Abstract: A method and apparatus for priority sequencing a plurality of loads identifies, evaluates, assigns priority values, and couples the plurality of loads to a load managing device. Once connected the loads and load managing device are continuously powered. The load managing device includes a monitoring, detecting, and controlling section, which control the loads based on signals received from the loads and a power supply. When a predetermined condition signal is received by the load managing device the loads are allowed to run based on their assigned priority value, which is determined by the configuration of the system, i.e., in what arrangement the loads are coupled to the load managing device. A higher priority load will run by turning off lower priority loads. Once it has finished, the lower priority loads will turn on in sequence of priority, again based on the arrangement of the loads being coupled to the load managing device.

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: 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.
