A mold set for manufacturing interlocking construction blocks comprising a modular family molds and connecting side walls. The molds may be configured to create assembled female molds that may be filled with fluid cement, which can be removed from the female molds with corresponding male molds. Each assembled female mold may comprise one or more interlocking sections that allow the resulting blocks to interlock in three directions along three axes, including a left/right axis, a front/back axis, and an up/down axis. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights. The disclosed modular mold sets allow blocks to be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement.

An interlocking construction block system comprising a family of blocks that interlock along three axes, including a left/right axis, a front/back axis, and an up/down axis. The family of blocks are self-aligning and do not require skilled labor or mortar to create a structure of any length, width, height, or shape. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights and stresses. The disclosed blocks can be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement. The blocks may comprise channel openings to allow for plumbing, electrical, and structural reinforcements in the structure and may each be reinforced with an internal mesh cage.

A mould for the production of articles comprising a cavity for the retention of a fibrous material impregnated with a curable resin defined by a top, a base (1) and side walls (4, 5, 6, 7) and an internal insert (2) having sectional walls that can move independently of each other in order to exert pressure on the fibrous material.

A molded a product includes a body including a hollow interior region and a plurality of openings in communication between an interior region and an exterior of the body. The body is formed from a resilient material that enables the product to stretch and retract to an original shape without tearing or breaking when removing a first part of a core of a mold from a first portion of the interior region through a first opening of the plurality of openings and a second part of the core of the mold from a second portion of the interior region through at least one of the first opening and a second opening of the plurality of openings, the first and second parts of the core of the mold being larger than each of the plurality of openings.

The invention provides a culture plate made from a polymer incorporating a culture component releasable into culture media in the well, methods of culturing a microorganisms in the culture plate, and a methods of making the culture plate.

Tooling for manufacture of an apertured element made of a composite material includes first and second sole plates and tooling elements. Each sole plate is configured to be placed on either side of the apertured element to be manufactured. The tooling elements are placed between the first and second sole plates. The tooling elements include at least one core and peripheral bars. The core is configured to delimit a cell of the apertured element to be manufactured. The core is movable in translation along the first and second sole plates. The peripheral bars are placed on a periphery of the core and configured to delimit the apertured element to be manufactured. At least one peripheral bar is movable in translation along the first and second sole plates.

A segmented core (1) for molding of an impeller (12), especially a pump impeller, includes at least three segments (2). All of the segments (2) have the same form and each segment (2) has connecting devices (3, 3) for connecting the segment (2) with the adjacent segments (2). A method for molding an impeller (12) includes the steps of: providing a molding tool (14), providing a core (1) including at least three identical segments (2), which include the connection portions (3, 3) for connecting the segment (2) with the adjacent segments (2); assembling of the core (1); placing the core (1) in the molding tool (14); molding the impeller (12), ejecting the core (1) and the impeller (12) out of the molding tool (14); and removing the core (1) from the impeller (12).

A mold and a method of manufacturing GOS ceramic scintillator by using the mold are provided. The mold comprises: a female outer sleeve having a cavity disposed inside; a plurality of female blocks disposed inside the cavity, the plurality of female blocks being put together to form a composite structure having a vertical through hole; and a male upper pressing head and a male lower pressing head, wherein each of the male upper pressing head and the male lower pressing head has a shape consistent with that of the vertical through hole. The disclosure may reduce defects of the related art in hot-pressing-sintering such as a mold has a short retirement period and a high material waste, significantly reduce the cost for production of the GOS ceramic scintillator, and significantly improve a process economy.

A method of fabricating an airfoil element out of composite material, comprises: making a fiber preform (300), said preform being impregnated with resin; polymerizing the resin with a matrix so as to obtain an airfoil element made of composite material comprising fiber reinforcement densified by a matrix; and fastening metal reinforcement on the composite material airfoil element, the metal reinforcement being fastened on the airfoil element by rivets.

The method further comprises, prior to impregnating the fiber preform (300) with resin, inserting spacer elements (10) between the fibers of the fiber preform (300) and removing said spacer elements after the resin has been polymerized so as to form at least one passage between the fibers of the fiber reinforcement of the composite material airfoil element.

Compound structure made of composite material, such as fiber-reinforced polymer resin, comprising first oblong elements reciprocally distanced and parallel to each other and second oblong elements reciprocally distanced, parallel to each other and crisscrossed with respect to the first oblong elements. The first oblong elements and the second oblong elements are made in a single body to define a reticular structure with a monolithic flat shape
