Patent GB-2086188-A (GB)
Title: Repertory dialler
IPC: H04M1/27495
Filed: 1980-10-09
Abstract: In a repertory dialler it is often desired to restrict access to the repertory store, e.g. where it contains confidential numbers or to prevent malicious access to that store. To permit this, the user has to key in an identification (ID) code to give him access to the repertory store (F). When a call is initiated the first digits received are compared by a comparator (C) with the ID code as stored in a store E. If there is disparity, the repertory dialler facility is disabled. However, if the comparator (C) shows that the correct ID code is received, it renders the repertory facility effective. When this occurs, the caller dials the special short code for the wanted number, which is then sent from the store (F) to the exchange. <IMAGE>

Patent GB-2102232-A (GB)
Title: Optical fibre system
Inventor: CHOWN DAVID PHILIP MARTIN
IPC: H04B10/27
Filed: 1981-06-02
Abstract: A data transmission system uses a single optical fibre highway (4) for data transmission on a bi-directional basis. The two directions of transmission are separated on a bi- directional basis, and each terminal only has one light detector (7), which is so coupled to the highway via optical couplers (2, 3, 1) that it can receive light from either direction. The central circuitry (8) of the terminal is also connected to a light source (6), which supplies light for an outgoing message to both directions. The timings are such that messages can pass simultaneously in both directions through the highway, being interlaced in time when arriving at each terminal's receiver. Each message traversing the system is regeneratively repeated at each station via which it travels. Two of the couplers (2, 3) are also connected via a low-loss bypass (10) which is normally disabled, but is rendered effective when the terminal fails, so that continuity is maintained. In a second version of the system, separate light sources are provided for the two directions of transmission and continuity is maintained if a terminal fails via an attenuator between that terminal's optical couplers. <IMAGE>

Title: Fire and explosion detection and suppression
Inventor: FARQUHAR ROBERT LINDSAY
IPC: G08B17/12
Filed: 1982-07-19
Abstract: To initiate fire or explosion protection action in, for example, an armoured vehicle when an exploding ammunition round causes or is about to cause fire or explosion of hydrocarbon fuel D from, for example, a ruptured fuel tank 8 (Fig. 1B) but not to cause suppression action when the only fire or explosion is that of the round itself (Fig. 1A), a radiation detector 10 measures the ratio of the intensity of the radiation at 3.4 and 4.4 microns. When (Fig. 1B) a round passes through the fuel tank 8 entraining initially unburning hydrocarbon fuel D with it, the detector 10 measures a relatively low ratio because the fuel vapour between the burning round and the detector 10 has a very intense absorption band at 3.4 microns. Fire suppression is thus initiated, so as to suppress the hydrocarbon fire which would very shortly follow. If the round (Fig. 1A) does not strike the fuel tank 8 and hydrocarbon fuel vapour is not present, the ratio measured by the detector 10 is higher and explosion suppression is not initiated. <IMAGE>
