Abstract: A simple pneumatic device for use in comparing and matching curling stones, and evaluating ice surfaces and sweeping broom efficiencies is described. A pneumatic cylinder, charged by means of a compressed gas, is placed against the backboard of a rink and operated to propel a curling stone with a predetermined and accurately controlled force along a sheet of curling ice.

Abstract: A pneumatic toy including a board provided with a runway, a body for running along the runway, an air chamber formed within the board, a blower for supplying air to the air chamber, a plurality of holes associated with the board which communicate with the air chamber and which are inclined relative to the board to direct air against the running body to propel same along the runway.

Abstract: A unique skill-action table game is provided, which consists of a rectangular shaped game board defining a court having a center line which divides the court into two playing areas, with two end goal lines and two side lines. A small lightweight hollow ball is also utilized, when the game board is elevated at least two players can each stand behind one of the end goal lines and try to blow with their mouth the small lightweight hollow ball over the opposite end goal line, to receive a point each time during the play of the game.

Abstract: A law enforcement baton for enhanced suspect control and apprehension comprises detachable, coextensive, proximal and distal lengths with a handle portion removably perpendicularly attached thereto with the handle portion and distal length being of identical construction and interchangeable upon the baton. The distal length includes a central bore with a plurality of reduced diameter bore holes extending parallel thereto in annularly spaced relation thereabout. A net having a plurality of elastic lines with retaining elements attached thereto is removably positioned within the central bore and the plurality of bore holes, respectively. The proximal length includes an opening wherein a compressed air canister is removably inserted with the sealed end thereof being in fluid communication with the bore openings in the distal length when the proximal and distal lengths are attached together.

Abstract: A game apparatus which consists of a substantially rectangular base having a flat surface. A vertical plate is suspended over an end of the base by a support and has a hoop horizontally attached to the plate. A catapult is pivotally mounted to the opposite end of the base and has a receptacle for holding a ball which can be projected toward the hoop. An air nozzle, which is connected to a pressurized air supply, can be used by an opponent for deflecting the path of the ball after it has been projected from the catapult.

Abstract: A toy vehicle and a handheld pneumatic launcher combination includes a piston and an elongated hollow cylinder with a flange adjacent one end of the cylinder providing grips for a child which simulate an airplane control yoke. While supporting lateral extensions of the flange with the fingers of each hand, the child's thumbs are free to press upon an actuator at one end of the piston forcing the piston head into the cylinder. Attached at the other end of the elongated cylinder, in pneumatic communication with the cylinder, is a launch tube that fits into a socket adjacent the bottom of a toy vehicle that is made predominantly of a lightweight plastic foam. The axis of the launch tube is preferably offset from the axis of the cylinder. In addition, the launch tube is tapered and has a closed end with perforations through the sidewalls of the tube adjacent the closed end.

Abstract: A baseball game apparatus including a simulated baseball diamond fitted with an air jet for projecting a low density ball toward a batting device by which the ball is struck, in the right hand or left hand mode, with various degrees of batting power while the ball is airborne. The batting power is adjusted, within the control unit, by interchangeable gears or handles each having a different length lever arm. The ball is projected toward the batting device by an air jet and lofted through the strike zone by a ramp.

Abstract: A toy car collision set (10) in which children attempt to crash nonsteerable unpowered cars (28, 30) at an intersection (12) when travelling in either the forward or reverse directions. The set includes at least two sets of tracks (14, 16, 22, 24) connected together at the intersection (12). A launcher (18, 20) is connected at one end of each of the tracks, and includes a piston assembly (34, 38) having a 5 to 1 compression ratio to be easily operated by a child hitting or pushing the top of the launcher. At the other end of each of the tracks, an elastic return means (26, 27) returns the launched cars along their respective tracks, if the car has not crashed at the intersection. The return means includes an elastic strip (52) stretched across the track to rebound a car striking the strip back along the direction in which it came to either strike another vehicle, at the intersection, or to be returned to the launcher for another launch.

Abstract: Apparatus for conducting sports and games on a slippery solid playing area surface comprises one or more doughnut-shaped streamlined discs which include a self-contained propulsion device. Each disc optionally carries an operator and includes around the perimeter thereof a resilient collision bumper. The surface of the playing area comprises a slippery upper layer and a solid underlayer. Each disc, while being supported on the surface upper layer in sliding relationship, is slidingly moved over the surface upper layer by propulsion devices acting relative to the underlayer. Such propulsion can be generated, for example, by electromagnets, motors, jets and the like. Various playing area surface compositions are also disclosed.

Abstract: A portable pneumatic action game for two opposing players has a base including a central raised hollow core supporting a playing surface and oppositely extending end sills. The playing surface has an array of separate elongated channels, each with an aperture at each end. A transparent cover extends over all of the channels. Slots in the cover permit insertion of a playing piece into each channel. Slidably mounted on each of the sills is a manual air pump and nozzle which can be moved by the player along one end of the channel array to selectively register the nozzle in pneumatic communication with the aperture of one channel to propel the playing piece toward the opposite end. An opening is provided in the bottom of each channel adjacent each end for the playing piece to drop down into the hollow central core for later tallying of the respective players' scores.
