Abstract: A double extractor and an electrode supply station are provided for automatically replacing electrodes in opposing jaws of a resistance welding machine.   With coated sheet steels now used for car body structures, it is found that electrodes must be replaced more often.  The automatic replacement system is programmed to replace electrodes when the welding machine  is  idle  such as between the movement of car bodies or other structures moving on a conveyor.   A double extractor has a first position  for  extracting  top  electrodes  and  a  second position for extracting bottom electrodes.  Both positions have a plurality of gripping fingers operated by a cam, which simultaneously twist and pull-off the electrodes from the jaw.   After the  jaw has been removed,  the gripping fingers release the old electrode.

Title: Circuitry for decoding huffman codes
Inventor: KEITH MICHAEL
IPC: H03M7/40
Filed: 1992-12-14
Abstract: A variable-length decoder system decodes a variable-length code having different code prefixes in an input bit stream. A code prefix is located in the bit stream and used to determine a number of bits to be selected from the input bit stream according to an access of a code book. Additionally, a pointer, directing access to a different code book, may also be indicated by the access of the first code book according to the located code prefix. A  determination is made in this decoder system whether to perform the operation of determining a number of bits to be selected from the input stream or accessing a second code prefix table. If the code value is valid, the number of bits is selected and appended to the code prefix to form a code word which is later decoded by the system of the present invention. If another table is indicated a further code prefix is located in the input stream and the further lookup table is accessed in accordance with the further code prefix.

Title: Process for heating an asphalt surface and apparatus therefor
Inventor: WILEY PATRICK C
IPC: E01C23/14
Filed: 1994-09-02
Abstract: A process for heating an asphalt surface and an apparatus therefor.      The process comprises the steps of: igniting in a burner a combustible mixture comprised of a fuel and oxygen to produce a hot gas; and feeding the hot gas to an enclosure having a radiative face disposed above the asphalt surface. The asphalt surface heating apparatus comprises a hot gas producing burner and an enclosure comprising an inlet for receiving hot gas from the burner and a radiative face having a plurality of apertures.  The apertures in the radiative face are of a dimension such that the hot gas: (i) heats the radiative face to provide radiation heat transfer to the asphalt surface; and (ii) passes through the apertures to provide convection heat transfer to the asphalt surface. The radiation heat transfer is from about 20% to about 80% of a total heat transfer, the remainder being convection heat transfer. This arrangement allows for improved efficiency of heating and asphalt surface.

Patent CA-2132245-A1 (CA)
Inventor: SCHNEIDER ARTHUR J
IPC: F41G7/00
Filed: 1994-09-16
Abstract: A method that provides precise target location measurement using a synthetic aperture radar (SAR) system jointly with a global positioning inertial navigation system (GPS/INS) located on a moving aircraft. The SAR system provides a precise measurement of the round trip elapsed radar wave propagation time from the aircraft location to a selected pixel in a ground map that includes a portion of the target. The velocity of radar wave propagation is measured at the same time that the range time lapse to the designated SAR map pixel is measured. When combined with position and velocity information derived from the GPS/INS inertial navigation system, the radar wave propagation time is used to calculate the position of the target pixel in GPS/INS coordinates, thereby improving measurement accuracy. The method comprises flyingan aircraft containing GPS/INS and SAR systems along a predetermined flight path. The relative position and velocity of the aircraft along the flight path is accurately measured using the the global positioning system. A first SAR map is generated. A target pixel in the first SAR map that corresponds to the target is then designated. A minimum of two additional SAR maps are generated and the target pixel in each of the additional SAR maps is designated. The position of the target pixel relative to GPS/INS coordinates and the velocity of radar wave propagation to the target using aircraft position data derived from the global positioning system are then simultaneously measured. Finally, a more accurate position for the target pixel is calculated using the computed value for the radar wave propagation velocity.

Title: Method and apparatus for stimulating a laser diode in a fiber optic transmitter
Inventor: LEVINSON FRANK H
IPC: H01S5/062
Filed: 1993-06-01
Abstract: A fiber optic transmitter circuit (10) includes a DC bias circuit (12) that produces a DC voltage, an amplifier circuit (U1) having data signal inputs and that produces a data signal and wherein the data signal and the DC voltage are supplied to a laser diode (U2) to stimulate the diode (U2) to produce light of a corresponding nature. The amplifier (U1) is selected so that the inher-ent noise level or noise figure characteristics of the amplifier are such as to provide stimulation of a single mode laser diode in the frequency band wherein the resonant frequency of the laser diode is typically found. The resulting impact of the noise on the laser diode is to transform the single mode laser diode into a multi-mode laser diode thereby reducing the impact of modal noise on the fiber optic data transmission system that incorporates the disclosed fiber optic transmitter device.

Abstract: A clip-on pointing device (10) attaches to the front of a portable computer. The pointing device connects directly with cir-cuitry internal to the computer by means of a connection port formed on the front of the computer. In one embodiment, the poin-ting device attaches to the computer by means of a mounting clip (140) which comprises a unitary sheet of metal. The mounting clip (140) includes a top arm (142) and a bottom arm (202) which provide a spring tension when flexed. The top arm (142) in-cludes a gripping rail (144) which engages with a ridge on the frame of the computer. The bottom arm (202) includes a plurality of gripping tabs (210) which engage with slots (225) formed on the underside of the computer. The mounting clip (140) slides onto the front of the computer and snaps into place by virtue of the spring tension produced within the top and bottom arms of the mounting clip. Due to the thinness of the mounting clip (140), and the direct connection between the pointing device and the in-ternal circuitry of the computer, the computer may be closed and carried without detaching the pointing device from the front of the computer.
