Inventor: SCHRINNER DEE
IPC: E21B17/02
Filed: 2001-10-10
Abstract: A cable release apparatus includes a housing and latch mounted at one end of the housing. The latch has a central opening and a plurality of projecting members extending into the housing. A releasable connector is mounted inside the housing. An actuator has one end disposed in the central opening in the latch and another end in contact with the releasable connector.

Title: Indexable gravity flow shelving system
Inventor: MASSETT HENRY J JR
IPC: B65G1/08
Filed: 1999-06-21
Abstract: An indexable gravity flow shelving system provides resilient comb members along the front and rear rails of each inclined shelf to removably and releasably secure track members to the inclined shelf. Each resilient comb includes a row of downwardly-extending tangs that define slots therebetween to receive elongated flow ribs extending the length of the upper surface of each track member. The tangs contact the sides of the elongated flow ribs and prevent transverse movement of the track members. The spacing of the tangs allow for the shelving system to be used effectively with track members besides track members having elongated flow ribs. The resilient comb members deform and rebound to readily allow for rearrangement of track members within each inclined shelf. The resilient comb members can cooperate with price tag moldings along the front end rear rails of the inclined shelfs. The price tag moldings provide means for mounting labeling indicia in close proximity to columns of product units stored on the shelf, as well as means for receiving stop plates along the front and, if desired, the rear of the shelf to prevent unwanted spillage of product units. A desirable alternate embodiment utilizes adapter means to allow retrofitting an existing cantilevered gondola-type shelf with resilient comb members to form front and rear track interface means and convert the existing shelf into an indexable gravity flow shelf.

Title: A toy ball game with play mechanism
Inventor: RON CARSTEN
IPC: A63F7/24
Filed: 2000-07-05
Abstract: The invention relates to a toy ball game comprising a horizontally extending playface and having a play mechanism in the form of a toy figure arranged in such position on the playface that it protrudes thereabove and is arranged for being flexed away from a neutral position and by spring force revert to that neutral position whereby a face on the mechanism is able to transmit energy to a ball in order to cause the ball to move away from the mechanism and across the playface. The play mechanism is able to rotate about a vertical axis to enable the toy figure to face in the direction of his kick. From the mechanism an arm protrudes transversally and it is arranged to perform, in response to an influence exerted vertically by a finger, a flexing of the mechanism away from its neutral position. A face on the mechanism has a concave shape that matches the ball thereby allowing the ball to remain steadily positioned in contact with the concave face which means that the ball will always be positioned in front of the figure.
