摘要:
A device for heating an article, especially a heat recoverable article, by means of a gas heating tool comprises an element which is preferably hollow and is heated by a flame from the tool, means for positioning the article within the element and a support for retaining the element on the heating tool. In use, a flame from the tool is directed on to the element and the article is heated over a major part of its surface by radiant heat emitted by the element.
摘要:
A heat-recoverable closure device including a tubular member having an opening defining a means for readily communicating with articles disposed within the tubular member after heat-recovery. The closure device includes compression means attached adjacent and generally normal to each portion of the tubular member having an opening. The compression means further includes structure for maintaining it in constant compression during heat-recovery for preventing crack propagation.

The present invention relates to a method for fabricating ultra-thin films of pyrolytic carbon. Pyrolytic carbon is vapor deposited onto a concave surface of a heated substrate to a total uniform thickness in the range of about 0.1 to 1.0 micrometer. The carbon film on the substrate is provided with a layer of adherent polymeric resin. The resulting composite film of pyrolytic carbon and polymeric resin is then easily separated from the substrate by shrinking the polymeric resin coating with thermally induced forces.

A system for forming twisted pultruded fiber reinforced rods is disclosed. In the system of the invention fibers are coated with a resin, drawn through a shaping die and then after at least partially curing, the rod is simultaneously twisted and pulled through the coater by opposed pulling surfaces that rotate as they pull to twist said rod.

The spigot end of a tube made of hard polyvinyl-chloride (PVC) is fit into the heat-shrinkable bell end of a similar tube. A hot thermally-activatable adhesive is injected into the space between the bell and spigot so that it heats and shrinks the bell, causing it to compress and distribute the adhesive mass throughout the joint. The bell is formed with a circumferential bulge forming an inwardly opening circumferential recess into which the adhesive mass is injected through at least one radially opening hole. The mass of adhesive in this groove serves as a hot reservoir of glue during shrinking and distribution.

One embodiment is a shrink labeler for use to shrink a shrink label onto a bottle including: a containment wall having a gas/steam inlet; and a showerhead container capable of holding the bottle in close proximity to orifices disposed therein and having an aperture through which the bottle may be introduced thereinto; wherein the gas/steam inlet is coupled to a plenum disposed between the containment wall and the showerhead container.
