Title: Process for the production of polyethylene with a high melting point, by means of ethyl aluminium sesquichloride and titanium tetrachloride
Inventor: ANTON ELISABETH
IPC: C08F110/02
Filed: 1964-06-17
Abstract: Polyethylene is made by polymerizing ethylene in the presence of a catalyst comprising ethyl aluminium sesquichloride and TiCl4 in a molar ratio of between 8:1 and 20:1, by introducing the catalyst components directly into the polymerization reactor, reacting them, before polymerization, in an inert atmosphere, and for a time sufficient to ensure reduction of the TiCl4.

Title: Improvements in the manufacture and production of anthraquinone and homologues of the same
IPC: C07C46/02
Filed: 1929-08-19
Abstract: Anthraquinone and its homologues are obtained by treating the condensation products from 1 molecular proportion of benzoquinone and 2 molecular proportions of the same 1 : 3-butadiene, or the rearrangement products thereof, or the tetrahydroanthrahydroquinones, tetrahydroanthraquinones or corresponding quinhydrones obtainable therefrom by mild dehydrogenation as described in the parent Specification, with a metal salt, the cation of which is capable of assuming a lower valency, e.g. a ferric, cupric or mercuric salt, in an acid medium.  The metal salt may be employed in quantities at least equal to those theoretically necessary for the conversion into anthraquinones, or smaller quantities may be employed if the reaction is carried out in the presence of agents, such as oxygen or air, capable of reforming the cations of higher valency.  The concentration of the acid may be varied within wide limits; in some cases the acid produced by hydrolysis of the aqueous solutions of the metal salts is sufficient.  In examples (1) the condensation product from benzoquinone and 1 : 3-butadiene (2 mols.) is heated with ferric chloride in glacial acetic acid to form anthraquinone, (2) the rearrangement product described in example 29 of the parent Specification is heated with a solution of ferric chloride, ferric sulphate, cupric chloride, or mercuric acetate under pressure to form anthraquinone; other cupric salts such as cupric acetate may also be used, and acids, such as acetic acid, may be added to the solutions, and (3) the condensation product from benzoquinone and isoprene (2 mols.) is heated with ferric chloride solution under pressure; 2 : 7-dimethylanthraquinone is formed.

The computer circuit comprises a saw-tooth wave generator responsive to pulses S c  to produce a ramp pulse S e  of shorter duration than the time interval between successive S c  pulses and a risetime concurrent with the S c  pulses, a comparator which compares the analogue signal Va with the ramp pulse S e  to produce a square-shaped pulse Sf when the former is higher than the latter, and a logic circuit for passing pulses Sb to the counter 34 in the presence of the squareshaped pulses Sf. The counter 34 produces as a basic signal a potential E o  proportional to the number m of Sb pulses registered in the memory circuit 32 during each of the time intervals and adds a predetermined potential thereto for each Sd pulse, to deliver the spark-advance signal when the sum of the potential reaches a predetermined value Ep. Again, the basic potential may be proportional to the reciprocal of m, and each Sd pulse subtracted therefrom until the potential is zero. The detector 24 comprises a disc (38), Fig. 5 (not shown), having two rings (42), (44) mounted on its circumference, one (42) having permanent magnets (46) equiangularly spaced around it, the number of which is half the number of engine cylinders, and the other having a plurality of north and south pole sections disposed alternately around its entire circumference and two electromagnetic pick-ups (48), (50) associated with the rings.

Binary digital words, from sensing apparatus 2, which represent two different kinds of information are sorted into two registers 44 and 48 by entering them into a shift register 8 by supplying a " low " signal at 24 to open gate 4, and subsequently entering them into the shift registers 44 and 48 by feeding the contents of 8 to both and arranging that the appropriate register receives shift pulses from a generator 20 through gate 41 or 47 when the signal at 24 is switched to " high," the shift pulses being gated according to the output from a circulating register 34 containing the sorting programme. As shown, the output of 2 consists of alternate 3-bit B- words and 2-bit A-words, and the register 34 has been filled accordingly at 60 so that while A-words are being read out on line 14, " 1 "s on line 40 open gate 47 and close 41, and vice versa for the B words. The above has assumed that a " low " input has been applied to 58 to open gates 53 and 55 and close 54 and 56; if the signal at 58 is " high " during a " high " " compact and transfer signal at 24 then shift pulses from 20 will read out words from the registers 44 and 48 and re-enter them into 8 according to the contents of register 34, which may previously be changed to enter all the A- words first, and then the B-words. The shift registers 8 and 34 may be replaced by storage tracks on a magnetic drum. Specification 794,633 is referred to.
