Abstract: 644,332. Radio navigation. MINISTER OF SUPPLY. Dec. 4, 1947, No. 32027. [Class 40 (vii)] A presentation means for a hyperbolic radio navigation system comprises indicating means movable in two co-ordinate directions to indicate a position on a chart, means for determining the co-ordinate directions in accordance with the direction of the lattice lines of the system at a destination position, means for obtaining quantities representative of the craft position in said directions with respect to the destination and means for moving the indicating means to a position corresponding with the quantities obtained. Preferably a cathode-ray tube indicator is used with its indicating beam deflected by two sets of movable deflector coils. Deflection currents are fed to these coils of values corresponding to the differences between the respective coordinates of craft and destination and the coils positioned according to the direction of the lattice lines at the destination. If the area represented is small so that the lattice lines may be regarded as substantially straight and parallel a plan position indication of the craft and destination is produced, the destination being at the centre of the tube. It is stated that with a screen having a degree of afterglow the craft position spot will have a tail so that its direction of motion can be seen. Preferably transparent charts corresponding to different destinations are provided such as shown in the Figure. These may be placed over the tube screen and have the destination marked at 2 and the lattice lines therethrough at 3 and 4. Cursors 5 and 6 may be provided on the oscillograph which when moved to coincide with the ends of the lines 3 and 4 correctly position the deflector coils of the tube. Bearing indications 9, concentric range marker circles 10 and indications of holding patterns 11 or obstructions 12 may be shown on the transparent charts.

Title: Communications systems
IPC: H04B17/40
Filed: 1974-07-22
Abstract: 1481108 Data transmission; stations connected on a loop WESTERN ELECTRIC CO Inc 22 July 1974 [25 July 1973] 32338/74 Heading H4P A plurality of transceiving terminals 2a &c. are connected to separate primary and secondary transmission paths together with a base terminal 1 having a means responsive to a reception fault on the primary path which inhibits transmission of signals on the secondary path and a second means responsive to a reception fault on the secondary path operating reversely. Both means may be operable simultaneously. In the embodiment described, the primary and secondary paths are each arranged in a loop, direction of transmission normally being opposite in the two paths. Means are incorporated so that in the event of a fault, incoming signals are re-routed to the other path. Transmitting terminals 2 are connected, with base terminal 1, by primary and secondary loops 3, 4 divided into sections a, b, &c. Data is transmitted from terminal 1 in time divided frames commencing with a sync. pulse followed by time slots unique to each terminal i.e. 2a &c. any form of modulation, e.g. pulse width being employed. Each terminal 2 extracts data appearing in its unique slot and refills the vacated slot with signals destined for terminal 1. In the absence of faults on paths 3, 4, signals on path 4 are transmitted from terminal to terminal unchanged by passage through any terminal 2. Line pairs 5a-5d may be public network trunk lines connected to a central office; line pair, e.g. 5a may be allocated exclusively to terminal 2a &c. Separate fault detectors (10, 11, Fig. 2, not shown) monitor reception on primary and secondary paths i.e. when data is not received for a determined interval a 1 fault signal is given. If a primary fault is indicated on path 3c into terminal 2c, secondary path 4c is disabled and incoming signals on 4b are placed into a data extraction and insertion circuit (12) for passage to a utilizing device, and signals from such device are placed in (12) from transmission over line 3d. A reverse process will also occur to re-rout signals on a secondary path fault. A 1 pulse signal equal to 2 gate delays is applied to the secondary line inhibited which is used to reset circuitry in a terminal the other side of the faulty primary path. Fault detectors in terminals 2 have a greater delay than those in base terminal 1 hence the latter react sooner and the faults on 3c causes cessation of secondary transmission from 1 in addition to the operations in 2c described above. Terminal 2d also reacts similarly. To ensure proper gating of signals received on lines 3, 4 a test transmission is periodically initiated.
