  • Publication number: 20200231387
    Abstract: A conveying device (1) has conveying carts (2) arranged one behind another and spaced apart by an interspace (4). One conveying cart (2) has a cover (6) and another has a cross-belt conveyor (8) for conveying material transverse to the conveying direction. The cover (6) covers the interspace (4) between the conveying carts (2) so that the cover (6) of the one conveying cart (2) is under the upper run (21) of the transverse belt (10) of the other conveying cart (2). When negotiating curves, the cover (6) engages between an underside (22) of the upper run (21) and a first support plane (20) to hinder the transverse belt (10) from moving in the transverse conveying direction. When travelling straight ahead the cover (6) engages between the first support plane (20) and a second support plane (24) to permit movement of the transverse belt (10) in the transverse conveying direction.

  • Patent number: 6482385
    Abstract: Sodium percarbonate is traditionally made in a crystallization process from aqueous hydrogen peroxide and sodium carbonate with recycle of mother liquor in the presence of a substantial concentration of a salting out agent, conventionally sodium chloride. The invention provides a process intended to be conducted without addition of chloride salting-out agent in which the dissolution step is controlled to restrict the sodium carbonate concentration to below 95%, preferably 60 to 90% of its saturated concentration at a temperature preferably controlled to at most 35C. and the mole ratio of hydrogen peroxide:sodium carbonate in the reaction vessel is controlled to between 0.7 to 1.2:1, and preferably about 1:1.
