Abstract: A receiver aboard a communication satellite, designed to detect digital signals arriving in intermittent bursts from a ground station with a bit cadence differing but slightly from a clock frequency f.sub.s generated by a time base on the satellite, comprises a synchronizer controlled by that time base for reorganizing the detected bits into a data frame in step with clock frequency f.sub.s preparatorily to processing and retransmission thereof. The synchronizer samples a square wave of frequency 2f.sub.s substantially at the midpoint of an initial bit period of an incoming signal stream, with the aid of a timing signal extracted from that signal stream, and determines from the sample whether this square wave or an inversion thereof is to be used in establishing the instants of reading of the subsequently received bits. The bits thus read, after interim storage in two cascaded registers, are fed to a data processor in the rhythm of clock frequency f.sub.s.

Abstract: An apparatus for separating fluids is formed essentially of three pieces which may be nested together to form a stacked array. The three pieces are a cap, an extraction cartridge housing a separating column, and a primary recovery cup. A secondary recovery cup may also be nested onto the lower end of the waste cup. The primary recovery cup has interior flanges for positioning and protecting the bottom end of the column against damage. Each of the elements has an enlarged upper portion forming an exterior step which facilitates mounting in the swinging bucket of a centrifuge. The column itself may comprise particles of a suitable separatory material with the top and the bottom of the particles retained by porous supports.
