  • Patent number: 5521963
    Abstract: A mobile call processing methodology and concomitant system based on ISDN/CACH-EKTS technology which can broadcast incoming calls to base stations (e.g., 1050) and which uses the ISDN/CACH-EKTS bridging technology to handle base station handoff of an established call. Each mobile user (e.g., 1041, 1042) is assigned a unique EKTS directory number as well as a unique call appearance identifier, which allows for the handling of multiple call appearances of the unique DN on a single base station. For a given mobile communication application, the central office (e.g., 1014) treats the base station as an ISDN/CACH-EKTS terminal.

  • Patent number: 4840607
    Abstract: A weight reduced pulley for "K" type poly-v belt systems includes a body having an outer cylindrical surface. A plurality of raised ribs extend from said surface and run circumferentially around said surface. A plurality of trough areas are positioned between the ribs. The ribs and troughs corresponding to the location of indented and raised areas, respectively, on a poly-v belt. The ribs have a cross sectional profile extending radially traverse of the axis of rotation of the pulley, each rib being bounded by a pair of planar side walls at relative angles of The side walls terminate in a arc having a radius of 0.5 mm, the outermost point of said arc terminating 0.96 mm inward of the intersection of the upward projections of the planar side walls or apex. The planar side walls extend radially inward at least 3.44 mm from said apex. The trough areas are bounded by the outer cylindrical surface of said pulley, said surface being 3.57 mm from said apex.

  • Patent number: 4551122
    Abstract: A sheet steel poly-V-grooved pulley having a special cross-sectional contour is made optionally by any one of three different cold working manufacturing procedures. Special physical properties or characteristics are developed in the pulley by the manner in which the metal in the V-groove body and single and double walled terminal flanges are cold worked. The cold working involves forming in stages of manufacturing from a cup-shaped blank to the finished pulley product a stepped inner body wall surface equivalent to a tapered surface with improved substantially uniform torque transmitting strength in the grooved body from web wall to open end. Also involved in the cold working is an increase in pulley diameter in certain portions of the finished pulley and a decrease in diameter in other portions from the diameter of the side wall of the cup shaped starting blank.

  • Patent number: 4472162
    Abstract: A tensioning device for maintaining a predetermined amount of tensioning force on an endless drive belt for a vehicle accessories drive system. A shaft is mounted in a fixed position on the vehicle engine adjacent the drive belt. A housing is pivotally mounted on the shaft and is biased by a torsional coil spring in a belt tensioning direction. The spring is located within an annular space formed by spaced inner and outer housing walls and is telescopically mounted with respect to the shaft. A lever extends generally radially outwardly from the housing and an idler pulley is mounted on an end of the lever and is moved into tensioning engagement with the drive belt by the torsion spring. One end of the spring is attached to the housing and the other end is adapted to be fixed with respect to the shaft. The spring is placed in torsion and biases the lever and housing in the belt tensioning direction.
