Abstract: Abstract of the Disclosure A power output circuit is provided which is protected against latching due to voltage pulses developed by an inductive load.  The circuit comprises a transistor constructed on a monolithic integrated circuit chip including a grounded semiconductor substrate of one type conductivity, and including collector and emitter regions of opposite type conductivity located on the substrate and containing opposite type conductivity modifiers.  The collector and emitter regions are separated by a base region of one type conductivity, and the collector region is coupled to the inductive load.  A fourth region of one type conductivity, containing one type conductivity modifiers is located on the substrate in galvanic contact with the collector region.  A resistive impedance is coupled between the fourth region and a source of reference potential, and a capacitor is coupled between the fourth region and the source of reference potential.  The capacitor and the resistive impedance bias the fourth localized region above ground potential so that the current created by an inductively developed voltage pulse from the load will be conducted to the substrate by the diode junction formed by the collector of the transistor and the fourth localized region under these conditions.  Latching of the power amplifier or supply ?ircuitry is thereby prevented.

Abstract: ABSTRACT             A temperature control system including a pushbutton controlled, pneumatically operated actuator for controlling a vehicle heating and air conditioning system are disclosed.  A plurality of pushbutton operated valve members (112) enables an operator to control the system by selectively communicating a vacuum source connected to each valve member to a given position within a vented air-piston chamber (72).  A piston (74), slidably received in the chamber, is moved along the chamber by the differential pressure across the piston face until a seal member (76) located around the piston periphery blocks the orifice of the passageway (60) communicating with the vacuum source, thus substantially sealing off the chamber from the vacuum source and preventing further piston movement. The number of output positions of the actuator piston in one embodiment of the invention is equivalent to the number of pushbutton valves which communicate the vacuum source to the air chamber.  Piston movement is used to control actuation of associated heating and air conditioning system components.

Abstract: ABSTRACT           To improve the sweep efficiency of a microemulsion flooding process to recover crude oil from a subterranean formation, a mobility control polymer is added to the microemulsion to increase its viscosity. To enable the compatible incorporation of the polymer and surfactant into the microemulsion, while still utilizing an aqueous component having a salinity near that of the formation, a microemulsion oil component is used for which the surfactant's optimal salinity is substantially higher than for reservoir crude oil.

A cap is secured to the body portion and is adapted for movement axially of the body portion between container-closed and container-open positions. The cap is mounted to the body portion by means of a forma-tion extending from the upper surface of the body portion. In one embodiment, the formation defines recesses spaced 180 degrees from each other and located near the periphery of the body portion.  The cap includes a top wall having a depending skirt along the lower edge of which an annular, radially inwardly directed flange is included.  When the cap is in a closed position, the recesses and the annular flange are engaged in interlocking relationship.  In order to unlock the cap the skirt is distorted by applying force to the skirt at appropriate opposed circumferential locations until the annular flange is moved from the recesses.  Certain embodiments of the invention include an upstanding portion projecting from the midpoint of the ledge; an inner skirt depends from the top wall and snugly engages the upstanding portion.  This construction permits movement of the cap to be constrained.  In all embodiments of the invention, the cap includes a seal engageable with a sealing surface included as part of the body portion.

Abstract: ENGINE BRAKING APPARATUS                   ABSTRACT OF THE DISCLOSURE         An improved compression release engine braking apparatus is provided for internal combustion engines having two exhaust valves associated with each cylinder.          To maximize retarding power of a compression release engine braking apparatus for internal combustion engines it is necessary that a maximum  charge of air be driven into the engine cylinder and that the exhaust valve be opened at an optimum point close to the top dead center of the piston in the cylinder.  When the cylinder pressures are high, a high force is required to open the exhaust valve, such high forces subjecting the exhaust valve train parts and those constituting the compression release engine brake to elastic deformation which, in effect, increases the clearance in the exhaust valve train causing delays in the opening of the exhaust valves and reducing the time the valves are open.  To deal with this problem a slave piston of the compression release brake is relocated to register with one of the two exhaust valves and a crosshead assembly in the apparatus is modified so that actuation of the exhaust valve rocker arms will open both exhaust valves in the normal manner during the fueling mode of engine operation while the slave piston of the compression release brake will open only one of the exhaust valves during the engine braking mode of engine operation to ensure opening of the one exhaust valve at an optimum point.

Abstract: Abstract Hydrocarbons and other hazardous liquid pollutants, which are lighter than water, leaking or spilling from containers and entering the water table are intercepted by at least one deep driven, small diameter, well.  The perforated casing of the well admits water.  A water pump in the bottom of the casing establishes and maintains a predetermined water level below the water table level to create a cone of depression therearound, by gravity flow free of any centrifugal separation forces.  The pollutant fills the cone and is periodically pumped into a recovery tank by a pump/sensor assembly supported by a winch at the level of the apex of the cone.

Abstract: °     ABSTRACT OF THE DISCLOSURE             A vibratory conveyor has a continuous trough that extends over one or more linear drive units.  Each drive unit has an elongated base that extends longitudinally of the conveyor.  The base is resiliently mounted to a fixed support.  A trough support is disposed parallel to the base.  A driver is arranged to move the trough support longi-tudinally of the conveyor and relative to the base.  A plurality of leaf springs extend in an at rest position generally perpendicular to the direction of linear drive, longitudinally of the conveyor.  These leaf springs inter-connect the base and the trough support at longitudinally spaced locations.  The base and the trough support are disposed laterally of each other in a horizontal plane.  Preferably, the leaf springs are mounted for pivotal move-ment about axes extending laterally of the conveyor be-tween the base and the trough support.  Such movement adjusts the transverse angle of inclination between one side of the leaf spring and a vertical line.  This ad-justment can be made without changing the direction in which the leaf springs extend in an at rest position between the base and the trough support, and the adjust-ment provides a desired vibration angle for the trough.  The angular difference between the transverse angles of i   inclination at the sides of the various leaf springs pro-vides for rotational motion of the trough support relative to the base. This motion compensates for rotational motion of the drive unit on its fixed support due to inertia forces.
