    This paper describes a new type of magnetic amplifier having inherent self-balancing potentiometer characteristics. By means of a special compound feedback circuit, extreme stability and the fulfillment of balance conditions in the control circuit are obtained. Positive external feedback or self-feedback produces an effectively infinite gain that is highly degenerated by negative feedback resistan... View full abstract»

    THE growing need for improved types of data storage systems in both the digital computer and telephone switching fields has led to the investigation of ferroelectric materials as memory devices. Among the objectives in developing these devices have been low power consumption while storing or reading out information, memory access times of 1 microsecond or less, small size per bit of memory, simpli...

    RADIO receivers respond to radio transmitters by virtue of antennas which couple them both to free space. As compared with wires, free space is an inefficient coupling medium, and it has erratic efficiency changes. These changes are well known as fading, skip, and sporadic effects, which vary with distance, direction, frequency, and time. View full abstract»

    THIS paper describes a new general-purpose electromagnetic relay for use in telephone switching systems. It is a wire spring relay known as the AF-type relay and, with variations which provide slow release or marginal characteristics, it is known as the AG and AJ relay respectively. Figure 1 shows a typical AF-type relay, Figure 2 shows all of the parts of the relay, and Figure 3 shows the relay a... View full abstract»

  • Type-O carrier telephone

    Publication Year: 1953, Page(s):428 - 437

    TYPE-O carrier, the most recent addition to the carrier series, is designed to supply additional telephone circuits to the many communities served by open-wire facilities. This new system supplements, rather than supersedes, the older open-wire systems such as types C, H, and J. Type-C and J carrier systems were designed primarily for long circuits, 2,000 miles or more, and consequently cost more ... View full abstract»

    IN 1946, the authors disclosed a new design for an a-c network analyzer1 operating at 10,000 cycles. The pilot-model analyzer reported at that time was used extensively during the next 2 years upon small sample systems for testing its performance. View full abstract»

    THE magnetic amplifier and magnetic devices in general have garnered an enviable reputation for reliability and maintenance-free operation1 in their not-so-short history.2 For these reasons these devices have been a subject of considerable interest3, 4 to the computer field wherein electron tube failure is a major headache. There have been many magnetic devices developed for use in this field, but... View full abstract»
