Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus is utilized in the detection of certain characteristics in the speech of stutterers as they participate in a program which reconstructs the basic properties of speech sounds.          The method of speech therapy for stutterers includes transducing a patient's speech into an electrical signal and comparing the transduced signal to a reference signal representative of the desired speech target behavior. The comparison is initiated when the amplitude of the trans-duced speech signal exceeds a threshold related to a minimal sound level. When the amplitude of the transduced speech signal exceeds that of the reference signal, the subject is visually advised of an error in his speech. When the amplitude of the transduced speech signal remains above the trigger threshold and below the reference signal, the subject is visually advised that a correct speech response has been made. In a second embodiment, the rate of change of the amplitude of the subject's speech signal is compared with a reference related to the desired target behavior.

Abstract: DIFFERENTIAL PRESSURE POWER ROAD SPEED CONTROL SYSTEM            Abstract of the Disclosure A vehicle road speed control system in which the engine intake manifold pressure and the engine exhaust manifold pressure are utilized on opposite sides of a servomotor power wall to control the engine throttle and maintain a desired constant vehicle speed.  The intake manifold pressure is normally sub-atmospheric and the exhaust manifold pressure is normally super-atmospheric.  Within the usual operating range of vehicle engine loads, the pressure difference between the two pressures remains substantially constant and provides a more uniform pressure dif-ferential than that provided in systems in which atmospheric pressure is the higher of the two pressures.  The intake manifold pressure has a control valve in the conduit leading to the servomotor which varies the value of the pressure difference delivered to the servomotor in accordance with a control signal generated by a comparison of desired vehicle speed and actual vehicle speed.

Abstract: ABSTRACT        The invention relates to a method of guiding an under-water structure about a submerged, sound-reflecting object. A dual-ranging sonar is mounted on a surface craft that tows the structure.  The structure carries at least two spaced-apart, electro-acoustic transducers for consecutively transmitting sound beams into the body of water and for detecting the echoes of the sound beams for recordation by the sonar.  The beams are directed mostly downwardly and toward each other, and the records made by the sonar are used by the surface craft to maneuver the structure about the submerged object.  The records can be used to provide a continuous display of the position of the struc-ture relative to the submerged object.

Abstract: ABSTRACT OF THE DISCLOSURE                 An electro-thermal fluid displacement actuator includes a fixed volume boiler chamber and a variable volume actuation chamber formed by a ported partition being re-ceived in the main body of the actuator between a positive temperature coefficient heat source for the contained fluid and an elastomeric diaphragm.  Upon energization of the heat source, a portion of the contained fluid vaporizes to in-crease the pressure in the boiler chamber resulting in dis-placement of some of the remaining fluid through the parti-tion ports and into contact with the diaphragm to drive the same and the piston assembly mounted thereon through the predetermined stroke thereof.           A positive temperature coefficient heater for en-hancing the response time of thermal actuators is disclosed. The PTC heater is formed of a generally low resistance material that has an anomaly temperature above which the resistance of the heater increases dramatically.  The anomaly temperature is chosen to substantially match the phase change temperature of a thermally expansive medium useful to power the actuator.  The heater is self-regulating and provides a maximum surface area for heating the medium rapidly with a minimum of  thermal ? , and energy use. Preferably, the heater is formed of BaTiO3 in the general shape of an elon-gated annular cylinder.

A first clutch is rotat-ably mounted in the housing and a second clutch is rotatably mounted in the annular bearing member and movable relative to said first clutch be-tween a first position whereat the second clutch firmly engages the first clutch and a second position whereat the second clutch is disengaged from the first clutch. A spring biases the second clutch into its second posi-tion. The annular bearing member is movably mounted in the bore for engaging the second clutch member to counteract the urging force of the spring and to displace the second clutch from the second position into the first position. A face cam formed on the annular bearing member and a cam follower is located on the housing for coacting with the face cam to guide the annular bearing member when the same is moved along the bore to bring the second clutch into its first position. An annular collar mounted on the annular bearing member and spring loaded detent pins coact to hold the annular bearing member in place when the same has been moved along the bore and the second clutch is in its first posi-tion. The cam arrangement permits the operator of the tool to quickly shift the tool from one mode to the other mode of operation simply by rotating the annular bearing member through a small angle.
