Abstract: The essential cleaning system components for a best mode are as follows. A textile fabric covering of an article has a pile and a backing. A vacuum mat is added below the fabric covering to aid in the flow of dirt and debris from the pile of the covering. A secondary backing is also added for supporting the vacuum mat. A support platform located below the vacuum mat receives the dirt and debris through openings of the support platform. The dirt and debris is transported through channels in the support platform to a collection device. The collection device is equipped with a slider device within the collection device for maintaining adequate suction in the cleaning system. A vacuum unit pulls dirt and debris from the collection device through a vacuum line and discharges it into the discharge container. After cleaning the dirt and debris from the air it is discharged to the atmosphere.

Abstract: An effective oxygen barrier which can substantially extend the shelf life of oxygen sensitive products comprising at least outer and inner plies of a polymeric material and a substantially anaerobic space between the two or more plies.

Abstract: A lug nut removal and storage system, for removing lug nuts from lug bolts, comprising a tube. The tube has a tube exterior, a proximal end, a distal end, and a proximal distal axis. A channel extends into the distal end wherein the lug nuts are stored. A plurality of ball bearings are disposed around the channel near the distal end. The ball bearings in ball bearing bores transverse to the channel, the ball bearings moving in the ball bearing bores to narrow and widen the channel. A spring clip selectively restricts the outward movement of the ball bearings, so that the ball bearings will maintain the lug nuts in the channel, and releases the ball bearings so that the ball bearings will widen the channel sufficient to release the lug nuts from the channel. A main spring extends in the channel from the proximal end toward the distal end, the main spring biasing the lug nuts against the ball bearings.

Abstract: A cushion grip and spare battery holder is provided comprising a first piece with two receptacles. The first receptacle retains a flashlight, the second receptacle is designed to retain a spare battery within it. The invention also provides a hood which covers the end of a flashlight which houses the bulb and reflector.

Abstract: Method and apparatus are described for supplying medical gas such as oxygen to patients through flexible conduiting terminating in a cannula. Pulses of select duration of the oxygen are supplied in response to the negative pressure associated with a detected patient inhalation. Following the supply of a given pulse, the apparatus dwells for a predetermined interval, for example 0.6 seconds, whereupon a next pulse is supplied if inhalation continues. The first pulse supplied in response to any negative inhalation pressure has a quantity corresponding with a prescribed oxygen flow. Thus, subsequent pulses may supply oxygen ambulatory activities of the patient. The apparatus includes a triggering suppression feature avoiding the false pulsing effects otherwise occasioned by pneumatic transients generated by the pulsing technique. Additionally, a pulse triggering sensitivity which is manually adjustable is incorporated with the control circuit of the apparatus.

Abstract: The present invention relates to a terminal pin for electronic circuitry. The terminal pin includes an axial passageway. Various processes for electrically connecting the pin to the circuit are provided. The processes include riveting, welding and soldering. The axial passageway aids in the control of metal deformation to improve the bond between the pin and the circuitry.

Abstract: A process plate for the manufacture of molded electronic packages such as plastic pin grid array packages is provided. The process plate is a single fixture which is used to position terminal pins, align the pins for electrical interconnection and form the base of the mold during encapsulation. In one embodiment, the process plate comprises a support plate which is used for all standard terminal pin configurations and a thin cover plate which is specific for each terminal pin configuration. The process plate reduces the number of fixtures required to mold an electronic package reducing both cost and assembly error.

Abstract: A device for assessing stresses in mechanical processing of agricultural or manufactured products has a core 11 and, adjacent to the surface a layer of piezo-electric plastic material 13. The device has physical characteristics simulating those of the product. In use the device is included in a batch of products being processed and the piezo-electric signals caused by the stresses are analyzed by electronic equipment either external to or contained within the device to locate when and where damaging stresses occurred.

Abstract: A monitor and governor circuit provides speed control for an engine. The governor portion of the circuit, principally a PID controller, includes a fail safe circuit to shut the engine down in the absence of signals related to engine RPM. In addition, the governor includes a high gain feature operable during start up to keep the integrator from saturating. The speed monitor portion of the circuit prevents engine damage in the event that the speed governor should fail as, for example, due to a shorted output transistor or an open speed setting potentiometer. The end user is not required to set the speed monitor since it can be preset to a selected percent of the governor set speed.

Abstract: In a compressor assembly, the motor compressor unit is vertically supported by lower bearing head which receives the crankshaft of the compressor. The lower bearing head is vertically supported by a positioning plate which is in turn vertically supported by a spring which is received in a recess in the casing. The mounting structure comprising the head, the plate and the spring coact to provide the sole vertical support of the motor compressor unit. This single vertical support is stable because the center of gravity of the compressor is coaxial with the centerline of the spring. The position plate may be rotated to accommodate compressors having different centers of gravity.

Abstract: A multiple path input/output switching circuit particularly adapted for use with a serially accessed content addressable memory where the switching circuit embodies logical circuitry for implementing a plurality of control and data transfer functions to enhance the communication between the memory and a host system.

Abstract: A multiple path input/output switching circuit particularly adapted for use with a serially accessed content addressable memory where several simultaneous data transfers may be carried out between the memory and a host system.

Abstract: The disclosure describes an interconnection switching matrix for a data processing system which includes system resource units or processor units. Each processor unit is equipped with an interface and has the ability to control the switching matrix either by means of a stored program or on command from another processor unit. The switching matrix includes means for switching a plurality of buses between different interfaces of the units and for connecting the buses to each other. By using this technique, each unit may operate independently, predetermined units may communicate with each other to the exclusion of other units, or all units may simultaneously communicate with each other.

Abstract: A device for permitting the simultaneous transfer of a plurality of silicon wafers from one wafer carrier to another, and particularly for permitting a mass transfer between carriers having different wafer spacings. The device comprises two rectangular frames with a portion of the upper frame extending into the lower frame. Both frames are provided with a plurality of wafer slots although in the lower frame there is a greater number of slots and they are more closely spaced than in the upper frame. Each frame is adapted to interface with and be releasably secured to a carrier having a like number of wafer slots. The upper frame is slidable within the lower frame and means are provided to register its slots with different groups of the slots in the lower frame.
