Abstract: A surgical apparatus for use with a prosthetic holder to which a prosthesis is secured by sutures. The apparatus includes an elongated handle having a grip end and a coupler end and defining a first aperture extending along a length from the grip end to the coupler end. The apparatus can also include a first shaft at least partially disposed within the first aperture with a first actuator at the grip end and a holder coupling mechanism at the coupler end. The apparatus can have one of a second shaft and a sheath disposed along the handle with a second actuator at the grip end and a cutting element at the coupler end. A force applied to the first actuator enables one of engagement and disengagement with the prosthesis holder, and a force applied to the second actuator enables deployment of a cutting element to cut the sutures securing the prosthesis to the prosthetic holder.

Abstract: A hitch-mounted cargo carrier for a vehicle which includes a platform that can be selectively tilted downwardly to facilitate loading of the carrier. Upon loading the platform, the platform may be raised for transport of the load. The carrier includes a fixed frame which is removably mounted to the hitch. A pair of pivotable arms are attached to the frame. The other end of the arms are pivotably attached to the platform. A jack assembly associated with the frame pivots the arms to move the platform. The arms have different lengths such that pivoting movement cases one end of the platform to tilt downwardly.

Abstract: The tool includes a housing and a pair of forwardly projecting tubes respectively containing slidably mounted rods, one for use in tensioning a lock wire and the other for use in crimping a ferrule onto the lock wire. Camming structure moves the rods forwardly and rearwardly. First, the tensioning rod snaps back under the control of a spring to tension the wire. Then, the ferrule is crimped by forward movement of the other rod.

Abstract: The tool is a pliers or cutters having two members that are pivotally joined. The portions of the members on one side of the joint define cutter jaws or plier jaws as the case may be. On the other side of the joint, the members define handles located on the same side of the jaw axis. The rear handle has a first section nearest its associated jaw extending away from the jaw axis at an acute angle, and a second section extending from the first section at an obtuse angle. The other handle also has two sections, the first section nearest the jaws having a slight curvature and the second section having a curvature which is convex outwardly and is more pronounced than that of the first section.

Abstract: An engine timing apparatus includes a piezoelectric transducer and a device for mechanically coupling it to a fuel injector body of the engine. A 6-inch clamping-type pliers is clamped to the injector body. A metal housing is fastened to the pliers at the jaw pivot, the housing having a cylindrical side wall and a circular bottom wall in positive contact with the pliers. The transducer is supported in a recess in a rubber sleeve in the housing and cooperates with the housing to define a resonant chamber at substantially 40 Khz. The dimensions of the pliers are such that the ultrasonic acoustic emissions of the injector body induce in the pliers a standing wave at substantially 40 Khz or a harmonic thereof, the jaw pivot being disposed substantially at an antinode, or point of maximum displacement, of the standing wave. The housing above the transducer is filled with an acoustically insulating foam and covered with a plastic cap.

Abstract: The adapter includes a luminosity probe for replacing the glow plug associated with the selected cylinder in a diesel engine, a timer circuit responsive to inception of each electrical signal generated by the luminosity probe to produce a timer signal. The timer signal is differentiated to produce a spike. A pickup loop receives the spike and produces an inductive signal for application to the clip of a spark-ignited-engine timing meter.

Abstract: The probe includes an elongated body having a reduced diameter portion at the front thereof. A light-transmitting tube is located in the bore of the body and abuts against the shoulder defined by the reduced diameter portion. A microwave conductor in the tube protrudes from the front end. A plastic tubular shield is located at the rear end of the body and is held in place by a sleeve encompassing both shield and the body.

Abstract: The luminosity probe includes an elongated tubular member having a bore extending therethrough. Within the bore is a light pipe having a diameter less than the diameter of the bore so as to create an annulus therebetween. Such annulus is filled with epoxy.

Abstract: The adapter includes a housing containing a rectifier for supplying flash voltages to an LED. The rectifier rectifies inductive signals derived from an inductive pickup. The adapter can be used to enable a spark-ignited engine calibrator to calibrate a diesel-engine-timing meter by converting the inductive electrical signals from the calibrator to light signals for the diesel timing meter. The adapter also can be used to enable a diesel-engine-timing meter and analyze and time a spark-ignited engine by converting the inductive pulses derived from a spark plug wire into light impulses for the diesel-engine-timing meter.

Abstract: The probe includes a tubular housing having a first portion and a second portion. The first portion is adapted to be mounted in place of the glow plug of a selected engine cylinder. A light pipe within the first portion directs light from the combustion zone to a phototransistor within the second portion. The front of the first portion has a reduced size aperture defined by an internal shoulder against which the front of the light pipe is seated. The rear of the first portion carries resilient sealing means which is deformed when the second portion is telescoped thereon so as to provide a detachable, frictional, light-tight thermally insulated connection therebetween. A phototransistor is mounted within the second portion to convert light passing through the light pipe into electrical signals. A cable carries these electrical signals to processing equipment. A base resistor is located in the second portion between the base of the phototransistor and the cable.

Abstract: A first signal at a first frequency which is a selected harmonic of the resonant frequency of a bolt in a first loaded condition is determined. Then there is determined a second signal at a second frequency being the same harmonic of the resonant frequency of the bolt in a second loaded condition. Both frequencies are multiplied by a factor M. The up input of a counter receives one of the signals for a predetermined duration, and the down input receives the other signal for the same duration. The number of pulses remaining in the counter is representative of the difference in load between the first and second loaded conditions.

Abstract: The apparatus comprises a luminosity probe to provide an electrical signal in response to the combustion event in a diesel engine and also comprises a probe to provide another electrical signal indicative of top dead center. Both electrical signals are processed and applied to a circuit which generates an output pulse having a duration corresponding to the time between the start of the electrical signals. A meter displays the angle represented by the duration of such pulse. Circuitry is provided to compensate for offset.
