  • [专利] Improved timber frame insulating elements
    (GB2542110) An insulating timber frame building element (10) defining at last one cavity (22) and comprises a polymeric foam (42) within the at least one cavity (22), wherein the polymeric foam (42) is formed within the at least one cavity (22) from a polymeric foam precursor (38). The polymeric foam precursor (38) is expanded within the at least one cavity (22) by a blowing agent. The blowing agent substantially comprises pentane (n-pentane, iso-pentane, cyclo-pentane or mixtures thereof). Further blowing agents which may be used in addition to pentane are methyl formate, formic acid, hexane, heptane, water, CO2, sodium bicarbonate, titanium hydride, light alcohols, ketones and ethers. The polymer may be selected from addition polymers (e.g. polystyrene) or condensation polymers (e.g. polyurethane or polyisocyanate). Some aspects of the invention relate to the field of fabricating elements for building thermally insulated homes.
  • [专利] Microalgae cultivation process and equipment
    (GB2539936) Microalgae cultivation equipment in which a raceway 1 (also known as an open pond or open photobioreactor) comprises multiple upright photobioreactors 2 (also known as closed photobioreactors, air lifts or bubble columns) and a means for inducing flow through the raceway 16 (such as paddle wheels, impellers or water jets). The lowermost end of the photobioreactor columns are immersed inside the liquid growth medium in the raceway component and are fed with liquid growth medium by a circulation promoting facility 3 circulating the liquid growth medium from the raceway through the photobioreactor columns to become discharged back into the raceway. Gas inlets provide CO2 containing gas bubbles passing upwards in each of the photobioreactor columns 14. This arrangement increases the total surface area of liquid medium exposed to light and allows greater control of CO2 levels in the growth medium.

The lower section may be eccentrically arranged with respect to the longitudinal axis of the open upper section.
  • [专利] Composite materials from layered silicate clay and method of making grinding wheels using the same
    (IN2015KO00742) The present invention relates to a method of preparing nanocomposite grinding wheel using layered silicate-epoxy nanocomposite material. More specifically the montmorillonite-type-clay is modified into organo clay which is cured in presence of the epoxy resin facilitating for a crosslinking reaction between the organo clay and the epoxy resin at lower temperatures resulting in a nanocomposite with strong adhesion which is dispersed in a polymer tube comprising of styrene monomer. Further benzoyl peroxide is added to the mixture and is heated followed by crushing. The crushed polymerized material is heated in an vacuum oven for a certain period of time.
