Publication number: 20100024313Abstract: A movable cover structure for a fixed ground area, such as a swimming pool cavity (4), has a platform (15) which is displaceable horizontally from a position where it covers the fixed ground area to a position where it is retracted clear of such area. Square section channels (10) are inset along the inner surfaces of opposed long vertical side walls of the cavity (4) and house guide tracks (11). Guide wheels (19) are provided along opposed long sides of the platform (15) and engage with the guide tracks (11). Movement of the platform (15) is effected by a motor (12a) driving toothed wheels (13) which engage with toothed racks (20) provided on the platform (15). In the retracted position the platform (15) is stowed beneath an adjacent horizontal flat floor surface (6) within an inner space (9) below the surface (6). Sensors are provided to detect the presence of persons in the swimming pool.Type: ApplicationFiled: December 20, 2007Publication date: February 4, 2010Inventor: John Cartwright

Patent number: 7392901Abstract: A carrying case for sporting equipment, particularly hockey sticks and accessories such as pucks includes a block-shaped body which has an upwardly protruding carrying handle, a first longitudinally disposed, vertical side of the body which has formed therein a pair of longitudinally disposed, vertically spaced apart troughs, and a first side lid hingedly fastened to a lower edge of the body, the side lid having formed in an inner surface thereof a pair of troughs shaped similarly to those in the body. Stacked pairs of hockey stick handles are placed in either the lid troughs or body troughs, with the lid pivoted outwardly from the body to an open position; with the lid pivoted to a closed position in contact with the body, the lid and body troughs confront one another to form a pair of closed, longitudinally disposed channels which retain the handles therewithin. The lid is held in a closed position in contact with the body by releasably engageable fastener elements located on the lid and body.Type: GrantFiled: May 28, 2003Date of Patent: July 1, 2008Inventors: Timothy Frazer Cameron, Leonard John Cartwright

Patent number: 3948078Abstract: A mounting for a long horizontally disposed reciprocal ram of a can forming machine. The ram which carries a punch or mandrel at one end and is connected to a reciprocating drive at its other end is supported intermediate its ends from the machine framework by a plate which slides in a guideway. The plate, which extends parallel to the ram longitudinally thereof has a fixed connection at one end with the ram which is suspended beneath the plate. The plate which runs on guideways becomes very hot and is free to expand longitudinally independently of the ram since it has creep-accommodating connections through high thermal resistors with the ram at longitudinally spaced points which freely permit such expansion and resist transmission of heat into the ram.Type: GrantFiled: May 12, 1975Date of Patent: April 6, 1976Assignee: Continental Can Company, Inc.Inventor: William John Cartwright
