Title: Warp
IPC: D03C9/02
Filed: 1979-09-25
Abstract: In a warp of injected plastic is anchored a thread guide ring (10) which may be made of case-hardened or stainless steel. The anchoring is effected by molding the plastic material of the warp about the ring (10). The ring (10) may have a substantially half moon-shaped profil, the edges thereof being sunk into the plastic material to insure a passage without catching. The elongated parts (22, 24) and/or the region (16) of the ring (10) have a substantially ovale cross section. Such a warp presents the advantages of a metallic warp with regards to the wear of the ring and the advantages of a non metallic warp with regards to its light weight.

Title: Electrolysis device.
IPC: C25B9/17
Filed: 1979-12-18
Abstract: The device comprises a tank filled with electrolyte, flat electrodes which are stacked horizontally so as to rest upon one another under the action of gravity and at least a certain number of which are consumable. Two successive electrodes are separated by spacer elements having the same thickness and formed of material which is inert to electrolysis. The contact surfaces between the spacer elements and the electrodes therefore permit substantially uniform erosion of the consumable electrodes over their entire surface and the spacing between two consecutive electrodes thus remains constant.

Title: Electrohydraulic rotary brake.
IPC: F16D57/06
Filed: 1980-04-18
Abstract: An electrohydraulic rotary brake comprises an inner core, at least one energizing winding, a cylindrical amagnetic insert and an annular part outside the core and the insert. A cylindrical bore is excentric with respect to the cylindrical peripheral surface of the insert, recesses being provided with magnetizable sliding vanes and a brake fluid. On a rotary shaft, are mounted lateral flanges in fluid-tight manner, the inner core being fast to the rotary shaft and to the insert, all three being arranged so as to constitute a rotor for the brake. The annular part outside the core and the insert constitutes an annular stator to which the lateral flanges are fixed and with the bore excentric with respect to the peripheral surface of the insert constituting the outer part of the rotor. The recesses are formed in the cylindrical amagnetic insert and extend radially therein on both sides so that the vanes are movable between a position of complete freedom of the rotor with respect to the annular stator, in which they are positioned close to the rotor core, and a braking position in which they are positioned close to said annular stator, so that, under the effect of a variation in a pre-determined sense of the current passing through the energizing winding, the vanes can be attracted towards said stator and thus define peripheral chambers of different volumes which, by the forced passage of respective volumes of fluid from one chamber to the other, cause between the vanes and the stator a severe throttling and thus the braking torque of the rotor.

Title: Mixer.
IPC: B01F1/00
Filed: 1983-08-18
Abstract: A device for adding a solid additive to a liquid has a liquid inlet, a liquid outlet and a receiving container for the solid additive in the form of a tablet or bar.

Title: Coin level detector.
IPC: G07D1/00
Filed: 1983-12-12
Abstract: A pivoted actuator 5 formed as a casting or moulding and including a curved surface 4 projects through a longitudinal slot 3 in a coin tube 1 and operates as a shutter 7 which makes and breaks an electric circuit by interrupting a beam of radiation between a source 11 and a detector.
