Patent CA-1095112-A (CA)
Inventor: BOTTE ANTHONY J

Abstract: Abstract A copy production machine having a document feed and a collator controls collator operation for optimum performance in accordance with the status of the original document feed.  The collator has a con-struction such that collation of a moving vane in a first relative direction with respect to a set of collator bins provides more reliable collation operation for enhancing throughput.  When an original document is in a position to be copied upon the ending of a current copy production run, collation occurs in both directions of relative motion, whereas in the absence of such original document in the document feed position, collation only occurs in the preferred direction.  In other aspects of the invention, whenever copies from multiple images are simultaneously being processed by the copy production machine, collation occurs in both directions of collation, whereas when copies bear images of a single image then collation only occurs in the preferred direction.

Abstract: AN EXHAUST BRAKING VALVE          Abstract of the Disclosure An exhaust braking valve is provided for use on an internal combustion engine having an exhaust manifold and a turbocharger associated therewith.  The braking valve comprises a hollow section having an inlet communicating with the discharge side of the exhaust manifold and an outlet communicating with the intake for the turbine section of the turbocharger.  Disposed within the hollow section is an adjustable member having a flow passage formed therein which, when the member is in a selected first position of adjustment, interconnects the inlet and outlet and effects unrestricted gas flow through the valve.  When the adjustable member is in a selected second position of adjustment, a segment thereof assumes a gas flow blocking relation with respect to the inlet and outlet of the hollow section.  The segment of the adjustable member is provided with bleeder means whereby, when the segment is in the gas flow blocking position, a sufficient amount of gas will flow therethrough to maintain rotation of the turbine wheel while a predetermined engine braking back pressure is maintained within the exhaust manifold.

Abstract: ABSTRACT OF THE DISCLOSURE        Silicon platelets essentially free of iron are precipitated from a solution of metallurgical grade silicon in molten aluminum and are melted in contact with silica slag to produce a refined metallurgical silicon (RMS).  Multigrained bouler of said RMS may be pulled by the Czochralski method on a rotating silicon seed rod from a melt of said RMS.  Alternatively, the silicon-slag melt can be directionally solidified to produce a directionally solidified refined metallurgical silicon (DS/RMS) separated from a region of solidified melt having a high concentra-tion of impurities rejected by the silicon as it solidifies, Multigrained DS/RMS boules may be pulled from a melt of said DS/RMS.  Alternatively, the DS/RMS is remelted and directionally solidified a second time with single crystal DS/RMS boules being pulled from a melt of the twice directionally solidified material.  The thus-pulled, jul multigrained RMS and DS/RMS and single crystal DS/RMS materials are low-cost products having a substantially higher impurity content than in conventional high purity semiconductor grade silicon while, at the same time, having desirable solar cell properties.

Abstract: A B S T R A C T     For feeding short rods, which term shall include tubes, such as clinical thermometer tubes with bulbs at one end, a feeding hopper has downwardly-converging bottom walls terminating in an elongated gap between their lower edges forming an elon-gated slot. Reciprocable horizontally beneath the slot is a fluid-pressure-operated ejector plunger which feeds, one at a time, the short rods to a horizontal receiver composed of a pair of spaced parallel guide bars separated by a distance large enough to pass the rod but to detain the bulb, whereupon the rod pivots around the detained bulb to swing downward into the slot and comes to rest between the bars with the bulb uppermost and the rod suspended vertically from the bars. Agitating mec-hanism including a pair of alternately-reciprocable agitator slides mounted side by side in spaced relationship beneath the gap closely select and receive the rods one at a time by moving upward and downward through the slot, and also intermittently shakes the stack of rods in the hopper so as to force them into mutually parallel horizontal positions, thereby preventing jam-ming of the rods in or arching together above the slot.

Abstract: ABSTRACT            Therapeutic waistcoat for the treatment of ailments in the cervical and neck-arm region, e.g. cervical syndrome, omarthrose, peri-arthritis. The waistcoat tightly encloses the entire upper part of the body and has a collar part at least twice as long as the neck. The collar folds down to form a stiff collar; if desired, an additional neck support may be inserted into it.  With or without additional neck support, the collar is dimensioned in a way to assure contact pressure by the collar part on the entire neck region up to the jaw and the base of the skull. The fabric of the waistcoat, including the collar part, consists of an electrostatically active knit made of a mix of polyvinyl chloride and acrylic fibres. The supporting effect applied in the neck region in combination with the increased heat effect caused by the contact pressure results in a therapeutic effect in the cervical range which radiates to the areas of the shoulder and elbow joints.
