Title: Flux exempt d'halogenes pour le brasage a base de colophane
Inventor: KERNER RUDOLF A
IPC: B23K35/36
Filed: 1980-12-15
Abstract: Le flux sans halogenes sert au b rasage a base de colophane, en particulier dans la production d'elements electroniques. Le flux a deux versions de base. La version (1) est un flux liquide a base de colophane dans laquelle on utilise comme solvant l'eau et les alkanols miscibles a l'eau et comme activateur la diethanolamine et les acides dicarboxyliques satures et insatures. Le flux est approprie pour l'application par mousses, trempage ou pulverisation pour le brasage, la trempe ou la soudure par vibrations. La version (2) est un flux solide, a base de colophane, dans laquelle on utilise comme ramollisseur les acides monocarboxyliques aliphatiques satures et comme activateur, la diethanolamine et des acides dicarboxyliques satures et insatures. La version (2) convient pour le remplissage ou le revetement de fils de brasage, de pieces moulees de rasage, de pates de brasage, etc... Les avantages de ce flux exempt d'halogenes sont une reduction importante de la tension superficielle de brasage, une diminution des ponts de brasage. Les flux exempts d'halogenes permettent le brasage du laiton, de l'acier et du nickel, atteignent lors de brasages manuels une vitesse d'ecoulement semblable a celle obtenue avec la plupart des flux avec halogenes et permettent d'obtenir une augmentation importante de la resistance superficielle avec une separation aisee et simple des dechets.

Abstract: A horizontal transporting trough (17) which incorporates a screw which transports the coal delivered at one end of the transporting trough to a vertical discharge situated at the other end. In the case of charging cars which can be moved across the roof of coke furnaces, the transporting trough is particularly suitable for transporting the coal dropping out of the car containers to telescopic tubes mounted on the furnace roof above the charging holes of the furnace chambers.   To prevent the coal forming lumps in the spaces situated outside the helix of the transporting screw, a screen (25) surrounding the helix of the screw is incorporated at the inlet opening of the trough. A guide vane (26) which is inclined at an angle to the transport direction and which shaves off any coal still adhering to the wall of the trough can be provided above the outlet of the trough. The base of the trough which conforms to the shape of the helix can drop away at an angle after the outlet. <IMAGE>

Abstract: Crude liquid polyether-polyols containing an alkaline catalyst are purified by the steps of:
     neutralizing said crude liquid polyether-polyol with a mineral acid having a dissociation constant of greater than 10- 3  at 25°C,   distilling off water from said liquid, and filtering the same. The improvement resides in the step of adding a hydrate of a metal salt of said mineral acid to the liquid polyether-polyol at a stage before the distillation step for promoting the crystal growth of a salt formed from said alkaline catalyst by the neutralization.

Abstract: A composition designed for dissolution or dispersion in water to give an aqueous treatment fluid which is compatible with cement slurries and with drilling muds and a method of using same to displace a drilling mud from a borehole which penetrates a subterranean formation. The composition comprises three components, a water soluble viscosifier which increases the viscosity of water under mixing and handling conditions but which becomes substantially insoluble in water when exposed to temperatures encountered downhole in a wellbore; a second component, a thickener, which is soluble or dispersible in and which increases the viscosity of water at temperatures experienced under downhole conditions; and a third component, a dispersant, which enhances the dispersibility of the first component in water and thereby permits it to go smoothly into solution. The resultant aqueous treatment fluid, at a temperature between 85° and 160°F, has a kinematic viscosity of greater than 0.1 and less than 7.5 centipoise-gallons. pound

The hour wheel (31) and the center wheel (29) present coaxial pipes which pass through the dial and bear hour and minute hands. These wheels are driven by a wheel-train (30, 28, 27) actuated by the stepping motor (25) which receives its pulses from the circuit (23) controlled at a frequency of 1 Hz for example by the quartz (48). The 24-hour wheel (33) bears a contact element (46) which, once per revolution, grounds the terminal (47). The pulse which results therefrom is transmitted to a counter incorporated in the circuit (23). This counter controls the decoding circuit which controls the display cell (21). To effect the setting of the date, the stem (35) is brought into its intermediate position (II). The contact element (40) borne by the yoke (38) then grounds the terminal (41), which causes in the circuit (23) the emission of pulses at a frequency of 1 Hz which controls a repeated and rapid change of date.

Abstract: La stabilisation en tension des sorties supplémentaires de convertisseurs est réalisée avec grande précision par un circuit de réglage dans lequel un courant traverse une capacité de stockage (26) et l'enroulement primaire (32) d'un transformateur (72). L'enroulement secondaire (33) de ce transformateur (72) est couplé par l'une de ses extrémités et à travers une diode (34) à l'enroulement primaire et par une autre diode (35) et un élément de commutation (36) avec son autre extrémité.

Lorsque la tension de sortie est en dessous de la valeur prescrite l'élément (36) est court-circuité et la valeur de la tension sur la capacité (26) est maximale. Si la valeur de la tension est égale ou supérieure, l'élément de commutation (36) devient non-conducteur et le courant induit dans l'enroulement secondaire (33) réduit le courant qui s'écoule de l'enroulement (8) du transformateur vers la capacité (26) dans la mesure du rapport inverse de la relation qui existe entre l'enroulement primaire (32) et l'enroulement secondaire (33).
