A broken bulb remover with no moving parts comprising a rod serving as a handle with a central chamber open from the end of the rod to enclose the stem of a broken bulb. A lateral slot bifurcates part of the chamber for receiving the paddle-shaped part of the stem, which is used to unscrew the broken bulb. A tapered surface on the end of the rod contacts the inside wall of the broken glass envelope and stabilizes and centers the rod while it is rotated.

Broken bulb remover for removing a broken light bulb by twisting the glass stem protruding from the remnants of the broken bulb. A pair of longitudinal members of non-conductive material with handles on one end and semi-cylindrical engagement sections on the other end is connected together for pivoting about a fulcrum pin and socket. The engagement sections have silicone tabs for centering and stabilizing the tool when the handle sections are squeezed. Internal radial ribs on the engagement sect...

A broken trim die tool detection sensor. The lands of the tie bar die connect with the leads of the unit to form switches. The states of these switches indicate broken die lands or other malfunctions.

Broken conduit is repaired by enlarging the inner diameter at the broken end portion to provide a socket for receiving a coupling that has a male end portion with a reduced radial wall thickness and is configured so that the external diameter of the male end portion is closely received in the socket while the inner diameter thereof corresponds to the original inner diameter of the conduit.

A reaming tool for reaming a socket in a broken end portion of a cylindrical conduit enlarges the internal diameter of the broken end portion to provide a socket for receiving a male end portion on a repair coupling. The reaming tool is guided by the inner diameter of the conduit while reaming out the broken end portion to a socket diameter that is about midway between the original internal and outer diameters of the conduit.

A break in a rail, where two rails (12, 13) extend parallel to each other along a railway line, is detected by connecting the two rails together electrically with two electrical connections (16, 18) at opposite ends of a section of the line, causing electrical currents to flow in parallel along the two rails from a current source (22), and detecting (24) the currents flowing in each of the rails (12, 13). From the two values of current one can find it there is a break in one of the rails (12, 13...

A release mechanism adapted for coupling parachute canopy riser straps to parachute harnesses is described wherein the male and female members of the mechanism are held together by two axially aligned bolt elements (a broken bolt) disposed in a common coupling passageway defined through the male and female members. An integral electronic water-activated energizing mechanism drives the two element broken-bolt longitudinally in the coupling passageway allowing the male and female members of the me...

A tool for removing a tubular member having a threaded exterior, such as a pipe fitting, from a threaded bore. The tool includes a pilot section for guiding the tool into an interior of the tubular member, a shank section adapted for connection to a drill chuck, and a central body for engaging the tubular member. The central body has a cross section transverse the longitudinal axis that is generally circular and that tapers in diameter from the shank section toward the pilot section along an ent...

A system for detecting the presence of a broken tool in a manufacturing line uses a robot device separately positioned along the line. The robot unit has a plurality of probes which are inserted into openings in the item to detect the presence of a broken tool. The robot mounted detector replaces broken tool detectors mounted on index arms that support a plurality of gangheads that perform the machining operations on the item, allowing increased flexibility in the allocation and positioning the ...

An extractor for removing inaccessible broken key portions from keyways of tumbler locks wherein the extractor tool consists of a pair of thin elongated elements capable of being inserted into the lock on opposite sides of the broken key end portion and wherein twisting of the elements grips the broken key end to permit extraction from the lock. Extraction is aided by a pliers-like spreader tool having thin jaws inserted into the lock keyway for retracting lock tumblers, the dust shutter door an...
