Abstract: A sandal has separately adjustable toe and ankle strap assemblies. The toe strap assembly has a toe strap which is permanently secured at one end thereof to one side of the insole of the sandal. An anchor member is secured to the under surface of the insole at the side thereof opposite to that at which the strap is secured. This anchor member has an upright portion with a lateral slot formed therein, this upright portion being fitted in a slot in the insole and recessed below the upper surface of the insole. The toe strap is wrapped over the wearer's foot and slidably fitted through the slot in the anchor member and then folded over on itself, a hook-loop fastener installed on opposing strap portions being employed to firmly hold the strap in position. The heel strap assembly has a pair of straps, one of which wraps around the wearer's foot directly behind the instep, the other of which wraps around the wearer's heel. Both of these straps are permanently attached at one end thereof to one side of the insole.

Abstract: An original film or video sound track and a translation of this sound track into another language are separately recorded and a predetermined positioning timewise relative to the original sound track introduced to the output of the translation to make for best clarity and understanding of the two audio outputs when they are superimposed. The audio levels of the original sound track output and the translation are then set to predesired levels and combined with each other. The combined signal is then fed to an audio compressor which is triggered by an attack signal generated by a second recording of the translation which is advanced in time by 0.5-2.0 seconds relative to the first translation recording. The combined original and translation audio signal is thus ramped down to a lower level a predetermined time period before and during the time the translation audio is present, the sound track level being restored to its original audio level a predetermined time period after the translation audio has stopped.

Abstract: The throttle of an aircraft can be alternatively controlled either by a flight control computer or by the manual control of the pilot. A clutch is installed between the throttle control lever and a control input to the flight control computer which in the autothrottle mode of operation is engaged to enable control of the throttle by the flight control computer with the control lever being positioned in accordance with such control. When manual takeover of the throttle control is desired, a switch is actuated by the pilot which operates to disengage the clutch and thereby disconnects the control output of the computer from the lever so that only manual control is provided. A unique clutch mechanism is employed which utilizes a pair of locking wedges which operate in conjunction with a pair of rollers. The wedges and rollers are driven into engagement with each other by a solenoid, the opposing plates of the clutch being held in locking engagement through the intermediary provided by the wedges and rollers.

Abstract: A light assembly has a light unit mounted within a housing having a front portion with a lens for passing light from the light unit, a side portion with ventilation channels formed therein and a rear portion which completes the enclosure of the light unit. The ventilation channels in the housing side portion are formed by a plurality of fins formed by strip sections which are spaced from each and which have lips running along the inner edges thereof which extend at an obtuse angle relative thereto. The fins are joined together to form an integral unit with the channels running completely around the housing. The channels formed between the fins permit a free flow of air for ventilating the interior of the housing. The fins are angled away from the center of the housing so that along with the lips running along their inner edges such fins operate to minimize the passage of light through the housing side portion.

Abstract: A discrete parallel path modulation multiplexer for use in generating a composite baseband signal from separate left and right input signals. The composite baseband signal includes the sum of the left and right input signals and the product of the difference between the left and right input signals and a subcarrier. The composite baseband signal may also include a pilot subcarrier at one-half the frequency of the subcarrier. In one signal path, the multiplexer multiplies the right input signal by the function (1+sin (wt)) and in a second signal path the multiplexer multiplies the left input signal by the function (1-sin (wt)). The products are then combined to obtain the composite baseband signal. A pilot subcarrier may also be generated and included as part of the composite baseband signal.

Abstract: A device having pop-out wings and a guidance and control system is detachably mounted on a munition such as a bomb and is used to extend the range capability of the munition. Prior to launch, the wings are folded together. The control system is contained within a saddle portion of the device, and when the munition is released from the aircraft, the wings are caused to pop out to their flying position. The saddle is secured to the munition through a single bolt. Controllable flaps are installed along the trailing edges of the wings, such flaps being operated to control the pitch and roll angle of the munition. When the target area is reached, the device is jettisoned by detonating a charge which shears the securing bolt, thereby permitting the device to pivot rearwardly and separate from the munition.

Abstract: A golf putter head has a pair of spaced notches formed in the top surface of the face plate thereof. These notches run through the face plate transversely and have a width and depth suitable for removably receiving golf tees or the like in retention therein. With golf tees installed in each of the notches, such tees form spacers extending normally from the face plate, the distance between such spacers being such as to receive a golf ball therebetween with a small space to spare on either side of the ball. The golfer practices putting by striking the ball on the surface area of the face plate without the ball striking either tee. The tees are readily removable when the putter is used for actual play.

Abstract: An electrically conductive diaphragm is sandwiched between a first and second board member. One of said board members has a metallic plate thereon, there being a non conductive spacer having an opening therein separating such board member from the diaphragm. The board members, diaphragm and spacer are joined together to form an integral assembly, the portion of the diaphragm opposite the opening in the spacer being free to move in such opening towards the board member with the metallic plate, motion of the diaphragm away from the spacer being prevented by the other board member. A respiratory gas inlet is provided through the board member with the metallic plate to the opening in the spacer. The diaphragm and metallic plate form a capacitor the capacitance of which is varied in response to the pressure differential between the gas inlet and the atmosphere, the diaphragm only being free to move towards the metallic plate in response to negative pressures (suction) induced during inspiration by a patient.

Abstract: An electronic power factor corrector for a main equipment is employed to correct the power factor of an accessory to the main equipment. A voltage signal is generated in accordance with the rectified current input to the accessory. This voltage signal is summed with a voltage signal in accordance with the sampled input current or the current in the return current path from the main equipment. The summation signal is fed to a differential amplifier where it is compared with a reference signal in accordance with the current input to the main equipment. The output of the differential amplifier is fed as a control signal to a switching current source circuit which controls the current drawn by the main equipment and accessory to maintain the power factor close to unity.

Abstract: An elongated cylindrical club portion has a hand guard which with the handle of the club portion forms a generally rectangular configuration at one end of the baton. The hand guard includes a trapping member forming an end wall of the guard which has a trapping tip extending beyond the hand guard perimeter. This trapping member is adjacent to and extends angularly towards the club portion and operates in conjunction with the club portion to facilitate the trapping of portions of an an opponent's body as well as bats and other such weapons. The handle further has an indentation formed therein to facilitate the gripping thereof. A side guard extends from the club portion handle. This side guard protects the user's hand and enables a more secure and more controllable grip. The side guard has a rotatable bushing installed therein which facilitates rotation of the baton. The side guard in conjunction with the rotatable bushing can be used to rapidly change the user's hand position on the baton as may be required.

Abstract: An improved aerodynamic vane is used for sensing the angle of attack of an aircraft during yawed flight. Left and right sensors are rotatably mounted to opposite sides of the fuselage of the aircraft and rotate in the air flow to a position indicative of the angle of attack of the aircraft. Each sensor consists of an arm rotatably attached at one end to the aircraft with a vane at the other end of the arm, which vane is canted at an angle with respect to the axis of rotation of the arm. The vanes on the sensors on the opposite sides of the aircraft are both canted down or up as to cause the sensors to take similar angular positions during yawed flight.

Abstract: An audio signal compression device which utilizes both a broad band compressor and a high frequency expander. The level of the compression provided by the compressor and the level of expansion provided by the high frequency expander are both controlled by a voltage or other signal that is output by signal level detection circuitry within the device. The broadband compressor provides a variable level of amplification (or attenuation) that is relatively uniform as a function of frequency. The high frequency expander provides a variable level of expansion wherein the high frequency components are expanded more than the mid and low frequency components.

Abstract: A strap assembly has one or more cleat members slidably installed on the strap portion thereof. These cleat members have projections thereon which engage the tread of the tire of a vehicle to be retained in position for transportation on a rail car or other transport. The opposite ends of the strap assembly are secured to the body of the transport. A ratchet buckle or other such device is installed in series with the strap and is used to tighten down the strap against the vehicle tire.

Abstract: An improved wind shear warning system for aircraft. A wind shear signal representing wind shear as modified by the downdraft drift angle of the aircraft is used to provide a warning signal when the wind shear signal exceeds (negatively) a variable threshold. The threshold for the warning signal is modified in response to the pilot controlled excess of the airspeed of the aircraft over a reference airspeed during the approach to a landing so as to avoid unnecessary warnings. The threshold is further altered when the wind shear signal during approach indicates the high likelihood of a reversal of wind shear conditions.
