Title: Automatic three=phase centrifugal separator - with sludge discharge periodically actuated by sludge accumulation
Inventor: TANAKA YASUHISA
IPC: B04B1/18
Filed: 1976-09-30
Abstract: An automatic centrifugal separator for three-phase mixts. such as heating or motor fuel oil contg. sludge and water droplets includes a sludge outlet which is controlled by a valve cylinder. A first water pressure chamber shuts the latter, and a second water pressure chamber opens it. Blockage of the water discharge by sludge accumulation causes the water to flow into a third chamber. This gives access for water from a fourth chamber to the second to open the sludge discharge. Water drainage causes water from a fifth chamber to enter the first and close the valve cylinder. This discharges the sludge automatically at periodic intervals and is more accurate than any empirical manual discharge. Blockages of discharge nozzles are eliminated.

Title: Lining for mine galleries - comprises wire mat backed with thermoplastic film bags which are filled with foamed polyurethane
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1976-10-14
Abstract: In mines and tunnels, the lining of a gallery is attached to the surrounding rock with a cold-setting filling, using a covered wire mat and a backing to prevent the filling from penetrating the space formed before that filling is applied and cured. The backing is produced in applying the covered wire mats and using bags of the same size as a mat, and the filling is introduced into the bags which are applied to the rock during filling and/or whilst the filling cures. Provides uniform contact of lining with the rock, and higher degree of mechanisation than earlier systems; enables polyurethane resins to be used, saves one operation by incorporating backing with the wire mat, and dispenses with application of filling to the rock face. The process is suitable for temporary galleries.

Title: Continuous advance device for tubes during drawing process - uses by two=part clamping jaws on driven endless chain
Inventor: OPPERMANN WILLI
IPC: B21C1/30
Filed: 1978-02-09
Abstract: The tube is transported by sets of two-part clamping jaws with pressure springs fitted between the jaws which tend to force the two jaws apart. The jaws are fitted to an endless chain running over two rollers one of which is driven by an electric motor. When the jaws are travelling in the lower part of the chain, the springs keep the two halves wide open to that the dia. of the tube is allowed to pass through the gap between the two halves, once the jaws rise into the upper section of the chain. During further travel along the upper path of the chain the jaws enter a space between two opposite rows of vertical rollers with such an adjustable gap which forces the two jaw halves to move against each other so that the tube is gripped and carried along. At the end of the row of rollers the narrowed gap ceases and the tube is released. The use of two carriages operating in a shuttle movement is not required.
