Patent GB-776588-A (GB)
Abstract: 776,588. Loud-speaker systems. SVENSKA RELAFABRIKEN AKTIEBOLAGET. July 19, 1955 [Dec. 14, 1954], No. 20928/55. Class 40 (4). In a loud-speaker intercommunication system having a channel including an amplifier incorporating voice-operated blocking means for each direction of transmission, a pair of relays TR<SP>1</SP>, TR<SP>2</SP> controlled by keys TK at subscriber's stations are operated during a call to a station in a noisy locality to disconnect one amplifier and to control the effective direction of transmission of the remaining amplifier during the call, respectively. The operation of a calling key K energizes relay AR at the local station and relay BR at the wanted station to complete a four-wire circuit in which instruments M which are dual purpose loud-speaker microphones are used as microphones for working to loudspeakers H over amplifiers I and II. Busy lamps L are lit at all stations by the operated relay AR. When key TK is operated to overcome operation of the directional switching by noise amplifier I is used for both directions in a two-wire circuit terminated by the instruments M<SP>1</SP>. Relay TR<SP>1</SP> is locked up over a circuit including contacts of the operated relay AR. Specification 732,028 is referred to.
Patent GB-778540-A (GB)
Abstract: 778,540. Synchronous motors. AKT. GES. BROWN, BOVERI & CIE. Jan. 25, 1956 [Jan. 25, 1955], No. 2499/56. Class 35. A commutatorless converter motor whose armature is supplied through converters from a D.C. or A.C. supply and whose field is D.C. excited, is provided with an armature-reaction compensating winding, e.g. in the pole-faces, so that the ignition phasing of the converters need not be adjusted for load. As shown, for a motor 5 whose armature windings 2 are fed from D.C. source 6 through inverters 7 whose firing is controlled by a device 8, the armature reaction compensating winding 4 is connected in the D.C. load circuit. The field winding 3 is separately excited. If polyphase supply is available this may be rectified and supplied to terminals 6, or may be fed to the armature direct through a frequency-changing converter, in which case the compensating winding is fed through rectifiers from current transformers in the input lines.
