Abstract: Four different combinations of a sliding internal shutter and shutter lock control mechanism are described along with methods of incorporating the combinations into receptacles to prevent foreign objects from gaining access to power. Each combination is composed of a ramped shutter, spring biased in a closed position, and two to four lock control mechanisms, each of which moves a locking bar out of contact with an impeding surface on the shutter. The entrance of a standard plug into the assembled receptacle moves all the locking bars away from the shutter's impeding surfaces and the blades interaction with the ramps moves the shutter to the open position allowing the blades to continue to power. The combinations may be installed in receptacles as standalone modules that are installed in a receptacle case or the parts may be integrated directly into a receptacle structure with the proper support structure.

Abstract: A lawn tarpaulin of strong, flexible material for collecting and hauling leaves and lawn debris is described consisting of a rectangular tarpaulin with two or more weighted and partially stiffened edges. Both the weight and stiffening are provided by a plurality of strips of stiff dense material, such as metal strips, fastened to the tarp edges alternating with short gaps of flexible tarpaulin edge between them. This allows the tarpaulin to be folded for convenient storage. The weighted edges keep the tarpaulin from bowing in the wind and stable when raking debris onto the tarpaulin. A handle attached to one corner of the tarpaulin connects the opposite corner and to at least one central point on a front edge for hauling. The partially stiffened edges cause the tarpaulin to assume a shape while hauling that encloses the load and prevents spillage.

Abstract: A method of mounting a detachable drawlock to a compound bow is disclosed. It consists of a fixture attached to the bow and a drawlock having complimentary mounting means that fit in the fixture securely but detatchably. A detatchable drawlock is disclosed wherein the bow mounted fixture is a quiver mounting block that attaches at the bow sight. The detatchable drawlock comprises a mounting plate bearing the same mounting means as the quiver which detatchably mounts in the quiver mounting block, a rod attached to the mounting plate to hold the draw, and a mechanical release at the distal end. The mechanical release disclosed comprises a string catch that is spring biased to the cocked position, a trigger, and a safety that is spring biased to the on position. The drawlock carries on the quiver for transportation and storage.

Abstract: An Archery Bow Steady Rest and Holder for hunting which holds a bow in a ready vertical position in front of the archer with arrow nocked while waiting for game, and which also supports and steadies the bow and user's arm while drawing, aiming and firing. It comprises a swiveling support boom attached at its proximal end to a vertical surface, with vertical support elements attached near the distal end of the boom, and a bow attaching device holding the bow at the riser between the hand grip and upper limb. The bow may be freed from the support system simply by lifting it.
