Abstract: The present invention generally provides mold modules for constructing boat hulls, methods of constructing boat hulls using the mold modules, and hulls constructed using the mold modules. The modules may be adjustable, and may be included in a kit for building the hull of many boats of different dimensions but generally the same shape. Each mold module generally comprises a mold in a shape complementary to that of a portion of a boat hull, and an edge mold to form the edge of the hull part formed by that mold module. A mold module according to the present invention may also comprise one or more mold adjustment areas, and calibrators for selecting the boat hull dimensions. Methods for using the aforementioned mold modules generally comprise steps of molding hull parts, removing them from the mold modules, aligning them and finally attaching them together.

Abstract: The concepts disclosed herein provide for a concrete mold that improves upon existing concrete molds known in the art. The hinged side-panel members that are locked to a hold-down frame allow for the mold to cure a concrete member, and then allow the concrete member to be removed without the need to break-down the frame surrounding the concrete member. During the pouring and ensuing curing process of the concrete member, the hinged side-panel members are secured to the hold-down frame and to each other in order to hold the concrete in the mold. Once the concrete is cured, the hinged side-panel members may be unlocked and opened quickly, allowing for expedient removal of the concrete member. After closing and re-locking the hinged side-panel members, the mold may be reused to cure another concrete member without the need to rebuild the frame around the mold.

Abstract: A modular form has stackable upper and lower forms for casting concrete highway barriers. The lower form has opposing lower faces spaced apart to define a lower mold cavity, ties removably extending through the lower faces and lower mold cavity, and attachment angles extending along the top edges of the lower faces. The upper form has opposing upper faces spaced apart to define an upper mold cavity, ties removably extending through the upper faces and upper mold cavity, and attachment angles extending along the bottom edges of the upper faces. After the upper form has been stacked atop the lower form, fasteners are employed to removably secure the attachment angles of the lower form to those of the upper form. Thus, the upper and lower mold cavities are vertically aligned to create a combined cavity for forming a concrete highway barrier.

Abstract: The present invention generally relates to a foldable baking pan which is formed by locking four panels onto a bottom panel. Each of the panels have a grasping portion which mates with a corresponding portion on the underside of the bottom panel. To assemble the pan for use, the grasping portions of the panels and the bottom panel are first mated. The panels are next rotated to an upward position to form the pan. The panels are then locked into place. The assembled pan may then be used for baking or other suitable uses. The pan may be easily disassembled for cleaning and/or storage.

Abstract: A storage vault includes an inner tank entombed within a concrete outer tank by first erecting a pair of sidewall forms on a base plate to create an open-top enclosure. The wall forms are securely clamped together. A layer of concrete is then poured onto the base plate and the inner tank is restrained by lowered onto the layer of concrete.

The inner tank is a pair of reinforced hold-down bars extending over the top of the enclosure and having a pair of downwardly extending hold-down tubes which contact the top of the inner tank. Back hold-down bar is forced downwardly by a chain which passes over the hold-down bar and is fastened to the base plate. After the concrete has set sufficiently, the hold-down bars and tubes are removed and the holes created by the hold-down tubes are filled with concrete.

The openable side comprises a detachable side plate whose height is slightly above the level of soybean milk to be put in a coagulating box at a time and a reinforcing plate. The detachable side plate can be detached or fixed by unlatching or latching. After soybean milk coagulates and a block of coagulated bean curd is cut into pieces of bean curd, the detachable side plate is detached and the coagulating box is put in a water tank and is placed on a conveyor to transfer cut pieces of bean curd in the box onto a conveyor by pulling the box up diagonally.

Abstract: A mold comprising mold halves separable along a parting line has a rotating lifting handle carried by one of the mold halves, where the handle rotates between a first position in which it lies generally flat against the mold and a second position in which it extends outwardly from the mold to permit engagement by a lifting hook or the like. By this invention, rotation of the lifting handle from the first to the second position is prevented when the mold halves are separated along the parting line by more than a predetermined distance. Thus the mold cannot be lifted, since the handle cannot be rotated into outwardly extending position to receive the hook until the mold is closed. Additionally, this invention may be used to prevent opening of the parting line between the mold halves when in closed relation, while the handle is in the second position.
