Abstract: An Adjustable Canopy, for use in combination with a picnic table or the like, to protect the users from the elements and which is quickly and easily removable in anticipation of severe conditions. Furthermore, a new design of Picnic Table, for use with the Adjustable Canopy, which has no significant obstructions to entry or exit and which can be Pivotable, thereby allowing an unlimited range of adjustments to impede the elements, regardless of the originating direction.

Abstract: A Pre-stamped Half-hinge Adherent Cover designed to thoroughly protect all exposed surfaces of a half-hinge attached within the hinge recess of a door or jamb during the operation of coating and which combines the advantages of rigid covers (easy and quick to align and apply) with the advantages of flexible adhesive covers (securely remains in place and less expensive). In the preferred embodiment, numerous Pre-stamped Half-hinge Adherent Covers are provided on a roll so a painter can quickly and easily peel one off the roll and apply it to a half-hinge, greatly reducing the time involved in preparing a door or jamb to be coated and replacing the door in its jamb.

Abstract: An apparatus (10) to convert a four-stroke internal combustion engine to a two-stroke pneumatically powered engine. An air compressor (60) is driven using the rotation of the crankshaft (22) and compressed air is delivered through a supply line (74) to at least one holding tank (68). A supply line (76) delivers compressed air from the tank (68) through a regulator (20), which controls the pressure and volume, to the pneumatic distributor (24). A plurality of high pressure hoses (50) finally communicates the compressed air to the cylinders (86) of the engine (12) via the spark plug orifices (18). The pneumatic distributor (24) has a rotor (42) which opens gate valves (44) to supply compressed air to the cylinders (86) wherein the pistons (88) are at top dead center, making every downstroke a power stroke. The modified dual-lobed camshaft (80) operates the exhaust valves (84) so that every upstroke of a piston (88) is an exhaust stroke and exhaust freely escapes through the exhaust manifold (90).

Abstract: An improved door and jamb mortising pilot having the capability of performing numerous mortising operations effortlessly; having hinges to enable folding to a compact unit; having slide locks to prevent unintentional folding; having fixed guide pins to affect perfect alignment on a door or jamb; having a non-adjusting permanent rotating door and jamb margin spacer; having two alternative means of attachment to a door or jamb, specifically, anchor pins and gripping devices; having mortising guide templates that are interchangable to accommodate popular size hinges; and having mortising guide template pin locks to ensure position of mortising guide templates; said folding door and jam mortising pilot being highly adaptable but completely eliminating measurements and adjustments.
