    摘要： A hollow pipette member open at its opposite ends contains a plug of porous, hydrophobic material force fitted between its ends to define a liquid sample chamber between the plug and one end of the tube. At least a major portion of the pores of the plug material are impregnated with particles of a liquid scavenging material which are of smaller size than the pores so as to allow gas to be drawn through the plug. The liquid sample chamber is of predetermined volume greater than the volume of liquid drawn by a suitable suction device attached to the opposite end of the tube, so that an air gap will remain between the drawn sample and the plug. Any liquid droplets vaporized and drawn into the plug member will contact the hydrophilic particles, which will expand to block passage through those pores while still permitting gas flow through other pores. If the liquid sample itself contacts the plug, enough particles will expand to completely block gas or liquid flow through the plug.

    摘要翻译： 在其相对端开放的中空移液管构件包含多孔的疏水材料力塞，该栓塞安装在其端部之间，以在塞子和管的一端之间限定液体样品室。 插塞材料的孔的至少大部分用液体清除材料的颗粒浸渍，其具有比孔小的尺寸，以允许气体通过塞子被吸入。 液体样品室的预定体积大于由连接到管的相对端的合适的抽吸装置抽取的液体的体积，使得空气间隙将保留在抽出的样品和插塞之间。 蒸发并吸入插塞部件中的任何液滴将接触亲水性颗粒，该颗粒将膨胀以阻止通过那些孔隙，同时仍允许气体流过其它孔。 如果液体样品本身接触插塞，则足够的颗粒将膨胀以完全阻止气体或液体流过插塞。

    摘要： A glass fiber filter mat possessing excellent wet strength which is in the form of a non-woven matrix of glass micro-fibers including polymer micro-bits derived, for example, from a non-brittle expanded, thermoplastic styrene polymer or a flexible foamed polyurethane, the micro-bits being substantially free of intact cells. Also included in the filter mat is a cobeat or intimate blend of cellulose fibers and the polymer micro-bits, which may additionally contain polyester fibers, as well as a combination of binders, viz., polyvinyl alcohol and a melamineformaldehyde resin.

    摘要： A method of receiving retrieved blood from the surgical field of a patient and treating the blood so that it is in condition for direct or indirect return to the patient. The method treats a relatively large volume of blood, which when received in a housing adapted to receive such blood volumes, removes air bubbles and other foreign matter. The received blood flows smoothly both to and from a fibrous membrane interposed in the path of blood flow thereby avoiding bubbling and damage of the blood. Significantly, means within the housing are provided to inhibit clotting of the blood within the housing.

    摘要： 1,063,244. Porous coated sheet material; fluid filtering medium. LLOYD & HILLMAN Ltd. Aug. 6, 1963 [Aug. 6, 1962], No. 30990/63. Headings B1D, BIT and B2E. A medium capable of removing ultrafine particles from fluids comprises a porous base e.g. of paper, and a micro-porous layer adherent thereto. This layer comprises fibres of which a significant proportion extend outwards from the base at an angle of at least 30 degrees and has a maximum pore diameter of 10 microns and a voids volume of at least 75%. It may be made by applying to the base a dispersion comprising a dispersing fluid and particulate fibrous material and controlling the type, size and number of fibres and the state of their dispersion to obtain the required properties when the fibrous material is deposited on the base. Successive layers may be applied in this way. The first applied layer may be a binding layer containing a binder, or the or each main coating layer may contain a binder, e.g. an epoxy resin phenol-, urea-, melamineformaldehyde resins, polyester resins, polyethylene, polypropylene, polyoxymethylene, polyisobutylene, polyamides, cellulose acetate, ethylcellulose, vinyl chloride copolymerised with vinyl acetate, polyvinyl chloride, polyvinylidene chloride, polyvinyl butyral, p.t.F.e., polytrifluorochloroethylene, ligrin-sulphonate resins, starch, casein, terpene resins, polyacrylic resins, alkyd resins, synthetic rubbers such as butadiene-styrene copolymers. The fibrous material may be potassium titanate, asbestos or glass. The dispersion may also include a non-fibrous particulate material, e.g. silica.
