Abstract: 1,060,040. Blood exchange apparatus. MEDIZINTECHNIK LEIPZIG VEB. Nov. 16, 1965, No. 48559/65. Heading A5R. [Also in Division F1] A blood exchange apparatus has two identical pumping systems one being connected to a fresh blood reservoir and the other to a waste blood container. Each system comprises at least one pump element having a chamber therein, an inlet and an outlet conduit connecting with the chamber a valve associated with each of the conduits, and a control element operably associated with the pump element and valves. In operation, the control element is driven so as to cause the chamber of the pump element to act alternately as a suction chamber and a pressure chamber and to selectively operate the valves such that, when the chamber acts as a suction chamber, the inlet conduit is open and the outlet conduit is closed and, when the chamber acts as a pressure chamber, the inlet conduit is closed and the outlet conduit is open. As shown, a typical blood exchange apparatus has two identical pumping systems, each system having two pump elements in the form of pistons 8 and cylinders 9. The pistons of the pump elements of each system move in opposition to one another. Each pump element has a chamber 10 communicating with outlet conduits 11a and inlet conduits 11 b. Fresh blood is stored in reservoir 13 and waste blood is collected in container 14. Each piston has a rod 7 extending through a guide element 6 to slidably engage an abutment body 5, which is carried by a rotatable control element 3, whose rotational speed is adjustable. Reciprocation of the pistons is effected by movement of the abutment bodies along came path 4 on the control element, which is connected to driving means 1 via gearing 2. Each of the conduits 11a, 11b has a spring-loaded pinch valve 16 operated by a magnetic member 15, which is operably associated with a relay 17 controlled by the control element. The left-hand pumping system draws in waste blood via conduit 22 and the right-hand system pumps out fresh blood via conduit 22. Conduits 22 may be connected with a multi-channel catheter 12 or separate catheters. A safety device represented by elements 18, 19, 20, 21 may be used with the apparatus. Elements 20, 21 are associated with the apparatus such that, in the event of malfunction, they will cause an optical and acoustic alarm 18, 19 to come into operation, or will stop the apparatus working.

A radiation-sensitive material comprises a layer substantially free of any water-insoluble radiation-sensitive inorganic salts of silver, which layer is a coated layer of a dispersion of a radiation-sensitive silver-dye compound which has been formed by reacting a cyanine or merocyanine dye with a solution of silver salt. The dispersion may be coated with or without a gelatine and/or polymer binder. When coated without binder the support may be a grained aluminium support. By appropriate combination of dyes used to form the compound and/or couplers, the material may be rendered sensitive to various regions of the spectrum, or may be made panchromatically sensitive or the material may take the form of a coupler incorporated multi-layer colour material. The dye compound may be further optically sensitized. The exposed material is physically developed, e.g. by pressing it into contact with a silver halide emulsion in the presence of a developer and a silver halide solvent. The thus employed silver halide layer may be employed to form a positive image. The material may also be physically developed with copper containing solutions and with physical developers containing colour developers to form coloured images either the material or the developer containing a colour coupler. In a further embodiment the physically developed image may be dissolved away and the unexposed silver dye compound exposed and physically developed to give a positive image. The second physical development may be used to produce a colour image.

Abstract: 1275126 Identification of chromatographically separated substances PACKARD INSTRUMENT CO Inc 8 Oct 1969 [15 Oct 1968 15 Nov 1968 6 May 1969] 49393/69 Heading B1X [Also in Division H5] The coating on the interior surface of an open chromatography column comprises, in addition to an adsorbent such as silica gel or alumina, an intimate mixture therewith and a substance which when heated decomposes the components of the mixture being separated to a standard gaseous substance which can be quantitatively detected; such a substance of particular value in converting organic materials such as lipids to carbon dioxide is cupric oxide. Thus, open column 12 which comprises a sample mixture which has previously been developed in the direction indicated with a suitable liquid eluent is placed in position between spring-loaded holder 39 and seals 42, 44. Carrier gas, e.g. helium, passes from cylinder 22, through the reference side of catharometer 11 and thence through line 10d to and through column 12. At the same time, travelling heater 17 (see Division H5) scans along the column in the direction shown, the effect being to cause the separated bands to be decomposed to a gas which is carried from the tube by the carrier stream, first through a guard furnace 13 to ensure complete conversion, then through drier 14, and finally through the measurement side of catharometer 11. The semi-automatic control arrangements and constructional detail of the apparatus are described. Other specific reactants may be composited with a suitable adsorbent and carrier gas for particular purposes; thus an adsorbent may be used in conjunction with a noble metal cracking catalyst using hydrogen as carrier gas, the effluent then being analysed for methane. Other decomposition reactions such as decarboxylation, deaminoation, dehalogenation, and dehydrohalogenation may be utilised, with detection of the appropriate gaseous product. Instead of, or in addition to, catharometer 11 other detectors may be employed; thus when a radioactive nuclide is present, an appropriate radiation detector may be used.

Abstract: 1,127,506. Boring earth &c. E. E. WARRINGTON. 11 Nov., 1966, No. 50735/66. Heading E1F. A well closing-off tool comprises telescopic members 24, 26 respectively connected to the drill string 12 and the drill bit 14, and internal and external means 30, 28 respectively deformable by movement of the members resultant on lowering the string towards the bit to close the bore through the tool and seal the tool to the well bore. The means 28 is held in sealing position by drilling mud passing through the bore and ports 54, 56 to the means interior. The movement between the members is permitted by a joint J 2  which is arranged so that anti-clockwise rotation of the string after lowering holds the tool in its set condition. When the tool is set a joint J 1  permits the string to be rotated anticlockwise and lifted to disconnect it from the tool. If the bit encounters a high-pressure formation the tool is set to prevent a blow-out until the density of the drilling mud is increased. If a low pressure formation is drilled, loss of mud is prevented by setting the tool and supplying a lighter mud or a mud having sealing properties through the disconnected string which is connected to the tool if drilling is continued.
