Abstract: La présente invention se rapporte à un dispositif et à un procédé de brasage tendre à la vague de circuits imprimés, en particulier de soudage de composants appropriés pour le montage en surface. Comme l'indiquent les revendications de la présente invention, la vague de brasage - ou une partie de celle-ci - est formée par des écoulements de brasure fondus progressant dans une direction orbitale. Ces écoulements peuvent progresser horizontalement (0) dans un sens qui se déplace cycliquement entre 0 et 360°, permettant ainsi l'élimination des bulles de gaz/d'air - éventuellement piégées à proximité d'un composant (11) - quel que soit la position dans laquelle elles stagnent. Tout défaut de soudage dû à un soudage ''sec'' est ainsi évité.

Abstract: Comprises a framing constituted by two parts coupled to each other and consisting in each of its halves of a rectangular frame having a cross bar (32, 33) and a pair of angular supporting legs (5, 6), effecting a connection of the parts by the longitudinal bars, and one of the parts forming a head portion defined by an inclination of the end portion of each of its longitudinal bars. The coupling of the two halves of the framing is effected by means of an insert element (9) protruding from the end of each half-portion of the longitudinal bars and the tubular termination of the end of the corresponding half-portion of the longitudinal bars of the other part. The longitudinal bars of the frame have linear and parallel edges adapted for the connection of curved transverse slat members (13) thereto functioning as supports. The sides of the frame have a plurality of openings (14) for the insertion of elastic holding cords of a rectangular piece of resistant cloth which is permanently tensioned. The structure of the framing is reinforced by an internal armature in form of a rectangular U, and the angular supporting legs comprise wear resistant protective garnishments (15) in the zones engaging ground. An inclineable and removable back-rest (16) constituted by a support in form of a rectangular U is pivotally coupled by its ends (17, 18) to the longitudinal bars of the framing and comprise means (22) for fixing the desired inclination.

Abstract: In the case of an injection moulding method for making hollow plastic objects, in which a fluid is forced into the mould under pressure immediately after injecting the plastic polymer melt, so that the polymer melt spreads out over the surface of the mould cavity, the fluid is forced into the mould cavity through an injection sleeve, which is in the inner sprue region of the moulding and is surrounded by flowing plastic polymer melt, so that the forced-in fluid reaches the mould cavity without first coming into contact with the plastic polymer melt. The apparatus for making such plastic objects has an injection sleeve, provided at a distance in the inner sprue region of the moulding, for the fluid feed into the plastic polymer melt injected into the mould cavity, which sleeve controls the direction of the flowing-out fluid in such a way that it coincides with the direction of melt thrust in the mould cavity. <IMAGE>

Abstract: Vapor phase catalytic hydrogenation of maleic anhydride to gamma-butyrolactone is achieved in a conversion of 95% or more and a selectivity of 80% or more during a prolonged period of production. The process uses an activated catalyst prepared by reducing a catalyst composition comprising 30-65% by weight of CuO, 18-50% by weight of ZnO and 8-22% by weight of Al2O3, and activating the reduced catalyst composition in hydrogen at an activation temperature of at least 400 DEG  C., preferably 400 DEG  to 525 DEG  C., and optimally about 425 DEG  C. The process suitably is carried out under predetermined and advantageous process conditions, including a defined molar ratio of hydrogen to maleic anhydride in the vapor reactant stream, a selected pressure during hydrogenation, a defined feed rate space velocity, a predetermined contact time, and a suitable reaction temperature.
