  • Patent number: 6518443
    Abstract: The oil seed is first of all comminuted and then formed into flakes by means of rolling, before it is supplied to the recovery of oil. The flakes are charged into a transporting mixer, to which steam and/or water are supplied at the same time, and the flakes in the mixer are transported to the outlet of the mixer with a dwell time of 5 to 50 seconds. With a moisture content of 8 to 20 wt-% and with temperatures in the range from 90 to 110° C., the flakes are withdrawn from the mixer and passed through an annealing zone, in which the flakes are moved over heated trays with dwell times of 15 to 50 minutes and temperatures in the range from 90 to 110° C. The flakes are withdrawn from the annealing zone with a residual moisture which still amounts to at least half the moisture content at the inlet of the annealing zone, and are passed through a drying and cooling zone in which the flakes are converted to granules which are supplied to the recovery of oil.

  • Patent number: 6390373
    Abstract: A chip card comprising a memory chip and/or processor chip is characterized by the presence of a mirror memory to which any new internal stored data are transferred by an external read or write device whenever the memory chip and/or processor chip carry out an operation. The mirror memory thus has stored data corresponding to the stored contents in the memory chip and/or processor chip, and an LCD display or similar device with a voltage supply from at least one solar cell or the like. The mirror memory is lined to the LCD display or similar device with a voltage supply from at least one solar cell or the like. The mirror memory is linked to the LCD display in such a way that the data stored in said memory can be displayed by the LCD display.

  • Patent number: 5059191
    Abstract: A method and an apparatus for the substantially uniform irradiation of the entire area of cavities from the inside. The apparatus comprises a light source and a layer comprising a material having a high-scatter capability, low transmission and low absorption, wherein said layer fits well to the interior surface of a cavity. The method comprises placing an area-covering layer along rhe cavity wall of the cavity to be irradiated with a material having a high diffusive reflection capability, low transmission, and low absorption capability to obtain a lined cavity; introducing a light source onto the interior of the lined cavity; and irradiating the lined cavity so that the light entering from the area-covering layer into the cavity wall is homogeneously distributed.
