Abstract: 1,190,895. Swimming pools. GEMEENTE ROTTERDAM. 13 June, 1968 [19 June, 1967], No. 28237/68. Heading A4N. A swimming pool has an impervious interfloor, with edges flexibly sealed to the walls, which can be raised and lowered by means of a pumping system which draws water from above and below the interfloor through discharge lines and supplies an equal volume of water through supply lines to both levels, the discharge and supply lines contain adjustable valves whereby net transfer of water from below the interfloor to above it and vice versa can be effected to adjust the position of the interfloor. In a preferred embodiment the water level is kept at a constant height (6), Fig. 2 (not shown) by means of a recessed circumferential drain (7). A flat plate-like interfloor 8 is arranged to be moved parrallel to the pool bottom from a position at minimum water level above the interfloor to a position at maximum water level above the interfloor and vice versa, as shown. The interfloor is sealed around its edges by means (27) and is maintained horizontal by a guide such as lazy tongs 9. When the interfloor is moved to its lower position, per time unit more water is fed via a supply device 24 to the water space above the interfloor than is removed therefrom via a discharge device 21 by controlling the valves 28-31 which further ensure that more water is removed via a discharge device 13 from the water space below the interfloor than is fed thereto by a supply device 14, so that the interfloor is moved downwards by the water pressure. The opposite process raises the interfloor.

Title: Machine for screwing up and unscrewing bolts and nuts, for the rail securing means of permanent way
IPC: B23P19/06
Filed: 1957-09-13
Abstract: 846,936. Screwing-up and unscrewing bolts and nuts. PLASSER, F., and THEURER, J. Sept. 13, 1957 [Sept. 27, 1956], No. 28943/57. Class 83 (3). A machine for screwing-up and unscrewing bolts and nuts, more particularly for use on railways, has a key 28 driven hydraulically at a speed determined by the torque applied. The machine consists of an hydraulic motor 12, supplied with fluid through a hand-controlled reversing-valve 20 by a swash-plate pump 9, and a power-regulator 10 having a piston 16 actuated against a spring 17 by pressure in the discharge-pipe 15 of the pump. The piston 16 acts through a pivot 11 on the swash-plate of the pump 9 to vary the pump output. In operation, the pump supplies fluid through pipes 15, 19, and valve 20 to rotate motor 12 and drive the key 28 through gearing 13. As the torque increases, an increase of pressure in pipes 15, 19, acts on piston 16 through a pipe 18 to reduce the pump-output, thus reducing the rotational speed of the key but allowing the pump pressure, and hence the torque, to increase, the power output of the pump remaining constant. When the nut &c. is set to the required amount, further rise of pressure in pipe 19 opens a reliefvalve 26 to discharge the pump output to the reservoir 14, and rotation of motor 12 ceases. The machine is mounted on a truck 1, having a handle 3 by which the truck is moved on the rails, the handle also serving to rotate the truck about a vertical axis and align the key over the nut &c.
