Patent DE-3425084-A1 (DE)
Title: Apparatus for drying an air stream
Inventor: PLATE JOACHIM
IPC: B01D53/26
Filed: 1984-07-07
Abstract: The invention relates to an apparatus for drying an air stream, having an air-permeable, drivable drying roll rotatably arranged in a housing, to which roll air can be fed via a fan and which contains moisture-adsorbing material and is provided with a drying zone for the air to be dried and a regeneration zone to which heated air can be fed as regenerating air. In order to make the construction and air supply simpler and to utilise a larger area of the drying roll and to make the apparatus more secure to transport, the drying roll is arranged in a flow channel which branches at the inlet side into a moist air channel connected to the drying zone and into a regenerating air channel connected to the regeneration zone. An air heating device is arranged in the regeneration air channel. The flow channel is provided on the outlet side with an evaporation channel connected to the regeneration zone, which evaporation channel is arranged in a dry air channel connected to the drying zone of the drying roll. The drying roll rotates at low speed and is driven either by a belt drive or via a central shaft. When it is driven via a central shaft, the drying roll is arranged slightly at an incline in the flow channel. <IMAGE>

Title: Process for generating ozone
Inventor: ALBRECHT ERHARD ING GRAD
IPC: C01B13/11
Filed: 1984-08-16
Abstract: The generation of ozone by silent electric discharge is more effective in many cases if the starting gas used is oxygen rather than air. In this case, the generation of oxygen in a pressure-swing adsorption plant (3) is advantageous. It is true that plants of this type only permit the generation of oxygen having a certain proportion of impurities, essentially nitrogen. Proportions of nitrogen, as a rule below 10% by volume, are desirable, however, in ozone generation because the ozone generators have their optimum operating range at such proportions of nitrogen. In plants of this type, a tank (6) containing liquid oxygen is often also installed in order to ensure the oxygen supply in case of failure of the pressure-swing adsorption plant. The heat flow into the tank gives rise to continuous evaporation of liquid oxygen. To prevent the evaporated oxygen from being lost as waste gas, it is admixed to the oxygen extracted in the pressure-switch adsorption plant, and the pressure-swing adsorption plant at the same time is operated in such a way that the gas entering the ozone generator (5) contains impurities so as to ensure optimum operation of the generator. <IMAGE>

Patent DE-3434952-A1 (DE)
Title: Circuit arrangement for monitoring an incremental measurement value pick up
Inventor: MEISTER WERNER ING GRAD
IPC: G01D5/244
Filed: 1984-09-22
Abstract: To monitor incremental measurement value pick ups which supply phase-shifted output signals for detecting direction, these output signals are supplied to several switching stages (comparators). The position of the alternating voltage amplitudes supplied to the individual switching stages, and the switch-over levels, are selected in such a manner that at least one of the switching stages is switched over at any time, but when an amplitude is too small or is missing, a switching gap is produced which triggers a fault signal.

Patent DE-3439822-A1 (DE)
Title: Process for the production of a plastics film with a grain structure, in particular a natural leather grain structure
Inventor: BOETTCHER HUGO
IPC: B29D99/00
Filed: 1984-02-20
Abstract: In a process for producing a plastics film with a grain structure, in particular a natural leather grain structure, a layer of liquid plastic is poured or spread onto a film web having the grain structure in negative form, vulcanised and then peeled off. The film web used which has the negative form of the grain structure is made of silicone rubber. This has the advantage that the film web can be produced very simply by pouring onto complicated surface contours and reproduces these contours in a precise negative form, so that the precision is repeated during the subsequent pouring or spreading procedure and, because of the elasticity of the silicone rubber, the complicated embossing structure of the silicone rubber film web is not impaired during peeling off of the vulcanised layer.

Patent DE-3519169-A1 (DE)
Title: Edge extractor hood
Inventor: LANDGRAF JOERG-DIETER
IPC: F24C15/20
Filed: 1985-05-29
Abstract: The edge extractor hood consists of a housing which is open at the bottom and is virtually divided into two chambers by an exchangeable filter element 5. The chamber lying in the flow direction downstream of the filter element 5 is connected via an air extractor nozzle 7 to a corresponding extractor fan. Arranged in the flow direction upstream of the filter element 5 is a partition 4 which preferably runs obliquely upwards and leaves one or more air gaps 2 free, in particular in the region of the side wall 8. As a result, the air speed is substantially increased, thus ensuring that vapours and the particles to be removed, in particular droplets of fat, are reliably carried along. The partition can be folded down so that the air gap 2 can be varied and the filter element can be exchanged when saturated. Provided in the region of the air gap is a fat collection groove 1 into which the fat can run due to the oblique position of the partition, said fat not being absorbed by the filter element 5 but running back downwards. Furthermore, the fat collection groove 1 serves for receiving condensing vapours. <IMAGE>
