Abstract: 515,922. Sharpening razors &c. ELLIOT, C., July 6, 1938, No. 20051. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 17; 1939.] [Class 60] [Also in Group II] Razor or like blades are sharpened by directing jets of water, alcohol, or other liquids, which may contain a soluble corrosive agent or acid or suspended' polishing powder, steam, compressed air, or other gas obliquely against the sides of the blade so as to sweep outwardly over the cutting edge. As shown in Fig 3, a double - edged blade 6 is resiliently gripped between a pair of flattened water pipes 7 provided with fine perforations or slits 8 to direct water jets obliquely against the sides of the blade in both directions so as to sweep outwardly over both cutting edges. The pipes may extend from a common header 9, Fig. 2, connected ,by a hose 15 to a rubber socket 16 adapted to be slipped over a faucet 17. The header is secured to the end of a shell 10 which may be of transparent material and which forms a combined stand and splash guard, the shell,. being cut away at 12 to facilitate insertion of the blade. A spring clip 13, embracing and movable along the pipes,' assists the gripping action. Alternatively, the pipes may be looped, or may be formed of reinforced rubber integral with a socket adapted to be slipped over a faucet. In the form shown in Figs. 10, 12 and 13, each water pipe 30 has an opening closed by a plate 31 secured to the pipe by Screws 35, small channels 32 being formed in the bevelled seating surfaces of the plate or of the pipe or of both so as to direct jets of water against .the sides of the blade 6 clamped between the plates 31.

IPC: B23B5/26
Filed: 1951-08-27
Abstract: 692,904. Turning piston-rings. GABRIEL CO. Aug. 27, 1951, No. 20172/51. Class 83 (iii). Piston-rings are turned and bored by feeding a series of split-rings with trued side faces in tight contact through a bore, an intermediate part of which is arranged to expose the rings for a turning operation. Stacks of rings which have been previously faced and gapped are placed on the adjustable supports 13, Figs. 3 and 4, and pushed by a hydraulic ram 12 into a stationary hollow cylinder 14 secured to the machine frame by a bracket 15. A depending web 17 from the top of this cylinder serves the dual purpose of engaging the ring gaps and keeping these in alignment, and of supporting a hollow bearing-hub 16. The rings in approaching the end of the cylinder 14 pass into a closing throat 22 and the ends of a spring member 21 engage the gaps to press the rings tightly into the closing portion 43. As the rings traverse a gap between the cylinder 14 and a further cylinder 27 they are rough-turned on the periphery by a rotary tool-head 24 carrying tools 25, Fig. 5, and adjustable work steadies 26. The tool-head is supported for rotation on the outside of the cylinder 14. The rings are held in the cylinder 27 by a further spring arrange. ment 28 engaging the gaps which leaves the bores free to be operated on by a boring-head 41, the spindle of which is supported at one end in the bearing-hub 16. On passing from the cylinder 27 the rings are finish-turned by another rotary tool-head 32 before entering a final cylinder 33 which is connected with an I-section guide 44. The rings slide down on to the d riving-shaft 39, for the internal tools, which is reduced at 45 to the width of the ring gap to allow the rings to move past to the delivery end of the guide 46. The machine may be arranged either horizontally, vertically, or inclined and in operating on thicker rings the boring and turning may take place at the same point in the ring feed.

Title: Method of forcing back electrical coils carried by slotted structure
IPC: H02K15/06
Filed: 1967-05-02
Abstract: 1,119,639. Making coils. GENERAL ELECTRIC CO. 2 May, [1967 [28 July, 1966], No. 20225/67. Heading B3A. A method of forcing back a number of electrical coils carried by a slotted magnetic core comprises the steps of disposing side portions of at least first and second coils in slots of the core; generating at least one surge of electrical energy in the second coil thereby establishing forces acting on the second coil to move it in the general direction of the first coil; and forcing back the first coil by movement of the second coil. A stator core 11 for a four-pole polyphase induction type electric motor has coil g groups 21-24 wound in slots 16 therein. Each group is composed of three coils 26-28, the groups having radial polar centres 29 disposed 180 electrical degrees apart. Standard end turn insulators 30 are placed beneath the coil end turns and a side turn portion insulator (35) is placed in the slots which accommodate coil groups 31-34, F g. 4 (not shown). These coil groups are then wound 60 electrical degrees from coil groups 21-24 and comprise coils 36-38, which are connected to an electrical energy surge source 40. The stator may be supported on an insulated non- magnetic cylinder 47 which projects entirely through the bore. The cylinder also serves to hold the coils in the slots and the end turns clear of the bore. A capacitor bank in the source 40 is discharged and the magnetic inter-action caused by the electrical surge in the coil groups 31-34 forces them radially outwardly in the slots 16, thereby compacting coil groups 21-24 and pushing back the end turns. Further eddy currents are generated in the cylinder 47 to intensify this action. Coil groups 51-54 are next wound on to the core and similarly compacted, thereby further compacting coil groups 21-24 and 31-34. The method of the invention is also applicable to armatures.
