Patent FR-2295619-A1 (FR)
Title: DC traction motor control - uses an additional rotating outer yoke to modify flux linkages
IPC: H02P7/282
Filed: 1975-11-19
Abstract: This electrical traction motor uses the principle of varying the air gap flux of a DC motor in order to obtain power control. The stator of the motor is composed of soft iron poles (9) alternately located between radial magnets (10). Outside the stator is another yoke of alternate iron (7) and non-magnetic (8) segments. This yoke is free to rotate. Its rotation modifies the bridging effect of the poles by the segments and therefore modifies the stator flux linkages. The outer yoke can be directly linked to the accelerator of the vehicle. This method of control reduces the cost of the regulating system compared to armature current control.

Title: Silt cleaner for oyster beds - consists of support belt on which are suspended straight and spiral thongs to generate suspension of particles washed away by tides
IPC: A01K63/10
Filed: 1976-07-23
Abstract: The oyster bed cleaner consists of a band or support on which are fixed flexible strips, some of which are straight and others spiral.

Patent FR-2343109-A1 (FR)
Title: Silent action combination lock - has disc cam rotated to allow latch arm to fall into slots across number wheels
IPC: E05B37/04
Filed: 1977-01-24
Abstract: A combination lock is designed so that there is no noise as the number wheels are rotated, thus making theft correspondingly difficult. The wheels (11) are rotated until all the recesses (12) in them are in line at the top. A latch control arm (18) can then be released so that a cross piece (17) extending sideways is lowered into these recesses. The arm can then be slid back by rotating a special cam disc, pulling the latch blade (20) back to open the door. To lower the control arm, a button mounted on a spindle (10) passing through the wheels is pushed against a dished spring so that a cam disc (13) is pushed sideways. This allows the nose (22) of the cross piece to be disengaged from the edge (14) of the cam, and rest on a smaller diameter part (13), and the cross piece can then fit into the wheel recess. Further rotation of the cam disc allows the nose to fit into a groove in this smaller diameter part, so that the control arm is pulled back.
