Abstract: 1490227 Flotation apparatus; dispersing gases in liquids PIELKENROOD-VINITEX BV 6 Dec 1974 [22 Dec 1973] 52771/74 Headings B1C B1D and B2H A method of separating suspended material from a suspension comprises reducing the pressure of a pressurized liquid containing gas or a volatile substance to form a dispersion of gas bubbles in the liquid, and introducing the liquid into a tank containing the suspension and forming part of a plate-type separator 7 so that the bubbles become attached to the suspended material and cause it to float. In the embodiment shown the suspension is introduced to a chamber 3 through a duct 11 and a nozzle 12, the latter consisting of a tube having a longitudinal slot. A pump 16 draws in air through a pipe 18 and liquid through a pipe 17 and produces a pressure in a pipe 14. This pressure is suddenly relieved beyond a valve 15 to produce a dispersion of air bubbles in the liquid which is injected into the chamber 3 through a nozzle 13. Floating material passes over a weir 5 into a discharge chamber 6 and sediment is collected in a hopper 10 after passing through an assembly 7 of superposed parallel corrugated plates. In another embodiment, Fig. 3 (not shown) there are separate pumps (16) and (21) for the liquid and air which may be stored under pressure in a mixing vessel (22) before passing through the valve 15. The suspension to be treated and the dispersion of gas bubbles in the liquid may be introduced into the chamber 3 through the same nozzle, and in another modification the suspension itself is pressurized and mixed with air to form the dispersion of gas bubbles. The suspension may be subjected to a coalescence treatment in a device located either inside or outside the chamber 3.

Abstract: The present invention relates to an alpha-olefin prepolymer catalytically active in an alpha-olefin (co-)polymerization comprising a transition metal, an organometallic compound and an antistatic agent. The prepolymer can be prepared by contacting the antistatic agent with a catalyst comprising the transition metal and the organometallic compound before or during an alpha-olefin prepolymerization. It can also be prepared by contacting the antistatic agent with an alpha-olefin prepolymer after a prepolymerization. It can also be prepared by a combination of the two methods. The prepolymer can be introduced into a gas phase (co-)polymerization medium for preparing polyolefin directly in a dry powder form, with a reduced amount of sheeting and agglomerates.

Abstract: A high-speed random number generator (1) comprising a physical random number generator, having a data input, an output and a pseudo-random generator coupled to the output of the physical random generator. The pseudo-random generator has an input adapted to receive a germ delivered by the physical generator and deliver at an output a pseudo-random output signal. The physical generator comprises a logic circuit that includes at least a data input (D) and a clock input (CLK), the data input (D) receiving a first "high frequency" clock signal H1 and the clock input (CLK) receiving a second "low frequency" clock signal H2, with the "high frequency" signal H1 being sampled by the "low frequency" signal H2. The two clock signals H1 and H2 are of different frequencies respectively and issue from two different first (OSC1 and OSC2) operating asynchronously from one another and not adhering to the setup time of the logic circuit (10). The logic circuit is arranged to deliver at an output a signal in an intermediate state qualified as metastable between "0" and "1" and being constituted by a random number sequence. The metastability of the signal obtained as an output from the logic circuit (10) is accentuated by phase noise of the first oscillator (OSC1) generating the "high frequency" signal H1. The pseudo-random generator is arranged to re-inject part of the pseudo-random output signal into the physical generator. An internal memory stores the random numbers obtained as output signals from the pseudo-random generator. The two generators run on the same second "high frequency" clock H generated by the external oscillator (7).
