  • Patent number: 4775237
    Abstract: An improved electro-optical detection system is disclosed capable of use in a fluorescent polarization instrument. In a single or dual channel system, an integrated photodetector/amplifier is combined with a linear charge-balancing voltage-to-frequency converter to produce a digital frequency indicative of the intensity of polarized fluorescence emmited by a chemically treated body fluid sample, such as blood, upon light excitation thereof. A chopper-stabilized amplifier is further connected to the input of the voltage-to-frequency converter for automatically correcting input offset currents and temperature drift. The digital frequency is counted and the data corresponding thereto is transferred via bus connection to a microcomputer for evaluation and display.

  • Patent number: 4723760
    Abstract: An adjustable fence assembly is disclosed constructed in sections having at least a pair of vertically oriented end posts for establishing the location of a respective section in the ground. Intermediate the end posts, a plurality of tubular pickets are mounted in a substantially vertical direction upon a series of tubular rails horizontally oriented and pivotally mounted between the end posts. Each rail is fabricated having a plurality of paired openings spaced apart along the length of the rail and corresponding in number to that of the pickets. Vertically aligned on opposite sides of each rail, both of the paired openings are shaped to accept and hold a respective one of the pickets with one of the openings being additionally formed to provide an apertured flap interior to the rail. The aperture in each flap is adapted to accept a rod extended longitudinally through each rail to interlock the rail with a crossing picket.

  • Patent number: 4677761
    Abstract: A sieve drum is disclosed that is particularly useful in textile processing equipment, such as a suction drum dryer, for heat-treating of continuous web material. The sieve drum is constructed having a single layer of a close mesh screen cylindrically formed between a pair of end heads to provide support for and transmit torque to web material being processed. The close mesh screen is composed of a plurality of longitudinal and transverse wire lengths of relatively heavy gauge than are sinusoidally woven into a lattice having a multitude of small interstitial openings each with rounded edges to provide smooth, unabrasive support to the web material. The multitude of small openings the aggregate area of which comprises less than 50% of the screen surface provides an even distribution of heated air over the surface of the drum and exposes a high percentage of the supported web to the air for a fast, energy efficient heat-treating process.

  • Patent number: 4602210
    Abstract: A testable integrated circuit contains additional circuitry which defines--when operable in a test mode--a plurality of scan paths in each of which are connected in series a plurality of bistable elements (specifically, special scan path flip-flops) isolated from the integrated circuit combinational circuits. The input and output ends of these scan paths are connected by multi-level demultiplexer and multiplexer arrangements with the input and output pins, respectively, of the integrated circuit. The last level demultiplexer and the last level multiplexer include first groups of connections with the input and output ends of the scan paths, respectively, and second groups of connections with the input and output ends of the mission logic. The demultiplexers, the multiplexers and the scan path flip-flops are operable between mission and test modes upon the application of a mode control signal thereto.

  • Patent number: 4597822
    Abstract: A method for manufacturing a silicon wafer includes growing a layer of low-resistivity crystalline silicon upon a precision-ground slice of single-crystal, high-resistivity silicon. The slice of single-crystal silicon has a thickness sufficient to withstand handling during the initial part of the processing. The crystalline silicon is built up to a thickness which is sufficient to withstand handling and processing of the finished wafer. The layer of single-crystal silicon is thereupon precision ground to reduce its final thickness to a value required for the devices to be formed thereon. The crystalline layer performs gettering to remove impurities from the single-crystal silicon during normal heating attendant to the formation of the solid-state devices thereon. The present invention further includes a silicon wafer made by the process of the invention.

  • Patent number: 4570783
    Abstract: A method is disclosed for automatic operation of an accumulator conveyor in conjunction with a main conveyor which transports odd shaped articles between two operational stations of an automated system. The method comprises the passing of articles into the entry end of the accumulator conveyor at a first speed when downstream equipment malfunctions causing articles to back-up along the main conveyor. When the back-up is dissipated, the articles stored in the accumulator conveyor are passed from the exit end of the accumulator conveyor on a first-in, first-out basis to the main conveyor at a second, faster speed while additional articles from the upstream equipment continue to enter the accumulator conveyor, also at the second speed. When all of the previously stored articles have passed back to the main conveyor, the main conveyor is operated normally with no articles passing into or out of the accumulator conveyor.

  • Patent number: 4535770
    Abstract: A cardiovascular tourniquet and surgical method of applying the same is disclosed for use in support of a cannula operatively inserted into a blood vessel with a purse string suture. Ends of the suture are drawn to close the blood vessel around the cannula and then passed through a tubular member having integrally formed rib-like sections spaced apart along its length. The tubular member is firmly secured alongside the cannula by at least a pair of spring clips fastened about the cannula and adapted to grasp the tubular member between its rib-like sections. An integral cap is further provided at one end of the tubular member for releasably clamping the suture ends drawn therethrough thereby preventing the suture from loosening during subsequent procedures and maintaining proper disposition of the cannula.

  • Patent number: 4519245
    Abstract: A method and apparatus for the non-destructive testing of materials, particularly composite structures and other such laminated materials, which comprises repeatedly impacting the material being tested with a precisely regulated force having a pre-determined magnitude. The response generated by the material is detected by a sensor and a proportional electrical signal is generated. The electrical signal is compared with a stored electrical signal previously generated in response to impacting a defect-free reference material with the same precisely regulated pre-determined force. A difference in frequency and amplitude between the two compared electrical signals is indicative of a defect in the material being tested.

  • Patent number: 4512346
    Abstract: An improved sternal closure device and method for using the device is disclosed wherein a pair of thin rods of appropriate length are positioned longitudinally along respective opposite sides of a severed sternum on the posterior surface thereof. Individual wires secured at one end thereof to corresponding points along each rod are passed through matching holes on either side of the severed sternum to extend beyond its anterior surface. Opposing pairs of wires transversely oriented are tensioned to draw the sternum together and knotted thereby holding the sternum closed with forces applied by the wires and distributed along the length of the sternum via the rods. Alternatively, the wires may have looped inner ends that engage the rods on the posterior surface of the sternum for distribution of the closing forces.

  • Patent number: 4416153
    Abstract: A computer-aided monitoring system and associated technique is disclosed for automatically controlling the liquid level of a heated tank subjected to changing temperatures. A first voltage signal from a thermistor sensor mounted within the tank at a predetermined level is digitally converted to multi-bit data indicative of fluid level. A second voltage signal produced by a separate thermistor sensor attached to the tank is digitally encoded as an indication of tank temperature and used to address a look-up table of voltage threshold values stored in a read-only memory. Empirically determined to vary linearly as a function of tank temperature, the voltage threshold values addressed are compared with the digital level data to determine if the liquid flow to the tank should be discontinued via a central processing unit.
