  • Patent number: 4538652
    Abstract: The present invention relates to a process and device for incorporating a dose of liqueur in a bottle of champagnized wine, wherein the device comprises a receptacle containing the liqueur which receptacle is connected to a pump from which the delivery is introduced near the bottom of the bottle. A tank under pressure containing champagne is connected to the interior of the bottle by a pipe provided with a valve. Another pipe with radial hole at the chosen fill level for the bottle emerges from the bottle and terminates in the tank. A conduit enables the bottle to be maintained at the same pressure as that prevailing in the tank. Via a channel in the head, the bottle may be placed under excess pressure to evacuate the surplus of wine via the pipe. The invention is particularly applicable to oenology.

  • Patent number: 4537232
    Abstract: Apparatus is disclosed for discriminating between desired and undesired fluids such as kerosene. The apparatus is especially adapted for improving the safety of kerosene heaters by discriminating between kerosene suitable for heater use and more volatile materials such as gasoline. Structure is disclosed to terminate flow of fluid to a kerosene heater in response to the sensed presence of a fluid other than kerosene. According to a preferred form of the apparatus, additional structure is provided to prevent fueling a kerosene heater by structure other than that operatively associated with fluid discriminating structure. According to the more specific aspects of the fluid discriminator, a float including magnetic or light-responsive actuators is calibrated to permit or cease the supply responsive to the position of the float in the fluid. A fluid less dense than kerosene, such as gasoline, will cause the float to sink within the fluid and thereby terminate the flow of fluid to the kerosene heater.

  • Patent number: 4531550
    Abstract: A plug assembly for use in a thermal-medium passage in a unit curtain wall, for example, comprises a circular gasket seat having a central cylinder with an annular elastomeric gasket placed on the gasket seat around the central cylinder, and a sleeve fitted over the central cylinder and fastened thereto by a fastener such as a hexagonal socket head cap screw threaded through a bottom of the sleeve axially into the central cylinder. When the plug assembly is to be put in the thermal-medium passage, the plug assembly is inserted into the passage with the fastener slightly loosened. After the plug assembly has been pushed to a desired position in the passage, the fastener is tightened by a tightening tool until the annular elastomeric gasket is resiliently squeezed between the sleeve and the gasket seat radially outwardly against an inner circumferential wall of the passage. A heat-transporting medium such as hot water can be prevented by the annular elastomeric gasket from flowing through the passage.

  • Patent number: 4522533
    Abstract: The present invention relates to a flow restrictor for insertion into the inlet of a pipe to restrict fluid flow within said pipe to a predetermined maximum. The flow restrictor is comprised of a tapered tubular hollow body portion having a smaller diameter and a larger diameter end. A cover plate is attached to the larger diameter end. An aperture having a predetermined cross-sectional area is located in the cover plate. The smaller diameter end is open to fluid flow. The predetermined cross-sectional area of the aperture determines the predetermined maximum fluid flow.

  • Patent number: 4518021
    Abstract: A machine for filling containers with a viscous product to a preselected fill level below the top of the container. The filling machine has a downwardly opening nozzle and a valve for controlling the flow of product through the nozzle. An elevator mechanism is arranged to elevate an empty container into telescoping relation with the nozzle and then allow the container to move downwardly as it is filled. A mechanism senses when the container support platform moves downwardly to a position in which the discharge end of the nozzle is adjacent the desired fill level on the container, and an elevator drive mechanism is operated to positively move the container downwardly off the nozzle to a position substantially below the lower end of the nozzle to draw product in the container from the product in the nozzle.

  • Patent number: 4518015
    Abstract: A novel inflatable plug for interrupting fluid flow in a pipe is provided which effects a stable, rigid seal while at the same time has a minimal axial length so as to be easily maneuverable. The plug is made from flexible, impermeable fabric and is provided with finely distributed, flexible inelastic connector elements or threads running in the axial direction and secured to opposed walls. When the plug is inflated, the threads prevent the opposed walls from separating a greater distance than the length of the threads. A complete plug assembly is also disclosed, comprising three such plugs in series, mounted on a bracing support frame and provided with a fail-safe inflation system.

  • Patent number: 4513893
    Abstract: A method and apparatus for spreading a foamable composition for forming a polyurethane foam. The foamable composition is uniformly spread on all of a surface which is moved by scattering the foamable composition uniformily in its transversal direction. The foamable composition is fed to spread on a first surface and then, the foamable composition is scattered from the first surface as fine particles to the second surface. For example, the foamable composition (10) is fed to spread on a pair of rotated spreading rolls and then, the foamable composition is scattered as fine particles by a pair of rotated scattering rolls (3), (4) which are respectively contacted with the spreading rolls. This can be used for preparing a polyurethane foam sheet or a laminated product having a polyurethane foam layer.
