Patent GB-1196132-A (GB)
Title: An Excluding Device for Automatic Telephone Equipment
Inventor: PUGLIESE GIORGIO
IPC: H04Q3/00
Filed: 1967-06-19
Abstract: 1,196,132. Automatic exchange systems. G. PUGLIESE. 19 June, 1967. No. 28136/67. Heading H4K. A device for preventing the establishment of a connection for a trunk or toll call from a particular line (from a subscriber or PBX) counts the dialling pulses of the first digit and if a predetermined number of pulses is detected inserts a resistor or capacitor in the line to damp the subsequent dial pulses to a level at which they will not operate the selector equipment. As shown when the handset is lifted a first relay R1 is enabled and maintained until the first inter-digit pause is detected. While enabled it holds a non-return pawl n in engagement with a ratchet wheel rd secured to a shaft W. A relay I responds to each dialling pulse of the first digit to increment the ratchet wheel by one tooth. During the inter-digit pause relay R1 is released causing the relay I to be permanently enabled over its hold winding, thus preventing that relay from responding to further pulses. If the number of pulses detected was between 1 and 9 the shaft W is set so that a cam s 2  holds a contact set i 2  closed disabling the relay R1 and thus preventing any response to subsequent digits until after the handset has been replaced on its rest. The remaining dialling pulses are thus allowed to pass unattenuated. If however the first digit is a zero; ten pulses are detected by the relay I and the shaft is rotated into a position in which a cam S 3  closes a contact set i 3  simultaneously with the closing of the contact set i 2 . The closing of the contact set i 3  connects a resistor in the telephone line to suppress the level of subsequent pulses. Several alternative wiring arrangements are described including provisions to prevent false operation immediately following the lifting of the receiver or due to short breaks in line current.

Title: Radio frequency propagating systems
IPC: H01P3/08
Filed: 1955-10-07
Abstract: 780,054. Microwave filters &c. STANDARD TELEPHONES & CABLES, Ltd. Oct. 7, 1955 [Oct. 11, 1954], No. 28620/55. Class 40 (8). [Also in Group XL (a)] A gas discharge tube is positioned to intercept the electric field of a " strip " transmission line. The line consists of a narrow conductor 2 spaced by a solid dielectric layer 3 from a wide conductor 1. Energy is propagated in a mode approximating the TEM mode. A gas discharge tube 5 having lateral extensions 6, 7 containing electrodes 8, 9 is positioned in a cavity formed in the dielectric layer between the conductors. The whole of the dielectric layer may be removed throughout the length of the tube or one or both edge-pieces 13 may be left in position. Impedance discontinuities may be tuned out either by narrowing the spacing between the conductors throughout the length of the tube or by providing small metal tuning stubs 4a, 4b. A variable potential is applied to the tube which may function as a phase-shifter or switch. In the modification of Fig. 5 the narrow conductors 2a, 2b have extensions 16, 17 which are isolated from each other for D.C. current but not for R.F. wave energy by means of a V-shaped gap 18. The wide conductor 1a extends continuously below the lines 2a, 2b and the extensions 16. 17. The latter serve as the electrodes of a gas discharge tube 15 to which D.C. potential is applied via the inner conductors of two coaxial stubs 20, 21. The stubs are tuned by means of conductive pistons 26, 29, the piston 26 being isolated from the outer conductor of stub 20 by a dielectric annulus 27. The outer conductors of both stubs are connected to the wide conductor 1a. The stub 20 is spaced one half-wavelength from the gap 18 with which it forms a resonant section having band-pass characteristics. The stub 21 together with the wide conductor 1a forms a D.C. return path, the plunger 29 being spaced one quarter wavelength from the narrow conductor 2b in order to provide minimum interference with the propagation of R.F. energy. Ionization of the gap 18 changes its susceptance and hence varies the band-pass characteristics of the filter. Specifications 761,761, 761,762, 761,778 and 761,869, [Group XL (a)], are referred to.
