Patent DE-3639153-A1 (DE)
Inventor: TROESCH W DR
IPC: C02F3/28
Filed: 1986-11-15
Abstract: With known carrier materials in bioreactors there is frequently blockage of the reactor with microorganisms or organic compounds. The new carrier material intends to make it possible for microorganisms or animal cells to be immobilised in a high concentration without blockage of the bioreactor occurring. 
<??>This object is achieved by using as carrier material beads which, on the one hand, consist of an open-pore inorganic sintered body which has pores which pass through the inside and are open to the outside and in which microorganisms and animal cells are able to be immobilised and grow and, on the other hand, have a density and a diameter such that, in a preset fluidised bed flow, the shear forces of the beads suffice to shear off the microorganisms or animal cells growing out of the interior of the beads and/or located on the surface. 
<??>The invention makes it possible to combine the advantages of the fixed bed reactor with the advantages of the fluidised bed reactor, and to avoid the disadvantages of both processes. The carrier material is not confined to the digestion of domestic and industrial effluents, it can also be employed for the biotechnological obtaining of essential dietary substances and pharmacological substances and of fermentation products.

Title: Process for producing packing material from products of the SO2/NOx simultaneous flue gas scrubber
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-12-30
Abstract: It is known to produce land filling material or below-ground mining water, resistant to leaching by water, from a flue gas desulphurisation gypsum by addition of electrostatic precipitator ash, cement and a small proportion of calcium chloride dihydrate. However, this does not succeed in the case of the abovementioned material composition if this includes products from the SO2/NOx simultaneous flue gas scrubber which predominantly comprise alkali metal sulphate salts in the scrubber solution or concentrated to 70%. It has now been found that material resistant to leaching by water can also be prepared from the products having a high alkali metal sulphate content by adding the stoichiometric amount of calcium chloride dihydrate to the water portion having the high alkali metal sulphate content, before the addition of electrostatic precipitator ash, flue gas desulphurisation gypsum and cement, in order to attain neutralisation and to prevent formation of sodium hydroxide solution.

Title: Hydraulic, pneumatic and internal combustion engines. Hydraulic elevators
Inventor: SCHMOLS KARLHEINZ
IPC: F02B75/32
Filed: 1987-03-02
Abstract: All utilisable forces were to be used, in order to raise the working fluid again, especially in those systems which can replace this fluid only with difficulty, and in order to meet the power consumption of the systems and in addition to obtain a maximum utilisable force. For this purpose, the intermediate chambers of the rising shafts are designed as pressure chambers with the associated piston rods, crankshafts, etc. The rotary or sliding elements are used as contra rotating plates. The difference in total weight between an empty and a filled rising shaft is utilised in that two co-operating rising shafts are located on a rocker or on gas pressure vessels, which are connected to one another and at the same time utilise the kinetic energy when an empty rising shaft is filled. It is also aimed to achieve a stocking of filled collecting vessels and collection of working fluids in a reservoir in the upper or lower position. Likewise a working separation into rising shafts and shafts merely for lowering the collecting vessels. In this, the rising shaft requires a shaft which is designed solely to receive and deliver fluids and also stands on the rocker/pivot.

Title: Measuring device for a physiological component dissolved in liquid
Inventor: FRANETZKI MANFRED DR
IPC: A61M5/142
Filed: 1987-04-16
Abstract: A measuring device (1) implanted in the physiological of a patient for physiological components dissolved in liquid comprises a housing (3) in which a large surface-area, semipermeable membrane (5) is inset. The membrane (5) is connected via a feed line (11) to a measuring sensor (13). A conveying device (15) sucks physiological components dissolved in liquid toward the membrane (5). After passage through the membrane (5) a filtrate is obtained on the other side thereof. The filtrate is transported to the measuring sensor (13) where it is measured. The measured values delivered by the measuring sensor (13) are either transmitted wirelessly out of the patient's body or they are fed directly to an implantable medicament metering device for control of the metering rate. The advantage of the measuring device (1) is that interfering substances are kept away from the measuring sensor (13) and constant measurement conditions are maintained. <IMAGE>

Title: Firing weapon operated by compressed gas
Inventor: ZANNER GEORG
IPC: F41B11/723
Filed: 1987-04-25
Abstract: The valve of a firing weapon which is operated by compressed gas, for example an air-pressure rifle consists of a membrane seal (diaphragm seal) which is arranged in a channel leading from the compressed-air cylinder to the barrel bore. The channel has a perforation into which the membrane seal is pressed from the outside with the aid of an operating element which can be displaced transversely with respect to the channel, and thus closes the channel. In the closed position, the operating element is held by a retaining catch which is connected to the trigger of the weapon. When the trigger is operated, the retaining catch is released, so that the tensioned membrane seal can spring back and can open the channel for the passage of air. The membrane seal according to the invention enables direct, unimpeded flow of air from the compressed-air cylinder to the barrel bore, and virtually vibration-free firing. In consequence, the firing accuracy of the weapon is improved.

Title: Device for vertically adjusting the upper deflection fitting for the belt of a safety-belt system, especially of a motor vehicle
Inventor: BAUER JOSEF-PETER
IPC: B60R22/20
Filed: 1987-10-24
Abstract: A device is proposed which is used for vertical adjustment of the upper deflection fitting for the belt of a safety-belt system. The adjustment device includes a belt which secures a person sitting in a seat which can be adjusted at least in a horizontal direction, the said belt being tensioned essentially in the shape of a triangle, a first side of which passes over the lap region of the said person and a second side of which extends from the deflection fitting to the first side via the shoulder and chest regions of the person. That section of the second belt side which extends from the deflection fitting to the shoulder of the person encloses, together with a perpendicular, a predetermined running-out angle which is automatically observed by vertical adjustment of the deflection fitting and is monitored by a drive device which is controlled by a sensor. To ensure that people of all sizes, especially people who are very large or very small in relation to the seat, can be correctly secured in all possible seat-positions, each seat position has allocated to it a specific running-off angle of the belt section leading to the shoulder of the person, which angle is modified together with the seat position in question. <IMAGE>

Title: Arrangement for determining the filter setting in colour enlargers
Inventor: HAVERKAMP GUENTER DIPL ING
IPC: G03B27/73
Filed: 1987-11-17
Abstract: In the colour analysers which are most commonly used the spectral composition of the light which is emitted by the enlarger lens and is intended for exposing the photographic paper is adjusted in such a manner that the mean value which is taken of the colours over the entire picture is "grey". In the case of colour preponderances in the picture this leads to faulty filtrations. Known arrangements which make it possible to assess and filter the picture with the aid of a video monitor are complex and expensive in terms of apparatus. The novel arrangement shall make it possible to set the filters by means of assessing the picture on the video monitor, while having at the same time a simple construction. The beam bundle leaving the enlarger lens is concentrated by means of a simple convex lens arrangement in such a manner that an image of the negative in the enlarger is produced on the target of a colour video camera by means of its own lens system. In the convex lens arrangement which has to be calculated in a known manner for the focal length of the respective enlarger lens the first lens has to be treated as an auxiliary (supplementary) lens and the second as a field lens.
Patent DE-3739922-A1 (DE)
Title: Circuit arrangement for preventing the burning-in of still images
Inventor: HEINZERLING HARTMUT DR
IPC: H04N3/20
Filed: 1987-11-25
Abstract: In screen devices with raster display, the individual lines of the raster are frequently written not closely together but a detectable space remains between the raster lines. As a result, the fluorescent material of the screen is severely stressed on the raster lines and it fatigues whilst the original efficiency of the phosphor is retained in the intermediate spaces. If the displayed image then slightly shifts on the screen later, for example by change in the external magnetic field, these different stresses become visible due to different brightnesses and, in particular, generate a disturbing moiré pattern. To prevent this, a very low-frequency signal with a period of about 60 seconds and slow signal transition is superimposed on the vertical deflection current, as a result of which the image displayed on the screen periodically shifts so slowly that it is not noticeable by the user. A circuit arrangement for generating a suitable signal is also specified. <IMAGE>

Title: Image processing method
Inventor: BERNDT ERNST-ULRICH DIPL PHYS
IPC: H04N1/38
Filed: 1988-03-17
Abstract: For processing pixel information items of only one picture segment of a picture original, it is known first to scan these pixel by pixel by means of an optoelectronic scanning device, to store the pixel information items thus obtained and to display them on a screen display device in order to establish with the aid of a pointer control device on the screen the desired picture segment, the pixel information items of which are subsequently processed further. To dispense with a screen display device with a pointer control device or other special coordinate input device for establishing the picture segment (4), optically scannable markings (2, 3) are applied to the picture original (1) for establishing the picture segment (4), detected by optically scanning the picture original (1) and distinguished from the remaining pixel information items via a threshold detector during this process. <IMAGE>
