[Also in Division B6] A machine for preparing binding edges of a stack of sheets forming a book filler comprises a suction fan 1, Fig. 2, having a number of radial blades 3 and a hub 2 which is provided with air inlet ducts 12, the hub supporting a rotary cutter 4 which trims the edges of the sheets or removes the folds from signatures and a number of peripherally spaced teeth 6 which cut grooves in the binding edges, whereby the suction draws the fibres to prepare the edges for application of glue. The stacked sheets are passed across the cutter 4 through an opening 18 formed between a pair of adjustable plates 9, 16. The fibres may be drawn by application of an electrostatic field to the fibres. The field may be generated by friction between the cutter and the paper of the sheets and the fan impeller is mounted in the shaft through the intermediary of an insulating bush (not shown). The prepared book fillers B, Fig. 4, are advanced past a further electrostatic field generator 15 to a glue applicator comprising a pair of counter-rotating rollers 23, 24 whose axes are skewed relative to the direction of movement of the book fillers B.

Abstract: 1,250,145. Superconductor coils. E. KANDA. 20 Feb., 1970 [9 June, 1969], No. 8346/70. Headings H1K and H1P. Each turn of a superconductor coil comprises layers arranged in the following sequence:- (a) a diffusion barrier layer; (b) a superconductor material produced by subjecting a laminate of sheets of metal or alloy in a ratio corresponding to the composition of the material to a thickness reduction and a heat treatment; (c) a second diffusion barrier layer; and (d) a stabilizing layer comprising a normal conductor. As shown, Fig. 2, a plurality of thin Nb and Sn sheets 9 are cleaned, stacked, and rolled to produce a laminate on both sides of which are placed Nb sheets 10 to act as diffusion barriers and Cu sheets 11 to act as stabilizing layers. A stainless steel sheet 12 is placed on one side of the laminate to form a high resistivity layer and the composite is wound on to a Cu pipe, inserted into a second Cu pipe and subjected to a thickness reduction by extruding and working to enlarge the diameter of the inner pipe. The assembly is then inserted into a stainless steel pipe, extruded and heat treating to react the thin Nb and Sn sheets to form Nb 3 Sn. The coil may be cut into suitable lengths which are re-assembled with spacers and connected electrically in series to form a solenoid. In a second embodiment the thin sheets are of Nb and Al 20% Ge alloy the ratio of the thicknesses being selected so that when reacted Nb 3 Al 0À8 Ge 0À2  is formed. In a further embodiment the thin sheets are of Nb and Al, the diffusion barrier layers are of Nb and a composite comprising a layer of Ni sandwiched between two Cu layers is placed on both sides of the structure to provide normal and high resistivity layers, and the resulting material is wound on to a copper rod. The materials used to form the superconductor layer may be selected from Nb, Sn, Al, V, Zr, Ti, Pb, Ge and alloys of these, the diffusion barrier layers may be of Nb, Ta, V or the Ti, stabilizing layers may be of Cu, Al or Ag, and the high resistivity layers, if used, may be of stainless steel, Ni, Zn or Sn and may react with the stabilizing layer to form a high resistivity alloy layer. The adjacent ends of two coil sections may be worked to produce a desired surface configuration, Fig. 4a (not shown), or a transverse aperture can be bored through a coil section which is then cut in two through the aperture and reassembled with an insulating spacer between the two parts and with shorter coil sections placed in line on either side separated by insulating spacers, Fig. 4b (not shown).

Abstract: 1,252,536. Detecting the presence of current. UNION CARBIDE CORP. May 5, 1970 [May 6, 1969], No.21466/70. Heading G1U. The presence of current above a predetermined minimum value in a cable C, Fig. 2, is detected by applying the potential drop across a small length of the cable, e.g. two feet, to an operational amplifier 25 arranged with positive feedback R7 to function as a threshold device with hysteresis. The output of the operational amplifier is rectified D5 and smoothed C3, so that either D.C. or A.C. current may be detected, and used to control a relay CR via a transistor 21. The circuit is initially set up by arranging for no current to flow in the cable, adjusting a potential divider R6 to produce a suitable output voltage from the operational amplifier, e.g. 4v., and adjusting the ratio of the feedback resistors R7, R8 to give the desired threshold voltage e.g. 4 mv. which may correspond to a current of 20A, at the input of the operational amplifier. In operation the output of the operational amplifier will normally be positive at about 4 v., and when the cable current exceeds 20A, so that the input voltage to the operational amplifier exceeds 4 mv., the operational amplifier will switch, becoming saturated in the opposite direction and producing a negative output of about 4v.

A process for the preparation of a detergent composition with improved free-flowing properties comprises heat-drying an aqueous slurry containing a water-soluble alkali metal salt of nitrilotriacetic acid, an alkali metal tripolyphosphate, a non-ionic synthetic detergent, an anionic synthetic detergent and from nil to less than the total amount of the alkali metal soap required in the final composition to form a powder, and then adding the balance of the soap in the form of shaped solids to the heat-dried composition. The aqueous slurry may contain not more than half the total amount required in the final composition, whilst the best results are obtained if the slurry does not contain soap at all and all of the soap is added afterwards to the heat-dried product. Suitable shaped solid forms for the balance of soap are noodles, flakes, ribbons, threads, granules, pellets and small spheres. The flow properties of the heat-dried powder are not affected by the incorporation therein of these shaped solids. The soap may also contain perfumes, germicides, colouring material, fluorescers, enzymes, tarnish inhibitors and corrosion inhibitors. The aqueous slurry may be prepared in any conventional manner by mixing the constituents with sufficient water, generally 45-55% by weight of the final slurry. The heat-drying is preferably carried out in a spray-drying tower. The alkali metal polyphosphate is preferably sodium tripolyphosphate and the detergent composition may contain nitrilotriacetic acid and sodium tripolyphosphate in an amount of 20-50% by weight of the final composition, in which the nitrotriacetic acid and sodium tripolyphosphate are preferably in a molar ratio of 4 : 1 to 1 : 4. Preferred non-ionic synthetic detergents are condensation products of alkylene oxides with organic hydrophobic compounds, e.g. condensate of nonylphenol and 10 molecules of ethylene oxide, preferably in an amount from 1-10% by weight of the final composition. Preferred anionic synthetic detergents are the alkali metal salts of the reaction product of sulphating or sulphonating agent with an organic sulphatable or sulphonatable compound, e.g. sodium alkylaryl sulphonate, preferably in an amount of 2-20% by weight of the final composition. Conventional soaps are used, preferably in an amount from 1-10% by weight of the final composition. Additional ingredients specified are water glass, sodium carboxymethyl-cellulose, soda ash, sodium toluene sulphonate, EDTA sodium thiosulphate and sodium perborate.
