Title: Process and apparatus for polymerisation of fluid monomers
IPC: B01J8/22
Filed: 1958-05-06
Abstract: A process for catalytically polymerizing at least one olefin in the presence of an inert diluent in a polymerization zone which comprises introducing said olefin into said zone through a plurality of inlets, admixing a portion of the total diluent with said olefin and passing said admixture through said inlets into said polymerization zone and subjecting said olefin to polymerizing conditions in said zone, maintaining a substantially continuous flow of diluent through said inlets into said zone even during periods when the flow of olefin therethrough temporarily ceases.  The catalyst may comprise a minor proportion of chromium oxide associated with at least one porous oxide such as silica, alumina, zirconia and thoria.  The olefin may be ethylene, propylene, 1-pentene, 1-butene or a diolefin, e.g. butadiene.  The diluent may be a paraffinic or cycloparaffinic hydrocarbon and examples are given.ALSO:<PICT:0853324/III/1> The reactants introduced into a conventional polymerization apparatus through a sparger are prevented from blocking the sparger holes in an apparatus in which a monomer such as ethylene is introduced via conduits 10 and 10a to reactor 12 through semi-ring sparger 13.  A suitable fluid diluent is introduced to reactor 12 via sparger 18 and semi-ring sparger 19.  Finely divided catalyst maintained as a slurry suspended in the diluent is introduced via conduit 23 so as to be deposited in a vortex created within reactor 12 by mixing impellers 24 and 25.  Polymer dissolved or suspended in diluent is removed from reactor 12 via conduit 27.  Diluent is passed via conduit 28 into conduit 10a just upstream from the connection of line 10a with sparger 13. The flow of diluent can be controlled within desired limits by the valve in line 28 which will be preferably a globe valve or motor valve so that the amount of diluent will always be in a predetermined ratio to the monomer feed at normal feed rates and so that a minimum amount of flow of diluent will be provided at all times including times of zero monomer feed to prevent blockage.

Abstract: 574,708. Electric resonators. BLUMLEIN, A. D. Sept. 23, 1940, No. 14490. [Class 39 (i)] To reduce dielectric losses due to the inclusion in a hollow resonator of insulating material or of a part of the envelope of an electron discharge device of which the resonator forms part, the insulating material or part of the envelope is disposed so as substantially to coincide with a position of minimum field intensity in the resonator. As shown, a toroidal resonator 2 having a circular constriction 3 and apertures 4, which may be formed as grids, for the passage of the electron stream passes through the wall of the tubular envelope 1 and so includes a portion 1a of the latter. The resonator is so designed that in the case of each of the three portions lying respectively inside the envelope 1, between the envelope 1 and the constriction 3, and outside the constriction, the product of the equivalent lumped capacity and inductance of the inner surface is the same, in which case a position of minimum field intensity occurs in the neighbourhood of the part 1a of the envelope. Preferably, the inductance of the portion outside the constriction 3, and the inductance of the portion between the constriction and the envelope are respectively greater and less than that of the inner portion. Means is preferably provided to adjust the spacing between the walls at the constriction 3. Should the lines of force at the nodal region not be straight, the insulating material may be shaped to conform to them.

Abstract: 1465318 Colour television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 April 1974 [6 April 1973] 14806/74 Heading H4F The frequency of a subcarrier oscillator 1 is initially controlled by the output of a phase detector 13 which receives one input from a frequency divider 7 receiving the output from oscillator 1, the output of frequency divider 7 also being fed via a modulator 17, approximately one-line delay line 57 and demodulator 63 to the other input of phase detector 13. The divisor n of frequency divider 7 is equal to or greater than #f 1 /kf 0  where f 0  is the inverse of the delay time of delay line 57, #f 1  is the maximum deviation of the frequency of the oscillator 1 in the uncontrolled condition from its nominal frequency f 1  and k is the maximum deviation from a desired value of the phase difference between the inputs to phase detector 13 divided by 360 degrees. The values of n, f 0  and f 1  may be chosen to provide a phase difference of 360 degrees between the inputs to phase detector 13 when oscillator 1 is operating at f 1 ; an additional delay may be included in the path of one of these inputs to ensure such a phase difference. Modulator 17 may be a pulse modulator in which case one of the inputs to phase detector 13 may be a sawtooth signal. In the embodiment of Fig. 1, f 1  is twice the subcarrier frequency and n is 567. The circuit may include colour killer switches 25, 73 which are controlled by a circuit 41 receiving separated bursts and the output of a frequencydivide-by-two circuit 49 receiving the output of the oscillator 1. When bursts are being received and oscillator 1 is operating at frequency f 1  switches 25, 73 are switched over by circuit 41, the received chrominance signal being passed via delay line 57, adder 99 and subtractor 101 to demodulator circuit 93 which receives a reference subcarrier input from frequency divide-bytwo circuit 49; oscillator 1 is then controlled by the output of a phase detector 85 receiving separated bursts and a reference signal from frequency divide-by-two circuit 49. n may alternatively be made equal to two.
