Abstract: ABSTRACT OF THE DISCLOSURE           A positron imaging system and method in which two opposed Anger cameras are employed on opposite sides of an organ to be imaged.  The cameras include a planar unitary scintillation crystal approximately 2.5 cm. in thickness, and the electronics which process the signals from the cameras include pulse shaping circuitry to reduce both the duration and the integration time of pulses resulting from radioactive events.  Both cameras exclude collimators to enable radiation incident upon them at many angles to be accepted, and means are included to rotate the opposed cameras about the organ of interest to enable transverse tomographic imaging.

Abstract: Abstract of the Disclosure A polymer latex is coagulated by passing the polymer latex and a coagulant through a screw-type extruder in which the latex and coagulant are mixed and mechanically worked under pressure by a rotating interrupted worm flight in cooperation with a plurality of stationary breaker members.  At the down-stream end of the extruder, the coagulated polymer is compacted and extruded.  The extruded polymer is characterized by relative-ly low moisture content, and the excess process liquid which drains from the compacted polymer is relatively free of un-coagulated polymer.

Abstract: ABSTRACT OF THE DISCLOSURE         A switch mechanism senses the rotational direction of a rotating member so that reversal of direction acts through a control switch to energize or de-energize an electric circuit.  The mechanism has a reciprocable switch actuator frictionally engaging the rotating member, whereby rotation of the rotating member in one direction pulls the actuator and rotation in the other direction pushes the actuator to operate the control switch.  The rotating member may be a shaft, or it may be an idler wheel driven by the shaft, so that the rotational direction of the shaft is sensed and actuates the control switch.  Herein, the switch mechanism senses the rotational direction of an output shaft in an escalator drive train.  Accidental loss of motor torque when the escalator in in the "up" mode may permit reverse rotation of the output shaft as the escalator starts down under the weight of the passengers, but actuation of the control switch drops the up direction contactor and sets a brake.

Abstract: Abstract of the Disclosure A nonlinear hydraulic pump control provides a primary control output as a mechanical actuator arm displacement either side of a neutral or "Off" position.  A secondary control, also cam activated, operates in selectable offset sequence with the primary output, with the offset magnitude being selectively adjustable and effected either symmetrically about the primary control neutral position or differentially with respect thereto.  The secondary control is useful in starting, stopping, or modulating accessory gear which cooperates with the pump operation, such as brake release control for a hydraulic winch to assure controlling hydraulic pressure buildup prior to brake release for both inhaul and outhaul operations where the winch cable is constantly subjected to tension loading.

Title: Extraction of antimony from antimony sulfides bearing  solids
Inventor: VOGT JOHN W
IPC: C01G30/02
Filed: 1978-03-22
Granted: 1981-05-19
Abstract: ABSTRACT OF THE DISCLOSURE       A method for extracting antimony from solids containing antimony sulfides is described.  An improvement in the method of extracting antimony by oxidation of an aqueous mixture of the solids in an acid or by oxidation of a leaching liquor obtained by leaching the antimony from the solids with an aqueous basic solution comprises conducting the oxidation in the presence of a catalyst comprising a water-soluble copper salt, a quinone, a hydroquinone or mixtures of one or more of these.  The catalyst significantly increases the rate of oxidation and the rate of the recovery of the antimony form antimony sulfide bearing solids, particularly natural ores.  Where the oxidation is conducted in a basic solution, the antimony is recovered as pentavalent antimony in the form of metal antimonates.  Facile reduction of the metal antimonate to antimony trioxide also is described.

Abstract: SELECTIVE CONDENSATION PROCESS AND CONDENSER APPARATUS     ABSTRACT OF THE DISCLOSURE            Contaminant substances having high biochemical oxygen demand, foul odors, etc., are often carried by vapors to be condensed in industrial processes.  Certain of these contaminants are more volatile than the primary constituent of the vapor to be condensed.  The invention concerns a process and apparatus for separating most of the more volatile contaminants so that separate streams of condensate are produced, one of which is relatively clean while the other stream, though considerably smaller in volume, carries most of the contaminants.  A plate type surface condenser having a barrier on the condensing side which prevents the passage of contaminants into a stream of relatively clean condensate is disclosed.  In case several different streams of condensate are to be separated, the condenser apparatus has several sections arranged in series.

Abstract: MANUEL DEE MILLS                    DYNAMOMETER FOR MONITORING    SUCKER ROD STRINGS      ABSTRACT A dynamometer for monitoring the tension in a pair of spaced, elongated members.  A pen, actuated by a sensor means, measures the tension in the pair of spaced, elongated members, and places indicia upon a continuously moving chart.  The indicia is related to the magnitude of the measured tension and is in the form of spaced-apart, individual curves or plots.  Hence the pen contacts the chart for a first time interval; and thereafter, the pen is lifted from the chart for a second time interval so as to cyclically place the indicia upon the chart at successive inter-vals of time.  More specifically, the dynamometer measures the tension in a rod string.  The rod string is reciprocated by a pumpjack unit located above the ground and drives a downhole pump. The dynamometer therefore cyclically measures the pumping charac-teristics of the well at successive, predetermined intervals  of time and provides a permanent record which can be stored and sub-sequently consulted in order to determine the characteristics of the entire pumping unit over a projected interval of time.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for measuring the set pressure of a safety valve coupled to a pressure line, where the valve includes a springloaded closure element which is normally biased to close a port of the pressure line.  The device includes a position transducer which generates a signal representative of the closure element position with respect to the port.  In addition, a forcer is selectively operable to apply a force ramp to the closure element in the direction opposite to the springloaded bias.  A force transducer generates a signal representative of the force applied to the closure element.  A measurement cycle controller controlls the measurement operation initially to activate the forcer.  During the application of the force  ramp to the closure element, a test time is identified.  This test time occurs to mark when the closure element has moved a pre-determined distance from its port position.  At the test time, the controller detects the current pressure within the pressure line and the force currently applied to the closure element by the forcer, and then uses those detected values to generate a signal representative of the set pressure of the valve.
