  • Patent number: 3960296
    Abstract: An adhesive dispensing gun for translating solid slugs of thermoplastic feedstock from the solid state to a molten state. The gun is pneumatically cooled to control solid/melt feedstock interface within the gun's barrel and is pneumatically powered to discharge the molten feedstock in response to operation of a trigger. The gun barrel includes a forming die adapter or sleeve located partially upstream of the solid/melt feedstock interface. The upstream end of the adapter or sleeve is flared inwardly so as to form a section internally of the barrel for reforming or reshaping varying sized slugs as they enter the forming die adapter and while the entering section of the slug is still in a solid state. The forming die adapter thus enables the adhesive gun to accept varying sizes of slugs while preventing meltback along the exterior of slugs which are nominally substantially smaller in diameter than the inside diameter of the barrel.

  • Patent number: 3955665
    Abstract: A continuously driven endless belt type conveyor is disclosed as being employed to transfer packages successively through a weighing station having a weighing platform on which packages rest during weighing thereof and a package labeling station. A flight of the conveyor passing through the weighing station is adapted to be lowered and raised for the purpose of removably placing a package in resting engagement with the weighing platform, while concurrently having its speed of travel relative to the platform varied to effect deceleration of the package prior to weighing and acceleration of the weighed package prior to discharge.

  • Patent number: 3949912
    Abstract: A glass container is molded with a recessed outlet end having a sharp outer edge and an enlarged lip. The outside surfaces of the lip of the container from a point adjacent the recessed opening are straight in part and convexly shaped in another part and terminate in a portion of reduced diameter at the neck of the container. A closure assembly centrally housing an aerosol "or pump-type" valve is formed with a depending flange, an annular stepped portion adjoining the central housing, and a concave surface portion connecting the stepped portion and the depending flange. A liquid elastomeric resin lining is flowed onto the concave surface and depending flange portions and cured to form a resilient liner. The closure assembly is then mounted upon the recessed open end of the glass container forming an inwardly diverging channel between the recessed outlet and enlarged lip of the container on the one hand and the stepped and concave portions of the closure assembly on the other hand.

  • Patent number: 3946900
    Abstract: A system for dispensing a selected amount of liquid from apparatus such as a service station gasoline pump. Low pressure air is directed through air passages in response to valve means carried by the pump indicator dials. The amount desired to be dispensed is entered into the system through a selector valve means, which allows air to actuate the hose nozzle automatic cut-off device when the desired amount, or an amount slightly less than the desired amount, has been dispensed.

  • Patent number: 3942916
    Abstract: A dosing device for dispensing very small quantities of liquid includes a variable displacement piston for varying the pressure within a chamber and valves located in inlet and outlet ducts communicating with the chamber. The valves preferably comprise a disc having a circular periphery and including passages therein which are radially spaced from the central portion of the disc. This central portion engages a valve seat to close off the corresponding duct and is preferably rigid to prevent permanent deformation of the disc. The peripheral edges of the disc are received in an annular groove and are free to move radially therein.

  • Patent number: 3935969
    Abstract: A bung screw-threadedly received in a receptacle has a plurality of flow openings therethrough disposed in a series about the axis of the bung, and an axially movable valve disc for simultaneously opening or closing all of the openings. Each opening has a thin penetrable closure which can be penetrated without disturbing any of the other closures. In this way, when the container is tilted to discharge the contents, only the closure of the flow opening which is lowermost need be broken. The disc can then be manipulated to open and close the bung, without the contents of the container flowing over the tools and the hands of the operator who opens and closes the disc.
