Title: Method of determining distances by means of wireless telegraphy
IPC: G01S17/08
Filed: 1921-01-10
Abstract: 157,372. Burstyn, W. Dec. 15, 1919, [Convention date]. Distances, determining.-In a method of determining comparatively small distances e.g. about 5 km., between two wireless stations one or both of which may be movable e.g. for use of ships, a wave-length greater than the distance to be determined is utilized, measurements based on the intensities of or the phase difference between the electric and magnetic fields being made and the distance calculated from Hertz's complete field equations. The absolute intensity of the received signal from a sender of known intensity may be measured or various comparative measurements mav be made. In one method the maximum received intensities in two main positions are compared by estimate or by currentindicating measuring instruments or are made equal by adding resistance to one, vertical loops rotatable about a vertical axis being used for both sending and receiving aerials, the sender being rotated continuously and the receiver by hand. In another method the phase difference between the electric and magnetic fields is measured. The receiver has two antennae, a vertical aerial and a loop directed on the sender. The received intensities in both aerials are brought into such phase e.g. by a very loose coupling for cne or by the insertion of a resistance in the other antenna, and are so allowed to act on the receiver that they neutralize one another at phase equality of the ether fields. The absolute value of the joint effect may be measured or it may be compared with the effect of a single one of the two antennµ by means of a measuring instrument, by estimate, or by means of a change-over switch which puts adjustable resistance in parallel with the telephone. In a third method, suitable for distances below 1/10th of the wave-length used, the magnetic and electric fields are compared, using the two receiving antennµ as above. In a further method, the sender emits two very different wavelengths simultaneously or alternately by means of the same or two different aerials. One wave is very long as above, and the second very short compared with the distance to be measured. The ratio of the received intensities of both waves is determined by the receiver.

Abstract: 1376993 Detecting hard particles in softer substances H J HEINZ CO 12 Jan 1972 [13 Jan 1971 29 Jan 1971] 1546/72 Heading G1S Hard particles such as bones in softer products such as chicken pieces are detected by needle probes 30, Fig.3, slidable in guide plates 27, 28, 29 attached to an electrical insulation material housing 24 supporting an electrical conducting plate 42. The space between 42 and a gasket 44 defines a chamber which is filled with filtered air under pressure. The whole probe mounting unit 20 may be moved vertically by a double acting hydraulic cylinder 50, Fig.1 (not shown) so that the probes acted upon by the air pressure in the chamber may overcome the resistance of the product 60 against penetration when the unit 20 is lowered. The presence of bone fragments causes contact of some probes with the conducting plate 42 which is itself upwardly movable, and a signal is then given which indicates that a particular product piece must be manually examined at a later working station. The unit 20 is then withdrawn through a stripper plate 57. The probe may be spring-pressed instead of movable against air pressure. In Fig.6 the probes are radially movable in a rotatable drum and are alternately actuated by air pressure from a zone 120 or withdrawn by vacuum from a zone 118. In Fig.7 (not shown) the probes are mounted in a block having an upper chamber alternately connected to pressure and vacuum, and in Figs.8 and 9 (not shown) the device of Fig.7 is combined with a continuously or intermittently movable product conveyer. In Fig.9 (not shown) the probes are operated synchronously with the presence of a product beneath on a moving conveyer.

Abstract: 567,938. Distilling sulphur dioxide. ANGLO-IRANIAN OIL CO., Ltd., ADEY, L. K. S. W., and DOCKSEY, P. Feb. 5, 1941, No. 1558. [Class 32] In the extraction of hydrocarbon oils with sulphur dioxide, the latter is recovered from the extract or raffinate phases by fractionating the extract or raffinate under increased pressure sufficient to enable the sulphur dioxide to be condensed to the liquid phase from the vapours formed without cooling below normal room temperatures. Pressure of one to 'six and a half atmospheres are specified and undue increase in the distillation temperature required by the increased pressure is avoided by mixing the extract with a paraffin hydrocarbon fraction containing 5 or less carbon atoms. A naphtha fraction of boiling range 70-170‹ C. containing 15 per cent aromatics was solvent treated with sulphur dioxide. The raffinate containing 15 per cent SO2 was distilled in a column with a reflux ratio of 1/1, at a pressure of 100 lb., and with base and top column temperatures of 190 and 43‹ C. The overhead was condensed at column pressure using water at room temperature as cooling agent and a condensate containing 97 per cent SO, was obtained. The extract phase containing 85 per cent SO2 was first evaporated in three stages at pressures of 195, 145, and 110 1b. per sq. inch and the extract from the third stage distilled in a column at 190 lb. per sq. inch pressure in presence of 20 per cent pentane, an overhead containing 93 per cent SO2 being obtained.

Abstract: 1,062,997. Semi-conductor devices. ATOMIC ENERGY OF CANADA Ltd. Jan. 14, 1965 [April 30, 1964], No. 1734/65. Heading H1K. A P-I-N diode of the kind (particularly applicable to photo-electric or gamma ray spectrometry) in which lithium from a lithiumdoped N region of a semi-conductor body has been " drifted " across a PN junction to form an I region between the P and N regions is made, with germanium as the semi-conductor material, by a process in which the " drifting " step is performed at a temperature between 50 and 70‹ C., maintained by a boiling liquid in which the body is immersed. The complete process comprises applying a layer of lithium to one surface of a P-type germanium crystal, alloying the lithium to the germanium to form an N-type region therein, applying electrodes, e.g. of nickel, to opposite faces, immersing the crystal in an apparatus (drawing not shown) containing boiling chloroform and applying a suitable potential difference across the PN junction during the immersion. Typically the potential difference is 200 volts and the treatment time 10 days. Since the rate of transfer of lithium ions across the junction decreases with time, it is advantageous to stop the process temporarily, clean the surface (e.g. by mechanical removal of material) apply fresh lithium and then continue the treatment, this being repeated several times if necessary.
