Patent DE-3342579-A1 (DE)
Title: Image-recording materials and image-recording process feasible therewith
Inventor: BARZYNSKI HELMUT DR
IPC: G03F1/00
Filed: 1983-11-25
Abstract: Copying film with a dimensionally stable base (T) transparent to actinic light in the wavelength region from 300 to 420 nm, and with a mask-forming layer (MS) which is sensitive to thermal radiation and contains a thermochromic system which, on irradiation with an IR laser of a wavelength greater than 1.09  mu m, irreversibly changes its absorption spectrum in the wavelength region from 300 to 420 nm in such a way that the optical density of the mask-forming layer (MS) in this wavelength region changes by at least 1.3 units. The base of the copying film can also have been applied to the light-sensitive, relief-forming layer (RS) of a light-sensitive recording material, forming a multi-layer image-recording material. By means of imagewise thermal irradiation, for example with an IR laser, a UV photomask, which is very suitable for the exposure of light-sensitive recording materials, is obtained in the mask-forming layer (MS) of the copying film.

These mixtures are particularly useful in the production of polyurethanes.
Patent DE-3401857-A1 (DE)
Title: Electric microscales
Inventor: BEHREND LOTHAR
IPC: G01G23/16
Filed: 1984-01-20
Abstract: In microscales having a beam (1) supported by a taut band, the sag of the taut band (2) varies as a function of the load. This leads to changes in sensitivity when the coil (3) of the electromagnetic compensation system thereby comes in the permanent magnet system (4) into a field domain of slightly different magnetic field strength. This change in sensitivity is now electrically corrected by providing two preferably inductive position sensors (5, 6) on the beam (1) to the left and right of the axis (2) of rotation, and by providing circuit elements which form the difference between and the mean value of the output signals of the two position sensors (5, 6). The difference signal is then fed as a measure of the angular position of the beam (1) to the control amplifier of the electromagnetic compensation system, while the mean-value signal is fed as a measure of the sag of the taut band (2) to a correction unit for the sensitivity of the scales. The correction unit contains, inter alia, a circuit for generating a non-linear characteristic in order to simulate the nonlinear spatial dependence of the magnetic field strength in the permanent magnet system (Fig. 1.). <IMAGE>

Title: Word and sentence construction trainer
Inventor: FUEHRER WILHELM
IPC: G09B1/20
Filed: 1984-05-05
Abstract: Learning devices for independent and individual work by pupils enable them to form words and sentences. The devices contain hollow cylinders or rollers (or similar hollow or solid prisms) arranged in sequence in a frame, on which lists of letters and/or phrases are printed. By rotating the cylinders, words can be assembled with the letters and sentences with the phrases. With the sentence construction trainers, a supplied colour-coded table of interrogatory words helps the pupils to call up the phrases and determine their type. The devices permit a large number of word and sentence combinations. They are a substitute for the instructional letter and reading boxes or plug-in cubes, and have the advantage of "integrity" meaning that they are complete learning aids without additional loose tiles, cubes or similar accessories, which are often mixed up or lost. The word and sentence construction trainers are thus ready for use at any time, and working with them can easily be interrupted. No clearing up, sorting or similar additional work is needed.
Patent DE-3417327-A1 (DE)
Title: Process and apparatus for keeping a predetermined pulp level in a flotation cell
Inventor: IMHOF RAINER DR
IPC: B03D1/14
Filed: 1984-05-10
Abstract: Known pulp level controls in flotation cells for froth flotation of fine-grain substances, in particular coal, are carried out with great instrumental complexity and high costs, where variations in pulp feed must have equally large variations in pulp withdrawal or froth withdrawal as a consequence in order to prevent overflow of the pulp into the froth outlet. According to the invention, maintaining a predetermined pulp level in a flotation cell is simplified and improved in terms of engineering by withdrawing the floated pulp, depending on the pulp feed rate into the flotation cell, in part beneath the foam discharge and in part at the bottom out of the flotation cell by separate outlet pipes for the floated pulp.

Patent DE-3419967-A1 (DE)
Inventor: BRENNER HEINZ ING GRAD
IPC: F16C33/22
Filed: 1984-05-29
Abstract: The invention provides an elastic articulated coupling which comprises a relatively rigid inner member having a longitudinal axis, a relatively rigid outer member having a generally cylindrical interior of a predetermined first diameter surrounding said inner member with substantial clearance, and an elastomeric body located in the clearance between the inner and outer members. The elastomeric body is connected firmly to the inner member. Additionally, a sleeve comprising wear-resistant elastic material is firmly connected to the elastomeric body and disposed between the elastomeric body and the outer member. The elastomeric body and the sleeve together have a predetermined second diameter which is greater than the predetermined first diameter defined by the interior of the generally cylindrical outer member. As a result, the sleeve is connected in a non-positive manner with the interior surface of the outer member merely by radial pre-stressing and by axial bracing.

Title: Vehicle for transporting garages
Inventor: DEURINGER MICHAEL
IPC: E04G21/16
Filed: 1984-07-11
Abstract: A vehicle with a body for loading and unloading and transporting prefabricated parts of buildings, in particular prefabricated reinforced concrete garages, has, on a frame which can be lifted out with supports, a boom which can be moved in with a rearward arm through an end-side opening of the building and connected to the building. The arm of the boom is of multi-component construction and is pivoted up and down about an essentially horizontal axle by means of at least one working cylinder, the said axle being mounted in a carriage which is arranged so as to be displaceable in a guide frame arranged on the vehicle. For the purpose of manufacturing such a vehicle in an economical fashion, it is necessary to reduce the weight of the vehicle as far as possible, in which case the vehicle must at the same time be designed to set down the garages even on inclined terrain. For this purpose, the carriage (3) has a front counterbearing (4) and a rear counterbearing (5) which are rigidly connected to one another and guided in the guide frame (2). The horizontal pivot axle (7) of the boom (12) is arranged at a distance from the auxiliary frame (2). The boom (12) is attached to a rocker (8) which can be swivelled about the horizontal pivot axle (7). The working cylinder (9) engages on the one hand on the vehicle body and on the other hand on the rocker connected to the boom (12), the boom (12) being displaceable in the rocker (8) by means of a displacement cylinder (13). <IMAGE>

Title: Air film slide for horizontal transport
Inventor: HAENEL EDGAR DIPL ING
IPC: B65G7/06
Filed: 1984-11-09
Abstract: The invention relates to an air film slide for the horizontal transport of loads under rugged operating conditions and where wear is greater. The aim and object of the invention is to extend the area of technical application to building site conditions, accommodating a higher load and increased wear. The structural members must be easily replaceable and their manufacturing costs must be kept relatively low. Vibrations are to be eliminated in partial load ranges as well. Resistance to deformation due to excessive friction is to be improved. According to the invention, a statically reinforced platform spans an air cushion device which is supported against the platform and against the sliding surface, under the platform. A tubular nozzle mounted at right angles on the underside of the platform guides the gaseous pressure medium out of the platform into the air cushion space. A throttle plate on the lower end of the tubular nozzle retards the unimpeded outflow. The resulting accumulation causes the pressure medium to overflow through bores into a diaphragm space, which consists of discoid diaphragms which are directed towards one another in a mirror-inverted fashion, are drawn tightly over the tubular nozzle and are clamped at the edges in a rim in an pressure-tight manner. Once the diaphragm space has been filled, an air buffer is formed in the air cushion space by further increasing the pressure of the medium. An air gap is formed between the lower diaphragm and the sliding surface by radial outflow of the pressure medium, with the effect ... Original abstract incomplete.

Title: Cable bulkhead
Inventor: KRAUSE RUDOLF DR ING
IPC: H02G3/22
Filed: 1985-02-12
Abstract: The invention relates to a cable bulkhead which, in the region of a wall through-opening, seals the cable which is passed through there with respect to the opening such that fire is prevented from passing through the opening from one room into the other. The outer layers, which face the rooms, of the cable bulkhead according to the invention consist of a coating material which leads to a good mechanical closure of the cable bulkhead to the outsides. This results in the cable bulkhead according to the invention being able to withstand even relatively long attacks by extinguishing water in an extremely effective manner, despite the use of intrinsically light materials, which was not possible in the case of previous seals using mineral wool.

Title: Process for the simultaneous removal of SOx and NOx from exhaust gases and apparatus for carrying it out
IPC: B01D53/60
Filed: 1985-03-21
Abstract: A process for the simultaneous removal of SOx and NOx, in particular SO2 and NO, from exhaust gases of sulphur- and nitrogen-containing fuels is described. In this case, the exhaust gas is conducted into the lower part of a scrubber (7) in which, during its ascent to the gas outlet (8), it experiences multiple horizontal deflection. At the same time it is subjected to the action of an acid, which is sprayed via spray nozzles (32, 32', 32'') and oxidises the gases to be removed. The spraying of the oxidising acid is carried out in counter-current, cross-flow and co-current to the exhaust gas flow. The exhaust gas is conducted through a plurality of stages (27, 27', 27'') arranged successively in the gas flow direction, the acid being circulated in its own circulation in each stage. For this purpose a separate acid sump (31, 31', 31'') is provided in each stage. From the sump (24) of the scrubber, excess used acid is conducted away which is reprocessed and sprayed in again into the upper part of the scrubber via spray nozzles (30) as fresh acid. <IMAGE>
