Abstract: A two-wheeled lawn trimmer, controlled with a handle attached to a frame which receives a conventional gasoline or electric powered rotary lawn trimmer, and provides balanced maneuverability with low operator forces while providing complete trimming access and cutting height control. Additionally the trimmer provides the operator access to vary the rotary cutting head speed as well as the ability to stop the motor device with controls mounted on the handle grip assembly.

Abstract: A portable containment structure for abrasive blasting equipment is designed for particular application in the cleaning of large storage tanks and for bridges. The unit includes a portable blasting room which fully encloses the blasting apparatus and operating personnel, in a secure environment having ventilating and vacuum means for the safe removal and containment of particulate materials and contaminates. The unit is supported by cables and includes rigging which provides for both horizontal and vertical movement along the surface being treated.

Abstract: A board game simulating an automobile race for one or more players includes a flexible game board with a first race track depicted on one side and a second, generally smaller, track on the opposite side. A textured track surface on preferred embodiments enables playing cars to remain in place if the flexible game board is placed on uneven or banked support surfaces to simulate real-life tracks. A plurality of charts determine the course and type of movement along either track, responsive to the roll of one or more dice, each die being of a distinct color to indicate a specific chart. Novel rules for playing require decision making and strategy, thus creating a realistic environment of racing, changing with each play of the game.

Abstract: A fastening device for a canoe cover consists of a set of elongated, interlocking rails that frictionally engage and trap a cover that can be comprised of waterproof "spray skirt" material or nylon "pack" material. The cover, secured over the otherwise open top of a canoe, is a continuous covering, starboard to port and bow to stern, or includes coverings with seat openings, along the length of the hull. A stack of three rails comprise the preferred embodiment of the locking mechanism, with a rail base member fastening to the hull below and along the length of opposite and parallel gunwales; a rail locking member snaps on the base rail; and a rail cover having a plurality of T-node tracks similar to a mortise receives the male nodes or tenons extending outwardly from the locking member. The cover is stretched very tautly and held in a three-way lateral gripping action by the rail. The same rail system is used around the cockpit(s) to receive the spray skirt in a quick-release mechanism.

Abstract: An improved combing or opening roll assembly for open-end spinning machines includes means for cleaning the inner cavities by direct axial injection of compressed air into the cavity, and an outer surface configuration designed to inhibit or prevent accumulation of microdust and fibers thereon. One outer surface of the roller unit includes a color-coded speed indicating means which enables an operator immediately to visualize the relative speed of rotation, as a safety factor decreasing the likelihood that an operator would inadvertently touch the combing ring during rotation.

Abstract: A cup holder includes a movable adapter ring for use in selectively reducing the inner diameter of the larger upper socket that is the primary cup support. The large upper socket is movably secured to an underlying base member having an outer diameter sufficient to securely fit into the stationary cup holders found in most late model vehicles. The upper socket is movable in a lateral direction to accommodate use of two such supports in vehicle that provide two adjacently positioned cup holders.

Abstract: In protective illuminated vests and jackets a light enhancement means improves visibility and protects the enclosed light emitting bulb or diode. The light enhancement means is comprised of a transparent casing for housing a preferably screwbase lamp. The casing includes a cavity tapped into one end thereof for housing the lampbase and lamp, and a plurality of vertically spaced, horizontally extending apertures tapped through the casing to reflect light. The lamp is preferably mounted above the tapped apertures, beams light downwardly, and reflects in each of the apertures, giving the illusion of additional lamps.

Abstract: A control system and process method for reducing energy consumption of flight simulators includes electronic circuitry to automatically control the starting and stopping of the large motors that drive the hydraulic pumps for the motion system. The electronic circuitry monitors existing signals in the simulator motion and control loading cabinet and determines when the motors need to be started or stopped automatically. The circuitry generates the necessary outputs to start and stop the motors at the user level, and interfaces to the manual (user) motor control switches. The Energy Saving Control System (E.S.C.S.) provides a safe and reliable means of producing substantial electrical energy savings.

Abstract: A hydroponic gardening system includes an apparatus for supporting the growth of selected plants, which apparatus includes a housing having a lower-level nutrient tank and a plant support tray with a dual-level aeration chamber therein. Seed germination cubes are positioned on the tray adjacent the aeration chambers, and a uniquely designed capillary mat overlies the floor in both levels of the aeration chamber and underneath the seed germination cubes. End portions of the capillary mat extend down into the nutrient tank. Nutrient is conducted from the tank through the capillary mat to the plant root system which develops and grows in the aeration chambers. While the root system is nourished and moistened by the capillary flow of nutrient fluids from the nutrient tank into the aeration chamber, the structure of the dual-level aeration chamber is such that the roots are maintained in an environment of freely circulating air and conditions of 100 percent humidity.

Abstract: A set-up kit for surgical irrigation/aspiration equipment includes an irrigation tube and a suction aspiration tube for operative connection to an irrigation/aspiration machine. The aspiration tube is releasably connected to a hexagonally-shaped nozzle means on the machined fitting, which fitting is in turn releasably connected to a receptacle containing an air passageway on the irrigation/aspiration machine. This arrangement serves to isolate the aspiration tube from the machine. To further isolate, a disposable hydrophobic filter is placed in the branch line between the machined fitting and the aspiration tube.
