Patent DE-3415957-A1 (DE)
Title: Keyed joint for channel sections in underground roadway support
Inventor: MEYER WILLI
IPC: E21D11/22
Filed: 1984-04-28
Abstract: Amongst experts the clearly held view is that, in the case of yielding support, a keyed joint functioning as a clamping joint is always to be preferred to a screwed joint as a quick-acting lock. For example: Quick and simple assembly, safe dismantling, easy control of the joint by striking the joining key again, clearly arranged stock-keeping. The keyed joints known hitherto have not been able to gain acceptance in practice due to unfavourable bearing conditions and thus poor working of the joint. Therefore, a large number of all clamping joints are equipped as screwed joints. With the recognition of the requirements for an effectively working joint, the screwed joint is replaced by the redesign of this keyed joint. Here, it is especially important that the key fits tightly in a variable manner on its base after tightening and that the joint experiences an additional load increase during retraction of the support by the purely physical lever principles mentioned in the description.
Patent DE-3421372-A1 (DE)
Title: Dryer for shoes and in particular boots with long shafts
Inventor: EGGENSBERGER FRANZ
IPC: A43D3/14
Filed: 1984-06-08
Abstract: For more rapid, more protective and more convenient drying of shoes and boots, the dryer is equipped with nozzle pipes which extend as far as the boot toes and through which an air flow generated by a blower and guided via heating elements can circulate as far as into the toes. The moisture evaporating in this connection is forcibly carried away by the air flow flowing out of the shaft. As a result, a rapid, uniform drying which protects the shoe material takes place not only in the case of leather shoes but also in the case of rubber, plastic and ski boots. In order to be able further to increase the drying effect, an additional outer casing is envisaged, which forces the hot air flow energing from the shaft to flow around the outer surface of the shoe. In order that the device is easy to stow or can be taken along when travelling, it is designed in such a manner that it can be transformed into a small and handy unit by removable or fold-in nozzle pipes.

Patent DE-3507856-A1 (DE)
Title: Turbine internal combustion engine
Inventor: UHLITZ KURT
IPC: F02C5/12
Filed: 1985-03-06
Abstract: Like conventional internal combustion engines, the turbine internal combustion engine is driven by the combustion of a fuel mixture. The combustion energy, however, directly drives a turbine 10 in a rotational movement. Crucial in this is the fact that due to the combustion of the fuel mixture in a closed combustion chamber 4 a potential energy is built up. This is converted into kinetic energy only once the combustion chamber 4 has opened. The combustion gases thereby flow through the exhaust port 9 into the turbine 10 and drive the latter. The fresh air is compressed by a turbocharger 1. This is arranged upstream of the combustion chambers. The inlet and exhaust gases are controlled by control discs 3 and 7. The cycle is therefore as follows:     Compression in the turbocharger 1 Inlet into the combustion chamber through the aperture 2 by means of the control disc 3   Closing of the combustion chamber 4 by the control disc 3   Injection of the fuel through injection nozzle 5   Ignition by spark plug 6 and combustion Opening of the exhaust aperture 9 by control disc 7 for inlet of the combustion gases into the turbine 10 Then closing of the combustion chamber 4 by control disc 7 and repeated cycle.   <IMAGE>
