Title: Power system exploiting geothermal heat - has refrigerant evaporator deep in earth with condenser near surface and uses liq. return to drive turbine
Inventor: VELDUNG ERWIN
IPC: F03G4/00
Filed: 1979-05-04
Abstract: A shaft is dug in the earth and an evaporator is placed at the bottom of it at a depth where there is a constant high temp. A refrigerant is evaporated in this and the vapour drives a turbine coupled to a generator. The exhaust from the turbine is condensed by near atmospheric temperatures in a condenser just below the earth's surface. The resulting liq. is returned to the evaporator at the bottom of the shaft through an insulated pipe. The returning liq. passes through a turbine at low level in the shaft. The shaft depth is thus utilised for additional energy production.

Title: Open=end spinning between contra-rotating drum surfaces - having increasing separation between yarn-formation line and plane of narrowest gap
Inventor: TURK HERBERT
IPC: D01H4/16
Filed: 1980-03-06
Abstract: In an open-end spinning device wherein the yarn is formed in a narrow gap between two counter-rotating surfaces through which a fibre-transport air-flow is created by internal suction devices, the mouths of the suction devices are so inclined to the cross-sectional plane of the narrowest part of the gap that the separation of that plane and the plane of yarn formation gradually increases in the direction of yarn withdrawal. The line of intersection of the two planes is located in the vicinity of the open end of the thread, and, at its narrowest point, the gap between the rollers has a width of less than 50%, and preferably less than 30%, of the diameter of the spun yarn. The widening gap gives an increase in yarn quality of more than 30%, and the proposed arrangement provides a relative simple means of adjusting and maintaining the required gap geometry without demanding impractically high precision in the construction of the device.
