Title: Procede de fabrication de doublure de conduit a partir d'un tuyau inverse sans excavation
Inventor: IMAMURA MINORU
IPC: F16L55/165
Filed: 1990-09-04
Abstract: Procédé de fabrication selon laquelle on revêt l'intérieur d'un conduit d'alimentation d'eau ou de gaz mis sous la terre d'un tube que l'on fait avancer dans ledit conduit pendant qu'une pression fluide l'inverse. Tout le processus de revêtement s'effectue sur une partie du conduit qui se trouve au-dessus de la terre. On mesure d'abord à travers le conduit une distance de l'entrée du conduit jusqu'au raccordement en T, un tube qui a été coupé à une longueur légèrement plus longue que la longueur ainsi obtenue y étant inversé. Une partie courte non inversée du tube reste donc dans le conduit du côté de l'extrémité avant dudit tube. La partie non inversée peut être utilisée lorsqu'une bande de déroulement attachée audit tube est coupée par un dispositif de coupe introduit dans le conduit. Après l'inversion du tube de doublure, on procède de la manière avec un tube de chauffage. Un tuyau à eau chaude pour la circulation interne d'eau chaude est introduit dans le tube de chauffage de sorte que le conduit est doublé à l'intérieur par ledit tube de doublure, sur lequel on a étalé un adhésif thermodurcissable. Lorsqu'on a achevé la doublure interne, on retire d'abord le tuyau à eau chaude, et ensuite le tube de chauffage à l'aide de la bande de déroulement, la bande de déroulement du tube de doublure étant coupée afin de la récupérer. La dernière étape comprend l'introduction d'une tête de fusion dans le conduit de manière à ouvrir par fusion le bout du tube de doublure pour le passage du fluide. Ladite tête de fusion est ensuite retirée, ce qui achève le processus de doublure.

Abstract: A wheel truck (10) for an aircraft landing gear carries a plurality of wheel sets (16,18,20,22), each set having a left-hand wheel and a right-hand wheel. The wheels of any given set are free to rotate about a longitudinal axis (58,60) so that they will follow transverse ground contours as the aircraft taxis. Each wheel set, as a whole, can also pivot about a transverse axis (28,30), in order to adaptively follow longitudinal ground contours. The pivotable mounting arrangement of the wheels to the truck (10) enables all wheels to maintain an equal force contact with the ground, so that one wheel will not be overloaded relative to another.

Abstract: A breathing demand regulator for use in aircrew life support apparatus has an aneroid capsule 56 coacting with a valve head 50 to restrict outflow from a breathing pressure control chamber 32. The aneroid capsule expands to move the valve head in the event of aircraft cabin altitude rising above a predetermined level due to loss of cabin pressure. An end face 53 of a valve stem 51 supporting the valve head senses inflation pressure of an aircrew G-suit by way of a passageway 59 for movement of the valve head in the presence of G-load. This arrangement provides for increased control pressure and, hence, increased breathing gas pressure in a regulator outlet 13, in meeting the higher of requirements for positive pressure breathing to protect an aircrew member exposed to both G-load and high aircraft ambient altitude (say above 12000 metres). 
     The regulator is disclosed in combination with an anti-G valve arrangement 90, 100 and a G-suit inflation control valve arrangement 60, 61, and 120, 121 that provides the higher of G-suit inflation pressure requirement for protecting the aircrew member when exposed to high aircraft ambient altitude in the presence of G-load.

Abstract: An improved process for dehydrogenation of detergent range normal paraffins contained in a hydrocarbon mixture to produce monoolefins is described. Improvements are obtained by operating over an entire catalyst operating cycle at an average added hydrogen to detergent range hydrocarbon ratio of from about .5 to about 1.9. The improved process is operated in a substantially adiabatic, plug flow reactor at a suitable catalyst bed inlet temperature not greater than about 450°C. The process provides improved tolerance for initial excess catalyst bed activity, allowing desirable catalyst operating cycle lengths to be obtained with more favorable operating conditions.

Title: Moulded aromatic-polyester article.
Inventor: FIALLA PETER
IPC: B29C43/00
Filed: 1991-07-26
Abstract: Disclosed are translucent, pore-free, sintered aromatic-polyester articles manufactured from diphenols, such as 1,1-bis(4-hydroxy phenyl) fluor and from phtalic acid halides, the sintered articles having one or more glass transition points in the range between 220 and 400 DEG C and a tensile strength greater than 40 N/mm<2>, preferably however greater than 60 N/mm<2>. They have greater resistance to certain solvents such as carbon tetrachloride than cast films made of the same material. Such sintered articles are manufactured by subjecting polyester powder in a closed mould to a pressure of more than 3000 N/cm<2> while slowly heating the mould, holding the mould for a relatively long time at a temperature above the glass transition point and subsequently cooling it again slowly. Sintered articles produced in this way are mainly of use as semi-finished products or moulded component blanks from which the required finished product can be produced by machining.
