Title: Temp. change stable cable - uses load-bearing elements and bonding agent, with thermal reactions giving controlled cable length as temp. changes
Inventor: SNELLMAN DONALD L
IPC: D07B1/00
Filed: 1978-04-27
Abstract: The bonding agent has a radial expansion action on the application of heat, and is provided in a sufficient volume for the load-bearing elements that the total cable length change can be controlled as temps. rise and fall. This is achieved by applying the action of outer surface area change at the same time as length changes. The load-bearing elements (4) are wound in a spiral at a constant angle (x) where kB and ks are the linear expansion coefficients of the bonding and the reinforcement, and B is % vol. of bonding agent. The design gives a cable which, on temp. changes, either stretches, contracts, or maintains a constant length. Typically the cable consists of glass fibre bundles embedded in an elastomeric material, the latter having the larger linear coefficient of thermal expansion.

Title: Insulated sheathing of e.g. silane-grafted polyethylene - is prepd. using an extruder worm with sintered porous segments admitting moisture
Inventor: VOIGT HERMANN-UWE DIPL CHEM DR
IPC: B29C48/06
Filed: 1978-06-23
Abstract: The amt. of moisture necessary for the grafting of a silane cpd. onto the molecules of thermoplastics, elastomers or thermoplastic rubbers, is introduced in the vapour phase whilst pressure builds up for the extrusion of the material, to form an insulating sheath on objects of extensive length, such as electrical cables or pipes. This makes possible the efficient supply of water necessary, esp. in the case of cables to accommodate the very highest tension without the introduction of impurities which degrade the electrical characteristics of the insulation. The arrangement puts in the water in a short time, the quantity and its fine division being such that when subjected to normal pressure, the water remains dissolved in the hardened mass.

Title: Open cycle gas turbine engine - has water and fuel injected in stages to give isothermal compression and expansion
Inventor: MUCIC VINKO DIPL ING
IPC: F02C7/143
Filed: 1979-06-21
Abstract: Air (21) enters the compressor and is compressed adiabatically in the first stage (3). It then passes through a set of compressor stages (4) in which water (6) is continuously injected to give isothermal compression. This is followed by a final stage (5) of adiabatic compression. The mixture of compressed air and steam enters an expander. In the first section (14) of this combustion takes place in stator sections of increasing volume. Fuel (8) is injected throughout the stages as the gases expand so that there is an isothermal expansion. This is followed by an adiabatic expansion (15) and finally the gases are discharged (23) at a higher temperature than the intake.

Abstract: A circuit breaker having stationary contactors provided for all of the poles thereof. Movable contactors are provided for all of the poles in correspondence to the stationary contactors. Stationary contacts are provided on the end portions of stationary contactors and movable contacts are disposed on the end portions of the movable contactors. The movable contactors are movable from the stationary contactors by electromagnetic force to open respective circuits before the circuit breaker is opened by an overcurrent tripping device when large current such as short-circuit current flows. Holders adapted to hold the movable contactors of all of the poles are mounted on a common rotatable insulating rod, one of the holders being provided with a latch which is turnable around a rod provided on the holder. A slot is normally engaged with the latch, and when disengaged from the latch, a rod can be turned by the holder. A spring operates to engage the latch with the rod until an electromagnetic moment acting on the latch generated in any of the poles or the sum of electromagnetic forces generated in all of the poles reaches a predetermined value. When a predetermined value is exceeded, the movable contactors of all of the poles are simultaneously moved from the stationary contactors to open the respective circuits with the aid of the insulating rod and the holders.

Title: Halbleiterlaser
Inventor: MARSCHALL PETER ING GRAD
IPC: H01S5/00
Filed: 1979-08-16
Abstract: Durch die Aufteilung der laseraktiven Zone in mindestens drei Schichten, derart, dass die Schicht mit dem kleinsten Bandabstand von Schichten mit groesserem Bandabstand umgeben ist und sich ein PN-Uebergang unmittelbar an der Schicht mit dem kleinsten Bandabstand befindet, erfolgt die Rekombination der Ladungstraeger und damit die Erzeugung des Laserlichtes im wesentlichen nur in der Schicht mit dem kleinsten Bandabstand. Das optische Feld wird dagegen in der gesamten laseraktiven Zone gefuehrt. Die Diffusion eines streifenfoermigen Leitfaehigkeitspfades ist jedoch nicht bis in die Schicht mit dem kleinsten Bandabstand hinein durchgefuehrt, sondern endet in der Schicht vorher. Dadurch wird das optische Feld in gewuenschter Weise seitlich gefuehrt und die Diffusion bewirkt keinen stoerenden Einfluss auf die Rekombination in der Schicht mit dem kleinsten Bandabstand und damit auf die Erzeugung der Laserwelle und die Lebensdauer des Lasers. Es wird eine verbesserte spektrale einwellige Emission auch bei Temperaturunterschieden des Lasers erreicht.                                                                                                                                                                                                                                                                                                                                                                                                                                             ...U.S.W
