Title: Sifter for classifying bulk material
Inventor: KRANEPOHL DIETRICH DIPL ING
IPC: B07B7/083
Filed: 1983-03-24
Abstract: The invention relates to a sifter which separates granular bulk material into coarse-grade and fine-grade material. It is used in particular in producing raw meal for cement production using the dry method. The objective is to develop a sifter which intensively prepares the material to be sifted for classification in order to increase its effectiveness. The object of the invention consists in distributing, by virtue of the design of the material charger, the material to be sifted, which is fed in mechanically from above, uniformly over the entire circumference of the sifting zone. The object is achieved in that a very flat, ventilated charging ring container (3) is arranged above the guide blade system (5) located in the sifting space. Said container consists essentially of the loosening element (12 and 12'), the container floor (11) made of porous material and the container wall (14) with a predetermined height which is required for forming a fluidized bed. <IMAGE>

Title: Combined compact lightweight cooking set
Inventor: SCHMID DIETER FRIEDRICH
IPC: A47J33/00
Filed: 1983-06-10
Abstract: To reduce the problems of packing cooking utensils for the backpacker who requires that the carried articles be of light weight and compact, burner, cooking housing, windbreak, saucepans, frying pan, condiment containers and fuel storage containers are combined in a single cuboid pack such that these articles take up only a small amount of space in the backpacker's rucksack and are easy to find, since the cooking housing and windbreak consist of one part whose base is square with rounded corners, whereas the saucepans are round and, in the packed state, the space in the corners, between the saucepans and the cooking housing, is filled with suitably shaped condiment containers. A cuboid spirit bottle exactly fitting the dimensions of the cooking housing is put in a cuboid cloth bag together with the cooking housing, which is filled with saucepans, frying pan, condiment containers, burner and handle, resulting in a cuboid package adapted to the usual rucksack dimensions.
Patent DE-3322713-A1 (DE)
Title: Method and device for continuous measurement of the rolling angle of a movable machine part
Inventor: SCHUESSLER HANS-H DR ING
IPC: G01B11/26
Filed: 1983-06-24
Abstract: The invention relates to a method and a device for continuous measurement of the rolling angle of movable machine parts which are moved along a preferably rectilinear line of movement. To be specific, a polarimetric angular measurement is provided for the purpose of determining rolling angle, in which polarised light with a defined direction of polarisation is transmitted in the direction towards the machine part. Arranged on the movable machine part is the analyzer, which co-executes the rolling movements of the machine part. Arranged behind the analyzer is either a light detector or a reflector which retroreflects the analyzed light onto the light source; in the latter case, the light detector is actuated via an inclined semi-reflecting mirror which can form a single unit together with the light source. The direction of polarisation of the transmitted light beam can be varied by a Faraday modulator in order to compensate the rolling angle which occurs. For the rest, the direction of polarisation can be oscillated with high frequency about a central position in order to increase the measurement accuracy, the output signal being evaluated at the light detector with regard to its harmonic components.

Title: Anti-theft protective tube for air pumps
Inventor: KRZYSZTOF PUZYNA DIPL ING
IPC: B62J11/02
Filed: 1983-07-22
Abstract: This invention is a modernisation of the earlier invention patent application of 12.04.1983; file number: P 3313018.3. In order to be able to manufacture the safety tube more cheaply, the function of the locking element for preventing the sub-tubes from being compressed was assumed by special tubular sections in the sub-tubes. This permitted the special lock to be dispensed with. The simultaneous centring by means of these tube sections permitted the centring rings to be dispensed with. The anti-theft protective tube can be secured with an existing bicycle lock or a padlock. <IMAGE>

Patent DE-3331619-A1 (DE)
Title: Heat exchanger and method for producing it
IPC: F28F1/12
Filed: 1983-09-01
Abstract: The heat exchanger consists of two honeycomb plates (20, 22) which are fastened to one another and between which a prefabricated system (24) of pipes is embedded, with a deformation of the honeycomb plates. Using the honeycomb plates (20, 22) instead of otherwise conventional heat-exchanging gills considerably simplifies and reduces the cost of the production of the heat exchanger, and the heat exchanger has a substantially larger effective surface than known gilled heat exchangers. As a prefabricated part, the heat exchanger can, in addition, be deformed in order to adapt it to arbitrarily shaped cavities in which it can then easily be accommodated, such as, for example, in wall cavities of buses as part of an air conditioning system. <IMAGE>
Patent DE-3339898-A1 (DE)
Title: Apparatus for the separation of liquid mixtures
Inventor: VOLLRATH HANS-PETER DIPL ING
IPC: B01D3/14
Filed: 1983-11-04
Abstract: An apparatus is described for the separation of liquid mixtures, for example of sea water into fresh water and more highly concentrated salt solution, with the aid of semi-permeable microporous films. In this case, a heat-insulating, but transparent, coating is arranged above the radiation-absorbing liquid-and water vapour-tight top of the cavity in which the liquid mixture to be separated is located. The vapour leaves the liquid through the semi-permeable microporous film located at the bottom of this cavity, passes through an open-pored heat insulating layer and condenses in the space beneath the open-pored heat-insulating coating. This space is cooled by a double bottom situated underneath, through which flows a likewise liquid mixture. A further heat-insulating layer seals the apparatus at the bottom.

Title: Cell for receiving substances in spectrophotometry
Inventor: SCHUMACHER ERNST
IPC: G01N21/03
Filed: 1983-11-09
Abstract: A cell for receiving substances in spectrophotometry is characterised in that a plurality of entry points for the focused measuring light is provided at the light entry side of the cell and in that, accordingly, a plurality of light exit points are provided at the light exit side of the cell. The proviso is that the light paths through the substance to be measured between the light entry points and the light exit points assigned to the latter are of different lengths. In particular, at least one of the light paths is longer than the direct distance between light entry side and light exit side and at least one further light path is shorter than the direct distance between light entry side and light exit side. The lengthening of the light path is achieved by repeatedly passing the measuring light beam back and forth through the substance to be measured between light entry side and light exit side using optical light deflection means. To shorten the light path, optical guide elements made of optical glass are inserted which guide the measuring light beam in a scatter-free manner and at the same time reduce the space left between light entry side and light exit side for the substance to be measured.

The lifting stage is provided with at least one platform (12) for receiving passengers and for them to get into and out of the boats, this platform participating in the travel movement of the lifting stage. In this way, it is possible for changing of passengers to take place during the lifting operation so that the continuous circulation of the boats does not have to be stopped for changing passengers. <IMAGE>
Patent DE-3341001-A1 (DE)
Title: Nanoparticles composed of biodegradable synthetic material, process for the production thereof and their use
Inventor: KRAUSE HANS-JUERGEN
IPC: A61K9/51
Filed: 1983-11-12
Abstract: The described processes for the production of nanoparticles composed of biodegradable synthetic material, which are essentially based on an interface polymerisation in a suitable emulsion system or on a pseudolatex preparation, make it possible to incorporate both water-soluble and sparingly water-soluble medicinal substances. In addition, a greater loading of the carriers with medicinal substance is achieved. Since the incorporated medicinal substance dissolves more slowly from the nanoparticles than does free medicinal substance of comparable crystal size and, moreover, the materials used are physiologically acceptable and biodegradable, it is possible by use of these carriers to achieve both an alteration in the distribution behaviour and a more effective local administration of the relevant medicinal substance in the live body.
Patent DE-3347864-A1 (DE)
Title: Device for stacking flat workpieces
Inventor: BRINKMEIER FRIEDHELM
IPC: B31B19/98
Filed: 1983-06-28
Abstract: A device for stacking flat workpieces, preferably glued paper bags, consisting of a stacking cylinder which is provided with suction nozzles, sucks up the workpieces by their front ends and, once it has carried them over part of its circumference, deposits them, approximately vertically upright, onto a stacking table placed adjoining the stacking cylinder. In order to separate any of the articles conveyed on the stacking cylinder in an imbricated fashion which may have become stuck together before they are stacked, the distance between the suction nozzles (15) on the stacking cylinder in the circumferential direction corresponds to the lengths of the uncovered front ends of the workpieces. As a result of this, the individual workpieces are displaced in relation to one another through the length of the overlap, causing workpieces which have become stuck together to separate (Figure 2). <IMAGE>

Title: Valve for the connection of two water consumers
Inventor: EGLI WERNER
IPC: F16K31/46
Filed: 1984-04-30
Abstract: The appliance-connecting valve has a first outlet (3) to a mixer unit and a second outlet (4) to a dishwasher or a washing machine. For both outlets, a common shut-off valve (6) is present. The spindle (5) on this shut-off valve (6) exhibits, at its end, a valve seal (7) and has, in addition, a collar (8) with a conical part (10) and a cylindrical part (9). Together with a cylindrical bore (11), the flow to the first outlet (3) can be prevented or changed. In this arrangement, the volume flow to the second outlet (4) remains opened. Two water courses can thus be interrupted together. For the second water course, a diaphragm valve (14) is present which can be actuated by means of a Bowden cable (27), for example from the water basin (43). This results in a simple construction with greatly simplified operation if the second outlet (4) is intended to be non-pressurised when not in use. <IMAGE>

Title: Matrix printer with a printing head arranged on a movable carrier
Inventor: JOHANNSEN FRED DIPL ING
IPC: B41J15/04
Filed: 1984-12-19
Abstract: The requirement for a high print quality which comes close to that of typewriter print is constantly increasing with matrix printers. For this purpose, mosaic printing heads with printing elements arranged in two rows of columns are known, the printing elements of one row being arranged offset with respect to those of the other row. The printing elements in the two rows of columns are actuated in delayed fashion. In order, in this process, to produce for example a straight vertical line, stepping motors are required in which exactly identical stepping widths can be achieved. The invention is based on the object of providing a mosaic printer with which a typewriter-like print quality with straight lines and high-quality coloured graphics can be produced with a machine which is of simple and cheap design. This object is achieved in that the recording carrier (1) and the printing head (2) with the printing elements are arranged so as to be capable of being moved in relation to one another by a stepping motor (8; 11), and in that a further row of printing elements can be moved into the printing position of a first row of printing elements by n-steps of the n-coil stepping motor (8; 11) in such a way that the matrix dots produced by the further row of printing elements can be placed in a position in which they are congruent with or in a position in which they are staggered between the matrix dots of the first row of printing elements on the recording carrier (1). Using simple means, it is therefore possible to ... straight vertical and/or horizontal lines with a high resolution and ... Original abstract incomplete <IMAGE>

Patent DE-3502584-A1 (DE)
Title: Electronic apparatus
Inventor: LAYH HANS-DIETER
IPC: H05K7/20
Filed: 1985-01-26
Abstract: The housing of the apparatus is preferably formed by a metal hollow-profile part (1) which can be hermetically sealed at the ends by means of suitable end plates. The circuit elements (4) are arranged in the normal manner on carrier boards (5). To the extent that the circuit elements are heat generators (9), such as power transistors and the like, said elements are arranged on a metal plate (7), connected thermally thereto but electrically in an insulated manner, so that the heat which is produced is immediately distributed in the metal plate. Since said metal plate rests over a large area on a wall of the metal hollow-profile part (1), which wall is preferably provided with cooling ribs (2), even relatively large quantities of heat can quickly be dissipated to the exterior. The carrier boards (5) are retained within the metal profile part (1) by means of the said metal plate (7) and a strip part (10) which can be pushed into a slot (3) in the metal hollow-profile part (1) and, as a rule, carries externally accessible plug contacts, operating switches or the like and/or a connecting cable. <IMAGE>
