Abstract: A slide cover plate adapter and related methods of use for adding functionality to a semi-automatic handgun. The slide cover plate adapter replaces a factory slide cover plate located at a rear wall of a slide assembly in conventional semi-automatic handguns. The slide cover plate adapter includes a channel engagement portion and an accessory engagement portion that are spaced apart and coupled with a bridging member. The channel engagement portion operably couples to the slide assembly while the accessory engagement portion provides a convenient attachment point for any of a variety of handgun accessories.

Abstract: A filtration system is disclosed comprising a filter manifold and a filter cartridge. The filter manifold comprises a bracket, a valve, a manifold feed port, a manifold filtrate port, and a handle. The valve is held by the bracket and comprises a fixed portion attached to the bracket and a rotary portion. The handle is operatively connected to the rotary portion and comprises a cartridge lifter having one of a camming ramp or a camming lug lifter engagement feature. The handle is rotatable to a service position and a disengaged position, wherein the manifold feed port is blocked by the valve when the handle is in the disengaged position. The filter cartridge comprises a cartridge feed port, a cartridge filtrate port, and an external cartridge surface having one of a camming lug or a camming ramp for engaging the lifter engagement feature.

Abstract: The invention provides a new tennis backboard design. The backboard includes a firm backing layer underlying a soft deadening layer. The rebound of a tennis ball from the backboard is reduced as compared to rebound from a rigid hard-surface backboard. This allows a player to stand fairly close to the backboard, which reduces misses. The player can stand fairly close and hit balls hard against the backboard. Because the rebound is reduced, the ball simply bounces back softly and easily to the player, allowing the player to hit hard again from a fairly short distance. Thus, long rallies without missing are easily achieved. Since the bounce is reduced, the player can stand closer to the backboard, and therefore the backboard can be smaller than conventional backboards without the player missing the backboard. This allows the backboard to be light, portable, and easily stored.

Abstract: A connector for connecting plastic tubing includes a receiver having a captured ring seal, the ring seal for compressively forming a fluid seal when in engagement with the plastic tubing; and a plurality of inward directed angled fingers disposed in the receiver for compressively engaging the tubing, a force being exertable by the fingers on the tubing, the force acting to resist withdrawal of the tubing from engagement with the fingers. A method of connecting is further included.
