Filed: 1952-05-16
Abstract: 738,163. Grinding-mills. EDWARDS, J. N. May 16, 1952 [March 28, 1952], No. 12455/52. Class 59. [Also in Groups XXVI, XXIX and XXXIV] A ram cap for the movable bearing 14 of a crushing or pressing roll 12 in a grinding mill comprises a cylinder 16, a piston 17, a plunger 18 connected to the piston and a peripheral packing-ring 39 on the piston at the end thereof adjacent the plunger so that the pressure liquid acting on the piston has access to the major portion of its peripheral surface. Pressure liquid having lubricating qualities is forced into a cylinder 16 for the bearing 14 at each end of the roll 12 preferably from accumulators 34 which, as described in Specification 678,053, have a liquid compartment bounded by the flexible wall 34a of a compartment containing gas under pressure. The liquid enters the cylinders through tubes 35 which are screwed into the cylinder heads 20 or attached by a nut on the inside of the cylinder. A liner 19, preferably of steel and having a ground, chromium plated bore, is a sliding fit in the cylinder and is secured in place by the head 20 which has flanges 22 having a bayonet-engagement with the sloping undersurfaces of flanges 23 on the cylinder. Alternatively, the head may engage screw-threads in the cylinder and be formed with an integral extension 21, provided with a gasket 24 and a supporting ring 25 of rubber, instead of an extension 21 attached by bolts. In order to facilitate other than parallel movements of the roll 12, the plungers 18 are arranged to engage the bearings 14 through a concave surface on a member 28, Fig. 5, and a convex surface on a pad 15. The position of the roll 12 may be indicated on scales 32 by floats 33 in chambers 31 supplied with lubricating oil from beneath the pistons. The float may be arranged to rotate a pointer 49, Fig. 7. The packing ring 39 of resilient material may be supported by one or a pair of leather washers 38, and a ring of oiled felt 41 is located beneath the packing ring. A plurality of annular grooves 37a distribute the lubricant from the top of the cylinder. In various modifications, the piston may have a plurality of axial grooves to connect the circumferential grooves, a single axial passage down the centre of the piston and connected by radial passages to the circumferential grooves, or a circumferential groove of helical form.

Title: Process and Device for Increasing the Uniformity of Filaments.
Inventor: BEYREUTHER ROLAND
IPC: D01D13/00
Filed: 1968-03-14
Abstract: 1,165,645. Filament uniformity; measuring. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. 14 March, 1968, No. 12507/68. Heading D1F. In a process for increasing the uniformity of textile filaments, a focussed air current is directed onto a filament emerging from a supply source and is divided by the filament, the residual intensity of the air current being subsequently measured, the measured value obtained being converted into a control signal by a regulator, which signal is used for adjusting the parameters governing the fineness of the filament. Apparatus for carrying out the method comprises a pressurised air source 1 connected to a nozzle 2 which is positioned relative to a filament path through guides 14 such that the air current from the nozzle 2 will be divided by the filament 4 and partially impinge upon an opening 7 in a pneumatic receiver 8, the receiver 8 being in turn connected to a regulator 9 which converts the measured value obtained from receiver 8 into a control signal. The control signal may be used to control the speed of a take-up spool 13 or the feed of the filament from a supply source 5. The boundary layer of air associated with a fast running filament may be reduced by means of an air nozzle 19 positioned upstream of the nozzle 2. The receiver 8 may also be connected to an indicating or registering instrument which in turn may be connected to a statistical analyzer. The receiver 8 preferably comprises a membrane 15 and variable electrical resistances 16 connected therewith. The nozzle 2 may be positioned at an angle to the filament path.

Title: Process and apparatus for extracting organic matter from inorganic-bituminous deposits
IPC: C10C3/00
Filed: 1975-03-25
Abstract: 1519981 Extraction apparatus P KRAEMER and O MERESZ 12 March 1976 [25 March 1975] 12518/75 Heading B1Q [Also in Division C5] Organic bituminous components are separated from tar sand or oil shale by conveying the sand or shale along an upwardly inclined path with tumbling agitation whilst a solvent for the organic components passes downwardly through the zone. Suitable solvents are naphtha, kerosine and dichloroethylene. Sand or shale is crushed and mixed with solvent in a hopper 23 and fed into a lower portion of a washing zone 21. As the zone 21 is rotated, the sand or shale is tumbled and moved towards the upper end of the zone 21 by a helical conveyor 22. Solvent is passed into the upper end of the zone 21 and flows downwardly, passing through apertures at the outer edges of the helix 22. A scoop 22 removes solids from the solution in a lower compartment and the solution is pumped from the lowermost compartment 15. The washed solids leave the upper end of the zone 21 and pass into a solvent recovery system comprising a vibrating zone 37, a zone 56 heated by a jacket 58 to drive solvent vapours from the solids, and a cooling zone 57 prior to discharge. The vapour spaces in the heating zone 56 and the cooling zone 57 are separated by a cylindrical formation 85 attached to the helix and an accumulation of solids, caused by a portion of the helix where the flights are only half the pitch of those lower down, so that solvent vapours from the heating zone 56 pass to the washing zone 21 where they condense. Figs. 1, 4, and 5 (not shown) illustrate an alternative embodiment in which the solvent vapours are condensed within the heating and cooling zones and returned to the washing zone by a pipe.

Filed: 1969-03-11
Abstract: 1,222,305. Vehicle suspensions and wheels. W. W. CUSHMAN. 11 March, 1969, No. 12834/69. Headings B7C, B7D and B7H. A load bearing arrangement for a vehicle in which a pair of hubless rollers 26 or 60 are interconnected by an endless belt or chain 40 or 72 has a load carrying roller 22 or 62 supported on the upper run of the belt or chain 40 or 72 between the two rollers 26 or 60 so that the load supported on a bracket 14, 18 attached to the shaft 20 or 58 of the load carrying roller 22 or 62 imposes a radially compressive force around the majority of the circumference of the two rollers 26 or 60. The rollers 26 or 60 may be in direct contact with the surface over which the vehicle is intended to traverse or the rollers may be covered with an endless belt 76, as shown in Fig. 6, which is in contact with the surface, but in either case additional snubber belts 44 or 74 are provided to restrain the relative movement and positions of the rollers, the snubber belts being in the form of resilient material which permits twisting of the rollers relative to each other. The belt or chain and snubber belts are carried in grooves in the rollers and the latter take an opposite path over the load bearing roller 22, 58 to that followed by the belt or chain 40 or 72. As shown in Fig. 2, the chain and snubber belts are supported in grooves in a recessed portion of the rollers 26 and this recessed portion may be covered by an endless belt. The arrangement may be applied to a vehicle which is to be moved such that the rollers roll freely over the surface to be traversed or within the endless belt covering the rollers and contacting the surface. Alternatively the load bearing roller may be positively driven from the vehicle drive. Additional tensioning rollers may be provided to engage the snubber belts to keep them taut. The rollers may be rigid or may be formed from thin steel material suitably corrugated to permit the actual rollers to be flexible such that their surfaces more readily follow the contour of the terrain. The drive to the rollers may be through a differential and a flexible shaft, the rollers being mounted on the end of the shaft and capable of relative angular movement enabling the whole unit to pivot transversely in one direction or the other. The surrounding endless belt may take various forms and have flexible side walls which cover the ends of the rollers and are sealed about the shaft supporting the load bearing rollers to prevent the ingress of dirt. Additionally the unit may be sealed or the rollers may be sealed at their ends to render the unit buoyant, or to enable the rollers to be filled with ballast to increase their weight.

Abstract: 5 9 2 , 1 5 4 . Centrifugal separators. LOUMIET, J. P. May 23, 1945, No. 12867. Convention date, May 25, 1944. [Class 23] The separator, of the type described in Specification 447,457, is cylindrical-shaped, having an inner member forming a spiral path for the fluid mixture with a varying cross-section to cause accelerations and decelerations of the mixture. In Fig. 1, the separator has slots D‹ and G, near the narrowest crosssections of the path formed between cylinders D and E, for the removal of a heavy fluid, such as oil from steam. The mixture enters a port A, and the lighter fluid, e.g. steam, leaves through an outlet B. The wall surface of the cylinder E may be lined with felt, and wire mesh J may be arranged over the extraction openings E<SP>111</SP> to prevent re-bounding of the oil globules hurled against the casing. The wires of the mesh J are preferably of triangular cross-section with one of their apices directed radially inwards. Fig. 4 shows a modification with perforated metal or wire-cloth K arranged to form a trap over each outlet E<SP>111</SP>. Felt may be provided on the casing E inside the cloth K. In place of the wire-cloth, a series of inclined planes formed in Venetian-blind fashion may be placed adjacent the outlets E<SP>111</SP>. A further modification, Fig. 7, includes two cones C<SP>1</SP>, C<SP>2</SP> concentrically arranged in a casing E, the spiral coil containing an extraction channel D <SP>1</SP> in its outer periphery leading to a drain G<SP>1</SP>. A modified vertical separator has the variations in cross-section of the mixture path, produced by deviations in the pitch of the spiral coil, which alternately increases and decreases. Grooves are provided to collect the oil particles. In a final arrangement, the outer casing E is made of sheet metal in part joined to a casting in which the outlet channels for the oil are placed. The cast metal is of material which will not cause excessive rebounding of the oil particles.

Abstract: 671,391. Blast-furnace hearths. CARBLOX, Ltd. May 9,1950 [May 13, 1949], No. 12867/49. Class 51 (ii). A carbon block for use in the construction of blast furnace hearths and formed so as to interlock with another like block, has four plane faces and corrugations on two opposite sides only, and the top of the ridges and the bottoms of the grooves of the corrugations are so formed that when the block is engaged with another like block the ridges seat upon a substantial area of the bottom of the grooves. A rectangular carbon block, Fig. 1, has four plane faces, and corrugations formed on two opposite sides. The corrugations on one face of the block are opposite to the grooves between the corrugations on the opposite side, and are so formed that there is a substantial seating area between the corrugations of one block and the grooves of an adjacent block. The tops of the corrugations and the bottom of the grooves are flat, and the grooves are wider than the corrugations. The sides of each corrugation slope outwardly towards the grooves on either side, and are curved to avoid corners. The size of the corrugations are such that there is half the width of a corrugation at each end of one face of a block and half the width of a groove at each end of the opposite face, while contraction of the blocks in use cannot cause complete disengagement of the corrugations and grooves. A blast furnace hearth, Figs. 2 and 3, is built of vertical columns of corrugated carbon blocks, with the corrugations running horizontally on vertical faces of the blocks and keying with the grooves in blocks of adjacent columns. Each column comprises blocks of two different sizes, and the blocks are staggered so that the horizontal and vertical joints between plane faces of the blocks are broken. The well wall of the hearth is formed of four rings of the uncorrugated carbon blocks, the inner rings 6, 7 surmounting the horizontal hearth formed of corrugated blocks, and the outer rings 4, 5 breaking the horizontal joint at hearth level. A carbon ramming material, which may contain a small amount of broken prefired brick, is tamped to high density between the outer well wall 5 and the furnace casing 8 as at 10 and between the horizontal hearth and the ring 4 of wall blocks as at 9. Corrugated blocks may be used right out to the outer furnace casing 8, or shaped blocks having only one corrugated face may be used in the peripheral portion of the corrugated block assembly.
