Title: Device for depicting touchable characters
Inventor: ZAGLER WOLFGANG DIPL ING
IPC: G09F9/37
Filed: 1986-01-27
Abstract: A device for depicting touchable characters e.g. Braille characters having a horizontally arranged hole pattern board which contains holes, arranged in lines and columns, and ball channels (2...6) attached thereto for receiving vertically displaceable balls (7). The balls (7) can be fixed in their upper end positions and, in this case, project partially beyond the surface of the board and thus, with the projecting spherical surfaces, form the pattern elements of the characters to be depicted in each case. The invention consists in the fact that a circulating belt (12) is used for the final raising and fixing of the balls (7), forming the pattern elements, in their upper end position or for fixing further balls (9) which are connected resiliently to the balls (7) forming the pattern elements. Said belt (12) is guided transversely to the ball channels (2...6) in the line or column direction and is provided with at least one passage opening (13) in each case for these balls (9) per line and column. The belt (12) is synchronised in its movement with the control (14, 15) of an upwardly directed airflow (19) through the channel (5) exposed in each case by the passage opening (13), the airflow (19) being activated either for raising the balls (9, 7) into their upper end positions or for holding the balls (9, 7) located in the upper end positions. <IMAGE>

Title: Gluing mechanism for producing book blocks and multi-layer brochures with limited application of glue
Inventor: THRANDORF HANS-PETER
IPC: B42C9/00
Filed: 1986-03-27
Abstract: The invention relates to a gluing mechanism for producing book blocks and multi-layer brochures for the limited application of adhesive, especially dispersion adhesive for use in the polygraphic industry. The object of the invention is the precise restriction of the application of glue on glued book block spines at the foot and head ends, in order thus to guarantee improved quality of further processing. To this end, the book block (1), which is transported over gluing rollers (2, 3, 4) and whose spine has thus been provided with a coating of glue, is guided against processing elements by means of which a limitation of the coating of glue at the foot and head ends is achieved and the applied coating of glue is rolled smooth. The doctor blades (10, 15) used to limit the application of glue are cyclically controlled by control devices (8, 13), by virtue of whose mutual adjustment the longitudinal alteration of the restricted application (19) of glue and the recording of the alteration by different book block formats becomes possible. <IMAGE>

Title: Method for machining workpieces
Inventor: MUELLER ALFRED DR
IPC: G05B19/42
Filed: 1986-04-18
Abstract: The invention relates to a method for machining workpieces by means of a programmed multi-axial robot which guides a machining tool, preferably a laser beam along a three-dimensional workpiece contour, a marking, cutting line or the like being applied to a pattern or workpiece in order to mark the position to be machined and a three-dimensional profile NC programme being generated by scanning the marking by means of a sensor guided by the multi-axial robot, which sensor controls the axes of the robot in such a manner that the sensor always follows the markings and the coordinates of the sensor at predetermined points are input into the NC controller as programme points and then the workpieces are machined on the basis of this NC programme. To create a simple programming method for three-dimensional workpieces in which the markings, cutting lines or the like are optically detected and can be input as coordinates into the controller, a TV camera sensor (32) is used for scanning the markings (30), which sensor determines the normal of the tool and/or the tool height with respect to the workpiece surface so that the TV camera sensor (32) is oriented normally and/or at the nominal tool distance (vertically) to the workpiece surface at least at the predetermined points. <IMAGE>

Title: Device for producing monocrystalline semiconductor material
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/20
Filed: 1986-04-24
Abstract: During the production of monocrystalline semiconductor rods from polycrystalline semiconductor material, some of the semiconductor material is inductively heated by means of an RF heating coil (4) so that a melting zone (3) is produced. In addition to the alternating radio-frequency field generated by the RF heating coil (4), a constant magnetic field extending in parallel with the drawing axis is applied to the electrically conductive melting zone (3). When this constant magnetic field is applied, an eddy current damping of the convection in the melting zone (3) can be achieved. This partially homogeneous constant field is generated by a cylindrical coil (6) which surrounds the melting zone (3) and the RF heating coil (4). In order to prevent the alternating field generated by the RF heating coil (4) from generating losses in the coil (6), shielding (5) of a material with high electric conductivity is arranged between RF heating coil (4) and coil (6). <IMAGE>

Title: Process for producing composite bodies
Inventor: JENTZSCH JOACHIM PROF DR SC TE
IPC: B29C70/02
Filed: 1986-06-02
Abstract: The invention relates to the production of composite bodies from reformable moulding material and an initially formable moulding compound. The aim of the invention is a reduced outlay for the production and for joining the parts, comprising various materials, of the composite body and an improvement of the functional properties of the joining region. The object of the invention is to implement the production of the parts and their joining together with a limited number of process steps, the joining region between the materials being direct, non-releasable and gap-free. This object is achieved according to the invention by laying a reformable moulding material as semi-finished product in a mould and reshaping it by means of, as pressure transfer medium, a moulding material which is in the state of initial formability, and pressing it into the contours corresponding to the pressure direction, and fixing the moulding material, which is subject to pressure, in its geometrical development, filling the other contours of the mould. Fields of application of the invention are the production of force-transmitting and movement-transmitting elements, adaptors, bearings and insulating bodies.
Patent DE-3626842-A1 (DE)
Title: Method for determining a geometrical characteristic for curled, irregularly structured fibres
Inventor: MELCHIOR KLAUS DR RER NAT
IPC: G01N33/36
Filed: 1986-08-08
Abstract: The invention relates to a method for determining a characteristic for fibres, in particular for curled, irregularly structured fibres such as textile fibres and tobacco fibres. A specific quantity of fibres is separated on a support. A camera is used to produce two congruent pictures of the separated fibres. With the aid of a raster (grid scale), the number of the raster elements which are covered by the fibres is determined from the congruent pictures arranged one above another. The pictures are then displaced (diagonally) with respect to one another by one and/or more raster steps (x0, y0) in the (-x) and (+y) by (x/+/-y) in round figures. (For reasons of symmetry, the displacements (-x) and (-y) produce the same results as the displacements (+x), (+y), and the displacements (-x/+/-y) the same as (+x/+y)). The number of the raster elements with fibres of the two pictures, which still cover one another after the displacement, is determined and added to the number of the raster elements with fibres of the undisplaced pictures. The geometrical characteristic is produced by dividing the result by the number of the raster elements with fibres of the undisplaced pictures. The division is a normalisation. The characteristic is thereby independent of the number of fibres deposited.
Patent DE-3631377-A1 (DE)
Title: Track system of a magnetic suspension railway in an evacuated tube
Inventor: UNGER GEORG DIPL ING
IPC: B60L13/04
Filed: 1986-09-15
Abstract: The patent claim relates to the entire track system of a known magnetic suspension railway being laid in a large high-vacuum round tube (1). The high vacuum required is to be produced by a plurality of large vacuum pumps which are in operation only once during a defined time until the vacuum required has been reached. Then only the quantities of leaking air occurring have to be pumped off. At the stations, embarking and disembarking take place from the windowless cabin (2) through the cabin doors (7) and the station doors (6), which are produced as in aircraft technology, by appropriate pressure compensation, as is described in the patent application. In this way, cabin speeds of over 1000 km/h can be achieved. Located in the suction chamber (9) are nozzles for the connection of the vacuum pumps and non-return valves (10) which open correspondingly easily and can additionally quickly reduce the remaining dynamic pressure when the magnetic cabin approaches. Calculations show that, assuming current cabin drive performance, by means of this track system construction very small air densities and a lower cw value are achieved which, in turn, permit the high cabin speeds excluding any environmental influences. <IMAGE>

Inventor: PAULINI WERNER
IPC: G06F11/08
Filed: 1987-02-23
Abstract: To protect the programs contained in a system memory and to check their integrity, the programs are in each case coded in accordance with a symmetric cryptographic algorithm, by using a secret key which is stored protected against reading and during this process a test number is formed for each program and is stored in the system memory. For the integrity check, the programs are then again coded in the same manner and the test number obtained in each case during this process is compared with the test number stored during the first coding process. From the result of the comparison, a criterion can be derived for activating or blocking subsequent programs. <IMAGE>

Title: Dental cap and foil blank for producing the same
Inventor: TRUETSCH HORST
IPC: A61C5/77
Filed: 1987-04-04
Abstract: In a dental cap made of a metal foil with several foil overlaps approximately extending in the direction of the generating line for the production of a dental crown frame of a metallic-ceramic veneer crown, it is proposed that at least two foil overlaps, which are distributed roughly equally in the circumferential direction, of two lateral foil delimiting edges in each case be provided. The overlap increases toward the open front side of the dental cap at least over a part-area. Moreover, in a foil blank for the production of such a dental cap it is proposed that at least two wing-like foil tabs, which extend radially outwards, distributed roughly equally in the circumferential direction, from a central foil blank, be provided. The width of these increases outwards at least in a part-area. Said dental cap can be produced in a very simple manner from the foil blank described merely by folding-over the foil tabs, and can subsequently be varied greatly as regards the overlap dimension of the lateral foil delimiting edges. Accordingly, the dental cap can be adapted to comparatively many shapes and sizes of teeth in a simple manner. The metal foil preferably comprises a dental fusion alloy (bake-on alloy).
