Abstract: A molded case, cassette type circuit breaker for a multi-pole electrical distribution circuit includes a number of cassettes equal to the number of poles in the multi-pole electrical distribution circuit and a pin disposed through each cassette. The pin is formed from a dielectric material. The pin may be further disposed through a portion of an operating mechanism for aligning the cassettes and the operating mechanism. Each cassette may include a rotor, a pair of electrical contacts, and a contact arm supported in the cassette by the rotor. In this embodiment, the pin may be a cross pin that extends between each rotor. The dielectric material may include phenolic, melamine, silicone, epoxy, polyester, fiberglass and the like. Alternatively, the pin includes a steel bar coated with the dielectric material, where the dielectric material may include, for example, epoxy, silicon, Teflon, and the like. A pair of end caps may be disposed over end surfaces of the rotor.

Abstract: A circuit breaker includes a housing, an operating mechanism, and a cassette. The cassette includes a separable current path having a movable contact arm, two arc receptors each disposed for receiving an electrical arc in response to a short circuit overcurrent condition, and two slot motors each disposed proximate the movable contact arm for magnetically driving the movable contact arm to a blown open position in response to a short circuit overcurrent condition. The slot motors each have two side legs opposing each other and defining a space therebetween for receiving the movable contact arm, each side leg having a magnetic core and an insulative layer and being biased toward the interior of the side walls of the cassette, wherein each side leg is restrained from being magnetically attracted toward the movable contact arm during a short circuit condition.

Abstract: A practice putting green assembly has a strip of artificial grass supported on an articulated multi-sectional frame. A plurality of motor/lift arm combinations can selectively raise or lower individual hinge points between the frame sections. A programmable circuit such as a microprocessor, is able to store a repertoire of programs of different movements responsive to the individual motor/lift arm combinations. This way, a series of topographies of the artificial grass strip may be selected by a player from a plug-in console connected to the programmable circuit. Putted balls are returned to a player over the grass surface by automatically inclining the target end of the grass strip toward the player, causing a pendulum controlled cup to empty and any balls on the grass surface to roll under gravity back to the player.

Abstract: An automated game assembly for use by at least one player, the assembly of the type having a basketball hoop mounted to a backboard, the basketball hoop and the backboard being mounted on a vertical support, the game assembly comprising means for rotating the basketball hoop and the backboard about a vertical axis, the vertical axis extending through the basketball hoop and offset horizontally from the backboard and the vertical support, and means for linearly displacing the basketball hoop and backboard away from and toward the player.

Abstract: A golf putting assembly comprising a playing mat having a putting end, a ball cup end, and a ball cup in the ball cup end, a mechanism for adjusting the playing mat to a selected one of multiple topographies, and a ball return mechanism for inclining the ball cup end of the playing mat toward the putting end, thereby gravitationally causing all balls on the ball cup end to return to the putting end.

Abstract: A gold putting assembly comprising a playing surface having a target hole, elevation means for adjusting the topography of the playing surface, and ball return means that elevate an entire section at the end of the playing surface nearest the target hole such that an incline is created, the incline causing any balls thereon to move away from the incline.

Abstract: A putting green assembly, the assembly comprising a playing mat, a ball cup and a combination means for adjusting the topography of the green and for returning a plurality of balls, the combination means being adapted to elevate at least one flattened area of the playing mat and create an incline therein, the incline changing the topography of the playing mat and further causing the plurality of balls to move away from the incline of the playing mat.

Abstract: A dart game assembly comprising a housing element, a spider, a plurality of target plates and a back plate. The spider is generally circular in shape and comprises a series of circumferentially and radially extending ribs integrally molded with the housing element from a single piece of material. The circumferentially and radially extending ribs form interiorly spaced cavities that are adapted to receive the plurality of target plates. Each of the plurality of target plates comprises several target segments which are interconnected and capable of independent movement upon being impacted by a dart. The back plate is integrally molded from a single piece of material and is attached to the housing element.
