Title: Satellite communication synchronizing system
IPC: H04B7/212
Filed: 1965-09-03
Abstract: 1,084,876. Space satellite communication. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Sept. 3, 1965 [Sept. 8, 1964], No. 37665/65. Heading H4L. The invention relates to a space satellite communication system using one satellite 7, Fig. 1, and n ground stations, wherein the transmissions from the stations are so controlled in time that they arrive at the satellite in successive allocated time slots, in time division multiplex manner. The n adjacent time slots 16, Fig. 2, of width T are contained within a margin frame (A) of width T = n#. In each time slot, an initial guard interval 17 is used to reduce adjacent slot interference, and the rest is occupied by an information burst 21, the initial part of which comprises a synchronization sequence 18 and the latter part of which comprise voice and data chains &c 20. During the synchronization of the station transmissions about which the invention is concerned, only the synchronization sequences are transmitted, and the system operates to position them at the beginning of the allocated time slots. One station is termed the master station, and is allocated to the first time slot and the synchronizing sequences of all the other stations are adjusted in time relative to the synchronizing sequence of the master station. Each synchronizing sequence contains a station identification code. Considering a station allocated at time slot M, this member M is set in time slot selector 37, Fig. 4, which causes a delay of (M - 1) # to be set up in receiver delay 32 and in delay 35 and feeds a delay of (M - ¢) # to control signal combiner 39. Satellite range R and range rate of change R<SP>1</SP> data are also fed into the combiner 39, such that it feeds a signal to transmitter delay 41, such that the station transmits its synchronization sequence so as to approximately fall at 25, Fig. 3, in the middle of time slot M at the satellite. The satellite retransmits the synchronization sequence 51, Fig. 5, such that it is received back at the station and produces an output 55, BS at the output of burst correlation. The synchronization sequence 49 from the master station is received via the satellite as signal 53 and is delayed in receiver delay 32 to produce a signal 57 indicating the desired position of signal 55. Signal 57 and signal 55 are therefore fed to a coincidence detector 34 which is enabled 58 for a period by the output delay 35 and produces a correcting signal 59 equal to the time difference between signal 55 and 57. This is fed to control signal combiner 39, to correct the transmission of the next synchronization sequence transmission. This continues until signals 55 and 57 are coincident, whence a signal is fed to synchronization detector 40 which in turn causes the transmission of the voice data in transmit store 43.

IPC: G01B11/02
Filed: 1972-11-13
Abstract: 1375036 Measuring dimensions photoelectrically VICKERS Ltd 13 Nov 1972 [11 Aug1971] 37811/71 Heading G1A The size of an object is determined by viewing it with a TV camera and monitor system arranged to display two laterally spaced images of the object, the distance between which can be adjusted. In a first embodiment, Fig.1, a microscope 3 with its eye-piece replaced by a TV camera 4 is focused on the object 1, and the resulting video signal Fig.1a is applied directly to one input of a summing amplifier 7 and also via a calibrated variable delay circuit 8 to the other input of the amplifier 7. The resulting signal Fig.1b is displayed on an oscilloscope or TV monitor 10 in the form of two superimposed images the displacement between which is proportional to the delay. This enables the size of the object to be determined e.g. by adjusting the delay until the images just touch one another, the width of the object then being proportional to the delay time. In modifications, a variable gain control (20) is inserted between the summing amplifier and the display unit to provide contrast adjustment Fig.3 (not shown), a colour display unit is used the delayed image being red and the undelayed image being blue, Fig.4 (not shown), and the delayed channel may comprise two parallel variable delay circuits the outputs of which are gated alternately at line frequency so that on the display the image appears to vibrate, Fig.5 (not shown). In a second embodiment, Fig.2 (not shown), the TV camera (4) produces a composite video signal from which the sync pulses are separated and applied to line and frame time base generators (12, 13). The frame scan is applied directly to the display unit 10 and is also squared (17) and triggers a bi-stable divider (18) which produces an output of earth and a positive potential on alternate frames. A proportion of this output is tapped off by a calibrated potentiometer (19) and is added to the line scan signal to provide a lateral shift between alternate frames. This results in the display of two laterally spaced images, the position of one of which can be varied by the potentiometer. In a modification the system utilizes an interlaced scan and the circuit is arranged so that alternate pairs of fields (i.e. alternate frames) are laterally separated by the shift circuit.

Abstract: 1,197,305. Valves. GARRETT CORP. 18 Aug., 1967 [19 Aug., 1966], No. 38247/67. Heading F2V. [Also in Divisions F4 and G3] To prevent the formation of ice in an air conditioning system for an aircraft cabin without limiting the cooling capacity of the system warm air is directed through a by-pass controlled by a pressure operated valve to melt any ice as it forms, the fall in temperature of the air entering the cabin being sensed by a further valve which is operated to control the first valve. Air from the engine is led from a first duct 11 to a cooling heat exchanger 13 and passes to a compressor 17, is cooled again in a heat exchanger 21 to about ambient temperature and then expands in a turbine 22. It is then passed through a second duct 27 containing a temperature sensor 48 and into the cabin. Upon the formation of ice on a screen 24, the pressure in a duct 28 rises and acts on one side of a poppet valve 29. The sensor 48 responds to lowering of air temperature consequent upon the formation of ice and a rod 49 contracts opening a port 53 in a valve 50 to ambient whereby, via a tube 44, the pressure on the other side of the valve 29 is also ambient. Valve 29 will therefore open allowing warm air from duct 16 to by-pass the cooling heat exchanger 21 and pass via ducts 18, 28 to the screen 24 thereby melting the ice. Valve 29 has two metal bellows 31, 32 liquid filled and a connecting orifice 39 which damps movement of the valve 29. A spring 41 provices adjustment of the closing force of the valve.
