Patent number: 7971848Abstract: An In-Situ gel casting machine comprising a gel casting stand (1), a rubber cushion (2), and a locking base (3). Overlapping a notched glass (121) with a glass plate (122) tightly together will form a gel room (123), it is called as the slab gel casting mold (12). Put the same two slab gel casting molds (12) into each side of the portable casting stand (11) along its insides, and then insert the wedge frames (13) against each slab gel casting mold (12), which will form the gel-casting stand (1).

Patent number: 5228395Abstract: A method and apparatus for processing cheese comprises charging molten process cheese into a mold consisting of a plurality of cardboard lined, open-ended mold cavities oriented in spaced rows and circulating cooling air between and around each row to effect cooling of the cheese to the desired temperature. The rows of columns are defined by pairs of parallel side panels and crossed partitions formed of a rigid material and defining cavities which are elongate and rectangular in cross section. Support members hold the rows of columns in a parallel, spaced apart relation. After cooling, the mold is elevated, allowing the cheese columns covered by cardboard to be discharged from the lower ends of the mold cavities.Type: GrantFiled: July 3, 1991Date of Patent: July 20, 1993Assignee: Welcome Dairy, Inc.Inventor: Lea Eggebrecht

Patent number: 5167842Abstract: An installation for the fabrication of a series of cells constituting a single construction unit such as a dwelling house or a building story includes a fabrication bed which carries members for subdividing a single placement of concrete into serveral distinct slabs each forming part of one cell. These subdividing members are removably fixed on the fabrication bed in various positions according to the intended width of the cells. The subdividing members carry a device for temporarily immobilizing the two prefabricated panels placed on each side, each device being constituted by a post, the lower end of which can be fixed in an adjustable position on the corresponding subdividing member, and by an external shore of adjustable length.Type: GrantFiled: November 8, 1990Date of Patent: December 1, 1992Assignee: Entreprise VercellettoInventor: Michel Vercelletto

Patent number: 5046941Abstract: An apparatus (40) for molding a thin walled plastic shell includes a mold box (42) having an inner mold surface (48). A powder box (52) includes an internal chamber and first divider wall (54) for separating the internal chamber into at least two sections (56,58). A carrier framework (60) is removably mounted on the mold box (42) and includes a peripheral seal for perfecting a seal between the mold box (42) and the powder box (52) when the same are connected thereto. A second divider wall (64) is connectable to the first divider wall (54) separating the inner mold surface into two chambers continuous with the two sections of the powder box (52). The carrier framework (60) further includes a mold surface seal (66) for perfecting a seal between the second divider wall (64) and mold surface (48).Type: GrantFiled: October 13, 1989Date of Patent: September 10, 1991Assignee: Davidson Textron Inc.Inventors: Bruce A. Batchelder, John D. Gray

Patent number: 4950434Abstract: An arrangement for casting in a mould of so-called battery design longitudinal concrete bodies with a high degree of linearity. The moulds consist of pipes of substantially circular cross-section, these being placed on top of beams which, within a frame, extend parallel to the longitudinal sides of the frame. The beams constitute lower casting boundaries in the process of casting and each two adjacent pipes constitute two lateral boundary sides in the process of casting. The underside of each mould pipe is levelled and provided with a longitudinal rail of upside-down T-shape, which is cut out at several points and at mutually identical distances. A plurality of plates each with a Y-shaped recess are placed between the top edges of the beams and at the same distances as the cut out rails. The recess matches the leg of the T-rail, and pipes are rigidly secured atop the beams by joined T-rails and plates.Type: GrantFiled: February 5, 1987Date of Patent: August 21, 1990Assignee: Permaban Southeast, Inc.Inventors: Stig-.ANG.ke Ljungkvist, Lennart Johansson
