Title: Picture coding for, e.g. telefax and colour television
Inventor: DIRR JOSEF DIPL ING
IPC: H03M11/00
Filed: 1990-08-07
Abstract: A picture cooling system in which the digitally sensed run length for black and white or the line command (MRC) and a deviation therefrom are coded by digit. Only the individual digits that make up the numbers are coded. If necessary, several lines can be code multiplex condensed. In narrow band transmission the phase jump or phase difference and/or the amplitude difference is changed.  In television, code multiplexing condensation of all signals allows only one carrier to be used.

Patent DE-4130629-A1 (DE)
Inventor: SIEBENMORGEN GEORG
IPC: F01N3/021
Filed: 1991-09-14
Abstract: 2.1 Known filters for separating out solids from the exhaust gases of an auto-igniting internal combustion engine, where the filter can be regenerated by burning off the deposited solids and the burning-off process can be initiated by electrical heating of the filter, have the disadvantage that at least under certain operating conditions, only incomplete burning-off of solids is achieved. This is due to the fact that the solids deposit on the filter upstream of the electrical heating in the flow direction and these layers deposited upstream in particular in the case of exhaust gas flowing through the filter during the regeneration process are insufficiently heated for initiating the burning-off process. 2.2 According to the invention, the filter is heterogeneously constructed, divided into a coarse-pore layer 1 and a fine-pore layer 2, the exhaust gas initially flowing through the coarse-pore layer 1 before the solids are separated out from the exhaust gas stream by the fine-pore layer 2. At the same time, the coarse-pore layer 1 is designed to be electrically conducting, so that during a regeneration process, complete burning-off of solids is ensured. <IMAGE>

Title: Automatically cutting foam block to size - using machine which feeds block to turntable cuts two opposite sides to size, turns block through right angle, cuts again and removes prod.
Inventor: KOTONSKI ALFRED DIPL ING
IPC: B26D1/00
Filed: 1991-10-11
Abstract: Process automatically trims/cuts a block of foam in readiness for further operations and cuts outlines in partic.; a cross-cutter cuts out by a copying process from the block which is mounted on a table. The block is first cut accurately along two opposite sides, the offcuts are automatically removed from the ends of the table, the block is turned through 90 degrees, the other two sides are then cut and their offcuts again removed. The table is moved along tracks. The cutter cuts along the dotted line and has a drive and vertically moving frame. The block is fed in from belts on to the turntable and up to the position by the cutter, where it is turned through 90 degrees so that its two sides are parallel to the cutter. Two sides are then cut and the offcuts fall on to the table. The table is moved as required and the rollers are driven so that the cut block is passed over to the belt and removed by rollers. ADVANTAGE - The procedure produces accurate cuts, preventing any offcuts from interfering in the cutting operations

Title: Cross-flow rotor structure - has blade-ring frame fully integrated in lattice-work structure
IPC: F03D3/00
Filed: 1991-08-14
Abstract: The supporting structure (1) of a cross-flow rotor absorbs bending and torsion loads. The blade ring frame is fully integrated in the lattice-work structure, the tie-rods forming continuous cross-flow blades. Adjacent blades of the module form distance-pieces in place of tubes. To avoid shear loads on the tie rods, the discs of two modules which are in contact can be prevented from twisting, the structure cross-struts being fixed to them adjacent to the tie rods. On large rotors, the intermediate discs can be replaced by cross-struts and the blades can be separately produced, being adjustably mounted on the structure. USE/ADVANTAGE - Supporting structure is for cross-flow rotor.
