Title: Adducts of hexahalocyclopentadiene with alkadienes
Inventor: WEIL EDWARD DAVID
IPC: C07C23/30
Filed: 1965-02-09
Abstract: Compounds of the formula <FORM:1090814/C3/1> <FORM:1090814/C3/2> in which X is a halogen and n has values from 0 to 12 are used to impart flame-retardant properties to polymers.  They may be added to homopolymers and copolymers of olefins, indene-coumarone resins, polymers of acrylic and methacrylic esters, alkyd resins, polyurethanes, polyester resins, natural and synthetic rubbers, styrene resins, terpene resins, urea resins and vinyl resins.ALSO:The invention comprises compounds of formula/sA <FORM:1090814/C2/1> <FORM:1090814/C2/2> in which X is a halogen atom, e.g. chlorine or bromine, and n is from 0 to 12.  They may be prepared by the Diels-Alder reaction between a hexahalocyclopentadiene and the appropriate diene at 40-250 DEG  C.  A mixture of products of the two formulae given above is normally obtained but if equimolar proportions of the reactants are used the product will be almost entirely of the first formula given above, whereas if a molar proportion of hexahalocyclopentadiene to alkadiene of 2 or more is used the product will be mainly of the 2nd formula given above.ALSO:Compounds of formul  <FORM:1090814/A5-A6/1> and <FORM:1090814/A5-A6/2> in which X is a halogen and n has values from 0 to 12 are used as pesticides.  They may be applied in the form of a solution in an organic solvent, e.g. xylene or aromatic naphtha or in water, preferably with an emulsifier or they may be mixed with a conventional solid carrier.  Surfactants, attractants, or other pesticides may also be present in the compositions.

Patent GB-575126-A (GB)
Title: Improvements relating to plastic compositions suitable for filling surfaces of cellular material
IPC: B63C9/08
Filed: 1942-07-30
Abstract: A composition primarily for filling holes or indentations in cellulose structures comprises a viscous solution of a cellulose ester containing the radicles of acetic acid and of a higher homologue thereof, dissolved in a volatile solvent and containing a porous filler, the degree of esterification being such that the mixed ester does not contain more than 0.3 hydroxy groups per C6H10O5 unit. Natural or artificial resins and plasticisers may be added. Specified esters include cellulose acetatepropionate, acetate-butyrate, acetate-stearates, acetate-palmitates and acetate-laurates.  For low specific gravity materials, the filler may be a sawdust of light-weight woods, such as poplar, but beech and oak can also be used, or woodflour, or finely-chopped cotton fibre or kieselguhr, all in proportion about equal to that of the cellulose ester.  When acetone is used as the volatile solvent, from 5 to 20 per cent of colophony, soft manilla, hard manilla and non-thermosetting alkyd resins may be added, calculated on the weight of the cellulose ester.  When benzene is used, colophony, mastic or ester gums may be added. With methyl acetate, colophony, mastic, soft manilla or a non-thermosetting alkyd resin may be added.  As plasticisers tricresyl phosphate, butylphthalyl-butyl-glycollate, or di-butyl phthalate may be used.  The compositions may be used to build up composite sheet materials on a foundation of wire fabric, textile fabric, or mixed with textile fabric, or layers of paper or thin wood alternating with layers of the composition.  In one example, cellulose acetate-stearate having an acetyl value of 39.9 (calculated as acetic acid) and a stearoyl value of 29.0 is mixed with a solvent composed of 95 parts acetone and 5 parts industrial alcohol to give a dope containing 35-50 per cent and preferably 45-46 per cent of the cellulose ester.  Fine poplar sawdust in amount about equal to the ester is then incorporated.

Title: Improvements relating to the calcination of anthracite and like material
IPC: C10B19/00
Filed: 1952-03-06
Abstract: <PICT:0696275/III/1> A process for producing carbon granules by carbonizing anthracite or like carbonaceous material comprises preheating or partly carbonizing a charge of anthracite by means of heat generated by the combustion of gases liberated from the anthracite during the preheating or subsequent complete carbonization and subsequently completing the carbonization by passing electric current through the charge.  The process may be carried out in the apparatus shown in Fig. 1 in which the anthracite is fed from a hopper 5 into an inclined revolving drum 1 in which the anthracite is preheated or partly carbonized.  In the latter case the temperature in the drum 1 is maintained between 800-1000 DEG C and air for combustion of the gases liberated in the drum is admitted through pipes 4 in a quantity such that no excess oxygen is present.  The partly carbonized material passes via a receiver 7 and charging gate 16 to an electric shaft furnace 8 having upper and lower electrodes 9 and 10 wherein the carbonization of the anthracite is completed. Granules of carbonized anthracite are discharged by a rotating platform 13 into a cooling chamber 14 from which they are removed in skips.  If the anthracite is only preheated in the drum 1 most of the volatile constituents of the anthracite are liberated in the shaft furnace 8 and a pipe 11 is provided to conduct the evolved gases to the drum 1.  In a modification the revolving drum 1 is replaced by a stationary vertical chamber provided with inclined baffle plates between which a body of the anthracite is moved downwards to the electric shaft furnace.  The gases liberated in the electric shaft furnace are burnt in a separate combustion chamber and the hot gases are led through the column of anthracite in the preheating chamber. A temperature of 500-600 DEG C is maintained in the preheating chamber.  A furnace with an oscillating grate or one with an endless band grate may also be used for preheating the anthracite.
