Title: Two-wire two-way time division multiplex system
IPC: H04B3/16
Filed: 1957-12-13
Abstract: 823,190. Automatic exchange systems; two-way transmission systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 13, 1957 [Dec. 19, 1956], No. 38844/57. Class 40 (4). In a two-way time-division multiplex a negative impedance amplifier is included in the transmission path. In the exchange system shown, Fig. 1, a channel such as F1 is interconnected with a channel such as F1<1> by causing the energies of the respective channels to be stored on condensers CS1, CS1<1> and causing interchange of the stored energy periodically by closing switches S1 Sh, S1<1> in synchronism, inductance Lh being provided in the common path HW to ensure a complete transfer between the condensers. Each channel is provided with a low-pass filter such as L1/2, C1, L1/2. Other connections may be set up simultaneously over the same highway by using interleaved trains of pulses to the appropriate switches. The energy lost in the switches and inductance is made up (and possibly even an amplification is effected) by the provision of a negative impedance - R in the common path HW. The impedance of the device used may only take on a negative real part in the frequency range to be transmitted and preferably presents a through path to D.C. The transmission band-width of the device should be sufficient to ensure the complete dissipation of energy stored therein in the intervals between pulses. The device must also be open-circuit stable. Special arrangements may be provided for discharging the storage condensers between pulses. Fig. 4 illustrates a suitable device which produces at terminals K an impedance which is a negative version of the impedance R.

Abstract: 1501860 Coaxial cable air seals POST OFFICE 19 Sept 1975 [19 Sept 1974] 40878/74 Heading H2E An air seal is formed on a coaxial cable pair by removing the outer sheathing 4 for a predetermined length to expose the outer conductor 2, exposing circumferentially the dielectric 3 along a length of the exposed conductor 2 and removing circumferentially a strip of the exposed dielectric to expose the inner conductor 1. A perforated metal ferrule 8 is then located over the exposed ends of the outer conductor 2 so as to establish an electrical connection therebetween and a resinous substance is then impregnated over the predetermined length of the cable pair to form the air seal. As described, the ferrule 8 may be longitudinally split or comprise a tubular sleeve and may be crimped into its position over the ends of conductor 2. A second longitudinally split brass ferrule 6, 7 may be situated as shown to bridge the dielectric 3. The outer conductor 2 may be braided, the removal thereof to expose the dielectric being effected by drawing the braiding back after an initially circumferential cut, which may be later pulled back over the ferrule 6, 7. A length of heat shrink plastics tube 9 may cover the heat seal, the resinous substance, e.g. epoxy or polyurethane resin, being forced through an aperture 10 therein to completely fill the spaces via the apertures in the braided ferrule(s). A further tube may enclose tube 9. The method may be employed for coaxial pairs in a multipair assembly (Fig. 2, not shown). A cable pair formed with the air seal as described enables the cable to be passed through a barrier across which a pressure difference exists, e.g. a termination plate of a repeater in a coaxial cable transmission system.
