  • Patent number: 4597869
    Abstract: In the particular embodiment of the invention described in the specification, a plate pack for an inclined plate separator has plate support members forming the side walls of the separator in which the separation plates are received in grooves formed by converging tongues. The support members are releasably joined together edge to edge by a bead projecting from one edge of the support member and a groove formed in the adjacent edge of the next supporting member.

  • Patent number: 4392422
    Abstract: In the embodiments of the web press disclosed in the specification, a pair of webs carries suspension material partly about a series of press drums of decreasing diameter in a first pressing section. One of the webs carrying the suspension material passes to a second press section where a further web replaces the other of the pair of webs to provide the inner web in a path around a press drum. Increased pressure is applied by a pressure belt to the webs as they pass around the press drum in the second pressing section.
