Title: Receiver for a radio navigation system
IPC: G01S1/68
Filed: 1976-03-12
Abstract: 1513991 Radio navigation RAYTHEON CO 12 March 1976 [31 March 1975] 10032/76 Heading H4D The invention relates to a receiver for use in a radio navigation system of the type in which a plurality of beacons, e.g. on buoys, radiate radio signals distinguished both by their carrier frequencies and by signals modulated on to the carrier frequencies. For example, each buoy transmitter operates on a unique predetermined carrier frequency modulated with two or more audio tone signals, the combination of which uniquely identifies the buoy, Fig. 5 (not shown), or modulated with a unique digital code signal, Fig. 7 (not shown). The receiver, Fig. 2, has a search mode and a direction-finding mode, with switches 205, 225, mechanically ganged together for manual switching from one mode to the other when a signal acquired light 234 is lit. The RF signals received by omnidirectional antenna 201 are amplified and mixed with the output from a voltage controlled oscillator 229 by mixer 203, the IF signals passing through IF filter 204 to amplitude modulation detector 209. The output frequency of oscillator 229 is controlled via signals from a clock generator 223, a counter 226 for counting the clock pulses. and a digital/analogue converter 227 converting the count to an analogue voltage. When the desired signal from a buoy is received it is locked in by halting the counter 226, light 234 is lit and switches 205, 225, operated to couple in directional antenna 200, which is rotated until a null in amplitude of received signal strength is located. The audio signals from tunable filters 210,211, are summed at 215, amplified in 217 and passed to loud speaker 218 to assist in this operation. A second indication is given by a null meter 241. Once the direction and identification of a buoy is completed, the process is is repeated for a second buoy and the ship's position computed by triangulation. An alternative receiver, Fig. 4 (not shown), replaces the filters 210, 211, and detectors 212, 213, by means whereby the digital code of the designated buoy is operator selected by switches and loaded into a code store for comparison with the output of a shift register into which the received signal is loaded, the comparator output stopping the scanning operation when the desired signal is received.

Title: Improved process of producing copper sulfate
IPC: C01G3/10
Filed: 1933-04-06
Abstract: Copper sulphate is obtained by treating copper oxychloride or substances producing it in situ with sulphur dioxide or gases containing it.  (1) In the direct treatment of copper oxychloride, this is suspended in cupric chloride solution so that there is a preferred Cuo--Cucl2 ratio of about 2 : 1, and treated with sulphur dioxide while being sprayed into a chamber or passed down a tower packed with coke, pumice, ceramic rings, &c.  The gases may also be blown into the fluid mixture. By use of a suitably concentrated initial suspension and operating at 70--80 DEG  C., copper sulphate may by crystallized directly from the hot solution after removal of cuprous chloride.  The latter is mixed with cupric chloride solution of sp. gr. 1.2 and oxidized to copper oxychloride in a tower by air, if desired at 100 DEG  C. Alternatively, the suspension is sprayed into a chamber with superheated steam and hot compressed air, or the cuprous chloride is oxidized in thin layers on plates.  Excess cupric chloride is separated and converted with copper to cuprous chloride which is oxidized to copper oxychloride.  This, with that obtained above, is returned to the cycle.  (2) In a modification, cuprous chloride is suspended in cupric chloride solution and circulated through a tower, being treated simultaneously or alternately with hot air and sulphur dioxide obtained, say, by roasting pyrites.  (3) In a second modification, cupric chloride solution is passed down a tower packed with copper wire, shavings, &c., and treated simultaneously or successively with hot air and sulphur dioxide gases.  The presence of sulphur trioxide in the roaster gases is desirable.  Copper alloys may be employed, the copper being separated from the soluble metal salts as cuprous chloride or copper oxychloride.  Any silver present is obtained as chloride by dissolving the copper oxychloride in hydrochloric acid. Specification 323,115, [Class 1 (iii)], is referred to.

Title: Improvements in and relating to electric protective systems of the differential type
IPC: H02H3/28
Filed: 1942-07-24
Abstract: 558,304. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 24, 1942, No. 10348. Convention date, July 25, 1941. [Class 38 (v)] A differential protective system immune from operation by inequalities due to currenttransformer saturation on through-faults, has the restraining winding of the relay energized by the product of the incoming and outgoing currents, whereby the restraint is caused to disappear, or to reverse and so assist the operating winding, on internal faults. By thus ensuring correct operation on internal faults, the usual saturation of the operating winding can begin at full-load current, and a steeper slope of the relay characteristic curve at higher values of through-current obtained, Fig. 2 (not shown). In Fig. 1, difference-current ID is fed either through a saturable transformer 30, or direct to the saturable operating winding 29, of a beam or induction disc relay, the restraining windings 37, 38 of which are fed by the currents I 1 , I 2 , respectively, so as to provide a restraint which is proportional to their product and accordingly reverses when both ends feed an internal fault. To prevent operation by magnetizing inrushes into transformer 10, winding 29 is shunted by a resistance 35 which, after the transcience-period, is disconnected by a voltage relay 33. In Fig. 3, a line 40 is protected by a relay of the construction described in Specification 508,004, comprising a stator having eight salient poles 54 ... 61 energized by currents -I1, ID, -I2, -I1, I2, 11, I2, ID, respectively. Poles 54, 55, 56, 60, 61 provide an operating torque and poles 56 ... 60 a restraining torque. The Specification also refers to a form in which separate operating and restraining relays with series connected contacts are provided, and to one in which the resultant torque due to three elements equals (I1+I2) -I1<SP>2</SP> -I2<SP>2</SP>, or I1 I2.
