Abstract: ABSTRACT OF THE DISCLOSURE                A load monitoring system for indicating and controlling loads cyclically applied to force carrying members, such as the members of production presses. The system includes a high load limit circuit adapted to energize an overload detector when the loading on the member exceeds a predetermined maximum value and a low load limit circuit adapted to activate an underload detector when the loading on the member fails to reach a predetermined minimum value during a loading cycle. The low load limit circuit includes a control rectifier that is rendered conductive for a predetermined short pulse during each loading cycle in which the minimum load is exceeded and solid state logic means responsive to the failure of the rectifier to trigger during a loading cycle for activating the underload detector. The high load limit circuit includes a control rectifier that is rendered conductive only during an overload condition and solid state logic means for activating the overload detector in response to triggering of the rectifier. Once an overload or underload occurs, the circuits are adapted to be maintained in an overload or underload detecting condition until manually reset, notwithstanding an interruption of the main power supply to the system.

Abstract: ABSTRACT OF THE DISCLOSURE A disc-shaped gate-assisted turn-off thyristor having a cathode shunt is disclosed. The emitter region is a continuous narrow strip that extends in a serpentine manner to form the outline of a plurality of spaced fingers that are joined at their base near the periphery of the device, and extend inwardly a predetermined distance toward its central portion. Each of said fingers is substantially straight with arcuate strips near the central region and arcuately joined near the periphery. A metallic cathode electrode overlies inner opposing edges of the substantially parallel paired diffused cathode emitter regions forming each of the fingers to be in ohmic contact with the base region within the outline paths of each finger for electri-cally shunting the emitter with the base region therebetween.      The gate electrode which overlies the base region extends from the central portion of the device outwardly between each of the cathode fingers. The PN junction at the outside edge of each cathode finger is not beneath either the gate or cathode electrodes. A method of turning off a thyristor with a gate assist pulse and shunting such reverse current directly beneath the emitter region to the cathode electrode along paths to effectively counteract the dV/dt induced current is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a sacro-lumbar support belt which fits a broad range of patients and is also useful for pelvis traction.  This is accomplished by fabricating the belt from a urethane foam-nylon pile laminate, allowing closure at numerous points.  The belt then can be adjusted for increased support by using the adjustable plastic panels at the rear.  The entire belt with nylon pile acts as a possible site for attachment of the ends of the panels.  The foam lining of the inner surface of the belt inhibits migration of the belt especially during pelvic traction.          Again, the outer nylon pile surface of the belt allows for attachment of straps for pelvic traction at many points, as well as closure of the belt and fastening of the panels.

Abstract: ABSTRACT OF THE DISCLOSURE:             A liquid level control system is disclosed.  The system includes at least one level sensing electrode which is fixedly mounted to a vessel and projects therein.  The probe is adapted to contact a fluid within the vessel to utilize the electrical conductivity of the fluid to complete a circuit when the fluid contacts the probe.  The probe is coupled between a point of reference potential and the control electrode of a single silicon controlled rectifier (SCR).  The main electrodes of the SCR are serially coupled with the coil of a low-voltage A.C. relay and the secondary winding of a step-down transformer. Accordingly, the use of a relatively low accondary voltage avoids shock hazards; and, the sensitivity of the system is increased by the effective gain provided by the SCR.  The use of an A.C. current in the probe avoids the galvanic corrosion which other-wise follows from D.C. current operation.

Abstract: PERISTALTIC PUMP              ABSTRACT OF THE DISCLOSURE     An improved peristaltic pump is described wherein the basic configuration of movable pump rollers, a base member and pump tubing compressed by the pump rollers against the spring loaded movable base member is improved by the addi-tion of at least one actuating member capable of movement toward and away from an actuating position with respect to the base member.  When the actuating members move toward their actuating positions, they compress the pump tubing against the base member and prevent fluid flow along the pump tubing.  During such movement the actuating members also contact the base member and push it away from the pump rollers toward a non-pumping position so that movement of the pump rollers is no longer effective to cause pumping fluid along the pump tubing.  When the actuating members are retracted from their actuating positions they allow the pump tubing to open for fluid flow therealong and allow the base member to return to a pumping position.  A multiple channel pump assembly is also described.

Abstract: Abstract of the Disclosure A fluid flow-rate control device is disclosed which has a housing; an elastic stretchable membrane dividing the interior of the housing into a first and a second chamber; an inlet port of the housing leading to a fluid source and communicating with the first chamber; and an outlet port of the housing communicating with the second chamber.  The first and second chambers are in fluid communication via at least one passageway the dimensions of which remain unchanged during operation, and the membrane is fixedly held and positioned between the chambers so that when the membrane is exposed to a fluid pressure differential, it is adapted to be stretched and a portion thereof to move, solely by virtue of its elasticity, between positions closer to the outlet port to restrict the rate of flow therethrough, and positions further away from the outlet port to increase the rate of fluid flow there-through.  Thus, the flow of fluid through the outlet port is controlled at a constant rate by the membrane, despite variations in the fluid pressure at, at least, one of the ports.

Abstract: Abstract of the Disclosure A method and apparatus for decoding a high density linear bar code of the type of the Universal Product Code (UPC) symbol and derivatives thereof.  The method comprehends unambiguously decoding the encoded characters of the symbol by the use of primary ratios representative of the ratios of the sum of the widths of selected coding modules and secondary decoding ratios.  The secondary rations are selected in the even of any out-of-tolerance printing of the symbol for permitting the secondary ratios to be utilized with the primary ratios for resolving any possible ambiguities.  The method and apparatus is applicable to scanning the UPC symbol by means of a hand-held wand as well as laser beam scanning.          The apparatus contemplates the measuring of the widths of the coding modules and storing the width measurements in a memory without decoding.  Since the symbol includes a standard pattern having known module-to-module  width ratios, this information is utilized for processing the stored data to locate the measurement data in the memory, compute the printing tolerance  character and then compute the desired ratios for decoding the scanned symbol.

Abstract: ABSTRACT OF THE DISCLOSURE       A logic system requiring no tuning adjustments is provided for converting an MFM encoded information stream read from a mass storage medium to a non-return-to-zero (NRZ) information stream.  The MFM encoded information stream is routed through an input shift register to provide plural information bit cells in parallel.  Outputs of the shift register are sampled with a multiplexer to generate timing strobes for detecting an address mark, and for identifying clock bits, data bits and logic zero data appearing in the MFM encoded data field following the address mark.          Clock bits are separated from the data, and both data hits and logic zero data are applied serially to an output shift register to form a serial NRZ data stream.  Each time a data bit or logic zero data is loaded into the output shift register, a synchronization strobe is generated to transfer the NRZ data to succeeding systems.
