  • Patent number: 5278953
    Abstract: A video image of the article to be produced is displayed on a computer. A first geometric shape is developed to enclose fully the video image of the article. The first geometric shape provides a video image of a workpiece of machinable stock and the approximate unscaled dimensions of the workpiece. A selection is made from a library of known machine tool tables to select the exact type of machine tool table to be used to produce the article. The video image of the table is positioned visually underneath each of the video image of the article and first geometric shape. The video representation of the machine tool table includes a frame of reference origin which corresponds to the actual machine tool table zero reference.

  • Patent number: 5220293
    Abstract: A high reliability phase-locked loop (PLL) is disclosed having a hyperactivity detection and correction circuit (HDC) to oversee the oscillator and the phase and frequency detector (PFD), and having a PFD reset gate that performs the required logic function to reset the PFD while not being vulnerable to an internal PFD race condition that plagues prior art phase-locked loop circuits. The HDC senses the oscillator control and signals an oscillator reset should the oscillator control rise to an abnormally high level above a predetermined limit while the PFD is not detecting the feedback signal. The oscillator reset signal then slowly propagates through an asymmetrical delay line and resets the oscillator control to a predetermined reset state. While the oscillator control is being reset, the HDC continues to monitor the oscillator control, and de-asserts the oscillator reset when the oscillator control drops to the predetermined reset state.

  • Patent number: 5178007
    Abstract: An apparatus (20) for testing a specimen sample of fibers includes a frame (22), rotatable drums (60) situated at a first station upon the frame for holding a quantity (86) of fibers, a brush (152) situated at a second station along the frame for brushing the fiber specimen and testing equipment (28) situated at a third station upon the frame for performing a series upon the fiber specimen. A comb (34 or 35) is utilized for gathering the fiber specimen from the quantity of fibers held by the drums, and carriages (122 and 136) are movably mounted upon the frame for transporting the comb between the first, second and third stations of the apparatus. When positioned at the first station, the comb gathers a fiber specimen, and the specimen is carded. When the comb is positioned at the second station, the gathered specimen is brushed by the brush, and when the comb is thereafter moved to the third station, the brushed specimen is tested by the testing equipment.

  • Patent number: 5174222
    Abstract: A device is disclosed for in-water cleaning of a ship's hull. The device includes a body having inboard and outboard faces joined by a peripheral side, the faces having coaxial central apertures which are joined to form a central opening through the body, in which is mounted a hydraulic motor-driven propeller. The propeller maintains the device in contact with the hull during cleaning. There are detachable wheel modules recessed into the body to propel the device along the hull and a hydraulic motor-driven steering wheel to steer the device. Hydraulically driven cleaners are mounted on the inboard face to clean the hull. There is also a light recessed into the peripheral side to provide illumination to the hull. The device may also include an adjustable buoyancy chamber mounted on the body to provide sufficient buoyancy to the device to enable the device to effectively clean the hull at the waterline.

  • Patent number: 5149991
    Abstract: An output buffer circuit incorporates a ground bounce blocking circuit which blocks transfer of ground bounce pulses from the output ground lead (GND,PGND) to the output (V.sub.OUT) for protecting quiet outputs tied to a common ground bus. A diode element (SD1,D1,ND1, NSC) is coupled in the sinking current path in series with the primary pulldown transistor element (N1,N1P) between the buffer circuit output (V.sub.OUT) and the ground rail (GND,PGND). The diode element is oriented for passing sinking current to the low potential ground rail and for blocking transfer of ground bounce pulses originating in the ground rail (GND,PGND) to the output. The ground rail may be bifurcated to provide a relatively noisy output ground lead (PGND) and a relatively quiet ground lead (QGND). The primary pulldown transistor element (N1P) is coupled to the relatively noisy output ground lead (PGND).

  • Patent number: 5121967
    Abstract: A rocker recliner having carrier scissor links mounting the seat and backrest assembly to the rocker cams through a pair of front and rear mounting links mounted on the cam. Rocking motion is prevented when the chair is in T.V. and advanced reclining positions by a linkage pivoted to the base, rocking cam and the rear mounting link. This rock-blocking linkage idles when the chair is rocking but becomes unified to prevent rocking of the cam when the chair moves into T.V. position.

  • Patent number: 5087841
    Abstract: TTL to CMOS level translating buffer circuits incorporate multiple stages with feedback and forward couplings between stages that eliminate static current I.sub.cct when TTL high potential level data signal is applied at the buffer circuit input. The feedback and feed forward couplings maintain and enhance signal propagation speed in the buffer circuits at the same time. TTL to CMOS translating latch circuits and flip-flop circuits similarly incorporate feedback and feed forward circuit couplings to save and retain data signals during latch mode, static mode, and tristate mode operation while at the same time substantially eliminating static high current I.sub.cct. The clock circuit portions for the latch and flip-flop circuits also are arranged in clock circuit configurations that are free of static current I.sub.cct.

  • Patent number: 5087094
    Abstract: A recliner has a layer of upholstery fixed to the seat and extending continuously and fixed to a footrest frame which is moveable to a retracted position below the front end of the seat with the upholstery extending about and vertically below the front end of the seat. The footrest frame may include one or two ottoman boards mounted to a footrest linkage which will cause an ottoman board to pull the upholstery layer taut. In one embodiment, a pair of locking links are mounted to the footrest linkage and connected to each other for releaseably holding the footrest linkage in retracted position. In another embodiment where two ottoman boards are used, two pairs of conventional four bar linkages may be incorporated in the footrest linkage without sacrificing the desired contour of the upholstery.

  • Patent number: 5061864
    Abstract: Intermediate path splitting circuit arrangements are coupled between the input node and output stage of an IC defining a plurality of different signal propagation paths. A relatively higher speed output pullup turn on signal progagation path is coupled between the input node and the output pullup transistor element for turning on the output pullup transistor element at relatively higher speed in response to a first input data signal. A relatively slower speed output pulldown turn off signal propagation path turns off the output pulldown transistor element at a relatively slower speed in response to the first data input signal. Similar circuit arrangements are provided for relatively high speed turn on of the pulldown transistor element and relatively low speed turn off of the pullup transistor element. Control of turn on and turn off of the respective output pullup and pulldown transistor elements is from separate output driver nodes for higher speed operation.
