    摘要: 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.

    摘要: 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.

    摘要: 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. The part of the first portion that projects from the engine is short with respect to the part that fits into the engine. The projecting portion carries wrench-engaging bosses.

    摘要: 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.

    摘要: 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.
