Abstract: A portable continual mixer blends dry powdered material with an aggregate and a liquid. The ingredients may be cement, sand, and water. The batch mixer has two screw augers. The first auger feeds dry mix into an elongated mixing chamber, and has its own electric motor and speed control. The second auger mixes the dry and liquid mix constituents, and conducts blended mixture to a discharge port located at the end of the elongated mixing chamber. The blade of the second auger is formed in three sections. In respective order, these sections include a first section wherein the blade is configured as a screw auger; a second section wherein the blade has paddles pitched to urge the mixture onward to the third section; and a third section which, like the first section, includes a blade configured as a screw auger. The liquid is metered by a valve controlled in accordance with the feed rate of the solid constituents. A predetermined proportion of dry and liquid constituents is thus maintained.

Abstract: An improved brewing pot is disclosed that allows the user to stop the brewing process at the point where the decoction is at the desired strength. In the preferred embodiment, the material from which a decoction is to be made is placed in a cylindrical chamber, boiling water is added, and then a circular screen carrying member, wherein the carried screen is exposed in pie shaped slots, is lowered into the chamber to approximately the level of the brewing liquid. When the brew has reached the desired strength, the screen carrying member is lowered into the liquid. The screen member is surrounded by a flexible gasket and the exposed portions of the screen itself are of sufficiently fine mesh so as to segregate the steeping material from the brewed or decanting area. The screen portions are then closed off, preventing fluid communication between the decanting chamber containing the finished brew, and the smaller area containing the brewed material, along with some amount of water.
