  • Patent number: 4629099
    Abstract: An escapement device to be disposed between a source of fluid and a receiver of fluid. The device allows fluid to escape from the source and then intermittently takes a fixed, measured quantity of such fluid and transfers that quantity to the receiver. The device is useful in intervenous infusion systems, automatic blood testing equipment, and like equipment where small but highly accurate measures of fluid are needed.

  • Patent number: 4618079
    Abstract: A refractory, heat-insulating slab for use in an inner, expendable lining of a tundish has a facing comprising magnesium oxide, inorganic binder but substantially no organic matter and a different backing. The facing has a combined water content not exceeding 2% by weight and the backing has a permeability of at least 10 AFS units. The facing and backing are joined together during formation of the facing or the backing. In the continuous casting of steel, the slabs have the advantage that there is little or no tendency for a significant amount of hydrogen to be picked up by the steel.

  • Patent number: 4618078
    Abstract: A vented, nestable-extendable pouring spout for use with a container having an opening therein includes an annular mounting portion adapted to be secured to an annular lip encompassing the opening of the container. A generally funnel shaped flexible body portion is secured at its larger circumferential edge to the mounting portion and at its smaller circumferential edge to a tubular neck portion located inwardly of the mounting portion. The body portion has an invertible fold portion adjacent the mounting portion to which is attached a plurality of circumferentially spaced ears, each ear having a pair of cylindrically shaped nibs extending therefrom. In the nested orientation of the spout, the ears extend downwardly out of the way of the nested neck and body portions. As the spout is extended, causing the invertible fold portion to invert, each ear rotates inwardly about its point of attachment until the ears extend inwardly perpendicular to the longitudinal axis of the spout.

  • Patent number: 4616768
    Abstract: The invention relates to a container for flowable or otherwise extrudable materials, the container having a discharge barrier which comprises a dividing wall dividing the container space into an outer chamber which is in communication with a dispensing opening of the container and into a storage chamber in which the contents can be subjected to pressure for dispensing from the opening and can thereafter again be relieved of pressure. The dividing wall is formed with a membrane section having at least one valve opening which upon pressure loading of the membrane section from the side of the storage chamber opens against a restoring force exerted by a membrane mounting and which upon relief from pressure automatically closes again under the restoring force. The dividing wall is also formed with a holding element which is connected to the container in a manner that takes up manufacturing tolerances.

  • Patent number: 4606479
    Abstract: A pump for dispensing liquid from a container is disclosed and comprised a cylinder, and a piston having an interior chamber with a valve member disposed therein, the valve member having a cylindrical surface at one end portion thereof. An inlet valve is provided and includes a sleeve having a cylindrical surface having a diameter sized to frictionally engage, provide a liquid seal and slide with respect to the cylindrical surface of the valve member. The inlet valve sleeve seats upon an annular ring extending around the inlet opening of the cylinder and seals the interior chamber of the pump with respect to the container. In accordance with an aspect of the invention, the pump may be non-venting such that a vacuum builds in the container as liquid is dispensed, and a sealing collar is provided to seal the pump with respect to the container.

  • Patent number: 4601415
    Abstract: A vortex inhibitor for use in tundishes, ladles, or metal making furnaces prevents the contamination of high quality molten steel by the slag layer which rides atop the surface of molten metal within such receptacles comprises a tapered polygonal body of castable refractory material whose specific gravity is less than the specific gravity of the molten metal but greater than the specific gravity of the slag. The refractory body is buoyantly supported at the interface of the layer of slag and the molten metal and includes a weighted apex so that the apex depends toward nozzle opening within receptacle. Thus, the body centers itself within the swirl of fluid generated during discharge of the fluid through the nozzle, and the inertia of the body substantially deenergizes the vortex so as to avoid formation of a suction funnel which typically draws the slag layer into and through the nozzle with the molten metal below the previously known critical level within the receptacle.

  • Patent number: 4588536
    Abstract: An apparatus for supplying gas to a liquid in a container (4) having a gas conduit (5) discharging thereinto, the apparatus being particularly intended for preparing aerated beverages on a small scale. In the upper part of the container there is provided a filling orifice (6). To simplify the use of the apparatus and to prevent mistakes, the orifice (6) is provided with a closure means (27) which is arranged to close the orifice automatically in conjunction with charging gas to the container (4). In this respect, the closing movement of the closing means is preferably arranged to be initiated by the stream of gas entering the container. To provide a safer and more positive apparatus, the apparatus is suitably designed so that the closing of the closure means (27) can only be initiated when the container (4) is filled with liquid to a given level.

  • Patent number: 4570832
    Abstract: A dispensing device in the form of a caulking gun is adapted to receive interchangeable cartridges. In addition, it comprises means introducing compressed air at activation into the cartridge from behind so as pneumatically to press a piston plate present therein and consequently the material present in the cartridge forward towards the discharge nozzle of the cartridge. In order to permit an easy interchanging of the cartridge as well as to obtain a very simple caulking gun, the dispensing device comprises an open supporting means and a sealing piston. The sealing piston is adapted to be sealingly pressed against the rim of the cartridge from behind so as to close said rim when the cartridge is pressed against the front end of the supporting means. At the same time the caulking gun comprises a passage extending through the sealing piston so as to permit compressed air to enter at the rear end of the cartridge at activation.
