Title: Improvements in automatic telephone systems
IPC: H04Q3/62
Filed: 1927-01-31
Abstract: 289,182. Siemens Bros. & Co., Ltd., and Christian, D. A. Jan. 31, 1927. Automatic exchange systems; metering.-In a system in which the release of connections to certain parties is under the control of the calling party or of either the calling or called party whilst the release of connections to other parties such as a. manual operator is under the control of the called party only, the circuit changes which determine the different conditions of release are effected at a feed group-selector by the setting of the selector itself, being thus independent of signals sent back from the called end of the connection. Fig. 2 shows a selector in which the release relay V first energizes over rotary offnormal contacts w and is held during conversation over series contacts a<1>, y2 of the line relay A and the answering supervisory relay Y respectively, so that for calls to other automatic subscribers release will occur when either subscriber hangs up. The selector is provided with an additional vertical wiper vc, the associated bank being so wired that for calls to an operator an alternative holding circuit v5, vc, l4, y2 prevents the release of relay V when the calling party hangs up. The extra wiper and bank may also be employed by means of connections over contacts y3 to the test wire to record the number of internal calls made over a particular level or levels by a calling party such as a private branch exchange subscriber or extension. In a modified selector in which connections are normally released when the calling subscriber hangs up, the extra wiper connects battery over a front contact of the answering supervisory relay directly to the release relay for calls to an operator, whilst for calls to automatic subscribers the extra wiper completes a circuit for the initiation of delayed-metering arrangements of well-known type.

Title: Improvements in or relating to the speed control of electric motors
Inventor: MACKENZIE Donald
IPC: H02P8/12
Filed: 1963-01-24
Abstract: 1,010,571. Stepping motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 24, 1963 [Jan. 24, 1963], No. 3051/63. Heading G4H. [Also in Division H2] A polyphase synchronous motor has its phase windings energized in sequence by pulses of direct-current, the speed of the motor being determined by the cyclic rate at which the phase windings are energized and the direction of rotation being determined by the sequence in which the phase windings are energized. Semiconductor controlled rectifiers DA, DB, DC, are connected respectively in series with phase windings A, B, C, and are associated with quenching rectifiers DX, DY, DZ. The cyclic rate at which rectifiers DA, DB, DC, are rendered conductive depends upon the frequency of pulses applied to line 3. If the rectifier DA is initially conductive, for example, capacitor CAY is charged, and when the next positive pulse appears on line 3 and is applied through diode XD and capacitor CX to the trigger electrode of rectifier DX, the latter is rendered conductive. The other diodes BD-AD are back-biased to prevent the pulse being passed to the other controlled rectifiers. The next positive pulse on line 3 triggers rectifier DB, both phase windings A, B, being energized, while capacitor CY is conditioned so that the next positive pulse renders rectifier DY conductive. When the rectifier DY commences to conduct, a negative-going pulse is applied from its anode through capacitor CAY to the anode of rectifier DA. This renders the rectifier DA non-conductive. The phase windings A, B, C, are thus energized in sequence, the speed of the rotating magnetic field being dependent upon the repetition rate of the pulses. The sequence of firing may be reversed by associating a twoposition switch, with each controlled rectifier, Fig. 3 (not shown). The trigger electrode of controlled rectifier DA receives a positive pulse through capacitor C1 when a starting switch is closed. This pulse dies away as a charging current flows through Zener diodes Z1, Z2, and resistor AR. Protective diodes DIA, DI, are provided. These additional components are duplicated for each of the windings B and C.
