Abstract: HOIST                 ABSTRACT OF THE DISCLOSURE         A hoist comprises a housing carrying a fixed and slidable sheave set which are engaged by a rope.  A piston and cylinder combination are connected to the slidable sheave set for moving it and thus moving a load connected to the rope.  The piston has a threaded rod connected to the displace-able sheave set which carries a threaded nut.  The axial move-ment of the nut is restrained by a sleeve which permits rotation of the nut with axial movement of the rod.  If the axial move-ment of the rod accelerates above a selected limit, for example when the load is abruptly removed from the rope, the nut moves against a friction surface in the sleeve to brake the rotation thereof and thus brake the axial movement of the rod.

Abstract: ABSTRACT OF THE DISCLOSURE      A latex of a highly crosslinked butadiene rubber polymer comprising not less than 50% of butadiene, 1.0 to 10% of a crosslinking agent and a remainder of an ethylenically unsaturated monomer copolymerizable with butadiene, and having a particle size of 600 to 3,000 .ANG. and a degree of swelling of not greater than 7 is obtain-ed by one or more stages of emulsion polymerization.  By polymerizing 15 to 30 parts of a monomer mixture of an alkyl methacrylate, an aromatic vinyl monomer, and optionally a crosslinking agent and an unsaturated nitrile in the presence of 85 to 70 parts of the rubber polymer, a graft copolymer is obtained.  A composition comprising 2 to 40% of this graft copolymer and 98 -to 60% of a vinyl chloride resin possesses high impact resistance coupled with improved stress-whitening resistance, which proper-ties cannot be easily obtained at the same time in conventional resin compositions.

Abstract: Abstract of the Disclosure This invention concerns with fabricating devices using gas phase processes such as gas etching and chemical vapor deposition.  The gas-phase processes may be accurately monitored and adjusted via an induced fluorescence.  The gaseous phase used in the process to be monitored is probed by excitation with a suitable energy source.  The emission from the gas phase induced through this excitation is then monitored and yields an accurate measure of concentration of the active species present.  In turn the conditions of the fabrication process are adjusted based on these discerned concentrations.

Abstract: Optical Analyzing Method and System Abstract A method and system for analyzing specimens include the turning on of a high intensity lamp to produce a beam of light on one side of a container holding a specimen to be analyzed.  A signal proportional to the transmittance of the specimen is generated a predetermined length of time after the lamp is turned on, and the lamp is turned off after the generation of that signal and maintained off until the generation of a next successive signal.  Each transmittance signal is generated an equal length of time after the lamp is turned on.

Abstract: SATELLITE COMMUNICATION SYSTEM                         Abstract A beacon signal is radiated from both the communications antenna and from a separate beacon antenna, the latter having a broader radiation pattern than the communications antenna pattern and overlapping the communications antenna pattern.  The radiated signals are sensed at ground stations located about the periphery of a desired communications antenna radiation pattern coverage area on earth to provide sensor signals proportional to the ratios of the amplitudes of the two signals.  The sensor signals are compared with one another to provide an error signal indicative of any departure of the communications antenna pattern from said desired coverage area.  A control system in the satellite is responsive to this error signal for maintaining the communications antenna radiation pattern directed to the desired coverage area on earth as, for example, by controlling the attitude of the satellite.

Abstract: "Position Sensor"     ABSTRACT OF THE DISCLOSURE           A position sensor has a scale consisting of tracks of indicia in the form of bar patterns acting on a detector having a two-dimensional array of sensitive elements.  One track has indicia with a pitch slightly greater than the pitch of the sensitive elements and another track has indicia with a pitch slightly less than the pitch of the sensitive elements.          The other tracks provide a coarse determination of the position of the scale relative to the detector whilst the first two tracks provide resolution of the position to less than the pitch of the sensitive elements.  There is sufficient redundant information to enable accurate position detection even if there are optical or electrical perturbations in the detection of individual indicia.

Abstract: IMPROVED ELONGATED CHAMBERS FOR USE IN COMBINATION WITH A TRANSVERSELY EXCITED GAS LASER          ABSTRACT OF THE DISCLOSURE          The present invention is an improved laser bore and electrode structure including an elongated chamber for use in combination with a gas laser within which a laser gas is disposed.  The laser also includes first and second reflectors which reflect light energy from the laser gas discharge within the elongated chamber so that the light energy travels longitudinally the length of the elongated chamber and first and second electrodes which transversely excite the laser gas.  Each of the electrodes is formed from an electrically conductive material and they are disposed op-posing each other.  An energy generator applies a voltage of alternating polarity between the first and second electrodes at a frequency ranging from 10 Mhz to about 3 GHz to establish a laser gas discharge in the laser gas.  A coupling network matches the steady state impedance of the elongated chamber to the impedance of the energy generator and couples the first electrode to the second electrode in order to cancel the pre-ignition reactive impedance of the elongated chamber, the first impedance-matching network coupling the first and second electrodes and the second impedance-matching network to the energy generator.  The improved laser bore and electrode structure includes an elongated chamber which is in the shape of a four pointed star and which is of cross-sectional dimensions suitable for confining a laser gas discharge.  The elongated chamber is formed from a dielectric material.
