Abstract: A lighting system for projecting a beam of light has a light source and a concave reflector having a central axis. The center of the light source is located at a position other than at the focal point of the reflector, i.e. between the reflector surface and the focal point of the reflector for an ellipsoidal reflector and forward of the focal point for a parabolic reflector. This placement provides a greater light output than is achievable by positioning the light source at the focal point of the reflector. The preferred light source is an improved lamp having an incandescent filament having a central linear helical portion aligned with a central axis of the reflector and a peripheral helix portion around the central portion so as to concentrate the emission of light along and about the central axis of the filament.

Abstract: A ball type yarn tensioning device with improved threading capability is disclosed. The device includes a ball chamber having an open top. The ball chamber terminates downwardly in a bottom insert which provides a seat for a ball within the ball chamber for yarn tensioning. A cap overfits the top of the ball chamber and includes a diametrically positioned, elongated opening. A top ceramic insert of elongated rounded configuration is secured about the elongated top opening and the yarn passes therethrough. The elongated configuration facilitates threading the device by permitting a threading instrument to be inserted through the ceramic insert and the bottom insert in slanted orientation that is angularly offset from the longitudinal axis of the device.

Abstract: A yarn tension device is disclosed which includes a generally hollow, cylindrical body having an open top and an interior channel of sufficient size to contain one or more tensioning balls. The body terminates downwardly in inwardly converging bottom walls within which are mounted a pair of diametrically opposed ceramic eyelets for yarn inlet and yarn outlet. A flanged roller is horizontally positioned at the bottom of the body in transverse alignment to a plane through the eyelets to apply tension to yarn passing through the eyelets. The body is formed with parallel, planar walls adjacent to the roller flanges to maintain the position and orientation of the roller during yarn tensioning.

Abstract: A combination mounting bracket, ball tension and balloon control comprising a unitary mounting arm and balloon control disk for use on creels of warping, winding, beaming, weaving and other types of high speed textile machines. The device includes provision for either right hand or left hand mounting of a ball tension which functions in cooperation with the balloon control to feed the yarn to the machine.

Abstract: A ball tension device for horizontal yarn comprising generally a body defining a vertical channel within which one or more balls can be positioned to vary yarn tension. A pair of horizontally aligned openings communicate with the bottom of the channel to provide for yarn inlet and outlet as the yarn passes through the device. Similar, ceramic inserts line the inlet and outlet openings and are angularly downwardly inclined to define a pair of opposed, angularly inclined conduits through which the yarn horizontally passes in the tensioning procedure.
