Title: Improvements in or relating to rotary furnaces and kilns
IPC: F27B7/24
Filed: 1928-01-30
Abstract: 310,780. Metals Production, Ltd., (Taplin, T. J.). Jan. 30, 1928. Rotary furnaces. - The joint between the body portion of a rotary furnace and the fixed end plates is made by a gland having fixed and moving bearing- surfaces between which steam or other gas is delivered. As shown in Fig. 3, the body portion 11 of the furnace carries a renewable sectional ring 25 having a machined bearing- surface 26, while the non-rotatable end plate 20 is machined on its periphery and carries a one-piece cast iron sealing-ring 27, which is yieldingly pressed into contact with the bearing surface 26 by adjustable pressure rods 37. Steam grooves 29, 30 are cut in the bearing-faces of the ring 27, the former being of sinuous form to prevent uneven wear of the face 26. Each pressure rod 37 is screwed into a slide block 36 guided by rods united at their outer ends by a yoke 35. Escape of steam is minimized by asbestos packing 41, and in a modification this packing is interposed between the ring 27 and a second undercut ring, on which the rods 37 bear. Charging and discharging.-The devices for feeding and discharging material without allowing access of air may be similar, and may each consist either of a shoot with two alternately-operated bells, or as shown in Fig. 5 of a shoot with two partitions 42, 43, above and below which operate scraper arms 51, and apertured valve discs 50 carried by a rotary shaft 48. The discharge hood of the furnace is slidably connected to the discharge shoot and is pressed into contact with the furnace by a weighted bell-crank lever. At this end of the furnace the sealing-ring 27 is fixed to the hood. At the charging end the feed shoot 54, Fig. 8, may carry a sealing plate 72 which co-operates with a similar plate 73 on the end of the furnace. The space between the plates 72, 73 and the end plate 20 is filled with steam either direct through the connection 74, or by leakage from the joint. Specification 185,242, [Class 82 (i), Extracting metals &c.], is referred to.

Abstract: 1 - Hydroxy - 4 - aminoanthraquinones containing a chlorine atom in the 2- or 3-position and which may be further substituted by halogen, nitro or alkyl are made by adding the elements of hydrogen chloride to a quinone imine of a substituted or unsubstituted 1-hydroxy-4-aminoanthraquinone according to the reaction scheme:- <FORM:1046522/C4-C5/1> by (a) reacting gaseous hydrogen chloride, aqueous hydrochloric acid or a chloride with a solution of the quinone imine in sulphuric acid or (b) reacting chlorosulphonic acid with the quinone imine at 50-120 DEG  C.  The quinone imine is made in situ (1) from a 1-hydroxy-4-amino-anthraquinone or an acylamino, acyloxy or alkoxy derivative thereof by oxidation in sulphuric acid, oleum or chlorosulphonic acid with, for example, manganese dioxide, (ii) by reacting a 1-hydroxy-4-aminoanthraquinone with a 1-hydroxyanthraquinone substituted in 4-position by nitro or nitroso or with the corresponding 1-alkoxyanthraquinone, (iii) from 1-hydroxy-4-hydroxylaminoanthraquinone by rearrangement in sulphuric acid, or (iv) from 4 - methoxy - 1(N) - 9(O) - isoxazoleanthrone or 5 - amino - 4: 8 - dimethoxy - 1(N) - 9(O) - isoxazoleanthrone by hydrolysis and rearrangement in sulphuric acid.  The 1-hydroxy-4-aminoanthraquinones may contain the p-hydroxyamino grouping twice, e.g. as in 1: 5-dihydroxy-4: 8-diaminoanthraquinone. The products dye polyesters in blue shades.

[Also in Division F2] A wood fastener comprises a shank divided longitudinally into two halves 3, 4 of semicylindrical cross-section, a head 6 being formed at one end with a hole 7 therethrough communicating with the axial passage 8 within the two halves, the other end of the shank being pointed and shaped to provide anchoring formations 11. The shaping simultaneously produces a constriction 12 of the passage 8 such that after the fastener has been driven into a piece of wood a nail 16 is driven down the axial passage 8 and spreads the two halves of the fastener apart to cause the anchoring formations to grip the wood. A washer 13 may act as a seal when the fastener is used to secure roof cladding material. The fastener may be formed by bending a length 1 of semi-cylindrical material on itself and then feeding it into a cold heading machine which simultaneously produces a pierced head, pointed end and anchoring formations, Fig. 1. Alternatively, the fastener may be in two separate halves 17, 18, the heading operation producing a shoulder 19, Fig. 3. A perforated cap 20 is bent round the periphery of the head to secure the two halves together. The fastener may also be formed from a length of pipe having a head formed at one end and a barbedlike point at the other. The wall of the pipe is split along at least that portion of the shank where the bore is constricted.

A method of making a product 10 having a core of aluminium or alloys thereof, clad with a bonded outer layer of titanium or alloys thereof comprises heating an aluminium core 2 to between 700‹ and 1050‹ F., placing a sheet of titanium 4 at ambient temperature or at a temperature below its hot forming temperature in face-to-face contact therewith and immediately passing said members conjointly through a rolling mill to obtain a reduction in thickness of said core body of between 30% and 80% in one pass. The materials may be in the form of sheet or strip fed from coils, plate or slab and the titanium member which is bonded to one or both sides of the core is preferably of a thinner sections than the core material. Preferably the core is heated to 950/1000‹ F. The members are cleaned with a conventional solvent by sand blasting or wire brush, followed by alkali treatment and acid pickling, for example an alkali bath of 50% KOH and water and an acid bath of 8% HNO 3 , 1 % HF balanced water. A hand mill may be used in which case the titanium sheet is bent transversely about its centre about a 0À25 die rod into a V-shape and the heated core inserted therein immediately prior to rolling. The composite member may be reheated to 900/1050‹ F. and rerolled to effect a further reduction of up to 15% of the aluminium core and stress relieved or annealed at 900/1000‹ F. for 2 hours. In an example an aluminium plate 0.25 inch thick by 16À5 inches by 17À5 inches was bonded to titanium sheets 0.020 inch thick by 17À5 by 48 inches long between a 2 high rolling mill having 29 inches diameter rolls rotating at 32 r.p.m. to effect a reduction of the core to 0.132 inch Protective steel sheets may be placed over the titanium during rolling.

Abstract: 698,434. Cables. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Feb. 14, 1962 [Feb. 15, 1951], No. 3717/51. Class 36. An electric cable body comprising one or more conductors surrounded by material of which at least the outer part is applied by extrusion, and which has a series of shallow grooves extending longitudinally of its outer surface, is enclosed in a tightly fitting metal sheath applied by a method other than extrusion. A conductor 1 may be surrounded by an extruded body 2 of polyethylene, the outer surface of which forms grooves 3 and projections 4 extending longitudinally of the cable. The body may be drawn into an oversized metal tube which is then drawn down to make a closely fitting sheath 5 (Fig. 3). This deforms the outer parts of the projections 4 and forces the material therefrom sideways into grooves 3, small portions 6 of the grooves remaining unfilled. Alternatively, the sheath may be made by bending a metal strip about the cable body and soldering or welding the longitudinal seam thus formed, the deformation of the projections 4 taking place during the bending of the strip. The depth of the grooves 3 is made at least equal to twice the sum of the tolerances given for the diameter of the cable body and the internal diameter of the metal sheath.
