Title: External combustion rotary engine or pump for liquids or gases - with a rotating blade, eccentric sleeve and common lubricant system
Inventor: BOLENKO ANATOLIJ
IPC: F02G3/00
Filed: 1976-01-16
Abstract: Rotary engine usable as an external combustion engine or as a pump for liquids or gases comprises two cylindrical working chambers, axially separate but with a common shaft. Rectangular protrusions on the shaft, set 180 deg. apart, sweep their respective chamber wall as the shaft rotates. Coolant passages in the shaft connect with the hollow inside of the protrusions. a cylindrical sleeve, eccentrically mounted to be in contact with the shaft on the inside and the chamber on the outside, rotates with the protrusion and seals against its faces, creating variable volume spaces both inside and outside it. The cyclic volume variation of the spaces on the outside of the sleeve is used to compress air for supply to the separate combustion chamber, and to allow products of combustion from this chamber to expand and drive the engine. The volume variation of the spaces inside the sleeve is used to pre-compress some of the charge, induced through an entry port and fed into an outside chamber through a transfer port with a non-return valve.

Title: Three phase HV cable system - uses three wires in parallel with discrete cables having central water coolant station
Inventor: BRAKELMANN HEINR DR ING
IPC: H01B7/42
Filed: 1976-02-27
Abstract: Three-phase electric current cable system for water-cooled high power cables consists of three parallel laid wires of discrete cables. The coolant medium travels through a cooling station connected to the wires. To reduce erection costs without significantly reducing the power transmission capability of the proposed system compared with a system having feed-back tubes or pipes, the cooling station is installed at the centre of the cable wiring system so that the latter is divided into two-sub-systems having equal lengths of cable. The coolant inflow is carried out through two cable wires, with the feedback or return being completed via the third cable wire. More specific inflow is taken via the two outer lying wires and the return flow via the centre wire.
