Patent DE-3806520-A1 (DE)
Title: Heat-treatment installation with a continuous furnace
Inventor: MUNZERT KARL-HEINZ DIPL ING
IPC: F27D3/02
Filed: 1988-03-01
Abstract: In known heat-treatment installations with a continuous furnace, the rectangular transport means in the form of carriages or tables etc. are transported through the continuous furnace in their longitudinal direction; this gives rise to long, narrow continuous furnaces. These are expensive and have a great space requirement. According to the invention, the continuous furnace is constructed in such a manner that the transport means can be transported through it with their longitudinal axis (L) perpendicular to the running-through direction (D) and can outside be displaced in the longitudinal direction again. The installation is suitable in particular for drying and baking goods, in particular ceramics. <IMAGE>

Title: Apparatus for producing hollow bodies with a texturing on at least one of the outer surfaces
Inventor: IRSCH PETER
IPC: B29C48/90
Filed: 1988-05-09
Abstract: To give sheet-like hollow bodies, for example in shingle form, a surface texture which corresponds to the natural grain of a wooden board, a film which is embossed in such a way as to produce the impression of a large-area texturing is adhesively attached onto the hollow body. The novel arrangement is intended to make it possible in a simple way to produce quickly and reliably hollow bodies of which the surface has an unalterable texture. An embossing device is arranged downstream of the extruder with die head. Arranged inside the mould as a mould core is a supporting plug, which is connected to the die head by means of a holding line and is arranged opposite the embossing device. The apparatus makes it possible to give the surface of a sheet-like hollow body an unalterable texture.

IPC: B01D53/86
Filed: 1988-06-16
Abstract: In a method for the catalytic treatment of a flue gas stream, in particular for the conversion of NOx, the flue gas stream is brought into contact with ferromagnetic catalyst particles. In order to achieve an intimate contact of the flue gas with the catalyst particles without a shaped catalyst body, the ferromagnetic catalyst particles are added to the flue gas stream and entrained in this over a certain adjunct section. At the end of the adjunct section, the catalyst particles are magnetically ejected from the flue gas stream.   <IMAGE>

Patent DE-3836322-A1 (DE)
Title: Crushing rolls
Inventor: JAKOBS WILLY
IPC: B30B3/00
Filed: 1988-10-25
Abstract: In known crushing rolls, in particular roll crushers, the highly wear-resistant cylindrical casings or crushing rings, which are constructed in one piece, are fixedly connected to the roll basic bodies by shrinking-on or the like. The construction and fastening of the highly wear-resistant casing to the roll basic body in this case involves a relatively large outlay in terms of labour, time and costs. Furthermore, in particular in the case of highly wear-resistant casings shrunk onto the roll basic body, as a result of thermal stresses occurring between the roll basic body and the highly wear-resistant casing in operation, fractures of the highly wear-resistant casing can result very easily. According to the invention, however, these disadvantages are eliminated in that the highly wear-resistant casing (2) is connected to the roll basic body (1) by frictional engagement. In the event of temperature differences occurring between the basic body and the casing in operation of the crushing rolls, the casing can, on the one hand, roll on the basic body and can, on the other hand, be very easily replaced by a new casing when it is worn. <IMAGE>

IPC: G01D7/06
Filed: 1989-01-30
Abstract: The invention relates to a display/playback unit for a vehicle, which unit comprises: a reflective device with an electric unit, a support device which has a connection part which can be electrically connected to the electric unit and disconnected therefrom, the said support device detachably securing the reflective element at one point of an instrument panel of a dashboard with the reflective face of the said reflective element directed towards a driver's seat, and a display device arranged at any other point than the one on the dashboard, the display surface of which second display device is directed towards the reflective surface in order to project onto the reflective surface different operational information displayed on the display surface. Since the reflective device according to the invention is provided with an electric unit and a removable connection component, it can be easily replaced by other designs of reflective devices. Since a solar cell is provided at the rear surface of the reflective device, the electromotive force reduced by self discharging of batteries of the vehicle can be compensated.
Patent DE-3902982-A1 (DE)
Inventor: MOELDERS HORST H DR RER NAT
IPC: C12Q1/6897
Filed: 1989-02-01
Abstract: Process in which microorganisms equiped with a plasmid vector, pGL4, constructed by molecular biological techniques, can be used as biosensors for mercury compounds. A gene complex (mer-Operon) inductible by mercury ions is combined by molecular cloning with the luciferase (LUX) gene system of Vibrio Harveyi. The arrangement of the two gene units is designed so that the mer-Operon promoter, which is positively regulated by mercury compounds, also controls the transcription of the LUX genes. As a result, microorganisms transformed with plasmid pGL4 respond to increasing quantities of mercury cations in the surrounding medium with an increase in their emitted bioluminescence. The process is absolutely specific for mercury, rapid and highly sensitive: the proven limit for mercury ions is approximately 0.2 ppb, i.e., 5 times lower than the detection threshold for the most powerful established methods (atomic absorption spectrometry), which detect 1 to 5 ppb of mercury and require a considerable quantity of apparatus. A further advantage of the invention is the possibility of determining measurement values (bioluminescence signals emitted by microorganisms transformed by plasmid pGL4) without direct contact between the biosensor and the signal-amplification unit (bioluminescence apparatus). The method therefore permits simple, continuous, on-line determination of critical mercury concentrations.

Title: Germinating block for seeds
Inventor: FABRITZ GERHARD
IPC: A01G31/00
Filed: 1989-05-30
Abstract: The invention relates to a germinating block which consists of a porous, lightweight material and, after the addition of water, permits the germination of seeds and the growth of the same to form plants. In accordance with the figure shown in the drawing, the germinating block comprises a block 1 which is produced from rock wool and in which vertical bores (2) are provided. Said bores are alternately filled with granules 3, consisting of a highly swellable polymer, and a mineral fertiliser 4, between which seeds 5 are introduced. The granules 3 consist of a completely neutral polymer and are capable of absorbing more water than would correspond to their own volume. The fertiliser contains all the minerals which are necessary for plants and is made ready for plants by the water absorbed in the granules. That is to say, after the addition of water into the bores 2, the germinating and growing procedure can begin. The germinating block is suitable for long journeys in space and, by the cultivation of appropriate plants, is intended to provide natural vitamins for the astronauts. <IMAGE>
