Patent GB-728508-A (GB)
Title: Improvements relating to the production of ion-exchange resins
Inventor: SOLT GEORGE STEPHEN
IPC: C08F2/00
Filed: 1952-02-08
Abstract: Ion-exchange resins in particle form are made by causing particles of a cross-linked copolymer, which may or may not possess ion-exchange properties, to imbibe a monomeric liquid mixture of two compounds, containing one and two double bonds respectively and polymerizing the imbibed liquid within the copolymer, the ion-exchange properties or additional ion-exchange properties (if desired) being imparted to the resin after the imbibition.  The particles may result from suspension polymerization or from grinding larger pieces.  The liquid mixture may include a diluent, which may be removed, if desired, after imbibition.  The imbibed liquid may be polymerized while the copolymer is in suspension.  In examples a bead copolymer of styrene and divinyl benzene was (1) chlormethylated, allowed to imbibe a mixture of styrene and divinyl benzene containing benzoyl peroxide and heated in water to polymerize the liquid. The product was swollen in ethylene dichloride, aminated with triethylamine and finally heated with sulphuric acid whereby both quaternary ammonium and sulphonic acid groups were introduced; (2) swollen in ethylene dichloride and heated with sulphuric acid. The sulphonated product was stirred with an aqueous mixture of methacrylic acid and ethylene dimethacrylate containing potassium persulphate, which was polymerized and the product warmed with sodium chloride solution to form a resin containing both sulphonic acid and carboxyl groups; (3) small particles (passing a 52-mesh sieve) of a bead styrene-divinyl benzene copolymer were immersed in a mixture of styrene and divinyl benzene and polymerization effected, resulting in an increase in size of the particles ( 6/7 retained by the 52-mesh sieve).  The ion-exchange properties may be imparted to the resin before and/or after the imbibition.  A batch of particles of low average size may be similarly treated to increase their average diameter and narrow the size range.  The process may also be used to increase the degree of cross-linking by using sufficient monomer containing two double bonds in the imbibed liquid mixture to cross-link the monomer containing one double bond to a greater degree than the original copolymer.

Abstract: 780,935. Stencilling-apparatus. PUTNAM MFG. CO., Inc., F. A. Feb. 6, 1956 [March 31, 1955], No. 3609/56. Class 100(2) In a stencil printing machine having a printing head movable towards and away from a work support, the printing head embodying an ink reservoir the bottom of which is constituted by the stencil, means operating in timed relation with the movements of the printing head are provided to subject the ink in the reservoir to a momentary positive pressure impulse when the stencil has been brought into printing position in contact with the work. The printing head comprises an ink reservoir 14, Figs. 1 and 2, supported on an arm 3, which is movable to bring a stencil 15 ccnstituting the lower wall of the reservoir into and out of contact with the work 18 to the printed resting on a support 2, by means of a toggle mechanism 5, 6, 13 actuated by a crank disc 10 on a drive shaft 11. During the period of contact, the pressure on the ink is first increased to assist the inertia due to the cessation of the downward stroke of the arm 3 in forcing the ink through the stencil, and then a negative pressure is applied to break the ink in the stencil from the imprint, by admitting compressed air first above and then below the piston 20 of a plunger 17 resting on the ink, through solenoid valves 23, 28 controlled by switches 24, 29 actuated by a cam 25 on the disc 10. In another form, Fig. 4, the reservoir 14a is connected successively to a compressed air supply pipe 34 and a vent 36 by means of a valve 30 controlled by a lever 37 operated under the control of an arm mounted on the above-described crank disc or other rotating member carried on the drive shaft.

Abstract: 836,136. Stuffing-box substitutes. VATRIC Ltd. Feb. 4, 1958 [Feb. 4, 1957], No. 3752/57. Class 122 (5). Sealing means for an oscillating shaft 4, particularly the agitator drive shaft of a washing machine, comprises a stationary housing 1 formed with a bore 3 for the shaft and a seating 5 normal to the bore, a first sealing member 13 secured to the shaft and a second sealing member 10 urged into facial sealing contact with the first member by a spring 9 compressed between radially inwardly directed flanges at each end of a rubber sleeve 7, one, 8, of the flanges being bonded to the second member 10 and the other, 6, being pressed by the spring into sealing contact with the seating 5, the second member 10 having on its periphery a lug or lugs 18 that engage a slot or slots 17 in the housing 1 with circumferential clearance thereby allowing a limited degree of rotation of the second member. The members 10 and 13 are preferably of sintered bronze and carbon respectively. The torsional restoring force of the sleeve is normally sufficient to overcome the static friction occurring between the contact faces of the two members at each end of the shaft's oscillation so that the lugs 18 do not contact the walls of the slots 17 but, when the shaft has been stationary for some time or, if for any reason the contact faces stick together, the lugs act to cause slip between the faces by striking the radial walls of the slots after the first movement of the shaft; the seal thereafter functioning normally.
