A machine tool in which a plurality of machining positions is orbited by a work spindle unit carrying a workpiece and capable of radial displacement relative to the central axis of rotation. The work spindle unit may be one of one or more such units mounted upon a bridge element angularly displaceable about that axis.

A stretching apparatus for use on a golf course provides a wall with a top ridge, a reclined plane and a curb platform, each capable of supporting all or part of a human body. The top ridge may have at its opposite ends, multiple horizontal levels of differing heights. The wall has an obverse surface against which the reclined plane is disposed, and a reverse surface against which the curb platform is disposed. The stretching center may have stilts that elevate the reclined plane above the groun...

A network operations center comprised of hardware and software that tests paging devices, such as two-way paging devices to determine that they conform to a specified protocol.

A filter assembly includes a filter cap having a filter chamber defined therein. The filter cap includes a side wall having an opening defined therein. A fluid filter is positioned in the filter chamber. A spring-loaded detent button is movably secured to the filter cap and extends into the filter chamber. When the detent button is depressed by a user, the end of the detent button positioned in the filter chamber contacts the fluid filter thereby releasing the fluid filter from the filter cap. A...

A printer employs an ink ribbon in the form of a tape and is provided with a control system for judging proper printing positions of characters to be printed within respective printing ranges and for determining the relative position of the ink ribbon with respect to a printing head and a stepping motor for shifting the ink ribbon in a direction widthwise of the ink ribbon in response to signals from the control system so that printing is performed utilizing only the center portion of the ink ri...

An end plug for a coaxial cable in which the center conductor contact comprises an extension of the dielectric spacer of the plug with the center conductor of the cable being positioned around the spacer extension in grooves formed therein. The depth of the grooves is less than the center conductor diameter so that the center conductor extends out the grooves and will make electrical contact with a mating connector.

The present invention discloses an improved center pivot for a self-propelled center pivot irrigation system. The preferred embodiment is characterized by a vertical pivot pipe supported for rotational movement at both the upper and lower extremities thereof. Additionally, the gasket assembly providing leak-proof rotational movement of the pivot pipe relative to a fixed liquid supply pipe is characterized by a slideable casing which can be moved from a normal operating position wherein the fixed...

Helical spline actuator includes a pair of cylinder housings connected together in end-to-end spaced apart aligned relationship by means of a center mount. A shaft is mounted for rotation within the two housings, and has a rotatable drive member extending outwardly therefrom between the spaced apart inboard ends of the housings and out through a circumferential slot in the center mount. Pistons are axially movable within each of the housings toward and away from opposite ends of the shaft. Inboa...

This invention relates to a machining center fluid delivery system comprising a body block to be mounted on a tool holder to be installed in a machining center and a driving source block to be mounted on the machining center, and to a machining center equipped with such a fluid delivery system. The invention assures an exact orientation of nozzles and their delivery of a machining fluid towards the machining point which is constantly shifted with the progress of machining operation, thus contrib...

A center brace for a railway vehicle is provided with a detachable center plate having a boss disposed in a socket or recess in the center brace and a base of greater cross-section. The separable center plate may be of a more wear resistant material than that of the center brace.
