Title: Tear-off metal bottle caps - are locally annealed by induction heating in inert atmosphere after application of lacquer
Inventor: SUPIK HELMUTH DIPL ING
IPC: B21D51/44
Filed: 1980-01-12
Abstract: Tear-off metal caps for bottles etc are made by stamping out discs from sheet metal and then forming a channel section groove around the periphery. In order to ensure a good seal with the bottle the surface of the cap inside the groove is coated with lacquer which may be applied to the metal before the discs are formed. The caps are annealed locally in the region of the groove by induction heating in an inert atmosphere such as nitrogen so that the lacquer coating is not oxidised. This local softening of the metal ensures a good contact with the bottle.

The advantage of this rotor is that wind can be captured with very large surfaces and converted into power.
Patent DE-3102673-A1 (DE)
Title: Lath-like light-screen element for the partial covering of country traffic routes
Inventor: RIEHLE HARALD DIPL ING
IPC: E01F8/00
Filed: 1981-01-28
Abstract: Recently, tunnels with added daylight screens or pure daylight screens have often been arranged over traffic routes for noise-prevention reasons. When the noise-prevention requirements are more stringent, the daylight-screen elements are covered with sound-absorbing material, such as mineral wool, but this damps only the high-frequency fraction of the traffic noise and is therefore effective to only a limited extent. According to the invention, by the additional arrangement of at least two separate cavities which are located one above the other in the element plane and which have orifices perpendicular to the element plane and are coordinated in size with two low frequencies in order to obtain a resonance effect, even low-frequency fractions of the traffic noise are damped and therefore higher noise-prevention effects are achieved. The drawing shows the cross-section of a road (2) having lateral supporting walls (1), on which are mounted crossmembers (3), in which daylight-screen elements (4) according to the invention are suspended parallel to the road axis. <IMAGE>

Patent DE-3112536-A1 (DE)
Title: Heating installation for room heating and/or hot-water preparation with a heat pump
Inventor: ANGER HANS JOHANN GEORG
IPC: F28D20/00
Filed: 1981-03-30
Abstract: The invention relates to a heating installation for room heating and/or hot-water preparation with a heat pump, in which the intermediate heat transfer medium for the heat for evaporating the coolant is air which is extracted from existing ducts laid in the earth, such as waste water, outgoing air, heating, cable ducts, or specially made cavity systems. In such an arrangement, in which the air which serves as heat transfer medium for the heat pump is extracted from existing ducts, the disadvantage arises that as a result of the fact that the air extracted from the ducts and consequently the outgoing air also often contains components which are a smell nuisance or harmful to health and by which an inadmissible pollution of the environment is caused so that the operation of such an installation is impossible unless very expensive mechanical outgoing-air cleaning devices are used. The aim of the invention is to provide an improved heating installation which is designed in such a manner that even air containing components which are a smell nuisance or harmful to health can be extracted from the existing ducts without expensive mechanical outgoing-air cleaning devices being necessary. The aim is achieved by the air extracted as intermediate heat transfer medium from the existing ducts being fed, after heat transfer has been carried out, as outgoing air into a system of ducts laid in the earth. The outgoing air can be fed back into the same ducts or fed into cavities of another existing system or delivered into the atmosphere via a biofilter or via an earth filter. <IMAGE>
Patent DE-3116543-A1 (DE)
Title: Pantograph isolating switch
Inventor: HARTIG ALFRED DR ING
IPC: H01H31/36
Filed: 1981-04-25
Abstract: Pantograph isolating switches are a moving connecting element between two conductor tracks and, as a rule, consist of two lever rods which are connected by means of a connecting joint and can move with respect to one another in the form of a pantograph. They have a static contact pressure and an additional dynamic contact pressure which is generated by the electromagnetic forces of the short-circuit current. Since the short-circuit current is initially very large and subsequently reduces, there is initially a powerful increase in the contact pressure and, subsequently thereto, the components swing back with a severe reduction in the contact pressure which can cause destruction of the contact system. In the pantograph isolating switch according to the invention, the occurrence of dangerous oscillations is prevented in that the current flow is distributed asymmetrically onto the moveable lever rods. Correspondingly constructed moving contact points result in an approximately symmetrical current distribution being ensured in the main contact system itself.
