Title: Improvements in or relating to multiplex telegraph systems
IPC: H04L13/14
Filed: 1933-04-12
Abstract: 412,732. Diplex telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Mathes, R. E. ; 755, Belvidere Avenue, Westfield, New Jersey, U.S.A.) April 12, 1933, No. 10962. Convention date, April 13, 1932. [Classes 40 (iii) and 40 (v).] In a diplex line or wireless telegraph system using morse or like code characters of unequal length, the first half of each dot period is allotted to one channel and the second half to the other. Two automatic transmitters feed an aerial through a distributer which allocates the line time accordingly (Figs. 1, 2, not shown). At the receiver the block signals a are rectified by the valve 20 as at b and produce pulses as at c through a valve 25 and shaping and delay circuit 22, 23, to synchronize the multi-vibrator which produces continuous impulses as at d. These impulses are applied to valves 26, 27 of the first channel through condensers which shape them into pulses as shown at h, f. The valve 26 is biassed as at h to respond to the pulses so that, in the absence of marking signals, it takes control of the flip-flop device 28, and spacing polarity is consequently applied as at j2, j4 to the receiving-apparatus R of the first channel. The valve 27, on the other hand, receives the combined effects g of the vibrator pulses f from the conductor 37 and signals c from the valve 29, and is biassed as at f so that it cannot respond to vibrator pulses f alone or to signal impulses c alone, but can respond to combinations such as gl, g3, of these two. The circuit constants are such that the received signals paralyze valve 25 and so act upon the grid of valve 27 by removing the negative voltage-drop from resistance 30 upon blockage of valve 29. When valve 27 responds it overpowers the effect of the valve 26 and takes control of the flip-flop 28, so that a marking signal is sent to the apparatus R ; and since the impulses f, h are so timed that the apparatus is receptive during only the first half of each dot period, the signals at R are prolonged to full length as at j. Inductance 23 delays the pulses c so as to give the signals time to attain a steady state. The second channel is fed through the leads 38, 39, and is receptive during the second half of each dot period under the control of the same multi-vibrator 35.

Title: Number squaring apparatus
IPC: G06F7/552
Filed: 1972-03-09
Abstract: 1390052 Squaring binary numbers E I DU PONT DE NEMOURS & CO 9 March 1972 [10 March 1971] 11106/72 Heading G4A An apparatus for squaring a binary number operating on the principle (2S)<SP>2</SP>=4S<SP>2</SP> and (2S + 1)<SP>2</SP> = 4S<SP>2</SP> + 4S + 1 is arranged for successive (controlling) bits of the number in descending order of significance to perform one of the two following operations in accordance with the value of the controlling bit, namely, when the bit is "1", to add the number formed by the higher ordered bits of the number (zero in the case where the current controlling bit is the most significant bit), to the result of the operation performed for the preceding, next higher ordered, controlling bit (zero where the current controlling bit is the most significant bit), to shift the result two places to higher order, and to fill the thus vacated least and next least significant bit places of the result with "1" and, "0" respectively, and when the controlling bit is "0", to shift the result of the operation performed for the preceding, next higher ordered, controlling bit two places to higher order, and to fill the thus vacated least and next least significant bit places of the result with "00" the final result being the square of the number. As described, the number to be squared is presented serially at input 13 and is clocked into register 19, the value of the current bit controlling, via NOR gates 21-24, the addition of the contents of register 19, i.e. the bits of the number to be squared of higher order than the current bit, into the result register 20, the interconnections between adder 25 (which is conventional) and register 20 providing the two place shift to higher order when the output of the adder and the current bit are clocked into register 20, and the current bit is clocked into register 19. A further addition of the new contents of registers 19 and 20 then occurs under the control of the new current bit now available at input 13.. The flip-flops 20a-20h form seven of the eight bits of the result, the remaining second least significant bit being permanently zero (see above). The final result may be extracted in parallel from register 20, or by means of gates 31, 33, 34 and a clock signal, serially at 35. The Specification, gives brief details of possible modifications, e.g. the number to be squared is initially loaded in parallel into a four bit register, a controlling network being used to gate the required bits to an adder. The adder outputs may supply the sum bits to the corresponding or corresponding plus one bit locations followed by two and one place shifts respectively. The system may be modified to deal with numbers having greater numbers of bits. The arrangement is said to be of use in mass spectrometry and other applications where squares have to be calculated.

Abstract: 1,221,075. Cathode heaters. VARIAN ASSOCIATES. 7 March, 1968 [7 March, 1967], No. 11230/68. Heading HID. In a method of making a cathode heater for use in an electron tube, the surface of a tungsten or molybdenum wire is roughened and darkened by oxidizing the surface and then substantially blackening it by reducing it to its metallic state. To oxidize the wire it may be heated in air for 5 minutes at 725‹ C. and the oxidized wire may be subsequently reduced by heating in wet hydrogen for 5 minutes at 1650‹ C. The heater may be further roughened and darkened by coating the oxidized wire with, for example, ammonium tungstate-this coating also being reduced subsequently to its metallic state. In a further example, the oxidized wire may first be coated with alumina and then with ammonium tungstate and the coated wire may then be heated in a reducing atmosphere for 10 minutes at 1000‹ C. to sinter the alumina coating to the wire and to reduce the oxide and ammonium tungstate to their metallic states.
