摘要:
An assembly for cutting and trimming a web of plastic film secured about the top of successive containers moving on an endless conveyor. Opposing clamps engage the top outer periphery of the container and provide support for a rotating cutter device. The cutter device includes a lower pressure ring connected by compression springs to a top support plate. The top support plate is secured to a rocker arm system which moves the device up and down over the container top. The spring mounted lower pressure ring operates to pin the film against the clamps while a concentrically mounted rotating bar having a downwardly extending knife blade at one end cuts the film radially outside the top edge of the container. The top support plate also includes a knife blade secured to one side thereof which severs the film web transversely of its length to separate the trimmed container from subsequent containers.

摘要:
An improved rupture disc pressure relief arrangement for use with a high pressure vessel is described comprising a rupture disc having one surface thereof exposed to the internal high pressure of the vessel and means for establishing a variable pressure at a second surface of the disc. A disc which ruptures at a predetermined differential pressure can be employed over a relatively large range of operating pressures by varying the pressure at the second surface when changes in the operating pressure are made. The need for replacement of the rupture disc with changes in the operating pressure of the vessel is thereby avoided.
摘要:
A plastic foam cup and method of producing it, said cup having thin walls and of a dimension which does not exceed twice the average diameter of foamed beads of plastic material in said wall, and wherein the structural density of the material of said cup ranges between 55 to 65 grams per liter, and the dimensional wall thickness of said cup ranges between 0.065 inches and 0.075 inches.
摘要:
A lid adapted to fit over the opening of containers and having a raised portion serving as an open spout for the container. The lid construction includes a central ring portion having a plurality of rib sections extending radially therefrom and terminating at a vented inverted U-shaped rim structure. The rib sections have raised points and the pour spout is recessed to provide for placement of containers in a stacked relationship.
摘要:
A system for improving the adhesion of labels to plastic coated bottles including a series of nozzles discretely aligned to disperse a flame over the outer surfaces of a bottle moving on a conveyor. An inline bottle cooling station is also provided comprising an endless porous belt operating in conjunction with a water spray. The bottles are initially spaced apart a predetermined distance on the conveyor, passed by the flame nozzles, and subsequently cooled with a porous belt and water spray assembly.

A panel construction toy including hollow body building elements capable of interengagement to form various constructional configurations; for example, house-like or other modular arrangements. The panel toy comprises wall, door, window and roof panels as well as coupling members adapted to interengage portions thereof, thereby securely fastening the panels together. The panel construction is further of such a character that the transitional point between panels is made in a smooth continuous fashion.
