Title: Optical wave guide - for information transmission with spead optical conductors bonded to a film support held in a shorter corrugated metal tube
Inventor: STRICKER GUENTER
IPC: G02B6/44
Filed: 1975-04-30
Abstract: In the production of an optical cable for information transmission consisting of a number of transmission elements combined with tension-resistant elements and surrounded by a metal sheath, in which single or multiple optical transmission elements are only spot-bonded to the tension-resistant elements at predetermined intervals and their length is somewhat greater than that of the tension-resistant elements, as disclosed in the parent application, (a) the optical transmission elements are placed on one or more films and point-fixed to at least one film at predetermined distances, the films being cut in the transverse direction in such a way that they have lugs of normal width projecting on both sides at constant intervals (b) the so-formed films with the optical elements bonded thereto are introduced into a tubular sheet fabricated from a metal strip, which is subsequently corrugated in a corrugating machine in such a way that the film lugs engage corrugation in the corrugated metal tube, the corrugations and film projection spacing being so dimensioned that a certain excess length of the optical transmission elements results relative to the corrugated tube. Ensures that the tension-resistant elements accept the tensile stresses rather than the optical transmitting cable.

Title: Evaporation of liquefied natural gas in power stations - using cooling water to provide heat for evaporation
Inventor: KOZLOW WLADIMIR BORISOWITSCH
IPC: F28B9/06
Filed: 1976-01-30
Abstract: An arrangement for vaporising liquefied natural gas in a power station is equipped with gas-fired boilers, steam turbines and a condenser cooled by recirculated water. A storage tank is provided for the liquefied natural gas, which is evaporated in stages and delivered to the boilers during periods when the supply of gas from a normal supply pipe is inadequate. The improvement is that the fluid stage in the evapn. of the gas takes place in a heat exchanger in which the heat is provided by the condenser cooling water. The thermal efficiency of the tower station is increased by utilising heat normally wasted in a cooling tower. The cooling tower duty is correspondingly reduced and the effect of the cooling tower on the environment is reduced. Additional electrical power can be generated by a subsidiary turbine in which a refrigerant is expanded. The refrigerant is condensed in the first stage of the liquefied natural gas evapn. process.
