Title: Improvements in or relating to handling rod-like articles
IPC: A24D3/02
Filed: 1967-07-12
Abstract: 1,235,842. Tobacco-smoke filter making machines. MOLINS MACHINE CO. Ltd. and N. W. JACKSON. 11 July, 1968 [12 July, 1967], No. 32075/67. Heading A2C. In an apparatus for increasing the spacing between a succession of filter plugs P fed endwise in endwise abutment along a common path, alternate ones of the plugs P are conveyed along a first path and the other ones of the plugs P are conveyed along a second path which diverges from the first path so that said other ones become laterally displaced from said alternate ones and, when so displaced, the speed of travel of the plugs P is increased to effect endwise spacing and then the two paths are reunited at a transfer position 7 from which the plugs P are conveyed in a single path in endwise spaced relationship. The apparatus comprises two conveyer devices 6, 8 each including a lower horizontal conveyer disc 21, 42 and an upper conveyer disc 31, 45 respectively. The upper discs 31, 45 are slightly inclined to the horizontal and are driven at different speeds but at the same speeds as their respective lower discs by means of stub shafts 34, 48 and rollers 35, 49 engaging the surfaces of parts 36, 50 in holes formed in the lower discs 21, 42 respectively. The lower disc 21 carries elements 25 regularly spaced around its periphery, and the upper disc 31 similarly carries downwardly depending elements 37 interposed between and in close proximity to the elements 25. At a receiving position 5, alternate plugs P are fed into flutes 26, 38 of the alternating elements 25, 37 at which point the flutes are horizontally aligned. On rotation of the discs 21, 31 through 180 degrees, the plugs P are carried to a transfer position 7 where, due to the inclination of the disc 31, the flutes 26, 38 are displaced in the horizontal plane as shown. The plugs P are then transferred to similar flutes 52, 56 provided in elements 51, 55 on the discs 42, 45 which are rotated at a higher peripheral speed than the discs 21, 31 to effect endwise spacing of the plugs P which are finally delivered at a position 10 in a single spaced line. The plugs P are held in the flutes 26, 38 &c., as required, by guide surfaces (not shown). The use of the apparatus for forming a composite filter rod comprising alternating filter plugs P, P 1  of two different kinds, is also disclosed, a second spacing device being used for the second kind of plug P 1 , the spacing between the spaced plugs being increased by acceleration by further conveyer discs before the two kinds are interposed to form a single composite line on a disc (18).

Title: Improvements in and relating to the actuation of brake bands, reaction bands for epicyclic gearing, or any lever actuation of parts
IPC: F16D65/14
Filed: 1928-11-03
Abstract: 328,660. Wilson, W. G. Nov. 3, 1928. Actuated by springs.-An actuating system for brakes and other devices comprises a lever p, a link l and springs a, the line of thrust of which acts through the connections k between the springs and the link whereby the connection is brought nearer to or farther away from the fulcrum p<1> of the lever according to whether the load on the springs is increased or decreased, so that the leverage moment is varied in inverse ratio to the stress on the springs. As applied to the manipulation of the various reaction bands in a mechanically operated gear box, a bar having levers p, q, lies on a knife edge p<1> at the bottom of the gear box and selectively operates the bands such as 13, Fig. 9, by a strut 11 and toggle mechanism 12. The lever p supports a link l by a knife-edge n and a socket k is supported in the other end of this link by a knife-edge m. A stop s on the lever p limits the inward movement of the link l and a stop r on the link l limits the outward movement of the socket k. A spring a, for applying the bands, is engaged between plates band c provided with extensions d, e which telescope into one another, and the plate c engages a ball f fixed to the casing g whilst the plate b is extended at h to engage in the socket k. The foot pedal engages the arm q through a strut 2, Fig. 9, and when the pedal is depressed so that the lever q, is down, the gears are free and the spring a is fully compressed, whereby the resistance to movement is least due to the proximity of the line of thrust of the spring to the knife edge p<1> When the foot-pedal is raised the lever p, q, turns on the knife-edge p<1> with the link l in contact with the stop s and a slight increase in resistance occurs up to the position in which the pivots f, n and k<1> are in alignment. When this position has been passed the link l swings rapidly away from the lever p and contacts through the socket k with the stop r, Fig. 2. The resistance to movement thus rapidly increases until a maximum is reached which corresponds to the engaged position of the brake band. Only one socket member may be used and the stops may be placed in various positions.

Abstract: 822,628. Electroplating with copper. METALLIC INDUSTRY N.V. Oct. 22, 1956, No. 32166/56. Class 41. Copper is electrodeposited from an aqueous copper salt solution containing at least one mol. per litre of a diamine having a boiling-point between 100‹ and 150‹ C. Examples of suitable amines are ethylene diamine, its N: Nldimethyl and -diethyl derivatives, and propylene diamine. To reduce the disadvantage of the volatility of the amine, which should be present in excess, there may be added to the bath monoamino carboxylic acids having a higher dissociation constant, e.g. glycine, α- or #-alanine, glutamic acid, or γ-aminobutyric acid. An anionic wetting-agent, e.g. sodium lauryl sulphate, may also be used. Specific examples are given employing copper sulphate, a diamine, and an amino acid together with a wetting agent to give baths of pH about 8.5 from which at 58‹ C. there was obtained a bright deposit of copper which could be nickel-plated without polishing.

Patent GB-500502-A (GB)
Title: Improvements in cathode-ray tube scanning systems
IPC: H01J29/74
Filed: 1937-11-29
Abstract: 500,502. Cathode-ray tabes. HAZELTINE CORPORATION. Nov. 29, 1937, No. 32900. Convention date, Dec. 24, 1936. [Class 39 (i)] In a cathode-ray tube for television receiving or transmitting systems the aspect ratio of the scanned pattern on a target is varied from what would be obtained by the usual scanning means without otherwise altering the configuration of the scanned pattern ; a refracting field is used which serves to increase the size in one or both directions of the picture obtained so that smaller deflecting currents or voltages are necessary. The beam is deflected by magnetic or electrostatic means to scan a rectangular area at the end of the tube, which may be provided with a fluorescent screen or a photoelectric mosaic. The refracting field comprises magnetic or electrostatic means and in the former case is produced by two permanent magnets 24, 25 arranged at opposite sides of the tube and between the normal deflecting means 20, 21 and the target; the magnets give rise to a field which is zero in a vertical plane through the 'tube axis but increases uniformly on each side of this plane, and is of opposite polarity on each side. The cathode-ray beam is refracted by the field due to these magnets in such a direction as to increase the width of the area scanned, such increase being directly proportional to the deflection. The height of the area scanned may be similarly increased.

Apparatus for measuring the concentration of salt in a liquid comprises an A. C. bridge circuit 4 having first and second branches 4a, 4b each comprising a diode and a resistor in series, a third branch 4c comprising a resistor and a fourth branch 4d comprising a conductivity cell, wherein the equilibrium of the bridge is effected by adjusting one of the resistors and the out of balance voltage is taken from the connections between respectively 4a, 4b and 4c, 4d and is fed to a transistorized D. C. amplifier having an indicator light in its output circuit. As shown, the out of balance voltage is taken from a potentiometer 7 forming part of each of the first and second branches 4a, 4b and is amplified by a transistor 12 before passing to transistor 17 which conducts when the bridge is out of balance. At the balance point, transistor 17 becomes non-conducting and transistor 18 conducts thereby lighting the indicator light 20. The sensitivity of the apparatus is determined by the value of resistor 21. In operation, the potentiometer 7 is adjusted manually, starting from one end and the salt concentration is deduced from the setting of the potentiometer at balance. Resistor 15 has a negative temperature coefficient to compensate for changes in ambient temperature.

Filed: 1929-11-05
Abstract: 337,971. Etablissements Industriels de E. C. Grammont et de A. Grammont. Dec. 10, 1928, [Convention date]. Vacuum tubes.-Electron-emitting filaments are coated with alkaline-earth oxide by depositing on the filament a single or double cyanide of the alkaline-earth metal and by decomposing the cyanide to form the oxide after the filament is mounted in the electron-discharge device. Cyanide crystals may be crushed in an atmosphere free of carbon dioxide and suspended in a liquid such as acetone or alcohol to coat the filament by immersion or atomizing &c. Alternatively, the cyanide may be formed by coating the filament with a mixture of alkaline-earth carbonate and pure carbon and heating in a current of nitrogen. The filament, may be of pure or oxidized tungsten, or of tungsten coated with oxidized metal such as iron, nickel or copper, or may be of the type used in gas-filled valves, i.e. may be spirally wound with fine taping to retain the suspension by capillarity. The cyanide is converted to oxide by heating in oxygen or air at reduced pressure, or in vacuo if the filament is oxidized, or in steam, in which case ammonia is formed.
