Title: Recovery process for polyolefins
IPC: C08F6/02
Filed: 1963-07-16
Abstract: Metallic catalyst residues in polymers obtained by the polymerization of terminally unsaturated olefins with a metallic catalyst, are removed by introducing, into a solution of the polymer in an inert liquid, a quantity of fatty acid at least stoichiometric with respect to the metals in the catalyst residue, and then treating the mixture with an adsorbent, the treatment being effected at a temperature of at least 125 DEG  C.  The acid may be oleic, stearic, or lauric acid, or a coconut fatty acid, admixed if desired with a chelating agent. The adsorbant may be alumina, silica or silica gel.  Preferred catalysts are titanium, vanadium or zirconium halides mixed with a metallic reducing agent such as a metal alkyl or aryl, a Grignard reagent, a metal hydride or an alkali metal.  Those exemplified are titanium tetrachloride, vanadyl chloride, aluminium tri-isobutyl and lithium aluminium tetradecyl.  The polymer may be an ethylene homopolymer, or a copolymer of ethylene with a terminally unsaturated olefin, e.g. butene-1 or decene-1.  The process is preferably one in which the polymer is formed as a solution in an inert hydrocarbon reaction medium.  The polymerization and purification are preferably effected under superatmospheric pressure and may be continuous processes.  The adsorbent may be regenerated with steam. Specification 885,845 is referred to.

Title: Improvements in transfer sheet arrangements, particularly for use in typewriters or the like
IPC: B41J17/00
Filed: 1935-10-16
Abstract: 464,407. Typewriters &c. DOUGLAS, W. Oct. 16, 1935, No. 28584. [Class 100 (iv)] Carbon-sheet arrangements.-In a set of carbon transfer sheets each sheet is provided with a lateral extension at only one lateral border whereby the sheets are adapted to be secured together, and means on each sheet for enabling it to be held along a transverse border by a laterally engaged device. In one form, the carbon sheets are secured together at one side by such means as staples, spring clips, or press-stud fasteners which engage lug extensions on the sheets. A transverse marginal portion of each carbon sheet is folded over and secured by adhesive or otherwise to form a transverse loop to be engaged by a transversely disposed member on a typewriter or the like. In another form, carbon sheets, as above described, are secured to a backing sheet or strip, some at one lateral border or edge of the strip, and the others at the opposite lateral border. Fanfolded and interfolded record webs can be interleaved with either arrangement. In the form shown in Fig. 5, there are eight carbon sheets b, and uncarbonized paper sheets e. The sheets e are directly attached to a backing sheet a, four at one side and four at the other, by means of adhesive tape c placed over a number of superposed holes b<1> in the sheets e and adhering to the backing sheet a through these holes. Each of the sheets e is attached by means of adhesive tape c<1> to a transverse border of a carbon sheet b, the sheets e being folded over to form transverse loops f. Thus the carbon sheets b are indirectly attached together and to the. backing sheet a, and their carbon surfaces protected, by means of the sheets e, and the sheets e are perforated so that portions may be readily removed when the assembly is required for use. To anchor the carbon sheets or to enable them to be retracted, according to the kind of typewriter, blades g, Fig. 8, are inserted in the loops f. The blades g are in two sets, one at each side, and are secured in stepped formation on stepped blocks i removably secured on a base-plate l resting on the rails h of the machine, the arrangement being such that the blocks i, with the blades g, can swivel slightly for adjustment of the carbon sheets. In use, the blocks i are removed, and the two sets of blades g are inserted in the loops f of the carbon sheets, one set from one side, and the other set from the opposite side. The baseplate l will be stationary or slidable according as to whether the typewriter is of the flat bed or of the cylindrical platen type. Where fanfold record webs are used, the blades g could be adjusted in length so as to slit the folds thereof when the blades are retracted.

Title: Improvements in and relating to the measurement of x-radiations
IPC: G01T1/15
Filed: 1922-10-20
Abstract: 207,672. Phillips, C. E. S. Oct. 20, 1922. Actinometers.- An instrument for measuring the intensity of X-rays by measuring the rate of loss of charge of a fixed surface exposed to the ionizing effect of the rays comprises an oscillating electrostatic system adapted to charge the fixed surface at each oscillation, the period of oscillation being utilized for indicating or integrating the intensity of the rays. In the construction shown, the moving system consists of a rocking arm k of phosphor-bronze wire, one end m being turned down and the other end being attached rigidly to a light disc n of copper foil, which has a perforation through which one end of a wire spring r projects. The arm k is suspended in an horizontal plane by a cross wire stretched between two metal columns c mounted on a metal base a. Beneath the moving disc h is arranged a fixed graphite-coated plate h mounted on an insulating column e and connected electrically to a plate in the ionization chamber (not shown). Beneath the turned-down end m of the arm k is arranged a graphite block f, which is adjustably mounted on a metal block g carried by an insulating column d. The moving system is maintained at a potential of, for example, 300 volts by means of a battery, and a battery and relay are connected between the block f and the column c, the apparatus being enclosed in a lead casing w, x. The operation is as follows. The movable disc n, being charged, is attached to the disc h and charges this and the plate in the ionization chamber. Repulsion between the discs n, h ensues, aided by the spring r, the point m then making contact with the block f and closing the circuit of the relay, which operates a bell, lamp &c., or an indicating or integrating instrument. The charge on the fixed system is dissipated at a rate depending on the intensity of the X-rays, and when the charge has fallen to a definite magnitude the disc n is again attracted to the plate h and the cycle of operations recurs. The graphite block f and disc h should preferably be coated with fine powdered charcoal. In a modification the arm carrying the moving disc n is arranged vertically and the other arm horizontally dipping into a mercury cup in place, of the graphite block f. Disengagement from the mercury is assisted by an electromagnet having an armature with a resilient finger which bears upon the rocker arm.
