Patent FR-2226218-A1 (FR)
IPC: B29C65/08
Filed: 1974-03-25
Abstract: A sonic or ultrasonic apparatus comprises electroacoustic transducer means for providing vibratory energy applied to a workpiece to cause welding for instance. The transducer means is coupled by a set of leaf spring members to a stationary support. Reciprocating motion of the transducer means toward and away from the workpiece is accomplished by bending the leaf spring members using a motive means, such as a pneumatically driven piston. The leaf spring members yield in the direction of this reciprocating motion which substantially coincides with the axis of propagation of the vibratory energy, but exhibit rigidity along the direction normal to such axis.

Title: Distributor supplying water with adjusted total hardness - with internal sliding plugs and valves
IPC: F16K11/056
Filed: 1974-03-29
Abstract: Water distributor is intended to be connected to a water softener, to the mains supplying hard water and to the distribution system with the object of regulating the total hardness by means of valves which can be opened, completely or partially, on the various inlets. The body of the tubular distributor is open at the two ends and is fitted with lateral connections. A stem carries a stopper, a valve and another stopper. The stopper is extended by a guide-piece which can slide into an end-piece without affecting the flow of the softened water. At the other end of the stem is extended at (144) where it penetrates into a plug; it is screwed internally to receive a manipulating rod. By turning the rod, the sliding assembly on the stem can be made to advance or withdraw so that the softener can be put out of action and the valve between the stoppers can be closed or left partly open to allow a minimum passage of hard water to the distribution system. By closing and partly opening the valve, the total hardness can be regulated between a max. and a min. Once adjusted, there is no risk of stopping, or unduly limiting, the passage of hard water.

Title: Unwound wire tension control - uses magnetic clutch-brake with one plate attached to gear engaging quadrant with arm contacting roll surface
IPC: B65H59/04
Filed: 1975-07-07
Abstract: Regulating device to control tension of wire being unwound from a reel. The reel (1) is mounted on a shaft (2) which is extended (3) and supported in bearings (8). One plate (10) of a magnetic clutch is attached to the end of the shaft. The other plate is attached to a gear (18) which is mounted on a thread (14). Rotation of the plates moves them apart, increasing the air gap and reducing the braking effect. The gear (18) engages with a toothed quadrant (20), which is connected to an arm (30) in contact with the surface of the roll of wire on the reel. As wire is removed and the diameter reduces, the quadrant rotates so increasing the gap between the plates and reducing the braking effect of the spring (5). The tension of the wire is thus kept constant despite the reduction in diameter.

Title: Screw press for dewatering waste water sludge - which uses screw of constant pitch and outside dia. but tapered root dia.
IPC: B30B9/12
Filed: 1976-02-20
Abstract: A power driven screw conveys the sludge first through a drainage zone, i.e. over a drainage screen, and then through a pressing zone, i.e. iside screw casing. The press is adapted to unblock itself automatically in response to an undue pressure rise in the casing. Filtrate and dried sludge are delivered separately. The screw is pref. made to a constant pitch and constant outside dia. throughout its length. The screw thread root dia. pref. increases regularly from teh feed to the discharge end so that free space between screw and casing decreases progressively. The pressure zone casing is pref. made up of a stack of coaxial disks with narrow, interface filter channels which leak from the casing into a filtrate jacket. The disks are spring-loaded together so that blockge overpressure will part the disks to release blockage material. Used for dewatering waste water sludge to make it suitable for burning or other useful disposal. Initial drainage and pressure dehydration are combined in a single nit. The filter disks can be rapidly unblocked by slacking off the spring-loading.
