IPC: F16J15/34
Filed: 1990-10-26
Abstract: A seal system for sealing a housing (12) and rotatable shaft (16) against leakage of a gas under high pressure; hydrogen is an example. The system, using multiple seals in tandem, provides a stepped reduction of high pressure gas at full height pressure to a low pressure across the individual seal modules. 
     The seal system has plural, axially spaced spiral-­grooved end face seal modules (20, 22, 24) mounted between the shaft (16) and housing (12), the axial spaces between the seals defining a chamber (12, 21, 23). Each seal module (20, 22, 24) has a primary seal ring (26a, 26b, (26c) affixed to the housing (12) and a mating ring (30a, 30b, 30c) affixed for rotation with the shaft (16), the two rings (26, 30) having opposed, radially extending faces (32, 28); each mating ring (30) has a plurality of radial spiral grooves (92) extending radially inward from the outer diameter or circumference.

Abstract: Condenser fluid, comprising vaporized working fluid and non-condensable gases, is treated by extracting fluid from the condenser (16A) and pressuring the fluid to liquefy the vaporized working fluid therein in such a way that the non-condensable gases are separated from the working fluid and can be vented from the extracted fluid. A piston (36) draws the vaporized fluid into a chamber (32) through an open valve (33). The valve is then closed and the fluid is compressed by the piston (36), the fluid being cooled by a cooling coil (53), so that working fluid condenses, whereupon the non-condensed gases are vented (valve 39). The valve (33) is then opened so that the working fluid can flow back into the condenser (16A).

Abstract: A method of evaluating properties of an oxygen sensor used for detecting air-fuel ratio of exhaust gas from internal combustion engine comprises steps of preparing a burnt gas having a predetermined excess air ratio, supplying additional oxidation gas and/or reduction gas into the burnt gas, and detecting an output from the sensor exposed to the mixed gas flow. The supply amount of the additional gas is increased and decreased with a frequency of at least 10 Hz, and a ratio of a supply increasing period to a supply decreasing period is changed to change the supply amount of the additional gas, so that an excess air ratio λ can be controlled similarly to exhaust gas from an actual engine.

Abstract: A method of passivating etched mirror facets of semiconductor laser diodes for enhancing device reliability. 
     The etched mirror facet is first subjected to a wet-etch process to substantially remove any native oxide as well as any surface layer which may have been mechanically damaged during the preceding mirror etch process. Then, a passivation pre-treatment is applied whereby any residual oxygen is removed and a sub-monolayer is formed which permanently reduces the non-radiative recombination of minority carriers at the mirror facet. Finally, the pre-treated mirror surface is coated with a passivation layer to avoid any environmental effect on the mirror.

Title: Internally delaminating tabbed innerseal for a container and method of applying.
Inventor: MCCARTHY THERESA A
IPC: B65D53/04
Filed: 1990-01-17
Abstract: An improved innerseal for sealing containers includes a body portion having an upper surface and structure connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure adapted for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding portion which is adhered to the first bonding portion with a second bonding force which is less than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and remain adhered to the rim, while a second part of the first bonding portion will remain adhered to the second bonding portion, thereby exposing the opening in the container when the grasping structure is pulled. A method for manufacturing containers so sealed is also disclosed.

Abstract: Cette invention concerne un procédé d'adjonction d'une substance malodorante dans un gaz utilisé par des consommateurs, tel que de l'oxygène, du gaz naturel, du gaz propane, du gaz de ville ou tout autre gaz combustible, qui n'a pas d'odeur et qui est toxique, ou bien à un gaz plus ou moins inerte alimentant un point de consommation. L'adjonction de cette substance malodorante permet d'avertir les personnes se trouvant à proximité du point de consommation qu'il existe un risque d'incendie, d'explosion, d'asphyxie, de toxicité ou un autre risque lié à la présence d'un gaz de consommation dans l'atmosphère environnante, et ce, en raison d'une fuite, d'une négligence ou pour toute autre raison. Ce procédé comprend le mélange d'un gaz principal, par exemple, un gaz porteur dilué avec la substance malodorante, avec le gaz de consommation. Le trait caractéristique de ce procédé réside dans la dissolution de la substance molodorante qui se présente sous forme d'un composé de soufre organique ou d'un mélange de deux ou plusieurs composés de soufre organique, ces composés comprenant du tétrahydrothiophène, du mercaptan de méthyle, du mercaptan d'éthyle, du mercaptan de propyle et du mercaptan de butyle, du sulfure de diméthyle, du sulfure de diéthyle et du sulfure de méthyléthyle, dans du dioxyde de carbone condensé, de l'hexafluorure de soufre ou de l'oxyde nitreux dans un récipient de pression, qui produisent dans ce dernier une phase liquide, constituée d'une solution de substance malodorante dans le gaz condensé, et une phase gazeuse; on élimine ensuite la phase liquide du récipient, par vaporisation, et on ajoute la phase vapeur résultante dans le gaz de consommation, qui est alors distribué aux consommateurs. Cette invention concerne également un mélange gazeux comprenant la substance malodorante sous forme de dioxyde de carbone, d'hexafluorure de soufre ou d'oxyde nitreux condensés.

Abstract: A variable displacement, rotary fluid pressure pump (11) is disclosed of the type having a cam ring member (25) which is movable, in response to rotation of a control shaft (35), between a neutral position (FIG. 5) and a displaced position (FIG. 4). The pump housing (13,15) includes a support member (25), and they cooperate to define a high-pressure fluid passage (51). In communication with the passage (51) is a recess (71), in which is disposed a dampening shoe (73). The dampening shoe is biased by high-pressure fluid in the passage (51) into engagement with an adjacent surface (77) of the cam ring (25). The surface (77) defines a neutral fluid passage (79), and the dampening shoe (73) defines a restricted opening (85). When the cam ring (25) is in the displaced position, the restricted opening (85) is blocked from communication with the neutral passage (79), but as the cam ring is returned to its neutral position, the opening (85) begins to communicate with the neutral passage (79), thus providing the pump with an increased neutral band overlap.

Abstract: The built-up anti-backflow and anti-leakage injection nozzle comprises a structural nut (2), a valve casing (16) and a nozzle tip (11) which are screwed into one structural member. The valve casing (16), which is of a hollow structure, houses a compressed biasing spring (8) which acts toward the nut side on an anti-backflow valve (4) (first sealing point) and toward the tip side on an anti-leakage valve (10) (second sealing point), such that moving of the molten plastic materials is controlled by the two respective sealing points (3, 12). During injection the high-pressure molten materials force open the above-mentioned two sealings simultaneously. When injection has stopped, biased by the spring (8) the two sealing points are sealed simultaneously. In this manner, both backflow and leakage of the molten materials can be well prevented, and the quality of the moulded products can be greatly increased.
