Abstract: 1448800 Bipolar electrolysis electrode SWISS ALUMINIUM Ltd 12 Aug 1974 [13 Aug 1973] 35375/74 Heading C7B The electrode, useful in melt-electrolysis of fluoride or oxide melts in Al production, comprises a conductive ceramic oxide anode surface, a conductive cathodic surface of a different material and an optional intermediate layer. The ceramic oxide may be compressed and sintered being based on oxides of Sn, Fe, Cr, Co, Ni or Zn with the optional addition of 0À01-20 wt per cent of one or more oxides of Fe, Sb, Cu, Mn, Nb, Zn, Cr, Co, W, Cd, Zr, Ta, In, Ni, Ca, Ba or Bi. Alternatively this oxide may be applied as a coating to the intermediate layer which may be of Ag, Ni, Cu, Co, Mo or a conductive carbide, boride, nitride or silicide. The cathodic material, which may also optionally be a coating, may be graphite or a boride carbide, nitride or silicide of C, Si, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta or W. The components of the cell may be held in a non-conducting frame of e.g. BN, Si 3 N 4 , Al 2 O 3  or MgO, or in recesses in the cell wall via the support of electrolyte solidified by passage of a cooling medium through the cell wall adjacent the recesses. In use in a cell the anode, cathode and bipolar electrodes are parallel and may be inclined to the vertical. Electrolyte preferably covers the working anodic bipolar surface.

A disc valve comprises a cylindrical chamber 1 having therein a free foil type of disc 5, supply and outlet lines 3 and 4 respectively both of which intersect one circular surface of the chamber, and a signal line 2 which intersects the opposite circular chamber surface, the supply and signal lines being interconnected by a duct 7 having therein a restriction 8 and the signal line having associated therewith a plugging member 6 in the form of a close coiled helical spring 6. With the spring in its normal compressed state in which the signal line is closed, fluid pressure from the supply line acting on the upperside of the disc forces the same to close the passage between the supply and outlet lines 3 and 4 respectively, this being made possible by the inclusion in the outlet line of a restricted bleed passage 11. Deflection of the spring, so as to open the passage between lines 3 and 4, may be effected by means of a solenoid (Fig. 3, not shown), pneumatically by means of a diaphragm (10, Fig. 4, not shown), or by means of a movable vane or disc connected to a supply of air (Fig. 5, not shown). In alternative embodiments (Figs. 6 to 10, not shown), closure of the signal line may instead be effected by means of a tyre valve (13), a pneumatically expandable diaphragm (14), a reciprooable piston (17) or by a machine part (19 or 20) movable respectively parallel or transversely to the signal line axis.

Abstract: 1288003 Determination of complementfixing antibodies BAXTER LABORATORIES Inc 23 July 1970 [7 Aug 1969] 35650/70 Heading B1X Complement-fixing antibodies in biological fluids are determined by mixing predetermined amounts of complement and complement fixing antigen with the biological fluid sample, in predetermined proportions, and reacting the agar gel containing the sensitized erythrocytes, suspended in known concentration in a gel medium. A gel plate for use in the test carries agar gel containing the sensitized erythriocytes, preferably in proportion 0.05 to 5% erythrocytes in a medium which is 0.1 to 5% agar. The complement may be whole guinea pig serum or may be obtaining from humans or rabbits. Use of Kolmer antigen is exemplified; others are mentioned. The sensitized erythrocytes may be sheep cells sensitized with rabbit or other anti sheep cell serum. Various gel media are mentioned. The gel plate may be packaged in plastics film or metal foil, optionally in combination with complement fixing antigens, complement and control samples and capillary tubes. In carrying out the test, the reactionmixture is introduced into wells in the gel and the gel plate incubated. A clear lysis zone around the well indicates absence of antibody in the sample; in the presence of antibody a precipitin ring forms.

Preferably the quinoidine is first melted and powdered sulphur is stirred into the molten mass with continued heating until the temperature rises suddenly to 135--140 DEG C., the mass being kept at this temperature for 15 minutes and then cooled. The amount of sulphur employed is 5-20 per cent, preferably about 15 per cent, by weight.  The Specification as open to inspection under Sect. 91 comprises the manufacture of derivatives of cinchona bark alkaloids in general by heating with sulphur a cinchona bark alkaloid (other than quinine) or a mixture of alkaloids (including quinine if desired), or by heating with sulphur chloride or other agent furnishing sulphur a cinchona bark alkaloid or mixture thereof in presence or absence of a common solvent.  This subject-matter does not appear in the Specification as accepted.  Metal pickling.--Metal pickling baths comprise a dilute non-oxidizing acid, e.g. sulphuric, hydrochloric, acetic or formic acid, or an aqueous solution of an acid sulphate, containing a small proportion, e.g. 0,02--1 per cent by weight, of the sulphurized quinoidine bodies described above as inhibitors. Examples describe use of these compounds in the treatment of: (1) steel with 6 per cent sulphuric acid at 180 DEG F.; (2) black sheet steel with 15 per cent hydrochloric acid at 80--90 DEG F.  The Specification as open to inspection under Sect. 91 comprises the use as inhibitors of sulphurized cinchona bark alkaloids in general.  An example is given of the use of sulphurized cinchonine, whilst sulphurized quinine and quinidine are also specified.

Abstract: 1,012,467. Hoop tightening devices. BORKEWANNER A.G. Sept. 4, 1964 [Sept. 4, 1963], No. 36456/64. Heading F2G. A pneumaticallyoperated hoop - tightening and clamping device comprises a housing 3 containing clamping, 5, and tightening means, 14, a hollow handle 1 provided for the housing, connecting means 7 for an air supply line 8, the connecting means being mounted forwardly of the centre of the handle in the direction of the housing, the connecting means extending transversely to the longitudinal axis of the handle, a motor 2 contained in the handle and at least one air channel disposed such that the supply of air flows from the front towards the rear of said motor. As shown, the clamping means 5 fastens a sleeve 16 about the hoop and is operated by compressed air acting on a piston in a cylinder 6. A driving roller 14 which can be raised by lever 9 to allow entry of the hoop tensions the hoop and is driven by the motor 2. The air supply to the cylinder is controlled by a push-button valve (Fig. 2, not shown) and a push-button valve 11 controls the supply to the motor. The push-button releases a ball valve to allow air into a longitudinal channel 36 to an opening 38 and into further longitudinal slots 40 which act as inlet channels for the compressed air motor 2. The rotor 116 of the motor carries a plurality of radial sliding vanes 42 displaceably guided in slots in the rotor. The rotor is eccentrically mounted with respect to a sleeve 40 and the slots 40 are located where the rotor jacket lies closest to the sleeve, so that the compressed air can expand during rotation of rotor 116. The air flow can be divided, part to flow through outlet slot 44 and thence through channels and out of the handle in the vicinity of the housing and part to flow through a perforated plate 48, although this plate can be dispensed with and the entire flow pass through slot 44. The rotor supported by ball-bearings 37, 39 has a pinion 18 meshing with planet pinions 20 each of which is seated upon a bolt 22. The planet pinions are formed as twin wheels meshing with an internally toothed sleeve 41 and an internally toothed or geared hollow wheel 24 rotatably supported in the housing and carrying a drive-shaft 26 connected via a worm drive with the driving roller 14 to step down the running speed of the motor about 50: 1. The air hose may contain an oil atomizer to inject lubrication oil to the motor.
