Patent DE-4004005-A1 (DE)
Inventor: IWAKO MOTONARI
IPC: B65G65/48
Filed: 1990-02-09
Abstract: A particulate material feeder includes a hopper (1) sectioned into two receptacles (2, 3) for accommodating two different kinds of particulate materials. Each particulate material falling down through a bottom opening (5, 6) of the receptacle is introduced into a feed channel defined between a feed roller (8, 9) having a frictional periphery and a control gate (10, 11) having a semi-circular cross-section. An opening degree of the feed channel may be controlled separately and independently in each feeding system so that a predetermined mixing rate of the two kinds is obtainable as desired. The feed rollers provided in each feed system are driven by a single driving source to rotate at the same speed. One of the receptacles may further be divided into subsections for accommodating additional kinds of particulate materials such as additives. <IMAGE>

Title: Cleaning of ground contaminated by oil from tankers - using mobile burning equipment which is easier, quicker and cheaper
Inventor: OEY SWAN TJIN DR ING
IPC: B09C1/06
Filed: 1990-04-06
Abstract: In this system of cleaning ground contaminated with oil, the surface of the ground is, without mechanical disturbance, heated up to the combustion temp. of the oil. Variants claimed include the use of one or more burners that are continuously or discontinuously moved over the ground. A number of variants are claimed for the equipment that can be used. USE/ADVANTAGE - The system can be used in coastal areas contaminated by oil from tanker accidents or spillages. Removal of such contamination manually is slow and laborious work, and neutralising the oil chemically also involves problems. The proposed system, which can also be used on contaminated ground inland, is easier, cheaper and quicker than manual clearance, and also solves the problem of sludge disposal.

Title: Cutting segment - has notches filled with diamond grains embedded in matrix material
Inventor: HEYKES JUERGEN
IPC: B28D1/12
Filed: 1991-06-24
Abstract: The cutting segment for a tool or drill, with embedded diamond grains,  has notches across the cutting direction to contain the tightly packed diamond grains embedded in a matrix material. The notches pref. run at right angles to the surface of the cutting segment, or they can be angled forwards in the cutting direction. The diamond grains are pref. wholly within the notches. The base material of the cutting segment, where the notches are pref. formed, is of a softer material than the matrix for embedding the diamond grains. The notch width is 2-3 times the mean grain size of the diamond material and recesses between the notches are wider than the notches. ADVANTAGE - The cutting segment gives the balance between wear on the tool material and the availability of fresh diamond material, so that the tool always presents a precise cutting surface.
