Title: Method and apparatus for determining the carbonate content of a partially spent limestone suspension
Inventor: GLASNER ALFRED DIPL ING
IPC: B01D53/50
Filed: 1988-03-19
Abstract: The invention relates to the regulation of a wet flue-gas desulphurisation plant in which the absorption agent used is a circulating limestone suspension which is continuously replaced. The regulation of the addition of limestone powder is carried out as a function of the carbonate content of the circulating suspension, so that there can be no breakthrough of the SO2 peaks in the emission values with oscillating SO2 content in the waste gas within a certain bandwidth. For this purpose, a constant part in the order of some millilitres per minute are continually taken from the circulating limestone suspension and conducted via a branchline (1, 2) which branches off from the feedline (4) for the sorption suspension to the SO2 absorber (5). The branchline (1, 2) is divided by means of a multi-way valve into two parts (1, 2) which are influenced by the setting of the multi-way valve in such a way that in one position the parts (1, 2) has gas flowing through and in the other position only part one has gas flowing through, while the second part is connected to a reaction vessel (6), so that the respective line content can be regarded as content of the measurement vessel which contains a constant volume of a suspension which is split into a solution or suspension and a gas buffer in the reaction vessel (6) by interaction with an acid. The amount of the gas produced is directly proportional to ... Original abstract incomplete. <IMAGE>

Title: Adjusting device for a solenoid-type spring brake
Inventor: WINKELMANN SIEGFRIED
IPC: F16D65/22
Filed: 1988-03-25
Abstract: The magnet body of this spring brake consists of individual parts (11, 12, 13) arranged in the form of a ring and held together by a common plastic jacket (14) and of a back (17) in the form of an annular disc arranged axially in front of the said individual parts. The old screws (9), which are inserted between the individual side-limb pieces (11, 12) through the plastic jacket (14), are screwed into the associated motor flange (1). According to the invention, the screws pass through a motor-side adjustment sleeve (21) whose external thread engages, within the plastic jacket (14), in the internal thread of the threaded bush (8), which is held against rotation in the plastic jacket (14) and supported axially against the back (17) of the magnet body. The plastic jacket (14) remains free of stresses which would test its strength and of threaded holes and its axial distance from the motor flange (1) is infinitely variable, a gap between the motor flange (1) and the plastic jacket (14) providing ease of access to the spanner engagement surfaces (22) of the adjusting sleeves (21) from the sides. <IMAGE>

Title: Method and device for the contactless, three-dimensional measurement of an irregular body
Inventor: RADU MICHAEL DR
IPC: A61C19/04
Filed: 1988-03-26
Abstract: The invention relates to a device and a method for the contactless, three-dimensional measurement of an irregular body (8), in particular a tooth or a row of teeth, which has a plurality of partial surfaces which can be irradiated without shadows from in each case one light source (6).

Title: Operating arrangement for hydraulic clutches, especially for marine reversing transmissions
Inventor: PETERS DIETER DIPL ING
IPC: F16D48/02
Filed: 1988-08-30
Abstract: The invention relates to a clutch for controlling the operation of hydraulically operated clutches. The aim of the invention is to develop a control for the hydraulic clutches which is favourable in terms of production technology, easy to manage and maintenance-free. The underlying object was to provide a technically simple solution which guarantees     - a delayed pressure build-up   - positive sequence control of both clutches   - clutch operation at reduced speed of rotation and - intensive lubrication of the clutch during the selecting operation.     According to the invention, this is achieved by the provision for each of the two clutches of a hydraulic control unit, a non-return valve, a double non-return valve and an adjustable throttle valve in such a way that the flow of pressurised oil of the selected clutch is first of all used for the intensive lubrication, this being gradually restricted by longitudinal displacement of two pistons with a simultaneous pressure rise in the flow of pressurised oil, this however being dependent on the opposing clutch being unpressurised and the lubricating-oil pressure and hence the speed of rotation of the transmission having fallen below the nominal value.

Title: Device for producing a smoothed DC voltage from an AC or three-phase voltage source, and method for controlling the relationship between the magnitude of the AC or three-phase voltage and the magnitude of the smoothed DC voltage
Inventor: GEKELER MANFRED W DR ING
IPC: H02M7/12
Filed: 1988-10-01
Abstract: The invention relates to a device for producing a smoothed DC voltage from an AC or three-phase voltage source, and to a method for controlling the relationship between the magnitude of the AC or three-phase voltage and the magnitude of the smoothed DC voltage. For this purpose, two series-connected capacitors are connected in parallel with the existing smoothing capacitor. A two-way electronic switch is positioned between the centre tap of the series-connected capacitors and one of the conductors of the AC or three-phase voltage source. The two-way electronic switch is operated via a control device in such a way that the smoothed DC voltage produced is, to a very good approximation, independent of fluctuations in the AC or three-phase voltage (mains voltage fluctuations) and of the magnitude of the load current drawn off. <IMAGE>

Title: Process and apparatus for breaking up melts
Inventor: KAISER HERBERT DIPL ING
IPC: B29B9/00
Filed: 1988-10-11
Abstract: In a process for breaking up melts comprising paraffins or similar materials for producing granules, the melt is deposited in the form of strips of equal width onto a cooling belt which circulates endlessly between two deflecting rollers and on which the melt is made to set. By deforming the cooling belt, the set strips thus formed are shattered as they are detached from the said belt and are consequently broken down into granules.

Title: Drilling support
Inventor: BIER MANFRED
IPC: B25H1/00
Filed: 1988-10-25
Abstract: The invention relates to a drilling support for holding and handling drilling machines during overhead drilling, having a supporting rod, an advancing device arranged in the upper region of the supporting rod and connected to a clamping device for the drilling machine, and having a lever mechanism for actuating the advancing device. The object of the invention consists in improving the use characteristics of such known drilling supports. According to the invention, this object is achieved in that the axis of rotation of the lever on the supporting rod is arranged so far down that, when the drilling support is handled by a user who is standing, the lever for producing the drilling advance can be actuated by pressing from the top downwards. As a result of this ergonomically expedient lever device, the user of the drilling support experiences the least possible strain and can achieve an enhanced performance compared with conventional drilling supports.
