Abstract: 1479415 Seaming non-metallic sheet material CARDER INDUSTRIES Inc 25 Nov 1975 [2 Dec 1974] 48456/75 Heading B5K Two sections 11, 12 of fabric, e.g. carpet, are seamed together by coating or impregnating a flexible permeable seaming tape 10 with a first liquid adhesive; allowing the adhesive to dry in the tape; placing a strip of the tape on a surface to be covered by the sections 11, 12; applying to the undersides of two sections 11, 12, adjacent the edges to be seamed, a second liquid adhesive containing a solvent for the first adhesive; and urging the undersides of the sections 11, 12, while the adhesive thereon is still moist, against the strip of tape, whereby the solvent in the second adhesive penetrates and remoistens the first adhesive to form a bond when the adhesive dries. Preferably, the tape 10 comprises non-woven polyester fibres and is impregnated, during manufacture, on one side thereof, with an adhesive comprising a neoprene base and a methyl-ethyl-ketone solvent. During installation of carpet sections 11, 12, a strip of the tape 10 is placed adhesive-side-up on the floor so that its centre line registers with the intended seam line S. The strip ends may be releasably secured during seaming. The sections 11, 12 are positioned so that their edges to be seamed abut the line S and these edges may be stretched in the direction of the line S. The sections 11, 12 are temporarily tacked along lines spaced inwardly from their edges which are then bent back about the tack lines. The same liquid adhesive, which was applied to the tape 10 during its manufacture, is applied to the exposed underside areas 14, 15 of the sections 11, 12. The edges of the sections 11, 12 are urged into abutment so that the solvent of the adhesive on the areas 14, 15 dissolves partly the dry adhesive in the tape 10. After seaming, the temporary tacks are removed. In a modification, Fig. 2, a seaming tape 20 comprises a non-woven tape 21 saturated on both sides with an adhesive. Whilst the adhesive is still tacky, the tape 21 is adhered to a wider supporting tape 22 which prevents lateral stretching of the tape 21.

Title: Perfluoro polycyclic compounds for use as synthetic blood and perfusion media
IPC: C09K23/42
Filed: 1975-12-09
Abstract: An emulsion for flushing organs to be transplanted is described, which contains perfluorinated hydrocarbons, dispersed in water, and additionally a non-toxic emulsifier. It must contain a total of more than 40% by volume of water. The perfluorinated materials are the perfluorination products of either   (1) polycyclic hydrocarbons having at least two bridge head carbon atoms linked to each other via a bridge containing at least one carbon atom and which are not adamantane, or (2) methyladamantane, ethyladamantane, ethylmethyladamantane, ethyldimethyladamantane or triethyladamantane.   These perfluorination products have an excellent dissolving capacity for oxygen and carbon dioxide and they form highly stable emulsions with good resistance to the high shearing forces which are applied to the emulsions when they flow through apparatuses which load the emulsions with the necessary oxygen, which they transport to the organs to be transplanted. The emulsions permit organs which are to be transplanted to be stored for a long time, and when, on the other hand, part of the emulsions reaches the human body as the organs through which the emulsions flow are transplanted, they are not toxic there and are excreted again after some time by way of respiration and via the skin.
