Abstract: A method for the manufacture of a high alumina hydraulic binder comprising hydrating a source of aluminium ions with a source of calcium ions in the presence of water to form mineral hydrates and subsequently heating said mineral hydrates to form said high alumina hydraulic binder.

Abstract: The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line or localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.

Abstract: A lower receiver assembly of a rifle including a lower receiver having a magazine well formed thereon between a distal end and a proximal end, the lower receiver operable to receive a trigger assembly including a trigger, a hammer, and a firing pin. The lower receiver can include an operating rod retention tab coupled with an upper surface of the receiver and the operating rod retention tab extends above the upper surface and is operable to be received in a groove formed in a receiver of an upper receiver.

Abstract: The present invention relates to inserts for hard facing substrates, and a method for hard facing substrates. An insert according to an embodiment of the present invention may comprise a body of ultra-hard material having a welding node located on a first surface thereof and at least one wire electrically connecting the first surface to a second, opposite, surface. In use, the inserts may be temporarily connected to a substrate by applying a resistance welding electrode to the welding node, thereby causing the wires on the second surface to melt and weld the insert to the substrate. A subsequent brazing step may firmly attach the inserts to the substrate.

Abstract: Spherical projectiles may be used to form one or more holes in geologic or other material. These holes may be used for drilling, tunnel boring, excavation, and so forth.

Abstract: A refrigerator has a cabinet. The cabinet has an opening therein to provide access to the cabinet. The opening is defined by a frame forming a face of the cabinet about the opening. The frame has a first face corner, a second face corner, a third face corner and a fourth corner; each face corner having a respective securing means thereon. A door has a first edge. A first recess is formed at an end portion of the first edge. A second recessed corner is disposed at a second end point of the first edge; away from the first corner. A first hinge is disposed in the first recess. A second hinge is disposed in the second recess. The door is hingedly affixed to the cabinet for selectively sealing the cabinet when the first hinge is affixed to one of the securing means of the first corner and the second corner, and the second hinge is affixed to one of the securing means of the second corner and third corner.
