Abstract: A recycling process for zinc-rich solid waste containing zinc oxide, Cu oxides and impurities normally present in brass, in which a mixture is formed containing the waste with a finely divided solid reducing agent and a binder, and the mixture is compacted as agglomerates with open pores. The agglomerates are added into a treatment reactor containing a bath of liquid copper or brass metal, in which the zinc and copper oxides are reduced, to obtain in the treatment reactor after the reduction, a new brass in liquid form and a new waste. The new liquid brass is transferred into a fusion and casting furnace, in which its composition is optionally adjusted, and the new liquid brass is cast to form a product. Any waste present in the treatment reactor and the casting furnace are recycled using this process.

Abstract: The present invention relates to a flow control system for sprayer nozzles. The control system includes a solenoid coil and a solenoid plunger. The solenoid plunger can slide into an adapter body, substantially perpendicular to the direction of fluid flow. In reducing the fluid flow through the nozzle, the plunger is moved to block an orifice in the path of the fluid flow, within the adapter. The plunger movement is achieved through the energization of the solenoid coil, with signals sent by a controller. The orifice in the adapter is manufactured to a specific size which allows reduced power consumption to shut off or reduce flow through the nozzle. Also, the orifice is sized to provide unrestricted flow when fully open. By means of the controller, control can be provided individually to each nozzle from a plurality of nozzles on a spraying bar. In one aspect of the invention, the flow control system can be used on agricultural sprayers with sensing equipment such as cameras that may determine the green condition of the foliage being sprayed. According to the determined condition, the controller would regulate the flow through the nozzles in the corresponding area of the field. The control valve adapts to industry standard fittings and adapts to a position on the fittings so the spray fluid passes through the filter and nozzle check valve before passing through the control valve while the nozzle check valve remains in place. Specifically, the control valve can be adapted onto a standard fitting and inserted between the nozzle screen and spray tip.

Title: Method for preparing water-soluble cross-linked conjugates
Inventor: LIHME ALLAN OTTO FOG
IPC: C12Q1/68
Filed: 1999-07-29
Granted: 2011-06-28
Abstract: The preparation of new water-soluble cross-linked conjugates and cross-linked conjugate complexes improves the detection ability of immunochemical assays, including lateral flow devices, and relies on a "salting-out" process in which a reversible precipitate is formed at lyotropic salt concentrations greater than 1 M and coincides with a cross-linking of the backbone of the water-soluble intermediate conjugate. The backbone, which consists of polysaccharides, including dextrans, is linked to a signal component, such as a dye, that produces a colour, via a bifunctional linker component, such as epichlorohydrin or divinyl sulfone, and optionally through a protein spacer component such as ovalbumin (OA) or bovine serum albumin (BSA). The cross-linking of the dextrans occurs via the linker component, during the "salting-out" process to give, in the presence of suitable targets such as antibodies or antigens, water-soluble cross-linked conjugates and cross-linked conjugate complexes.

Abstract: Selon l'invention, un système de karaoké mobile combine un signal provenant de l'audio externe (tel que la voix du chanteur interprétant une chanson dans un microphone) avec les données sur l'accompagnement musical de la chanson qui sont enregistrées en mémoire (essentiellement les données stockées dans une ROM) et émet le signal destiné à être transmis par un émetteur. L'invention est caractérisée en ce que suit: l'émetteur mobile sans fil pour le système karaoké est pourvu d'un décodeur supplémentaire, qui interagit avec une cartouche au moyen d'un bus d'interface; la cartouche est munie d'un dispositif d'identification et de codage à clés, couplé à la ROM et pouvant interagir avec le décodeur supplémentaire de l'émetteur à travers le bus d'interface. Le signal utilisé dans la transmission à destination du récepteur peut être un signal optique, un signal acoustique par ultrasons, un signal radiofréquence transmis par un champ électrique et/ou magnétique du champ proche de l'antenne lors de la suppression de la radiodiffusion; en variante, on peut utiliser la radiodiffusion sur une gamme de fréquences librement attribuée, avec transformation de ce signal sur le lieu de réception en une fréquence de la gamme de radiodiffusion et réception subséquente par un poste radio conventionnel. L'invention permet d'empêcher, d'une part, tout accès non autorisé aux données stockées dans la ROM de la cartouche et, d'autre part, toute utilisation dans le système karaoké de cartouches non autorisées (piratées), ce qui permet d'assurer le respect des droits d'auteur des auteurs de pièces de musique et des détenteurs légitimes de droits de propriété intellectuelle.

Abstract: An electrical connector for interconnecting a portable radio and accessory devices. The connector attached to the accessory device includes a slot for initially engaging a tab on the portable radio, which provides proper alignment between the portable radio and the connector, while the connector is rotated toward the portable radio. Maintaining alignment ensures proper mating between the electrical contacts of the portable radio and the electrical contacts of the connector, and further ensures that a quarter turn latching device of the connector is properly received by a receiving member on the portable radio. The user then rotates the quarter turn latching device to urge the contacts against each other and secure the connector in place. Because the electrical connector includes a two-point attachment mechanism to the portable radio, rotation of the connector relative to the portable radio is prevented.
