Title: Preparation of amphoteric ion exchange resins
IPC: B01J43/00
Filed: 1973-01-17
Abstract: 1407116 Producing amphoteric ion-exchange copolymers COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION and ICI AUSTRALIA Ltd 17 Jan 1973 2393/73 Heading C3P Amphoteric, thermally - regenerable, ionexchange resins are obtained by simultaneously polymerizing acidic and basic monomers and also, if necessary to form a cross-linked structure, cross-linking monomers, in a homogeneous aqueous solvent system under conditions which inhibit self-neutralization between the acidic and basic moieties in the forming resin, e.i. by neutralizing the monomers before polymerization and/or by providing suitable counter-ions in the polymerizing mixture which associate more strongly with the anionic and cationic moieties of the monomers than such moieties associate with one another. The acidic monomers are unsaturated carboxylic acid or anhydrides thereof, while the basic monomers are allylamines, N-alkyl-ethyleneimines, dimethylaminoethyl acrylate or methacrylate and t-butyl aminoethylacrylate or methacrylate. The product resin may be subjected to simple treatments to remove the counter-ions and to effect pH equilibration. The ion-ecxhangers may be used in waterpurification, e.g. to remove divalent ions, such as calcium cations. Acidic monomers mentioned are acrylic acid, methacrylic acid, maleic anhydride, vinyl-acetic acid and allylacetic acid. A wide variety of counter-ions are mentioned including the usual metal cations and inorganic anions and also certain organic cations, e.g. and anions, e.g. CH 3 COO-. In the examples, sodium acrylate / triallylamine hydrochloride or sulphate, benzyltrimethylammonium methacrylate/triallyl ammonium hydrochloride, sodium methacrylate/dimethylaminoethyl methacrylate / ethylene glycol dimethacrylate, and acrylic acid/triallylamine were copolymerized using persulphate initiator or irradiation, in the presence of small amounts of water and, in some cases, dimethyl formamide, and in the presence of the following added counterions, which addition is omitted in some examples where both initial monomers are already neutralized, SO4, Na + Cl, Ca + Cl, K+SO 4 , Cl+SO 4 , Mg+Cl, Sr+Cl, Ba+Cl, Zn+Cl, Mn + Cl, K+C 2 H 5 COO and Na+C 4 H 9 .COO.

Title: Timepiece movement
IPC: G04B27/00
Filed: 1972-01-19
Abstract: 1380492 Geographical and universal timepieces SUWA SEIKOSHA KK 19 Jan 1972 [5 Feb 1971] 2545/72 Heading G3T A timepiece movement has a clutch for transmitting drive between two hour hand wheels, said clutch comprising a spring which engages both wheels and urges them into a selected one of a plurality of relative angular positions without acting as a friction brake when the movement is running. As shown, a timepiece capable of displaying time in two different time zones by a second hour hand 15, which is additional to'conventional hour, minute and seconds hands 13, 12, 11, has means for simultaneously correcting the two sets of hands and means for correcting hand 15 with respect to the other hands in steps of 30 minutes or of 1 hour. Tubular member 20 has 12 or 24 teeth 22 engaged by an end portion of a C-shaped jumperspring 30 whose other end is secured to tubular member 21, the parts 22, 30, thus constituting a slipping clutch which normally transmits the drive transmitted to member 20 from minute wheel 16 to member 21 and second hour hand 15. Correction of hand 15 only is by rotation of a stem (34), Fig. 3 (not shown), which rotates a correction transmitting wheel 27. Rotation of stem (34) in the opposite direction may adjust a calendar member (35). Axial movement of stem (34) inwardly from this position allows winding of a main-spring, while axial movement outwardly from the middle position allows simultaneously movement of hand 15 and hands 11-13 upon rotation of the stem. A further embodiment Fig.4, utilizes the pins 43 in a flange 42 of member 21 engaging selected ones of 12 or 24 recesses or apertures in a gear 23 secured to member 20, under the force of a spring 45, to form an alternative clutch arrangement. The hour hands may be incorporated in a quartz crystal oscillator or tuning fork oscillator watch. When stem 34 is in a position to adjust hands 11-13, the seconds hand 11 may be stopped by a mechanism (not shown).

The shafts 6, 23 are connected by a chain 30 passing round sprocket wheels 28, 29 so that rotation of shaft 6 to select type on wheel 7 is transmitted to wheel 24. Letter-spacing.-A pawl 14, Fig. 2, engages a ratchet wheel 15, Fig. 1, on upward movement of the handle 10 after an impression to rotate feed rollers (18, Fig. 5, not shown) and advance the paper under type wheel 7. Such rotation is transmitted by a chain (46, Fig. 5) to a further pair of feed rollers 20, Fig. 1, to advance the paper under type wheel 24. The feed rollers 20 may rotate by smaller increments, the wheel 24 being smaller than wheel 7, a recess (48, Fig. 7, not shown) taking up a sag in the paper. Paper feed may be prevented for printing of characters such as comma by a pin 12, Fig. 2, disengaging the pawl 14 from the ratchet wheel 15. Inking-arrangements.-Ink pads (57, 62, Fig. 10) apply ink to the selected type characters on the wheels 7, 24 respectively, and are displaced as the wheels are lowered for impression by a pin (58) on a rotatable plate (53) carrying the pad (57) engaging a slot (59) on a fixed bracket (60).

An unshaped flat band tyre carcase is formed by disposing a pocket of carcase ply fabric around a pair of coaxial, spaced, radiallyexpansible bead core-gripping members 3 with the central portion of the pocket unsupported and enclosing the space between the members 3 and the ends of the pocket extending axially outwardly beyond the members 3, positioning bead cores 22 to be gripped by expansion of the members 3 and then turning over the ply ends around the bead wires on to the centre portion by means 4 associated with each member 3. The space 33 between the members 3 is pressurized via pipe 34 to support the otherwise unsupported centre portion of the ply during the turn-over operation, which is effected as shown by the means described in Specification 884,513. The bead-gripping members 3 comprise rigid supports 5 each slidably mounted on a shaft 1 with its inner periphery recessed to form a double-acting cylinder 7, 8 co-operating with a fixed piston member 9 on the shaft 1, ducts 10, 11 providing for selective supply of pressure fluid to the chambers 7, 8 to effect approach or retraction of the supports 5.

Abstract: 617,864. Magazine gramophones. METCALFE, C., and RAE, A. J. Feb. 17, 1944, Nos. 2936 and 25699. [Class 40 (ii)] Records stacked on a shoulder 12 of a post 10 extending above the turntable 11 are released one at a time by a projection 16 on a rotatable sleeve 15, the projection engaging the centre hole in the lowermost record to displace the record when sleeve 15 is rocked from a sleeve 24 driven from the automatic mechanism. Sleeve 15 may be slidably mounted so as to yield against the action of a spring 22 under the weight of a record remaining in the magazine after the bottom record has been displaced, so that the stack always sits squarely on shoulder 12. The stack may be steadied by an arm which drops when the magazine is exhausted to stop the machine when the last record has been played. Preferably, it is arranged that when the machine is switched off, sleeve 15 is moved into record feeding position to displace a record as soon as the machine is started again. The upper part 17 of the post 10 is made removable to facilitate the lifting of played records from the turntable. Specifications 520,941, 552,546 and 554,530 are referred to.
