Filed: 1970-02-19
Abstract: 1299427 Selective signalling BRITISH AIRCRAFT CORP Ltd 19 April 1971 [19 Feb 1969] 8047/70 Heading G4H An electrical communication system includes a transmission line connected at one end to a transmitter and terminated at the other end by the characteristic impedance of the line, and at least one receiver connected to an intermediate point along the line, the receiver including encoding means operative during a transmission to the reveiver to intermittently load the line with an impedance, whereby the resulting characteristic variations in the line voltage constitute a binary coded response to the transmitted signal. The transmitter selects the receiver in turn by transmitting a chain code which is recognised by a shift register in the appropriate receiver. The states of manual switches in the selected receiver are encoded, and in response to a train of pulses on the line from the transmitter, the pulses of the encoded results are each used to connect the impedance mentioned to the line, the resulting pattern of variations in line voltage being decoded at the transmitter and used to effect indication or control. The load impedance in each receiver has the same value as the terminating impedance of the line, which is a coaxial cable. The system can be used for passenger requirement signalling in an aircraft.

Title: Improvements in or relating to pulse transmission systems
IPC: H04J3/06
Filed: 1956-03-16
Abstract: 799,150. Pulse modulation circuits. TELEFONAKTIEBOLAGET L.M. ERICSSON. March 16, 1956 [March 16, 1955], No. 8352/56. Class 40 (5,). In a multi-channel pulse communication receiving system an abnormal pulse in a regular pulse train, Fig. 2a, is detected by applying the pulses, Fig. 2b, and a wave of pulse recurrence frequency, Fig. 2c, to a gating circuit. The pulses, Fig. 2a, applied between 0 and 1, Fig. 1, are reversed in polarity at the anode of V1 and applied to the gating circuit comprismg diodes D1, D2 and transformer T. The high-Q resonant circuit L1, C1 tuned to the pulse recurrence frequency maintains by means of the feed-back winding L2 an unvarying sinusoidal voltage, irrespective of the appearance of an abnormal pulse, whose maximum negative value concides with the negative pulses except when an abnormal pulse appears. The anode of D2 is given a lower bias voltage than the cathode of D1 both diodes thus being blocked, and normally no current passes through T. The abnormal pulse appears as a negative pulse on the cathode of D1, the anode of D2 being simultaneously fed with the positive half-cycle of the sinusoidal voltage. The diodes thus conduct for the duration of the abnormal pulse and current passes, and the pulse appears, Fig. 2d, at the output winding of T. In a further embodiment, Fig. 3, a positive pulse train, Fig. 4a, is fed to the control grid of V3 which is biased to cut-off for the duration of the applied pulses causing a sinusoidal voltage at the resonant circuit L1, C1. The voltage of the suppressor grid inductively coupled by winding L2 varies in phase with the screen voltage, Fig. 4c. Applied pulses normally appear when the screen and suppressor grid voltage are minimum, the suppressor grid voltage being lower than the cut-off voltage V-stryp, Fig. 4c, of the suppressor grid so that no anode current flows. An abnormal pulse occurs when screen and suppressor grid voltages are maximum, thus causing anode current to flow and pulses to appear at output terminal 2. An application of the invention to a multi-channel pulse system comprising two terminals and intermediate relay stations, and a subroute between one relay station and a third terminal, is described wherein the channel-pulses to be branched are selected at the relay station, their time positions being such that their pulses appear in the middle of the respective pulse intervals.

An insulated shipping container comprises a rigid pallet 10 with skids 11 and a flexible fabric-like gas-tight bag 12 adhered to the pallet 10 with a rigid load supporting, insulating body 13 therein. An inner gas-tight bag 13 is adhered to the body 13 and a flexible annular diaphragm 20 provides a gas-tight closure for the bags 12, 15. The space within the bags 12, 15 is filled with a soft, expandable, contractable insulating material 14 (which may be intercellular, foamed elastomeric plastic material) with an elastic memory. An expandable, contractable door 22 faced by a rigid panel 23 is mounted in a frame 21 on the diaphragm 20 to provide access to the container. In order to load the container the door 22 is removed and air is exhausted from the material 14 through a valve 26. The bags 12, 15 collapse, horizontal collapse being restricted by flat spacers 16. In the collapsed condition (Fig. 2) packages of frozen food 28 may be loaded and retained by tension straps 27 passing over a rigid tie plate 29. Air is then allowed into the material 14 and its elastic memory restores its original form (Fig. 1), when the door 22 is fitted and held in place by bars 24 passed through loops 25. Expansion from the collapsed portion may be expedited by forcing air into the material 14. Rings 31, 32 looped respectively to bags 12, 15 may replace the spacers 16 (Fig. 6) or rings and flexible spacers may be used (Figs. 7, 8, not shown). The container need not necessarily be mounted on a pallet, any insulated base, e.g. similar to the side walls, might well be used.
