Abstract: An arrangement for the sealing of a shaft (2) which passes through a plate (1) which separates the "wet" and the "dry" zone of a packing machine from each other. In packing machines great demands are made on the tightness and durability of such shaft bushings, especially against strong washing agents, and the sealing assembly in accordance with the invention, therefore, has a flexible connection with the plate (1) and two O-rings (9,10), which are partly enclosed by the two halves of the sealing assembly and thereby are protected during washing as well as during operation. This design also produces a good sealing effect when during operation the shaft moves a little in radial direction.

Abstract: The invention concerns a method and apparatus for measuring web tension. The tension of a moving web is measured by locating close to the web (14) a gauging bar (1), which has its outer surface curved in the machine direction of the web (14) and carries pressure measurement sensors (2) in holes (3) formed into the bar. An air-cushion is formed between the moving web (14) and the curved surface, wherein the pressure is proportional to the tension of the web (14). The tension of the web (14) is measured in an indirect way by gauging the air-cushion pressure. The apparatus capable of implementing the method has an apparatus (7) required for the generation of a reference pressure, and the pressure measurement apparatus is used for measuring the pressure difference between said reference pressure and the air-cushion pressure.

Abstract: The current frame of the picture is compared (2) block-by-block with the previous frame to identify changed picture elements (pixels). The resulting matrix is matched ('vector quantised') (4) to one of a set of standard matrices ('VQ shapes'). Only those pixels flagged by the selected VQ shape are transmitted plus a "VQ shape code". This technique is modified in that the current frame is also compared (30) with a "background" frame stored (31) at the transmitter and at the receiver. Where, for any block, all the pixels flagged by the VQ shape are indicated by the second comparison as being the same as the background, the pixels are not sent - instead a shape code plus a "copy background" instruction is transmitted.

Abstract: The application relates to a process for synthesising carbonic allyl esters from polyhydric alcohols, which are reacted with diallyl carbonate in the presence of a basic catalyst, which can be chosen from sodium hydroxide, sodium carbonate, sodium alcoholate, organic bases or basic ion exchange resins.The final products obtained differ according to the ratio of the components of the starting mixture. Thus, in the case of diols with a diallyl carbonate/diol ratio greater than or equal to 10, the resultant product is constituted by the bis allyl carbonate of the diol together with a quantity of less than or equal to 10% of oligomers represented mainly by dimers. If the ratio is less than 10, the percentage of oligomers rises until, in the case of an approximately stoichiometric ratro, it reaches a value close to 70% of the reaction product.
