Title: Improvements in or relating to modified fatty esters and derivatives thereof
Inventor: WAKEFORD LESLIE ERNEST
IPC: C09D125/14
Filed: 1950-08-11
Abstract: Modified fatty esters and derivatives thereof are prepared by heating aromatic vinyl hydrocarbons, e.g. styrene, with unpolymerized, unsaturated fatty esters and/or their fatty acids, at a temperature above the boiling point of the system at atmospheric pressure, in a closed vessel under super-atmospheric pressure sufficient to maintain the reaction system in the liquid state.  The reaction temperature may lie between 250 and 300 DEG C. and the pressure may be autogenous.  The fatty esters may be naturally occurring fatty oils, e.g. linseed, oiticica, and raw tung oils, their partial esters, e.g. monoglycerides, which may be modified with mono or polycarboxylic acids to give oil modified alkyds, or fatty acids or isomerised acids therefrom e.g. dehydrated castor and linseed oil fatty acids.  If a major proportion of non-conjugated fatty oil or acid is used a minor proportion of conjugated fatty oil or acid may be added, and a natural or synthetic resin or partially polymerized fatty ester may be included at any stage.  The reaction may be carried out in bulk or in an inert solvent such as white spirit or dipentene, and the reactants may be added portionwise, or an excess of volatile ingredients added and removed by distillation.  The modified fatty acids may be used to esterify alcohols particularly polyhydric alcohols such as glycerine, or reacted with polybasic acids and polyhydric alcohols with or without unmodified fatty acids to give oil modified alkyd resins or to prepare partial esters with polyhydric alcohols to form, for example, mono-glycerides which may be used to form modified alkyd resins.  The alkali metal, ammonium and organic base soaps of the modified fatty acids may be used as emulsifying agents and detergents, the zinc, calcium, magnesium and aluminium soaps as dispersing agents and water-repellent materials and the cobalt, manganese and lead soaps as paint driers.  The esters or alkyd resins may be used in air-drying coating compositions and as plasticizers. Specifications 573,809, 573,835, 580,912, 609,750, 611,109, 616,044, 622,948, 622,949, 630,022, and 640,836 are referred to.

Title: Improvements in sheet-feeding devices for coating and like machines
IPC: B41F21/00
Filed: 1935-07-16
Abstract: <PICT:0448818/III/1> <PICT:0448818/III/2> In a machine for coating flexible sheets with stripes of colour, gum, &c., the sheets are fed from a pile and are carried through coating rollers, which may act on one or both sides of the sheet, by conveying means which do not comprise grippers and which are arranged to prevent angular displacement of the sheets during their travel.  The sheets are propelled through the coating rollers 34, 35 by the friction of the rollers which are preferably rubber covered.  The sheets are fed from a pile 11 by means of reciprocating pneumatic separators 16, and the separation is assisted by a work-holder 14, air blast devices 15, and adjustably mounted rollers 18 prevent buckling of the top sheet.  The sheets are carried to the coating rollers 34, 35 by means of a conveyer 20 of a length less than that of the sheet, the conveyer being formed of belts 30 passing over a roller 27 and over pulleys 28. A pair of rollers 21 carried by adjustable arms 23 coact with the roller 27 to control the direction of travel of the sheets, and these may be set to cause the stripes to be arranged parallel to or at an angle to the edges of the sheets.  The undersides of the sheets are coated or printed by rollers 34 receiving gum, or colour from a fountain roller 32 fitted with a regulating roller 33.  The upper side of the sheet may be coated by the roller 35 receiving its supply from the roller 34 at the intervals between the passage of successive sheets.  Distributing rollers 36 which may be oscillated are fitted to the roller 35.  In a modification in which only one side of the sheet is coated, a sheet is fed once for each revolution of the roller 35, and receives its coating from the major portion of the roller 35.  A stripper 26 directs the coated sheet to a conveyer 40 which directs it through a drying-device comprising adjustably mounted heaters 41, and adjustable heat retainers and deflectors 42 arranged at the sides and extending above the conveyer belts 40.
