Abstract: ABSTRACT         A castor comprising a socket member defined by a base portion and a cup portion extending from the base portion, the base portion being adapted to be affixed to the underside of an article, and the cup portion defining a generally dome-shaped cavity therein.  A ball is engaged in the cavity in a manner to be freely rotatable in any direction in the cavity.      The cup portion has three or more rollers rotatably mounted to the wall of the cavity and supports the ball for rotatable movement within the cavity,  the rollers being supported on bearings which in turn are supported on inwardly projecting lugs integral with the cavity walls. An annular rim defines an open end of the cavity, through which a portion of the ball outwardly projects, and a plurality of lugs are arranged circumferentially within the cavity adjacent the annular rim, the lugs projecting inwardly to engage the surface of the ball, to maintain the ball within the cavity but being resiliently yieldable to permit the ball to be mounted in or removed from the cavity by forcing the ball past the lugs.

Abstract: ABSTRACT           A pressure sensor for indicating pressure in the animal or human body, such as intracranial pressure, including a housing, a bellows contained within the housing, 3 body pressure sensing tambour for placing the bellows in communication with pressure in the body so that the pressure will cause the bellows to move as a function of the pressure, output means, such as a radioactive source and associated shielding, contained within the housing and associated with the bellows for providing an output which is a function of the movement of the bellows, and a receiver, such as a radiation detector, located external to the body to receive the output and provide data indicative of the pressure in the body.  The pressure sensor includes means associated with the bellows to enable in vivo calibration of the pressure sensor after implantation by establishing a preselected output condition during calibration.  An ambient pressure sensing tambour is associated with the bellows for compensating for ambient pressure variations.  The bellows is resilient, made of a material and shape which has essentially 100% memory of position and has a wall thickness of less than 1 mil in order to provide an output which accurately reflects the pressure being monitored.  The bellows has a spring rate which is substantially greater than the spring rate of the pressure sensing and ambient pressure compensating tambours thereby making the pressure sensor essentially insensitive to temperature variations.

Abstract: A B S T R A C T     The invention relates to a toner replenishment system for a dry toner developer unit in a photocopier.      Toner is introduced into the developer unit by means of a canister which is closed at one end and has near its other end an extractor plate mounted for rotation around the axis of the canister and for axial movement along the canister, the toner powder being disposed between the closed end and the extractor plate.  This canister can be simply loaded into a developer unit and then, during operation of the developer unit, toner demand is met at a metered rate by rotation of the extractor plate causing an extractor blade to slice toner and transfer it through the extractor plate to the axially outer side thereof for subsequent conveyance to the developer hopper.        The toner extractor member is driven by a drive rotor activated by a differential screw mechanism having at least one of the shafts of the screw members resilient to allow the drive shafts to spring apart for automatically releasing the canister on depletion of the canister contents.

Abstract: TRANSDUCER SYSTEM FOR CONTINUOUS MONITORING LIQUID LEVELS IN STORAGE TANKS AND THE LIKE     ABSTRACT OF THE DISCLOSURE The liquid level within a storage tank network is con-tinuously monitored by a transducer system of the present invention formed essentially of MSI's (Medium Scale Integrated Chips) including a differential pressure (dp) cell in circuit with a digital volt mete  (DVM)  which, in turn, is connected to a series of look-up ROM's (Read-Only Memories).  In operation and as a function of dp cell output level, DVM is continuously applying BCD signals to the ROM's, such signals being proportional to liquid level. The ROM's retain, in memory, the Gray code translations of the BCD input.  The ROM's are then periodically accessed via an analog multiplexer controlled by an oscillator/ripple counter to provide corresponding microcircuit level signals at the output of a 7-segment decoder/driver.          Thereafter, the microcircuit signals are regenerated -- at levels compatible with conventional MARK-SPACE tank gauging systems --using an isolation/driver network in circuit with the 7-segment decoder/driver.  The aforementioned system is initiated by a MARK-SPACE interrogation signal And has special utility in digitally monitoring product/source levels within source/product storage tank network associated with an oil refinery and/or a chemical complex.                            -1a-
