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 u 1,i  and N/2 difference elements v 1,i . In a subsequent iteration step the N/2 sum elements u 1,i  are converted into N/4 further sum elements u 2,i  and N/4 further difference elements v 2,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.

Abstract: Beverages and beverage concentrates nutritionally supple­mented with significant levels of solubilized calcium and containing low levels of sulfate, preferably in combination with low levels of chloride, are disclosed. These beverages and concentrates also contain specified levels of edible acids selected from phosphoric acid, citric acid, malic acid, fumaric acid, adipic acid, gluconic acid, and lactic acid, as well as mixtures of these acids. The particular acid systems are selected to provide the desired flavor and sourness character for the beverages and concentrates. Inclusion of low levels of sulfate/chloride in these beverages and concentrates provides a quicker onset of sourness, prevents or reduces aftertaste effects and improves the solubility of the calcium, particularly when high levels of phosphoric acid or citric acid are used. Inclusion of sulfate/chloride also prevents or reduces the precipitation and deposition of calcium salts on equipment surfaces during the pasteurization or sterilization of calcium-containing fruit juice beverages.

Abstract: Dirty air contaminated with cotton dust or the like is alternately directed against the left-hand section of a filter screen (24), then the right-hand section by a pair of movable baffle plates of vanes (28, 30). While the dirty air impinges upon one section of the filter screen (24), backwash air is blown in the reverse direction through the opposite section of the other section to flush the impurities there collected. Upon receipt of a pressure differential generated signal that the one side is loaded, the baffle plates or vanes (28, 30) are moved to the opposite position whereby the one section of the filter screen is cleaned by the backwash air while the dirty air impinges upon the opposite side section. The interior of the filter apparatus is so constructed that the backwash air, after passing through the filter screen (24) in the reverse direction circulates back beneath the vanes (28, 30) and exits in the forward direction through the screen with the clean air.
