Abstract: An engine induction system for reducing engine pumping losses provides for a minimum of two intake valves per cylinder, a primary and secondary, with valve port activation means associated with the secondary valves to control air flow to them so that at light loads only air flows through the primary intake valves, the secondary valves providing air flow at heavier loads, the primary intake valve openings being controlled so that no more than one primary valve is open at any one time; i.e., there is no overlap in openings between primary intake valves, which produces pumping losses at light loads when intake manifold vacuum is high.

Abstract: A pneumatic transport and distribution system for passing gas-entrained particles to a distributor which then distributes the particles through a plurality of distributor outlets. At least a portion of inlet conduit extending vertically to the distributor is of square or other non-circular inner cross-section for prevention of "spiralling" of the particles as they emanate from the distributor inlet into the distributor to thereby improve the flow distribution of the particles from the distributor outlets.

A compression plate with a central opening having a diameter slightly larger than the diameter of the upper portion of the mandrel stem fits over the mandrel stem, and an annular sealing ring is positioned around the periphery of the mandrel plate above the annular shoulder and in contact with the compression plate when the compression plate is positioned over the mandrel stem.

Abstract: An automotive type internal combustion engine has an air throttle body for providing air to the engine for combination with fuel injected to define a fuel air charge; the air throttle body having primary and secondary air passages controlled by throttling valves, the primary passage being a drive-by-wire electrical system in which the throttle valve is moved electrically in response to movement of the vehicle accelerator pedal, the secondary passage being controlled by a throttle valve that has a direct mechanical connection to the vehicle accelerator pedal to be operative at wide open or near wide open throttle positions of the accelerator pedal to not only supply additional air for wide open throttle operation, but also to supply sufficient air to sustain engine operation in the event of inoperativeness of the electrical system or the actuator/motor affecting movement of the primary throttle valve.

Abstract: This invention comprehends an improved method for uniformly loosening and removing the thin layer of mold flash which deposits on the surface of the metal lead frames during encapsulation of the silicon integrated circuit chips bonded to that metal lead frame surface. The disclosed method does not adversely effect the underlying metal material or the encapsulating plastic material enveloping the silicon integrated circuit chip. The disclosed method is electrolytic and employs (1) the chemical dissolving action of the stripping solution and (2) the percolating effect of the hydrogen gas generated during electrolysis of the water, to loosen the unwanted organic mold flash from the metal lead frame surface.

Abstract: A retractable safety latch is disclosed and includes a base mounting member having perpendicular base walls, a draw bar guide attached to the mounting base member by a hinge, a draw bar having an arcuate hook on one end and an eccentrically positioned oblong hole on the other end slidably mounted on the draw bar guide, a rotatable shaft mounted on the draw bar guide and having an eccentrically mounted pin extending through the oblong hole for driving and retaining the draw bar in the draw bar guide, and a handle having a safety catch pivotably mounted on the rotatable shaft. Between the handle and the rotatable shaft is a spring for the purpose of biasing the handle in one direction with respect to the rotatable shaft so that when the latch is closed, the handle is in contact with the perpendicular base walls and the safety catch catches on one of the perpendicular base walls to prevent the rotatable shaft on which the handle is mounted from rotating and opening the latch.

Abstract: In a compressor which includes an upper and lower head portions and an interposed diaphragm, provisions are made for increasing the service life of the diaphragm by reducing the incidence failure of the diaphragm due to fretting products and airborne contaminants, which collect at the outer edge of the diaphragm which results in stress concentrations at the outer edge of the diaphragm, and specifically by providing a plurality of concentric grooves in the upper head of the compressor to remove the fretting products and gas borne contaminants from build up at the outer edge of the diaphragm.

Abstract: Charged beam accessible data storage methods and devices involve a storage medium having an array of protrusions formed on a thermally insulative, substantially charged beam transparent base. The protrusions, made of high contrast material, can be selectively melted by a charged beam, such as an electron beam, in order to decrease the protrusions' aspect ratio and to increase their energy absorptive action when scanned by a charged beam. Since the melted protrusions do not wet on the base, the protrusions quickly assume a spherical bead shape when melted due to favorable surface tension forces. The bi-level charged beam absorption characteristics of the melted and unmelted protrusions provide the two "on" or "off" stored data states.

Abstract: A display assembly for displaying and storing articles such as greeting cards. The assembly involves a support structure for supporting one or more individual display units with each of the display units having a storage compartment and a display compartment. Means are provided on the display units whereby one display unit can be joined to another display unit.

Abstract: A high security lock of the type having a base, a bolt which moves on the base and engages a strike, and a dead lock tripper which interacts with the strike to automatically lock the bolt is improved by including a lock prevent member in association with the bolt. The lock prevent member inhibits the bolt from moving from an unlocked to a locked position in spite of the dead lock tripper interacting with the strike. A secondary key can be used to inactivate the lock prevent member such that the lock returns to its normal mode of operation with the interaction of the dead lock tripper and the strike automatically locking the lock.

Abstract: A material metering device having a feed wheel adjustably positioned above the housing discharge orifice. The feed wheel is disposed to rotate on a shaft journalled in an eccentric bearing.

Abstract: A material metering device having a discrete flow rate adjustment and indicator mechanism. The indicator includes an actuator knob which is rotated to adjust the flow rate of material from the meter. The actuator knob is also operably connected to a follower wheel which is rotated by movement of the actuator knob. Indicia on both the actuator knob and follower wheel are simultaneously registerable with a reference point, such as a viewing window, and the reading of the indicia at the reference point indicates the flow rate of material from the meter.

Abstract: A switching device for effecting electrical continuity in an alarm circuit in response to the wave motion created by the ingress of a relatively large object into a pool of water or the like. The device includes an elongated member having an open interior chamber adjacent to its upper end, said chamber communicating with the exterior of said device and containing a float which is longitudinally movable within the chamber to effect electrical continuity between a pair of spaced electrical terminals in the member. The device is floatable in a pool of water or the like with at least the top portion of said member and said chamber above the surface of the water and with the bottom portion of said member extending well beneath the surface of the water. As the member bobs or oscillates in the water, the float moves upwardly within the chamber to effect continuity.
