Abstract: ABSTRACT OF THE INVENTION A nuclear imaging system includes an analog signal processor which features analog data derandomization for minimiz-ing data loss due to pulse pile-up.  A scintillation detector provides a sequence of analog data pulses to the signal processor, the data pulses characterizing the energy level and situs of respective radiation events striking the detector.  The signal processor includes sets of novel peak detectors and of sample and hold circuits which are serially connected and are operated to derandomize or space the sequence of analog data pulses so that the system can process pulses corresponding to photopeak events occurring only 1.5 microseconds apart.  The analog data pulses are stored in analog pulse form in the peak detectors and are selectively transferred into the sample and hold circuitry from which they are transferred to the display mechanism.  The signal processor is multiplexed with several data input channels for accommodating dual isotope operation.  A control unit is provided which controls the data processing cycle according to a predeter-mined processing time, or according to signals from external system apparatus. The control unit provides automatic resetting for assurance that the signal processor does not become locked into an inoperative, nondata processing state.  The novel peak detectors are controlled by the control unit and feature input biasing for increased detection sensitivity, proportional dumping for discharging the stored peak value at a rate proportional to the value of the stored peak, and selective input data gating so that only the peak containing portion of the input signal is input into the detector.

Abstract: Abstract A two-vessel continuous reactor system is used to make a uniform acrylonitrile copolymer containing 65 to 85% by weight acrylonitrile polymerized units and 35 to 15% by weight of styrene polymerized units.  Into a first reactor are fed a free radical initiator together with an emulsified feed containing acrylonitrile, styrene and a chain transfer agent.  Formation of polymer seed particles takes place in the first reactor and an outlet stream is continuously introduced into a second reactor together with added free radical initiator and a second aqueous emulsified feed containing acrylonitrile, styrene, and a chain transfer agent to continue growth of the seed particles.  Conditions of particle initiation in the first reactor as opposed to particle growth in the second reactor are carefully separated to obtain noncyclical operation with low levels of coagulum formation in both reactors together with a final low emulsifier content in the polymer.           The acrylonitrile copolymer is useful for articles where barrier properties are desirable to retard passage of oxygen, carbon dioxide and water vapor, e.g., carbonated beverage bottles.

Abstract: COMBINED STEERING AND BRAKING   MEANS FOR CRAWLER TRACTOR                        A B S T R A C T           A crawler tractor has an engine-driven fluid power shifted transmission for supplying motive power to left and right crawler tracks through spring-applied fluid-released left and right steering clutches and also has spring-applied fluid-released brake actuators for the track brakes.  A hydraulic control system for steering and braking the tractor includes a combined steering and braking valve having a pair of lever operated valve spools, a shuttle valve, and a supplemental brake control valve operated by a single brake pedal.  The combined steering and braking valve, which includes a flow divider, directs fluid from a pump to the brake actuators to maintain the brakes released when the valve spools are in neutral.  When a lever operated valve spool is moved from neutral to some other position, the combined steering and braking valve directs fluid to disengage a clutch and causes the brake for the associated track to be applied.  The combined steering and braking valve operates to regu-late fluid pressure in the system and also operates to ensure that sufficient fluid pressure is available for clutch operation regardless of brake actuator demands.  The shuttle valve is connected to the brake actuators and is responsive to the supple-mental brake valve to apply either or both brakes when the supplemental brake valve is actuated either by the brake pedal or in response to a drop of fluid pressure in the power shift transmission.
