摘要： A clamp-type ammeter probe includes two opposed jaws interconnected for pivotal movement between open and closed conditions and biased to the closed condition, with each of the jaws being of unitary one-piece molded construction. Each jaw includes a magnetic core unit comprising a core segment molded to a spacer segment and fitted within a channel-shaped shield segment to form a unit which is then molded between an outer shell and an inner segment of the jaw for encompassing the core unit except for exposed end portions thereof. These exposed portions on one jaw mate with those on the other jaw when the jaws are closed so that the core segments form a magnetic loop to encircle an associated conductor while the shield segments form a shield path encompassing the core loop. Stop surfaces on the inner segments provide a gap in the core loop in which a magnetic sensor is disposed. Guide surfaces control movement of the jaws to their closed condition to provide repeatable accurate alignment of the exposed portions of the core and shield segments to provide proper mating thereof.

摘要： A clip-like, resilient wire stub retainer and handle opening spring adapted for secure positioning on the pivoting joint area of a wire cutting pliers having a pair of cutting edges extends along a first cutting edge of the pliers in an overlapping manner so as to engage and retain a severed wire stub portion in contact with a second cutting edge of the pliers until the pliers are released in preventing the wire stub from being projected away from the pliers. The resilient clip-like retainer/spring biases the pliers to the open configuration and includes a sheath-like covering on the wire engaging portion thereof to enhance its wire retention characteristics.

摘要： An oscillator provides a series of pulses to the first of a plurality of cascaded counters. The BCD outputs of each counter provide a particular digit in the number of pulses counted during selected intervals. At least two AND means are coupled to respective sets of the counter outputs to provide speed signals when the corresponding numbers of pulses have been counted. A selected one of such signals resets the counters and also provides an inductive output for the magnetic probe of a timing meter. Additional AND means are respectively coupled to different sets of the counter outputs and provide timing signals when their respective numbers of pulses have been counted. A selected one of the timing signals energizes an LED which produces a light flash for the luminosity probe of the timing meter.

摘要： A chuck key holder for a power tool, such as an electric or pneumatic drill or the like, comprises an elastic member mounted on a part of the power tool such as the handle. The elastic member has an aperture therein adapted to receive a part of the chuck key, the aperture being of such size as securely to retain the chuck key frictionally, and to permit ready removable thereof for use, and easy replacement following use. The end of the aperture into which the chuck key part enters advantageously is defined by a chamfered surface which serves to facilitate entry of the inserted part. The holder is permanent in nature, enables the user to return the chuck key to a definite place following each use, thereby assuring that the key will be available conveniently for the next use.

摘要： An alternator produces current that has an average component and a ripple component. The alternator testing apparatus produces one voltage representative of the magnitude of the peak-to-peak amplitude of the ripple component and a second voltage representative of the sum of the average component and the peak-to-peak amplitude of the ripple component. A series of comparators each have their signal inputs coupled to receive the first voltage and their control inputs coupled to a divider network which is in turn coupled to receive the second voltage. Indicators are coupled to the comparators.

摘要： The circuit includes a phase-locked loop that produces pulses a fixed number of engine degrees before the ignition signals. These pulses are used to initiate the horizontal sweep of an oscilloscope that displays the ignition pulses. Accordingly, the ignition signals commence not at the beginning of the display where useful information may be lost, but rather a predetermined number of engine degrees later.
