Filed: 1971-04-19
Abstract: 1342038 Resin dispersions stabilized by a graft polymer ROHM GmbH 19 April 1971 [26 Feb 1970] 21907/71 Headings C3G and C3P A dispersion of a particulate synthetic resin (R) in an anhydrous organic liquid (L) is stabilized by a graft-copolymer (G) derived from: (a) a base polymer soluble in (L) containing units with side-groups comprising azo or peroxy radicals, and a grafting monomer composition, which is capable of forming a polymer which is insoluble in (L) and compatible with (R); or (b) a base polymer, insoluble in (L) and compatible with (R), containing side-groups comprising azo or peroxy radicals, and a grafting monomer composition, which is capable of forming a polymer which is soluble in (L); (G) being prepared by reacting the grafting monomer composition with the base polymer at a temperature at which the azo or peroxy groups decompose to form free radicals. Two components are said to be " compatible " if they associate and form a common phase; this generally occurs if they are each soluble or insoluble in the same solvents. The dispersion of resin (R) may be formed by radical-polymerizing a monomer composition in the presence of graft polymer (G), liquid (L) being added before, during or after polymerization. Or a solution of (R) in an auxiliary liquid (A) may be prepared and combined with a solution of (G) in a liquid which may optionally be (A), followed by the addition of liquid (L). Or a solution of (R) in (A) may be combined with a solution of (G) in (L), forming the dispersion of (R); (A) may then be removed if desired. Resin (R) may comprise a polymer of C 1-4  alkyl ester(s) of acrylic or methacrylic acid, or of acrylonitrile or methacrylonitrile, and optionally other monomer(s). Liquid (L) may comprise aliphatic hydrocarbons of b.p. 60-200‹ C., e.g. petroleum distillate, or chlorohydrocarbons or alcohols. The base polymer units and the grafting monomer composition may comprise a C 6-18  alkyl ester of an α,#- unsaturated carboxylic acid, e.g. acrylic, methacrylic, maleic, fumaric, or itaconic acid; units of styrene, isobutylene, or vinyl esters of higher carboxylic acids; C 1-4  alkyl esters of acrylic or methacrylic acids; styrene or homologues; acrylonitrile or methacrylonitrile; vinyl esters of lower carboxylic acids, e.g. acetic or propionic; defines; e.g. ethene, propene, butene or butadiene; vinyl chloride; or vinylidene chloride. The base polymer units may also comprise di-(tbutylperoxy)-fumarate, -crotonate, or -methacrylate, or or or dicrotonyl peroxide, diethyl difumaryl peroxide, azobisisobutyric acid di-(vinyloxyethyl)ester, azobis-2,4-dimethyl-pentenic(2) acid dinitrile, or  or  or the mono- or di-amide or -hydrazide of azobisisobutyric acid; or the units may have sidegroups comprising azo or peroxy radicals, these side-groups connecting two macromolecular chains of the base polymer. Use.-Coating, binding, film-forming, fibrousweb-forming.

Title: Improvements in pile delivery mechanism for printing and like machines
IPC: B65H31/18
Filed: 1920-07-26
Abstract: 170,671. Anglo-American Inventions Syndicate, Ltd., (Harris Automatic Press Co.). July 26, 1920. Delivery apparatus.-Table lowering mechanism of sheet-delivery apparatus for printing &c. machines is normally held out of action by a reciprocating mechanism comprising a trip latch when the same is actuated in full stroke, and is brought into operation when the stroke of the reciprocating mechanism is restricted by the increasing height of the pile of sheets on the table. The pile table 21 is supported by chains 24, 25, passing over idler wheels 26, 27, and then wound round sprocket wheels 28, 29, the latter being rigid on shafts 30, 31, with worm gears 35, 36, which engage with worms 33, 34, on a shaft 32. The shaft 32 is fitted with a ratchet wheel 49 adapted to be rotated step by step in each cycle of operation of the delivery chains 11, 14, by means of the cam 41 engaging a roller 42 on a pivoted arm 43 connected by links 44, 45, and 46 to one end of a rock-lever 47 loose on the shaft 32. A pawl 48 pivoted at the other end of the rocklever 47 is normally held out of engagement with the ratchet 49 by means of a notch 51 on a lug 52 on the underside of an oscillating guard 53 loosely pivoted on the shaft 32 and connected by a rod 56, bell-crank 57, and rod 59 to a pivoted lever 60 carrying a detector arm 62 located immediately above the pile 22. If the height of the pile is such that the rocking detector 62 does not contact therewith, the guard 53 rises and falls with the rocking-lever 47, and the pawl 48 is held out of engagment with the ratchet, the table-lowering mechanism being thus inoperative. When the pile has increased to such a height that the detector contacts therewith, the downward stroke of the guard 53 is restricted so that the pawl 48 leaves the notch 51 and is forced by the spring 50 into engagement with the ratchet, whereby the pawl on its next upward stroke beccmes operative for lowering the table. On the next downward stroke of the pawl, an incline on the rear end 54 thereof engages a pin 55 for the purpose of resetting the pawl against the notch 51.
