Abstract: A crimping tool is provided for attaching a connector to a shielded coaxial cable. One connector on which the tool can be employed is an improved BNC type connector including a sliding center pin which is movable into the interior of the connector, such connector also including a crimpable ferrule for holding the cable to the connector. The crimping tool includes a pair of opposed crimping dies for crimping the ferrule to hold the connector to the cable. A lower crimping die of the tool includes a fitted receptacle for receiving the connector. A pair of handles are coupled to the opposed crimping dies to drive the dies together to crimp the ferrule. The crimping tool further includes a driving member for pushing the center pin of the connector into the interior of the connector simultaneously with the closure of the crimping dies to crimp the ferrule onto the shielded cable.

Abstract: A fiber optic cable lateral illumination system comprising a housing having an internal cavity and an aperture communicating the cavity externally of the housing, an optical system located within the internal cavity; the optical system comprising a reflector and a high intensity lamp positioned within the reflector for directing light along an optical axis, a plate of heat absorbing material spaced from the reflector, and at least one color filter spaced from the plate and the reflector; the optical cable including a plurality of optical fibers and a ferrule assembly for supporting the cable to the optical system.

Abstract: A golf ball having a reduced spin rate is provided for minimizing the tendency of the golf ball to hook or slice in response to a sliding blow from a golf club. The golf ball may have a cover that is constructed to have a slippery surface such that when the club strikes the ball the club slides on the surface rather than imparting spin to the ball. In addition, the cover may be isolated from the inner core of the golf ball by an intervening lubricating layer which allows the cover to slip on the core so that any spin imparted to the cover is only minimally transferred to the core thereby minimizing spin of the golf ball. The golf ball may also be constructed with a fluid core either of a liquid or gelatinous substance which will not respond to any initial spin imparted to the outer cover of the golf ball and will thereby retard the spin rate of the ball.

Abstract: An electrically powered pumping system for extracting liquid from a deep container includes an electric motor having a rotor with a drive shaft connected thereto. A centrifugal pump has a driven shaft, and a shaft extension is coupled at one end to the drive shaft of the electric motor and at an opposite end to the driven shaft of the pump. An elongate support member has a first end for receiving the electric motor and a second end for connection to the centrifugal pump. The support member has a central passageway extending from the first and second ends for passage therethrough of the shaft extensions, and a plurality of spaced bearing members are provided in the support member for rotatably supporting the shaft extension therein.

Abstract: A roller screw assembly includes a threaded rod, a nut having internal, non-helical grooves and a plurality of externally grooved elongated rollers seated circumferentially about the rod and captured in place by the nut. The grooves in the nut and rollers are selected to have the same spacing as the pitch of the rod threads and with a corresponding profile so as to allow intermeshing engagement between the nut, rollers and rod. The inner surface of the nut is formed such that a cross-section normal to the axis of the rod illustrates at least one lobed area which is of sufficient extent to allow a roller in that area to translate axially with respect to the rod. The number of lobes is dependent on the number of threads or parallel helices formed on the rod. Rotation of the nut with respect to the rod enables axial translation of the nut with respect to the rod by recirculation of the grooved rollers at the lobed region.

Abstract: A wide-angle viewing attachment for an ocular microscope includes a first lens attached to the microscope and a second lens independently mountable with respect to the microscope. The second lens is positionable proximal to an eye of a surgical patient and is maintained in the proximal position by an attachment system including a support member coupled in a fixed position to an operating table on which the patient is reclined. A first support rod extends vertically from the support member and a clamp member is adjustably mounted on the support rod. A horizontally extending second support rod is adjustably coupled to the clamp member and terminates at one end in a generally flat plate. A lens carrier includes a spring clamp for holding the second lens and a support arm extending generally horizontally with respect to the first support rod. The carrier terminates in a magnet assembly which holds the lens carrier to the flat plate.
