Abstract: 367,568. Roller bearings. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (American Steel Foundries; 410, North Michigan Avenue, Chicago, U.S.A.) Feb. 23, 1931, No. 5683. [Classes 12 (i) and 12 (ii).] A vehicle wheel and axle assembly comprises. a revoluble axle, a substantially non-rotatable axle, and roller bearings therebetween, one of the race rings having a thrust surface engaging a similar surface on the rollers and the other race ring having a convex race track permitting deflection of the non-rotatable. axle. The rotatable axle 24, Fig. 1, has flared ends 22 forming lubricant reservoirs to which lubricant is supplied through passages 16, 20 in the non- rotatable axle 10. The bearing cone 38 is pressed on the axle 10 and maintained thereon by a shrunk collar 40. The conical rollers 44 have a portion 46 contacting a thrust rib 50 on the cup 42 and make line contact with the cup. The race track on the cone 38 is longitudinally slightly convex to permit deflection of the axle 10. A cover-plate 66 secured to the axle 24 has an oil groove 60 and a flange 72 fitting between a baffle ring 74 on the collar 40 and a shoulder 76 on the cone 38. The roller spacing cage 56 frictionally engages the inner wall of the groove 60 and is rotated thereby. The cover 66 is of uniform thickness to avoid cracks when casting. The race track on the cone may contact the rollers only at one end or it may have line contact with the rollers for a part of their length, the remaining surface being curved convexly. The spacing cage 56 may frictionally engage an annular plate perforated to permit the passage of lubricant and clamped between the cover and the cup, or it may have an annular flange portion extending between a groove formed between the cover and cup. In the latter case a lubricant deflecting plate overlying the channel 60 is fitted in the groove 54. In the construction shown in Fig. 10 the cone 148 has a spherical race track 150 and the race track on the cup 156 is convex. The rollers are smaller at the inner ends so that lines 162, 164 drawn through the end edges meet at a point on the bearing axis. The rollers have a conical end engaging a flange 168 separate or integral with the cup 156. As shown the flange 168 is secured to the cup 156 by a flanged sleeve 170. The roller cage 172 is guided by an extension fitting closely over a flange 176 on the cover 178 and by an inner annular ring portion extending close to the cone 148. In another modification the cover-plate is integral with the sleeve 170 and to it are bolted plate members which co-operate with the parts such as 74, 76, Fig. 1, to exclude foreign matter and which pump lubricant towards the bearing during operation.

Title: A process for preparing viscous oils, such as lubricating oils, transformer oils andthe like
IPC: C10G50/00
Filed: 1938-02-25
Abstract: In preparing viscous oils, such as lubricating and transformer oils by polymerization of cracked distillates in the presence of metal halides, separating the sludge and concentrating the product by distilling off the light oils, the polymerized reaction products, before concentration, are heated in the presence of adsorptive earths or other surface agents, preferably while introducing steam, to temperatures of 200 to 300 DEG  C., while discharging or binding the hydrogen halide formed.  The polymerization products are then separated from the solid substances and concentrated to viscous form by distilling off the lighter constituents.  In the example, a vapour phase cracked distillate of paraffinous base material is polymerized by heating to 100 DEG  C. in the presence of about 4 per cent of AlCl3 followed by separation of the sludge.  The polymerizate is neutralized by caustic soda lye and then stirred with activated bleaching earth by a continuous feed apparatus.  The mixture discharged from the bottom is heated to 220 DEG  C. in a vessel in which steam is fed to the bottom.  At the top of the vessel, steam and most of the volatile constituents, together with the separated HCl, escape.  At the bottom, the treated polymerization product is continuously discharged and is concentrated to required viscosity by vacuum distillation.  The oil is practically free from chlorine. Specification 398,032 is referred to.ALSO:In preparing viscous hydrocarbon oils by polymerization of cracked distillates in the presence of metal halides, separating the sludge and concentrating by distilling off the light oils, the polymerized reaction products, before concentration, are heated in the presence of adsorptive earths or other surface agents, preferably while introducing steam, to temperatures of 200-300 DEG  C., while discharging or binding the hydrogen halide formed.

Title: Means for preheating liquid fuel
Inventor: EVANS WILLIAM BASIL
IPC: F23K5/20
Filed: 1963-02-15
Abstract: 997,022. Preheating liquid fuel. MIDLAND COMBUSTION Ltd. Feb. 5, 1964 [Feb. 5, 1963; Sept. 26, 1963], Nos. 6189/63 and 38012/63. Heading F4S. In a system for supplying preheated liquid fuel from a reservoir to a burner ring main, the fuel is heated in a vessel 6 by steam tubes 10, electric elements 9a being provided in the vessel 6 for use before the steam supply becomes available, i.e. when the system is starting up. The vessel 6 is connected to the fuel reservoir (not shown), through another vessel 5 to which it is welded. When in operation fuel is drawn by pumps 13 into the vessel 5 from the fuel reservoir, and passes thence through tubes 11 and 12, pumps 13, and pipes 15 and 16 to the inlet 17 of vessel 6. Heated fuel passes from the vessel 6 through tube 18 leading to the outlet tube 19. From the tube 19 the fuel passes through the burner ring main system (not shown), from which the excess fuel is returned for reheating via connection 12a to the heater. Fuel leaving the heater through tube 18 may be recirculated if necessary to the vessel 5 through a pipe 21 containing a thermally sensitive valve (not shown). Sufficient heat in vessel 5 cannot be maintained merely by conduction from the vessel 6 when the burners, to which the fuel is fed, are working and a supplementary heating device may be mounted in vessel 5 at 24. Alternatively a quantity of warm fuel from the vessel 6 or from the return flow may be recirculated through the vessel 5. A supplementary reservoir having its own heater may be provided (Fig. 4, not shown).

Title: Improvements in detergents
IPC: C01B33/46
Filed: 1939-02-25
Abstract: 525,514. Detergents. LAPORTE, Ltd., B., and WEBER, I. E. Feb. 25, 1939, No. 6282. [Class 91] An alkaline detergent composition is prepared by heating a mixture of sodium carbonate and silica in a proportion within the limits of 2.5 mols. to 4 mols. of sodium carbonate to 1 mol. of silica to, or above the temperature of incipient fusion of the mixture. The sodium carbonate may be formed from an equivalent amount of sodium bicarbonate in the presence of the silica during the process. It is stated that the pH of compositions prepared from the ingredients in the proportion named above is substantially the same as that of a composition prepared from two molecules of sodium carbonate to one mol. of silica, but the composition possesses the advantage of a lower melting point. In examples (1) a mixture of 600 parts of silica sand and 3,900 parts of sodium carbonate is fed continuously into a furnace at 1,000‹C., and the molten product is allowed to flow from the furnace as it fuses. (2) 600 grams of silica sand are mixed with 2,900 grams of sodium carbonate and the mixture heated to incipient fusion at about 900‹C. The detergent composition of the invention may be used alone or in admixture with other substances such as soap, phosphates, meta-phosphates, pyrophosphates, substances having an oxidizing or a reducing action, resinates and sulphonated fatty alcohols.

Filed: 1966-02-12
Abstract: 1,156,659. Automatic thickness control. DAVY & UNITED ENG. CO. Ltd. and R. B. SIMS. Feb. 10, 1967 [Feb. 12, 1966], No.6313/66. Heading G3R. In an error-actuated thickness control system for rolled material, the error controls the tension in material entering or leaving the rolls if the error is small, and the setting of a hydraulicallyoperated roll gap adjuster if the error exceeds a predetermined value. As shown, metal strip 21 passes through rolls 17 to a coiler 23. Tension in the strip leaving the rolls is stabilized by applying the output of a loop tension detector 22A to a voltage controller 37 which varies the speed of a motor 24 driving coiler 23. A detector 22, e.g. of the X-ray type, produces a signal, corresponding to the thickness of the strip leaving the rolls, which is compared at 30 with a signal from a unit 31 representing a desired thickness. Any difference, representing thickness error, is applied through a switch A1, normally positioned as shown, to position a servo-operated potentiometer 35 the output of which varies the datum of the tension control system at 36 to correct the thickness error. The output of popentiometer 35 is also compared at 38 with a predetermined value from a unit 40 so that, when the error is excessive, a relay A is operated and contacts A1 change over. A servo-operated potentiometer 28 is then positioned to correct the thickness error by varying the datum of a fluid pressure control system, including a detector 27 and a valve corrector 26, which normally stabilizes the hydraulic pressure applied to cylinders 6 bearing against back-up rolls 1 to determine the roll gap. Under these conditions contact A2 of relay A causes motor 33 to reset potentiometer 35 to its central position to restore tension to an intermediate value, whereupon relay A, which only reverts to its normal position when the signal from potentiometer 35 is zero, restores contacts A 1 , A 2  to the positions shown. Control of tension of the strip entering the mill, indirect measurement of thickness, and application to the control of multi-stand mills are referred to.
