Abstract: HYDROGEN-HYDRIDE ABSORPTION SYSTEMS AND METHOD FOR          REFRIGERATION AND HEAT PUMP CYCLES                  Abstract of the Disclosure A hydrogen-hydride absorption system comprising two reactor systems for chemically forming two hydride components, means for supplying heat to, and removing heat from, the com-ponent systems, means for partial thermal energy recovery from reactors in each of the systems, and means for conveying hydro-gen between component reactor systems.    A method for deriving refrigeration includes the steps of dehydriding the hydride of a first component reactor using a relatively low temperature thermal source and conveying the hydrogen to a second component reactor to be absorbed, and rejecting heat, decreasing the pressure of both component reactors along with partial heat recovery, supplying heat as a refrigeration load to dehydride the second component reactor and conveying the hydrogen to the first component reactor, and pressurizing both reactors through partial heat recovery and further heating.    A method for deriving heat pump effects includes the steps of absorption of hydrogen conveyed from a second com-ponent reactor to a first component reactor with the subse-quent release of heat at a high temperature, depressurizing both component reactors, dehydriding a first component reactor and conveying the hydrogen to a second component reactor with rejection of heat at a low temperature, and pressurizing the component reactors.

Abstract: ROTARY ROCK BIT WITH THE BEARING   PIN FUSED TO THE ROCK BIT ARM                     Abstract of the Disclosure A rotary rock bit is constructed from at least one rock bit arm and a separate bearing pin.  The rock bit arm includes a curved shirttail surface, a plane cutter receiving surface, and a mounting passage extending through said rock bit arm from said cutter receiving surface to said shirttail surface.  The bearing pin includes a bearing section and a mounting section.  The mounting section is positioned in the mounting passage of the rock bit arm thereby forming a seam between the mounting section of the bearing pin and the mounting passage in the rock bit arm.  The mounting section of the bearing pin is fused to the rock bit arm using a beam of energy.  The beam of energy is directed from an energy source located on the plane cutter receiving surface side of the rock bit arm.  The plane cutter receiving surface is maintained substantially perpendicular to the beam of energy and the beam source is maintained substantially at a fixed distance from the cutter receiving surface during the fusing operation.     -1a-

Abstract: DOUBLE PARALLELOGRAM JACK Abstract Of The Disclosure A load-bearing plate is mounted by a plurality of pivotal links above a base plate, and solely for vertical move-ment toward and away from the base plate. An intermediate frame including two, spaced, parallel side bars is supported by the links between the two plates for swinging movement on the base plate about a pair of spaced, parallel axes. Driving means, such as a hydraulic screw jack is mounted between the two side bars for swinging movement therewith, and has a reciprocable piston rod attached to one of two, parallel pins mounted at opposite ends in slots in the side bars to reciprocate longi-tudinally of the bars during the raising and lowering of the load-bearing plate. The reciprocable movement of the two pins oscillates the links which in turn cause the load-bearing plate to reciprocate only vertically relative to the base plate.

Abstract: THERMAL HYDROCRACKING OF TOPPED HEAVY OILS     Abstract of the Disclosure An improved process is described for the thermal hydrocracking of heavy hydrocarbon oil, such as oils ex-tracted from tar sands.  The charge oil in the presence of an excess of hydrogen is passed upwardly through a vertical hydrocracking zone and the effluent emerging from the top of the zone is separated into a gaseous stream and a liquid stream containing heavy hydrocarbons.  According to the novel feature, the heavy hydrocarbon charge oil is one which has been topped in a distillation column to an equivalent at-mospheric boiling temperature of at least 350°C.  It has been found that the topping of the charge oil results in lower hydrogen consumption per barrel of pitch converted.          Surprisingly, operability of the plant is improved with heavier feed and significantly lower coke formation being experienced.

Abstract: APPARATUS AND METHOD FOR DETECTING METABOLIC ACTIVITY          Abstract of the Disclosure An apparatus and method for detecting metabolic activity in a medium which includes an electrical circuit suitable for passing electrical current through a medium which contains a suspected metabolic agent.  The circuit includes means for generating a reference voltage.  When metabolic activity occurs in the medium the voltage drop thereacross changes.  To balance the changing voltage developed across the medium with the generated reference voltage, an adjustment of current has to be performed.          By monitoring such adjustments, made electrically and automatically, there is a correlation made between those adjustments and the metabolic activity in the medium.          Use of this apparatus and method allows large quantities of sample media to be tested for detection of metabolic activity rapidly, accurately and reliably.

Abstract: ABSTRACT OF THE DISCLOSURE           A spacer tube for a hermetically sealed double glazed window in accordance with one aspect of the invention is formed from an elongated strip of metal bent into a hollow elongated tubular shape.  The spacer tube has opposing side wall portions and a base extending between and connecting the side wall portions.  The spacer tube also includes a further wall spaced from the base, such further wall defining a region wherein the longitudinal edges of the strip extend toward each other.  That surface of the base which faces into the interior of the spacer tube has a plurality of closely spaced ridges therein, the ridges being spaced apart in the lengthwise direction of the spacer tube and the individual ridges extending generally transversely of the longitudinal axis of the tube.          The ridges are located at least in the regions adjacent the ends of the spacer tube thereby, in use, to provide for locking engagement with teeth on the arms of corner pieces when inserted endwise into the ends of the spacer tube.  The base is shaped in cross-section so as to define a crest projecting a short distance into the interior of the hollow spacer tube with the transversely disposed ridges being formed in the crest.          The arms of the corner piece are disposed at right angles to one another and they are shaped to fit snugly into adjacent ends of the spacer tubes.  Each arm of the corner piece has a face portion disposed in close proximity to the base of the associated spacer tube when in use such face having rigid teeth thereon which interengage with certain of the ridges defined on the base of the spacer tube.
