Title: Improvements in or relating to the testing of armatures of dynamo-electric machines for electrical faults
IPC: H02K15/00
Filed: 1944-02-11
Abstract: 592,221. Detecting, indicating, and locating faults. GENERAL ELECTRIC CO., Ltd., and WARD, L. G. Feb. 11, 1944, No. 2548. [Class 37] Faults in armature windings are detected and located by producing on the screen of a cathode-ray tube an image representing in succession the impedances of each individual circuit connecting consecutive commutator segments. A bed 10, Fig. 1, carries at one end a motor having a chuck 12 on the end of its shaft. An insulating slip-ring 13 is fast on the motor shaft and has a single narrow conducting segment 14 which bridges once per revolution a pair of contacts 15, 16 carried by a holder 18, thereby triggering the time base of a cathoderay oscillograph. The holder 18 is so mounted that the triggering contacts 15, 16 are angularly adjustable through 360 degrees. A brushholder 28 is adjustably clamped to the bed 10 and carries two fixed supply brushes 29, 30 for supplying current to the armature windings and also a pair of pick-up brushes 32, 33, Fig. 2, spaced apart by the pitch of the commutator segments. The brush-holder 28 is diametrically divided and hinged at 34 to allow the armature under test to be inserted. The armature 25 to be tested is mounted with one end held in the chuck 12 and the other supported by a spring-pressed centre 21 carried by a tailpiece 20. Current is then applied to the supply brushes 29, 30 and the motor started. A series of lines 35, Fig. 3, are produced on the screen of the oscillograph by the voltage between the pick-up brushes 32, 33 with normal impedance between pairs of adjacent brushes. An open circuit or high impedance is represented by a long line 36, while a very short line 37 indicates a short circuit. The triggering contacts 15, 16 are then adjusted about the armature axis until the fault indication is brought to the end of the image, so that when the armature is brought to rest the pick-up brushes rest on the segments connected to the fault at the same time as the triggering contacts 15, 16 are bridged by the bar 14.

Patent GB-668233-A (GB)
Title: Improvements in and relating to apparatus for longitudinally slitting travelling webs of paper, cardboard or other materials
IPC: B26D1/24
Filed: 1950-02-01
Abstract: 668,233. Cutting-machines for paper &c. MASSON, SCOTT, & CO., Ltd., and MOSER, H. W. Nov. 17, 1950 [Feb. 1, 1950], No. 2596/50. Class 31 (i). Apparatus for longitudinally slitting travelling webs of paper, cardboard or other material of the kind comprising one or more pairs of overlapping disc cutters supported on opposite sides of the web is characterized by separate and transversely displaceable mountings for the disc cutters of each pair and means for temporarily connecting the mountings so that the cutters can be adjusted transversely in unison without disturbing their cutting relation, the temporary connecting means being arranged so that it can be withdrawn to leave a free path for the web after the desired transverse adjustment has been effected. In the form shown, the upper cutter 18, which is freely rotatable, is mounted on a carriage 1 slidable upon a fixed shaft 2, and the lower cutter 7, which is driven from a shaft 10, is mounted on carriage 4 slidable upon a fixed beam 5 having a dovetail guide 6. The carriage 4 is provided with a plunger 31 which is movable into a bore 32 in the carriage 1, to connect the two carriages together, by means of a manually-operable crank 38 connected by a link 41 to the lower end of the plunger. When the plunger 31 is moved into the bore 32, the upper end of the link 41 rocks a pivoted member 44 to lower a spring- controlled wedge 45 so as to release the carriage 4 from clamping engagement with its guide 6, and, at the same time, the upper end of the plunger 31 moves a spring-loaded wedge member 34 upwardly from clamping engagement with the shaft 2 so as to release the carriage 1. The carriages are then adjusted transversely by means of a manually-operable pinion 15 which engages a rack 17 on the guide 6. The adjustment is facilitated by a graduated scale 47. After the adjustment has been made, the plunger 31 is withdrawn from the bore 32 and this causes the carriages to be re-clamped in position. If a web is present in the apparatus when it is desired to move the plunger 31 into the bore 32, the nose 31a of the plunger is given a chisel-like form so that it can readily penetrate between the slit edges of the webs. The cutter 18 is mounted in a yoke member 22 carried by a spindle 25 adjustable vertically in the carriage 1 and the cutter can be rocked out of engagement with the cutter 7 by means of a handle 23. The temporary connection may be formed by a geared or other drive between separate transverse adjusting means for the respective cutter mountings, e.g. each mounting may have a rack- and pinion adjustment, and a withdrawable gear or geared spindle be provided for operatively connecting the pinions. Other adjustment means, e.g. screw and nut arrangements, can be employed.
