Title: Apparatus for making bags of paper or like on a bottom making cylinder
IPC: B31B29/00
Filed: 1959-12-03
Abstract: 938,857. Paper bag making machines. A. WINDMOLLER, and M. GENNERICH. Dec. 3, 1959 [Dec. 12, 1958; Dec. 24, 1958], No. 41165/59. Class 94(2). A machine for making block bottom bags comprises a rotatable bottom-forming cylinder 6 which conveys gussetted tube sections 118 from which the bags are made in the direction of their length, means 15, 21 for forming bottom closing flaps 129, 126, and a pair of folding tools 18, extending inwards from opposite ends of the cylinder and rotatable therewith, which are pushed under the trailing closure flap 126 and then moved forwardly relative to the tube section to fold the trailing flap 126 forwardly about the line 125. Each finger 18 extends from a two-armed lever 41 42 pivoted at 43, the end of the arm 42 sliding along a cam disc 44. The pivot 43 is carried by another two armed lever 45, 46 pivoted at 47, the end of the arm 47 sliding along a second cam disc 48. The pivot 47 is slidable longitudinally and its end bears under spring pressure against a third cam disc 50. The fingers 18 can thus move in three dimensions i.e. radially, circumferentially and parallel to the axis of the bottom forming cylinder. The laterally gussetted tube sections are fed at 1, Fig. 1, from a cutter and led to the cylinder 6 by discs 2 and roller 3. The upper wall of the tube section is grasped by a sucker 7 and lifted while grabs 8, 9 open out the gussets in cooperation with roller 20. The flaps 121, 122 of the bottom are folded down by tools 15, 21 and the fingers 18 place themselves on the tube behind the folding line 125 of the trailing closure flap leaving the flap 126 free. Paste 127 is applied by member 23 and the leading flap 129 is creased by a knife 25. The fingers 18 then slide further on to the bag and get underneath the trailing closure flap 126 which is slightly raised due to the curvature of the cylinder. Folding line 125 of the trailing flap 126 is defined by a tool 126, the fingers 18 are lifted, the tool 126 raised and the fingers 18 moved forward and then lowered to fold the trailing flap on the line 125. A tool 27 turns over and holds down the leading closure flap 129 and the bag is removed by a take-off cylinder 29, the fingers 18 lifting off the bag and returning to their initial positions during the remainder of the revolution of the cylinder 6. The transverse folds are restricted to the upper wall of the bag tube, the lower tube wall and the lower parts of the gussets having no transverse preliminary folds so that the front of the bag shows no fold lines and printed matter on this face will not be affected. To adjust the machine for bags of different sizes the end discs of the cylinder which carry the folding tools are moved towards or away from each other by screw mechanism, see Specification 938,858.

Patent GB-1026706-A (GB)
Title: Improvements in or relating to cellulose derivatives
IPC: C08B11/04
Filed: 1963-10-21
Abstract: A cellulosic ion-exchange material is made by a process comprising the steps of (a) treating a cellulosic material with acid to remove the amorphous regions of the cellulose, (b) mercerizing the resulting acid-degraded product, (c) cross-linking the mercerized product and (d) reacting the cross-linked mercerized product with a reagent to form the desired cellulosic ion-exchange material.  Cotton linkers is the preferred starting material.  Preferably, step (a) is effected by treating the cellulosic material with an acid at a concentration up to 6 N at from 40 to 120 DEG  C. (e.g. N.HCl may be used), step (b) by treating the acid-degraded product with an alkali solution of 17 to 46% w./w. concentration especially 18% caustic soda, and step (c) by treating the mercerized product with epichlorhydrin, optionally in water at a concentration of at least 3% by weight. The cross-linked product may be treated with an alkali solution of 3% to 46% w./w. concentration prior to step (d), which may be effected in an aqueous medium or in an organic medium, suitably isopropyl alcohol or benzene.  The reagent used in step (d) may be 1,3-propanesultone, sodium chloracetate, or chloroethyl diethyl ammonium hydrochloride, used to prepare respectively sulphpropoxycellulose, carboxymethyl cellulose and diethylamino ethyl cellulose.  Step (d) may be effected to an extent sufficient to provide a cellulosic ion-exchange material having an ion-exchange capacity of up to or greater than 2 m. eq./dry gram. There may also be introduced into the matrix of the cellulosic material non-ionic substituent groups capable of inducing selective interaction effects in a reversible exchange of ions in aqueous solution between the thus modified cellulose matrix and an exchanging ion.  Specified non-ionic substituent groups include benzyl, methyl, acetate and stearate groups.  Benzyl groups may be introduced by reacting benzyl chloride with the cellulosic ion-exchange material from step (d), or with the mercerized product from step (b).  Other reactants which may be used include sodium benzyl chloride p-sulphamate, sodium benzyl chloride p-carboxylate or p-trimethyl ammonium benzylchloride chloride. Examples illustrate the production of sulphpropoxycellulose, carboxymethyl cellulose, diethylaminoethyl cellulose, sulphpropoxybenzyl cellulose, carboxymethylbenzyl cellulose, diethylaminoethylbenzyl cellulose, quaternary ammonium benzyl cellulose, and quaternary ammonium cellulose.

A method of providing protection for the surface of a casting comprises first spraying a self-fluxing hard-surfacing alloy upon a former to provide a coherent layer and subsequently casting a metal in contact with the layer so that the temperature throughout the layer rises beyond the solidus temperature of the alloy which fuses to form a dense protective coating metallurgically bonded to the casting. The term " self-fluxing " means that the alloy itself contains elements such as boron and silicon which react with adjacent oxides of the cast metal or the cast metal itself to clean up the surface and permit bonding. In the manufacture of a gun-metal storm valve the ends 6 of a sand core 5 are flame-sprayed with a hard-surfacing alloy containing cobalt, nickel, chromium, boron and silicon, to provide after casting a member, Fig. 9, with hard-surfaced pivot surfaces 9, the gun-metal being poured at approximately 1410‹ C. In a modification, the alloy layer is sprayed on a metal former from which it is detached by splitting and backed up with sand for casting. The casting and melting may be performed in a vacuum or inert atmosphere. The cast metal may be titanium, aluminium and aluminium alloys, where considerable super-heating is required, cast iron, mild steel, and bronze.
