A crimping tool with a crimping opening extending at an angle to the axial direction of the tool. The tool can include jaws with multiple crimping openings cooperatively defined thereby at different angles relative to the longitudinal axial direction of the tool. For example, the crimping openings can begin at a respective faces of the jaw and such faces can extend at different angles relative to the longitudinal axial direction of the tool. In this manner, the tool can allow crimping of connectors at a variety of different angles, reduce jaw length and width, and improve the leverage of the crimpers.

A clamp structure that provides versatility and structural adaptability to different clamping surfaces. A tension member can be coupled to the inside of a tubular body at one end and to a rod at the other end. Removable grips can be coupled to the ends of the body, but are not directly coupled to the tension member so that changing the grips can be done without removing the tension member from its anchored position. The grips can, in some embodiments, be pivotable so as to accommodate a variety of different gripping surfaces. Various holding members such as a tool holder, a utility hook and/or a claw grip can be movably provided on the body and can hold tools or light fixtures in a variety of configurations.

An automatic transmission fluid tester determines the remaining service life of automatic transmission fluid. The tester includes a radiation source for emitting radiation in the direction of an automatic transmission fluid sample under test, and a radiation receiver for detecting radiation passed through the sample. Based on the output of the radiation receiver, the tester measures the opacity of the sample. The remaining service life of the automatic transmission fluid is determined as a function of the measured opacity.

A circuit test light includes a reel-shaped housing formed of a light-transmitting material, with a light source disposed in the hub of the reel and connected to the proximal ends of two elongated test leads, the distal ends of which are respectively connected to connector assemblies. At least one of the connector assemblies includes a base connector and a plurality of adapter connectors selectively connectable to the base connector for use with different types of test terminals. The leads can be wound around the hub of the reel for storage when not in use, being retained in place by a suitable strap.

A wheeled, manually propelled vehicle with vertical support structure has an ergonomic handle attached to the support structure, the handle having a central section extending substantially horizontally in use and inclined sections which incline downwardly from the opposite ends of the central section and respectively terminate in curved end sections which curve toward the support structure and are integral for attachment plates for attachment to the support structure. The inclined sections facilitate grasping of the handle with an ergonomic arm position when a user is pushing the vehicle and facilitate maneuvering the vehicle around corners.

A breakout lead includes a length of insulated conductor having a bare uninsulated portion, and an insulating tubular sleeve coaxially and frictionally fitted around said insulated conductor and slidably movable therealong for covering and uncovering the bare insulated portion. Male and female terminals are respectively connected to the ends of the conductor length and are preferably covered by insulating boots.

A linearly moving external part of a multi-cylinder internal combustion engine is contacted with a hand-held contact tachometer for producing a waveform signal which, along with a signal responsive to the ignition of each cylinder, are applied to an engine analyzer processor for display of a single engine cycle of the waveform signal on the CRT oscilloscope of the engine analyzer. The variations and amplitude of the waveform signal correspond to speed variations of the moving part over an engine cycle to give an indication of the relative power contributions of the individual cylinders. Cylinder ignition markers and cylinder zone markers are respectively displayed at the top and bottom of the screen, respectively corresponding to the cylinders in their ignition order. Each cylinder zone marker is delayed a predetermined time from its corresponding cylinder ignition marker and indicates the time period during which the engine responds to the ignition event of the corresponding cylinder.

The pressure-testing apparatus comprises a manifold having a pair of conduits extending therefrom and being substantially parallel. Quick connectors at the free ends of the conduits have receptacles the axes of which are substantially parallel. A pair of adapters are respectively attached to the fittings of a broken coupler in a vehicle. The quick connectors are respectively applied to the adapter elements. The apparatus also comprises a pressure gauge on the manifold and/or means on the manifold for connection to a gauge.

Vehicular pressure-testing apparatus

A linearly moving external part on a multi-cylinder internal combustion engine is contacted with a hand-held rotary encoder, contact tachometer having a hollow handle in which processing circuitry is disposed for converting the rotary encoder output to a waveform signal. This signal, along with a signal responsive to the firing of the number one cylinder, are applied to an engine analyzer processor for display of a single engine cycle of the waveform signal on the CRT oscilloscope of the engine analyzer. The variations in amplitude of the waveform signal correspond to speed variations of the moving part over an engine cycle to give an indication of the relative power contributions of the individual cylinders.
