Abstract: A double-glazing assembly suitable for horticultural and agricultural growing houses comprises two flexible light-transmitting thermoplastics film, especially polyethylene terephthalate films, separated by a spacing framework. Means are provided to evacuate the enclosure between the sheets during the day-time thereby improving the light transmission of the assembly. The assembly is also preferably provided with means for inflation to optimise the conservation of thermal energy during the night-time.

Abstract: A laminate comprising a layer of a synthetic linear polyester, a plasticizer-free primer coating applied to at least one surface of the polyester layer and comprising a cross-linked composition comprising a polymer of at least one monomer selected from the esters of acrylic acid and methacrylic acid, and optionally acrylic and/or methacrylic acid, and at least one layer made from a plasticized vinyl chloride polymer composition which is bonded to the linear polyester layer through the intermediary of the primer coating. The primer coating preferably includes the condensation product of an amine with formaldehye to effect cross-linking.

Abstract: water-impregnated textiles, especially of cellulose or wool, or mixtures of cellulose and wool with synthetic fibers and synthetic textiles, such as nylon and acrylics, particularly as assembled garments, are wet-transfer printed with a transferable printing design comprising a dyestuff which is reactive with the textile by heating the impregnated textile in contact with the design while maintained in a water-impervious enclosure comprising a polyester film or sheet, such as poly(ethylene terephthalate). The design is preferably applied to the polyester film or sheet which may be pretreated to facilitate coating with the transferable design. The pretreatment may comprise a wettable resin coating such as a cross-linked copolymer of acrylic acid, methacrylic acid or their glycidyl or lower alkyl esters.
