Title: Method and apparatus for automatically tying up coils or bundles of wire or other materials
IPC: B65B13/02
Filed: 1965-06-04
Abstract: 1,093,911. Coiling; twisting wires together. WAFIOS WAGNER, FICKER & SCHMID G.m.b.H. [trading as WAFIOS MASCHINENFABRIK WAGNER, FICKER & SCHMID]. June 4, 1965 [June 10, 1964], No. 23920/65. Heading B3E. [Also in Division B8] A deflecting surface 3, Fig. 1, causes a wire 102 or other binding material to be deflected round a group of articles, e.g. a coil of wire, a bundle of rods, to form one or more laterally adjacent circular windings; these are then tightened round the articles and the ends of the wire twisted together. In the embodiment a coil 100 to be tied is placed against an adjustable stop (57), Fig. 7 (not shown), so that the article is centred relative to the twisting axis of the machine. The operation, started by a foot switch, begins with a longitudinally slidable member (1), Fig. 2 (not shown), carrying the wire looping tools 3, 4 and 5, moving into position. Feed rollers 13, 14 feed a length of wire through guides 10, 6 between rollers 4, to the deflecting means 3, whose deflecting surface is adjustable in inclination to allow coils of varying diameters to be made. An adjustable switch on the feeding control causes the feeding rollers 13, 14 to stop when the required length of wire has been fed through. The slide is then retracted to release the loop so that it is held only by the wire extending to the supply. A twisting shaft 28 Figs. 8, 9 (latter not shown), carrying twisted tongs (17), (18), Fig. 5 (not shown), is then moved upwards and the tong arms (17), (18) are closed so that conical projections on the arms engage with each other within the circular wire loop, Fig. 3 (not shown). Simultaneously jaws 24, 25 are moved forwardly to the position in Fig. 8. The slide member (1) is then retracted and a cutter 7, mounted on the slide, cuts off the wire at the end of the guide 10. The wire loop is then drawn tightly round the articles by the downward movement of the twisting shaft 28 and at the same time the twisting jaws 24, 25 move towards each other to press into parallel relation the sides of the loop above the projections. The twisting shaft 28 and the twisting tongs (17), (18) are finally rotated to twist the ends of the wire together, Fig. 6 (not shown). Finally the tongs. (17), (18) open and the twisting shaft 28 moves back to its original position. Simultaneously the jaw 24 is retracted while the jaw 25 continues to move forwardly in order to bend the twisted ends of the wire towards the centre of the coil. If the length of the twisted end is too long, an additional cutter 8, acting against the jaws 24, 25, may be provided on the slide member (1), to out off the end of the twisted end.

Title: Improvements in or relating to operators' sets for telephone systems
IPC: H04M5/04
Filed: 1935-08-29
Abstract: 459,198. Exchange systems. TELEPHONE MANUFACTURING CO., Ltd., Martell Road, West Dulwich, London, FLINT, J. G., Kenlyn, Station Road, Orpington, Kent, and RYALL, L. E., 9, Lowlands Road, Eastcote, Pinner, Middlesex. Aug. 29, 1935, No. 24189. [Class 40 (iv)] An exchange operator is provided with a loudspeaking telephone set in addition to or in place of the ordinary set, amplifying equipment being associated with the set itself or with the cord or other exchange connecting circuit. The invention is primarily applicable to systems employing a single operator but may be used where several operators are employed if they are not close together. An ordinary microphone may, however, be used for speaking. In the arrangement shown, suitable for systems in which the subscribers have individual amplifiers for loud-speaking sets or in which loud-speaking facilities are not provided, the operator's loud-speaker LS and microphone M are associated with amplifiers AM, BM connected over a hybrid coil to the speaking key K. By using the twoway amplifying arrangements described in Specification 415,767, 416,372, 430,158, or 430,567, the hybrid coil may be dispensed with, and arrangements may be provided to prevent room noise from exercising control. As applied to the amplifying cord circuit described with reference to Fig. 2 of Specification 445,860 which provides for connecting one loud speaking substation to another or to an ordinary substation, the operator's ordinary set and the attenuating pad therefor are replaced by a loud-speaking set. The loud-speaker and microphone, in this case, may be connected up in series or parallel or over a hybrid coil, or to separate windings of a transformer, or the loud-speaker may be connected in series with the secondary of a microphone transformer. Alternatively, the directional switching arrangements described in Specification 444,598 may be used if the operator is subjected to steady background noise. Moving coil or other high quality microphones may be used.

Title: Improvements in or relating to the manufacture and production of thermoplastic products from fatty oils
IPC: C09F5/00
Filed: 1929-08-08
Abstract: Thermoplastic and vulcanizable products are made from unsaturated fatty oils, especially drying and semi-drying oils, by (1) polymerizing the oil by heating preserably above 200 DEG  C. and under reduced pressure, in the presence of a non-oxidizing gas, and then (2) thickening the polymerized oil by dissolving a salt of a higher fatty acid therein.  The soap may be added prior to, during, or after the polymerization.  Linseed, soya bean, cottonseed or tung oil is heated at 250-300 DEG  C. under a pressure of 15 to 145 mm., with sulphur dioxide, sulphuretted hydrogen, carbon dioxide or hydrogen (in the absence of hydrogenating catalysts) and thereafter the polymerized oil is heated with a soap, preferably of a saturated acid e.g. sodium or magnesium stearate.  During heating the presence of air is avoided.  The product may be vulcanized by heating with sulphur or sulphur chloride, and if desired in the presence of accelerators e.g. mercapto benzthiazole or activators e.g. zinc oxide and used as a rubber substitute.  The products may be compounded with solvents, cellulose esters and plasticizers to form a varnish in which fillers or pigments may be incorporated.  Specification 214,679, [Class 91, Oils &c.], is referred to.

Title: Process for the production of hydroaromatic hydrocarbons from coal tar and coal tar fractions and products therefrom
Inventor: MCNEIL DONALD
IPC: C10G65/08
Filed: 1952-10-08
Abstract: Coal tar, coal tar fractions and aromatic hydrocarbons derived from coal tar are hydrogenated in two stages, the first using a sulphur-resistant catalyst at 350-450 DEG  C. and a hydrogen partial pressure of 0.5-70 atmospheres to destructively hydrogenate sulphur compounds and hydrogenate part of the aromatic hydrocarbons, the second being a non-destructive, complete hydrogenation of the product entirely in the vapour phase at 200-500 DEG  C. and 20-100 atmospheres hydrogen partial pressure using a catalyst consisting of one or more Group 8 metals.  The coal tar fractions used may comprise mixtures of aromatic hydrocarbons with partially hydrogenated derivatives, paraffins, olefins, and naphthenes.  The first stage may be effected in liquid, vapour or mixed phase, continuously or batchwise. Catalysts include molybdates and thiomolybdates, supported or not, especially cobalt molybdate on alumina.  The hydrogen partial pressure used increases with the complexity of the sulphur compounds present.  The exit gas may be re-used after removal of H2S.  The products are treated, if necessary, to remove H2S and completely hydrogenated in the second stage as in Specification 761,755.  Excess hydrogen from each stage may be recycled.  In examples: (1) sublimed naphthalene is desulphurized by hydrogenation at 375 DEG  C. and 32 atmospheres using cobalt molybdate, and the product vaporized in hydrogen at 300 DEG  C. and 32 atmospheres in the presence of nickel on kieselguhr to yield decahydronaphthalene; (2) a 200-280 DEG  C. coal tar fraction freed of tar acids and bases is similarly desulphurized but at 410 DEG  C., and then hydrogenated, after a caustic soda wash, to yield naphthenes; (3) a 300-380 DEG  C. fraction is similarly treated, first at 410 DEG  C. and 42 atmospheres, and then at 300-330 DEG  C. and 32 atmospheres, the product then being recycled to the second stage at 360-370 DEG  C. and 55 atmospheres; (4) a 120-200 DEG  C. fraction is treated first at 410 DEG  C. and 20 atmospheres, then at 270-280 DEG  C. and 30 atmospheres.
