Patent NL-8700843-A (NL)
IPC: H04N7/30
Filed: 1987-04-10
Abstract: In a television transmission system for digital picture signals each picture is split up into sub-pictures of NxN pixels for the purpose of reducing the bit rate. Each sub-picture is subjected to a two-dimensional discrete cosine transform (DCT) for determining basic picture weighting factors (coefficients) which are converted by means of adaptive coding into code words of variable length. This two-dimensional DCT is realised by multiplying the pixels of each row of the sub-picture by the NxN DCT matrix (one-dimensional transform). Consequently, an NxN array of product elements is obtained. The transposed version thereof is once more multiplied by the NxN DCT matrix. Such a one-dimensional transform comprises three main steps. In a first main step the pixels of a row are converted in a first iteration step into N/2 sum elements u1,i and N/2 difference elements v1,i. In a subsequent iteration step the N/2 sum elements u1,i are converted into N/4 further sum elements u2,i and N/4 further difference elements v2,i. This process is repeated until only two sum elements are left. The difference elements obtained in each step are used to determine a plurality of auxiliary sum elements in still further iteration steps. The remaining two sum elements, the difference elements and the auxiliary sum elements are each multiplied in the second main step by an associated linear combination of elements of the DCT matrix. Of the sub-products thus obtained selected one's of those products are added together or are subtracted from each other in the third main step so that the desired product elements are obtained.

IPC: H01L41/08
Filed: 1981-12-22
Abstract: An electrically actuated positioning element system utilizes a positioning element formed of piezo-electrical bodies each formed of a plurality of lamellae having electrodes. The lamellae have a length substantially greater than their thickness and upon application of an electrical voltage with a field direction which promotes a polarization of the material of the lamellae, the body is shortened. The two bodies are connected to one another at one end by a cross arm and at the other end the one body end is active and free to move relative to the other body end such that a resultant relative motion occurring between the two body ends may be utilized. Preferably a connection is provided for absorbing a lateral thrust of the bodies. The two piezo-electrical bodies are each electrically connected to one another for reverse-phase operation such that one contracts while the other is in a lengthened condition and vice versa.

Abstract: Three paperboard webs are glued to one another with as little expenditure of energy as possible. After leaving the gluing apparatus, the finished sheets cut to size are ready for shipment. The middle paperboard web is passed through between two steel rolls which apply glue homogeneously to both sides of the web. High linear pressure is produced in the region of the generatrices of the steel rolls respectively touching the web. Such pressure is necessary in order that a highly viscous polymeric synthetic or natural adhesive, preferably with a solids content of more than 50%, can be used. No special drying facilities are needed, and the water-soluble glue allows recycling without problems.
