Title: Improvements relating to a transmission line section
IPC: H04B3/10
Filed: 1965-11-25
Abstract: 1,109,566. Repeater systems. CIT-COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 25 Nov., 1965 [26 Nov., 1964], No. 50230/65. Heading H4R. Pilot-operated automatic volume control and faulty repeater locating system utilizes, for regulation of each section between adjacent repeaters a different pilot frequency, the frequencies of adjacent sections differing by the same value so that the pilot frequency varies in arithmetical progression along the line. All the pilot frequencies are received at the terminal station to be detected and used to locate a faulty repeater. Fig. 2 shows a typical repeater amplifier A<SP>1</SP>m of a system, the output of the amplifier being mixed in T<SP>1</SP>m with the pilot frequency F m  for the succeeding repeater section. In addition the locally generated pilot frequency F m  is used to modulate the repeater amplifier output which includes the pilot frequency F m -f, of the preceding section. The difference frequency f, e.g. 1000 c/s., which will be the same in all repeaters of the system, is extracted by filter 2, rectified, compared with a reference V o  and the difference used to control the gain of the amplifier A<SP>1</SP> m . In a two-way system, Fig. 1 (not shown), the pilot frequencies along the direction of transmission in one channel are arranged to increase, while in the direction of transmission in the other channel they decrease and the same pilot frequency generator is used at each repeater station for both directions of transmission. At the terminal station a main pilot may be extracted to provide overall compensation of the line, while all the individual repeater section pilots are monitored to provide fault location. The repeaters may include transistor amplifiers.

Inventor: MCCONNELL ROBERT G
IPC: G03G15/10
Filed: 1969-10-29
Abstract: 1276749 Electrostatic recording mirror galvanometer HONEYWELL Inc 29 Oct 1969 [31 Oct 1968(3)] 52868/69 Heading G1J [Also in Division G2] A recording mirror galvanometer, in which a signal may be recorded on ordinary photographic paper, is converted for electrophotographic recording by the addition of a charging unit and a liquid development unit comprising a container having a bottom opening covered by a permeable membrane. Light from lamp 32 is focused upon mirrors 34 of a plurality of galvanometers 30 to which a signal is applied to accordingly reflect a beam to a recording paper either via pivotable mirror 75 for normal photographic recording or via mirror 36 for electrophotographic recording. In the latter case photo-conductive paper 12 is fed from roll 14 by a variable speed drive past charger 20 and the exposure station to a liquid developer applicator 42 comprising a container 46 of a suspension of toner particles, charged oppositely to paper 12, in an insulative liquid. The bottom of container 46 contacts sheet 12 and is formed by a curvilinear screen 48 covered on the inside by a permeable membrane 50 which may be of felt, wool &c. Membrane 50 is thin enough to allow transfer of liquid at the fastest speed of paper 12 but is thick enough to prevent leakage when the recording paper 12 is stopped. With the toner so charged it is stated that particles adhere only to the areas of charge gradient at the edges of the lines produced by relative movement of the light spot and the paper 12. Longitudinal grid lines may be recorded using grid filter 61, mirror 59 and lens 60 and timing marks may be recorded being pulses from flash-tube 74. To compensate for different paper speeds through charger 20 which results in different charge densities on sheet 12, the sheet may be uniformly illuminated by another lamp to dissipate some of the charge on the sheet, the amount depending on the paper speed. In a second embodiment Fig. 5 (not shown) the same optical elements are used for the two recording methods.

Abstract: 1450090 Valves TELDIX GmbH 22 Nov 1973 [22 Nov 1972 8 March 1973 22 Aug 1973] 54284/73 Heading F2V [Also in Division G3] A valve comprises two closure members 4<SP>1</SP>, 5<SP>1</SP> for controlling communication between ports 8<SP>1</SP>, 6<SP>1</SP> respectively and a port 7<SP>1</SP>, which members are connected with lost motion to an operative member 3<SP>1</SP> which in a first position holds member 4<SP>1</SP> against its seat to close port 8<SP>1</SP> and allows communication between ports 6<SP>1</SP> and 7<SP>1</SP>, in a second position closes port 61 and allows communication between ports 8<SP>1</SP> and 7<SP>1</SP> and in an intermediate position closes ports 6<SP>1</SP> and 8<SP>1</SP>. The first position is normally held by a spring 9<SP>1</SP>. Actuation to the other positions is by an electromagnet 2<SP>1</SP> which requires currents of different values to achieve the two positions. This is because from first to intermediate position the member 3<SP>1</SP> moves against spring 9<SP>1</SP>, but from intermediate to second position moves against spring 9<SP>1</SP> and a spring 17<SP>1</SP>. The spring 17<SP>1</SP> may be dispensed with and the different forces achieved by spring 10<SP>1</SP> acting against spring 9<SP>1</SP> for the first move and spring 9<SP>1</SP> alone for the second move. Instead of using different current values to actuate the electromagnet an electronic circuit is described which achieves the same actuation through a pulsing system which requires two inputs for the two different positions. Circuits are also described which monitor the intermediate position by voltage comparator, electric switch, and magnetic field measuring methods.

Abstract: 1326103 Cathode-ray tube displays INTERNATIONAL BUSINESS MACHINES CORP 16 Nov 1970 [21 Nov 1969(3)] 54355/70 Heading H4T A CRT display arrangement for alphanumeric data employs a multiplexing arrangement for storing character signals for the different displays of a number of CRT's. Data in the form of 6-bit bytes each representing a character is received on line 206 and transferred in parallel into four delay-line buffer elements 312, &c., each element holding 64 characters corresponding to a row of a CRT display and handling data for eight of the thirty-two independent displays, since when the data for one display is shifted down to the next line buffer it is replaced by data for the next display of the eight. Five buffers are provided, allowing the characters to be decoded five times into video bright-up signals for five lines of one of two interlaced fields, the display being a 10 Î 8 brightened dot matrix with a six-line space between rows of characters. Thus from any given line-buffer element an output is obtained which successively represents the 64 characters to be displayed on eight different display units, the output being 6 bits in parallel for each character in series. The rasters of the eight different display units in a group are started at staggered times, as each starts to receive its set of 64 characters for a given row at successive line periods. After all 32 first rows of characters have been supplied to 310 the second rows are supplied similarly and this is repeated for the whole display of 10 rows of characters, subsequent alternate repetitions relating to alternate interlaced fields. The outputs from the line stores are supplied to character generators PCG 1-5 which also receive a field signal and generate the appropriate bright-up signals for each line of the video display, namely eight bits supplied in parallel and dynamicized in a multiplex video generator. The dynamicized outputs from the five generators are made available to all display CRT's, which also receive linecount signals used to demultiplex and gate the appropriate output for bright-up. Schematic circuits for the functional units are described and illustrated, and the modifications necessary to allow display of lower-case letters (extending below the 10 scan lines of upper case), and display in colour are described.
