Patent EP-0214164-B1 (EP)
IPC: F04C15/00
Filed: 1986-02-21
Granted: 1990-05-23
Abstract: The machine comprises two plate-like supports (9, 12) each provided with a crown of displacement blades (10), respectively displacement chambers (11), engaged into each other, and displaceable into a relative circular translation motion. The drive is implemented by a gear (7-9) at the center of the supports (9, 12), which exerts a force (FN) on one of the supports (9) at a radially displaceable position, said force presenting a radial component (FR) and a tangential component (FT). The direction of the force and the arrangement of the chambers (11) are so selected as to provide for a predetermined static position of the blades (10) in the chambers (11) independently of the wear. Optimum operation conditions are thus obtained with simple design and fabrication. For producing said pump, the plate-like supports are lapped pair-wise when they are in the state of blanks in conditions similar to the operation conditions and are then mounted in the machine .

Abstract: Clamping device for ensuring the contact and securing of the inner conductor of a coaxial cable in a coaxial cable connection device, with a lower clamping piece and an upper clamping piece which can be screwed tight against the lower clamping piece, in which the lower clamping piece is designed as a support element of insulating material and carries on its upper side a continuation connection contact, on which the cable inner conductor lies. At least one (9) of the components participating in the clamping of the inner conductor is designed and/or held by spring action in the clamping direction against the cable inner conductor (1). If the connection contact is designed as a longitudinally/extending contact element which runs transversely to the longitudinal axis of the inner conductor on the support element, the contact element (9) is held by spring action in relation to the support (3) in such a way that its surface which makes contact with the cable inner conductor (1) in the non-clamping rest position projects in relation to the surface of the support element.

Abstract: Dans le siège pivotant décrit, le dossier avec la partie siège présente une configuration pivotante autour d'un axe presque vertical, la surface d'assise pivotant autour d'un axe presque horizontal. Le siège est fixé à une structure porteuse de l'avion. L'invention consiste en ce que les parties porteuses du siège, comme la plaque d'assise (25), la plaque de dossier (27) se présentent sous forme de parties fraisées, et en ce qu'un ressort est actionné par le repliement vers le haut de la partie d'assise (2) et escamote le siège (1) dans un renfoncement (15). Ce siège se fabrique à un coût inférieur au coût actuel et se caractérise par un poids plus faible.

Title: Arrangement for centering a bearing unit of a pull-type clutch
IPC: F16D23/14
Filed: 1988-06-15
Granted: 1992-10-21
Abstract: Upon fitting of a so-called pull-type clutch between engine (1) and gearbox (4) in vehicles, difficulties arise in achieving correct coupling between the declutching mechanism (5) and the declutching bearing during bringing together of engine and gearbox. A bearing unit (15) including a declutching bearing is freely rotatable in a pre-assembled condition and needs to be centred in a certain angular position for correct coupling to be obtained. In order to achieve this centring of the angular position of the bearing unit (15) it is proposed according to the invention that the bearing unit is connected to a housing (6), which is fixed relative to the engine, via an extensible element (25, 28) by means of which the said angular position may be fixed.

Granted: 1992-05-20
Abstract: The invention relates to a straightness interferometer system, for measuring transverse deviations in the relative movement of machine parts. The preferred embodiment comprises a laser (30) which directs a single frequency laser beam, polarised in two orthogonal modes, along a principal axis P onto a beam splitter (24) which splits the beam into its two modes to provide two secondary beams (26, 28). One of the secondary beams (26) is undeviated from the principal axis, the other (28) is deviated through a small angle. A roof-top reflector-prism combination (30/40) is positioned in the paths of both secondary beams in a plane normal to the principal axis, the prism being arranged to deflect the deviated beam into a direction parallel to the principal axis so that both beams are reflected back to the beam splitter where they re-combine to form a combined beam. The combined beam is passed to a detector system (38) for detecting interference fringes reproduced from the combined beam caused by relative change in the path lengths of the two secondary beams as the reflector undergoes movements transverse to the principal axis. Three types of beam splitter are specifically disclosed, two of which show a further preferred feature of displacing one of the beams transversely to solve the dead path problem of a prior art system. A variety of combinations of the various elements of the preferred system are discussed but not all are illustrated.

Date Apr. 20, 1989.A control for the drive train of a motor vehicle is disclosed. The motor vehicle is equipped with an electronic engine power control and an automatic transmission. In addition to the position of an accelerator pedal (25) serving as the power control member, its movements as well as the movements of the brake pedal (16) are monitored by a computer (10) and predetermined motion sequences are selectively picked up as direct gear selection control instructions from the driver in order to possibly initiate gear changing processes after the premissibility of the new gear has been determined. Automatic upshifting processes are suppressed when the accelerator pedal is released as long as the number of engine revolutions remains below a predetermined engine specific maximum number of revolutions. On the other hand, movements of the accelerator pedal (25) are directly influenced by the computer (10).

Abstract: To create a roof or wall covering with fire-retardant properties, it is already known to fill channels (18) of a base layer (11), formed from trapezoidal sheet steel, of the roof covering (10) with water. It has been shown, however, that in the event of a fire leakages, leading to the discharge of the water within a short time, occur rapidly in the base layer (11), and consequently the water can no longer evaporate in order to fulfil the intended fire-protection purpose of dissipating the heat produced by the fire. In the invention, this disadvantage is eliminated. 
<??>According to the invention, a thickened fire-retardant liquid is arranged in the channels (18) of the base layer (11). As a result of this thickening, the liquid is unable to escape, or can escape only very slowly, from leaks in the base layer (11) in the event of a fire, thereby guaranteeing evaporation of the fire-retardant liquid for dissipating the heat energy produced in the fire. 
<??>The invention is suitable in particular for buildings with a flat roof covering.
