Abstract: The present invention is a hands free dive flag connector comprising a retractable lanyard dispenser releasably attached to dive gear on a scuba diver. Complementary hook and loop materials are attached to the dive gear and the retractable lanyard dispenser to form a releasable connection between the diver and the hands free dive flag connector. A lanyard is retractably wound on a spool in the retractable lanyard dispenser and attached to the spool at a dispenser end. A spring in the retractable lanyard dispenser maintains tension on the lanyard between the diver and the dive flag attached to the lanyard. A lanyard connecter is attached to the second end of the lanyard adjacent to an extended lanyard portion extending from the lanyard dispenser. The lanyard connecter attaches to the dive flag.

Abstract: An aerodynamic, lightweight, flexible material top for enclosing a flatbed of a wheeled vehicle having a front and rear, the top includes a series of inverted, U-shaped supports extending upwardly from and across the flatbed with a first support at the front and a last support at the rear. A flexible material is stretched over the supports and includes a fixed sleeve and a laterally adjustable sleeve which are secured about the first and last supports. At least a portion of the top is pivotally connected as to swing upwardly away from the flatbed to gain access under the top and to the flatbed.

Abstract: A protective batting glove having finger portions for covering the fingers and hand of an individual, the glove includes a cushioned shield engaged to the glove proximate to the back of the hand of the individual such that the shield is concealed to provide the appearance of a conventional unprotected batting glove.

Abstract: A permanently sealed, lighted, inflatable device comprises a permanently sealed outer shell, an inner inflatable bladder disposed within the outer shell, a valve for inflating the inner inflatable bladder, and a self-contained, non-replaceable illumination element disposed between and engagingly held in place by the inner inflatable translucent bladder and the outer translucent shell. The illumination element includes a control element for conserving battery life. The bladder and shell have translucent portions through which light from the illumination element passes.

Abstract: The present invention applies the leading edge of a closure tab to the top surface of an article traveling through the apparatus at a constant speed and positioned at precise intervals by lugs on a conveyor belt, bends the closure tab around the trailing surface using a blast of air, engages and accelerates the closure tab forwardly with respect to the article to press the closure tab on the bottom surface of the article with an inclined bottom belt located underneath the article and traveling at a greater rate of speed then the article itself, squeezes the article with two nonparallel belts located laterally at the position of contact with the closure tab to press the closure tab to the top and bottom surfaces of the article for closure.

Abstract: Disclosed is a three piece snowmobile dolly system that during use is secure in placement under a snowmobile and during nonuse may be compactly nested together. The dolly system is comprised of two forward ski dollies and a rearward track dolly. Each of the forward dollies have a planar base portion with two sidewalls for receiving one of the skis and a V-shaped depression in the planar base for receiving and engaging the wear bar on the bottom of the ski. The rearward dolly has a planar base with four castors for stability. The planar base portions with the sidewalls of the forward ski dollies mesh together and the rearward dolly nests intermediate the castors of either forward ski dolly resulting in a compact package for storage.

Abstract: Disclosed is a passive, highly efficient, low noise coupling device that includes a balun and noise reduction circuitry uniquely configured for converting an unbalanced video signal on a 75 ohm transmission line or connector to a balanced signal on a 100 ohm transmission line or connector and vice versa. The device efficiently allows use of a 100 ohm unshielded twisted pair, such as a conventional telephone cable, for multiplex transmission of video signals or the like in the frequency range of 50 to 500 megahertz. The preferred embodiment has a circuit board with a 75 ohm unbalanced side and a 100 ohm balanced side separated by a balun having a toroid core with a very high permeability. A common mode choke for noise rejection is inserted in the balanced side. The choke has a dual toroid core, one core of high permeability and one of low permeability, and has windings with a 100 ohm characteristic impedance. A common mode toroid shunt on the device's balanced side provides further noise reduction.
