Title: Thermal insulation for rotatable coaxial tubes - protects rotational elements from fluid in tubes over wide temperature range
Inventor: OVIEVE GERARD
IPC: F16L27/08
Filed: 1982-02-03
Abstract: The radial thermal insulator is for a rotational element (1) between the ends of two coaxial tubes (2,3) for fluid transfer. It has a hollow cylinder (4) of insulating material, which fits into a housing (5) between the tubes and rotation elements. A stagnant vapour of the fluid provides extra insulation, when trapped in the space (6) between the cylinder and elements.

Title: Electrode for electroerosion tool - has fluid distributors fitting into holes to supply dielectric cleaning fluid
Inventor: PETITIMBERT JEAN
IPC: B23H7/22

Abstract: The electrode has holes for supplying the dielectric cleaning fluid and/or for de-gasing. A fluid distributor is pressed into each hole and consists of a cylinder (1) of the same size as the hole. Each cylinder has an axial hole that becomes crossed slots at its outlet end. The axial hole's diameter reduces where it joins the crossed slots. The relative dimensions of the slots and of the axial hole are specified.

Patent FR-2507431-A1 (FR)
Inventor: LEPOSA WOLFGANG
IPC: A01D78/10
Filed: 1982-06-10
Abstract: A haymaking machine is provided with at least one driven raking wheel mounted on an essentially vertical shaft supported by a supporting member. This raking wheel carries a number of raking tines which are arranged in pairs and are directed towards the ground and which are formed by the legs of helical springs. Every two helical springs coiled in opposition are connected to one another by means of a U-shaped loop which is fastened rotatably to the raking wheel. In order to provide a high-performance haymaking machine of simple construction, which, as a result of its tine design and tine arrangement, can either be used for tedding or swathing or, if appropriate, also, as a universal machine, be changed over from one mode of operation to the other, at least the middle parts of the tines (41, 42) of each pair of tines span an essentially vertical plane which extends at least approximately parallel to the centre line (53') of the helical springs (52, 53) which is arranged approximately tangentially to their circle of rotation.

Title: Method of fixing two coaxial tubes - entails driving oversize mandrel into inner tube causing it to flatten and fill holes in outer tube
Inventor: WALD JOSEPH
IPC: B23P11/00
Filed: 1982-06-15
Abstract: The method is for fixing a vehicle shock absorber case (1) in its holder (2-5). It uses holes (6) in the outer tube (2,4) to locate projections of the inner tube (1). Initially the inner tube in its smooth state, is placed concentrically in the outer tube which has been previously provided with holes. A mandrel (9) is forced into the inner tube, having an external dia. greater than the internal dia. of the inner tube, and flattening the inner tube to force its constituent material into the holes or cavities of the outer tube.
Patent FR-2531586-A1 (FR)
Title: AC regulator for flywheel-mounted alternator
Inventor: UBEDA JOSE SIRERA
IPC: H02J7/14
Filed: 1982-08-05
Abstract: The a.c. output regulator set point is in effect raised if the temp. as sensed by an n.t.c. resistor rises. A rectifier (3-6) is connected across the output winding (2) in which the magnet system (1) on the flywheel generates an a.c. voltage. The rectifier output is used to regulate the triggering instant of a thyristor (14) connected across the a.c. output of the winding. A switching transistor (7) is in series with the gate circuit (15,16) of the thyristor (14) and the d.c. supply from the rectifier. The transistor base voltage is also derived from the rectifier. In parallel with the base and emitter terminals of the transistor are a stabilizing capacitor and an n.t.c. resistor circuit (9,10,11). As the temp. rises, the ohmic value of the resistor (9)falls and in consequence the transistor turns on later in each rectified half cycle of the generator voltage. The thyristor therefore also turns on later causing the average a.c. voltage to the load to rise.
