Title: Method for the utilisation of waste heat for the generation of mechanical energy
Inventor: FOERSTER HANS DIPL ING
IPC: F25B15/02
Filed: 1981-10-23
Abstract: The invention relates to an improvement of the method for the utilisation of waste heat for the generation of mechanical energy with optional, simultaneous cold production, according to patent application P3101858.0. The method can be used as a downstream process (coupled process) of thermodynamic processes and cyclic processes producing waste heat, the generation of mechanical energy and from this electrical energy being of prime importance and cold production with variable power share being an additional option. The aim of the invention is to improve the utilisation of waste heat according to the main patent whilst an increase of the usable proportion of the waste heat supply results in an efficiency increase in respect of the energy utilisation. According to the invention, this is achieved in that for utilisation of the waste heat a desorption cascade is used in which the waste heat is employed in several stages for the desorption of working substances from enriched solutions. In addition, the hot weak solution is also regeneratively cooled by desorption of working substances. The sphere of application of the invention is in all processes producing waste heat, such as nuclear power plants, chemical plants, drying processes and flue gas generating processes.

Title: Process for producing protective plies for belt replacement in the retreading of vehicle tyres
Inventor: SCHMERMBECK DIETER
IPC: B29C43/00
Filed: 1983-09-16
Abstract: According to a process, protective plies for belt replacement in the retreading of vehicle tyres or for repair patches which are given an internal reinforcement of fibres, for example of glass fibres can be produced. To this end, a fibre quantity of 10-20 % by weight is blended into a rubber compound which is vulcanisable to highly elastic rubber material with a hardness of approximately 70 Shore-A, while the rubber compound is moulded or rolled out in a pressing device, such as for example a roll device, to form sheet material. The unvulcanised protective plies are used instead of damaged and therefore removed belts of tyre carcasses or for belt covering or for stiffening the carcass in the bead region or as starting material for patch production. After vulcanisation in the pressurised chamber at a temperature of approximately 90 DEG C and a pressure of 5 bar, the protective plies have increased tensile strength, a reduction in the elongation as well as an increase in modulus and in rebound resilience.

Title: Implant as substitute for a fallopian tube whose function is disturbed
Inventor: SAYME MOHAMED NAIM DR MED
IPC: A61B17/435
Filed: 1983-11-30
Abstract: The implant is a hollow body 1 subdivided into a capsule 3 and a tubular outlet 2 which serves as substitute for a fallopian tube whose function is disturbed. The capsule 3 has a passage opening 6 through which the ovary 4 belonging to the disturbed fallopian tube is inserted in the interior of the capsule. Inside the capsule it is retained by a suitable mounting. The passage opening 6 is sealed except for a passage for the supply thread 5 connected to this ovary after insertion of the ovary 4. In the region of the inlet opening 15 of the fallopian tube whose function is disturbed the tubular outlet 2 is connected to the interior of the uterus 20. In the inserted state, the capsule 3 catches the mature egg cells supplied by the ovary 4 and guides them towards the outlet where they are fertilised and may remain before they finally reach the uterus. In principle, the capsule 3 thus takes over the function of the funnel-shaped entrance to the fallopian tube and the tubular outlet 2 correspondingly assumes the function of the actual fallopian tube, so that the implant simulates the entire correct function of the natural fallopian tube. <IMAGE>
