Title: Paving slab for curved paving pattern
Inventor: RUCKSTUHL WILLI
IPC: E01C5/06
Filed: 1986-07-23
Abstract: The paving block inner and outer radii (Ri, Ra) are equal, and the centres of the radii lie on the centre line of the block a distance (h) apart. The side edges are curved at identical radii with their centres on a line intersecting the block centre line between the centres of the inner and outer curves. The distance between the centres of the edge curvatures equals the sum of the inner (Si) and outer width (Sa) of the block. The sum of the included angles of the three concave curves equals the included angle of the convex curve, with the included angle of the side edge curve (alpha) being 1/n by 360 deg. where n is an integer, pref. 16.

Title: System allowing the use of the pressure in a water network to actuate jacks after transfer to an intermediate liquid, which is particularly adapted to the opening of door leaves
IPC: E05F15/02
Filed: 1986-10-23
Abstract: Device allowing the use of the pressure of the water in the network to actuate a jack. The invention consists in transferring the pressure of the water in the network to a liquid which is less sensitive to low temperatures, has a different density, and has lubricating properties, which actuates a jack, for example a double-acting jack. It consists of two enclosures 6, 15, in each of which the lower orifice is connected by a solenoid valve to the network 2, 12, and to a discharge solenoid valve 4, 13. The top of the enclosure contains a transfer liquid, and is connected to a chamber with a double-acting jack, in the case of one enclosure, and to the other chamber, in the case of the other enclosure. The control for opening the solenoid valves 2 and 13 comes from the extension of the jack, the opening of the solenoid valves 4 and 12 causes compression of the jack. The device is in particular adapted to controlling gate leaves.
