Patent EP-0341792-A1 (EP)
Inventor: LEHMANN RAINER DR
IPC: C02F9/00
Filed: 1989-05-08
Abstract: A process for treating spent pickling baths is described, which are obtained in the surface treatment of metallic materials, especially stainless steels. In this process, the spent pickling baths are neutralised on the one hand with NH3 and on the other hand with NaOH, NaHCO3 or Na2CO3, an Na/F molar ratio from 0.5 : 1 to 1 : 1 having to be adjusted. The metal hydroxides are then filtered off and the metal cations still present in solution are separated off by a cation exchanger. The fluoride is then precipitated as Na3AlF6 and filtered off. Finally, the water content of the solution containing NH4NO3 is reduced by evaporation at least up to an NH4NO3 content of 60% by weight.

Abstract: A moveable shield and associated liquid containment system which may be used with machines in which arrays of individual streams of liquid dye are used to pattern substrates. The shield associated with a given array selectively may be interposed between the substrate and the liquid dye streams of that array to prevent substrate contact by the liquid streams as, for example, during cleaning operations, or withdrawn to permit unimpeded substrate contact by the liquid dye stream. One or more arrays may be cleaned or charged with a different color dyestuff while the remaining arrays are used to pattern the substrate, eliminating the down time presently associated with the cleaning or dye changing of individual arrays.

Abstract: A needle threader (10) for needlecraft needles (25) has a notch (22,22A,34,45,46) to retain a needle (25) in position on the threader while thread is passed through the eye in the needle threader. The notch (22,22A,34,45,46) may be used in conjunction with shoulders (14,15) utilized as stops for the needle, or may be used with the more conventional threader. The notch (22,22A,34,45,46) for retaining the needle allows easier threading because the threader with the needle can be held with one hand while the thread is manipulated with the other.

Abstract: The machine applies to such machines having an endless moving screening mesh (5) to separate sand from foreign matter, a sand collecting ramp (4) and sand beat­ing device (3) at the input end of the screen, and a for­eign matter collecting and dumping hopper (9) at the out­let end of the said screen (5). The action of the beating device (3) is completed by a second beating mechanism (10); a flexible cover (13) placed over the screen (5) prevents bouncing of the foreign matter. Vibrating devices are formed of a shaft (14) with revolving blades (15) which strike the screen mesh (5). The hopper (9) is mounted oscillating at the free end of a articulated polygon articulated to an upper portion (16) of the machine frame (1). 
     It is thereby attained that the stones roll over the screening mesh (5), and the moist, soggy sand is broken up, thus enhancing screening of the sand. Also, the overall height of the elevating mechanism of the hopper (9) is lowered, thus increasing maneuverability.

Abstract: Selon un procédé de régulation lambda, on utilise deux circuits de réglage pour des blocs-cylindres différents. Une régulation par plus ou moins est effectuée par chaque circuit de réglage, ce qui produit une oscillation par circuit. Le déphasage entre les deux oscillations est déterminé et réglé de façon à correspondre à une valeurprédéterminée. Lorsque la valeur prédéterminée du déphasage correspond à une demi-période d'oscillation, les gaz d'échappement d'un bloc-cylindres passent de riche à pauvre dès que les gaz d'échappement de l'autre bloc-cylindres passent de pauvre à riche, et vice-versa. Lorsque les deux gaz d'échappement sont mélangés avant de parvenir à un catalyseur, celui-ci reçoit un mélange gazeux dont la valeur lambda est essentiellement égale à 1. Ce procédé permet ainsi d'obtenir une amplitude d'oscillation de la valeur lambda des gaz d'échappement inférieure aux amplitudes d'oscillation des valeurs lambda du mélange d'air/carburant amené aux deux blocs-cylindres; il s'ensuit une conversion améliorée des polluants. Un dispositif d'application du procédé comprend deux éléments de régulation par plus ou moins, un élément pour déterminer le déphasage réel et un élément de réglage du déphasage voulu.

Abstract: Le procédé de taillage de diamants décrit, dans lequel des lignes de guidage tracées sur la surface extérieure d'un diamant brut sont utilisées pour tailler jusqu'à six formes pyramidales (340) constituant des fragments provenant d'une pièce particulière de diamant (pouvant être taillé) en forme de tétrahèdre, permet de tirer le poids maximum d'un diamant taillé à facettes à coupe ronde poli (ou de tout autre diamant taillé à coupe ronde) obtenu à partir d'un diamant brut particulier, conjointement avec les fragments. Un crayon de marquage ou équivalent est maintenu parallèle à la ligne médiane du diamant (300) et est ajusté jusqu'à ce que sa pointe (330) touche la face la plus courte du diamant. Après mise en rotation du diamant par rapport à la pointe, on trace un cercle qui représente le diamètre rond maximum qu'on peut obtenir en taillant ce diamant. Le crayon traverse les arêtes (412, 414, 416, 418) du diamant et ces points de croisement définissent le point de départ de l'opération de taillage. Dans une variante améliorée, le crayon de marquage et sa pointe peuvent également être utilisés pour tracer la hauteur maximum du diamant façonné, les marques étant placées sur les arêtes, et une forme pyramidale peut être taillée depuis le sommet et/ou le fond (culasse) du diamant brut. Un laser est de préférence utilisé à la fois pour marquer et pour tailler le diamant en une seule opération, ce qui permet de réaliser des économies de temps et d'éliminer le besoin éventuel de réajustage ou de reréglage du diamant sur sa fixation.

Abstract: An apparatus for removing a soft stopper such as a cork from a container such as a bottle. The apparatus includes a hollow cylinder (120) having one or more slits (140) along its length and a handle (110) attached to the top of the cylinder. The interior surface of the cylinder includes one or more spiral wound threads (261) having a flat upper surface. The cylinder is inserted between the outer circumference of the cork and the interior wall of the bottle and is rotated so that the threads are embedded in the outer wall of the cork and serve to compress the cork inwardly as the apparatus is screwed into the container. A stop ring (150) serves to limit the penetration of the apparatus into the bottle and when the apparatus has reached its maximum penetration, the apparatus begins to force the cork out of the bottle as the turning motion of the cork continues. Various embellishments serve to enhance the efficiency of operation of the device.

Abstract: To make it possible to introduce slivers (F) between two rollers more effectively, on the driven roller (2) there is a spacing and driving ring (4) which has a height corresponding to the spacing (A). Moreover, this spacing (A) is provided in such a way that it is smaller than the smallest sliver thickness (D in Figure 2), in order to guarantee a compression of the sliver (F) between the rollers to the predetermined extent. The advantage is that, on the one hand, the sliver can be grasped better by means of the nip having the spacing (A), secondly the drag roller (3) rotates at a predetermined rate of rotation as early as when the sliver (F) is being introduced, and furthermore the ambient air of the rotating rollers (2) and (3) can be guided through the nip, thus assisting the drawing in of the sliver. The drag roller (3) is held movably, as represented by the directions of the arrows (Y) in Figure (2). <IMAGE>

Abstract: A carbon dioxide (CO₂) waveguide laser (10) to provide coherent infrared radiation contains a mixture (20) of gases that includes helium, nitrogen, carbon dioxide, carbon monoxide, xenon and heavy hydrogen (deuterium). Carbon dioxide is the gain medium of the laser. During operation of the laser, a significant fraction of the CO₂ dissociates to CO and O₂. Deuterium (D₂) in the presence of excess CO catalyzes the recombinhation of CO and O₂ back to CO₂, thus yielding significantly increased power output from the laser. The presence of D₂ also sustains a long sealed life from the CO₂ laser at an enhanced power output level.
