Patent GB-463637-A (GB)
Abstract: 463,637. Typewriters &c. NATIONAL CASH REGISTER CO. Oct. 2, 1935, No. 27159. Convention date, Oct. 2, 1934. Addition to 461,423. [Class 100 (iv)] [Also in Group XIX] Tabulating-mechanism; carriage-returning mechanism.-In a machine as described in the parent Specification with a travelling carriage and means for arresting the carriage in predetermined columnar positions on the return movement, the arresting means instead of being under the control of manipulative means is conditioned for this purpose automatically prior to the commencement of the return movement. As shown in Figs. 1 and 2 the carriage rail 333 in addition to the stops 332 carries a setting member 500 with wings 501, 503. Near the end of the movement of the carriage in the normal tabulating direction the wing 501 contacts the projection 330 of the stop lever 324 and moves it into the path of the stop 332. The stop lever, through its pivot 323 and spring connection 325, imparts movement to the lever 322, the parts being held in position by a detent 337. When the carriage reaches the end of its travel the return mechanism is automatically operated to return the carriage. At this time the wing 503 is to the right of the projection 330, so that, if the lever 324 has been restored to inoperative position by the operation of the link 313 by depression of a return bar (not shown), the wing 50 on the return movement will again move the lever 324 into the path of movement of the stop 332 and the carriage will be arrested in the position determined by the stop.

Title: Method of preparing a polymer salt
IPC: C09K23/42
Filed: 1965-11-08
Abstract: Water-soluble polymer salts are produced by emulsion polymerization of an alkyl ester of an a -methylene monocarboxylic acid in an aqueous system containing an alkyl or alkaryl mono-, di- or polyoxyethylene phosphate as emulsifier and hydrolysis of the resulting polymer with at least one alkali metal hydroxide, the mole ratio of hydroxide to polymer being from 0.5:1 to 1.2:1. Suitable esters are of formula <FORM:1077889/C3/1> wherein R1 is hydrogen, or R, and R is an alkyl radical of 1 to 3 carbon atoms, e.g. methyl, ethyl and propyl(meth)acrylates. The alkyl and alkaryl polyoxyethylene phosphates are of formulae <FORM:1077889/C3/2> wherein R1 is an alkyl group of 8 to 27 carbon atoms, R2 is an alkyl radical group of 5 to 27 carbon atoms, or a cycloalkyl group of 5 to 10 carbon atoms, R3 and R4 each represent hydrogen, an alkyl group of 1 to 22 carbon atoms or a cycloalkyl group of 5 to 10 carbon atoms, n is an integer from 1 to 60, x is 1 or 2 and each m represents hydrogen, ammonium or an alkali metal.  m May also be an organo-substituted ammonium radical.  The preferred emulsifiers are produced by adjusting Me pH of the acid alkyl or alkaryl polyoxyethylene phosphate to 5 to 7 with the appropriate alkali metal or ammonium hydroxide. Polymerization of the alkyl ester is effected in a medium of pH e.g. 1.5 to 8.5, the pH being adjusted with NaOH, KOM, sodium acetate or HCl.  Conventional free radical catalysts, e.g. inorganic persulphates and organic peroxides are used, optionally with a mercaptan modifier.  The resulting polymer emulsion is hydrolysed with an aqueous solution of e.g. LiOH, NaOH, KOH or mixtures thereof, a stabilizer such as a polyoxyethylated alcohol being included in the solution if desired.  The polymer salts thus produced are used as thickeners for aqueous dispersions of natural and synthetic polymers, examples being listed.  In the examples, methyl acrylate is polymerized in aqueous systems containing partial sodium salts of nonyl- or di-nonyl-phenoxypoly (ethyleneoxy) phosphates asemulsifier and sodium bisulphide and potassium persulphate as catalysts.  The polyacrylates produced are hydrolyzed with a mixture of LiOH and NaOH or with NaOH or KOH alone and the resulting polyacrylate salts are used to thicken latices of butadiene-styrene-carboxylic acid polymers.

Headings B8C and B8F. Flattened cartons, removed from a magazine, are erected into tubular shape by grippers acting upon the end closure flaps. The rear edge 15, Fig. 2, of a flattened carton, having bottom end closure flaps 7 to 10, and top end closure flaps (7<SP>1</SP>) to (10<SP>1</SP>) to form the base and top end, respectively, is contacted by a flight 16, Fig. 3, of a conveyer 13 and pushed as far as a position 17 whereat the conveyer stops. During the carriage, the flaps 8, (8<SP>1</SP>), 9, (9<SP>1</SP>) are lifted by fixed ramps 21, 22 respectively after sliding up movable ramps 23, (23<SP>1</SP>), respectively. Pressure members 26 on a system rotatable about a point a then bear on a side face 5 of the carton to press the side walls of the carton back on to the conveyer to cause flaps 8, 9, (8<SP>1</SP>) and (9<SP>1</SP>) to be lifted by reaction against the ramps. Grippers 27, also on the system, move to engage the flaps 9, (9<SP>1</SP>) where they are not overlapped by the flaps 8, (8<SP>1</SP>). Dogs 28 clamp the flaps 10, (10<SP>1</SP>) against plates 24 at positions where they are not overlapped by flaps 7, (7<SP>1</SP>). The ramps 23, (23<SP>1</SP>) retract and the system rotates anticlockwise to erect the carton by raising the flaps 9, (9<SP>1</SP>) relative to the flaps 10, (10<SP>1</SP>). When the carton is erected, levers move to close flaps 7, (7<SP>1</SP>), 8, (8<SP>1</SP>). When the ramp 23 returns to its former position, the carton is pushed by conveyers 13 and 32 and the flaps 9, 10 at the bottom end of the cartons are folded inwards by reaction against ramps 21, 33. Ramps 22, 34 cause flaps (9<SP>1</SP>), (10<SP>1</SP>) at the opposite top end to be folded outwardly to rest against faces 5 and 6. An adhesive strip 35 is then applied across the flaps 9 and 10 and the carton is delivered to a rocker unit 38 which rotates about a pivot b to discharge the carton either for direct use or to a station to fold the flaps (7<SP>1</SP>), (8<SP>1</SP>) outwards.
