Title: Method of directing a transmitting aerial towards a receiver
IPC: G01S1/12
Filed: 1971-06-22
Abstract: 1356202 Radio directional control; aerials PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 June 1971 [23 June 1970] 29199/71 Headings H4D and H4A In a system for automatically directing a transmitter aerial towards a receiver aerial, a direction controlling device coupled to the transmitter aerial is actuated by an error signal derived at, and sent from, the receiver. The transmitter aerial radiates a periodically recurring signal each period of which comprises a first sub-period containing a given type of information, and a second sub-period not containing said information. The transmitter aerial normally radiates in a main direction, but during first and second successive intervals of said second sub-period it radiates in respective first and second subsidiary directions, which are symmetrically disposed about said main direction. Means connected to the receiver aerial derives the error signal from the signals received during said first and second intervals. As described, the transmitter aerial is associated with a mobile television camera, while the receiving aerial is associated with a television van. The radio link between the camera and the van may operate at from 1 to 2 GHz, and the transmitter aerial comprise two spaced apart circularly polarized radiating elements and a phase shifting arrangement whereby the direction of radiation -may be changed by Œ10 degrees from broadside. The period is the field duration (e.g. 20 milli-seconds), and the second sub-period is the field blanking duration. The first and second successive intervals correspond to the durations (e.g., each about 64 micro-seconds) of successive line scans during field blanking. During transmission of the two chosen lines a constant grey level is introduced. A reception circuit comprises a video amplifier 50, Fig. 4, the output side of which is connected to a counting circuit 51 and, through respective diode switching bridges 57, 58, to capacitors 54, 55. A trigger pulse 51a is produced by the circuit 51 at the line pulse corresponding to the first interval and operates a monostable flip-flop 53 to open the bridge 58, so that the capacitor 55 charges. At the next line pulse a trigger pulse 51b operates-a flip-flop 52 to open the bridge 57, so that the capacitor 54 charges. The error signal is produced by a differential amplifier having inputs from said capacitors. In an alternative reception circuit for a frequency modulated system, the amplitude changes which occur when the transmitter is radiating in the subsidiary directions, during the first and second intervals, are utilized to open diode switching bridges connected to capacitors. As a precaution against false operation a monostable flipflop (44), Fig. 6 (not shown) inhibits a pulse selector (43) for a period slightly less than one field duration after each operation thereof.

Title: Improvements in or relating to decomposition of sulfide minerals
Inventor: HILL CYRIL THOMAS
IPC: C01G1/06
Filed: 1955-10-17
Abstract: Sulphur and metal chlorides are prepared by treating metal sulphides with a chlorinating agent at 100 DEG  to 440 DEG  C. in the presence of 2 to 1 parts by weight for each part of metal sulphide, of a liquid which is a solvent for the chlorinating agent.  Whilst sulphur is the preferred solvent, other liquids which dissolve the chlorination agent used or the chlorine liberated therefrom, may be employed.  The chlorinating agent may be free chlorine, sulphur chlorides or ferric chloride and the operation may be effected at atmospheric or super-atmospheric pressures.  As shown in the drawing, dried finely-ground sulphide is introduced into a reactor 4 through line 1 and is intimately mixed therein with liquid sulphur from line 3 and chlorine from line 2, the latter preferably being in less than the <PICT:0805922/III/1> stoichiometric proportion.  The products leave the reactor through line 5 as a suspension of metal chloride, unreacted sulphide and sulphur and pass to a settler 6 where a portion of liquid sulphur corresponding to that formed in reactor 4 is separated and withdrawn through line 7.  The bottoms from the separator 6, consisting of metal chlorides, unreacted sulphide and sulphur, pass through line 8 to a second reactor 9 where they are contacted with chlorine from line 10 to complete the decomposition of the sulphide.  The reaction products pass to a settler 12 where the ferrous chloride is withdrawn from the bottom and the excess sulphur containing sulphur chlorides is recycled through lines 13 and 3 to the first or second stage reactors 4 and 9.  The ferrous chloride may be converted to ferric chloride by known means or may be heated with air or oxygen to convert it to ferric oxide, thereby liberating chlorine which is recycled to the reactor 9. Alternatively the mixture of ferrous chloride and sulphur which is removed from the reactor 9 by line 11 is reacted with ferric chloride, thereby producing ferrous chloride and releasing sulphur chloride which may be recycled as a chlorinating agent.  The ferrous chloride after separation of the excess sulphur may be oxidized by air or oxygen to form ferric chloride, which is used to decompose further ferrous chloride, and iron oxide in an amount corresponding to the iron content of the ferrous chloride contained in the original ferrous chloride-sulphur mixture. According to an example, finely-ground pyrites was suspended in molten sulphur and at 349 DEG  C. chlorine was passed therethrough. 98 per cent of the metal sulphide was decomposed in about 2 hours whilst the temperature rose to 390 DEG C.  A further example relates to the use of sulphur dichloride as the chlorinating agent, the liquid sulphur solvent reacting with such dichloride to produce free chlorine.

Filed: 1924-12-10
Abstract: 226,204. Maatschappij van Berkel's Patent. Dec. 11, 1923, [Convention date]. Loose - weight apparatus. - A capacity-increasing device for weighing-apparatus comprises one or more weights which are pivotally mounted on a common axis of rotation coincident with that of the weigh-beam, said weights being adapted to be brought into a position in which they bear on a part of the weighing- mechanism. As shown, a weighing- platform 1 is supported on knife-edges 6 on the short arm 7 of a weigh-beam, which is pivoted on pedestals 10 and has its long arm divided into two parallel members 12, 13. A series of plate-shaped weights 22 are pivoted on a common knife-edge 24 projecting from one of the pedestals 10 and in alignment with the knife-edge 8 of the weigh-beam. Said weights 22 are adapted to bear at their free ends in recesses 31a in a cranked extension 15 of the weigh-beam, but are normally held out of contact with the extension 15 by means of a series of cranked levers 19 which are pivoted on a bolt 17 and are operated by a cam-member 30. The cam-member 30 is rotated by a hand wheel 25 to lower any desired number of the weights 22 on to the extension 15. When all the weights 22 have been lowered into operative position, a continued rotation of the hand wheel 25 causes the weights to be simultaneously lifted and a large weight 40 to be lowered into operative position on the other side of the machine, further rotation again causing the lowering of the small weights 22. The number of the weights in use is communicated through a flexible shaft 44 and pulleys 45 to indicating-discs 43. The weighing mechanism is relieved during the application of the weights by a wedge 47 which engages the short arm 7 of the weigh-beam unless the hand wheel is in a certain position.

Filed: 1955-10-18
Abstract: <PICT:0816792/III/1> <PICT:0816792/III/2> <PICT:0816792/III/3> A combined extracting and refining process for glyceride fats and oils, particularly cottonseed oil, which is suitable for batch or continuous operation, comprises converting the oil-soluble impurities contained in the source material to water-soluble impurities by treating the source material in the presence of any included moisture with a refining reagent such as urea, sodium carbonate, sodium bicarbonate, or sodium phosphates, or with small quantities of sodium hydroxide, all preferably in the solid state, as a result of which the impurities are deposited on the source material, and thereafter extracting the fat by passing a selective solvent for the fat, suitably n-hexane, through the mixture while the included moisture is present.  As shown, a preferred continuous embodiment comprises (Fig. 1) a screw conveyer 10 which supplies source material to a five-ring cooker 12, whence the material passes to salt feeder 28, where the material is mixed with the refining reagent fed in from hopper 29. The mixture then passes to press 16, where much of the oil is extracted by pressure and passes by line 17 to head tank 18 (Fig. 2). The source material from press 16 passes to flaking rolls 20, on which it is comminuted, and then to the top of extracting column 23, up which is flowed an extracting solvent supplied from tank 25.  The resulting miscella passes through filter 38 to head tank 39 (Fig. 2), while the extracted residue from the bottom of the extracting column is removed by conveyer 32 to drier 34.  The resulting meal is suitable as a cattle or poultry feed.  The oil in head tank 18 (Fig. 2) and the miscella in tank 39 then pass through a T-duct 52, which interconnects rotometers 43 and 51, to proportionometer 41, where the oil or miscella is mixed with caustic soda solution supplied from tank 54.  The mixture then passes to homogenizer 60, where the mixture is homogenized for 15-90 seconds with recycling under high pressure (usually more than 300 p.s.i.).  The mixture passes through heat-exchanger 70 to soap centrifuge 74 (Fig. 3), where soapstock is removed and passed back into line 33 (Fig. 1) to be dried with the meal.  The oil or miscella which leaves the centrifuge is washed in water-wash mixer 78 and separated from wash water in centrifuge 79, the water passing to decanter tank 81, where solvent may be separated and re-used.  Pump 84 passes miscella successively to preheater 86, evaporator 87, flash chamber 88, and stripper 89, where solvent is removed and condensed by condensers 90, 91.  The oil is finally passed either directly to storage or first to vacuum drier 96 fitted with condenser 97.
