Title: Calcining kiln
IPC: B01J6/00
Filed: 1951-04-06
Abstract: 696,095. Rotary kilns. DUBE, J. B. April 6, 1951, No. 8073/51. Class 51(ii) A rotary kiln for calcining ores and minerals comprises a stationary feed section 11 lined with water tubes 33, Fig. 6, and formed with a feed shoot 34, a rotary furnace tube 10 having a refractory lining from which project spirally disposed chrome steel lifters 21 extending throughout the tube and being spaced therefrom with annular dams 26 defining the hottest part of the tube, a fixed casing head 14 carrying a burner 15 preferably supplied with pulverized coal, and a rotary cooler 16 formed with spirally arranged lifters 29 and cooled externally by water sprinkled from a pipe 30 and internally by air from a fan 32. The furnace tube 10 comprises an outer steel shell to which are welded brackets 22 supporting the lifters 21, a layer of self-hardening plastic insulating material 23 filling the space between the shell and the lifters, refractory bricks 24 cemented to the material 23, and; covering the brackets 22 and the bricks 24, an inner lining of graphite 25 which inhibits the adherence of hot plastic ores. The dams 26, Fig. 3, are formed of a metal shell with a gradual slope a on one side and a steep slope b on the other anchored to the outer shell by brackets 28 and enclosing a mass of refractory material 27. These dams have the effect of slowing the passage of and thickening the mass of ore in the hottest zone of the kiln inhibiting the formation of rings of plastic ore, and the slope a of the lower dam tends to confine the flame to the axis of the kiln thus preventing overheating of the charge. Waste gases pass through the feed section 11 to a chimney 12 and hot water from the pipes 33 is used with advantage in a separation cone and shaker screen (not shown) in which clay is washed from the crude ore. Rapid cooling of the treated ore from approximately 1550‹F to 200‹F in the cooling section 16 causes some spalling of the charge and dust so formed is carried off by the air from the fan 32 to precipitators at the discharge end of said cooling section.

Title: Improvements in and relating to automatic brakes and soundbox lifters for gramophones and like sound reproducing machines
IPC: G11B3/58
Filed: 1929-03-16
Abstract: 330,324. Dakin, H. E. March 16, 1929. Brakes, arrangement and disposition of; raising, positioning, and lowering ,3ound-boxes. - Relates to automatic brakes and sound-box lifters of the kind in which a brush or the like is pivotally mounted so that the bristles engage with the record track grooves that have already passed the needle, and the brush carries a catch controlling a pivotally-mounted brake device, the arrangement being such that when the end of the recorded track is reached the relative movement of the brush and needle causes the catch to release the brake device which then drops on to the record and brakes it and at the same time raises the sound-box. According to the invention, the catch device is arranged so that it will release the brake device upon relative movement of the stylus and brush in either direction. As shown, a brush 36, Figs. 1 and 2, is pivoted at 33 to the holder for the stylus 32 and has a catch consisting of two hooks 45. Pivoted to a framework 39 fixed to the soundbox 30 is a member 41, 42, one end of which engages the catch hooks 45 and the other carries a member 44 of braking material. The member 42 is engaged with one or other of the hooks 45 according to whether or not the record has a spiral leading from the end of the recorded track towards the centre. The hooks 45 may project towards one another and be positioned slightly apart, or the catch may be arranged below the brush pivot 33. In a modification, the member 66, Figs. 8 and 9, carrying the brush is U-shaped and pivots on a projection 65 on the sound-box. Arms 68 carrying the brake member 44 are pivoted to the limbs 67 of the member 66 and have a projection 69 co-operating with a projection 70 on the part 65. Relative movement between the stylus and sound-box causes disengagement between the projections 69, 70, and lowering of the brake 44 on to the record. In another modification, the arms 68 are pivoted to a projection on the sound-box and the projection' 70 is arranged on the brush support 66, a, spring being provided to keep the latter in a central position. In another modification, the brake 44 is cam-shaped and tha brush is yieldingly held in its holder. In another modification, in which the sound-box is of the type in which the stylusholder 92, Fig. 14, is pivoted between lugs 93, one of the latter is extended and carries spindles 94, 99, arranged mutually at right-angles. The spindle 94 carries a brush holder 95 and a catch 96 at its ends and is spring urged to a central position. The spindle 99 carries the brake member 101, the latter having a projection 102 cooperating with the catch 96, and a re-setting handle or projection 103. The contacting parts of the members 96, 102 are bevelled so that the apparatus may be re-set by turning the soundbox upside-down. A similar arrangement may be applied to the other modifications described.
