Title: Improvements in apparatus for printing impressions upon a continuous strip
IPC: B65H23/188
Filed: 1962-05-28
Abstract: 975,741. Printing apparatus. R. J. KIECKHEFER. May 28, 1962 [Sept. 20, 1961], No. 20432/62. Heading B6C. [Also in Divisions G3 and H2] Relates to apparatus for imprinting and decorating a metal strip 5 passing from supply reel 7 to a take-up reel 11, the rotation of roller 16, which carries an image to be reproduced, being synchronized with the lengthwise motion of the strip, so that successive impressions made by the roller are at uniformly spaced predetermined intervals along the strip. The roller 16 is driven by synchronous motor 20 through transmission 47 providing coarse adjustment, and transmission 48 adjusted by two-phase servomotor 30. Synchros 25, 26, are driven by the strip and roller 16 respectively, the rotor of the machine 25 being connected to a source of reference A.C., whilst the stators of the two machines are interconnected. The rotor of machine 26 is connected through amplifier 27 to one phase of motor 30 whose other phase is connected to the reference A.C. source. When the relative angular positions of monitor roller 24 and roller 16 differ, the servomotor 30 is rotated to adjust transmission 48, whereby the speed of roller. 16 is varied to return it back into angular correspondence with the monitor roller. The rollers are brought into approximate synchronization, before automatic control is placed in operation, by manual adjustment of transmission 47 in co-operation with null meter 50. A transformer 53 has one primary connected to the reference A.C. source and another primary connected to the rotor of machine 26 through phase shifter 58. The secondary output of the transformer is a measure of the phase displacement between the output of synchro 26 and the reference A.C., and is rectified and filtered before being applied to the meter. Several rollers 16 may be separately driven and each associated with an individual syncho 26 linked with the other synchros.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1925-08-15
Abstract: 261,109. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), (Polinkowsky, L.). Aug. 15, 1925. Automatic exchange systems; metering. - A relay at a switch at the outgoing end of a trunk energized over the two line conductors in series, is de-energized by opening a bridge across the incoming end of the trunk to cause the advance of a sequence switch at the outging end. The invention is described as applied to a registercontroller system in which a calling line SS1 is extended in known manner to a wanted party SS2 over first and second line finders LF1, LF2, an outgoing selector GS1, and an incoming selector GS2 and connector FS at the distant exchange. When the connector wipers arrive on the wanted line, the sequence switches at the selectors GS1, GS2, and connector FS are in their waiting positions 10, 13, and 7 respectively, in which the primary winding of the busy tone coil BTC is bridged across the incoming line wires at the connector, and a supervisory relay S3r at the selector GS2 thereby energized, whilst a relay Agr is bridged across the incoming junction at the selector GS2 causing the response of a similar relay Csr at the proceeding selector GS1. If the wanted line is busy, the tone coil remains in bridge, and a signal is sent back. When the calling party hangs up, the relapse of the line relay ASr energizes a metering preventing relay Nmr and opens the loop over the junction to initiate release. If the called line is idle, the connector sequence switch advances to ring- ing position, and on reply to talking position. Between these positions the bridge at the connector is opened and the relay S3r relapses and drives the sequence switch at the selector GS2 to its talking position 15, in moving to which the bridge at this switch is opened and relay CSr de-energizes and drives the sequence switch at the first selector GS1 to its 11th position. On the reclosure of the bridge at the selector GS2, the relay CSr re-energizes and drives the sequence switch at the selector GS1 to its twelfth or talking position. When the calling party hangs up, the line relay ASr drives the sequence switch at the first selector to normal, and metering current is connected to the third wire to energize the meter SM. If the called party hangs up before the calling party, the relapse of the relay S3r lights a lamp GL and may also operate a time alarm.
