Title: Feeder for finishing grinding machines - tool is moved by a piston according to tool wear
IPC: B24B19/06
Filed: 1974-05-13
Abstract: Feeder for finishing grinder has a piston which moves in a chamber acted on by the control pressure where the piston is connected to a tool in a grinding stone holder, which moves onto the workpiece under the control pressure according to its increasing wear. On reaching the max. allowable degree of wear of the tool, the piston-releases a switch line which picks up the control pressure and passes to a switch device with a pressure switch which switches off an operation of a pressure generator.

Title: Bicycle lighting system including direction indicators - has batteries inside saddle support tube and dynamo inside bottom bracket
IPC: B62J6/06
Filed: 1974-07-03
Abstract: A lighting system for a bicycle or light motorised cycle uses the saddle supporting tube of the frame to house a cylindrical set of batteries. These batteries may be a set of rechargeable nickel-iron cells (20) resting on a pin (21) so that they do not make contact with the bottom bracket (16) and can be used to power a headlamp unit which also incorporates direction indicator lamps each side of the headlamp, and also to power a tail lamp unit also incorporating indicator lamps each side. These rechargeable cells can then be charged by a dynamo housed completely inside the bottom bracket, protected against weather conditions driven directly by the pedals, the whole controlled by a switching and charging circuit.
Patent FR-2241040-A1 (FR)
Title: Appts. for reducing pipe mains hammer blow - is for power station boiler water feed systems using three-way valve
IPC: F16K39/02
Filed: 1974-08-09
Abstract: Power stations have rapid acting reversing valves for regulating feed water passing through preheaters. These give rise to pressure waves which travel up the feed pipe and can cause much damage. The patent covers a system in which the three way cock is first reversed. At the same time a stopping element closes relatively slowly. This is followed by the closing of a throttling mechanism in an exhaust circuit which short circuits the closure of the three way cock, i.e. into the pipe under pressure. This lessens considerably the risk of hammer blow.
Patent FR-2245874-A1 (FR)
Title: Magnetic rotor made from hollow cylinder - has permanent magnet on rotor with radial magnetic field and magnet rings on stator
IPC: F16C39/06
Filed: 1974-08-13
Abstract: There are normal ring magnets on the ends of the rotor but, in addition, there is a permanent magnet ring with radial magnetic field opposing the stator winding. This generates an axial force on the rotor. On the stator there is at least one sensor measuring the axial position of the rotor. A regulator varies the current in the windings, depending on the sensor. This keeps the rotor stable. The magnet rings on the rotor are made from ferromagnetic material. By using a series of ring magnets it is possible to provide progressive radial and axial stabilisation. The outer face of the rotor and the inner surface of the stator are coated with a thin smooth layer of non magnetic high conductance material.
