Abstract: A socket retaining tool for preventing separation of a socket from a drive shaft of a driving tool. A keeper sleeve is configured to accommodate insertion and reciprocal movement of a quick change adapter and a quick change sleeve under the action of a biasing member. The quick change adapter has a male end and an opposite female end. The male and female ends are constructed and arranged to be used with locking mechanisms such that the socket is connected to the male end, and the drive shaft is connected to the female end. A socket locking mechanism coupled to the male end is enclosed by the keeper sleeve, and a driver locking mechanism coupled to the female end is enclosed by the quick change sleeve, when the socket retaining tool is in a relaxed position, thereby avoiding unwanted release of the locking mechanisms.

Abstract: A bolt heater including a junction housing, a handle attached and secured to a wall of the housing solely from an exterior of the housing, such as by a threaded connection, a power cable including a fitting attached directly to the wall of the housing, and an electrical resistance heater rod attached to the wall of the housing. The wall may have a boss with a recess therein for receiving a portion of the handle. The housing may be a hollow cylinder with a circular top wall, a circular bottom wall, and a cylindrical side wall. The heater rod may be attached to the housing via a threaded connection and the housing may have a non-circular portion near the threaded connection point, the non-circular portion being engageable by a tool to assist in the threading attachment of the heater rod to the housing.

Abstract: A body of water is aerated by propelling in the body of water a water pumping arrangement including a sheath having a turning propeller that (a) sucks water from the body into the sheath interior via openings in the sheath, (b) forces the sucked water upwardly and (c) forces the upwardly forced water through another opening in the sheath below the surface of the body of the water. Water forced through the another opening (i) has speed greater than the speed of the water sucked into the sheath and (ii) causes air bubbles to be induced in the water above the another opening.

Abstract: A resistance heating system is provided which includes a resistance heater, a source of alternating current electricity connected by conductors to the resistance heater, and a controller comprising a timer arranged to connect the source of alternating current electricity to the resistance heater for a selected time period and to disconnect the source from the resistance following the selected time period. In an embodiment, the resistance heating system is provided with a controller configured to be connected to a source of alternating current electricity and having a plurality of cable plug receptacles arranged to receive electricity. An electricity conducting cable having a cable plug at one end is configured to be received in the receptacles and has a resistance heater provided at an opposite end. A master timer may be connected with a communication arrangement to the controller. The master timer is arranged to control an electric output of a plurality of the receptacles.

Abstract: An induction heating device having a pair of inductors in a sub-assembly connected by fluid conduits to a cooling apparatus and by electrical conductors to an inverter and impedance adjusting circuit has a quick disconnect terminal assembly arranged closely adjacent to the inductors. This permits the inductor sub-assembly to be quickly and easily disconnected from the conduits and conductors so that the inductor sub-assembly may be moved to a new location easily and quickly. A plurality of inductor subassemblies may be used with a single terminal assembly to provide an accelerated method of heating a series of items by successively moving the terminal assembly to a next inductor sub-assembly to begin heating and to then move the non-disconnected inductor assembly to a new location while the next inductor sub-assembly is operating.

Abstract: An electronic taper gauge system provides an elongate taper gauge member having a free end for insertion into a gap to be measured and a movable stop member for defining an insertion distance of the elongate member into the gap. Arranged between the movable stop member and the elongate member is a position sensor which emits a position signal to a conversion device which converts the position signal into a lateral dimension signal of the taper gauge. The conversion device transmits the lateral dimension signal to a data storage device for recording the gap dimension.

Abstract: The present invention provides a method and quick-disconnect apparatus for disconnecting power to a three-phase motor. The present invention provides a quick-disconnect apparatus for efficiently and easily disconnecting three-phase power to a motor having a receptacle terminal box with a first plurality of quick-disconnect receptacles, a second plurality, half of the first plurality in number, of bus bars connecting pairs of the quick-disconnect receptacles, and the second plurality of power cables individually connected to the bus bars for providing current to the three-phase motor.

Abstract: A hole tapping device having a motor driven tapping tool with a bracing frame for resisting reverse torque on the motor frame caused by resistance of the rotation of the tapping tool within a bore being tapped. The bracing frame has adjustable arms which provide adjustment in the radial and angular direction and which clamp stationary protrusions on the workpiece with rollers to hold the bracing frame against rotation in both directions about the axis of the bore. The adjustments of the frame provide great geometric versatility. The rollers provide for a smooth translation of the motor and bracing frame along the axis of the bore being tapped. A single coupler and a series of inserts allow for a series of differently sized tap tools to be driven through the use of a single coupler.

Abstract: A thread cutting tool which can be configured to cut threads in a variety of bore sizes using universal thread cutting chasers mounted in select radial extension such as by using variable length tool blocks which are themselves interfit within retaining slots in the head portion of the tool, or by providing alternate radial position notches an the head portion for mounting the cutting chasers. By using variable tool blocks mounted to the head portion of the tool, universal thread cutting chasers having a preselected thread pitch can be utilized for multiple bore sizes, thus saving the expense of providing chasers or head portions corresponding to each bore size. Alternately, by providing alternate radial position notches in the head portion for mounting the cutting chasers, a single tool can be used for different bore sizes, such as for undertaking a start thread cut in a bore and then undertaking a finish thread cut in the pre-cut bore using an alternate radial position for the chasers.
