Title: Improvements in and relating to refractory bricks for use in suspended furnace roofsand other mechanically supported furnace walls
IPC: F27D1/02
Filed: 1945-06-26
Abstract: 600,630. Refractory bricks. HEUER, R. P. June 26, 1945, No. 16261. [Classes 51(i) and 51(ii)] [Also in Group V] An unburnt refractory brick is prepared from a refractory substance by moulding under pressure and provided with an insert having a formation suitable for engagement with a supporting member or hanger in a furnace, this insert being embedded in the refractory substance during the moulding of the brick, the refractory substance and the insert being enclosed on all sides in the mould at the completion of the moulding. Fig. 2 shows a brick with a metallic U-shaped insert 8 having wings 13 and corresponding recesses 14 co-operating with the refractory, the recess 32 enabling the bricks to be suspended in pairs from an inverted T-shaped hanger. Part of a furnace arch showing this construction is seen in Fig. 14, hangers 46 being suspended from bars 48 in hooks 50 attached to overhead girders 49. The inserts may be offset in the bricks enabling a curved arch to be advantageously constructed, Fig. 12 (not shown), and said inserts may be of a variety of shapes e.g. Y-shaped. Specifications 600,649 and 600,650 show the walls and roof of an open hearth furnace uptake and a suspended furnace roof respectively, constructed according to this invention. The bricks are moulded (see Group V) under a pressure of 1,500-10,000 pounds per square inch and a suitable mixture is:- Chrome ore 6 x 28 mesh ...... 60% Dead-burnt Magnesite 50 mesh 40% or Chrome ore (coarse grains) 6 x 28 mesh ........................ 60% Magnesia (Periclose)fine grains 65 mesh ........................ 40% To both these mixtures a binder of 2 per .cent air floated kaolin and a solution of sulphuric acid to give a total content of 4 per cent water and 1 per cent acid is added.

Class 120(i) A machine for decorticating sisal and other fibrous leaves and of the kind wherein the leaves are passed through two rotary beater mechanisms by means of ropes or bands for decortication of two portions of the leaves successively has the beater mechanisms disposed about a driven vertical shaft which carries two pulley wheels driving the ropes and arranged so that the leaves will be gripped against one pulley while a portion is being treated and against the other pulley when the other portion is treated. Leaves are placed by manual or mechanical means on a feed conveyer 31 from which they are picked up by an intake rope 32 and a feed rope 38 and carried in a vertical position to a decorticating drum 12 operating in association with a stationary member 16. From this first decorticating point, the leaves are passed round an upper rope wheel 27 and a co-axial rope wheel 28 (not shown) against which the decorticated parts of the leaves are gripped by an output rope 42 and carried between a second decorticating drum 17 and stationary member 21, then onwards to a delivery point. The ropes 32, 38, 42 are driven by wheels 27 and 28 (not shown) on the vertical shaft 26 actuated by an electric motor located above the machine and connected through a manually operated clutch. The drums 12, 17 are driven directly from the motors through belts or chains. Rope 38 transmits drive to the conveyer 31.

Inventor: WOODHEAD ROBERT HARRY
IPC: D01G27/00
Filed: 1958-05-21
Abstract: 861,340. Lap winding apparatus. T. M. M. (RESEARCH) Ltd. Aug. 13, 1959 [May 21, 1958], No. 16361/58. Class 120(1) A lap winding machine of the type in which a fibre fleece is wound on a mandrel carried in the heads of braked racks has means for accelerating the lap driving rollers to sever the lap and to maintain the increased speed until an empty mandrel is brought into contact with the fleece on the lap driving rollers. When the lap has attained the desired size as measured by rotation of a disc 19, Fig. 1, a motor that drives the lap driving rollers 16, 17 at an increased speed is started, breaking the fleece. At the same time, the brake which retards the upward movements of the racks is released by operation of an hydraulic cylinder 41 and a rack motor 18 is started to drive the racks upwardly through gearing 181, 183, shaft 184 and rack pinions 141. The racks 14 continue to ascend after ejection of the lap and operate a mechanism for applying an empty mandrel to the rollers 16, 17, whereupon the rack motor 18 is reversed and the speed of rollers 16, 17 reduced to normal. The empty mandrel is disengaged from holders 72, Fig. 3, by loading hooks 67 carried on the upper ends of racks 14 and which are operated by cams 71. Also carried on racks 14 are arms 69 carrying a threader 68 which is allowed to swing downwardly and rearwardly when the mandrel is laid on the fleece in order to carry the end of the fleece over the mandrel to initiate the lap-winding operation. Mechanism is provided for stopping delivery of the fleece and to prevent normal doffing in the event of an electrical fault disabling the switch 46 that controls the rack motor 18. If there is not an empty mandrel in the holders 72 or if the completed lap has not been removed from the cradle 74, the machine will stop when the lap is full.

Detailed information is given concerning plant dimensions and liquor flow rates. In Fig. 3 waste water, oxygen and recycled sludge are fed to first oxygenation zone 25 then to central second oxygenation zone 37 whence the liquor radially traverses settling zone 45. Liquor passes from zone 25 to zone 37 via a vertical slot in the lower part of the dividing wall; and from zone 37 to zone 45 via a narrow gap at the bottom of the dividing wall with vertical projections from the floor spaced on each side thereof. Sludge is removed from zone 45 by pick-up heads suspended from movable bridge 52, and is partly recycled to zone 25 and partly fed via trough 51 to aerobic digestion zone 53 into which mixers are suspended from bridges 59. Clarified liquor zone 45 passes over wire 67 into trough 68 and thence to chlorination zone 61 from which it is finally discharged. In Fig. 2 (not shown), the chlorination zone 61 and bridges 59 of Fig. 3 are absent. In Fig. 8 (not shown) the entire annulus is comprised by the settling and first oxygenation zones only, and the centre by the second oxygenation zone. In Fig. 9 (not shown) the annulus is comprised by the settling zone, a sludge digestion zone, and three oxygenation zones, and the centre by the final oxygenation zone. In Fig. 10 (not shown) the annulus is comprised by the settling zone, two oxygenation zones and a chlorination zone and the centre by an aerobic sludge digestion zone.
