Abstract: A portable, user configurable service stand for a variety of riding lawnmowers and other motorized implements. The stand comprises a rigid frame with an elongated, longitudinal section spanning between twin, spaced apart vertical frame sections that support the load. Each vertical frame section secures generally planar, horizontal wheel supports. A pair of parallel, removable spans is coupled between front and rear wheel supports to temporarily provide a travel pathway over the stand. Removable, drive-on ramps are pivotally connected to the frame. After a mower is parked on the stand, the spans may be slidably removed, exposing the sides and undercarriage of the mower for convenient access. Upon removal of the spans, a pair of gravity-operated safeties automatically deploys to block the mower front wheels.

Abstract: A portable, self-contained race car cooler comprises an enclosure divided interiorly by vented baffles into separate cooling and fan compartments. A removable top covers the enclosure. Air is drawn through the enclosure and between adjacent cooling compartments by an electric fan. A plurality of removable canisters, frictionally fitted through orifices in the top, store “dry ice” for cooling. Each canister is peripherally restrained by a plurality of radially spaced-apart J-hooks emanating from the top that are biased inwardly by an elastic band. The J-hooks peripherally grasp the canisters and provide a detent for snappingly engaging or releasing the canisters. A heat-exchange standoff is secured beneath each canister upon the enclosure floor and comprises a plurality of spaced-apart, parallel rails with air passageways defined between them. Cooler lids removably coupled to the canisters are externally serviceable. Carbon dioxide venting is provided.

Abstract: A hand-controlled, curb forming machine that is transformable between different widths and geometries, and between different wheel configurations, to accommodate different concrete curbing. A downwardly projecting, rotating head that rotates about an axis perpendicular to the slab shapes raw concrete into appropriately styled and contoured curbs. A machine frame slidably receives an adjustable, wheeled subframe. A roller on the opposite frame side rides on an opposite curb form. A pivoted handle is reversible. The electric motor is adjustably secured to the frame by a mounting plate movable within follower slots in the frame. A removable adaptor plate disposed on an opposite frame end supports the machine when not in use, but can be removed for normal curb work exposing a form riding roller. When the machine is deployed with monolithic curbs without rebar, the adaptor plate can mount to the subframe to raise the machine by lowering the wheels.

Abstract: An internal combustion engine uses separate, tubular and hollow reciprocating sleeve valves that open and close intake and exhaust passageways for improved aspiration. The sliding sleeve valves are disposed within sleeves horizontally disposed within a modified head secured above the combustion chamber. The valves are driven in a path normal to the engine pistons by an independent crankshaft that is rotated through an external pulley driven by the engine crankshaft. Fluid flow occurs through the valve interior and through ports dynamically positioned above the compression cylinder, proximate aligned sleeve and head ports. Sleeve ports are separated by bridges that maintain valve rings in compression during reciprocation to prevent damage. Each valve body has a reduced diameter midsection forming a relief annulus that distributes shearing pressures about the circumference of the valve.

Abstract: A bag tossing game for one or more by players comprises foldably deployable target assemblies, associated stabilizing assemblies linked to the target assemblies, and a plurality of bags for throwing by players. Each target assembly presents an inclined impact surface with a target aperture towards which bags are thrown. A foldable elevator pivoted to the target assembly angles the target assembly during play. Foldable feet at an opposite end of the target assemblies offer further support. A stabilizing assembly associated with each target assembly comprises a base disposed on the supporting surface, a platform mounted over the base for supporting bags and beverages and an elongated stanchion extending upwardly from a socket in the base for supporting the platform. The base comprises an elongated slot and cooperating guide channels for interconnecting each target assembly elevator with the stabilizing assembly.

Abstract: Vending machines, automated retail stores, and retail displays with computer controlled, item-based lighting that produces variable visual effects in conjunction with actual or potential vends to provide an enhanced vending experience. Offered products are stored within display tubes that are arranged in orderly geometric arrays. RGB lighting through a plurality of LED banks within polygonal circuit boards associate with each display tube are controlled by a computer activation system that senses the presence of a customer, and the selection of a vend. Combinations of differently colored LED's are computer controlled on a per product basis to artistically illuminate available products and assist customers. Pre-programmed lighting sequences can switch LED off and on, vary their intensity, and alter resultant colors. A touch screen computer responds to user inputs for selections and transactions.

Abstract: Contact tubes and coaxial cable fittings with the tubes, including barrel connectors, right angle connectors, and sockets. The elongated, tubular contact tube extends coaxially within each fitting, establishing at least one female juncture for receiving the center conductor projecting from a coaxial connector. The insulators and bushings center and retain the contact tube within the connectors. The contact tubes are rolled from beryllium, copper alloy sheets having slotted portions defined on one or both sheet ends. The slotted portions comprise a plurality of parallel, curved, slots, each of which borders curved metal strips. Half slots at the bottom and top of the slotted portions adjoin each other after rolling to form an additional slot. Because of the shape of the slots and strips a generally pentagonal configuration is assumed after rolling and contraction of the slotted region, such that contact points overlap.
