  • Patent number: 7937956
    Abstract: A method and apparatus for the manipulation and management process of cryogen such that it controls both the fluid body movement as well as internal currents within the cryogen. Small volumes of a desired substance introduced into this managed cryogen for the production of frozen or solidified pellets or granules are better managed as to shape, size, deformation, frozen satellites, fines and agglomeration and overall desired quality. These benefits result from the dispersion of the gas produced, as well as the heat transferred, resulting from the introduction of the relatively hot substance to the cryogen. The fluid body movement assists in maintaining a distance between the individual solidifying pellets or granules thereby minimizing deformation as a result of physical contact. The output characteristics and desired quality of the pellets can be more effectively controlled and managed, as desired.

  • Publication number: 20100203214
    Abstract: The present invention is directed to formulations of the premix utilized in the production of a pellet structured frozen dessert type product. The pelletized frozen dessert product is manufactured by introducing the liquid premix into a body of a cryogen such as liquid nitrogen such that the small volume of liquid premix is frozen rapidly. The invention elevates the melting temperature as well as the fusing temperature of the finished pellets such that the storage and serving temperatures of the pellets are similar to the bulk products. The invention utilizes the basic formulas and names and flavors associated with bulk type frozen desserts such as Ice Cream, Sorbet, Water ice, Ice Milk, Frozen Yogurt and similar type products. The pellet produced utilizing the pre-mix is structurally stable at normal retail and home freezer situations. The formulation and manufacture of the pelletized dessert product is substantially different from bulk frozen desserts: it is in itself a unique type product.

The invention elevates the melting temperature as well as the fusing temperature of the pellets such that the storage and serving temperatures of the pellets are similar to the bulk products. The invention utilizes the basic ingredients and names and flavors of bulk type frozen desserts. The pellet produced utilizing the pre-mix is stable at normal retail and home freezer situations. The formulation and manufacture of the pelletized dessert product is substantially different from bulk frozen desserts. The result is a product that maintains the desired individuality of the pellets while maintaining structure, such that fusing is inhibited at the storage and serving temperature.

  • Patent number: 4741433
    Abstract: The invention relates to child resistant boxes of the type where a storage container slides in a closure sleeve. Such a box, according to the invention, may have sliding movement in two different dimensions to open or close the box. Opening movement in one of the dimensions may partially open the box and opening movement in the second dimension may fully open it. Closing is by reversing the movements. A latch is provided to keep the box closed. It is movable into a release position in which it does releases the container so that the box may be opened. The initial opening movement may suitably be rectilinear movement and the second movement may be rotary. The movement may be controlled by means of a cam slot on one of the housing or container engaging a lug on the other.
