  • Patent number: 7691297
    Abstract: In a process for the manufacture of beadlet preparations of fat-soluble substances in a water-soluble or water-dispersible non-gelling matrix, an aqueous emulsion of the fat-soluble substance(s) and the matrix component are fed through a spray nozzle in the upper section of a vertical spray tower. Through separate inlets powderous starch and a stream of hot air are also fed in the upper section of the vertical spray tower. A stream of cold air is fed in the lower section of the spray tower so as to form a fluidised bed of starch-covered beadlets comprising the matrix component as well as the fat-soluble substances. The beadlets are collected from the fluidised bed and are discharged to a dryer.

  • Patent number: 4864488
    Abstract: A power supply for producing a single level D.C. output voltage in response to a 110 or 220 A.C. input voltage is disclosed. The power supply automatically selects a full wave diode bridge or voltage doubler configuration and provides series capacitors to filter the D.C. output voltage. The selection is controlled by a switch which responds to the charge on one of the output capacitors. Latching means are also provided to prevent the power supply from switching to the voltage doubler configuration once 220 volts is applied.
