Title: Improvements in or relating to doppler radar apparatus
Inventor: ROBINS WILFRED PERCY
IPC: G01S13/58
Filed: 1961-08-30
Abstract: 1,017,236. Doppler radar. GENERAL ELECTRIC CO. Ltd. Aug. 28, 1962 [Aug. 30, 1961], No. 31279/61. Heading H4D. In a Doppler radar system wherein sinusoidally frequency modulated continuous wavesignals are transmitted, a beat IF signal is produced by mixing the received echo signal with a signal obtained by offsetting the transmitted signal, and the upper and lower first order sidebands are separated out from the IF signal, whereby the amplitude of the sidebands varies as a first order Beseal function of the target range to give minimum system sensitivity to leakage signals and interference signals from zero range targets, the side bands are combined to produce a compound signal from which the Doppler signal can be obtained and one sideband is phase-shifted with respect to the other prior to the combination, whereby the range at which the sensitivity of the system is a maximum can be controlled. In the system shown, oscillator 4 produces a signal centred at X mc/s. and frequency modulated at 100 kc/s. by the output of oscillator 5. The modulated signals fed to aerial 3 for transmission, via circulator 6. The echo signal is mixed in mixer 11 with a portion of the transmission signal offset by 40 mc/s. by means of oscillator 12 (40 mc/s.) and mixer 13. The resultant beat signal centred on 40 mc/s. is further reduced in frequency in mixer 15 by means of mixer 17, oscillator 12 and oscillator 16 (2 mc/s.), such that it is centred about 2 mc/s. Band-pass filters 23 and 24 respectively separate out the sidebands spaced from the centre frequency of 2 mc/s. by plus and minus the modulation frequency, i.e. those centred at 2 mc/s. + 100 kc/s. and 2 mc/s. - 100 kc/s. Each sideband comprises two frequencies separated from the centre frequency by plus and minus the Doppler frequency, and having amplitudes varying as indicated above. Each sideband is amplified and converted to a common centre frequency of 550 kc/s. in mixers 27 and 28 with the aid of mixers 30, 31 and 33, frequency double 32 (200 kc/s.) and oscillator 29 (450 kc/s.). The signal from mixer 28 is applied directly to amplifier 35, while that from mixer 27 is applied to the amplifier via phase shifter 34. The output of the amplifier, comprising the combined outputs of the mixers, is fed to receiver stages 36, where the Doppler frequency is extracted and the speed of the target determined. Means for cancelling out transmitter energy leaking through circulator 6 to output 10, similar to that shown in Specification 916,486, are described.

Filed: 1934-11-01
Abstract: 443,449. Compound sheet materials ; loading paper pulp. SOC. OF CHEMICAL INDUSTRY IN BASLE, Basle, Switzerland. Nov. 1, 1934, No. 31377. Convention date, June 7. [Classes 96 and 140] [See also Group XV] Compressed, composite sheet material having an opaque, decorated surface is obtained by decorating an opaque paper having incorporated therein pigment, e.g. 10-40 per cent by weight, sufficient to render the paper opaque in the finished product, impregnating the decorated paper with a binding agent and uniting with a support by hot pressing, prefer. ably after drying. The paper may be made by incorporating the pigment, e.g. lithopone or zinc oxide, in the beater, and should not be strongly calendered. The paper, which may be coloured, is decorated with the desired design, lettering, &c. by drawing, painting, spraying, or printing. Binding-agents may include natural or artificial resins or cellulose derivatives, e.g. styrene resins, vinyl resins, shellac, cellulose nitrate or acetate, phenol or carbamide resins. Supports may include paper or fabric impregnated with resin, or wood, cork or artificial stone. In examples : (1) a decorated paper containing about 30 per cent lithopone is impregnated with carbamide-formaldehyde resin and after drying is made up into a pack with an unprinted impregnated paper and interposed sheets of cheap paper varnished with a similar resin, the whole being united by pressure and heat ; (2) a similar decorated paper is impregnated with a styrene resin and united to an asbestos-cement plate previously sprayed with the resin ; (3-5) products similar to that of example 2 are obtained employing cellulose acetate or phenol-formaldehyde, or by applying a paper sheet impregnated with shellac to an asbestos-cement plate coated with casein; (6) a decorated, opaque, paper sheet impregnated with carbamide-formaldehyde or styrene resin is united to a support of asbestos pasteboard, wood veneer and newspaper, or felted maize or sugar cane fibre, or is pressed on to a thick, sparingly-absorbent typewriting paper to furnish a sheet which may be glued to a suitable support. The paper for example 1 is prepared by grinding 100 kg. of lithopone, containing 60 per cent zinc sulphide, in a roller mill with 50 litres of water and introducing together with 200 kg. of alpha-cellulose into a beater, the formed paper being uncalendered or calendered only to a slight extent. The paper of example 6 is prepared by introducing 480 kg. bleached sulphite cellulose and adding, through a double filter, a suspension of 190 kg. lithopone in water.
Patent GB-426741-A (GB)
Title: Improvements in and relating to the preparation and purification of nickel carbonyl
IPC: C01G53/02
Filed: 1933-11-11
Abstract: Nickel carbonyl is separated in the liquid phase from a mixture of gases or vapours including carbon monoxide and nickel carbonyl by condensation at such a partial pressure of carbon monoxide in the condensation vessel that the vapour pressure of the nickel carbonyl is in the neighbourhood of the minimum for the condensation temperature.  The concentration of carbon monoxide may be varied to give the desired partial pressure, or the pressure at which the carbonyl is formed may be raised or lowered to the optimum value and condensation effected at this pressure. Where the carbonyl has been formed at this optimum pressure, no adjustment will be necessary. For condensation temperatures of 0-40 DEG  C., a partial pressure of 10--150 atm. gives good results. Preferably, the carbonyl vapour pressure is not greater than corresponds to 50 g. Ni per cubic metre of gas at N.T.P. above the minimum.  Between 0--80 DEG  C. the partial pressure of CO should be between 45 atm. less and 75 atm. more than corresponds to the minimum carbonyl vapour pressure. According to examples: (1) Gases from an atmospheric pressure nickel extraction plant containing nickel carbonyl equivalent to 420 g. Ni per c.m., are compressed at 0 DEG  C. to 55 atm. and separation then effected.  (2) Gases from a high pressure plant containing carbonyl equivalent to 450 g. Ni per c.m. at 250 atm. and 80 DEG  C. are expanded to 70 atm. at atmospheric temperature and separation then effected.

Abstract: 1420805 Muting circuits BRAUN AG 3 July 1973 31738/73 Heading H3T In a muting arrangement for a frequency modulation receiver, the audio channel is only unblocked when a signal dependent upon the presence of a signal carrier is present and a signal dependent on noise is absent. I.F. amplifier 1, Fig. 1, is connected via demodulator 2 to audio amplifier 3: a signal R amplitudemodulated by noise is taken from an I.F. amplifier 1, followed by a rectifier feeding amplifier R1 and rectified by rectifier R2. The output from rectifier R1 controls a digitizing device R3 giving an output 0 or I according to the absence or presence of noise. A further signal F is taken from I.F. amplifier 1 and rectified by rectifier F2 to control digitizing device F3 giving an output 0 or 1 according to the absence or presence of a signal carrier. The outputs from devices R3, F3 are applied to a gate M which develops an output 1 only when device F3 gives output 1 and device R3 an output 0: the output from gate M controls the unblocking of audio amplifier 3. In a second embodiment, the noise modulated signal R, Fig. 2, and carrier signal F are applied to two voltage-doubling rectifier circuits comprising diodes M11, M12 and M21, M22 respectively, the outputs of which are combined in series opposition to operate digitizer D, the output from which comprises the muting control. In a third embodiment a single output is taken from I.F. amplifier 1, Fig. 3, and rectified by rectifier R111: the output is amplified by D.C. amplifier R112 and applied to transistor T. Across resistor M3 in the emitter circuit of transistor T a D.C. voltage dependent upon carrier signal level is produced: the noise signal is passed from the collector circuit by means of a capacitor to voltage-doubler rectifier M11, M12 which produces a D.C. voltage across resistor M1 which is combined with the other D.C. voltage for application to the digitizer D controlling muting.

Abstract: 265,740. Kuyser, J. A., and Metropolitan-Vickers Electrical Co., Ltd. Dec. 17, 1925. Cores.-To resist the tendency of the conducbor insulation to swell in the transverse ventilating ducts of a dynamo-electric machine core, the slot walls are made continuous at the duct without the famine being bridged except at the ducts. In Figs. 1 and 2, a ventilating duct is shown bounded by plates 11, 15. These plates, referred to as vent plates, are of stouter construction than the usual core laminµ. The slot 13 is continued across the duct by means of a bridge piece 12 of channel section, spot-welded at 14 to the vent plate 11. A bridge piece formed of two parts of channel section may be employed, one part being welded to the plate 11 and the other to the plate 15. Instead of the bridge piece being made continuous around the slot, three separate pieces may be provided for the two sides and the bottom. The slots in the vent plates may be slightly larger than the slots in the laminµ so as to allow for filing or drifting the core to correct slight inaccuracies in manufacture. In order to allow for adjustment during the assembling of the core, for example by drifting, the flange 29 of the bridge piece, Figs. 6 and 7, may be formed with slots 30 and is spot welded to the vent plate at 31 so that the web 32 may be drifted to bring it flush with the slot wall.
