Abstract: 951,020. Gas filters. FULLER CO. July 30, 1962 [Sept. 1, 1961], No. 29242/62. Heading BIT. A dust-laden gas filter comprises a casing 2 having an inlet 6 for unfiltered gas and outlets 7 for filtered gas and having filtering elements 8 disposed therein, and a casing 20 in which is a valve rotor 22, the casing 20 having ports 23 connected to the outlets 7 by ducts 24, a clean gas outlet 52 and ports 25 leading to the atmosphere, the valve rotor 22 having a chamber 28 through which communication may be established between any pair of ports 23 and 25 for reverse-flow cleaning of the filtering element associated with those ports. The casing 2 has an outlet 5 for the material filtered from the gas, the outlet being provided with a rotary feeder (not shown). The inlet 6 is tangential to the lower part of the casing 2 which is provided with a baffle skirt 9 so forming a primary separating chamber 11. The filtering elements comprise filter sleeves 18 of quilted material known by the Registered Trade Mark "Orlon'', or woven fabric, and cage screens 16. The chamber 28 is located at one side of the valve rotor 22 which is mounted on a shaft 41, the latter being driven through a chain drive by a geared motor (not shown), the motor being so connected electrically that at predetermined time intervals or at a time determined by the pressure differential across the filtering elements the valve rotor is rotated to clean each filtering element in turn, a limit switch being operated after a predetermined number of revolutions of the valve rotor to stop the motor so that the valve rotor will stop with the chamber 28 intermediate a pair of the ports 23 and 25. The chamber 28 communicates with each port 25 through spaced ports 35, 35a and 35b, Fig. 2 (not shown), so that as the valve rotor rotates each filtering element will be subject to separate pulses of cleaning air. The ports 25 communicate with the atmosphere through a manifold 36 and a valve controlled pipe 37. A cover-plate 21 of the casing 20 has a bleed port 45 therein providing limited, pressure-balancing communication between the interior of the valve rotor and the atmosphere to prevent pressure-extrusion of the grease in bearings 42, 43 of the shaft 41. The outlet 52 leads through a conduit 53 to an exhauster (not shown).

Title: Improvements in or relating to abrasive materials and methods of making them
IPC: C09K3/14
Filed: 1932-10-21
Abstract: Refractory or abrasive material is made by fusing together alumina and added material consisting of substantial proportions of silica and an oxide or oxides of calcium, magnesium, barium, sodium or potassium.  A fused magma is formed from which a crystalline structure of alumina or aluminous material develops within a matrix of more fusible material, which may be crystalline or not.  The composite material may be crushed to form self-bonding grains from which articles are formed by moulding and firing, but additional binding material may be used.  By regulating the proportions of silica and added oxide, a series of related abrasives may be made. In an example, a mixture of 70 parts of aluminous ore, 10 parts of lime of 20 parts of silica is fused in an electric furnace and cooled.  Alumina crystallizes out and the remainder solidifies to a glassy matrix.  Bauxite or clay may be used as the source of alumina, flint clay, or quartz sand for silica, unslaked lime or limestone for lime and magnesite for magnesia.  Examples illustrating the manufacture of abrasive wheels, (self bonded or with added bond), floor tile aggregates, floor tiles and refractory articles are described.  Specifications 324,312, [Class 22], and 343,896, [Group V], are referred to.ALSO:Refractory or abrasive material is made by fusing together alumina and added material consisting of substantial proportions of silica and an oxide or oxides of calcium, magnesium, barium, sodium or potassium.
