Title: Esterification of synthetic resinous polyhydric alcohols
IPC: C08G59/16
Filed: 1947-12-13
Abstract: Esters of unsaturated fatty acids derived from vegetable and fish oils are obtained by heating the fatty acids with the complex resinous polyhydric alcohols described in Specifications 675,168, 675,169, 675,170 and 675,171 in such proportions that at least 10 per cent and not more than 75 per cent of the free hydroxyl groups of the alcohols are esterified.  Unsaturated fatty acids specified are those derived from fish oils, e.g. clupanodonic acid, cotton seed oil, linseed oil, chinawood oil, oiticica oil, soy bean oil, corn oil. The resinous polyhydric alcohols are obtained by heating dihydric phenols with epichlorhydrins or polyepoxides.  The esters dissolved in solvents are used as varnishes and adhesives.  Examples (1)-(9) illustrate the production of the resinous polyhydric alcohols and (10)-(21) the production of the esters.  The resins are formed (1) by dissolving 21 mols. bis phenol and 6 mols. phenol in water containing 24 mols. NaOH and reacting the mixture with 24 mols. epichlorhydrin at 55 DEG  C. for 40 minutes, whereupon a further equivalent of 6 mols. NaOH are added and the mixture heated at 93 DEG  C. for 1 hour, 45 minutes.  The upper water layer is removed by decantation and the resinous layer washed free from alkali and dried.  Employing similar procedures resins are obtained from mixtures containing the reactants in the proportions (2) 40 mols. bis phenol, 31 mols. epichlorhydrin and 18 mols. glycerol monochlorhydrin; (3) 18.1 mols. bis phenol, 3.8 mols. phenol and 20 mols. epichlorhydrin, 20 mols. NaOH being present initially and 5 mols. more being added during the reaction; (4) 24 mols. bis phenol, 12 mols. phenol and 30 mols. epichlorhydrin; (5) 0.86 mols. bis phenol, 0.28 mols. phenol and 1 mol. epichlorhydrin; (6) 2.5 mols. bis phenol, 2.5 mols. p,p1-dihydroxy-diphenyl sulphone and 6 mols. epichlorhydrin; (7) 3 mols. resorcinol, and 3.5 mols. epichlorhydrin; (8) 37.5 mols. bis phenol and 52.5 mols. epichlorhydrin; (9) 765 parts of the product of example (8) were further reacted with 102.5 parts bis phenol.  In the examples describing the esterification of the resins the proportions and fatty acids employed are: (10)-(12) 500 parts of the resin of example (1) and 220, 335 and 125 parts dehydrated castor oils acids; (13) 500 parts of the resin of example (2) and 335 parts linseed oil acids; (14) 250 parts of the resin of example (1) and 62.5 oiticica oil acids; (15) 500 parts of the resin of example (3) and 335 parts castor oils acids; (16) 200 parts of the resin of example (4) and 100 parts soya bean fatty acids; (17) 200 parts of the product of example (8) and 100 parts dehydrated castor oil acids.  In example (22) a mixture of 39 parts diglycid ether and 45.6 parts of bis phenol were heated at 190-215 DEG  C. for 1 hour to give a product softening at 88 DEG  C.  This product was mixed with 25 parts linseed oil acids and the mixture heated to 225 DEG  C. until the acid value was 5. The product dissolved in solvents was used as a lacquer.

Title: Improvements in floor polishers with rotatable polishing members
IPC: A47L11/08
Filed: 1947-12-16
Abstract: 636,285. Floor-polishing machines. HELLER, R. J. Dec. 16, 1947, No. 33121. Convention date, Nov. 21, 1946. [Class 138 (i)] A hand-operated floor polisher comprises a main polisher plate 1 on the underside of which rotatable brushes 7 are mounted, the brushes including brush-supporting plates 6, each adapted to rotate about its axis and which plates are mounted to pivot about a horizontal axis and are set at an inclination to the polish plate transversely of the polishing direction by spring means in such a manner that the pressure of each brush on the floor is greater on one side than on the other, so that the brushes are rotated during the polishing movement. As shown in Fig. 6, the brush plate 6 is rotatable about a spindle 9 fixed to a cross-member 12 pivoted on a spindle 13 supported in the main polisher plate 1. One side of the cross-member is urged downwardly by a spring 16 disposed between the polisher plate and the crossmember while the other side of the plate is limited in its upward movement by a projection 18 on the cross-member. The strength of the spring is so arranged that the weight of the main polisher plate causes the brush to lie flat on the floor. Owing to the greater pressure on one side of the brush the brush will rotate when the polisher is moved in the axial direction of the spindle 13. Two or more brushes may be mounted on the underside of the main polisher plate. When several brushes are employed one set is arranged to rotate in the opposite direction to the other set during polishing, so that the polisher does not tend to gyrate, which would cause it to swing arcuately when moved linearly. A felt polishing pad 19, Fig. 5, provided with an upstanding tube 20 can be fitted to the bottom of a brush by sliding the tube 20 over a downwardly-projecting portion of the hub 8 of the brush plate 6.
