Patent DE-3133575-A1 (DE)
Title: Gas generation process
Inventor: BROTZMANN KARL DR ING
IPC: C21B13/00
Filed: 1981-08-25
Abstract: The invention relates to a process for generating gas from carbonaceous fuels in a iron bath reactor. According to the teaching of the parent application P 3,031,680.4, the gases generated in the molten iron of the reactor are extracted in the reactor space above the melt by oxygen blown onto the bath surface of the iron bath reactor, entrained to the bath surface and partially burned, the heat generated being transferred to the molten iron. According to the invention, molten iron (crude iron) is additionally produced simultaneously with the gas generation, by feeding iron, at least partially in the oxide form, for example as ore, to the iron bath reactor. In a further development of the invention, it is proposed to utilise the coal gas generated in the iron bath reactor for the prereduction of ores and to feed the thus prereduced ores to the iron bath reactor for the production of iron.
Patent DE-3133756-A1 (DE)
Title: Double-pipe (tube-in-tube) cooler
Inventor: MARTIN HANS DIPL ING
IPC: F28D7/10
Filed: 1981-08-26
Abstract: The invention provides a description of a double-pipe cooler which consists of at least one double pipe, preferably made from aluminium, which is constructed from two pipes arranged concentrically in one another and on whose end regions there are arranged distributor stubs which have a neck with a feed duct extending perpendicularly to the pipe axes and via which the oil or the like which is to be cooled is fed to or extracted from the double pipe. According to the invention, it is provided that the distributor stub is constructed as a sealing stopper which can be mounted coaxially with the cylindrical connecting regions on the ends of the inner and outer pipes which form the double pipe, and is provided with a chamber which is connected to the feed duct and is situated between the connecting regions for the pipes. The advantages of the invention reside in that the distributor stub of the type of a sealing stopper need only be used plugged over the end regions of the double pipe and is held securely there, with the result that there is no longer any need to weld the inner and outer pipes forming the double pipe. In addition, the distributor stub itself need no longer be soldered or welded to the outer pipe for the purpose of axial securement. As a result, it is possible to use aluminium pipes, e.g. for the double pipe, which permit the implementation of high heat exchanger efficiencies.

Title: Method and blank for the production of a compensator bellows
Inventor: FORTMANN MANFRED ING GRAD
IPC: F17D5/02
Filed: 1981-09-24
Abstract: In multi-layer compensator bellows with individual layers (1, 2) held apart by spacers (3), the spacers are first of all placed in their full length between the layers and the said layers are deformed in the customary manner to give the finished bellows. If spacers at one or both ends need to be shortened in order to provide transitions from one to the other of the interspaces remaining between them, the corresponding ends of the spacers are then torn off. To facilitate tearing off, the spacers (3) are provided with predetermined breaking points (5, 6). <IMAGE>

Title: Arrangement for unloading and loading drawing cages at a shaft
Inventor: STRATMANN KLAUS ING GRAD
IPC: B66B17/20
Filed: 1981-10-03
Abstract: The invention relates to an arrangement for loading and unloading drawing cages at a shaft, in particular at a blind shaft, of underground mining operations. The arrangement includes first of all a feed track for mine cars which leads in an allocated roadway to a shaft door, an exiting track for mine cars, and a driven, self-propelled manipulating car with a pivotable and if need be retractable and extendable crane arm. Located on the latter is a manipulator for the material to be manipulated. The manipulating car can be moved on a track. An intermediate storage rack unit is arranged at a distance from the shaft door, which distance is several times, for example twice, the length of the manipulating car, next to the track on which the manipulating car runs. This intermediate storage rack unit has several rack tiers in accordance with the height of the roadway. Located in front of the intermediate storage rack unit is a rail-borne receiving platform which in turn carries a stacker loading device. Material moved up by means of the manipulating car can be put down on the receiving platform or material put down there can be picked up. The material can be inserted into the rack unit or can be removed from it with the loading device of the receiving platform. <IMAGE>

IPC: B60R1/06
Filed: 1982-02-24
Abstract: An attachment device for a mirror consists of a hinged part which has a holder with contact springs and is arranged in a hinged manner on a carrier. The carrier also has an equal number of contact springs which are arranged on a second holder. The hinged part and the holder are plug-connected to one another, for which purpose the hinged part has a guide groove, in the form of a dovetail, and the carrier has a guide piece which is correspondingly constructed in the form of a dovetail, which guide groove and guide piece are plugged together when the device is assembled, in such a manner that the springs are in this case in mutual contact. In order to remove the mirror which is attached to the device, it is necessary only to displace the hinged part, with its guide groove, along the guide piece of the carrier, the contact connection between the springs being interrupted at the same time.

Title: Roller press for compacting pulverulent or fine-crystalline materials
Inventor: WARNECKE KARL
IPC: B30B15/30
Filed: 1982-06-03
Abstract: The invention relates to a roller press for compacting pulverulent or fine-crystalline materials. The materials are delivered by a conveyor screw into the roller nip of the roller press. Immediately before the roller nip, the delivery channel of the delivery section is surrounded by a porous sleeve of sintered material, which sleeve forms the inner shell of a chamber which is under vacuum. The air released by the increasing compaction of the material being conveyed is extracted via the sleeve, so that even pulverulent or fine-crystalline material, which can otherwise hardly be processed, can be processed at a high degree of compaction.

Title: Broadcast receiver for vehicles
Inventor: SHIRATANI YUJI
IPC: H03J7/08
Filed: 1982-06-11
Abstract: The vehicle broadcast receiver (Fig. 1) with a tuner (2, 3, 4) which can be electronically tuned by means of a tuning voltage produced by a tuning voltage generator (16) and a received signal level detector (8, 9) furthermore contains a detector circuit (11, 12) to identify an absence of a specific signal component, a control unit (10) and a data memory (14) to store first data such as frequency and received signal level data of a currently received broadcast station and second data such as frequency and received signal level data of a standby station to be checked for programme identity. The control unit (10), containing, for example, a microcomputer, initiates re-tuning of the tuner from the present station to the transmission frequency of the standby station via the tuning voltage generator (16) when signal component absence (e.g. no audio signal) is identified. If a multiply repeated check of this type establishes that the standby station is recorded with a received signal level higher than that of the currently received station, the first and second data of the two stations are exchanged within the data memory (14) and the standby station evaluated in this way is continuously received with immediate effect. <IMAGE>
