ring area. The chamber can be of annular shape so that the central part of the head surface remains uncooled.The invention is particularly suitable for a composite-structure piston.

Crosshead reciprocates on the crosshead guides positioned between and parallel to the cylinders. Connecting member has outer ends of piston connecting arms slidably and rotatably connected to pistons to accommodate changes in angle of connecting member, with outer end of crank connecting arm journalled on crankpin. Clearance openings extend between inner side walls of cylinder and crankcase to accept piston connecting arms, outer ends of openings serving as inlet ports. Exhaust ports are provided on generally opposite side of cylinder to inlet ports to permit efficient scavenging of spent charge.

Abstract: The pressure and temperature and in some cases the flow rate of fluids such as polymers are controlled by reducing the cross-sectional area of the conduit carrying the fluid to provide a flow channel communicating with the inner surface of the conduit whose cross-sectional area is less than that of the conduit. A valve housing is provided containing a chamber which communicates with the flow channel. The pressure and temperature and in some cases the flow rate of the fluid is controlled by adjusting the position of a valve member slideably disposed in the chamber. As the valve member slides within the chamber, it enlarges or reduces the cross-sectional area of the flow channel to change the flow resistance of the channel, thereby changing the pressure and temperature upstream of the channel and in some cases the flow rate through the channel.

Abstract: An intake system for an internal combustion engine has been developed to include a translationally movable throttle to cause cross-sectional passage of the intake manifold of the engine cylinders to vary. This throttle utilizes a substantially rigid plate which is pierced with orifices adapted to be connected with each of the intakes corresponding to the various engine cylinders. A movable blade is provided with apertures corresponding in number and spacing to the orifices which contacts with a control and guide means so that the blade is allowed to move parallel to the plate from a running position in which the apertures of the blade are substantially opposite the orifices of the plate to an idle position in which at least the majority of the orifices of the plate are obturated by the blades.

Abstract: An opposed piston engine includes pistons mounted at opposite ends of a piston rod which is pivotally coupled to one end of a rocker arm coupling the piston rod to a connecting rod in turn coupled to an eccentric drive mechanism. The rocker arm is pivotally coupled to the engine block by pivot means permitting necessary lineal movement of the rocker arm during operation. Counterbalance arms are pivotally coupled to the engine block at one end and include weighted portions positioned to provide counterbalancing for the opposed pistons. Pivot means couple the rocker arm and the counterbalance arms for providing the desired relative motion between these elements. A hollow drive shaft is coupled to the eccentric drive mechanism and a transmission shaft extends through the drive shaft to permit positioning of a clutch at one end of the engine and the transmission at the other.

Abstract: An engine includes a block having at least one cylinder in which a piston reciprocates. The piston is connected through a piston connecting rod to a lever arm, and the lever arm is in turn connected to the eccentric crank pin of a crankshaft through a crank connecting rod. The lever arm is positioned and moved not only by the piston and crankshaft, but also by a positioning cam which bears against one end of the arm. The arrangement is such that throughout the entire power stroke the force transmitted to the crankshaft is applied through a relatively large moment arm, thus providing greater torque for the engine. The arrangement results in a relatively large angle between the crank connecting rod and the crank arm and permits greater eccentricity on the crank arm.

Abstract: A caging mechanism for a gyro in which a flat split ring lying in a plane perpendicular to the gyro rotor spin axis is deformable so that its inside diameter is enabled to capture the gyro rotor. A gas activated piston separates tabs formed on the split ring causing it to cage or uncage the rotor.

Abstract: A vent valve allows a combustion chamber arranged to burn a swirling lean mixture to communicate with either an intake manifold or exhaust manifold through a vent port by-passing the intake or exhaust valve, for a short period just before ignition to discharge a fraction of the mixture from the combustion chamber. The discharge weakens the turburent flow of the mixture and results in a decreased combustion temperature, which is advantageous for suppression of NOx formation and prevention of combustion noise generation.
