Means for providing flowable colourant in a coating composition

Abstract: A more easily useable means for providing dispersed flowable colorant in a coating composition contained in a liddable container which means may have none of several alternative heights. The means comprises dispenser 18 at which a dose of flowable colorant 1 can be introduced into a container 20 which contains a base paint 2. A shaker 24 is provided and is laterally spaced from the dispenser 18. A surface 14 extends from the dispenser 18 to the shaker 24 along which the container can be moved making transfer to the mixing station particularly easy. The means can also include labelling and lidding stations 22, 23 between the dispenser and shaker 18, 24. FIG. 1 .

Composite particle dispersions

Abstract: A process for the preparation of composite particle dispersions is disclosed. The composite particles have a core particle 1 surrounded by a second material 2. Normally a core shell particle will be formed and the second material which forms the shell will be a polymer material. The composite particles are formed by mixing a dispersion of polymer particles with pre-formed core material particles. The polymer particles are stabilised relative to one another, and the core material particles are destabilised in the dispersion so that they are able to make contact with the surfaces of the polymer particles. The process takes place at a temperature above the operative glass transition temperature of the polymer, and in the process the polymer spreads over the surface of the core particle so that the core particle is encapsulated. The process will proceed, and composite particles will be formed, when the interfacial energies of the three interfaces (core/polymer: core/liquid: polymer/liquid) and the relative volumes of the core particles and polymer particles are related to one another in accordance with an equation which is set out in the specification.

Sprout development and subsequent plant growth

Abstract: During storage sprout growth was linearly related to the amount of available tuber substrate. Plants grown in nutrient solution were also highly dependent on the reserves of the parent tuber until a relatively late stage of development. Light intensity and daylength only slightly influenced sprout growth: temperature and variety were of considerable importance. Increase in sprout size at the time of planting caused earlier emergence and tuber initiation but the relative rate of plant growth was reduced. The principal weather factors which modified tuber initiation and growth were temperature and radiation: daylength was relatively unimportant. The different optimum temperatures during development suggest a technique for obtaining higher tuber yields.
