Abstract: A container having a container body, a thermic module at one end of the body, and a closure at the other end of the body initiates an internal exothermic (or, alternatively, endothermic) chemical reaction to heat its contents when a user actuates the thermic module. A plastic thermic module body is spin-welded to a plastic container body by rotating one relative to and in contact with the other. The container body has multiple layers, including an inner layer such as a so-called oxygen barrier layer that inhibits oxidation and spoilage of the contents, and spin-welding the container body to the module body seals the otherwise-exposed oxygen barrier layer against air or moisture intrusion. The container includes a rotatable cover adhered to the container end over the closure with heat-sensitive adhesive that prevents a user from accessing the contents until a certain temperature is reached.

Abstract: A self cooling can has water on a pre-wetted wick (478), in a chamber and an adsorbent in another chamber communicable upon actuation of the can with the chamber. One or both of the chambers is at low pressure. Upon actuation the pressure of the wick drops, water vapour is absorbed by the adsorbent from the internal atmosphere and more water evaporates from the wick to replace it, thereby causing a cooling effect in heat generated in the adsorbent may be contained by but a take-up system, such as phase change material or microcapsules of high heat capacity material such as water.

Abstract: An improved blast cleaning system and an improved method of blast cleaning using solid carbon dioxide pellets is provided. A compressed air source--preferably an air compressor--is used to produce a compressed air or carrier gas stream which is cooled to the desired temperature by injection of a cryogen--preferably liquid nitrogen--before the solid carbon dioxide pellets are introduced into the carrier gas stream.

Using a compressed air stream which is precooled to the desired operating temperature helps to minimize the sublimation of the carbon dioxide pellets. The use of the precooled compressed air stream also allows greater control of the hardness, size, density, impact forces, stripping rates, and stripping efficiencies of the carbon dioxide pellets. An improved method of transporting solid carbon dioxide pellets which can be used for nonblasting applications (e.g.

Abstract: The tube, known as a straw, according to the invention, is conventional in its form, and is constituted by a rectilinear length of transparent tubular envelope. In the vicinity of a first end, the straw contains a sliding stopper with a quantity of powder gellable by hydration between two porous pads. The tubular envelope is extruded from an ionomer resin marketed under the brand name of Surlyn 8921. Ionomer resins have, above and below a transition zone extending from 45.degree. C. to 60.degree. C. approximately, states that are respectively thermofusible and crosslinked. Thus, the straw can be closed by fusion of the ends clamped by heated jaws, while presenting suitable properties of rigidity at ambient temperature. Furthermore, the ionomer resin used does not have an embrittlement temperature, so that it can be manipulated at cryogenic temperatures (77 K.) without the need for taking any particular precautions. The filling and sealing of the straws can be automated, to ensure the safety of the operators.

Abstract: A method of and apparatus for bagging ice cubes produced by a plurality of cubers with only one bagger when the cubers are stacked side-by-side with the ice produced by each cuber falling into one of two hoppers. The ice is moved from each hopper alternately to the bagger. There each batch of ice cubes is dropped into a bag, the bag sealed, and moved to a storage bin positioned below the bagger.

The preferred embodiment of the present invention teaches an ice box rack sized and configured to fit the container of a variety of currently sold ice chests, the rack including as a novel and unique feature a planar lower surface to facilitate the uniform application of compressive pressure on the ice. It has been found that this uniform pressure acts to pack the ice, particularly crushed or chipped ice, causing it to melt less quickly, thereby prolonging the cooling process. The present invention may be configured in a variety of different ways, and may be constructed of a number of different materials, including extruded or molded plastics, wood, aluminum, or the like, all with satisfactory results. Further, the rack design of the present invention may be configured to support a variety of differently configured items, such as unpackaged or packaged foods, can beverages, bulk items, etc.

Abstract: A screened grid (1) is sized and shaped to fit inside of a cooler chest (4). Doors (9) in the screened grid (1) are provided for accessing sealed beverage containers (2) storable under the screen grid (1) in ice water, which cool the sealed containers (2) under the grid (1) and also cool and keep dry or unsealed food items positionable above the screen grid (1).

This allows everything to stay cool but not wet because the ice water drops below the grid and cools the sealed beverages and/or sealed food containers stored below the grid. The grid (1) can be constructed of materials which can be pre-cooled to aid cooling effect with a cooler chest (4).
