Abstract: A steel-body vessel, suitable for storing ultra-high purity gases, has a relatively inert metal lining which covers the interior surface of the steel vessel body, preventing the stored gas from making any contact and reacting with the steel vessel body. The relatively inert metal lining extends into the vessel end pieces which are interiorly threaded, in the steel, proximate the relatively inert metal lining. The surface of the inert metal lining is conditioned to be smooth, preferably to 15 ?Ra or better. The vessel end pieces are sealed with end closure devices, which are secured by a securing portion carrying exterior threads to matingly engage the interior threads on the vessel end pieces. The end closure devices contain a sealing portion constructed of the relatively inert metal, which retains an annular sealing gland to seal the vessel in a removable, non-contaminating manner at service pressures when the end closure device is seated within the vessel end piece by means of the securing portion.

Abstract: A method of feeding work products such as can ends between different processes having different throughput requirements uses various feeding apparatus. In the first process, the work products are continuously mechanically treated at the same time by a group of first machines and then continuously discharged to a second process. This second process receives the work products fed from the plural discharging parts of the first machines. The apparatus in the second process has fewer receiving inlets than discharge parts of the first machines. In the second process, the work products are further mechanically treated. The method feeds the work products discharged from the plural discharging parts in the first process along respective feeding paths and then quickly feeds a predetermined number of work products to form a group of work products. This group is held in an arranged state in respective stay parts connected to the feeding paths.

Abstract: A machine and process for making container lid assemblies with a flexible membrane with a pull tab adhesively secured to a rigid ring so that when desired the membrane can be peeled off and removed from the ring to provide access to the container. Individual membranes are cut and separated from a web by rotating dies and individually transferred, accelerated and applied by a rotating anvil cylinder and transfer roller to individual rings which have been preheated sufficiently to activate an adhesive to adhere the membrane about its periphery to the ring. The rings are heated by an induction coil and a downstacker deposits heated rings on a moving conveyor belt which conveys them under the transfer roller where they are urged into firm engagement with a membrane by a resilient applicator pad on the transfer roller and an underlying support roller.

Abstract: A method of manufacturing a container cap with a concealed mark is disclosed. The mark is provided to the central portion of one of both the inside face of the top panel and one side of a seat member made of a thermoplastic material. The seat member is then placed on the inside face of the top panel so that the one side of the seat member faces the inside face of the top panel. The seat member is thereafter heated for softening. The other side of the seat member, heated and placed on the inside face of the top panel, is depressed to form a manually tearable line surrounding the mark in the other side of the seat member, thus defining a gasket portion in the seat member outside the tearable line and a manually removable portion, overlying the mark, inside the tearable line, and to attach a gasket portion to the top panel.

Abstract: In the formation of a valve mounting assembly for aerosol containers and the like, an aerosol valve mounting cup including a projecting central cylindrical body with an outwardly directed annular channel about the end thereof, an annular planar gasket deformably receivable within the channel, and apparatus for positioning the gasket in the channel. The inner periphery of the gasket defines a diameter substantially less than that of the cylindrical body whereby forceable engagement of the gasket about the body and into the channel outwardly deforms the inner peripheral portion of the gasket into a sleeve-like configuration intimately engaged with the cylindrical body thereabout, the remainder of the gasket seating within and conforming to the annular channel. Engagement of the gasket into the channel utilizes a gasket receiving bushing with a longitudinally moveable inserter therein which forces the gasket into the channel as the apparatus moves over a mounting clip.

Abstract: Method and apparatus for forming end closures for containers complete with a peripheral curl for attachment to the top of a container without press modification includes a unique split die core ring. The method includes performing the operations of blanking the end panel against the cut edge, forming the chuckwall against the die core ring with a punch and punch shell and finally setting the chuckwall by wiping over the radius of the die core ring against a fluidly supported piston and simultaneously applying a curl to the peripheral edge of the panel prior to completion and removal from the press station. The method is performed by utilization of a split die core ring having inner and outer concentric segments, the outer segment of which is withdrawn as the punch shell advances to initiate a curl between the inner face of the punch shell and the outer face of the fixed inner segment of the die core ring.

Abstract: Apparatus is provided for handling gasket-forming material. This material is usually supplied in tubular cartridge form and is dispensed to a screen with a porous pattern which shapes the material to the desired gasket-configuration. The material is spread on the screen and forced through to the other side where the gasket pattern is applied to an adjacent transfer surface of a transfer pad. This pad with the pattern on the transfer surface is moved to a mateable surface of a workpiece located on a support spaced from the screen. The gasket-forming material is then transferred to the mateable surface. The gasket-forming material is dispensed from the cartridge with the aid of a cartridge holder having an opening at one end to receive a spout of the cartridge and having a plunger at the other end with a plunger rod extending outwardly therefrom. A fluid-operated cylinder is aligned with the plunger rod and has a piston connected with the rod.
