Title: Improvements in or relating to electric switch means
Inventor: SANDBANK HANS ALBERT
IPC: H01H5/18
Filed: 1957-05-07
Abstract: 894,400. Interrupters. ASTABON ELECTRONICS Ltd. May 7, 1958 [May 7, 1957], No. 14573/57. Class 38 (5). A thin blade 1, preferably of berylliumcopper, is fixed at one end to the switch body 2 by an insulated terminal 3 connected to the blade 1, and carries at its other end contacts 4 and 5 for co-operation respectively with adjustable contacts 6 and 7 insulatingly mounted on the body 2. The contacts are preferably of 20% iridium-platinum. A tongue 9 is cut out from the blade 1 and is compressed into an arc by an insulating member 11, adjustably mounted on body 2, such that the side strips 8 and 10 are in tension, thereby biasing the blade 1 to bring contact 4 into engagement with contact 6. A cam 13 is formed on the end of a hardened steel spindle 14 rotatable in an eccentrically-mounted bearing 18 by a gearing train from an integrating meter. A cam-follower 12 of sapphire is mounted on blade 1 and under action of cam 13 causes the blade 1 to oscillate with a snapaction between contacts 6 and 7 and may thereby produce electric pulses to operate a remote counting device such as in Specification 892,486. To avoid contact bounce due to oscillation of the thin tongue 9 and strips 8 and 10, pieces 18 and 19 of a material having a low coefficient of friction are attached to the tongue and strips respectively and are in frictional engagement. These are stated not to affect the travel of follower 12 nor the torque needed to actuate blade 1.

Title: Improvements in and relating to automatic switching systems for balancing direct current electrical circuits
IPC: H02J3/06
Filed: 1930-05-12
Abstract: 354,730. Balancing supply voltages. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Bany, H. ; 904, Myra Avenue, and Seeley, H. T. ; 512, Orchard Avenue, both in Yeadon, Pennsylvania, U.S.A.) May 12, 1930, No. 14577. Convention date, May 10, 1929. [Class 38 (iv).] Automatic reversible motor regulators. A D.C. balancing set 1, as shown in the Figure, comprising the two machines 2, 3, is connected to a supply' system 4, 5, 8 through switch 7 in the main leads and 9 in the neutral lead. The set is started automatically on the occurrence of " out-ofbalance " in the supply system by means of a relay 18 which completes the operating coil circuit of a time-delay relay 21 which in turn energizes master relay 22 through auxiliary contacts on the starting device 23 and auxiliary contacts on relay 22 then complete the circuit for switch 7. The starting device 23, which is of known form, shortcircuits series resistances 24a, 24b as the set 1 runs up. When the starting operation is completed relay 37 closes and the polarized relay 29 controls the field rheostat motor 35 to regulate the fields of the set 1. The fields are connected in series across the set terminals through a field resistance and the moving contact 14 of the rheostat is connected to the neutral. The polarized relay 29 has one coil 30 connected across the open switch 9 and another coil 31 in series with the neutral 8. Closure of contacts 70 or 77 energizes relays 34 or 36 respectively to energize the rheostat motor 35 through contacts 68 of relay 37, back contacts 73 of switch 9 and contacts 71 or 78 of the relays 34 or 36. When the neutral voltages of the line and set are equal the contacts 70, 77 are open and contacts 84, 82 on relays 34, 36 and contacts 68 on relay 37 are closed to energize operating coil 86 and close neutral switch 9. Auxiliary contacts 73 on switch 9 are now open and control of the rheostat motor 35 is taken over by relay 40 operated by coils 41, 42 connected across the supply system. When the current through the neutral exceeds a predetermined value current limit relay 44 is energized to remove control of the rheostat motor 35 from relay 40 to polarized relay 29. In the event of the neutral current exceeding a predetermined value when the field rheostat has been operated to its fullest extent limit switches 99, 100 close a circuit for relay 46 which opens the retaining circuit for the winding 39 and opens the neutral switch 9. The switch 9 may be reclosed when the neutral voltages are equal as described above. Should the neutral current fall below a predetermined value timedelay relay 47 is energized through auxiliary contacts on relays 34, 36 and if the drop in current persists relay 47 opens and breaks the retaining circuit for master relay 22 to shut down the set. A lock-out relay 48 shuts down the set if the starting operation is not completed within a predetermined time and is reset manually.
