Abstract: A polyvalent suspension balance for the assembly lines of manufactured goods, especially motor vehicles, involving at least one overhead device for coupling to an aerial conveyer drive is disclosed. The suspension balance consists of two vertical curved arms, shaped roughly like a wide-open C, each of which separately connects an overhead coupling piece to at least one lower and separate anchoring member for the substructure of the product to be assembled. The said curved arms are articulated about a more or less vertical axis which has great freedom of movement, thereby making it possible to gain easy access to all of the products during all stages of their assembly. Application is to assembly lines for relatively bulky and complex manufactured goods, especially to the production lines of motor vehicles.

Abstract: The arrangement consists of a nonreturn valve (5) built into the delivery line (3) of the compressor (1) and of a pressure unloading valve (6), the closure element (9) of which controls an unloading port (10) and is actuated by a diaphragm (11). The diaphragm is acted upon in the closing direction of the pressure unloading valve by the pressure prevailing in front of the nonreturn valve in the delivery direction and is acted upon in the opening direction by the pressure prevailing behind the nonreturn valve. The pressure unloading valve is thus held closed by the pressure difference arising due to the pressure drop across the nonreturn valve and opens as soon as delivery ceases and with it the pressure drop no longer exists. <IMAGE>

Abstract: Coulee de materiaux en fusion, dont la solidification comprend une expansion suivie d'une contraction, par exemple des alliages de fonte grise, de la fonte nodulaire, etc. Le materiau en fusion est envoye dans une cavite (2) dans un moule (1) via un ou plusieurs becs de coulee (5) prolonges par des entrees (7) en communication directe avec la cavite (2) du moule, apres quoi la connexion de la cavite (2) du moule a l'environnement est bloque a un moment choisi de telle maniere qu'au moins une partie de l'expansion et de la contraction qui s'ensuit aient lieu dans l'espace ferme par ce blocage. Ce qui est caracteristique dans l'invention est que le blocage est effectue en refroidissant une partie du bec de coulee (5) de maniere telle qu'un bouchon de materiau solidifie (10) se forme dans le bec de coulee (5) avant que le materiau present dans l'entree (7) ne se solidifie. Selon une forme preferentielle de realisation, le refroidissement est provoque en introduisant un bouchon, par exemple du sable, dans l'embouchure de l'entree de coulee (5), de preference un bouchon ayant une section diminuant dans le sens d'introduction. L'invention permet d'utiliser l'expansion de la coulee pendant la solidification pour empecher le developpement de cavites dans la piece coulee dues a la contraction qui s'ensuit, tout en laissant une liberte totale en ce qui concerne les dimensions du systeme de coulee.

Pour ce faire, lors de la mise en service de l'unite de source de courant, la source de courant d'entrainement est mise en service apres que les organes de detection (603, 703) aient detecte l'etablissement complet de tensions dans la source de courant de circuit de commande tant dans l'unite principale de source de courant que dans les unites supplementaires, et apres que les organes de detection (104, 704) aient detecte l'etablissement de tensions dans toutes les sources de courant dans les deux unites. Lorsque l'etablissement de toutes les tensions dans toutes les unites de source de courant est detecte (606, 706), un signal de validation (EN) est produit qui met en marche simultanement les deux unites de source de courant. Lors de l'arret de l'unite de source de courant ou en cas d'anomalies de la source de courant, des circuits de detection (603, 604, 703, 704) detectent cette condition et arretent le signal de validation, ce qui a pour effet de mettre hors service dans l'ordre la source de courant d'entrainement et la source de courant de circuit de commande.

Abstract: A fire-safe seal for use in a swivel joint in a pressurized fluid subject to fire risk, the seal having both a metal anti-extrusion ring (23, 23a, 23b, 23c, 23d, 23e) and an annular resilient non-metallic seal member (22, 22a, 22b, 22c, 48) to provide essentially zero fluid linkage at normal operating temperatures, and the anti-extrusion ring to provide an extremely low rate of leakage in the event high temperature should destroy the resilient seal member. A curved spring (34) or other metal anti- cocking device (41, 41a, 41b, 47) biases the anti-extrusion ring tightly against the junction of a male (10) and a female (11) joint to ensure that the ring remains in position after the resilient seal member is destroyed to prevent leakage through the junction.

Abstract: A cylinder lock includes two barrels (23, 37), a first (23) carrying tumblers (30) that abut internal shoulders (36) of the lock casing (2) to obstruct clockwise «unlocking» rotation only, and the second (37) carrying a single tumbler (43) which obstructs only counter-clockwise «locking» rotation by abutment with a shoulder (48) of a rear-end casing-cover (8). A key (5) inserted through a keyhole-defining assembly (11, 16, 21) withdraws the first-barrel tumblers (30) during initial clockwise turning from the insertion position, and the second-barrel tumbler (43) during initial counter-clockwise turning. Lost-motion coupling between the barrels (23, 37), provided by lug-in-slot (38, 39) interengagement, enables clockwise turning of the second barrel (37) with the key (5) relative to the first barrel (23) during withdrawal of the first-barrel tumblers (30), and corresponding counter-clockwise turning of the first barrel (23) relative to the second (37) during withdrawal of the second-barrel tumbler (43). Lug-in-slot coupling (22, 24) between the keyhole-defining assembly (11, 16, 21) and the first barrel (23) similarly allows initial slip for clockwise key-turning. A coiled spring (42) opposes resiliently turning of both barrels (23, 37) in both directions.

Abstract: An inspection device detects flooding in a hollow structural member such as the leg of an oil or gas rig so as to detect the presence of through wall cracks in the member. The device comprises an ultrasonic transducer 19 for transmitting a pulsed beam of ultrasonic sound to pass through opposing faced walls or wall portions of the member and a visual indicator 32 responsive to time spaced echoes of the ultrasonic beam reflected respectively from the opposing walls or wall portions and received by the transducer 19 to indicate the presence or absence of flooding in the member. The transducer 19 is located in the bridge plate 10 of a jig and its beam passes through an aperture in a support frame 8 of the jig. The support frame 8 has a pair of spaced magnetic feet 16 attached to a bracket 15 on the frame 8 and a further magnetic foot 17 secured to the frame 8, the feet permitting the jig to be clamped onto a steel rig member so that the transducer can be optimally aligned with the member to optimise received echoes. 
     The bridge plate 10 is movable in two orthogonal planes by adjusting control knobs 12 and 13 so as to optimise alignment. A further visual indicator 31 also responsive to the echoes from the transducer 19 is adjustable to indicate whether the transducer 19 is optimally aligned and only when the transducer 19 is optimally aligned is the presence of flooding, if indicated by indicator 32, taken to be valid.

Abstract: A method of continuous hose manufacture in which hose comprising a liner 2, reinforcement 5 and cover 7 is cured by passage through a generally horizontal straight curing tube 8 containing a curing medium at a pressure and temperature sufficient to cure the hose. The curing medium acts directly on the outer surface of the hose and has a specific gravity substantially equal to that of the hose assembly passing through the tube 8 so that the latter is essentially supported by its buoyancy in the curing medium. The method enables hose to be produced in which curing is effected with the hose in a substantially straight configuration and subject to small, e.g. of the order of 10-100 Kg, haul-off tensions so that displacement of the reinforcement structure from its optimum configuration is minimised.
