Abstract: 1484864 Iron-containing catalysts IMPERIAL CHEMICAL INDUSTRIES Ltd 25 Nov 1974 [11 Dec 1973] 57321/73 Heading B1E [Also in Divisions Cl and El] A catalyst comprises over 70% w/w (calculated as Fe 3 O 4 ) of metallic iron and/or iron oxide and/or iron nitride and/or iron carbide in the form of approximately spherical granules having a pore volume of at least 0.01 ml/g in pores of radius greater than 104A. Suitably, the granules have a pore volume of at least 0.05 ml/g in pores of radius smaller of 104A and the iron is present in the metallic state. The granular material may contain 1-20% of other iron group metals, especially cobalt. The granules may comprise oxidic material, e.g. Fe 3 O 4 , metallic iron having a passivating outer oxide layer, iron nitride having an outer passivating oxide layer or a carbided iron material. For use in ammonia synthesis, the granules may contain up to 5.0 wt. % calcia, up to 2.0% wt. magnesia, 0.5 to 5.0% wt. alumina and 0.3 to 2.0% wt. potassia. Other oxides, e.g. of Rb, Cs, Be, lanthamides, actinides, Mo or W may be present, as may platinum group metals, cobalt metal or silica. For use as a catalyst for hydrogenating nitriles, the granules may contain up to 5% wt. refractory oxide. For use as a catalyst for the reaction of carbon oxides and hydrogen, the granules may contain alkali. For use as a catalyst for decomposing steam, the granules may contain refractory oxides to increase its resistance to sintering and also oxides reducible more or less easily than iron oxide. The oxidic form of the granules is formed by fusing iron oxide and any other components present, cooling, crushing, selecting a particle size fraction to give the required pore volume, granulating and sintering. Fugitive materials may be added during granulation and then burned-out of the granules during firing to give the required pore volume Pores of steel less than 104A may be formed by reduction of the oxide to metallic iron. The nitride may be formed by reaction of the reduced granules with ammonia. Partial conversion to iron carbide may be effected by treatment with carbon monoxide.

The arm 1b of a transfer device 1 having heads 1c, 1d, is movable between alternative positions (full-line and dot-dash respectively in Fig. 1). In the first position the head 1c is adapted to pick up empty bottles (not shown) from a crate (not shown) held stationary by stops 3 on a conveyer 2. On moving of the heads to the second position, the head 1c deposits the empty bottles on an outgoing conveyer 4 while the head 1d picks up filled bottles from an incoming conveyer 6. On return to the first position, the head 1d deposits the bottles in the same crate which in the meantime has been released by the stops 3, but is now held again by stops 5. At the same time the head 1c picks up a further supply of empty bottles from a successive crate which is again held by the stops 3. In a modification (Fig. 3, not shown), the heads 1c, 1d are mounted on separate, diametrically opposed arms 1b. In a further modification (Fig. 2, not shown) a single arm 1b carrying a single head, rotates successively through the above four transfer stations.

Filed: 1971-12-13
Abstract: 1336199 Brakes; friction clutches EATON CORP 13 Dec 1971 [28 Dec 1970] 57819/71 Headings F2C and F2E An electromagnetically applied friction brake or clutch is rendered capable of stopping in an exact position by slotting the magnet and armature pole surfaces so as to cause a cyclicly varying friction pressure which predisposes the unit to indexing in discrete positions. The magnet is of double pot type comprising a base 12 supporting an outer pole rim 30 toothed at 38 which match teeth 20 at the periphery of the armature plate 16. There is also an inner pole 46 spaced from the part 30 by an air-gap 50 and similarly toothed at 48 to match openings 24 in the armature plate. The two tooth-numbers are different. There is also an intermediate pole ring 58 spaced from the other poles by air-gaps 66, 68 and having no teeth. This ring acts as fluxreturn for the other two when they are energized by their respective coils 70, 72 to draw the armature plate against friction surfaces 40, 42 lying between the pole-rings. The armature is driven at splines 18, and its preferential stopping angles depend on which coil is energized. There may be more than two sets of toothed rims to increase the number of stopping positions, e.g. for indexing in printing.

N-Benzoyl-L- tyrosyl-p-aminobenzoic acid and N-benzoyl-L- methionyl-p-aminobenzoic acid are prepared by benzoylating L-tyrosine and L-methinine respectively, reacting the benzoyl derivatives with N-methylmorpholine and ethyl chloroformate and adding p-aminobenzoic acid and p-toluenesulphonic acid to the reaction mixture. In like manner, N-acetyl-L-tyrosyl-p-aminobenzoic acid and the corresponding N-propionyl compound are prepared using an initial acetylating or propionylating step. N-Ethoxycarbonyl-L-tyrosyl-p-aminobenzoic acid is prepared by refluxing L-tyrosine with ethyl chloroformate, and adding N-methyl morpholine and ethylchloroformate and then p-aminobenzoic acid and p-toluene sulphonic acid monohydrate. N-benzoyl-L- tyrosine-4-amino-3,5-dimethylbenzoic acid is prepared by a method analagous to this second step using benzoyl-L-tyrosine and employing 4- amino-3,5-dimethylbenzoic acid in place of the pamino compound.

Abstract: 1292128 Protective arrangements COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 19 Dec 1969 [23 Dec 1968] 62114/69 Heading H2K An arrangement for controlling the supply to an electronic apparatus S and preventing the completion of the supply circuit to the apparatus when the apparatus is short-circuited or has a low resistance fault, comprises a transistor T2 through which the load current may be supplied to the apparatus, a " control " transistor T1 which is rendered conductive by a control signal at E, a " detecting " transistor T3 which is rendered conducting by T1 only when the resistance at S is sufficiently high, and causes the transistor T2 to conduct. Should the apparatus have a low resistance, T3 is not rendered conducting so that T2 does not conduct and a capacitor C is charged from E until after a delay a Zener diode ZN breaks down. This permits discharge current to flow to the base of a " signalling " transistor T4 to cause it to conduct to provide a fault indicating signal at SN and to render the transistor T1 non- conductive.
