Abstract: 1463383 Preparing pigmentary forms of polyhalogeno copper phthalocyanines IMPERIAL CHEMICAL INDUSTRIES Ltd 21 Oct 1975 [11 Nov 1974] 48628/74 Heading C4P A process for the manufacture of pigmentary forms of polyhalogeno copper phthalocyanine prepared by halogenating copper phthalocyanine in an AlCl 3 /NaCl flux comprises mixing the crude halogenation product and flux with more than an equal weight of water containing 0À25-5À0% by weight of a mineral acid, adding a waterimmiscible organic liquid in an amount of from 25-500% by weight of the polyhalogeno copper phthalocyanine to form a two layer system, the polyhalogeno copper phthalocyanine being present with the organic liquid in one layer, the other layer being an aqueous layer which is separated and discarded, washing the residual layer with water, mixing an anionic surface active agent with the residual layer and at least sufficient alkali to render the residual layer alkaline, boiling the residual layer, washing the residual layer with water and thereafter isolating the polyhalogeno copper phthalocyanine. The mineral acid is preferably sulphuric acid and the water immiscible organic liquids are chlorinated hydrocarbons, e.g. mono- and di-chlorobenzenes and aromatic hydrocarbons, e.g. benzene, toluene and xylene. The washing step may be carried out by decantation and the organic liquid may be separated from the polyhalogeno copper phthalocyanine by direct distillation optionally under reduced pressure or by steam distillation. The anionic surface active agent is used in amounts from 1-10% by weight of the polyhalogeno copper phthalocyanine and a non-ionic surface active agent may be added before the distillation.

Title: Polymerization process and products
IPC: C08F279/02
Filed: 1963-12-12
Abstract: Thermoplastic polymeric materials are made by polymerizing at least two monomeric materials having a reactivity ratio other than one in the presence of one or more rubbery polymers, by heating a solution containing up to 20% by weight of the rubbery polymer in at least a portion of the monomers to cause graft polymerization while subjecting the solution to shearing agitation sufficient to maintain the grafted rubbery polymer suspended in the prepolymer in the form of particles not greater than 10 microns in size, until the prepolymer contains from 20 to 50% by weight of solid, adding any remaining monomer, and then continuing the polymerization by heating and agitating the partially polymerized solution suspended in an inert medium, e.g. water, containing a dispersant.  The rubber used is preferably a butadiene polymer, but may also be an acrylate or silicone rubber, an ethylene-propylene-diene terpolymer, polytetrahydrofuran, polypropylene oxide, an allyl glycidyl ether copolymer or a butylene rubber.  Polymerization in the first stage may be effected thermally or by the use of a catalyst such as benzoyl or di-tert.-butyl peroxide.  The suspending medium used in the second stage of polymerization is preferably water containing sodium carboxymethyl methylcellulose as a suspending agent. The examples describe polymerization processes in which the monomer mixtures consist of styrene and acrylonitrile; styrene, alpha-methyl styrene and acrylonitrile; styrene and methyl methacrylate; styrene, methyl methacrylate and either acrylonitrile or methacrylic acid; and acrylonitrile or methyl methacrylate and o-vinyltoluene, mixed m- and p-vinyl toluenes or p-chlorostyrene, the rubbers used being stereospecific polybutadiene, butadiene-styrene and butadiene-acrylonitrile rubbers, and a mixture of polybutadiene and a butadiene-acrylonitrile rubber.

Title: Improvements in apparatus for ejecting a cop tube or like tubular support from a copor like wound package and for inserting a further such tube or support into the tube or package
IPC: D06B23/04
Filed: 1965-11-24
Abstract: In the preparation of yarn cops for a dyeing treatment, the tube on which each cop has been wound is ejected from the cop and replaced by a metal tube of perforate sheet material or spring wire.  The wound cops placed in position on a step-wise rotating table are each in turn halted (a) at an ejecting station where a pneumatically operated tappet strikes the narrow end of the cop tube thereby forcing it from the cop and ejecting it downwardly through a passage in the table whence it is directed by a chute to a collector and then (b) at an inserting station where an overhead "hold-down device" clamps the cop on the turn-table and a pneumatic lifting ram pushes a fresh cop-tube through another passage in the table and into position in the axial passage of the cop.  Fresh tubes are supplied from a continuously rotating magazine beneath the table, each tube being pushed into position on the ram by a feed tappet which is subjtct to the permissive control of a photobarrier which senses the appropriate position of the table.  The cops, with their new tubes, are successively removed from the table by a deflector.

Abstract: 1,180,230. Feeding apparatus. M. R. LOLE. 4 Jan., 1968 [18 Nov., 1966], No. 51677/66. Heading A1M. Apparatus for feeding cows during milking comprises a glass jar 2 for milk extracted from a cow and metering means for supplying a feed ration appropriate to the weight of milk supplied to the jar and automatically operated in accordance with that weight. The jar 2 is suspended by a flexible cord 3 through a spring and damping device 5, and a rigid link 6 with a series of laterally projecting studs 7 which operate a servo-mechanism. In the various embodiments of the apparatus the servo-mechanism can be operated mechanically, electrically or pneumatically or any combination thereof. The servo-mechanism, e.g. a solenoid 14, acts to rotate a corresponding impeller or feed screw 8 in a feed hopper 1 through an appropriate angle to dispense a predetermined quantity of feed. The impeller or feed screw 8 is rotated through a one-way drive mechanism (e.g. a ratchet drive or a one-way drive sprocket) and the impeller or feed screws of a number of the above apparatuses are disposed in a line on a common drive shaft 12 which is rotated constantly during milking, each feed screw remaining stationary unless clutched to the shaft for a selected angular displacement by operation of the servo-mechanism. In a modification the amount of feed dispensed from each hopper can be varied so that the feeding apparatus can be used with feeds of different densities and/or composition. A number of servomechanisms are associated with blocks (27), Fig. 5 (not shown), which are slidably mounted on a common rod (29) guided for longitudinal reciprocatory movement, the movement being attained by means of a variable throw crank (32, 33) so that the amplitude of movement of each block, and therefore the amount of feed dispensed each time the associated servo-mechanism is tripped, is variable.
