Title: Auxiliary device for the production of capillary dialysers
Inventor: GROZA IGOR
IPC: B01D63/02
Filed: 1988-04-22
Abstract: In the production of capillary dialysers the ends of the capillary bundles (9) are sealed relative to the housing (10) surrounding it by means of a casting composition (16) which is brought to the correct site by spinning the housing (10) about an axis (14). In order to introduce the same amount of casting composition (16) to both ends of the housing (10) in order to avoid imbalance, the metering aid (20) is provided with two identical metering chambers (25, 26) from which the identical amounts of casting composition (16) therein can be transferred via overflows (33, 34) at the start of spinning into the housing (10) of the capillary dialyser. <IMAGE>

Title: Arc furnace having additional connectable reactance
Inventor: EHLE JOACHIM
IPC: H05B7/11
Filed: 1988-04-27
Abstract: In an arc furnace, additional connectable reactance loop arrangements are provided in the power supply of the electrodes on the secondary side of the transformer, by means of which arrangements the reactance can be increased during the melting phase so that the electrode consumption is reduced. In the refining phase following the melting phase, the additional reactances are short-circuited. The outside of the electrode support arms is provided with an electrically highly conductive layer which forms in this region the high-current conductor for the current supply to the corresponding electrode, as a result of which a power supply which has as little reactance as possible is ensured in the refining phase.

Patent DE-3821692-A1 (DE)
Title: Method for monitoring an essentially closed room
Inventor: KOLB HANS
IPC: G01S13/56
Filed: 1988-06-28
Abstract: The method is used to monitor whether people are entering a room or whether objects have been inserted into it. For this purpose, a transmitter forms a microwave field in the room, at a frequency of 60 GHz or more. A receiver having an antenna which is not located directly in the radiation area receives the reflected radiation. The radiation reflected in the quiescent state is stored as a reference value or profile. If a person enters the room, this changes the reflected radiation. This is identified and an alarm is possibly triggered. Microwaves at a frequency of 60 GHz or more do not pass through glass or glass-like materials. In contrast to the prior art, reflections from outside the room to be monitored are thus avoided.
Patent DE-3823715-A1 (DE)
Inventor: KRENKEL BERNHARD DR
IPC: D21F1/00
Filed: 1988-07-13
Abstract: The invention relates to a process and to a machine for producing a seam for making a textile web endless, which not only mechanises and automates time-consuming manual work but also accomplishes the latter in a manner which ensures troublefree automatic manufacture. According to the invention, this is achieved when the warp thread ends are strung up by machine in a magazining collar (13, 13') after removal of the fringes of the right-and left-hand fabric sides, are separated off individually according to the weaving order and alternately taken back around a central wire (16) of any desired cross-sectional area arranged in the centre of the auxiliary warp strip (15, 15') and consisting of at least one wire, and woven so that the central wire (16) is looped, corresponding to the progress of work, alternately by a warp thread end from the right-hand and left-hand fabric sides, while the respective opposite warp thread is woven back without looping the central wire, the warp thread ends being beaten up parallel to the weaving edge after introduction into the open shed corresponding to the weaving order. In place of a central wire, two parallel, not mutually joined wire coils can also be used which hold the right-hand and left-hand fabric ends in such a way that lateral sliding or shifting is prevented. <IMAGE>

Patent DE-3828413-A1 (DE)
Title: Optical system of a refractor having short focal length
Inventor: MAURI HARALD
IPC: G02B23/00
Filed: 1988-08-20
Abstract: The invention is in the field of optics and relates to shortening the focal length of refractometers (refractive telescopes, spectives) while maintaining the quality of the imagining compared to conventional spectives. The focal length was shortened by inserting a pinhole diaphragm on the optical axis at a correspondingly effective optical distance from the objective as well as a Barlow lens arranged behind the pinhole diaphragm. A precision achromat was used as objective, with a diameter of 102 mm, a pinhole diaphragm having an outer diameter of 20 mm, inner diameter of 8.5 mm. A Barlow lens having a diameter of 20 mm and a magnification factor of 3 is arranged behind the pinhole diaphragm on the optical axis and is arranged at a distance of 27 mm with respect to the pinhole diaphragm. The pinhole diaphragm itself is located at a distance of 303 mm with respect to the objective. The finder (view-finder) objective can be used in variable ways. For the model NGC 205 a finder objective having 30 mm diameter and a finder eye-piece having a focal length of 12 mm was selected. By arranging the pinhole diaphragm at a distance of 303 mm with respect to the objective and, arranged behind it, a Barlow lens at a distance of a further 27 mm, the focal length could be shortened to 495 mm for a resolution of 1.45 seconds of arc in the case of the weakest star 11. This corresponds to the focal length being shortened by more than 50% with respect to comparable refractometers, for example the refractometer Tasko model 10K. Regarding the arrangement ...

Title: Method for determining the motion vectors of a sequence of video frames
Inventor: HIENERWADEL KLAUS DIPL PHYS
IPC: G06T7/223
Filed: 1988-11-23
Abstract: In this method, the section of a video frame within a search area is determined which best corresponds to a predetermined equally large section of the next video frame following. Before the check for correspondence, the data of at least one of the sections to be compared with one another are approximated by a small number of amplitudes and the check for correspondence is carried out with these amplitudes. So that the approximation does not become too coarse and therefore the image quality does not become too poor during the reproduction of the video frames, it is provided to divide the pixels, the data of which are to be approximated, into part areas, to determine the number of amplitudes for each part area and to select the values of the amplitudes in such a manner that the mean approximation error for each part area becomes minimum.

Title: Pollutant/exhaust gas purification apparatus with water treatment cartridge for heating boilers
Inventor: ROEHNER ERNST
IPC: F23J15/02
Filed: 1989-03-03
Abstract: Air pollution by motor vehicles, aircraft and not least by oil, gas and coal heating systems has become unacceptably high. If countermeasures are not taken as soon as possible it can be predicted that difficult times lie ahead for humanity due to the pollution we have produced ourselves. In Patent Application P 3840437.0, a cavity catalyst is provided for purifying exhaust gases of heating boilers. This is currently under test so that measured values are still not available. The invention described here has a completely different exhaust gas purification method, that is to say the heating boiler exhaust gases, before entry into the stack, are purified of the toxic carbon monoxide and sulphur dioxide in a stainless steel cylinder by a steam jet, the conical wire filters which are integrated in great number in the manner of a column in the stainless steel cylinder perform the filtering out of the toxic gases and conduct these downwards dropwise at the outer rim of the filters. Only small amounts of waste water are formed by this method. A water treatment cartridge which is installed upstream of the electric steam generator prevents scale formation in the latter, an upstream fine water filter preventing blockage of the nozzle. Scale formation in the continuous flow heater built into the heating boiler is also avoided by this measure. The cleaning effect of the water freed from calcite is greatly enhanced by this apparatus.
