Patent EP-0436432-A1 (EP)
Inventor: HUIGNARD JEAN CHRISTIAN PHILIP
IPC: G06F17/40
Filed: 1990-12-21
Abstract: The method is intended for the detection, the recognition and the use of significant sequences of signals modulated on to a carrier frequency, mixed with other signals, of the type according to which a test frequency is generated, corresponding to the sequence to be recognised, both of the coordinated profiles, then the electrical signals of these sequences are transformed into ultrasound signals, then the test sequence (X) and a received sequence (W) are led, after transformation into ultrasound signals, to a signal crystalline body (50) of the Bragg cell type, so that these two sequences (X and W) traverse the said single crystalline body (50) in parallel. According to the invention, a laser beam (Y) is directed simultaneously into the same single crystalline body (50), but in a direction substantially perpendicular to the foregoing, that is to say at the Bragg angle so that the rays of the laser beam are deflected in one direction by the test sequence (X) and also in the same direction by the received sequence (W), then the resulting rays (Z) are analysed on their output from the single crystalline body (50), the deflected rays (Z4, Z'1-Z'2) are extracted from the resulting rays (Z), then, for each bit of the sequences (W and X), the non-deflected rays (Z), the rays (Z', Z'1) deflected once and the rays (Z'2) deflected twice are examined so as to compare them. <IMAGE>

Inventor: BRAUN BODO
IPC: H02B1/21
Filed: 1990-11-05
Abstract: A switch gear unit has withdrawable apparatus supports (1) which can be connected by means of isolating contacting devices (3, 16; 7, 17) to supply busbars (3) and outgoing conductors (4). The busbars (3) are arranged one behind the other in the movement direction (5) during withdrawal. A common drive device, consisting for example of a shaft (12), pinions and toothed rods, operates both isolating contact arrangements simultaneously. This results in a reliable mechanical lock of the apparatus support (1) against displacement when the isolating contact arrangements (3, 16; 7, 17) are closed.

Filed: 1990-03-01
Abstract: The protective device against an overheating, in particular by fire, of individual or batteries of pressure vessels (10) of a length (1) of at least 1.5 m serves for the storage and/or transportation of high- pressure gases. The pressure vessels (10) have at least one end cap (14) with a valve (18) or an end plug (20) with a melting plug (22) of an alloy melting at a low temperature. On at least one end cap (14) a pressure pipe (24), communicating constantly with the interior of a pressure vessel (10) branches off, which pressure pipe is led in axial direction (A) along at least a part of the pressure vessel (10). At intervals (a), essentially T-shaped fittings (26) are installed in the pressure pipe (24), which fittings have in their branching-off leg a melting plug (22) of an alloy melting at a low temperature. A blindly ending pressure pipe (24) is closed off by such a melting plug (22). The protective device is primarily used on pressure vessels of aluminium, in particular with a fibre-reinforced jacketing (12).

Abstract: La présente invention se rapporte au domaine des poches autogonflables conçues pour être utilisées comme auxiliaires de décharge dans des distributeurs. Dans les poches autogonflables de la technique actuelle, qui se composent généralement de compartiments adjacents contenant un premier réactif en solution aqueuse et un second réactif soit en solution aqueuse soit sous forme solide, il est difficile de maintenir une production de gaz uniforme dans la poche, ce qui a pour résultat un écoulement irrégulier ou inconsistant depuis le distributeur. La présente invention améliore l'uniformité de production du gaz, en plaçant le second réactif uniformément précipité dans un milieu de suspension hydrodispersible. La poche expansible (2) se compose de plusieurs compartiments contenant un premier réactif en solution aqueuse (30), telle qu'une solution d'acide citrique, et une suspension de gomme hydrodispersible (34) contenant un second réactif précipité, tel que du bicarbonate de sodium. Le milieu de suspension hydrodispersible (34) peut également contenir un agent de nucléation et un agent tensio-actif.

Abstract: The construction according to the invention of the latching device permits a fixed frictional connection of telescopically guided tubes by relatively simple screwing together, and hence reliable transmission of the forces occurring. To this end, a clamping sleeve 1, which is provided with a longitudinal cut 2, is used, whose outer wall runs in a conically tapering manner from the centre circumferential line to the two end sides and which can be inserted, up to approximately the centre circumferential line, into the mating retaining piece 4 which is arranged fixedly on a pipe end. A connection nut 5 can be fitted to the mating retaining piece 4. The parts of the latching device are produced from plastic, using the injection-moulding process.

Abstract: 5 n7 An improved collar assembly (11) adapted for easing the disassembly of stacked members on a shaft (50) subjected to compressive loading is disclosed. The collar assembly (11) includes a pair of collar members (10,12) which are mounted contiguously abutting one another along a planar angulated interface. One of the collar (10) members defines a bore therethrough configured to closely correspond to the exterior diameter or exterior configuration of the shaft (50) in which the collar assembly (11) is to be mounted. The second collar (12) assembly defines a bore therethrough which is dimensioned to be substantially larger than the shaft (50) exterior configuration in which the assembly is to be mounted. The disparity in the bore sizes permits the second collar (12) to be displaced laterally as well as axially along the shaft with respect to the shaft (50) and along the planar interface of the two-collar members. The two-collar members (10,12) define the respective exterior engagement surface adapted to engage and otherwise abut against a member stacked on the shaft. The distance between the opposing engagement surfaces thereby adjustable dimensionally as the second collar member is displace along the surface of the first collar member. A cover (14), adapted to retain the two collars (10,12) in alignment one with the other, is configured to be positioned about the two collars. One or more jack screws (97) may be mounted within the second collar member (12) to releasably retain that member in a selected orientation vis-a-vis the shaft (50).
