Title: Device for grooving continuously fed flat workpieces
Inventor: RAUTENBERG HORST
IPC: B31B50/25
Filed: 1993-03-30
Abstract: A device for grooving continuously fed flat workpieces for forming folding lines comprises a grooved disc provided with a circumferential groove, in which groove there engages the circular blade of a grooving disc, which forms the grooving tools together with the grooved disc. A clamping roller running on a cylindrical section of the grooved disc prevents a drawing in of the free outer region of the workpiece in the direction towards the cooperating grooving tools. To reduce the constructional expenditure, the clamping roller comprises a cylindrical disc adjoining the grooving disc and rotating at the same rotational speed as the grooving disc.

IPC: E04D13/00
Filed: 1993-04-10
Abstract: A liquid-tight coupling for plastic webs to be interconnected in order to form a sealing wall has an inner part (1) and an outer part (2) constituted by a positive and a negative profile. The outer part is designed as a cable profile and forms an inner chamber between its branches for receiving a sealing zone, in particular a heat-sealable zone. Before both coupling parts are assembled, this inner chamber is closed by an easily severable link arranged at the ends of the branches to protect the sealing zone from dirt. This link is only opened when the inner part is threaded into the outer part. In the inner chamber of the outer part (1), which in the assembled state of the coupling parts (1, 2) is outwardly closed by seals, in particular labyrinth seals, is provided at least one heat-sealable sealing zone (15a*, 15b*) which may be activated by at least one heating element (16a, 16b) controllable from the outside and arranged in the proximity of said sealing zone.

IPC: H03M13/15
Filed: 1993-05-19
Abstract: A Reed/Solomon decoder is proposed, which has a device (6) for producing error (fault) value and error location polynomials using determined syndromes S(x) and extinction (cancellation) locations L(x) in accordance with a Euclidean algorithm. In this case, a first Galois field (GF) multiplier (18) is used to produce the error value polynomial Rs(x) = (Qs-1(x))Rs-1(x) + Rs-2(x), to the input side of which multiplier are fed a coefficient of the intermediate value polynomial Qs-1(x) = Rs-2(x)/Rs-1(x) from a first register (27) as well as an error value polynomial Rs-1(x) which can be picked off from a second register stack (61). An output signal of the GF multiplier (18) is cumulatively added in an EXOR stage (22) to the error value polynomial Rs-2(x) which is present at the output of a third register stack (58). A further GF multiplier (52) is provided for producing an error location polynomial Ts(x) = Qs-1(x))Ts-1(x) + Ts-2(x), to which multiplier are likewise connected the intermediate value polynomial Qs-1(x) as well as an error location polynomial Ts-1(x) which can be picked off at the output of a fourth register stack (61). Output signals of the GF multiplier (52) are added in an EXOR gate (56) to an error location polynomial Ts-2(x) which is present at the output of a fifth register stack (58). The coefficients of the intermediate value polynomial Qs-1(x) are produced by a sequential device (33 to 40) for the division of the output data of the third and fourth register stacks (58, 61). <IMAGE>

Filed: 1993-12-17
Abstract: The invention consists of a coder and a decoder. The encoder includes a difference picture operation, 102, 115, 103, for scaling down the motion picture stored in a frame memory, 2, by frame to obtain the difference picture between the previously transferred picture and the scaled down picture. A mode selector selects, based on the difference picture, whether the current frame is compressed according to an intra mode or an inter mode. Error picture transfer means for enlarging the compressed motion picture to the original picture, 111, 116, 112, 113, and obtaining and transferring the error between the compressed motion picture and the enlarged picture, 114, 3, 4. The decoding process being essentially the inverse of the above (see fig 2 not shown). <IMAGE>

Patent DE-4344740-A1 (DE)
Title: Split keel with jet effect for yachts
Inventor: PETERS GUENTER J DIPL ING
IPC: B63B3/38
Filed: 1993-12-24
Abstract: The split keel consists of two inward-sloping keel plates (1,2) which form a jet. The water enters it and a jet of water is formed. The jet is strengthened by water influx from the outside of the keel entering through slots under suction. When the yacht is moving, a pressure from below builds up, which is directed on to the external surface of the keep plate in a windward direction (9) to act against the heel. The lee side keel plate is more or less vertical, and the downward pressure exerted here forms a `virtual ballast' - the more so, the faster the yacht is sailing. The jet stream on its way out has a positive influence on the rudder.

Abstract: A system for engine monitoring and/or reducing engine emissions for an internal combustion engine (10). This system includes a plurality of sensors (12, 14, 15, 16, 22, 24), which register various engine operating conditions and generate corresponding output signals. At least one of these sensors is a gas sensor (22, 24), which is connected to the exhaust gas system and generates an output signal dependent on the concentration of nitrogen oxides in the exhaust gases. A central unit (24) receives the various sensor outputs and monitors, in accordance with previously programmed algorithms, a failure and/or deterioration both of the various components of the emission reduction system and of the various sensors. Furthermore, the central unit generates output signals which control the function of various engine components (30, 32), in order both to optimise the operating state of the engine and to comply with statutory regulations with reference to engine emissions. <IMAGE>
Patent DE-4403014-A1 (DE)
IPC: E04F13/08
Filed: 1994-02-01
Abstract: A process and device are disclosed for lining a static support (1) with plastic boards (2). The plastic boards (2) are linked to the static support (1) by a plurality of anchors (3) with a mounting technique that compensates during mounting for thermal expansion differences that cause the displacement of the positions of the board holes and anchors (3). In spite of the plurality of anchoring points, a uniform flank contact between the board (2) and the anchor (3) is ensured at all fastening points. Static calculations concerning the fastening points may thus be performed. Special measures are proposed in order to reduce the forced material stresses in the plastic boards (2) due to differential expansion.
