Title: Tape-sensing devices for telegraph transmitters
IPC: H04L17/12
Filed: 1952-10-14
Abstract: 710,749. Type printing telegraphy. TELETYPE CORPORATION. Oct. 14, 1952 [Nov. 1, 1951], No. 25727/52. Class 40 (3) In a tape-sensing device for actuating a telegraph transmitter by signals recorded as code combinations of apertures in a tape, the members which are utilized to sense the presence or absence of apertures in the tape are each so pivotally connected to a corresponding movable contact blade positioned opposite a pair of fixed transmitter contacts that when a sensing member encounters an aperture, the movable contact blade is caused to pivot, at least initially, about one contact of the pair of fixed contacts so that it is brought into engagement with the other fixed contact of the pair. The pins 17 for sensing the holes 11 in the tape 12 are carried by levers 18 of insulating material formed with laterally projecting studs on which are pivoted contact blades 22 of conductive material such as copper. The levers 18 are formed with abutments 26 engaged by the ends of coiled springs 23 which at their opposite ends are attached to a rod 24. The blades 22 have V-shaped notches 37 engaged by the shaped ends of springs 36 whose other ends are passed round a rod 38 and tend to move the blades 22 towards the marking contact 28. The blades are held against the spacing contact 27 by a bail roller 31 mounted in a bail frame 32 reciprocated by an arm 41 driven by an eccentric 47 on a shaft 48 and formed with an extension 42 engaging an aperture 43 in a downwardly extending arm of the bail member. When the bail roller 31 is raised and a pin 17 encounters a perforation the associated lever 18 causes the connected blade 22 to pivot about the spring contact 27 into engagement with the marking contact 28 and then to rock on the contact rod 28 out of contact with the rod 27. In the rest or non-operative position the end 57 of the armature 53 of a magnet 52 in the de-energized condition engages a notch 58 in a depending arm of the bail member which is latched out of engagement with the lever 41. The energization of the magnet 52 allows the bail member to rotate under the action of a spring 44 so that the end 42 of the lever 41 engages the aperture 43. The blades are physically separated by the ducts on the lever members 18 and are electrically insulated by spacers 29 mounted on the rods 27, 28. In a modification, Fig. 3 (not shown), each blade 22 is formed with a downward projection facing a bar disposed between the contact bars 27, 28 so that after the initial pivoting on the rod 27, the blade 22 pivots on the bar before moving into engagement with the rod 28. A sixth blade 71, pivoted on the bail roller 31, is rocked out of contact with the spacing rod 27 into contact with the marking rod 28 to provide a start impulse for an associated mechanical or electronic distributer.

Title: Digital transmission method for coded video signals
IPC: H04N7/56
Filed: 1976-06-22
Abstract: 1508555 Television DE TELECOMMUNICATIONS SA 22 June 1976 [3 July 1975] 25815/76 Heading H4F A method for the digital transmission of coded video signals wherein each line of the video signal comprises a line synchronization word multiplexed during the line fly-back period, comprising using as the line synchronization word a pseudorandom sequence the self-correlation function of which is such that the synchronization word can be detected at the receiving equipment within a window of at least 3 binary digits, and stuffing lines of the video signal by adding or subtracting one binary digit during the line fly-back period at a fixed location in relation to the line synchronization word. The analogue video signal is coded by means of an encoder, e.g. a differential PCM encoder, then multiplexed at 3 with the line and frame sychronization words generated at 2, devices 2 and 3 being regulated at a clock rate H E . Device 2 generates at the lline frequency a 15 bit-synchronization word constituting the line synchronization word, followed by one bit for the frame synchronization during the first 127 lines of the frame and by "0" bit during the remaining lines. A pulse stuffing device 4 adapts the signal digit rate to the transmission rate fixed by a clock H T . At the receiving equipment, the line synchronization word is investigated in a synchronization detector 5 having stored therein the 15 bit word. On starting it is considered that synchronization is found when 15 coincidences are counted, the system then being locked by device 6. Synchronization is thereafter investigated with a 3 bit-window centred on the expected location of the synchronization word. The pulse stuffing is extracted in device 7 and the clock rate HE is restored by multiplication and filtering of the synchronizing word frequency in a device 8. The frame synchronizing binary digit is detected at 9 after the line synchronization has been locked.

Abstract: 502,972. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., FURNIVAL, J. M., WITT, B. J., and COCKERELL, C. S. Sept. 28, 1937, No. 26282. [Class 40 (v)] In an equi-signal radio beacon comprising a plurality of aerials, the radiation of any horizontally-polarized component along the equisignal line is prevented by arranging the aerials parallel to this line. This eliminates the production of false equi-signal indications at the receiver due to the horizontally-polarized components of the transmitted radiation being -picked up by horizontal components of the receiving aerial. In Fig. 1, the equi-signal line E is produced by the two aerials A, A<1> and a horizontal component is radiated from the horizontal portions ab, a<1>b<1>, cd ... e<1>f<1>. This component is eliminated in Fig. 2 by arranging the aerials A1, A2, A1<1>, A2<1> parallel to the equi-signal line E, and the overlapping characteristics are obtained by setting back the aerials A1, A1<1> relative to the aerials A2, A2<1>. In a modification comprising three aerials parallel to the equi-signal line, the centre aerial is continuously energized and the two outer aerials, which are set back relative to the centre aerial, are energized alternately in dot-dash sequence. Alternatively, two directly - fed parallel aerials may be used, "slewing" of the beams being effected by suitable phase adjustment.
