Title: Articulated-arm awning
Inventor: CLAUSS ULRICH
IPC: E04F10/06
Filed: 1981-05-19
Abstract: The articulated arms of an articulated-arm awning are, at one end, connected to an opening-out rod and, at the other end, are mounted in wall bearings above which there is arranged a driven awning-canvas shaft which is mounted rotatably in stationary bearings and onto which the awning-canvas web, connected at the ends to the opening-out rod, can be wound to form an awning-canvas roll. In order to be able to draw the retracted articulated-arm awning into a downwardly open awning casing without additional drives, the wall bearings are mounted such that they can be vertically adjusted, and the awning-canvas web is guided via a deflection device connected to the wall bearings. The result of this is that, with the action of tensile force transferred from the awning-canvas shaft to the awning-canvas web and thus to the opening-out rod, the awning can be drawn in its entirety into the awning casing, whereas, when the tensile stress eases off, the wall bearings pass into the lower position for extension of the awning.

Title: Rotary feeder
Inventor: KAYSER ROLF
IPC: B65H5/24
Filed: 1981-09-03
Abstract: In rotary feeders, especially for folding machines, the intention is to simplify the conversion to different format widths and to have regard to the movement processes which take place between the sheets in the region in which the stack flow is turned on a deflector drum. The starting point is a rotary feeder which has a loading table and a removal table lying below the latter, to which the stack passes via the deflector drum. The loading table is designed as a roller table and the surface of the removal table is formed by an endless, driveable conveyor belt extending over the full width of the feeder. Laid centrally on the roller table is the upper strand of an endless belt band which is independent of the course and guidance of the transport cloth of the removal table and is driven by the tail pulley. Guided around the return section on a deflector drum are tensioned belt bands which can be relaxed by means of transversely displaceable tension rollers and are guided back independently of the course of the transport cloth of the removal table. <IMAGE>

Patent DE-3148872-A1 (DE)
Title: Fluid friction clutch with temperature control
Inventor: MARTIN HANS DIPL ING
IPC: F16D35/02
Filed: 1981-12-10
Abstract: The invention describes a fluid friction clutch with temperature control in which it is possible to attach the entire clutch to, for example, an drive shaft of an engine by means of a central bolt passing axially through the clutch, the aim being to cool the engine. A bimetal strip provided for the purpose of temperature control, lying in front of the bolt contains a central cut-out. The fact that the bolt is freely accessible from the front side of the clutch makes extremely simple assembly possible. The invention also makes it possible to construct very flat clutches and furthermore provides the advantage that it is not necessary to remove parts of the temperature control device during assembly or disassembly. This ensures that the clutch characteristic is always constant.
Patent DE-3151438-A1 (DE)
Title: Process for producing synthesis gas by partial oxidation of slag-rich feedstocks
Inventor: CZYTKO MICHAEL DR
IPC: C10J3/84
Filed: 1981-12-24
Abstract: The invention relates to a process for producing synthesis gas by partial oxidation of slag-rich feedstocks including coal with simultaneous recovery of waste heat in the form of intermediate-pressure or low-pressure steam. The synthesis gas from the reactor is passed successively through a quench vessel, a washing nozzle and a soot scrubber, all of which are operated with water. The soot/slag agglomerates are thus completely removed from the synthesis gas. No slag deposits and consequential damage resulting from these occur in the waste heat boiler. If the content of soot/slag agglomerates in the synthesis gas downstream of the washing nozzle is only moderate, the synthesis gas can be passed through a vessel for separating gas and liquid, in place of the soot scrubber.

Title: Measuring device for plantography
Inventor: PINTAR PETER DR
IPC: A61B5/103
Filed: 1982-01-07
Abstract: A measuring device for plantography shows the dynamic loading of the sole of the foot, by means of a track into which sensors are embedded. The loads on the sensors are converted to electrical pulses and converted by an electronic device into image sequences which are preferably broken down over time. As a result, not only is the size of the contact surface of the sole of the foot shown, but also the particular loading points within this contact surface are identified. In this arrangement, these loads can be measured on the track in motion, that is to say dynamically.

Filed: 1982-01-25
Abstract: The invention relates to a pressing mould for producing highly compacted, low-texture pressed parts from powdered to grainy batch compositions, essentially comprising four movable mould parts, which are identical in pairs and designed such that, when an external force acts, they slide in and over one another in such a way that the inner volume of the pressing mould is continuously reduced and the moulding material located therein is compressed from four sides, the inactive upper and lower cover plates (mirror plates) of the pressing mould preventing any escape of the moulding material in the direction perpendicular to the action of the pressing pressure.
Patent DE-3203047-A1 (DE)
Title: Servo-controlled device for regulating the underpressure in an underpressure line system, in particular for milking plants
Inventor: HAMMERSTEIN ALBERT DIPL ING
IPC: G05D16/16
Filed: 1982-01-30
Abstract: The subject-matter of the present invention is a servo-controlled control valve which keeps the underpressure required for milking (or for other purposes) contrast in very narrow limits and independently of the air requirement of the consumers. The control valve essentially consists of an underpressure chamber (1) with an adjusting spring (2); the underpressure or measurement chamber is sealed at the bottom by a diaphragm (3). A control housing (22) is also present. It contains a lower chamber in which atmospheric pressure permanently prevails (16), an auxiliary valve (9) and a control chamber (10). The latter is sealed at the bottom by a diaphragm (2). The main valve cone is fastened to it. The housing (23) seals the diaphragm (20) against the control chamber (10). The housings (8, 22 and 23) are firmly, but detachably connected to one another. The auxiliary valve opens to a greater or lesser extent depending on the underpressure prevailing in the measurement chamber (1). As a result, there is produced in the control chamber (10), which is permanently connected via the throttle bore (17) to the underpressure line system, a variable underpressure which raises the diaphragm (20) with the valve cone (18) more or less strongly, as a result of which larger or smaller amounts of air can pass via the openings (24) and the valve seat (19) into the underpressure line system. The novelty in the present invention is that the housings (8, 22 and 23) are firmly (yet detachably) connected to one another and can be inserted in a simple way as a unit into the connecting piece (21). This facilitates the replacement of the entire valve and the cleaning of the valve seat to an exceptional degree. <IMAGE>
Patent DE-3204022-A1 (DE)
Title: Filter cartridge
Inventor: WOLF JOACHIM
IPC: B01D27/02
Filed: 1982-02-05
Abstract: Such filter cartridges are used for dechlorination, degassing, etc. The active element in the filter cartridges is generally granulated activated charcoal. The known filter cartridges have too short a contact time. By means of the invention it is possible to create filter cartridges which simultaneously have a simple construction and also a degree of efficiency which is improved many times. This is achieved in that an impermeable partition wall is provided between interior wall and exterior wall, which partition wall lies at roughly half the radial distance relative to the interior wall and the exterior wall and which is sealed at one end to one of the covers in a manner proof against the medium, and additionally in that the exterior wall is porous in a first region facing one cover and is impermeable in its second region facing the other cover, and thirdly in that the interior wall is porous in its first region facing one cover and is impermeable in its second region facing the other cover.   <IMAGE>
Patent DE-3205610-A1 (DE)
Title: Optical equipment for testing parallelism and synchronisation
Inventor: HAJEN BERTHOLD
IPC: G02B17/02
Filed: 1982-02-17
Abstract: The equipment serves for the parallel offset of a collimator beam with the aid of plane mirrors and prisms. Owing to the fact that either two parallel-adjustable plane mirrors or one adjustable plane mirror and one pentaprism (which act together like a triple mirror) are combined on rigid carriers to form deflecting elements, the equipment is rendered insensitive to small displacements in all six degrees of freedom. Owing to mounting of the deflecting elements free of any bending moments, e.g. by means of a universal joint, the accuracy depends only on the adjusting stability and quality of the optical components, but not on bearing play and deformations of the supporting elements. Two deflecting elements pivotally connected to one another and through which the beam passes successively permit parallel offsetting over a variable distance. If the equipment is built up from in each case one of the described deflecting elements with a parallel offset of the same size, and one of the plane mirrors is semitransmitting, it can be folded together to form a cyclic interferometer, and this permits a particularly simple monitoring of the state of adjustment by counting the interference fringes. <IMAGE>
Patent DE-3208545-A1 (DE)
Title: Process and device for disposal of ozone from gas mixtures
Inventor: GIETMANN ARNOLD
IPC: B01D53/86
Filed: 1982-03-10
Abstract: Ozone, which is produced as a waste gas during normal technical processes or as a result of accidents, must not, on account of its toxicity, be allowed to escape into the atmosphere, but must be disposed of. Known processes for disposal of ozone are incineration, filtering using activated charcoal and catalysis on mixed metal oxides. In the catalysis on mixed metal oxides, it is usually necessary to heat the catalyst. In addition it must be ensured that the catalyst is not poisoned by water and nitrogen oxides contained in the waste gas. However, nitrogen oxides are always formed in the production of ozone from air. The catalysis of ozone on mixed metal oxides is made considerably more difficult by these secondary conditions. To simplify this process, the ozone-containing gas mixture is first passed through a container of aluminosilicate, then through the reaction vessel containing mixed metal oxides and finally through a further container of aluminosilicate. By means of a four-way valve, the flow direction is changed at intervals. On flowing through the first container of aluminosilicate, nitrogen oxides and water are absorbed. In the reaction vessel, the ozone then decomposes catalytically and liberates heat. In the second container of aluminosilicate, nitrogen oxides and water are desorbed and driven off by the now-heated gas. When the aluminosilicate in the first container is charged in this manner with nitrogen oxides and water, the direction of flow is reversed. The process manages without additional heating, avoids poisoning of the catalyst and does not consume any adsorption material. <IMAGE>

Title: Method and apparatus for removing the securing rings on bottles with screw caps
Inventor: WARNECK LOTHAR
IPC: B67B1/00
Filed: 1982-03-18
Abstract: The securing rings remaining on bottles with screw caps after the filled contents have been removed are heated by a high-frequency, in particular electromagnetic, alternating field, so that they burst open after a certain time under the action of the high-frequency field and can be removed completely from the bottle neck by simple additional means. To carry out this method, commercially available high-frequency generators can be used, in which the inductor extends partly in the form of a band in the conveying direction and on both sides of the securing rings. This method and this apparatus enable the securing ring to be burst open in a manner free of contact and hence saving the bottle material, it being possible subsequently to remove the securing ring completely from the bottle neck in an easy way by additional, known means. <IMAGE>

Title: Method for the determination of indicator running times in optically accessible blood vessels
Inventor: VILSER WALTHARD DIPL ING DR
IPC: A61B3/12
Filed: 1982-08-02
Abstract: The method for the determination of indicator running times in optically accessible blood vessels is preferably used for measurement of arteriovenous circulation times or of the mean indicator running times between two venous measurement sites in large human retinal vessels. It is the aim of the invention to reduce the measurement error on determination of the mean indicator running time difference from the measurement signals characterising the time courses of the indicator concentration at the measurement sites. For this purpose, a control signal which is in a fixed phase relationship to the measurement signal up to the possible phase shift through 180 DEG caused by the indicator passage is used by which the measurement signal is only released for further processing and recording if the associated measurement area is preferably located focally on the vessel. The invention can be applied to all optically accessible flows characterised with an indicator.
