Title: Improvements in or relating to wringing machines, mangles, calendering presses and the like
Inventor: SHAW JOHN
IPC: D06F45/00
Filed: 1947-10-27
Abstract: 647,695. Wringers. PARNALL (YATE), Ltd. Oct. 27, 1947, No. 27907/48. Divided out of 647,649. [Class 138 (ii)] A wringing machine has a fixed frame member which provides the main support for the rollers, in which one roller is rotatably mounted on a fixed bearing and a second roller is rotatably mounted upon a bearing carried by an arm which projects from the frame member into the second roller, the arm being fulcrumed on the frame and engaged by a rigid link which is pivoted on a spring controlled adjustable member, consisting of a carrier for a helical spring through which said arm passes, the link being disposed between the arm and the frame member and having a longitudinal dimension greater than the distance between the arm and the frame, the arrangement being such that on compression of the spring, the link is constrained to tilt the arm about its fulcrum, so urging the second roller into engagement with the first roller. A lower roller 2 is rotatably mounted in a fixed bearing 6, in a frame 1, and is drivable by a handle 10. An upper roller 3 is rotatably mounted on the outer end of a rigid arm 14 which is recessed to receive a bearing surface 15 on the frame 1. The other end of the arm 14 is screwed to receive a hand wheel 16 which abuts a saddle-shaped sleeve 17 slidable on the arm 14 and engaging a helical spring 18 surrounding the arm and carried in a rightangled bracket 21 formed with side webs. The saddle 17 is shaped to clear a stop pin 19 on the arm, and an abutment 20 integral with the saddle is engageable with the pin at the limit of movement of the saddle, when pressure on the spring 18 is released. The bracket 21 rests on a roller 22 seated in a recess in a projection 23 formed on the frame 1. The roller 22 may be dispensed with and the projection 23 rounded at its top to provide friction-free movement of the bracket 21. A link 24 having rounded ends is pivoted between ears projecting from the bracket 21. One end of the link engages a recess in the frame 1 while the other end engages the lower surface of the arm 14 at a point between the pin 19 and the end of the arm. Compression of the spring 18 causes the bracket 21 to slide over the roller 22 and thus by carrying the link 24 with it, raises the arm 14 within the frame 1. The outer end of the arm is thus depressed to urge the roller 3 into pressure engagement with the roller 2. Specification 634,731 is referred to.

IPC: C09D11/10
Filed: 1948-10-30
Abstract: A moisture setting printing ink comprises a dispersal of a pigment in solution in a water-miscible glycol of a brittle, non-sticky alkyd resin, readily soluble in the glycol but precipitated therefrom by addition of water, the resin being formed from dicarboxylic acids comprising a major proportion of phthalic acid and/or a saturated aliphatic acid of 4-6 carbon atoms in the molecule together with a minor proportion of an a ,b  unsaturated dicarboxylic acid of not more than 6 carbon atoms in molecule, and one or more polyhydric alcohols such as ethylene glycol, glycerol, pentaerythrytol and trimethylol propane.  Not more than 60 per cent by weight of the total alcohols should be represented by dihydric alcohols.  The a ,b unsaturated acids specified are maleic, fumaric, itaconic, mesaconic and citraconic acids.  The minor proportion of a ,b  unsaturated acid may also contain an a ,w-dicarboxylic acid having not less than 5 carbons in the chain, e.g. pimelic, suberic, azelaic or sebacic acid. The proportion by weight of the total reactants of the a ,b  and the a ,w dicarboxylic acids are preferably 5-15 per cent and 2-10 per cent respectively.  The resins may be made by heating the reactants, e.g. between 160 DEG  and 240 DEG  C., until a sample withdrawn from the reaction mixture sets on cooling to form a brittle, non-sticky resin.  The reaction may be conducted in an inert solvent.  In one method of making the inks, the resin is dissolved in the solvent such as diethylene-, dipropylene- or triethylene glycol and the resulting varnish is converted into an ink by grinding with pigments; in another method the varnish is cooked by heating, e.g. to between 160 DEG  and 220 DEG  C. for 1/2 to 4 hours.  In examples: (1) a resin, made by heating glycerol, ethylene glycol, phthalic anhydride and maleic anhydride is dissolved in diethylene glycol and the resulting varnish is converted into an ink by mixing and grinding with coprecipitated alumina hydrate and blanc fixe. phosphomolybdic lake of Victoria blue and diethylene glycol; (2) a resin made from glycerol, diethylene glycol, pentaerythritol, phthalic anhydride; fumaric acid and sebacic is used to make an ink as in (1); (3) the resin of example (2) is dissolved in glycerol and diethyleneglycol and heated for 3 hours at 180 DEG  C. and the resulting varnish is used for making an ink (4) by mixing and grinding with diethylene glycol, coprecipitated alumina hydrate and blanc fixe and phosphomolybdic lake of Victoria blue; (5) the resin made by heating phthalic anhydride, ethylene glycol and pentaerythritol is converted into an ink similar to that of (4) for purpose of comparison.
