Patent DE-3501057-A1 (DE)
Title: Drive mechanism for generator without V-belt
Inventor: NORD KLAUS JUERGEN
IPC: F02G5/02
Filed: 1985-01-15
Abstract: In order to overcome the problems of maintenance work, V-belt cracking and discontinuous charging currents occurring in conventionally driven generators, a drive mechanism is described here which utilises the existing energy of the exhaust gases, whilst saving space. In this, a torque, which is transmitted to the generator by way of a shaft, is produced by way of a turbine wheel fitted in the exhaust duct. A centrifugal governor for all consumer units provides for a constant shaft speed. The advantages stemming from this method include improved utilisation of energy, freedom from maintenance, space saving in the engine compartment and constant charging currents.

Title: Method of cleaning and sterilising barrels
IPC: A61L2/20
Filed: 1985-01-24
Abstract: The invention relates to a method and a device for carrying out the method of cleaning and sterilising barrels, especially the interior space of beer barrels (KEGS) made of metal, plastic or a combination of these materials, the barrels having a fitting on a bottom side and an attached riser pipe extending into the interior of the barrel. During this, the barrel is preferably filled at least once with water containing dissolved and/or gaseous ozone, preferably from below, and the ozone-containing water present in the barrel is exposed to ozone gas or ozone-containing gas, the ozone-containing water being expelled after the last filling by ozone gas or ozone-containing gas.   The filling process with ozone-containing water is interrupted at defined time intervals, and exposure to ozone gas or ozone-containing gas takes place in the filling intervals, so that the ozone-containing water already present in the barrel is swirled through by ozone gas or ozone-containing gas. After flushing of the barrel to be sterilised, the ozone-containing water is fed to a processing vessel and then, via an ozone injector, to an enrichment vessel from which it is flushed into the barrel, the ozone-containing gas which is enriched in the enrichment vessel being fed to the barrel via a separate line in a temporally matched manner.

Title: Decentralised current supply by heat/current connection to Stirling engine
Inventor: KRAMER KLAUS ING GRAD
IPC: F24D18/00
Filed: 1985-01-21
Abstract: To improve the utilisation of primary energy, a Stirling engine is operated with an external heat supply in any combustion furnaces, utilising the great temperature gradient between the combustion gases and the forward run temperature of the heating installation, which engine is mechanically connected to a generator, and by these means high-quality electrical energy is generated. This electrical energy is consumed at place of generation or fed into the public electricity network. As a result, the high-loss current generation in large power stations and the line losses at great distances are reduced.

Title: Switching device
Inventor: STEUDEL GOETZ DIPL ING
IPC: H02H11/00
Filed: 1985-04-04
Abstract: In the case of a switching device which is located in the current path between an electrical supply voltage source 3 and a load 1, measures are adopted by means of which the load 1 is connected to the supply voltage source 3 only when the supply voltage for the load is in a defined voltage range. For this purpose, a controllable switching element 6 is connected in the current path, in series with the load 1, which switching element 6 switches the current path through at an upper threshold value of the supply voltage Ue, and interrupts it at a lower threshold of the supply voltage Ua on the load 1. The switching element 6 is in this case controlled by a threshold-value switch. <IMAGE>
Patent DE-3515543-A1 (DE)
Title: Thin-film magnetic disk with structured magnetic storage layer and process for its production
Inventor: BRISKA MARIAN DIPL ING
IPC: G11B5/82
Filed: 1985-04-30
Abstract: The invention relates to a magnetic disk of increased wear resistance and to a process for its production. The magnetic disk (1) comprises a non-magnetic substrate (3) and a magnetic thin film (4) arranged thereupon. Enhanced regions (6) in the form of concentric rings are introduced into the magnetic thin film (4) by local, maskless high-current ion implantation. By a correspondingly adapted dose rate and by introducing the dose in surges per unit area in extremely short times, there forms in the region of the rings (6) a eutectic mixture, the melting temperature of which is rapidly exceeded, which cools rapidly as a consequence of the great temperature gradient and results in the formation of a metal glass. The concentric rings of the metal glass accomplish an adequate level of wear resistance of the surface of the magnetic thin film, so that no coating is required. Because the metal glass is non-magnetic or soft-magnetic, the rings can at the same time bear the servo information for the magnetic disk. <IMAGE>

Title: Circuit arrangement for generating an oscillating switching voltage
Inventor: SCHRADER WERNER DR ING
IPC: H03K3/80
Filed: 1985-07-17
Abstract: The invention relates to a circuit arrangement for generating an oscillating switching voltage for high-voltage test engineering. The invention has the object of creating a circuit arrangement for generating switching voltage, the voltage variation being symmetrical with respect to the zero line and being effected by means of a high-voltage test transformer, via the low-voltage winding of which a capacitor is discharged and the overvoltage winding of which is loaded with a device under test. According to the invention, the object is achieved by the fact that a switching element, for example a thyristor switch which is located parallel to the undervoltage winding short-circuits the latter at the instant at which the current in the primary winding has its first zero transition, as a result of which a series resonant circuit is formed. The shape of the oscillation can be changed by connecting inductors and resistors into this circuit.

Patent DE-3620475-A1 (DE)
Title: Combined hydromechanical overload protection and lift-out device for ground-working implements
Inventor: SCHWOPE REINHARD DIPL ING
IPC: A01B61/00
Filed: 1986-06-19
Abstract: The invention relates to the combination of an overload protection and a lift-out device for ground-working implements consisting of hydraulic and mechanical components. A known overload protection has a toggle-lever system which absorbs the working pressure of the implement and which buckles in the event of overload. A hydraulic cylinder presses the implement back into the ground with the full working pressure immediately after the upper end position of the implement has been reached. The implement does not remain in the upper position and also does not reach this until it is lifted out completely by the obstacle. Where smaller obstacles are concerned, this device does not fulfil its operating capacity. The proposed solution eliminates these disadvantages. The toggle-lever system 5, 7, 9 is equipped with a rocker lever 7 which is under spring pressure. Connected to the rocker lever 7 is a smaller hydraulic cylinder 14, by means of which the rocker lever 7 can be pivoted. During pivoting, the rocker lever 7 overturns as a result of the change of torque generated by the spring 11 and brings the implement 1 from one end position into the other end position. <IMAGE>
