A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage.
The concept of the Thingmaker was introduced in 1963, as part of Mattel's Vac-U-Maker set. This omnibus toy combined the new moulds and Plasti-Goop technology with the existing Vac-U-Form machine, a vacuum forming toy, which molded simple sculptures by heating thin sheets of plastic, then using a vacuum pump to form the softened plastic over hard plastic forms.
The Easy-Bake Oven is a working toy oven introduced in 1963 and manufactured by Kenner and later by Hasbro. [1] [2] The original toy used a pair of ordinary incandescent light bulbs as a heat source; current versions use a true heating element. Kenner sold 500,000 Easy-Bake Ovens in the first year of production. [3]
The sublimation that occurs at the solid-gas boundary (critical sublimation point) (corresponding to boiling in vaporization) may be called rapid sublimation, and the substance sublimes rapidly. The words "gradual" and "rapid" have acquired special meanings in this context and no longer describe the rate of sublimation. [citation needed]
The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...
In psychology, sublimation is a mature type of defense mechanism, in which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse.
PYD has even been used to help develop and strengthen the cultural identities of American Indian and Alaskan Native youth. PYD methods have been used to provide a supportive setting in which to engage youth in traditional activities. Various programs have been implemented related to sports, language, and arts and crafts.
