Abstract: A thermosensitive recording element having improved abrasion resistance, said element comprising (a) a support; (b) a first layer comprising an organic polymeric binder and either a substantially colorless electron donating dye precursor or an electron accepting compound or mixtures thereof; and (c) a second layer comprising an organic polymeric binder compatible with the binder in (b) and either a substantially colorless electron donating dye precursor or an electron accepting compound, wherein both dye precursor and electron accepting compound are present in the element and wherein the first layer is interposed between the support and second layer. These elements have wide application in the printing industry.

Abstract: A thermosensitive recording element comprising a support having a Sheffield smoothness of less than 60, and at least one layer provided thereon wherein said layer comprises an organic polymeric binder, a substantially colorless electron donating dye precursor and an electron accepting compound capable of forming color by reacting with said dye precursor, wherein the binder, the electron accepting compound and the dye precursor have a particle size of less than about 3.mu..

Abstract: An abrasion resistant thermosensitive recording element having high gloss, and improved abrasion resistance and process of preparing said element are described. The element comprises (a) a support, (b) a first layer comprising an organic polymeric binder and a substantially colorless electron donating dye precursor, and (c) a second layer comprising an organic polymeric binder compatible with the binder in (b), an electron accepting compound capable of forming color by reaction with said dye precursor, and a crosslinking agent, wherein the first layer is interposed between the support and the second layer. These elements have wide application in the printing industry.

Abstract: A cushion construction for positioning below a patient suffering from incontinence which is hygenic to use and which does not require permanent modification of a mattress or seat on which it is to be used is formed as a resilient body, particularly a foam block, having an upper surface (1) substantially parallel to its lower surface when the cushion is unstressed with the upper surface (1) being interrupted by a fluid collection and channelling area (3) including an inclined drainage plane extending downwardly into the body of the cushion to a drain hole (2) in an interior region thereof communicating the lowermost region of the inclined drainage plane with the underside of the resilient block. At least those surfaces of the cushion which will be contacted by urine will be covered with fluid impermeable sheet material (4). The cushion has optional urine collection systems either for use with a conventional incontinence pad or comprising a drainage duct (37) to a fluid container (38).

Abstract: An aperture stop assembly is shown which may be utilized within a laser beam optical system whose laser beam has been split into zero, first and second order beams. A lens is provided to focus the split beams upon a focal plane where an aperture stop is mounted having an aperture aligned with the desired first order beams. The reflective surface of the aperture is arranged at an angle to reflect the unwanted zero and second order beams into a series of absorption baffles found within the aperture stop housing or the aperture stop may absorb unwanted beams directly.
