Patent GB-343920-A (GB)
Title: Improvements in or relating to cord circuit repeater arrangements for telephone systems
IPC: H04M3/40
Filed: 1929-11-25
Abstract: 343,920. Manual exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and GUBBINS, T. R., Columbia House, Aldwych, London. Nov. 25, 1929, No. 35977. [Class 40 (iv).] In a system in which incoming and outgoing junctions are multipled at the positions of line operators and of cord circuit repeater operators, an idle cord circuit repeater is selected under control of the line operator who answers the call. In the system described, a line operator wishing to associate a repeater with the call, replaces the ordinary back plug by the back plug BP of one of her special cords the front plug FP of which she inserts in the wanted line whereupon B starts the allotted finder FM (or alternatively all idle finders). If all the repeaters are busy RL is flashed, otherwise it glows when the amplifier is connected up. The operator then throws AN operating MN, to signal the repeater operator and make a connection over ROT to her talking key. On learning the numbers of the lines the repeater operator plugs into them and their artificial lines with the double plugs BL, BN, FL, FN. BS, FS transfer the lines from the ordinary jacks to the amplifier jacks. H, J operated in series with BS, FS actuate the repeater by grounding SC and energize L. Monitoring key MK connects the line operator's set to monitoring windings of the repeater. To talk to, or ring either line the operator throws her talking key TH or one of the ringing keys RK and splitting key SK in one or other direction energizing E, F which release BS, FS but hold H, J, and short circuit the input to the repeater to prevent singing. Ringing tone is connected up by the keys RK. If ringing current is received during the time the repeater is connected up, DR or CR releases L and K energizes G which locks and lights CL. If the ringing current is received while TK is thrown CL is lit directly by BR or FR which lock up. When the cord is taken down B removes ground from wiper 8 and the finder goes home. FL glows and the repeater operator takes down the amplifier cord.

Title: Improvements in the manufacture of magnetic alloys
IPC: C22F1/10
Filed: 1933-12-21
Abstract: In the manufacture of magnetic nickel-iron alloys containing 30-90 per cent of nickel to which has been added at least one element of low solid solubility, e.g. silver, beryllium, antimony, magnesium, calcium and copper, the alloys are annealed at a temperature of 900 DEG  C., or over to form a homogeneous solid solution, cooled from that temperature sufficiently rapidly to obtain a state of super-saturation of the added element or elements in solid solution, subjected to an amount of cold working sufficient to reduce them to their final size, e.g. a reduction of thickness of from 10-90 per cent, and then soaking the alloys at p  a temperature in excess of 250 DEG  C., but below 500 DEG  C., for a period of time sufficient to produce a precipitation of some of the added element or elements. One or more freely soluble resistance elements such as chromium, molybdenum, manganese, tungsten, aluminium, silicon, vanadium and cobalt may be added to the alloys.  Copper may act as a precipitating element or as a freely soluble element especially when one of the other freely soluble elements is present; the capacity of the solute for the copper decreasing in proportion to the amount of iron present and also to the presence of the freely soluble elements.  In an example, 98,5 parts of an alloy containing 40 parts of nickel, 60 of iron, 0,5 of manganese and 1,5 of chromium was melted with 1,5 parts of silver and the alloy cast.  The casting was hot forged, annealed at 1100 DEG  C., for 30 minutes, cold rolled without intermediate annealings down to 0,01 inch strips and sheared.  The cold rolled strip was then soaked for 2 hours at 300 DEG  C.  Specifications 357,947 and 386,682 are referred to.

Title: System for Transmitting or Recording and Reproducing a Plurality of Signals
IPC: H04N9/86
Filed: 1966-10-03
Abstract: 1,168,077. Television; multiple pulse systems. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 3 Oct., 1966 [18 Jan., 1966; 15 Feb., 1966 (2)], No. 36476/68. Addition to 1,168,076. Headings H4F and H4L. Relates to a modulation and demodulation system for modulating two signals in one channel, e.g. the I and Q chrominance components in an N.T.S.C. or PAL type colour television signal or the alternating colour difference chrominance components in a line sequential colour television system, and to the use thereof in recording a composite colour television signal on a magnetic tape to avoid the beat which otherwise occurs between the colour subcarrier and the frequency modulated carrier of the magnetic recorder. The modulation system comprises an astable multivibrator 53, Fig. 11, and a mono-stable multivibrator 56. The output of the astable multivibrator is frequency modulated or pulse width modulated by a modulation signal A to derive waveform (a), Fig. 8, and the leading (rising) edge (b) (or trailing edge) of this waveform is pulse width modulated by the second modulation signal B in the mono-stable multivibrator to derive waveform (c); i.e. one of the positive or negative going zero cross-over points of a rectangular pulse waveform which has previously been frequency modulated or pulse width modulated by a first signal, is pulse-width modulated by a second signal. To demodulate this signal it is first differentiated 48, Fig. 9, and the resulting positive and negative pulses are respectively demodulated according to the respective modulation systems by demodulators 49 and 50, signal A which has been frequency modulated or pulse width modulated being derived from 49 and the sum of signal A (which has been frequency modulated or pulse width modulated) and the signal B (which has been pulse width modulated) is derived from 50. Signal B is derived by means of inverter and matrix circuits 51 and 52. The modulation system may be used to modulate the two chrominance components, e.g. I and Q, or R and B which are to be recorded in one channel of a magnetic tape recorder, the luminance or G signal being frequency modulated on a carrier and recorded in a second channel of the recorder. If a onechannel magnetic recording apparatus is used, the luminance (including the horizontal synchronizing signals) and chrominance signals thus modulated are sequentially switched at line frequency to the magnetic recording head (or heads) the reproduced signals being alternately delayed to produce a continuous colour television signal.
