Abstract: 1330894 Repairing and making furnace linings GLAVERBEL 26 Oct 1970 [4 Nov 1969] 50836/70 Heading F4B [Also in Divisions B2 and C1] Solid particles of at least one oxidizable substance of size less 50 microns and particles of at least one other substance are projected against a surface so that as the oxidizable substance burns a coherent refractory mass is formed against the surface. The process may be used to repair furnace linings or roofs, or to coat refractory blocks, or, by allowing the molten mass to drip from a refractory plate, to form refractory blocks. The oxidizable solid particles comprise one or more of silicon, aluminium, magnesium or zirconium, and the other substance a compound of at least one of the above metals and oxygen, Silicon particles may be burnt in a jet of sand to give a silica coating; alumina and aluminium may be used to repair an alumina furnace lining; zircon, silicon and aluminium are used with zirconia and alumina to form a refractory coating; aluminium is used with zirconia and alumina; with magnesia and alumina; or with magnesia alone. The specification gives details of particle sizes and proportions of the different constituents. The material is projectd by apparatus comprising a hopper 31 within a chamber 7 to which oxygen or an oxidizing gas is supplied, the material being fed to a feed line 19 by a rotating disc 38 and scraper 44, and being entrained by the gas to a water cooled lance 6. A graphite disc 56 bursts on excess of pressure within chamber 7, a low temperature fuse 60 blows if combustion should start in the conduit 16, and a bimetal strip 62 is sensitive to the temperature of the coolant. A control system 80, linked also to a gauge 82 sensitive to pressure in the lance 6, operates to close the oxygen supply valve 68 and open a valve controlling a supply of flushing nitrogen, and to stop the drive of the disc 38, in case of malfunction.

Abstract: 1491036 Discharging centrifuges WESTFALIA SEPARATOR AG 25 Nov 1974 [21 Dec 1973] 51028/74 Heading B2P In a centrifuge for separating a mixture of solids and two liquids and comprising a self-emptying separator drum 1 from which the heavier of the separated liquids is discharged through a conduit 11, associated with a paring disc 10, or hermetically connected to the drum, in order to expel the lighter liquid from the drum before solids discharge orifices 16 in its outer peripheral wall 17 are opened, a valve 21 is incorporated in the heavy liquid discharge conduit 11 and is switchable by a control device 18 from an open discharge position to a throttled position, or to a completely shut off position, and is held in this latter position, until the heavy liquid in the drum has shifted the heavy liquid-light liquid interface 3 to the inner free liquid level 4 of the lighter liquid, after which the control device 18 cuts off the feed 24 of the mixture (introduced through a conduit 2) or of an auxiliary displacement liquid (supplied through a conduit 22) and opens a valve 20 incorporated in a conduit 14 for fluid controlling the operation of a sliding piston 13 so as to open the orifices 16 to effect discharge of the solids. During centrifugation, the lighter liquid is discharged, as shown, freely through radial openings 5 and the heavier liquid flows through an annular channel 6 between the drum cover 7 and a separator plate 8 to a paring chamber 9 from which it is discharged by the paring disc 10 through the conduit 11. The control device 18 controls the operation of valve 19 in the mixture supply conduit 2, of valve 20 in the control fluid conduit 14 and of valve 21 in the heavier liquid discharge conduit 11. When the chamber 12 of the drum is full of separated solids, the control device 18 first throttles or closes valve 21 so that the heavier liquid in the mixture rapidly shifts the interface 3 to position 4 thereby forcing the whole of the lighter liquid out of the drum through the openings 5. The control device then closes valve 19 and at the same time opens valve 20 to admit control fluid to a chamber 15 to cause the piston 13 to open the orifices 16 for discharging the solids. If, instead of the heavier liquid, an auxiliary liquid is used as displacement liquid to shift the interface 3, the control device closes valve 19 and opens valve 23 before, or at the same time as, it throttles or closes valve 21.

Abstract: 1,125,092. Feeding webs. WITTON - JAMES Ltd. 15 March, 1967 [17 Dec., 1965], No. 53632/65. Heading B6B. Web-roll changing apparatus of the type which includes a rotatable spider 2 and wherein the replacement web-roll 6 is accelerated up to speed before splicing, is characterized in that the old running web 7 passes over a backing bar 9 which is accurately positioned with respect to web severing means 18, and in that severing is controlled in dependence upon the angular position of the leading edge of replacement web and prior to the operation of the splicing means 15. This apparatus is capable of butt-splicing. Two backing bars 9 and 11 are rotatably mounted on the spider shaft 1 and are rotated by the frictional contact between the spider 2 and the collar 14. Final positioning of the backing bars against a retractable stop 17 is achieved with a pneumatically operated ratchet assembly 16 which overcomes this frictional contact. The severing means 18 comprises a cutting cylinder 19 rotatably mounted between two support members 20 slidably mounted in guides 22. The guides 22 are inclined towards the retractable stop 17, so that when the V-shaped notches 21 engage the backing bar 9 or 11, the bar is rigidly held against the stop 17. The cutting cylinder 19 comprises a circular shaft having a radially extending knife and the backing bars 9 and 11 are made of, or are each provided with an insert of resilient material against which the knife acts. Alternatively, the cutting cylinder 19 has a knife arranged to co-operate with a knife provided on each backing bar. The control means for the apparatus comprises a first generator which gives signals dependent upon the linear speed of the old running web; a second generator which gives signals dependent upon the peripheral speed of the replacement web-roll; a frequency comparator responsive to both sets of signals and designed to maintain the replacement web-roll at the correct speed; a detector responsive to the passage of a reference element rotating with the replacement web-roll and positioned with respect to the leading edge of the replacement web, which detector generates a reference signal when the replacement webroll is rotating at the correct speed; and a trigger circuit responsive to the reference signal and designed to initiate the operation of the severing means and web contacting means in a selected time relationship.
