Filed: 1947-09-09
Abstract: 634,245. Grinding and polishing. BURGESS, A. F. (Paper Patents Co.). Sept. 9, 1947, No. 24756. [Class 60] Apparatus for grinding or polishing the surface of a cylinder comprises a form roll mounted to rotate upon an axis substantially parallel with the rotational axis of said cylinder, means for rotating said cylinder and said form roll, an endless abrasive belt interposed between said cylinder and said roll and having an abrasive surface operatively engaging said cylinder, and means for inducing said belt to move progressively along the form roll. The cylinder 10, such as the dryer of a paper machine, is rotated by a motor 15 through belt 15a, mitre gears 17, 18, worm gearing 19, 20 and pinions 22, 14, 13. The abrasive belt 38 passes round a form roll 26 and a tension roll 37, driven by belts 15b, 15c respectively from the motor 15. The two ends of the rolls 26, 37 are independently adjustable, and by making the distance between the rolls at one end different from that at the opposite end, the belt 38 is caused to creep along the rolls; alternatively, an additional guide roll 39 is provided which is inclined to the direction of travel of the belt 38, whereby the latter is caused to creep. For crowned rolls, the form roll 26 has a complementary shape; by inclining the form roll 26 relative to the cylinder, a modified shape is obtained on the cylinder. The apparatus is used for surfacing cylinders initially, or for re-surfacing worn cylinders in situ; steam may, during the operation, be supplied to the cylinder at the same pressure as when the cylinder is in use, so as to simulate working conditions.

Patent GB-834940-A (GB)
Title: Process for the removal of soot from suspensions thereof in water
IPC: F26B5/00
Filed: 1957-08-12
Abstract: Soot is removed from aqueous suspensions thereof containing up to 5% wt. of soot by contact with an aqueous emulsion of a water immiscible organic liquid which has a higher adhesion tension than water for soot, the resultant agglomerates of soot and organic liquid being separated from the aqueous phase.  Aqueous emulsions may be formed by the intense mixing of an aqueous phase with an immiscible organic liquid in proportion of 100 : 1 to 100 : 100 preferably 100 : 20 to 100 : 60, the organic liquid may be a hydrocarbon, e.g. pentane, hexane, heptane, benzene, toluene, light naphtha, or mixtures thereof, halogen-substituted hydrocarbons, e.g. CCl4, CHCl3, C2H2Cl2 or C2HCl3 or hydrocarbon oil distillates or residues, e.g. gasoline, kerosine, gas oil or residual fuel oils.  Improvement of the stability of such emulsions is obtained by either increasing the pH of the aqueous phase to about 9 or by the addition of specified surface-active agents.  Aqueous suspensions of soot are contacted with between 0.8 and 10 gms. of organic liquid in the form of an emulsion per gram of soot present.  Soot and organic liquid form agglomerates containing say 5% water, within a few seconds and are removed from the aqueous phase by screening, filtering or decantation.  Soot may be recovered by evaporation of the organic liquid on the pellets, especially when formed with a heavy hydrocarbon oil, e.g. gas oil may be mixed with a fuel oil and used as a fuel or reactant in the synthesis gas process.  Specification 327,979, 734,475, 741,135 and 826,209 are referred to.

Title: Improvements in or relating to engine starter drives for internal combustion engines
IPC: F02N15/04
Filed: 1959-07-23
Abstract: 865,557. Engine turning gear. PAPST, H. July 23, 1959, No. 25390/59. Class 7(5). In an engine starter drive for an engine having an associated starter motor/dynamo comprising a coupling nut operating in opposite directions for automatic change over from starter motor to dynamo operation, the coupling nut is provided with a radially expanding spring ring by which for starter motor operation it is caused to rotate on the screw thread and thus to exert pressure against a transmission disc, thereby coupling the disc to the engine, or when the engine is running is moved against a transmission disc connected to the motor/dynamo. When the engine is to be started the machine 2, serving as a starting motor, is energized and by way of the belt drive 3, 4, 5 and the gears 7b, 11 and 14 drives the member 6. The latter through the medium of the expanding ring 9 drives the coupling nut 8 which in consequence of its engagement with the thread 1c moves axially to the left and presses the member 6 against the flange 10. A friction coupling is thus produced between the member 6 and flange 10 and the crank-shaft 1 is set into rotation. On idling of the engine the coupling nut 8 retains the position shown. On acceleration the thread 1c causes the coupling nut 8 to be moved to the right so that the ring 9 and the coupling member 7 come into engagement by their conical surfaces. The crank-shaft then drives the machine 2 which then operates as a generator.
