The appearance of natural rock faces are formed on planar panels or part portions disposed horizontally by stamping or texturizing a cementatious mixture of veneer material and then selectively applying colorant matter, which may include combinations of stains and mineral.

A mold assembly and method for molding two concrete blocks in face-to-face non-contacting relationship forms blocks having smooth front faces. The mold assembly includes a mold box having two mold cavities configured to form two blocks in face-to-face non-contacting relationship. A common partition plate separates the two mold cavities and opposite sides of the partition plate form the smooth front faces of the blocks. The two mold cavities are each configured to form a block having a raised front face with a beveled edge around its entire perimeter and a border around the entire perimeter of the beveled edge. The portions of the border at the top and the sides of the raised front face are curved and the portion of the border at the bottom of the raised front face is straight. A core bar is slidably inserted into the mold box beneath the bottom of the partition plate, and opposite sides of the core bar extend into and form the front bottom portions of the mold cavities.

A monolithic airflow testing mold suitable for mating with a workpiece includes a platform portion formed from a first material having a first hardness. The mold further includes a workpiece mating portion surrounding by the platform portion. The mating portion includes a support region abutting the platform portion and formed from a second material having a second hardness, and a sealing surface positioned above the support region and formed from a third material having a third hardness. The sealing surface is configured to mate with and extend into a hollow portion of the workpiece. The first hardness is different from at least one of the second and third hardnesses.

A method for attaching a first object to one or more second objects of dissimilar materials, without any bonding material, using a molded attachment block is provided. Anchoring grooves are created and a constrained assembly is positioned at opposing sections on a surface of the first object. A tension is generated in tension bearing members anchored in the anchoring grooves and extended along a length of the constrained assembly. The constrained assembly is constricted between mold side members positioned perpendicular to the mold end members. The tension bearing members are clamped between bolt assemblies. A viscous liquid is poured and cured on the constrained assembly, the tension bearing members, the anchoring grooves, and the bolt assemblies for creating the molded attachment block with opposing ends of the threaded members of the constrained assembly extending outwardly from the molded attachment block for attachment to second objects without any bonding material.

A method of forming a ceramic component is disclosed. A ceramic matrix material is combined with a binder material. The ceramic matrix material and the binder material are mixed to create an intermediate slurry. After mixing the ceramic matrix material and the binder material, reinforcing fibers are added to the intermediate slurry to create a final slurry. The final slurry is introduced into a mold cavity having a shape corresponding to the ceramic component. The final slurry is at least partially cured within the mold cavity to form an intermediate casting. The intermediate casting is sintered to produce the ceramic component from the intermediate casting.

A concrete mat apparatus, includes a plurality of elongated concrete members, each member being aligned with and next to another concrete member. Each of the concrete members has an upper generally flat surface, a lower generally flat surface, and a plurality of inclined surfaces that each extend away from an upper or lower surface. Reinforcement extends from a first end portion of each concrete member to a second end portion thereof, the reinforcement including a plurality of longitudinally extending reinforcement bars and a plurality of encircling tie bars at spaced apart intervals. Cabling connects each of the elongated concrete members to another of the elongated concrete members. The upper inclined surfaces of one of the elongated concrete members forms a plane with the lower inclined surface of an adjacent elongated concrete member. A plurality of loops are provided along opposed edges of the mat.

The present disclosure is generally directed to processes and apparatuses for use in forming one or more flow channels within a prefabricated manhole assembly. More specifically, an exemplary apparatus embodying various aspects of the disclosure may contain a rigid channel form with a closed top portion, a curved bottom portion, a first end, and a second end. The apparatus may also contain a bung(s) removably positioned into an exterior hole through a sidewall of the prefabricated manhole that may receive one end of the channel form, the bung(s) interior end may further have an open-ended U-shaped slot. A sliding wedge may be used to engaged/disengage the flow channel form.

A formwork for providing a plinth with concrete frame and with exposed horizontal reinforcing bars, is disclosed. The framework has a base the shape of which in plan view corresponds to the concrete frame. Each side of the base is provided with inner and outer lateral containment walls which extend vertically from the base to make a casting chamber for the concrete. The inner walls have a plurality of openings for the insertion from above of a plurality of longitudinal reinforcing bars. At least one of the outer walls is provided with a plurality of openings for the insertion by transverse sliding of a plurality of transverse reinforcing bars. The openings are provided with inflatable elements which are configured to transition from a deflated configuration, in which the bars can freely slide in the openings, to an inflated configuration, in which the bars are locked in position. The chamber is watertight in order to prevent concrete from coming out during casting.

The invention is directed to a process for producing a cured 3D product comprising the following steps: (a) providing a form negative mould of the 3D product comprising of one or two formed plastic sheets as obtained by thermoforming corresponding with the shape of the 3D product; (b) adding a liquid curable composition to the mould such that the inner surface of the mould is covered by the curable composition; and (c) solidifying the curable composition wherein a solidified layer or body is formed having the shape of the 3D product; wherein the cured 3D product is a radiation cured 3D product; and wherein the step (c) a radiation curable composition is solidified by radiation through the plastic sheet of the mould to form a solidified layer having the shape of the 3D product.

An articulating composite surface covering mat and process of forming the mat are provided. The mat has multiple units having a regular, natural or irregular appearance, and each unit a flexible geogrid extending therethrough. Gaps are formed in the spacing between the units. A method of forming the mat includes forming the mat upside-down on a bottom surface of a bottom mold, locating a geogrid in a cavity defined between either or both of the bottom mold and a top mold, and placing the top mold over the bottom mold to form the mold assembly, sealingly engaging the transverse walls of the bottom mold and top mold where there is no geogrid, and adding the filler to the mold assembly.
