Title: Contact apparatus for the electronically controlled synthesis of coloured and white light for different illuminating purposes
Inventor: ROEBE-OLTMANNS HANSGEORG
IPC: F21V9/40
Filed: 1987-03-05
Abstract: The apparatus makes possible a play of colours with the colours of the visible (light, optical) spectrum and with "white". Changing from one colour to another colour can be performed continuously by means of an electronic control, in any sequence, at any speed, and with freely selectable intensity. As a result of its compact, light, and low-reaction construction, this apparatus can be used as basic element for different illuminating bodies. With the aid of the primary colours RED, GREEN, and BLUE, three light sources which can be dimmed independently of each other produce this function in a light source arrangement in accordance with subclaim 2 or 3. The lights of the light sources (2, 12, 18) is focused by the reflectors (1, 6, 19) and guided through the heat-absorbing filters (3, 7, 17). The design according to subclaim 3 has a light source arrangement having a total of only five colour filter items (see also Fig. 1). The colour filters 16 (RED, see also Fig. 2), 8 (GREEN, see also Fig. 3) and 4 (BLUE, see also Fig. 4) assign the light sources their primary colours (15 = RED, 13 = GREEN, 5 = BLUE). Two colour-splitting mirros 9 (reflecting RED, see also Fig. 5) and 10 (reflecting BLUE, see also Fig. 6) are perpendicular with respect to each other, the three partial beams meet there in each case at an angle of 45@. The design according to subclaim 2 has a light source arrangement having a total of only two colour-splitting mirror items. In this case, the colour filters 16, 8 and 4 can be saved (compare Fig. 1).

Patent DE-3716568-A1 (DE)
Title: Process and apparatus for measuring existing connections on a sewer and fitting new connections at in each case the same location on an inner pipe drawn into the sewer
Inventor: RAUSCH WOLFGANG
IPC: E03F3/06
Filed: 1987-05-18
Abstract: In the event where their use value has been reduced, e.g. by cracks or lime deposits, sewers in which it is not possible to walk have, up until now, had to be excavated from above in order to repair them. In order to avoid this expensive process, new pipes are to be drawn into the old sewers in accordance with a more recent process. The production of service connections in a new pipe cannot be carried out neatly by means of known robot vehicles because the position and angle of the relative service connection in the new pipe can no longer be established. The novel process is to permit accurate production of service connections and other line connections in the new pipe. A vehicle (1) moves up to the location of the respective connection in the sewer (15) which is to be repaired, and stores the coordinates of the connection. After the new pipe has been drawn in, the vehicle (1) automatically moves up to the connection, corresponding to the stored data, and produces the new connection. The vehicle (1) comprises, inter alia, a milling cutter, which can move along a circular or elliptical path, and a platform which is pivotably mounted on the vehicle. The process and the apparatus permit accurate production of line connections in the newly drawn-in pipe without having to excavate the sewer, in which it is not possible to walk, from above. <IMAGE>

Title: Workpiece having a layer of ceramic material and process for producing such a workpiece
Inventor: WUESTEFELD CLAUS DIPL CHEM
IPC: C23C26/00
Filed: 1987-07-08
Abstract: Ceramic layers are suitable for protecting the surface of metallic workpieces and thereby for improving the heat resistance and corrosion resistance of metallic workpieces. However, the high resistance of the ceramic materials is not fully utilised, since the layers on metal surfaces produced hitherto do not adhere sufficiently strongly and/or are porous, so that they do not ensure perfect protection. According to the invention, use is made of layers of the nitride of a transition metal, which layers adhere very well to metal surfaces and, in addition, are impermeable, so that they ensure the desired complete protection. These layers can be produced by exposing the nitride fluoride of a transition metal to a stream of ammonia at a temperature in the range from 600 to 800@C, so that the metal nitride is produced in the form of colloidal suspended particles in a gas stream and deposits on the surface to be coated of the workpiece in the form of an amorphous, impermeable and strongly adhering layer. An important field of application is the coating of the surfaces of metallic engine parts, for example of piston crowns and turbine blades.

Patent DE-3727874-A1 (DE)
Inventor: HARTNACK WOLFGANG DIPL ING
IPC: H04N19/60
Filed: 1987-08-21
Abstract: A method and apparatus for the improvement of the resolution of digital signals. In digital TV signals which are transformed into a selected frequency range, irregularities in the pattern of the reproduced video signals occur because of rounding off errors, when the number of places is reduced during calculation of the coefficients. This is remedied by increasing the coefficients of the transformed signal values following at least one first coefficient, for example a uniform component, and reducing them again before inverse transformation. This invention can be employed in digital systems using block processing in which, because of a limited number of bits, a rounding off of the transmitted spectral coefficients is performed in the calculation.

Patent DE-3800977-A1 (DE)
Title: Digital signal transmission system with line substitution operation
Inventor: SCHNEIDER WOLFGANG DIPL ING
IPC: H04L1/22
Filed: 1988-01-15
Abstract: The invention relates to a digital signal transmission system with line substitution operation in electrical telecommunications. A device ES at the receiving end is connected to a device SS at the transmitting end via a first transmission path Ü1 and a second transmission path Ü2. The data signal supplied by the data source DQ is divided into data blocks in each transmitter S1 and S2. At least one check bit is attached to each data block. The digital signal supplemented in this way is forwarded to the associated receiver E1 or E2. Each receiver contains an error-checking device which transmits an error signal FS1 or FS2 if a bit error has occurred in the associated data block. The controller St controls the changeover switch U in such a way that it switches over to the other transmission path when an error signal occurs. To ensure that, following detection of a bit-errored data block, the changeover to the other transmission path occurs before the errored bit reaches the data sink DS, the delay circuits Vz1 and Vz2 are inserted between the receivers E1 and E2 and the changeover switch U. All the corresponding bits are thus stored in the delay circuits at the time of a changeover and the errored bit is not forwarded to the data sink (Figure 2). <IMAGE>

Title: Method for counting events following one another at short time intervals by means of electronic counting devices and corresponding counting devices
Inventor: ECKENBERGER EBERHARD
IPC: G06F7/505
Filed: 1988-03-01
Abstract: In this counting method, the counting is carried out in a number of counting cascades. So that a carry, occurring during a counting process in one of the counting cascades, for the next counting cascade following in each case does not need to be forwarded through possibly a number of counting cascades, this carry is initially temporarily stored and is only taken into consideration during the next counting process following. This restricts the counting cycle to the processing time of one counting cascade. At the end of a sequence of counting processes, the counting result is determined by taking into consideration any carries which are still temporarily stored. <IMAGE>
