Abstract: Modular plastic structural composites having a web section disposed along a horizontal axis and at least one flange section disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of the web section, wherein said composite is formed from a mixture of (A) high density polyolefin and (B) a thermoplastic-coated fiber material, poly-styrene, or a combination thereof. Composites molded in the form of I-Beams and bridges constructed therefrom are also disclosed.

Abstract: A portable pulling tool is provided including an integrally formed one-piece gear case for positioning all of the gear train components. The gear train includes a combination of helical gears and a differential planetary gear unit in a unique configuration. A motor control system is provided to automatically shut off the motor when a predetermined current load is detected. A multi-segment LED is provided to indicate to the user the amount of load that is being applied.

Abstract: A tool for pulling a wire (W) through a connector (C) or a terminal has a pair of levers (20, 24) pivoted together, one lever (20) having an abutment portion (23) for location of the connector (C) and the other lever (24) having clamping members (26, 28) for gripping the wire (W), characterised in that one lever (24) has a handgrip portion (25) articulated to a shank portion (40) for movement between an in-line position and a position inclined towards the handgrip portion (22) of the other lever (20), spring-loaded latching means (45) being provided between the handgrip portion (25) and the shank portion (40) for disengagement when the tension in the wire (W) reaches a value set by a knob (72) for loading the spring means and indicated by a pointer (73) against a scale (74).

Abstract: A rachet strap tightener and a power driven rotary tool are arranged to be operated together for tightening a strap. The body of the power driven rotary tool is arranged to be anchored in mating engagement relative to the body of the rachet strap tightener, in addition to coupling the rotating mating parts of the tool and the strap tightener, such that the torque applied when winding the spindle of the tightener no longer acts to twist the tightener body from the user's hands but rather the torque is anchored directly through the bodies so that winding of the spindle with the power driven tool can be accomplished quickly, efficiently and in a safe manner.

Abstract: A lifter is disclosed using two transmission mechanisms at two sides of a housing for lifting, for example, a bed or chair, each transmission mechanism including a motor. a worm gear wheel meshed with a worm shaft as the output of the motor, a screw rod threaded into an inner thread in the hollow gear shaft of the worm gear wheel, a push block fixedly fastened to one end of the screw rod and moved with the screw rod to lift/lower the load upon rotation of the motor, and a sliding block fixedly fastened to the other end of the screw rod to guide axial displacement of the screw rod in the housing.

Abstract: Apparatus for mounting a banner from a support member at a display height above ground level includes upper and lower banner mounting arms that are capable of receiving and mounting a banner with the assistance of an operator located at ground level.

Abstract: A load binder tool uses a pair of first and second coupler-tension members pivotal connected, at spaced apart centers, to an operating handle. A pair of major gear members engage a pair of minor gear members attached to the first coupler-tension member. A tension connector pin is journaled to both the major gear member and one end of the second coupler-tension member. The rotation of the connector pin about the axis of rotation of the major gear members creates an additional mechanical advantage. This rotation about the axis of rotation of the major gear members also causes the connector pin axis of rotation to be offset relative to the major gear axis of rotation in order to lock the load binder tool in the closed position using the tension applied to the load binding tension members or chains.
