Abstract: 839,485. Cables; cable joints. BRITISH INSULATED CALLENDER'S CABLES Ltd. May 23, 1958 [May 24, 1957], No. 16606/57. Drawings to Specification. Classes 36 and 38 (1). A high-voltage cable or cable joint is made by applying to a conductor or jointed conductor a plurality of helically lapped tapes of highenergy-irradiated polyethylene having a soluble fraction of from 15-40 %, heating the insulated conductor under vacuum to 15-60 ‹C. to remove entrained air and thereafter heating to 135-150‹ C. under vacuum to cause the tapes to shrink and weld together and the residual cavities to be filled with temporarily liquid polyethylene pressed out of the tapes by their shrinkage. The irradiated polyethylene tape used should be such that a substantial proportion, preferably a greater proportion, of the molecules aie oriented in a direction longitudinally of the tape. The tape should preferably be provided with corrugations, pimples or grooves on at least one side to facilitate air extraction. Prior to the lapping with the irradiated polyethylene tape, the conductor is provided with a conductive surface of metal, metallized paper or, preferably, unirradiated conductive polyethylene. During the high temperature heat treatment a temperature gradient is established in the dielectric wall e.g. by passing a heavy current through the conductor. A stress control layer may be provided around the heat-treated dielectric layer by lapping it with irradiated conductive polyethylene tape under tension and repeating the heat treatment.

Title: Improvements in or relating to control systems for electric motors
IPC: H02P1/20
Filed: 1932-06-15
Abstract: 403,433. Master control of motors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Schaelchlin, W. ; 169, Woodside Road, Wilkinsburg, Pennsylvania, U.S.A.) June 15, 1932, No. 16919. Convention date, June 27, 1931. [Class 38 (iii).] The starting resistor sections 4 are shortcircuited sequentially by contactors which have a time-delay in closing upon de-energization of their operating-coils. Closure of " start " button 11 causes opening of contactor 7 which at contacts 28 causes opening of contactor 8. In turn contactor 8 causes at contacts 32 opening of contactor 9, which at contacts 37 causes closure of line contactor 5. The latter maintains itself at contacts 41 over " stop " button 34 and contacts of overload relay 6, and de-energizes the operating-coil of contactor 7 by opening contacts 15. Contactor 7 gradually falls to its closed position under the retardation of a constantly neutralizing coil 18. When it reaches its closed position it de-energizes the operating-coil of contactor 8, and thus the closing operation of the contactors proceeds with a time delay between each.

Abstract: 505,463. Toasting-apparatus. MELBA MACHINERY ROYALTY CORPORATION. June 8, 1938, No. 17035. Convention date, May 10. [Class 28 (i)] In a toasting-machine, the slices are held between toast. ing-plates, hinged together in pairs 30, 34 that they may be separated for removal and insertion of slices, the plates 30 being pivoted together, in series, to form an endless conveyer. The pivot shafts 31 pass through eyes 32 on the ends of bars 33 which are secured to the opposite side edges of the plates 30. The plates 34 are pivoted to the shafts 31 by bars 36 secured to the sides of the plates and having eyes 35 embracing the shafts 31, retaining collars 37 being provided. The shafts 31 carry grooved rollers 38 which engage guide tracks 21, 22, the upper and lower runs of the conveyer being thereby kept straight. The conveyer is driven by the engagement of reduced ends 39 of the shafts 31 between adjacent teeth of sprocket wheels 19, 20, alignment of the ends 39 with the teeth being ensured by end plates 40. The opening and closing of the plates 34 is effected by rollers 42, on the ends of square-sectioned bars 41 secured to the backs of the plates, engaging cam tracks 24, 25. The tracks 25 are joined with lower tracks 23 by tracks 26. At the end of the tracks 23, the plates 34 are allowed to swing open, to an extent limited by guides 23a, the toasted slices falling into a hopper 47 from which they are removed by conveyer 4S. The rollers 42 are transferred to the upper sides of the tracks 24 by means comprising a lever 51 pivoted at 52 and urged by a spring 55 against a stop 56, in which position the nose 57 lies in the path of the rollers 38. The rollers thus lift the nose 57 and a lateral pin 58 on the lever 51 engages the corresponding roller 42 and moves the plate 34 outwardly until the rollers 42 engage the flared ends of the tracks 24. The nose 57 then trips over the roller 38 and returns to be engaged by the next roller The ends of the tracks 24 are secured by braces 61. The plates are heated by upper and lower gas pipes 49, 50, and the drive is effected through gearing by a motor M. The plates 34 have adjustable studs 43 which determine the width of the space between the plates 30, 34.

Title: Improvements in electrically operated speed regulators
IPC: F02D1/08
Filed: 1920-06-23
Abstract: Hexamethylenetetramine is prepared by oxidizing methane with air or oxygen in the presence of ammonia gas.  The mixture of methane, oxygen or air, and ammonia gas in combining proportions may be passed through an isoprene lamp or through a constricted metallic tube which is heated at the constricted part.  After condensing the products, the gases may again be led through the apparatus.  The tube is made of such a metal as copper, silver, nickel steel, iron, or alloys of iron with tin, zinc, aluminium, or silicon, or of iron with a coating of one of these metals.  The tube then acts as a catalyst; but contact material in the form of thin wire or sheets of silver, copper, nickel, or alloys thereof, may be introduced with an iron or steel tube.  The reaction may take place under reduced pressure, and the methane may be replaced by natural gas.  By reducing the amount of ammonia in the gas mixture to be treated, the product is richer in formaldehyde.  The hexamethylenetetramine obtained can be converted into formaldehyde.

Title: Improvements in devices for sandpapering or polishing floors and like surfaces
IPC: A47L11/18
Filed: 1919-07-08
Abstract: 144,123. Clarke, A. A. July 8, 1919. Floors and like surfaces, treating.-Relates to apparatus of the kind in which the surfacetreating member is propelled by an electric or other motor, and consists of means for adjusting the polishing or like member vertically with respect to the surface to be treated. As shown in Fig. 1, the surfacing- material 2 is mounted on a self-contained motordriven drum 1, the armature of which is supported by the side plates 3 of a frame carried on standards 4. The height of the polisher 2 above the work is adjusted by rotating a handle 5, which, by means of a sprocket chain 7, rotates sprocketwheels 8<1> mounted on screw-threaded posts 9 extending through the standards, thereby raising or lowering the frame carrying the drum. Alternatively, the polishing-drum 30, Fig. 2, may be carried in a subframe 33 which is raised or lowered relatively to the main frame 34 resting on runners 48, by similar chain and sprocket gear 40, 41, 43 operated through a thumb-button 47 to rotate screwed spindles 39 mounted on the frame 34 and engaging with lugs 37 carried by the sub-frame 33. In the form shown in Fig. 6, a polishing or like belt 70 driven by an armature drum 65 passes over a roller 68, being tensioned by a spring-pressed roller 71. To hold the belt in contact with the work, a flexible metal plate 83 is secured at one end to a fixed bracket 84 and is fastened at the other end to a yoke 85 pivoted on the shaft of the roller 68. By turning the handle 88, an eccentric link 86 swings the yoke 85 about its pivot and forces the belt into close contact with the work. The whole frame is raised or lowered relatively to the work by means of the handle 64, which, through a spiral gearwheel 62, actuates the sprocket chain 57 and rotates gears mounted on screwed spindles .53 passing through standards 51. A plunger 82 is depressed from time to time by hand to actuate a spring-controlled lever 81 which opens the valves of reservoirs containing surfacing or polishing material to be fed on to the belt. In a further modification, the polishing-drum is driven by toothed gearing from the motor. A long handle may be fitted to any of the machines when used for treating floors, and the height-adjusting mechanism may then be actuated through a flexible shaft with a terminal turn-button mounted convenient to the operating-handle of the machine.
