Abstract: A dispenser for cryogenic liquid comprising a vacuum insulated vessel (2) which is provided with a dispenser tube (10). The dispenser tube (10) is heated in use by an electric heater (11). Sufficient heat is supplied to achieve film boiling on the inner surface of the dispenser tube (10). Flow of cryogenic liquid from the vacuum insulated vessel (2) into the dispenser tube (10) is controlled by a tapered valve member (14) which is biased downwardly by a spring (15) and which is connected to a permanent magnet (16) disposed in a coil (17). The tapered valve member (14) can be driven upwardly or downwardly according to the sense in which a direct current is applied to the coil (17). A gas relief tube (18) is provided to vent gas from the dispenser tube (10) intermediate the tapered valve member (14) and the outlet of the dispenser tube (10). The gas relief tube (18) conveys gas to the space above the cryogenic liquid, for example liquid nitrogen, in the vacuum insulated vessel (2). The dispenser has particular utility in high speed canning and bottling lines.

Abstract: A drop-on-demand ink jet printhead (1) comprises a body formed with a series of parallel ink channels (16) with respective ink ejectors (18) formed in a row at corresponding channel ends and having means for ejecting ink drops from the channels. A housekeeping manifold (50) is fitted to the ejector ends of the channels (16) and affords a trench (53) extending parallel with the row of ejectors (18) through which the ejectors discharge drops. Openings in the trench connect (53) the trench with the manifold (50) and duct means (112,114) in the body serve for supplying environmental fluids to and exhausting such fluids from the region of the ejectors by way of the trench (53), the openings and the manifold (50).

Granted: 1993-04-01
Abstract: This unit (1) comprises a recipient (2) on which is mounted a distribution head (3). The latter comprises a rotating cover (16) which is maintained on the recipient (2), and whose operation causes the translation of an adapter (13) mounted in a sliding manner on the neck (5) of the bottle. It is thus possible to open and close an upstream valve whose moving part is a plate (18) of the said adapter (13) and whose seat (37) is carried by the cover (16). The plate (18) serves as a support for a spring (14) drawing an applicator (15) into a position of closure of a downstream valve whose seat is carried by the cover (16). The downstream valve opens by the pushing in of the protruding end-piece (49) of the said applicator (15) when it is placed on the support intended to receiver the substance. The position in which the upstream valve is open corresponds to the "ready to use" position, the downstream valve still being closed. The position in which the upstream valve is closed blocks the downstream valve and ensures perfect fluid-tightness. <IMAGE>

Abstract: The present invention relates to spinnable and mouldable polyamide-imide solutions as well as the process for their preparation. They contain 4 to 35% of a polyamide-imide having a polydispersity index</=2.1 in a solvent mixture containing 45-100% by weight of DMEU and 0-55% of an aprotic polar solvent. They are obtained by the reaction, in dimethylethyleneurea of pH</=7 as polycondensation solvent, of a diisocyanate, an aromatic acid anhydride, optionally an alkali or alkaline earth dicarboxybenzene sulphonate and optionally another aromatic dicarboxylic acid, the polyamide-imide concentration therefore being from 4 to 35%, then by dilution in a polar solvent at a temperature of between 120 DEG  and 200 DEG  C. The solutions thus obtained are limpid at ambient temperature, capable of being stored and have an improved color.

Abstract: The invention relates to an apparatus for the treatment of liquids by permanent magnets, having a paramagnetic, tubular housing (1) through which the liquid to be treated can be caused to flow and in which ring magnets (3) and spacer rings (4) made of iron are arranged coaxially with the longitudinal axis of the housing, the housing (1) having connector pieces (7, 8) attached to both its ends and being provided in its interior with a helical conveying device (9) for the liquid to be treated. To improve the efficiency of the apparatus during water treatment, in respect of the precipitation of lime and the avoidance of lime deposits on the internal walls of water mains, and to improve the removal of old encrustations and to reduce corrosion of the pipe, it is proposed that the treatment apparatus be so designed that an interior plastic pipe which passes the liquid to be treated through the housing be arranged in the tubular housing (1), coaxially with its longitudinal axis (10) and at a distance from its internal wall, the opposite ends (17, 18) of this interior pipe being connected in a liquid-tight manner to the connector pieces (7, 8), whose flow cross-section widens towards the housing ends (5, 6), that the helical conveying device (9) be arranged in at least one of the two widenings (13, 14) of the connector pieces, and that the ring magnets (3) and spacer rings (4) be installed one behind the other, in the direction of the longitudinal axis (10) of the housing, in the liquid-free space between the interior pipe (2) and the tubular housing (1). <IMAGE>
