Filed: 1969-11-24
Abstract: 1277936 Non-consumable arc electrodes WESTINGHOUSE ELECTRIC CORP 24 Nov 1969 [17 Dec 1968] 57377/69 Heading H5H An arc furnace electrode comprises a non- consumable annular electrode tip 10, a supporting Column-31, 32, 33, for the tip 10, and a heat shield enclosing a major portion of the supporting column, the heat shield being in the form of a metallic structure e.g. 11, 12, 13 &c. electrically insulated from the tip 10 and column 31, 32, 33 and being spaced from the column to provide a passage 44 for coolant to flow between the shield and the column. As shown, the heat shield comprises a plurality of metal segments 11-21, mutually insulated by intervening thin mica rings 26, and urged together to compress seals 23 by means of a screw clamp member (not shown) secured to the supporting column, a BELLVILLE washer (not shown) being provided to allow for thermal expansion of the metal segments 11-21. The segments of the heat shield may be biased at a potential other than the tip potential to obviate arcing to the melt and in this instance the insulating rings 26 between the metal segments may be omitted except for the two at the top and bottom of the stack. The supporting column comprises three concentric metal tubes 31, 32, 32, a coolant (water) outlet passage 124 being formed between tubes 32, 33 and a coolant inlet passage 40 being formed between tubes 31, 32. In the inlet passage are situated insulated conduits 35, 36 for current supply to a field coil 84 which rotates the arc root around the annular arc surface 61. Coolant flows through passage 40, overflows into passage 44 passes through peripheral gaps 52 in tube 31 to a U-section annular passage 60 surrounding the arcing surface 61 and thence to outlet 124. The field coil 84 is also hollow and supplied with coolant through its conduits e.g. 35, 36. A central passageway 82 is provided for supplying material to the electrode tip 65. Instead of mica spacers 26, the segments 11-21 may be sprayed with a ceramic coating. Where thermal insulation would not impair operation of the furnace the outer surfaces of the segments may be coated with a good thermal insulator e.g. alumina.

Abstract: 1370950 Sintering iron powders AGENCY of INDUSTRIAL SCIENCE & TECHNOLOGY 15 Dec 1972 [21 Dec 1971 28 Dec 1971 3 April 1972] 58110/72 Heading C7D [Also in Division H1] The negative plate of an alkaline storage battery (see Division H1) is produced by sintering needle-shaped particles of ferric oxyhydroxide, Fe.OOH, or gamma-ferric oxide, Fe 2 O 3  at between 500 and 1000C in a hydrogen at mosphere, pulverizing the resulting sintered iron body into particles smaller than a predetermined size, tamping the particles into a mould, and sintering in hydrogen at a higher temperature than the first stage, between 700 and 1050C.

Filed: 1968-12-09
Abstract: 1,252,266. Digital transmission systems. KOKUSAI DENSHIN DENWA K.K. 9 Dec., 1968 [8 Dec., 1967], No. 58388/68. Headings H4L and H4P. A demodulator for a phase-shift modulated signal comprises a circuit 2, Fig. 2, which samples the signal at a frequency much higher than that of the carrier and provides digital signal samples representing the amplitude of the carrier at the sample instants, these samples passing to a counter 3.1. The counter output passes to a circuit 6 and to a delay 4 which returns the counter output to the input after a delay equal to n times the time between successive sampling pulses. The counter adds or subtracts its two inputs under the control of a circuit 3.2 which is fed by a signal representing the sign of the present sample and the sign of the instantaneous amplitude of a reference carrier signal phase-locked to the received carrier. The output circuit stores the sign of the counter output at the end of each received signal element. The demodulator may receive one or more 2<SP>n</SP>- phase phase-modulated signals, each such signal representing n binary data channels. In Fig. 3, for example, where n = 2, the received signal at 1 is sampled at 2.1.1 by pulses from generator 13. Sampling is inhibited near the signal element transitions by gate 9, controlled by element-rate clock pulses synchronized with the received signal elements at 1. The samples are converted to parallel form and passed to control circuit 3.2 which is also fed with a signal from gates 5.4b, 5.4a, enabled alternately at the sampling rate and fed by a reference carrier frequency from 5.1 directly and via a 90 degree phase shifter respectively. Delay 4.1 has a period of twice the sampling pulse period. At the end of each element period, when no sampling is occurring, pulses from gates 16a, 16b cause registers 6a, 6b to store the sign bits of the respective signals circulating in the counter-delay loop, representing the data on the 2 binary channels. In another embodiment, Fig. 4 (not shown), eight phase-shift signals are demodulated in a circuit similar to Fig. 3 but employing eight pairs of reference carriers in time-division multiplex manner. In a modification of Fig. 3, where n= 3, the four circulating sign bits from the counter 3.1 are fed to respective registers, whose outputs are used to derive the binary data on the three channels, Fig. 7 (not shown). If the signal received is in differential form and n =2, Fig. 3 is modified by the insertion of a modulator, controlled by the registers' output, following the reference carrier generator 5.1, Fig. 8 (not shown).
