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 retaining wall having a plurality of courses of retaining wall blocks including a first upper course and a second lower course. Each retaining wall block has opposed front and rear faces, opposed first and second side surfaces, and opposed and substantially parallel upper and lower surfaces, and at least one weight bearing pad extends from one of the upper and lower surfaces. The at least one weight bearing pad extends substantially from the rear face to the front face of the block. The weight bearing pads are the only areas of contact between the blocks in the first upper course and the blocks in the second lower course.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

A device for producing dental ceramic, with a CAD/CAM device for preparing a compression molding cavity for producing the dental ceramic, wherein a CAD device thereof, on the basis of scan data, determines the shape of the dental ceramic to be produced, and wherein a CAM device thereof produces a positive model, on the basis of which the mold cavity is produced via a sacrificial mold (muffle). The CAM device also determines the distribution and the transfer between different ceramic types, i.e. types of ceramics that differ at least in respect of one parameter in terms of material, appearance, strength or the like, wherein the CAM device for adjusting the distribution and the transfer determines the position and the dimensions of a feed channel between a muffle rod and the compression molding cavity for producing the dental ceramic according to at least one of these parameters.

The present disclosure generally pertains to blocks for building landscape walls and similar structures, the molds used to make the blocks, and the methods for making the blocks. Such block can be securely coupled to another block. A block can be vertically coupled to another block by coupling the dorsal face of one block to the ventral face of another block. The block can be horizontally coupled by coupling the male side of one block to the female side of another block. A secure, exemplary landscape wall may be created by coupling the blocks both horizontally and vertically to reach a desired height, width, and shape.

A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.

A mold for making dry cast concrete blocks includes a pair of vertical shoulder forming sections, one along each of the opposite sides of the mold to form vertical front shoulders of a block. Each shoulder forming section has a shoulder roughening arrangement to result in molded, roughened shoulders of the block. Methods of making such blocks and the resulting block are included.

Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.

A method and mold assembly for forming a dry cast concrete corner blocks having non-parallel front and rear faces and non-parallel end faces, with a hollow central core in the blocks. The corner blocks can be used to build a square or irregular corner in a retaining wall, and can be used to build columns or pillars in the wall, without having to cut the corner blocks. Fill material may be poured into aligned cores in the stacked corner blocks which form the wall corner or column, to stabilize the corner blocks.
