Abstract: An adhesive composition for bonding polished metal surfaces to vinyl chloride polymer coated metal substrates is disclosed which is comprised of a thermoplastic vinyl chloride polymer resin, a thermosetting epoxy resin normally incompatible with the vinyl chloride polymer resin and an amount of an acrylonitrile/butadiene/styrene copolymer which imparts compatibility between the epoxy resin and the vinyl chloride polymer.
Abstract: A remote recording and playback system comprises a recording unit for recording analog data received virtually simultaneously over a plurality of analog input channels, and a playback unit for playing back said recorded analog data for a given one of the plurality of analog input channels. The recording unit sequentially scans the plurality of analog input channels in succession to derive respective analog data samples, converts the respective analog data samples to digital form, and stores the digital representations of the analog data samples in a random access memory. The playback unit accesses the random access memory in the recording unit, converts the digital representations derived therefrom to analog signals, and displays the previously recorded analog data, one channel at a time. The system is further characterized by the storage and retrieval of "drift" and D.C.
Abstract: A container is provided for liquid carbonated beverages having applied to the internal wall surfaces a layer of an inert, water insoluble polymeric material comprised of a predominant amount of hydrophilic groups, the presence of such hydrophilic groups in the polymer being effective to reduce carbon dioxide bubble nucleation and accompanying carbonation loss from carbonated beverages packaged therein.
Abstract: A removable closure for a pressure container having an opening with a peripheral bead into which there is inserted a threaded neck member, the neck member being formed of a resilient plastic material adapted to expand and contract and having an interlocking engagement with the bead. The neck is provided with a radially extending handle portion by means of which the container is adapted to be carried and which also serves to prevent rotation of the neck member upon the application and threading of a cap to the neck member, the cap having a plug portion which enters into the opening in the neck member and being tapered wedges into the neck member and spreads the portion of the neck member which is in radial alignment with the bead portion, thus tightly forcing such portion against the bead to provide a high pressure seal.
Abstract: A container and method of adhesive bonding of two telescopic container halves wherein each container half has a cylindrical body, the inner container portion being circumferentially loaded to temporarily reduce its diameter and being forced in centered relation to the outer portion into a bead of adhesive laid in the interior of the outer portion to coat the raw edge on the inner portion, the inner portion shearing through the adhesive without wiping it off from the interior of the inner portion and thereafter the hoop stress on the inner portion being relieved so it springs out and squeezes excess bonding material from between the inner and outer portion and thus obtains a thin film adhesive bond with good stress shear characteristics while holding the film in compression therebetween during curing or setting of the adhesive.
Abstract: A closure for a container wherein a tape having a metal part and thermoplastic material which is applied to the container wall and heated. Most of the material is squeezed out from between the metal part and the wall into a rib which is formed during application. The material in the rib has an isotropic structural characteristic since the rib formation provides a region into which the excess material is directed minimizing the shearing effect of the flow of material along the interface with the container wall. Also the rib reinforces the tape in the critical region to resist pressure of gasses in the container when used to contain carbonated beverages. This patent covers a method of making the above described closure.

Abstract: In a process for producing a tubular collagen casing from a hide collagen source which comprises the steps of comminuting said collagen and forming a slurry, swelling said collagen with acid, then extruding, coagulating, tanning, and drying, the improvement which comprises the steps of substantially completely swelling collagen, in which the epidermal layer and hair has been removed, with a relatively concentrated weak non-toxic acid having a dissociation constant in water of from about 1.times.10.sup.-6 to about 1.times.10.sup.-3, e.g., lactic acid, citric acid, etc., for a time sufficient to effect substantial swelling of the collagen and then comminuting the collagen for forming a slurry. An advantageous feature of this improvement is that it permits forming desirable collagen casing from a collagen source obtained from a hide which has been subjected to substantial liming.
Abstract: A multipackage assembly for two large containers each of which has a handle with means for releasably interlocking with each other for holding the upper ends of the containers together, the lower ends of the containers being held together by a releasable band.
Abstract: A dual cable conveyor and a turn comprising two parallel horiztonally running container-conveying and supporting cables. The cables run in parallel tracks and both simultaneously support the can which straddles the cables. At the turn, an upper and a lower sheave are provided independently rotatable about a common vertical axis. Each sheave has a peripheral groove defined by a narrow upper flange and a wide cable-supporting lower flange. The upper flange is less than the radius of the cable and the lower flange is greater than the radius but smaller than the diameter. The inner cable rides about the upper sheave which is smaller and runs faster than the lower sheave. The inner cable has lengthwise thereof its upper sector tangential to the outer periphery of the upper sheave and therewith supports and advances the cans between appropriately curved inner and outer guide rails.
Abstract: A tape made of a laminate of thermoplastic plastic material and metal having a finger ring portion in which the edge of the hole is hemmed by folding the plastic portion upon itself and heat sealed to each other.
Abstract: Highly elastic films, filaments, and shaped articles can be prepared from amylose by forming a dispersion or solution of amylose in an appropriate liquid vehicle under conditions in which the molecular conformation of amylose is substantially helical, then forming a shaped article, film, or filament from the dispersion or solution and finally crosslinking the amylose with a crosslinking agent, the crosslinking agent being present in a proportion for providing an average of about 1 crosslink per 500 amylose monomer units to about 1 crosslink per 10 amylose monomer units.
Abstract: Polyolefin containers having improved gas barrier properties are compression molded from billets formed from polyolefin resins filled with inorganic fillers. The gas barrier properties of the containers are stabilized against loss under conditions of sterilization by treating the fillers with a polar silane compound.
Abstract: A container having a rigid wall with a sacrificial anode non-removably attached to the inner surface thereof. Both the container wall and the anode are formed with nested integral rivets, whereby the anode is held in close contact with the container wall. Formation of the rivet on the container wall causes fracture of the protective enamel or lacquer coating thereon, and exposure of the underlying metal, whereby electrical contact between the anode and the container wall is established.There is also disclosed a method or methods of achieving the attachment of the anode to the container wall in accordance with the present invention.
Abstract: A portion of the oil-in-water emulsion used as a lubricant/coolant in the shaping of metal articles such as containers is subjected to a reverse osmosis or ultrafiltration process to concentrate the oil portion and separate a water permeate. The oil concentrate is reincorporated in the remaining portion of the coolant and the permeate is used as rinse water to remove oil residues retained on the article from the metal shaping operation. The coolant is then reconstituted with the oil residue rinsed from the article.
