Abstract: METHOD OF UNIFORM INDUCTION HEATING      OF AN ELONGATED WORKPIECE     (Abstract of the Disclosure) A method for uniformly heating an elongated workpiece having a first portion with uniform cross-section over a major portion of the workpiece length and a second portion having a larger cross-section than the first portion.  A multi-turn inductor is operatively mounted on a carriage or the like and is coaxially disposed about an elongated workpath.  The carriage is selectively movable axially of the workpath from a first or home position.  As the workpiece first portion is fed along the workpath at some preselected rate of travel into and through the inductor, it is heated to a desired temperature over the length thereof.  The inductor carriage is energized as the enlarged workpiece second portion enters the inductor so that the inductor will travel along the workpath with the workpiece.  Such travel increases the heating time for the second portion so that it too is heated to the desired temperature.  After a predetermined time interval, the carriage movement is reversed back toward the first or home position.          The method is adapted to use with workpieces having plural enlarged areas spaced therealong and is adaptable to simultaneous heating of a plurality of workpieces with plural inductors.

Abstract: AMMONIUM TEST     ABSTRACT OF THE DISCLOSURE           Diammonium phosphate (DAP) and ammonium sulfate are quite commonly used in a mud system generally known as the DAP mud.  The function of these products is to in-hibit shale hydration by the ammonium ions.  The ammonium test utilizes the same principle known as the Nessler's ammonium test in which an alkaline potassium iodide and mercuric chloride solution is used.  However, the method has been modified to accommodate much higher ammonium ion concentration and a simple color-wheel method is used to determine the color intensity of the test solution.  The method is applicable to DAP concentration between 0 -15 lbs/bbl (0 - 45 kg/m3).  DAP is rarely used in higher than 12 lbs/bbl in mud systems.

Abstract: ELECTRONIC CONTROLLER FOR VALVE ACTUATORS                  Abstract Of The Disclosure An electronic controller is provided to control the energization of an electrical actuator to readjust a valve which controls the flow of a fluid in a controllable process. The controller is responsive to two signals, one of which is produced by a process sensor to represent the instantaneous magnitude of a predetermined process parameter and the second of which constitutes a set signal representative of a desired magnitude of the parameter.  The signals are compared, and the sense of any resulting error signal is used to control the direction of movement of the actuator while the instantaneous magnitude of the error signal, during a succession of equal time intervals, is used to control the rate of movement of the actuator by controlling the extent of movement of the actuator during each of the time intervals.  The actuator is jointly responsive to these two controls and moves in a series of incre-mental steps, the sizes of which decrease exponentially to match the process loop variable's exponential change with time, as the error signal reduces to zero.

Abstract: STEERING BRAKE AND CLUTCH CONTROL    Abstract of the Disclosure A steering brake and clutch control for a crawler vehicle includes a pair of primary control levers, each of which, when operated by itself, acts through a spring to first effect dis-engagement of normally pressure-engaged clutch and then through a linkage to effect engagement of a brake.  The clutch control levers are interconnected so that simultaneous actuation of the primary control levers results in both brakes being engaged without the clutches being disengaged.  A pair of brake control levers have respective one-way connections with the pair of primary control levers and are spring-biased for simultaneously actuating the primary control levers to effect brake engagement. A pressure-operated plunger assembly is operative to maintain the brake control levers away from the primary control levers so long as sufficient hydraulic system pressure exists for normal operation.

Abstract: ABSTRACT OF THE DISCLOSURE     Door-swing restraint apparatus for a pair of latched doors closing an end opening of a cargo box comprises a chain or cable link connected between margins of the doors so that a person actuating a bar to release door latches will not be injured by freight items which bear against the door.  One end of the link is fixed near the marginal edge of one door, the other end being fixed to a lever arm which can be selectably engaged with or disengaged from a lateral bracket on the latch bar of the other door, only when the arm is rotated out of its horizontal transport position into the vertical. Rotation of the bar caused by torque resulting from outward force on the door is limited by a stop pin carried by the bar engaging a slot in a door-mounted journal.  Opening swing of the unlatched door is thereby limited to a few centimeters, the link being made taut and the lever arm remaining horizontal as a visual signal of the hazard.         Disengagement of the lever arm from the bracket is effected by first turning the arm down, then sliding a pivot pin relatively to a slot of right-angle form; in one embodiment the bracket sidewalls carry a fixed transverse pin and the arm is slotted,while in a second embodiment the arm carries the pin and the bracket sidewalls are slotted.

Abstract: SPEECH RECOGNITION METHOD AND APPARATUS                    ABSTRACT OF THE DISCLOSURE         A speech recognition method and apparatus for detecting and recognizing one or more keywords in a continuous audio signal is disclosed.  Each keyword is represented by a keyword template which corresponds to a sequence of plural target patterns, and each target pattern comprises statistics representing each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio.  The spectra are processed to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into multi-frame spectral patterns and are compared by means of likelihood statistics with the target patterns of the keyword templates. Each multi-frame pattern is forced to contribute to the total score for each keyword as represented by the keyword template. A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.
