IPC: B23K1/008
Filed: 1992-09-23
Abstract: A soldering apparatus 20 includes a conveyor 22 adapted to carry assembled circuit boards through a soldering chamber 24. A wave 26 of solder is created in the chamber 24. The chamber 24 has a curtain 40 at its entrance 21 and a curtain 41 at its exit 23. Gas distributors 32 and 34 are located within the chamber 24 and are able to introduce nitrogen into the chamber 24 in order to create a non-oxidising atmosphere in the vicinity of the wave. In operation, the wave 26 of solder wets connecting points between the components and the board to form permanent joints on solidification of the solder. The bottom edge of the curtain is of a shape complementary to the front elevation of the assembled circuit boards to be soldered and is arranged such that the circuit boards just pass thereunder without making contact with it.

Abstract: The invention relates to a waggon (1) comprising, at one end, a movable ramp (2) which is lowered simultaneously with the buffers (8). The movable ramp (2) and the platform of the waggon (1) carry rails, on which the bogies (4) can roll. Arranged parallel to these rails are C-shaped slideways, in which are displaced chains, the ends of which carry hooks for gripping the bogie (4) and hauling it onto the ramp (2) and the platform (1). These chains and the hydraulic ramp-actuating jacks (2) receive the working fluid from a motor-driven pump unit (22) via the controls (23).

Abstract: The specification hereof discloses an adjustable regulator of the type having fluid coupling oil within a cavity exposed to ambient pressure and overlying a diaphragm which operates based upon imbalances of said ambient pressure and an intermediate pressure zone on the other side of said diaphragm. The adjustment of the spring on the diaphragm is accomplished by means of a cap screw which is screwed into the sidewalls of the regulator within the cavity holding the oil. The oil is prevented from draining from the cavity by a second diaphragm overlying the oil in the cavity which can flex based upon changes in ambient pressure. The cap screw has a threaded extension in the form of a stem and tool surface on the other side of said stem for turning said cap screw. The stem passes through the second diaphragm in a sealed manner to prevent flow of coupling fluid between the interface of the diaphragm and the stem while at the same time allowing for adjustment by turning the cap screw in its adjacent threads so that compression can be changed with regard to the spring thereby adjusting the entire regulator. A further improvement is a valve seat which deters delamination of the valving surface between the metal of the valve seat and the sealing material by the sealing medium extending into an intermediate pressure zone to help prevent delamination from the metal surface.

Abstract: Procédé de production d'imines et/ou d'amines aliphatiques à partir d'alcools aliphatiques monohydriques, tels que des oxo-alcools à poids moléculaire supérieur, y compris des alcools d'éther, comprenant les étapes suivantes: déshydrogénation de l'alcool en aldéhyde in situ en présence d'un catalyseur de déshydrogénation d'oxyde de zinc et/ou de sel ou d'hydroxyde de zinc et d'une quantité soluble d'une amine aliphatique primaire qui se condense immédiatement avec l'aldéhyde dans des conditions de reflux, avec une suppression continue de l'eau, pour produire l'imine aliphatique correspondante (base de Schiff). On peut produire l'amine aliphatique correspondante par réduction ou amination réductrice de l'imine de façon connue, pour former les amines primaires, secondaires ou tertiaires, au choix. L'étape de production de l'imine est très critique et on a découvert que le système de déshydrogénation avec catalyseur d'hydroxyde de zinc produit une conversion douce, économique et efficace de l'alcool en aldéhyde, réagissant avec l'addition graduelle d'amine primaire, associée à la suppression continue de l'eau de condensation, afin d'empêcher des réactions secondaires indésirables diminuant le rendement.

Abstract: A beam adapted for implantation within a bone is able to support bending and torsional loading forces applied thereto. The beam has a stiffness defined by a modulus elasticity, which stiffness varies along the length of the beam to match the corresponding stiffness of the cortical bone adjacent the beam after implantation within the bone. The beam is made from an elongated core formed of continuous filament carbon fibers embedded in a thermoplastic polymer matrix with the carbon filaments extending in a direction substantially parallel to the longitudinal axis of the beam. Encasing the core is a filler molded to the core, which filler is made up of the same thermoplastic polymer as the core but contains no reinforcing carbon fibers. The filler provides the prosthesis with a shape generally conforming to the desired shape of the final prosthetic implant. A sheath formed of carbon reinforced filament fibers embedded in the thermoplastic polymer is wound in spiral formation around the filler and molded thereto. The winding angle and the sheath thickness along the beam may be varied to vary the modulus of elasticity to match that of the cortical bone adjacent thereto.

Abstract: On décrit un polyanhydride de polyacide utilisé comme adjuvant de blanchiment notamment pour augmenter le pouvoir blanchissant à basse température des produits décolorants à base de peroxygène tel que l'eau oxygénée ou le perborate de sodium, dans des compositions pour lessive ou autres compositions détergentes. De préférence, on obtient les polyanhydrides à partir d'acides carboxyliques polybasiques, le plus souvent dibasiques, qui peuvent être de nature aliphatique et/ou aromatique. Le polyanhydride peut être un homopolymère ou copolymère et comporte en moyenne au moins deux unités de monomères par chaîne. De préférence, on obtient le polyanhydride en faisant réagir les acides dibasiques libres avec un excédent d'anhydride acétique et en les faisant refluer jusqu'à obtention du poids moléculaire désiré et en enlevant ensuite l'acide acétique formé et l'excédent d'anhydride acétique. Des exemples de polyanhydrides sont les polymères des acides sébacique, adipique, azélaïque, succinique, fumarique, iso- et per-phthalique et citrique. Les polyanhydrides sont des solides faciles à manipuler, reltivement stables lors du stockage et permettant d'accélérer l'opération de blanchiment.

Abstract: In a diversity antenna selection method for receiving AM-modulated television signals by means of at least two antennas, it is provided that the antenna signal voltage from the antennas is supplied via electronic change-over switches to a common receiver, the antennas being selected by a priority circuit as a function of particular signal criteria. A comparator in a measuring device is used for comparing the mean value or a particular set threshold value with the field strength difference measured during short keying periods. As a function of this, a control signal is generated for controlling the change-over switch for the antennas.

Abstract: The invention relates to a method of discharging flue gases (pure gases), purified by catalytic denitrification, dust removal and wet desulphurisation from a furnace installation, in particular a fossil fuel-operated power station, into the atmosphere, wherein the pure gases, saturated with water vapour, are fed, after they have left the flue gas desulphurisation plant (5), by a suction fan (6) to the stack (7) and are heated before they enter the stack (7). In order to reduce the cost of construction and utilities and to avoid the emission of highly corrosive coarse particles, the heating of the pure gases takes place during operation by exploiting the polytropic compression work of the suction fan (6). At the same time, the wall of the pure-gas duct (8) between the fan outlet and the stack outlet is electrically heated (9) to a temperature above the temperature of the pure gas. During the starting times and other phases with increased production of moisture, additional heating (11) of the pure gases is carried out before they enter the stack (7). <IMAGE>
