Abstract: A discontinuously operated centrifuge, in particular sugar or starch centrifuge, includes a rotating, cylindrical centrifuge basket having a casing provided with openings and having an upper open end. An inner screen element formed as a composite unit of a screen mat and a support mat is insertable as a prefabricated, single-piece screen element into the centrifuge basket via the upper open end thereof. The screen element has ends abutting in a circumferential direction within the centrifuge basket, with axially extending end strips attached to the abutting ends of the screen element. A closure element in the form of an axially extending clamping strip cooperates with the end strips so as to lock and radially brace the screen element against the centrifuge basket casing. Attached on the centrifuge basket is an upper limiting flange, with an annular cover being screwed onto an upper limiting flange for securing the screen element.

Abstract: Corrugated screen filters and related method of fabrication whereby an available filter surface is increased so as to allow an increase a flow capacity of the corrugated screen filter. The corrugated screen filter can comprise a plurality of rods forming a series of alternate and angular ridges and grooves on a surface of the filter screen. The filter screen can be configured to have longitudinal corrugations only on an exterior surface of the filter screen or alternatively, the filter screen can be configured to have longitudinal corrugations only on an interior surface of the filter screen. The alternate angular ridges and grooves can form corrugations in a variety of configurations including, but not limited to, a sinusoidal wave structure, a triangular wave structure, a rectangular wave structure, a trapezoidal wave structure, or the like.

Abstract: A duplex optical fiber connector terminates two single or multi-mode optical fibers of a cable and is adapted to be joined to a receptacle being polarized correspondingly to a keying element of the connector. The keying element is slidable into multiple positions so that a recess in the keying element mates with a correspondingly positioned rib of a receptacle. The recess of the keying element is positioned within a channel axially extending on the connector exterior body.
