Title: Improvements in and relating to drums of winding engines
IPC: B66B15/06
Filed: 1921-08-08
Abstract: 182,416. Schneider et Cie. July 1, 1921, [Convention date]. Winding-gear for collieries and the like ; driving-gear.-In two-part cylindro-conical drums for winding-engines, wedge mechanism is provided for filling the space between the drums to prevent abrasion of the rope. This provides a construction in which the advantage of the twopart clutch drum for facilitating changes in level in the winding is retained, without the disadvantage of rope abrasions as the winding-rope passes over the space between the two parts of the periphery of the drum. In the illustrated form, the drum consists of one part B, B<1>, B<2>. fast on its shaft, and a loose part C, C<1>, C<2>. Toothed rings E', H<1> can be engaged to clutch the two parts of the drum together by sliding the sleeve E axially, the axial movement being effected by a ring of non-rotating screwed rods N operated by nuts formed integral with pinions 0<1>. The pinions all gear with a common toothed wheel, and any one may be rotated by a handle Q to actuate the rods simultaneously. The movement of the rods to engage the clutch also draws the wedges K inwardly into bind.ing relation with the peripheries of the two parts of the drum. To adjust the winding for different levels, the cage connected to the loose section of the drum is supported on the keps, and the sections of the drum de-clutched and un-wedged by the same movement, so that the fast section of the drum can be manipulated alone by the engine. The side faces of the wedges may be lined with friction material.

The casing is divided longitudinally into two parts having flanges secured together by bolts, and is provided at its discharge end with a constricted passage 10 leading to a chamber 9. A screened holder 26 filled with absorbent and oxidizing material extends completely across the discharge end of the chamber 9.

[Also in Group XXIV] A packing arrangement between relatively movable members, such as a piston 2 and cylinder 1, comprises two rings 8, 9 each having a bead portion and an inclined web 8<1>, 9<1>, the rings being located in an annular cavity in one member with their webs directed towards each other to provide a sealing chamber 10. The rings are mounted below a compression ring 6 and are arranged so that, during operation, oil which is collected from the cylinder wall, fills the chamber 10 until its pressure forces the webs 8<1>, 9<1> into sealing contact with the wall and thus prevents the oil from reaching the ring 6. Excessive oil pressure in the chamber may be relieved by providing throttling holes communicating either directly with the chamber or with the seating groove for the bead of the ring 9. The sealing arrangement may also be applied to reciprocating or rotary shafts (Fig. 5, not shown).

The one or more other layers may separate the silver halide emulsion layers, be protective layers or be applied directly to the support. The compounds of the above formula do not split off coloured products on development but split off colourless products and so do not contribute to the formation of a colour image. These compounds prevent the diffusion of the oxidation products of developers from the developed silver halide emulsion layers into the image-receiving layer or into the support or adjacent layers. Specification 1321046 is referred to.

Abstract: 409,177. Valves. STILL, C., Recklinghausen, Westphalia, Germany. Aug. 2, 1933, No. 21719. Convention date, Aug. 5, 1932. [Class 135.] In an expansion valve, past which hydrocarbons, previously heated under pressure in the liquid phase, are allowed to expand for the purpose of cracking and distillation, the valve cone 16, Fig. 1, and its seat 15 are rotated relatively to each other to prevent the accumulation of a carbon or coke-like deposit round the valve or its seat. The valve cone 16 is removably connected to the lower part 17 of a three-part shaft 17, 20, 23 arranged axially in the cylindrical expansion chamber 1, the upper part 23 being carried outside the chamber through a stuffing- box 26 to receive through a ball thrust bearing 30 the load of an adjustably weighted lever 32 and also external driving devices such as the worm gearing 36, 37 driven by an electric motor 39 through spur gearing 40, or alternatively ratchet mechanism, or friction wheel mechanism. The parts 17, 23 have supporting bearings and are connected to the middle part 20 by universal joints, the middle part 20 carrying hinged scrapers 43 which remove any deposit from the chamber walls at the places where the expansion jet impinges. The inlet pipe 13 has an extension 11 enabling it to be supported in the chamber 1 by a member 12.

The desulphurization of the oil can be carried out at 450-750‹ F. and 10-600 p.s.i.g. and the treatment with H 2 S can be carried out at 600- 800‹ F. and 25-50 p.s.i.g. A sulphur containing feed 1 is contacted in the column 18 with a dispersion of the alkali metal 67 and the resultant stream 21 is contacted at 22 with 30-80 mole per cent hydrogen sulphide. The H 2 S-treated stream 24 is separated in the hydrocyclones 27 and 28 into salt slurries 39 and 40 and an oil stream 29 which can be treated with dilute sulphuric or acetic acid 32 and stripped with steam at 37. The salt slurries 39 and 40 are washed with a light hydrocarbon to remove oil and dried at 45, the solids 47 are mixed with sulphur-rich alkali metal polysulphide 49 to produce hydrogen sulphide 50 and sulphurdepleted polysulphide 52 which is passed to an electrolytic cell 56 in which it is converted to an alkali metal stream 62 and sulphur-rich polysulphide 57 which is stripped at 60 to remove sulphur as vapour. Fig. 2 (not shown) illustrates a modification of Fig. 1 in which the oil is desulphurized using an alloy (e.g. Na-Pb or Na-Sn) which is then regenerated with alkali metal from the electrolytic cell. Fig. 3 (not shown) illustrates a modification of Fig. 1 in which the oil-salt dispersion 26, after treatment with H 2 S is not separated in the hydrocyclones (27 and 28, Fig. 1) but is contacted in a tower 80 with a countercurrent of molten sulphur-rich sodium polysulphide 49 and if desired with additional H 2 S 91. Fig. 4 (not shown) illustrates a modification of Fig. 1 in which the oil-salt dispersion 21 is contacted with an excess of H 2 S in the tower 22 and is separated at 82 into a stream 83 of molten sodium hydrosulphide which is either contacted with sulphurrich sodium polysulphide in the polysulphide blending vessel 48 or is contacted with molten sulphur in a vessel 86 to liberate a H 2 S stream 50 and a sodium polysulphide product 99 which is blended with the pyrolysed polysulphide product 49.
