Abstract: ABSTRACT OF THE DISCLOSURE The system encodes a high rate digital video signal conveying the picture elements into a low rate digital signal conveying words representative of some picture elements. It comprises a frame store, a movement detector for detecting the movement area in one frame with respect to the preceding one, a predictor, a bit distributing circuit for selecting the picture elements to be transmitted, a PCM encoder , which encodes the DPCM words of the selected elements according to a quantization law and an interpolating circuit The number of bits NB allocated to each line in the low rate digital signal is made constant. The movement detector detects the two ledge elements defi-ning each line moving area and thereby deduces the maximum number NP and average bit number B of the element words to be encoded and transmitted. The bit distributing circuit down-counts the bits which remain for allocation to the line and the element words which remain likely to be encoded and compares these down-count totals for selectively controlling the encoding of moving area element word. A transmitted and encoded word represents the level number with respect to the quantization law associated with the line.

Abstract: Docket R4159 EAO:lhw               APPARATUS FOR GENERATING CONSTANT-ENVELOPE, ANGLE-MODULATED PULSE SIGNALS     ABSTRACT     An improved constant-envelope, angle-modulated pulse signal generator makes use of first and second bi-phase amplitude modulators, each for modulating a carrier with supplied pulse signals. The pulse signals are representative of information and are interleaved with each other. The pulse duration is selected to cause a suitable amount of pulse overlap. When the modulated carriers are combined in phase quadrature and passed through a surface acoustic wave filter, they form a constant envelope signal. Appropriate selection of parameters can yield a sinusoidal frequency shift keyed (SFSK) signal.

Title: Extrusion die head and method of making the same
Inventor: FETCHU DAVID C
IPC: B29C48/32
Filed: 1980-10-14
Granted: 1982-08-31
Abstract: GT-172? 0282? ABSTRACT OF THE DISCLOSURE A new extrusion die head and method of making the same is provided that permits two strips of elastomeric material to be extruded simultaneously and one above the other from a single core of extrudate. The head is particularly useful for extruding sidewall strips in the manufacture of pneumatic tires. The head design has features common to both conventional strip extruding heads and to heads for extruding tubular shapes, commonly called tuber heads. However, the head is quite different from both the conventional strip extrusion heads and the conventional tuber heads, and has the advantage that it permits two strips to be extruded simultaneously through passages that are relatively short in length and are no wider than the width of a single sidewall strip. The design of the head and the method of making it are such that the extrusion passage surfaces can be easily machined to provide excellent flow characteristics, and the entire head is easily fabricated and cleaned.

Abstract: 39/014) ABSTRACT OF THE DISCLOSURE        The method comprises covalently binding an immuno-reactive to a selected macromolecular carrier and then contacting the resulting hapten-carrier conjugate at a selected concentration in a liquid phase with a selected solid phase until a desired amount of the hapten-carrier conjugate is adsorbed to the surface of the solid phase.  Unbound hapten-carrier conjugate is then separated from the solid phase, and the solid phase containing the bound hapten-carrier conjugate is recovered for use in quantitative immunoassays and the like.  The solid phase can be, for example, surfaces of a test tube or microtiter well or the like.  The method is simple and inexpensive and permits hapten assays of improved sensitivity.

Title: Control circuit for current to pressure converter
Inventor: FRICK ROGER L
IPC: B05B12/00
Filed: 1980-11-14
Granted: 1983-08-23
Abstract: A current-to-pressure converter receives an electrical input signal, such as a DC current, which is a function of a sensed parameter and which is indicative of a desired output pressure. An electrical-to-pressure transducer provides an output fluid pressure as a function of an electrical control signal. A function of the output pressure is sensed by a sensor which provides an electrical feedback signal which is a function of such pressure. The feedback signal is compared to a command signal derived from the electrical input signal. When a change in the sensed parameter occurs, the electrical input signal changes, which in turn results in a change in the command signal. The electrical control signal changes, thereby changing the output pressure until the feedback signal has changed sufficiently to return the command signal and feedback signal to a balanced state.

Abstract: ABSTRACT         The cracking of crude oil or crude oil resi-dues is accomplished in an adiabatic reactor which fol-lows a partial combustion zone with the injection of superheated or shift steam into the combustion gases.     The advantages obtained are that the carbon monoxide produced by partial combustion is converted to carbon dioxide which is easily removed, there is no need to supply a separate source of fuel or hydrogen, and coke formation is substantially eliminated.  The cracked oil produced in the process can be used as a quench oil and/or fuel to feed the partial combustion zone.  The yields of olefins, especially ethylene, and aromatics is increased over processes using only superheated steam cracking.   18,442B-F            -20-

Abstract: ABSTRACT OF THE DISCLOSURE    A  circuit breaker has contacts engageable as a result of manual operation of a toggle mechanism causing the circuit breaker to close and open when the toggle is in an erect and collapsed condition, respectively.  A push-off spring is used to bias a moveable contact away from a stationary contact to accelerate movement of the moveable contact during opening of the circuit breaker.  Minimal manual effort is required to close the circuit breaker while providing greatly increased pressure for accelerating opening of the circuit breaker through use of a unique push-off spring which provides a first, lower, degree of resistance to closing of the contacts during the initial operation of the circuit breaker while providing a second, higher, degree of resistance to closing of the con-tacts after the initial operation.  Manual closing of the circuit breaker is unimpeded by the second, higher, degree of resistance after the initial operation of the breaker.
