Abstract: A temperature sensing system including a head unit comprising a thermal sensor for acquiring thermal data from a surface, a wireless transmitter wirelessly transmitting the thermal data, and a mounting interface; and a non-conductive pole connected to the mounting interface of the head unit.

Abstract: A multi-section telescoping pole for manipulating a tool. Sections of the pole have apertures. A pinch safety locking assembly includes a button configured for movement by a digit on a user's hand to a first position by a first resilient member when received in aligned first and second apertures to restrain the second section from moving relative to the first section and to a second position against a resistance provided by the first resilient member and against an elastic stop to permit relative longitudinal movement between the first and second sections. The pinch safety locking assembly is additionally configured to facilitate assembly by movement of the button by use of an excessive force to a third position against a combined resistance of the first resilient member and the elastic stop to permit relative movement between the pinch safety locking assembly and the second section.

Abstract: A line guard is configured so as to have a very large air gap with a small overall physical size of the device. Opposed interleaved sets of plural insulating leaves are formed along a discontinuity extending along the length of the line guard so as to greatly extend the length of the air gap. This air gap structure allows the overall size of the line guard to be small thus providing advantages of reduced weight, ease of handling, and ease of storage. A two piece coupler apparatus is provided for joining adjacent line guards in a way that is both flexible and provides sufficient dielectric to operate at high voltages in a small package.

Abstract: A cable cutting tool includes a first arm having a first jaw member connected to a first handle member and a second arm having a second jaw member pivotally connected to a second handle member. The first and second arms are connected by a fastener and are pivotal with respect to one another about a longitudinal axis of the fastener. A tension element is mounted on the second jaw member and is positioned wholly outside of and out of contact with the second handle member. A take-up element is mounted for rotation on the second jaw member. A latching mechanism is mounted on the second jaw member and is configured to inhibit rotation of the take-up element in a first direction. The take-up element is uninhibited by the latching mechanism when rotating in a second direction. A chain extends over the take-up element and has a first end attached to the first arm and a second end attached to the tension element. The chain is positioned wholly outside of and out of contact with the second handle member.

Abstract: A cutout fuse tube assembly installation tool includes a body member having first and second ends. A longitudinal axis passes through the body member. A protrusion extends outward from the first end of the body member and includes a head end spaced apart from the body member. The second end of the body member includes a bracket that has first and second arms spaced apart by an opening. A bracket axis passes through the opening. The bracket, the bracket axis and the protrusion are configured such that the bracket axis passes between the head end of the protrusion and the body member. A movable gate device is mounted on one or both of the first and second arms. The gate device facilitates opening and closing of an access to the opening through the ends of the first and second arms.

Abstract: A telescopic hot stick or pole for manipulating a tool from a position a selected distance away from a workpiece wherein the hot stick includes a tubular first section having a female end and a predetermined non-circular cross-sectional shape. A second section has a male end slidably engaged within the first tubular section and a predetermined non-circular cross-sectional shape conforming in a close-fit relation to the shape of the first section to prevent significant relative rotation of the second section therein. A locking assembly maintains the second section in an extended position where locking is accomplished in response to a sliding of the second section to the extended position and may be disengaged to permit ready removal of the second section from the first section.

Abstract: A conductor cleaning brush has a handle which is a single integral plastic part, the handle including a grippable center section having at opposite ends a mounting section and a brush supporting section. The mounting section includes a portion of noncircular cross section which extends into and mates with an opening of noncircular cross section in a shotgun stick. Two brush parts each have a cylindrical bristle arrangement, and have a stem which is fixedly secured in the brush mounting section of the handle. The brush parts diverge with respect to each other in a direction away from the handle, the ends of the bristle arrangements nearest the handle having radially overlapping bristles and the opposite ends of the bristle arrangements being spaced.

Abstract: A regulator neutral detector comprises a pair of probes for engaging the source conductor and the load conductor, respectively, of an electrical utility voltage regulator and a digital voltmeter for indicating the difference between voltages applied to said probes.

Abstract: A digital, high-voltage meter device is comprised of two poles, each having a probe connected to high-voltage resistors. The resistors are connected to supply low-voltage inputs to a digital voltmeter. In a modification, one of the poles including its probe and high-voltage resistor, is replaced by a connector, such as an alligator clip, adapted to be releasably connected to system ground.

Abstract: A voltage detector/indicator unit includes a plurality of lights for indicating a voltage within one of a plurality of different voltage ranges by lighting the lights in a selected pattern.

Abstract: An apparatus for providing a guard against electrical shock near an insulator carrying an energized, exposed conductor. In particular, this apparatus is intended for providing protection from electrical shock by providing a slotted insulator cover having means for moveably coupling a line guard thereto, said coupling means comprising a slotted ball and socket arrangement connected to the insulator cover and having a line guard adapter secured to the moveable portion of the ball and socket arrangement. By varying the degree to which the socket covers the ball, the degree of movement of the line guard adapter is defined. By closely fitting the socket to the ball, the insulator cover can be secured to the insulator by disaligning the slotted portions of the ball and socket.

Abstract: A manually operable tool for use by electric utility linemen for cutting electric conductors. The tool comprises an elongated pole having a cutter mechanism mounted on one end thereof. A manually operable ratchet mechanism is mounted on the pole close to the other end thereof and is connected to the cutter mechanism by linkage so that the cutting action is effected by operation of the ratchet mechanism.

Abstract: A telescopic pole having an elongated tubular handle section, an elongated tubular tool section, and one or more intermediate tubular sections. Each of the tool and intermediate sections is slidably telescoped within the next lowermost section and is provided with a manually releasable locking device which coacts with the next lowermost section for holding the sections in a fully extended position. The locking device includes a cylindrical locking member which is sealingly connected to the tubular section on which it is mounted. The locking device is provided with a small bleed hole which provides communication between the interior of the tubular section and the surrounding atmosphere for limiting the escape of air from one tubular section when the adjacent tubular section is being telescopically collapsed therein.
