Title: Polymeric pigment dispersants
IPC: C09C3/10
Filed: 1971-05-06
Abstract: 1350284 Polymeric dispersants for organic pigments IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA & NEW ZEALAND Ltd 6 May 1971 [14 May 1970] 13473/71 Heading C3P A polymeric dispersant for dispersing an organic pigment in an organic liquid medium, comprises a backbone chain having incorporated in it or dependent from it one or more solubilizing groups such as a C 8 -C 20  alkyl group, and one or more ionic groups, which are groups which are already charged, or are capable of forming an ion, said ionic group being in the form of a salt with a salt-forming component which is a substance capable of forming a salt with the ionic group, and having an affinity for the surface of the organic pigment particles; the polymer must contain 99-50 mol per cent of the solubilizing group-containing units, and 1-50 mol per cent of the ionic group containing units. The solubilizing group is one which is solvatable by the organic liquid, such as 2-ethyl hexyl, dodecyl, stearyl or phenyl for saturated hydrocarbons, and polyethers for alcoholic solvents. Suitable ionic groups (as defined) are carboxylic acid, sulphonic acid or phosphoric acid groups or their salts, primary-, seoondary- and tertiary amino groups, quaternary ammonium groups, phosphonium and sulphonium groups. The salt-forming components vary widely, and may be for example a pigment modified with an ionic compound which contains any of the ionic groups listed above, an ionic intermediate in the manufacture of the pigment or, in the case of "rosinated pigments", substances such as dehydroabietic acid, abietic acid, cholic acid, desoxycholic acid, cholanic acid and 12-keto cholanic acid. Also, for toners and lake pigments, suitable salt forming components are naphthalene sulphonic acids, anthracene and phenanthrene sulphonic acids, benzene sulphonic acids and formaldehyde condensates of naphthalene-2-sulphonic acid. Preferred polymers are addition polymers. In the examples, copolymers of dimethylamino ethyl methacrylate and 2-ethyl hexyl aorylate in which the amino groups are quaternized with benzyl chloride or, in Example 2 only, dimethyl sulphate, a copolymer of 2-methyl thio acrylate, 2-ethylhexylacrylate and methacrylic acid, reacted with dimethyl sulphate, and a copolymer of allyltriphenyl phosphonium bromide and 2-ethyl hexyl acrylate, are reacted with salt forming components which are selected from rosin, cholic acid, formaldehyde condensation product of naphthalene sulphonic acid, polymerized rosin, hydrogenated polymerized rosin, sulphonated copper phthalocyanine paste, the sodium salt of the coupling product of the diazo salt of 2-chloro-4-aminotoluene-5 sulphonic acid and 2-hydroxy naphthalene-3- carboxylic acid, the coupling product of the diazo salt of 3,3<SP>1</SP>-dichloro-benzidine with sodium acetoaoetanilide para sulphonate, and an ionic pigment of C.I. number 23900.

The apparatus for carrying out the process comprises (Fig. 1) a container for the coating agent, a container 2 for the additive composition for maintaining constant viscosity and an automatically controlled valve 3.  The object to be coated 5 is introduced into the spray chamber 4 by a transport device 9 such as a chain attached to a roller 8 or other sliding device moving on a rail 6.  Spray nozzles 7 coat the object which is then transported in the direction of the arrow a into the chamber 10 when excess coating material drips off on to the draining surface 23 and flows back into the container 1.  The ratio of binder to solvent to water is maintained constant by measuring the viscosity or concentration of the composition.  Other methods are also listed.  Arrangements are described and illustrated whereby marring of the coated article in the drying chamber 10 by condensed droplets of the coating mixture is prevented.
Patent GB-971467-A (GB)
Title: A shift mechanism for power-driven typewriters
IPC: B41J23/12
Filed: 1961-04-14
Abstract: 971,467. Typewriters. OLYMPIA WERKE A.G. April 14, 1961 [April 16, 1960], No. 13513/61. Heading B6F. A case shift mechanism for either the type segment or the carriage of a power-driven typewriter comprises a cam rotated through a certain angle when the shift key is depressed and acting on a follower 20 on the segment &c., the operative surface of the cam having substantially the form of a quarter - of a circle disposed eccentrically to a shaft 21 on which the cam is fixed. The cam comprises a slot 23a in a plate 25 adjustably mounted by means of an eccentric screw 24 on a carrier 23 fixed to the shaft 21, the slot having extensions beyond its operative part which are concentric with the shaft. The follower roller 20 is carried by a bracket 17 adjustably attached to the segment 3 by an eccentric screw 18. Fixed to the shaft 21 is a lever 22, one end 22a of which is attached to a spring 26 which swings over a dead-centre position as the cam 23a moves from one extreme position to the other. The other end 22b of the lever 22 is pivoted to a link 27 which at its far end is pivoted by a pin 28 to a toothed disc 29 adjacent to the driving knife-shaft 30 of the machine. The teeth on the disc 29 adjacent to and diametrically opposite the pin 28 are omitted. A spring-controlled shift key 35 has a forked inner end 32a, 32b with bentover lips 32d, 32c. In non-shift position, the lip 32c engages the pin 28 and prevents movement of the parts 27, 22, 21, 23 by the spring 26. Depression of the key 35 causes the release of the pin 28 thus allowing the spring 26 to effect an initial movement of the parts mentioned, no movement of the segment occurring, however, due to the concentric end of the slot 23a. After the initial movement, the teeth on the disc 29 engage the toothed shaft 30 and a powershift movement takes place. When the disc 29 has rotated nearly half a revolution, its other blank part is adjacent to the shaft 30 and the drive is disengaged. The spring 26 however causes further movement until the pin 28 abuts against the lip 32d which is positioned in its path when the key 35 is depressed. Upon release of the key, the parts are again freed to make an initial movement under the action of the spring 26 so as to couple the disc 29 to the shaft 30 and effect a shift back to the non-shift position. If the segment 3 is to be held in the shift position for a substantial time, a lock key 37 is depressed to bring a hook 36b thereon below a holding member 39. To each end of the type-segment 3 is fixed a horizontal plate 6 carrying a bolt 7. Locknuts 8, 9 on the bolts engage spring-supported washers 10, 11 at the ends of the upward and downward movements respectively of the segment to cushion the movements.
