Abstract: ABSTRACT OF THE DISCLOSURE     A plant for the gasification of fossil fuels which includes a reactor container and a further plant component attachable to the reactor container.  The reactor container has a discharge opening and includes a connection part extending outwardly from the discharge opening.  A fireproof lining, which determines the inner cross-sectional area of the container, is provided within the container.  An inter-mediate ring is interposed between the connecting part of the reactor  container and the further plant component for attaching the connecting part to the further plant component. This intermediate ring is provided with a fireproof lining having an area of reduced inner cross-section which is less than the inner cross-sectional area of the fireproof lining of the reactor container, the area of reduced cross-section being the smallest cross-sectional area in the connection between the reactor container and the further plant component.

Abstract: ABSTRACT         A roller pump particularly adapted for use in medical applications in which one or more hoses is compressed against an arcuate stator bearing surface by a plurality of rollers carried by a rotating rotor.  The hoses define a fluid passage and are configured so as to reduce the amount of force necessary to close the internal passage.  In this manner, leakage is greatly reduced or eliminated without requiring excessive force.  In a preferred embodiment, the fluid passage is defined by first and second sidewalls which are generally spaced from each other and joined at first and second apices.  Specifically, the sidewalls may be arcuate and, more specifically, elliptic with one of said sidewalls being positioned along the stator bearing surface with the other sidewall being engaged by the rotor during hose compression.  Tabs may also be provided to extend from the apices for positioning of the fluid passage within the path of the rotor.

Abstract: ABSTRACT OF THE DISCLOSURE     A urinal having a semi-rigid housing is useable by either a male or a female to receive urine discharged by a person whether in a seated or in a supine position.  A cappable opening to the collector includes a spout configured to receivingly support a penis when used by a male and the combination of the spout and opening is configured to develop a seal extending from the vaginal opening to a point above the urethra to prevent urine seepage then used by a female.  Opposed sides of the collector are concave to mate with the curvature of the user's thighs and help maintain the urinal in place during use.  A specially configured handle at the upper rear end of the housing aids in manipulating the urinal into and out of position of use and in minimizing the danger of inadvertent tipping.

Abstract: ABSTRACT OF THE DISCLOSURE     An electronic control means utilized in an electrically actuated shift apparatus for a multi-speed axle including an electric power source and an electric motor coupled to actuate means for shifting the axle.  The power source is connected to the electric motor through a shift speed control switch and a plurality of steering diodes.  When the switch is actuated to select an axle speed, power is applied through one of the steering diodes to one side of the armature of the motor.  Power is also applied through another of the diodes as a shift signal to a timing circuit.  A first means is responsive to the shift signal for generating a first control signal for a first predetermined time.  At the termination of the first control signal, the timing circuit generates a second control signal to connect the other side of the motor armature to ground thereby actuating the motor. The timing circuit generates the second control signal for a second predetermined time which is greater than the time required to shift the axle and less than the potential burnout time of the motor.  At the end of the second prede-termined time, the second control signal is termi-nated and the motor is disconnected from ground potential to discontinue current flow through the motor armature.

Abstract: ABSTRACT OF THE DISCLOSURE        A sonic treating apparatus in which sheet material is immersed in a shallow tank between sonic vibrators along opposite parallel sides thereof, which vibrators produce a horizontally sonic vibrating treating liquid in the tank. The sheets to be treated are supported with their planes horizontal and conveyed in this horizontal plane through the treating liquid transversely of its sonic vibrations so that two opposite edges of the horizontal sheets pass along and adjacent to the sonic vibrators. The conveyor may comprise a treating-liquid-resistant sprocket chain conveyor upon which the sheets rest. The sonic vibrators vibrate at a preset frequency between about 18 and 50 kilohertz and preferably between about 20 and 27 kilohertz. The treating liquid usually is for cleaning the sheets and may be an acid pickling solution for steel or phosphate coating solution, and the solution may be maintained at a predetermined elevated temperature by circulation through a heat exchanger. The temperature of the treating liquid, the concentration of the treating liquid, and the duration of the treatment are interdependent and are materially reduced from the conditions normally employed for such treatments without sonic vibrations.     - 1a -

Abstract: METHOD OF SEISMIC EXPLORATION    Abstract A seismic data compression technique comprises sampling each individual seismic trace, operating upon a set number of samples to generate a predicted sample, quantizing the difference between the next sample and the predicted value of the sample, and storing and/or transmitting the quantum number so that the amount of information which need be stored and/or transmitted is limited.  In a preferred feature, a linear prediction differential pulse code modulation scheme is used to provide the predicted value, while an adaptive quantization scheme is used to quantize the error value to be transmitted, thus yielding further improvements in accuracy.  A feedback loop can be applied to the decompression operation to limit quantization noise and further improve the fidelity of representation of the decompressed signals.

Abstract: SEAT INTERLOCK FOR SKID-STEER LOADER                 ABSTRACT OF THE DISCLOSURE           A seat interlock mechanism for a skid-steer loader is disclosed wherein the boom structure can be rendered inoperable for vertical movement if the opeator leaves his seat.  The hydraulic circuit for powering the hydraulic cylinders, which move the boom structure in a vertical direction, includes a solenoid valve that is capable of stopping the flow of fluid through the hydraulic circuit and, thereby, prevent the boom structure from vertically moving.  An improved seat frame structure, incorporating a switch which senses the presence of an operator on the seat, provides greater sensitivity for the presence of the operator, so that the switch can control the solenoid valve to stop or permit the flow of fluid through the circuit.  The improved seat frame includes a first member mounted to the loader frame and a second member biased away from the first member by a spring positioned beneath the center of gravity of that portion of the seat being biased upwardly by the spring.  The second member is connected to the first member by a plurality of bolts forming pivot axes forward and rearward of the spring.  The switch signals the presence of an operator in the seat when the second member moves towards the first member and engages the switch by the weight of the seat and the operator exceeding the upwardly biasing force of the spring.

Abstract: DIGITAL PHASE/FREQUENCY LOCKED LOOP            ABSTRACT OF THE DISCLOSURE   A digital extended linear phase range phase-frequency detector is applied in a phase locked loop to provide a low noise frequency spectrum output and a fast acquisition time.  This phase-frequency detector comprises a differential latch, an up/down counter and a digital to analog (D/A) converter. The D/A converter may be a resistor network type or a digital frequency rate multiplier.  The loop provides a large pull-in range and locking range.  The initial acquisition can be further aided by external logic or processor control. If phase error is not considered, the circuit can be arranged as a frequency locked loop.  An input frequency to be tracked is applied to the count-up input of the counter.  The D/A converter receives the counter's parallel output and provides an analog signal representative of the counter value.  The analog signal is filtered and applied to a voltage controlled oscillator, the output of which is applied to the count-down input of the counter.
