Title: Control circuit for converter fed DC motor - with speed feed back as the only controlling signal
IPC: H02P7/293
Filed: 1974-12-16
Abstract: The application is mainly to high speed machine tool drives, where it is desirable to reduce time delays in the control circuit to a minimum. The elimination of a current regulating circuit helps this objective, and may be achieved by using direct and integrated speed feedback. The feedback signal from the tachogenerator and the reference are fed to a proportional amplifier with two output branches. One goes direct to a summing amplifier, and the other via an integrator, to the same amplifier, which in turn controls the rectifier gating circuits. The magnitude of the proportional amplifier feedback, and the integration time of the integrator are made inversely proportional to the speed control and/or reference value.

Title: Shower head for sanitary douche system - has selector cap to deliver full bore or spray flow supply
IPC: B05B1/16
Filed: 1975-05-20
Abstract: A shower head for a sanitary douche system has an external cap (20) with a channel system which leads from the floor (12) of the body box to a central flow space (25) of the cap (20). Another channel system leads from the box floor to a concentric flow chamber (26). Rotation of the extension body box allows either a full bore stream or a spray type delivery to be selected. The usual side control lever is no longer necessary and the outward shape reveals no functional parts. The head can therefore be shaped as desired, presumably according to the latest fashion. This is easily carried out since it is a single unit.

Patent FR-2335816-A1 (FR)
Title: Repeater mechanism for fixed gun barrel - with chambers for keeping combustion residues from moving parts
Inventor: PRADILLON MICHEL
IPC: F41A21/28
Filed: 1975-12-16
Abstract: Repeater mechanism for a fixed gun barrel is designed for exploding a cartridge arranged opposite an escape orifice for the gases produced by the explosion. The charger, of plastics material, moves in the passage perpendicularly to the gun and the guide for the precussion device. The passage has guide faces against which the charger can slide. There is a contact zone between the charger and the gun. When a cartridge is fired, the gases escape chiefly through the fun barrel but also along the contact zone., The combustion residues follow the same paths and are localised in chambers. These accumulations are out of the way and do not interfere with the normal repeating mechanism. After long usage the chambers can easily be cleaned without dismounting the appts. Frequent repeater action is possible without the risk of jamming the moving parts by combustion residues; so the amount of dismantling and cleaning is much reduced. The mechanism is partic. interesting for use with target pistols, bolt funs and humane killers for animals.
