  • Patent number: 4797310
    Abstract: An article suitable for delivering or absorbing liquid includes a substrate carrying a pressure-sensitive porous polymeric material which is capable of retaining at least 10 times its own weight of water or corresponding amounts of other liquids. The porous polymeric material is advantageously a crosslinked homogeneous block material having a dry density of less than 0.1 g/cc and a pore volume of more than 9 cc/g, and may be produced by polymerization of a high internal phase emulsion. In the article of the invention, the polymer may either be dry or contain an included liquid; the dry form is highly absorbent and is useful for mopping up slippages, while the liquid-containing form is useful for delivering treatment liquids, for example, cleaning compositions, to surfaces. The article may take the form of a single- or multi-compartment sachet of paper or nonwoven fabric containing the porous polymeric material.

  • Patent number: 4789582
    Abstract: A heat-retention device for windows, doors or the like is proposed, in the form of a curtain (10) or roller shade, which has a plastic foil as a carrier, to which at least one vapor-deposited or atomized metal coating having a high reflective capacity in the long-wave heat radiation range is applied. The plastic foil is subdivided at least in some areas, for instance by perforation (11) or by the joining together of narrow strips (15, 16), in order to alter its mechanical properties with a view to reducing its elasticity. The result is a structure which is substantially better and esthetically more pleasing when used in the form of curtains or roller shades.

  • Patent number: 4778706
    Abstract: A composite laminated, non-distortable needlepoint canvas material comprised of a primary layer of non-elastic, open-mesh woven fabric having a uniform weave pattern of mesh apertures and a relatively thin secondary mesh-stabilizing layer of sheer non-elastic fabric material. The threads of the open-mesh primary layer are bonded to the sheer secondary layer by an interposed adhesive layer with the apertures of the primary layer being functionally free of adhesive and the threads of the primary layer are not susceptible to raveling at the edges of the composite needlepoint material. The sheer fabric secondary layer may be a non-woven, semi-transparent, random spun synthetic fiber material or a sheer closely woven fabric material. The secondary layer is bonded to the primary layer by a liquid adhesive applied to one face of the primary layer before it is compressively interfaced with the secondary layer (with the application of heat) or the secondary layer may itself have adhesive properties.
