The rebuilding apparatus includes a substantially conventional boring machine having specially configured mounting components which facilitate securement of the apparatus to various axle structures.
Abstract: The disclosure provides an apparatus for extracting heat and/or mechanical energy from a pressured gas wherein the pressured gas is applied to the radially outer ends of rotating cylinder elements defining logitudinally extending fluid pressure chambers having one end thereof remote from the axis of rotation and the other end proximate to the axis of rotation. A free piston is mounted in each of the fluid pressure chambers and is reciprocable therein solely under the influence of the gas pressure and centrifugal force. Valving elements are provided at the outer end of the cylinder elements which are operable by the movement of the free piston toward such outer end to open the pressured gas inlet valve. A second valving element is provided near the inner end of each fluid pressure chamber to open ports causing the exhaust of the expanded, cooled gas from the chamber.

The bits or pieces of edible material are agitated or vibrated as the edible material is fed to the periphery of a body or column of soft confection. The body or column of soft confection and the bits or pieces of particulate edible material on the periphery of the body or column of soft confection are moved through a restriction to impress or embed the bits or pieces of particulate edible material in the periphery of the soft column of freezable confection.
Abstract: The disclosure relates to a pneumatic splint formed of three similarly shaped walls of flexible thermoplastic material. The inner and outer walls are of identical shape and are peripherally bonded to each other.

Abstract: The present invention relates to an instrument for measuring the range of angular displacement associated with two human body portions connected to a common joint. The instrument includes two pivotally connected, elongate rods, and separate supports for supporting each of the rods on a respective one of the body portions in spaced relationship with the body portion. Each of the supports includes a pair of ball and socket assemblies which are mounted on the respective body portions in spaced relation to one another. The ball of each ball and socket assembly has an aperture formed therethrough for receiving the associated elongate rod. Such a support arrangement enables the body portions to be rotated about the common joint without affecting the natural movements of the body portions. An encoder is utilized to pivotally connect the two elongate rods and to generate an electrical output signal representing the relative angular position between the two rods.
Abstract: The present invention relates to a vise for securely supporting a workpiece relative to a fixed support. The vise includes a base member which is secured relative to the fixed support. A clamp assembly is rotatably mounted with respect to the base member and includes a pair of jaw members one member of which, except for the relative rotative movement between the clamp assembly and the base member, is fixed relative to the base member. The second jaw member is pivotally interconnected to the first jaw member. Both jaw members have a workpiece engaging surface formed thereon with the engaging surfaces arranged in a facing relation to one another. The vise further includes a threaded handle pivotally mounted on the second jaw member and cooperating with the fixed jaw member for pivoting the jaws relative to one another to move the workpiece engaging surfaces toward one another whereby a workpiece positioned between the surfaces will be securely supported.
Abstract: A pneumatic brake assembly for incorporation into chain hoists and the like includes a planar disk slidably secured to the output shaft of a pneutmatic motor by complementary splines. The disk is biased toward a planar surface and when in contact with such surface, inhibits rotation of the motor output shaft. Compressed air is supplied to both the pneumatic motor and the brake assembly through a network of passageways and check valves. Compressed air supplied to one face of the brake disk, translates the disk, disengaging it from the planar surface and permitting output shaft rotation.
Abstract: An adjustable neck-body joint for a guitar-like instrument is disclosed. The instrument includes a main body portion and an elongated neck portion having at least two threaded apertures formed transversely therein near one end. The main body portion includes a recessed portion for receiving a mounting frame adapted to receive the one end of the neck portion. The frame includes respective apertures formed therein for generally aligning with the threaded apertures when the one end of the neck portion is received by the frame. Threaded fastener means extend through each of the frame apertures into cooperation with the threaded apertures for frictionally securing the neck portion to the frame. The threaded fasteners are smaller in diameter than the apertures formed in the frame such that, when the fasteners are loosened, the neck portion of the instrument can be adjusted relative to the frame. The frame is integrally secured to the main body portion of the instrument by a plurality of threaded fasteners.
Abstract: This invention relates to a retaining sleeve which is utilized in conjunction with an associated threaded cap to hold a replacement shock absorber within the cylindrical shroud of a vehicular suspension system of the type commonly referred to as a MacPherson strut suspension system.

The lower end of the upper member is provided with collet portion having a plurality of radially movable arms. The collet portion has external tapered formed thereon for engagement with internal tapered threads formed on the upper end of the lower member. The relative rotation between the upper and lower members in one direction causes the collet arms to move radially inwardly to securely grip the outer wall of the cylindrical shroud. After a replacement shock absorber is inserted within the cylindrical shroud, the threaded cap can be secured to the upper end of the retaining sleeve.
