Title: Improvements in or relating to systems for indicating the position of hits on targets electrically
Filed: 1932-04-20
Abstract: 390,645. Electric signalling systems. MÍSER, W., 4, Lutherplatz, Dessau, Anhalt, Germany. April 20, 1932, No. 11293. Convention date, April 25, 1931. [Class 40 (i).] In a system for indicating the positions of hits on targets, an impulse sender is adapted to be connected by a change-over switch to one or other of a pair of indicators which respectively indicate the ring number and position of the hit. As shown in Figs. 2 and 3, the ring number indicator 1 or the hit-position indicator 2 may be connected to the impulse sender 18 by the change-over switch 15. The marksman upon firing a shot, signals to the butt by depressing a button 3 which locks up a circuit including signal lamps 5, 8. Upon operation of lamp 8 the attendant at the butt depresses button 10 of the switch 11 to extinguish lamps 8, 5 and release the button 3 and simultaneously connect the indicators 1, 2 to the change-over switch 15 and impulse sender The impulse sender 18 is then operated in accordance with the ring number of the hit and impulses are transmitted over switch 15 in its normal position to operate the indicator 1 step-bystep. The hit position is then signalled by depressing the change-over switch 15 and again operating the impulse sender 18 to position the indicator 2 which comprises a lamp 54 mounted on the ratchet wheel. When the impulse sender restores to normal, off normal contact 22 is closed to illuminate the lamps 33, 50 .. 53 and the indicator lamps 36, 54. At the termination of signalling button 12 of the switch 11 is depressed to disconnect the indicators 1, 2 from the impulse sender. A plurality of switches 11 corresponding to different marksmen are provided to facilitate the use of a common impulse sender. The indicators 1, 2 are restored to normal by operation of an impulse sender 38. The resetting circuits of the indicators include contacts 30. 31 which are opened automatically when the indicators assume their normal positions. Operation of the resetting impulse sender also extinguishes the lamps. In a modification the change-over switch comprises a pair of mercury tubes, one or other of which is rendered operative according to the position of the switch. In this arrangement the indicators are in the form of lamp groups controlled by ratchet-driven switches, which are adapted to be restored to normal by self-interrupting pendulum switches. The Specification as open to inspection under Sect. 91 describes constructional forms of indicators, the ring number indicator comprising a ratchet-driven disc or drum, Figs. 5 and 6 (Cancelled and not shown), and the hit indicator comprising a lamp mounted on a rotatable arm behind a transparent indicator dial, Figs. 7 and 8 (Cancelled and not shown). This subject-matter does not appear in the Specification as accepted.

Abstract: 775,398. Grinding. GLEASON WORKS. April 19, 1955 [April 19, 1954], No. 11295/55. Class 60 [Also in Groups XXII] A method of simultaneously cutting opposite sides 18, 19 of spaced teeth of a. face-toothed clutch or coupling member 10, as described in Specification 572,612, by a rotary cutter 14, consists in relatively feeding the cutter to full depth while the member is held against rotation and then finish cutting by feeding the cutter at an angle to the direction of relative feed to remove stock, from the said sides. After the cutter has been fed axially to depth it is moved about an axis 21. The bottom and side cutting edges 27, 28 are thus moved out of the cut and each tooth is finish cut by the edges 13 under the same conditions. For teeth with zero pressure angle the cutter axis 43, Fig. 5, is inclined to the work axis 44 and is pivoted about an axis 48. Alternatively, the cutter may be partially withdrawn and pivoted about an axis 55, Fig. 7. In grinding machine for carrying out the method, the member 10 is mounted on an axially adjustable spindle on a vertically-adjustable slide 66 on a column 63 angularly adjustable on a slide 61. The member is indexed by means 68 driven in timed relation with cams 78, 84 which control the movements of the grinding wheel 16. The wheel is mounted on a slide 73 swung about a pivot 76 by bevel gearing 88 turned by a lever 86 contacting the cam 84. The slide 73 is supported by a slide 74 moved axially by the cam 78 through a lever 79 and a pivot block 83. Reference has been directed by the Comptroner to Specifications 572,612 and 594,492.

Filed: 1950-05-08
Abstract: 704,455. Printing-machines. HALLEY & SONS, Ltd., J., and HALLEY, A. M. May 4, 1951 [May 8, 1950], No. 11318/50. Class 100 (2) In a rotary printing machine the printing cylinder is mounted at each end in a lever which may be rocked (a) by a cam on a worm-driven shaft for adjusting the printing pressure, and (b) by twc adjustable eccentric bushes carrying the shaft whereby the latter may be moved laterally to provide a rapid withdrawal or resetting of printing contact. The printing cylinder is mounted in bearings 3 (one shown) in levers 4 with pivotal connections 5 to the machine frame. Pivoted to each lever 4 is a link 7 to which is connected a slotted extension 8 surrounding a shaft 9. The combined length of the link 7 and extension 8 can be adjusted by moving bolts 13 in a connecting plate 10. Each extension 8 carries a roller 15 engaging a cam track 16 in a disc 17 fixed eccentrically to the shaft 9, which is itself mounted in eccentric bores 18 in bushes 19 rotatable in the side frame 20. Pivoted on the bushes are links 22 slidable in guides 23 on the side frames and pivotally connected to links 24 pivoted to a vertical slide 25. The slide 25 is connected to the piston 26 of a pneumatic cylinder 27. At one end of the shaft 9 in a housing 29 is a worm wheel 28 meshing with a worm 30 on a spindle 31. By rotating a hand-wheel 32, the worm gear rotates the shaft together with discs 17, thus raising or lowering the links 7 and thereby rocking the levers 4 to set the printing cylinder relative to the impression cylinder. When the machine ceases to operate an air valve is automatically operated to lower the piston rods 26, thereby rocking the links 24 and causing a partial rotation of the bushes 19 to move the shaft 9 together with the housing 29 laterally. This movement is transmitted through the discs 17 to the links 7 and rocks the levers 4 to trip the printing cylinder. The machine may have two cylinders similar adjustment mechanism being provided for each cylinder, the slide 25 being connected to a second link 24a similar to link 24. If the machine has more than one pair of cylinders, the slide 25 may be extended and connected to a second pair of links 24, 24a, so that both pairs are operated simultaneously.
