Abstract: A hollow rail structure directly extruded from aluminum in for pocket billiard table is disclosed to have an inner sidewall, an outer sidewall, a top wall, a bottom wall, ribs that define the inside space of the hollow rail into multiple compartments, a cover cloth locating groove longitudinally disposed on the top wall adjacent to the inner sidewall for the positioning of one side of a cover cloth, a longitudinal inside bottom channel longitudinally disposed inside the bottom wall adjacent to the inner sidewall for holding a wooden block for the mounting of the other side of the cover cloth and is fastened to the cover cloth locating groove, a longitudinal inside top channel formed inside the top wall, and a plurality of top locating holes in communication with the inside top channel and the outside space for the mounting of sights.

Abstract: In order to protect the appearance of and extend the life of a pool table, this protective device has been invented. It will be constructed from a lightweight yet durable material such as vinyl or cloth and be pressed, snapped or glued to the sides of the pool table. Separate devices will be used to protect the pockets of the pool table.

Abstract: An amusement device, including a frame made from four support legs which, running obliquely upwards toward one another, at their top end support a rotary member, an arm, one end of which is secured to the rotary member and which can be pivoted between the support legs, and a receiving device for people, which is suspended from the other end of the arm. The support legs, at their bottom end, are secured to a trailer by means of hinges, the hinge axis of which is oriented transversely with respect to the longitudinal direction of the trailer, and the axis of rotation of the rotary member is oriented in the longitudinal direction of the trailer.

Abstract: A cushion for a billiard table is disclosed. The cushion includes an extruded member having a substantially triangular or L-shaped cross-section and a layer of tape on one surface thereof for affixing the cushion to a billiard table. Also disclosed is an improved cue for billiards wherein a substantial portion of the weight of the cue is disposed in a distal portion of the cue located near the tip of the cue, which is used to strike a ball. The cue is preferably modular to allow substitution of various portions of the cue to permit it to be customized to a specific player. Also disclosed is a device for metering the speed of the surface of a billiard table. Also disclosed is a quick-change tip for a cue which includes an elastomeric material that is sized to snugly fit over the distal end of a cue to releasably secure the quick-change tip to the cue.

Abstract: A bumper for a table game includes a rigid form defining a generally horizontal upper surface and a vertically extending inner surface depending from the form upper surface. A first plastic cover of a first rigidity is disposed on an outer marginal portion of the form upper surface and a second plastic cover of a second rigidity has a first portion disposed on an inner marginal portion of the form upper surface and a second portion disposed on the form inner surface. A plastic cushion of a third rigidity is disposed on the second portion of the second plastic cover. The second rigidity is greater than the third rigidity, and the second plastic cover and the cushion (and optionally the first plastic cover) are of integral, one-piece, unitary construction formed in a single co-extrusion operation.

Abstract: A system is provided for covering the horizontal playing surface of a pool table and the elongate rail elements mounted along the edge of the pool table. A cloth cover is wrapped about an inside cushioned edge of the rail element. An upper groove is formed longitudinally in an upper surface of the rail element for receiving an upper section of the rail cover and a first spline is received in a relatively tight fit in the upper groove to hold the upper section of the rail cover therein. A lower groove is formed longitudinally in a bottom surface of the rail element and an elongate channel member is received by and attached within the lower groove for receiving a lower section of the rail cover. A second spline is received in a relatively tight fit in the channel member to hold the lower section of the rail cover therein. A cloth cover extends across the playing surface of the pool table and includes a side portion that hangs over an edge of the playing surface.

Abstract: A process in which copper, nickel, cobalt and molybdenum are recovered by leaching comminuted raw manganese nodules with an aqueous ammoniacal leach solution containing cuprous ions. An improvement is disclosed in which the metal values are extracted directly from the leach slurry with an organic extractant. To accomplish such extraction the amount by weight of solids in the slurry is maintained at less than 20 percent, the pH of the slurry is lowered to 9.5, the volumes of slurry and organic are maintained at a ratio so that the organic is the continuous phase and the organic and slurry are mixed with gentle agitation.
