Abstract: 652,558. Transformers; supply systems for discharge apparatus. FERRANTI, Ltd., and GLOVER, A. J. Sept. 24, 1948. [Classes 38 (ii) and 38 (iv)] A moving coil voltage regulator of the autotransformer type having two primary windings 1, 2 in series and with considerable leakage reactance therebetween, auxiliary secondary windings 5, 6 and a movable shortcircuited winding 17, has tapping means 10 which in the " starting " position, i.e. with moving contact 7 on fixed contact 11, disconnects a portion 14 of the primary winding 1 from the secondary circuit and in the " running " position, i.e. with moving contact 7 on fixed contact 13, includes this portion in circuit, the tapping means being automatically changed over when the short-circuited winding attains close magnetic association with this portion at the end of the " starting " process, the tapping means being maintained in the " running " position during subsequent operation. The windings 5, 6 are respectively arranged as bucking and boosting windings and at starting the moving coil 17 is positioned in close magnetic association with the primary winding 2. The transformer ratios and the tapping point 12 are designed so that at startng the output voltage at terminals 15, 16 is only a proportion of the applied voltage. During the starting period the moving coil 17 moves from association with winding 2 to association with winding 1 in which position the output voltage is higher than the applied voltage and when the moving coil reaches the end of its travel the tapping means is automatically changed over to the running position after which the apparatus functions as a normal moving coil voltage regulator. Various embodiments are foreshadowed in which different arrangements of the primary and secondary windings are made or in which only one secondary winding is used. When used in a multiphase system one regulator per phase is used.

Abstract: 667,141. Gear - finishing. NATIONAL BROACH & MACHINE CO. Oct. 5, 1949 [Jan. 13, 1949], No. 25615/49. Class 83 (iii). A method of finishing a cylindrical gear W consists in meshing the gear with a cylindrical gear-like cutter C having cutting-edges at the leading edges of the teeth, the axes of the gear and cutter being crossed, and rotating the gear and cutter independently in accurately-timed relationship while effecting a slow relative traverse in a direction parallel to the axis of the gear. The cutter C is mounted on a table 20 adjustable angularly about a shaft 24 and is traversed by a screwed shaft 63 coacting with a nut 64 in a slide 13. The work-spindle 16 is vertically-adjustable on a column 11. The cutter C, the work W, and the screw 63 are rotated by an electric motor 25, the traverse of the table being compensated by a differential gear 52, 53. The cutter C may be backed-off as shown or may have unrelieved teeth, the cutter-spindle being then suitably inclined. Alternatively, if the cutter is unrelieved, it may be set with the point of crossed axes spaced from the cutting-edges, the cutter then engaging the work-piece in a position to the left of that shown. The crossed-axis angle is preferably 10-20 degrees. The peripheral surface speed of the cutter is several hundred feet per minute and the transverse rate is a few thousandths of an inch per gear revolution. After one stroke, relief may be introduced between cutter and gear, and the sliide 13 returned rapidly to its initial position. Specification 601,758 is referred to.

Title: Precision grinding
IPC: B24B5/16
Filed: 1959-07-27
Abstract: 858,743. Grinding. CORNING GLASS WORKS. July 27, 1959 [July 30, 1958], No. 25751/59. Class 60. A method of grinding the inner and outer surfaces of the wall of a hollow tapered article to concentricity, consists in first grinding the inner surfaces of the article to concentricity with a lap therein of the desired contour, and then rotating the lap with the article whilst the outer surface of the latter is ground to concentricity with the inner surface. Starting with a blank with a projecting tip, a hole 15, Fig. 2, is first drilled in the tip and, while the blank is clamped in a cage 25, the inner end of the hole is ground out by a rotating lap 20, an abrasive slurry being fed downwardly from a funnel 24. The blank is then inserted and a second lap 30 provided with a reservoir for water and abrasive, is rotated to remove the tip. In the next operation, the blank is supported in an upright position with the small end uppermost by a cage 41, Fig. 4, and a lap 40 of the required shape of the inner surface is introduced into the blank. The lap is driven by a motor 48 whilst an abrasive and a liquid are fed by pipes 45, 46 through a funnelling device 44 to the interior of the blank so that an abrasive slurry passes between the surface of the lap and the inner face of the article. A cable 42 connects the cage 41 with a counterweight 43 enabling an operator to bear downwards on the blank to control the grinding operation. The lap 40 is hollow and has radial passages provided at its up end to which water us supplied to free the blank from the lap on completion of the internal grinding. For grinding the external surface, the blank is rotated about a horizontal axis by the motordriven tail stock spindle of a lathe 65, Fig. 6, the lap serving as the mandrel 61. An external lap 60 having an internal diameter larger than the external diameter of the blank is brought into tangential grinding relation with the lap, Fig. 6a, by feeding the blank in a direction perpendicular to its axis. Water and abrasive supply tubes 67, 66 project into the space between the blank and the inner surface of the lap, and air from an associated supply line 68 maintains a cushion of the abrasive slurry between the lap and blank, which are preferably rotated in opposite directions. Final finishing operations by conventional methods comprise the removal of the base flange 16 from the blank.

Patent GB-259960-A (GB)
Abstract: 259,960. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. Oct. 17, 1925, [Convention date]. Halogenated pyridine compounds. - Iodochlorides of pyridine and its derivatives are prepared by treating pyridine compounds containing iodine in the 3- or 5-position with chlorine. The products are transformed by alkali into the corresponding iodosopyridines and these by heating into iodoxypyridines. The products possess bactericidal properties. According to the examples, (1) pyridine-3-iodochloride is obtained by passing chlorine into a cooled solution of 3-iodopyridine in chloroform; in the same way 2-chloro-5-iodopyridine yields 2-chloropyridine-5-iodochloride ; (2) 2-chloro-5-iodosopyridine is produced when 2- chloropyridine-5-iodochloride is suspended in dilute caustic soda; whilst when steam is blown through an aqueous suspension of 2-choro-5- iodosopyridine, 2-chloro-5-iodoxypyridine is obt.ained. It is stated in the Specification that if 2-chloro-5-aminopyridine, 2 : 6-diaminopyridine, 2-amino-5-nitropyridine or 2-amino-5-bromopyridine be chlorinated, the chlorine enters the nucleus even in the cold. The same is stated to apply to the chlorination of pyridine compounds containing iodine in the 2-. 4- or 6-position: thus, 2-iodo-5-aminopyridine yields 2-iodo-3-chloro-5- aminopyridine on treatment in cold acetic acid solution with chlorine.

Filed: 1931-09-19
Abstract: 392,409. Automatic exchange systems. RUMPF, F., 8, Schwanengasse, Berne, Switzerland. Sept. 19, 1932, No. 26025. Convention date, Sept. 17, 1931. Addition to 391,629. [Class 40 (iv).] In the system described in the parent Specification in which the details necessary for the establishment of a toll call are recorded on a perforated card, the card is carried away on a conveyer and is removed therefrom automatically at the appropriate position for the setting up of the call. As shown, this position is determined by the penultimate digit or letter of the exchange designation, which is registered on the switch BZW. When the punching operations are initiated, contact z closes and a circuit is made over wire an for advancing the switch R to a position marked by the switch BZW, whereupon relay P energizes. Contact l closes when punching is complete. The conveyer band FB has transverse metal strips spaced at intervals corresponding to the positions to which the cards are to be conveyed, and when such a strip reaches and bridges contacts k, the gripping magnet G operates and deposits the perforated card on the conveyer. Relays V, Y energize and prevent further operation of magnet G until the transfer is complete, al. though the punching apparatus is available for use with other recording apparatus. The contacts k also send an impulse to the.switch S, and further impulses are sent as succeeding metal strips pass these contacts until the switch S reaches a position marked by the switch R, when relay X energizes and the gripping magnet at the appropriate position operates to remove the card from the conveyer. Relay P releases and the apparatus restores to normal. Calls may be concentrated when' desired 'at one or more positions by providing switches at either or both the points Kz. The switch S may be marked directly by the 'register switch BZW provided the latter is locked until the transfer is complete.
