Title: Improvements in or relating to storage devices
IPC: E04H6/12
Filed: 1959-12-21
Abstract: 927,899. Mechanical garages and storage systems. J. F. HOUSTON. Dec. 21, 1960 [Dec. 21, 1959], No. 43339/59. Class 78 (4). Platforms 13 (Fig. 1) for supporting vehicles in horizontally extending cells of a mechanical garage formed as a vertical rotating wheel are each mounted for rotation about the axis of the cell. In the form illustrated each cell is of hexagonal form and the platforms have arcuate portions 15 (Fig. 4) by which they rest on rollers 9 at the corners of the cells. The platforms may be biased to turn by gravity, or they may be driven from the drive to rollers 23 rotating the wheel, so that they always remain horizontal. The wheel may be supported partly by the rollers 23 and partly by a central shaft. Guides 19 on the platforms for supporting the vehicle wheels may adjust to accommodate different track widths. The gap between the guides is filled in so that oil dripping from one vehicle cannot fall on to another. Each cell may have a door, or, alternatively, the cells may be closed by cladding on a fixed superstructure provided with apertures at access points. Each cell may carry more than one vehicle. The lower part of the wheel may be below ground level and ramps may provide access. The invention may be applied to storing articles other than vehicles.

Patent GB-1000008-A (GB)
Title: Eccentric plug valve
Inventor: ROOS WILLIAM NORMAND
IPC: C08B15/10
Filed: 1962-11-21
Abstract: 1,000,008. Valves. DE ZURIK CORPORATION. Nov. 21, 1962, No. 44097/62. Heading F2V. A rotary-cylindrical through-way plug-cock has a cast bronze rotatable plug 11 eccentrically mounted to co-operate with an arcuate, eccentrically disposed seat 24; the two centres of eccentricity coincide when the valve is closed. The plug is journalled in sintered bronze bearings 32, 33, and is sealed in the body opening 20 by cruciform packing 39. To prevent the fluid pressure acting on the plug from closing the latter, a braking-ring 41 of material, e.g. nylon, is urged to engage a profiled end surface of the plug, the drag exerted by the ring considerably increasing as the axial compression of the ring is increased; such axial compression is provided by a spring 46 and the controlled fluid. To avoid washing out of the lubricant from the lower bearing the interior 29 of the plug is open to the bearing pocket 34 by a hole 50, which hole additionally serves to prevent transient pressure changes from immediately causing a change in the upward force acting on the plug. The plug interior 29 forms part of the flow passage through the valve when the latter is open. The seat or as shown, the plug face, is provided with a deformable insert 54 of rubber or synthetic resin; beyond the insert the seat and plug make metal-to-metal contact so avoiding damage to the insert as well as ensuring a fluidtight seal should the insert become destroyed. The insert may be smaller than the groove in which it is located and the latter may include a relief groove. A stop 61 in the east body co-operates with a protrusion in the plug to define the open position of the valve.
