Abstract: A stoving surface-coating composition is made by at least partially neutralizing the addition product of an unsaturated dicarboxylic acid and an unsaturated fatty acid or an ester thereof, with a di- or polyamine, and dissolving or emulsifying the product so formed in an aqueous medium.  Ammonia may be used in place of part of the di- or polyamine, which preferably is a primary amine containing from 1 to 4 carbon atoms in the molecule to each amine group.  Suitable addition products are those of maleic acid with unsaturated fatty acids or esters thereof, or with unsaturated animal and vegetable oils (so-called "maleate oils"), which products may be further modified by partial esterification with an unsaturated alcohol.  Pigments and extenders may be incorporated.  In Examples (1) a linseed/wood oil "maleate oil" is partially esterified with allyl alcohol and mixed with a cobalt naphthenate drier, before dissolving in aqueous ammonia at 60 DEG C.  Ethylene diamine is then added and the mixture diluted with water to produce a suitable concentration for spraying or brushing on to a substrate, followed by drying and storing.  (2) Linseed oil "maleate oil" is mixed with cobalt naphthenate and dissolved at 60 DEG C. in a mixture of aqueous ammonia and diethylene triamine, the resulting solution being applied to a metal article, dried and stoved.

Title: Improvements in and apparatus for the preliminary treatment of tea leaf
IPC: F26B1/00
Filed: 1950-04-03
Abstract: 668,013. Tea manufacture. SAYAMA TEA ESTATES, Ltd., and WORTHINGTON, W. R. April 3, 1950, No. 8252/50. Class 129. In the preliminary treatment of unwitliered tea leaf the leaf is subjected to a plurality of pressure operations between surfaces at least one of which is of resilient material. By thus treating fresh unwithered leaf moisture can subsequently be expressed from it under moderate pressure, withering being dispensed with. Leaf fed at A to an endless belt 1 passes between belts 1 and 10 to be subjected to nips imparted by a plurality of rollers 3, and leaves at B where scrapers 16 are provided, the outer surface of one or both belts being of e.g. rubber. The belt 1 is carried by a drum 2 and by the rollers 3 which are mounted for rotation in circular end plates 4, the belt 10 being mounted on rollers 11, 12, 13. The shaft of the roller 11 is mounted in bearing houses 14 slidable in an outer frame, the shaft of the drum 2 being mounted in spring- loaded bearing houses also slidable in said frame, so that by means of screws 15 or hydraulic plungers the pressure between the belts 1, 10 can be adjusted. The number of times the leaf is nipped by the rollers 3 may be varied by altering the direction of rotation and the speed of revolution of the end plates 4. Semi-circular grooves near the edges of the belts 1, 10 cooperate to form ducts through which moisture expressed from the leaf can escape, alignment and sealing of the edges being effected by V- shaped projections along the edges of the belt 10 engaging corresponding grooves in the belt 1. The belts may be cleaned by water jets 20 and rotary scrubbers 21. In alternative constructions the leaf is either passed several times through a pair of manually operated rollers, one or both having a surface of resilient material, or is passed through a plurality of such pairs.
