Abstract: A heater device for tightening a coil on a cylindrical body which forms a passageway between an injector and a mold in an injection molding apparatus. The device has a first anchor for connecting one end of the coil to the cylindrical body, and a second anchor for connecting the second end of the coil to a rotatable ring on the cylindrical body. A threaded portion is arranged on the rotatable ring so that it engages directly with the cylindrical body or with a stationary ring member on the cylindrical body in a manner similar to a worm gear mechanism. Due to the rotation of the threaded member, a force is generated to stretch the coil, thus bringing the coil into positive contact with the surface of the cylindrical body along the entire length of the coil.

Abstract: A fluid operated press having opposed first and second fluid chambers is employed for compressing a mixture of desired brick ingredients in a mold. Pressurized fluid, preferably hydraulic oil, is first delivered to the first fluid chamber of the press to cause the same to exert a prescribed pressure on the mixture. Then, with this prescribed pressure maintained, the pressurized fluid is directed alternately into the first and second fluid chambers at rapid intervals, with the result that the press imparts vibratory motion to the mixture being held under pressure. In a preferred embodiment, the selective delivery of the pressurized fluid to the fluid chambers of the press is controlled by a servomechanism, constantly comparing a reference pressure signal with an actual pressure signal representative of the actual pressure being exerted by the press and actuating a servovalve so as to make the difference between the reference and actual pressure signals zero.

Abstract: A tire press, loader and method employs a stationary bottom mold section and a vertically movable top mold section which moves upwardly to open the press clearing the area therebetween for discharge of the cured tire and loading of the green or uncured tire. The press loads the green tire initially into the top mold section centering and holding the top bead of the green tire on the bead ring of the top mold section. To position the uncured tire for such top loading there is provided a loader which engages the uncured tire at the lower shoulder of the tread area. The loader includes pivotally movable chuck sector assemblies, each mounted on a ring. The ring can readily be centered with respect to the axis of the mold sections and each assembly can be moved concurrently uniformly radially of the ring to accommodate tires of different sizes.
