Title: Rotary piston engine - in which piston movement is transmitted to a concentric rotating centre shaft
IPC: F01C1/10
Filed: 1973-10-01
Granted: 1975-04-25
Abstract: A planet wheel and eccentric disc transmit the eccentric movement of the piston to the concentric rotating movement of the shaft. The piston is fitted with a radial surface shaped in relation to the housing to produce several recesses in the inner space between housing and piston at a distance from each other. These recesses include at least two separate combustion chambers each fitted with sparking plugs. There are fuel inlets and exhaust outlets and the radial surface of the piston is shaped to include projections which, during rotation of the piston, successively compress the fuel, push out the exhaust gases. The eccentric rotation of the piston causes a degree of co-ordination between the piston projections and the inner surface of the combustion chambers so that the fuel inside the combustion chambers is in a degree of max. compression when the sparking plugs start the combustion process.
Patent FR-2249560-A5 (FR)
Title: Method of constructing a vault or pit - has side walls joined to outwardly convex ends of end walls
IPC: E04H13/00
Filed: 1973-10-29
Granted: 1975-05-23
Abstract: The side walls are made shorter than usual, whilst the length is regained by making the end walls (18) convex outwards. This confers the two advantages that since the sidewalls are shorter than usual, they can be made thinner yet resist the same ground pressure and since the end walls are convex outwards they can also be made thinner and lighter. Corner joints are made by tongue and groove construction and the angled shape of the corners avoids the necessity for digging a hole with perfectly square corners to minimise the amount of earth removed. Tongues (42, 44) are formed along the tops of the walls to locate the bottom edges of the walls of higher sections of the vault.
Patent CH-696757-A5 (CH)

The piece is supported by a work table (18), and a wire (14) is displaced along an alternating or direct movement. A value representative of the supporting force is measured, and wire sawing of the piece is carried out by considering the value during the sawing. An independent claim is also included for a wire sawing device comprising a frame.
