Abstract: A parison tube former utilizes a radial compression heater to heat a very specific portion of a preform tube for stretching. The heater has a plurality of compression dies that form a central cavity for receiving the preform tube. The working surfaces of the compression dies close down onto the outer surface of the preform tube to heat the tube via conduction, which more accurately and precisely heats the preform tube. A first stretched portion of the preform tube is produced by stretching the preform tube after heating. A second portion of the preform tube is then located within the central cavity and is also heated by the radial compression heater and stretched to produce a second stretched portion of the preform tube and an unexpanded portion of the preform tube, or balloon portion of the parison tube.

Abstract: An artificial flower, plant, or other botanical is produced from an aqueous agar-based solidifying mixture. The artificial botanical may be colored as desired by adding one or more colorants. The artificial botanical may also be scented by adding a perfume, odorant, or other scent. Because the artificial botanical is produced using the aqueous agar-based solidifying mixture, no animal-based gelatin products are used. The artificial botanical may thus also be edible and satisfies vegan diets. The artificial botanical may thus also be flavored by adding a flavoring, such as fruit, concentrate, or sweetener. The artificial botanical may be all-natural and edible by adding mica powder as the colorant and by adding glycerin as the flavoring.

Abstract: A device for annealing glass panes includes rollers for transporting the glass panes and two sets of slit-shaped nozzles, which run parallel to the axes of the rollers and from which cooling air can be directed onto both sides of the glass panes. In the device, cooling air acts as effectively as possible on the two surfaces of the glass pane, and anisotropies and stresses within the glass are reduced. This can be achieved by each nozzle being formed as a continuous flow channel, which extends over the width of the glass panes and on both parallel running sides of which partitions are arranged, for the forming of a flow pocket assigned to this flow channel. The cooling air that comes back from the glass panes is returned between this flow channel and the associated partitions.
