Title: Process of insulating electrical apparatus
IPC: H01B3/22
Filed: 1930-12-24
Abstract: Oils for electrical insulation or for motor spirit are desulphurized by treatment with metals such as mercury, lead, copper, amalgams of lead, copper and brass or their oxides or other compounds.  The oil may be forced through a layer of amalgam of metal turnings by inert gas pressure, or may be filtered through asbestos, fuller's earth or silica gel containing metals, amalgams, or metal oxides or compounds in fine division.  The vapours of metals, more especially mercury vapours, may be passed through the oil to be purified during cooling, or the oil is distilled over metal amalgam or compounds.  The purification is carried out at a low temperature, preferably below 80 DEG  C. and out of contact with oxygen, e.g. in an atmosphere of inert gas such as nitrogen or carbon dioxide.  Reducing agents such as pyrogallol or hydroquinone may be added to the materials before or during treatment.

Abstract: 1,139,801. Treating tobacco. GALLAHER Ltd. 24 June, 1966 [25 March, 1965], No. 39228/64. Heading A2C. A method of producing a powdered tobacco extract comprises extracting the soluble constituents from tobacco with a solvent, e.g. water, atomizing the solution and evaporating the minute droplets quickly with a hot gas to form a powder of the solute. The evaporation is carried out in a spray-dryer using hot air. The tobacco powder may be stored in containers for subsequent use as e.g. a coating to a web of paper or reconstituted tobacco. Preferably the web is formed from the non-soluble residue of the extraction process, this residue being formed into a tobacco web by a conventional paper making machine. The powder is made into a concentrated solution and coated on the web. The coated web may then by spray painted with a dispersion of finely divided tobacco in water. A quantitative process example is described.

Title: Fishing reel with planetary drive
IPC: A01K89/016
Filed: 1972-08-30
Abstract: 1350533 Fishing reels C C VALENTINE 30 Aug 1972 [15 Sept 1971] 40185/72 Heading A1A [Also in Division F2]  The spool 24 of a fishing reel is rotated in a clockwise direction, to wind in a fishing line, by a handle 58 acting through a planetary gearing arrangement 54, 56 which, as the line is pulled off permits the spool to rotate anticlockwise but does not effect a corresponding rotation of the handle 58 about the spool's axis of rotation. The spool 24 is rotatably mounted on a shaft 22 and has a gear 56 connected to it which meshes with a pinion 54. The pinion 54 is fixed at one end of a spindle 50 rotatably mounted in a bearing block 52 connected to a disc 32 which itself is rotatably mounted via a bearing block 34 on the shaft 22. The handle 58 is rigidly connected to the spindle 50 so that for winding in a line the disc 32 is rotated by means of the handle which acts as a reactive member to prevent the pinion from rotating about the spindle's axis and hence as the pinion orbits the gear 56 it will drive the spool. When the line is pulled off, the gear 56 will drive the pinion 54 which then acts as an idler gear and rotates with the spindle 50 without causing the disc 32 and handle 58 to rotate about the shaft 22. The reel has a brake and ratchet assembly 60 comprising an axially slidable brake disc 62 and a toothed ratchet plate 64 whose teeth 66 cooperate with a spring biased plunger 68 on the spool to permit the spool to rotate freely in the clockwise direction whilst providing adjustable resistance to counter clockwise rotation. A nut 76, threaded on the shaft 22 is axially displaced to adjust the brake disc 62 which frictionally engages the ratchet plate 64 to apply a braking action on the spool. The spool 24 and disc 32 are retained on the shaft 22 by a spring biased latch 40 which normally engages a groove 46 on the shaft 22.

Abstract: 1485349 Apparatus for aiming a gun PERKIN-ELMER CORP 6 Oct 1975 [7 Oct 1974] 40828/75 Heading F3C An apparatus for indicating a desired angle of elevation or of azimuth of a gun comprises a spherical lens 10 having a reflecting surface 12 which reflects visible light of a first wavelength and transmits therethrough visible light of a second wavelength, and sources 26 of illumination fixedly mounted with respect to the lens 10 and able to transmit light of the first wavelength to the reflecting surface of the lens, each of the sources 26 being positioned to direct light to a different region on the reflecting surface. The sources 26 are ends of fibre pipes 20 which are coupled to respective diodes of a light emitting diode array within a range finder 28 and the wavelength of the light emitted is 0À65 micrometres. In use the desired angle, of elevation or of azimuth, is obtained by emitting light from the appropriate source 26 to produce a spot of light, 32 say, on the reflecting surface 12. The target is viewed by an operator positioned at 18 and looking through the lens and, when the latter is mounted on the gun, the elevation angle 14 is measured from a horizontal reference line 16 and equals the angle of elevation of the barrel of the gun. The operator moves the gun to cause the lens 10 to rotate about 18 and the spot of light 32 to align with the target, the gun now has the desired elevation and similar apparatus is then used to obtain the desired azimuth of the gun.

Abstract: 1,263,796. Analogue stores. MULLARD Ltd. 18 Aug., 1969, No. 41159/69. Heading G4G. An analogue storage element includes an input coil 4 for coupling signals to be stored to an almost closed magnetic circuit containing remanent magnetic material, the circuit having a gap substantially filled by a flat Hall plate provided with input terminals for a " read signal", and output terminals for the Hall voltage. As shown, the Hall plate 2 is in the form of a thin film deposited on a magnetic substrate 1 and contacted by one leg of member 3, both the substrate and the member 3 being of remanent, preferably "square loop", magnetic material. A standard "read" current, presettable by a potentiometer, may be fed to contacts 2a, 2b, and the output terminals 2c, 2d, 2e connected to the input terminal of a D.C. differential amplifier to provide an amplified Hall voltage proportional to the remanent magnetization which represents the stored signal. For optimum linearity, the stored signal may be set up by a "closed loop", method, in which the input signal is fed to the coil via one input terminal of a differential amplifier, to the other terminal of which the output Hall signal is fed via a negative feedback path (Fig. 3, not shown). Weighting of a plurality of signals by a corresponding plurality of weighting factors may be accomplished by using a number of separate storage elements, the weighting factors being stored in the magnetic members, and the signals to be weighted being applied to the Hall plate input terminals 2a, 2b; the weighted signals may be summed by connecting all the Hall plate outputs in series.
