IPC: F16K17/04
Filed: 1986-12-22
Granted: 1990-09-05
Abstract: In a poppet check valve (10), a cylindrical inlet passage (46) connects axially with a valve chamber (56) and a shoulder (50) at the juncture between the inlet passage and the chamber defining an annular valve seat (54). A relatively thin disc-like valve element (60) in the valve chamber (56) has a generally circular imperforate central section (66) of a diameter greater than the diameter of the inlet opening (52) but less than the diameter of the valve chamber (56). A pluarlity of legs (68) extend radially from the periphery of the central section (66) into sliding engagement with the inner wall (48) of the valve chamber (54). A circular seal element (72) is joined to one side of the central section (66) and is maintained under a bias toward the seat by a coil spring (62) mounted in the valve chamber (56). Between the spring (62) and the valve element (60) is a stop member (64) including a plurality of radially spaced, axially extending force applying elements (98) engaging the central section (66) of the valve element (60). The stop member (64) also includes a guide surface (95) radially outwardly of the force-applying elements (98) for sliding engagement with the wall (48) of the valve chamber (56) at a location axially spaced from the valve element (60).

Abstract: At transmission (10) each bit for transmission is coded as a function of its state by producing (12) a particular coding frequency combination, these being divided into two distinct bands spaced one from another and the coding combinations being chosen such that frequencies ranked in the same sequence place in these combinations do not occupy the same frequency band. A signal comprising the coding combination is injected to the network (N,P) and at reception (20), is applied to demodulators (22, 23), each assigned to one respective frequency band, to be correlated with locally generated signals (25, 26) which reproduce the coding combinations with a constant frequency shift, the bit state being determined (24) as a function of the correlation output.

Abstract: A cathode compartment is defined by a pair of filter walls between which a cathode or electrolyzing ionic solution of a metal is received. The electrolysis is forced through this compartment and the current density against an anode outside the compartment is sufficiently high to cause at least some of the metal in solution to deposit as a powder which accumulates in the cathode compartment and augments the effective surface area of the cathode.

Title: Appareil de detection de gas
IPC: G01N27/74
Filed: 1986-05-07
Granted: 1990-04-25
Abstract: L'appareil ci-décrit comprend une chambre à gaz (4) dans laquelle un corps d'essai (20) entouré par un conducteur électrique monospire est suspendu par une bande métallique dans un champ magnétique non uniforme et non symétrique qui est formulé par des pôles (5) de forme spéciale qui pourraient, dans un mode de réalisation, être des aimants permanents. Le corps d'essai est soumis à une déflexion par rapport à la position initiale qu'il prend lorsqu'un gaz de référence se trouve dans la cellule, déflexion due à l'admittance d'un mélange de gaz dont un gaz paramagnétique est un constituant. La déflexion est détectée par un système optique comportant une source lumineuse, un miroir sur le corps d'essai et une paire de cellules photoélectriques. Le signal de sortie produit par les cellules photoélectriques alimente un signal d'amplification, qui à son tour alimente l'enroulement monospire en un courant de valeur suffisante de sorte que celui-ci empêche le corps d'essai de se déplacer par rapport à sa position initiale et est donc proportionnel à la pression partielle du gaz paramagnétique dans l'échantillon. L'effet du gaz pénétrant dans la chambre et influant sur le corps d'essai est réduit au minimum par la configuration spéciale des orifices d'admission et de sortie du gaz, et de son cheminement à l'intérieur de la chambre. La cellule est rendue étanche au gaz par des joints hermétiques et mécaniques plutôt que par l'emploi d'adhésif.

Abstract: It has been found that layers which include arsenic and/or zinc can have an adverse effect upon optoelectronic semiconductor devices such as lasers. This is reduced by treatments in which arsenic and zinc are excluded. Preferably the substrate is cooled from reaction temperature in the presence of a mixture of hydrogen and PH3 (replacing AsH3 and/or Zn(CH3)2 used to grow the final layer). Alternatively, devices having a contact layer of heavily p-type gallium indium arsenide are improved by the deposition of a protective layer of indium phosphide. This layer is removed immediately before metalisation. Even though the protective layer is not present in the final product it has a beneficial effect.

Abstract: Flameproof electrical switch gear (1) has a busbar channel (2) and two or more pressure-proof housings (7) which are to be connected electrically to the busbar channel by means of plug-in devices. The pressure-proof housings (7) can be conveyed on a supporting device (10) by means of a positioning drive (11). A door (15), to be opened by vertical movement, of the pressure-proof housing (7) cannot be opened until the pressure-proof housing (7) has been conveyed sufficiently that the contact elements of the plug-in device (4) have been separated and the door (15) has been moved out of the region of effectiveness of an upper protection device (14). When the pressure- proof housing (7) is completely taken away, a push button (17) fitted to the socket part (5) of the plug-in device (4) is operated to disconnect a supplying switching unit and thus to ensure that the installation is no longer live. <IMAGE>

Abstract: In order to obtain coatings of greater density and compactness than were possible until now when coating substrates with magnetic field-supported cathode sputtering, a given fraction of metal vapor obtained by vaporization of an electric arc discharge from the anode or cathode is deposited on the functional areas of the substrates together with the sputtered material and, specifically, at least 5 atom percent of the total metal fraction of the coating to be deposited averaged over time is applied by vaporization of an electric arc discharge. A suitable vacuum coating installation for carrying out the method has within a vacuum chamber, a device for vaporizing a part of the coating-forming material with an electric arc discharge and an additional device for magnetic field-supported sputtering of another part of the coating-forming material.

Abstract: A bag (210) comprised of flaccid material and having an improved integrally formed carrying handle which supports the weight of one or more articles (5) contained within the bag with minimal discomfort to the supporting portion or portions of the user's body. The bag includes an uppermost flap (55) containing the improved integrally formed carrying handle.
