Patent CA-1044773-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         Waveguides for transmitting micro wave signals utilize only a layer of several microns in the wall portions.          It is therefor not necessary to use massive amounts of metal in the construction.  The waveguide element according to the present invention has a body made of plastics in the form of a rectangular or circular pipe with flanges extending radially from the pipe at both end portions thereof and a thin conductive layer which is continuously provided on the inner surface of the pipe and the outer surface of the flanges.          The thin conductive layer is formed by means of, for example, plating the surface of the plastics body with a tin-cobalt alloy.  The conductive layer on the inner surface of the pipe performs the transmission of the microwave signal and the conductive layer on the outer surface of the flanges makes the electrically conductive connection together with other waveguide element or any other microwave device.

Abstract: ABSTRACT OF THE DISCLOSURE     An adsorbate is removed from an adsorbent by contact-ing the adsorbent with a supercritical fluid which is a solvent for the adsorbate.  The supercritical fluid containing the dis-solved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the super-critical fluid.  The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused.  The process and apparatus are particularly suitable for adsorbent regeneration in the treating of waste water.

Abstract: ABSTRACT OF THE DISCLOSURE         In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by taking a series of two-dimensional views of an object field and pro-jecting them in an enlarger onto lenticular print film.          Adjustable-focus and fixed-focus cameras are provided for taking the two-dimensional views, either simultaneously or sequentially, in a manner which automatically accounts for the effect of variation of the camera-to-object distance on the configuration of the enlarger-lenticular print film system, thereby allowing the parameters of the enlarger-print film system so be held constant.  The number of enlarging lenses employed may correspond to the number of two-dimensional views to be projected, by virtue of which the stereoscopic picture may be composed in a single projection step, or a single en-larging lens may be used to project the two-dimensional views in sequence.  As another feature of the invention, substantially uninterrupted and non-overlapping lineiform image bands of high image quality are formed on all areas of the lenticular film by scanning the projected images from each two-dimensional view over a predetermined distance along the photosensitive surface.

Abstract: ELECTRIC FASTENER DRIVING TOOL                  Abstract of the Disclosure An electric fastener driving tool includes a vane carried by the armature and movable in a cylinder in response to movement of the armature in drive and return strokes.          Movement of the vane in the cylinder during the return stroke displaces air through a restricted path thus preventing undesirable rebound.  The vane is unloaded during the drive stroke by a check valve controlling flow through a bypass passage extending through the vane.  The air path includes a portion surrounding the armature winding to cool the winding with air moved through the path by the vane.

Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for separating particles such as catalyst particles used in catalytic cracking of hydrocarbons, from gases in which they are suspended or en-trained.  The gas-particle mixture moves in a tube or conduit which is vented, through an outlet opening, to a disengaging chamber.  The chamber is statically pressurized by its com-munication with the conduit, but there is essentially no gas flow through the chamber, externally of the conduit.  A large proportion of the particles are inertially disengaged from the gases as the particles are projected into the chamber through the outlet opening of the conduit, while the pressure in the chamber diverts or deflects the gases angularly through a port in the sidewall of the conduit, directly into a cyclone separator, at lower pressure.           The invention provides unexpected advantages in per-mitting higher operating temperatures, higher throughputs and lower catalyst losses.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for detecting a predetermined code word contained in received signals in a transmission system which operates with four-phase or four-phase difference modulation at the transmitter and coherent demodulation at the receiver and in which successive signal increments are trans-mitted and received during successive clock periods, the code word being transmitted only as signals in two phases which are 180° apart and the received signals being divided into orthogo-nal voltage components during demodulation.  The method includes monitoring the algebraic signs of the orthogonal voltage components of the signal increment received during each clock period and providing an indication when such signs are opposite during each one of a successive plurality of clock periods one voltage component of a signal increment is then processed in a manner to invert its sign only upon occurence of such indication, i.e. when the signs are opposite, after which the processed one voltage component is algebraically summed with the other voltage component of the same signal increment.  A received signal increment is then evaluated in accordance with the algebraic sign of the voltage produced in the summing step.

Abstract: A STABILIZER UNIT FOR A PARKED VEHICLE     ABSTRACT            This invention is directed to a stabilizer unit for a parked vehicle.  Generally, on a parked vehicle there are a plu-rality of stabilizer units to lend stability to the vehicle.  The stabilizer unit is placed in a stored position when the vehicle is running or when not in use.  In the stored position, the stabilizer unit is out of the way.  When in use, the stabilizer unit is lowered so as to engage the ground and to add stability to the parked vehicle.  With four units at, approximately, the four cor-ners of the vehicle, there is greater stability for the parked vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE           A binding lace for use with a novel automatic binder developed by the present inventors is disclosed.  In the binder, the binding lace is fed continuously into a lace guide positioned around an object to be bound.          It then slides along the lace guide without buckling to form several overlapping loops.  As it is fed through the lace guide, the binding lace expands radially outwardly in the guide due to the elastic properties pro-vided by the greater rigidity and tensile stress of a core portion of the lace as compared with an outer covering portion.  This maintains a looped configuration with the loops having substantially the same diameter as that of the lace guide.  After feeding is stopped, with the binding lace main-taining the same loop diameter, the free end of the binding lace is held in the neighborhood of the overlap of the loops.  The binding lace is re-tracted from the feed end to contract the lace around the object to be bound. The lace has a coefficient of friction and elasticity in its outer portion sufficient to retain the free end substantially without slippage between the bound object and at least one loop of the lace.  In addition, the core portion of the lace effects a large tensile tightening force sufficient for binding a bundle of electric wires, while the outer portion gives a stable binding condition for a long time.

Abstract: ABSTRACT OF THE DISCLOSURE         A large, two-cycle, port-scavenging gas engine commonly used for oil field pumping operations includes a mixing section at the intake of the scavenging chamber.  Fuel gas flows through a supply line directly into this mixing section in a continuous manner controlled only by a governor valve at the gas inflow line.          In contrast, the air intake fluctuates cyclically as the engine piston reciprocates.  The present invention is a fuel regulator for such an engine which is a gas inflow control such as found in certain types of carburetors.  Thus, the maximum gas inflow is regulated by the governor valve at the inflow line, but the fuel regulator of the gas inflow control restricts the fuel gas inflow to an amount proportional to the air inflow as the air inflow fluc-tuates.
