Title: A process for the manufacture of organic electro-neutral salts from onium compounds
IPC: C07F9/54
Filed: 1953-12-16
Abstract: Neutral salts are obtained by reacting water-soluble salts of disulphonimides or N-acyl-sulphonamides with quaternary ammonium, phosphonium or arsonium or ternary sulphonium salts having attached to the central atom a radical or 6 or more carbon atoms. The latter radical may be alkyl, cycloalkyl or aralkyl and the chain may be interrupted by hetero-atoms such as oxygen, sulphur or nitrogen, and may contain substituents.  The radicals attached to the sulphonimide or acylsulphonamide groups may be alkyl, cycloalkyl, aralkyl or aryl and may be substituted or interrupted as above.  Examples show the preparation of (1) dodecyl-pyridinium salt of dioctadecyl-disulphonimide; (2) dimethyl-cyclohexyl-octadecyl-ammonium salt of ditolyl-disulphonimide; and (3) dimethyl-isododecyl-sulphonium salt of di-p-tolyl-disulphonimide.  Other suitable cations are trimethyl - hexyl - ammonium, trimethyl-dodecyl - ammonium, trimethyl - octadecyl-ammonium, dimethyl - dioctadecyl - ammonium, dimethyl - dodecyl - benzyl - ammonium, hexylpyridinium, hexylquinolinium, octadecyl-pyridinium, octadecoxy - carbonylmethyl - trimethyl - ammonium, dodecoxycarbonylmethyl-pyridinium, naphthenoxycarbonylmethyl - quinolinium, abietyloxycarbonylmethyl - quinolinium, di - (dodecoxycarbonylmethyl) - dimethyl - ammonium, octadecylamino - carbonylmethyl - trimethyl - ammonium, octadecylanilino - carbonylmethyl - pyridinium, dodecoxymethyl - trimethyl - ammonium, octadecylthiomethyl - triethyl - ammonium, stearoylaminomethyl - pyridinium, octadecoxy-carbonylamino - methyl - pyridinium and the corresponding phosphorus and arsenic compounds, e.g. dodecyl-trimethyl-phosphonium and octadecyl - benzyl - dimethyl - arsonium; these compounds can contain further oniom groups.  Other suitable sulphonamide derivatives are butyl-hexyl, dioctyl, octyl-octadecyl, cyclohexyl - dodecyl, di - alkylphenyl (C6-C18 alkyl) and dinaphthyl disulphonimides, and N-acetyl, N-isobutyryl, N-lauroyl and N-naphthoyl - benzenesulphonamide, N - propionyl-dodecylbenzenesulphonamide and N - benzoyl-laurylsulphonamide.

Abstract: 1468113 Making commutators; forging; extruding KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE AG 27 Aug 1975 [27 Sept 1974] 35362/75 Headings B3A B3H and B3P A commutator is provided by extruding a cup with inwardly projecting ribs from a copper or copper alloy blank, punching out the starshaped portion of the bottom which is defined by the ribs, reducing the outside diameter of the product by extrusion while reducing the spacing between the ribs, filling the recesses between the ribs with insulating material, and externally machining the result until the insulating material is exposed. Apparatus for carrying out the first three stages includes a single press having ribbed rams or punches and manual or automatic transfer of the blanks between the stages. Fig. 1a shows on the left a blank 1 located in die 4 having an ejector 5. On the right, ram 6 having ridges 7 is shown at the end of its stroke having formed a cup 2 having recesses 8 between ribs 3. The bottom of the cup is then punched out by a punch having ridges like those of ram 6, so that the ribs 3 are not reformed. The product 12, Fig. 3a is then extruded through die 13 having reduced portion 15, by tool 14 having ridges 7 of less thickness than those of the ram and punch of preceding stages. At the same time, projections 16 on the die form flutes 17, and the internal diameter is enlarged slightly, whereby the rib formations of Fig. 3c result. A plurality of the resulting tubes are then mounted on a shaft, the recesses filled with insulating material, and the tubes are externally machined to expose the material. The shaft may then be removed, or divided to provide a shaft for each commutator.

To provide for greater flexibility in the bead and crown centre regions, a pneumatic tyre is formed from a carcass band of two plies 6, 5 of parallel cord fabric extending from bead to bead with their stepped side edges 10, 11 folded back around bead cores 7 to terminate just short of each other at 12, 13 in the crown centre on opposite sides of the mid-circumferential plane, the gap between the side edges being bridged by two breaker plies 18, 14 of parallel cord fabric disposed respectively immediately above and below the said edges. The carcase plies may have a cord angle of from 35 degrees to 50 degrees and the breaker ply cord angle may be 10 degrees to 25 degrees all with the mid-circumferential line. The tyre may be completed by two bead to bead carcase plies 19, 20 the edges of which terminate at the bead toe, and a further breaker ply 21. Larger tyres may comprise two further carcase plies 23, 24 wrapped around additional bead cores 25 with their stepped edges 29, 28 terminating in the crown region but spaced by wider gaps 30, 31 than those 12, 13 of plies 5, 6, there being a breaker ply 32 immediately below the edges to bridge the gaps 30, 31, and the tyre being completed by two carcase plies 35, 36 having their edges terminating at the bead toe.

Abstract: 1398714 Welding by pressure; upsetting SIMON-CARVES Ltd 14 July 1972 [29 July 1971] 35705/71 Headings B3H and B3R In forming an anchorage abutment on the end of a stranded pre-stressing cable, 10, heat is applied to the end of the cable by producing friction thereat to cause the strands in the end region to become welded together and simultaneously or subsequently causing a portion of greater axial cross-sectional area than said cable to be formed integrally therewith to form the anchorage abutment. In one embodiment a carbon block is rotated at high speed in contact with the end face of a stranded cable 10, Fig. 1, and the cable, heated by friction, forms a flash or burr 11 which when the block is withdrawn forms an anchorage for use in reinforcing concrete. In other embodiments a slug of weldable material is rotated in frictional contact with the end of the cable to become welded thereto. The slug 12, Fig. 2, may be the same size as the cable when the flash 13 forms the abutment or may be of larger cross-section when the cable end engages the plane end face of the slug, a recess in the end face or a projection extending from the end face of the same size as the cable end. The slug may have a cold formed button head 22, Fig. 6, and a projection 21 which is friction welded to the cable end or alternatively the button head may be welded to the cable end. The button head may be formed after welding.
