Title: Apparatus for removing dust from gases
IPC: B01D46/32
Filed: 1945-04-16
Abstract: 593,156. Rotary dust filters. SOC. CIVILE D'ETUDES THERMO-MECANIQUES. April 16. 1945, No. 9499. Convention date, Feb. 16, 1943. [Class 8 (ii)] A dust separator for gas under pressure com-. prises a separating chamber within which rotates a member constructed to provide a plurality of circumferentially arranged cells to which is delivered particulate material, and means whereby dust-laden gas is made to traverse some of the rotating cells and is thereby cleaned, whilst contaminated material is removed from the remaining blocked cells to a screening device. In operation dust-laden gas enters a separating chamber 2, Fig. 1, and traverses rotatable sand-filled cells formed by cone frustrums 3', 3" and radial separators 4, Fig. 2, and is discharged through an opening a, b, c, d in a fixed plate 7 to an outlet 5. Contaminated sand is discharged through an outlet 8 to a rotary screen 11, and the cleaned sand is delivered to the separator at 10 by a screw conveyor 14. In a modification contaminated sand is discharged through traps beneath each cell and which traps are opened only when the associated cells are out of register with the opening a, b, c, d. The sand passes a vibrating screen before delivery to the separator. In a further modification the vibrating screen is helical and so serves to convey cleaned dust to the separator. The Specification as open to inspection under Sect. 91 comprises also a further modification in which the dust-laden air inlet is at the side of the chamber and the sand is held between parallel perforated checks arranged singly or in pairs in each cell. This subject-matter does not appear in the Specification as accepted.

Title: A process for the manufacture of hydrocarbon oils
IPC: C10G21/00
Filed: 1939-03-27
Abstract: 526,863. Purifying oils ; lubricating and turbine oils. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). March 27, 1939, No. 9559. [Class 91] Stable lubricating and turbine oils are obtained by (1) treating a suitable mineral oil distillate with a solvent for naphthenes ; (2) simultaneously (or before or after) treating to remove asphaltenes and resins e.g. by distillation, or precipitation by propane, or by methane under pressure as in Pilat's process, and preferably to remove wax; (3) treating the raffinate with concentrated sulphuric acid, removing the sludge, and blowing with air or other gas below 200‹F. to drive off sulphur dioxide ; (4) further blowing, preferably with air or oxygen, at 220-300‹F. to polymerize unstable components ; and (5) contacting with active bleaching clay e.g. Fuller's earth, Florida clay, or Attapulgas clay. An antioxidant e.g. phenyl alphanaphthylamine or aromatic sulphur compounds may be added to the treated oil. In an example, topped crude mineral oil, propane, and solvent enter an extractor 1 through pipes 2, 3, 4 respectively, extract being withdrawn by a pipe 5, and raffinate flowing through a pipe 6 and a heater 7 to a column 8 in which the propane is flashed off. The raffinate passes through a heater 9 to a fractionating column 11 from which a lubricating distillate is taken through a pipe 12 and a condenser 14 to a tank 15 ; the residue is withdrawn through a pipe 13. The distillate is forced by a pump 16 through a pipe 17 to a vessel 18 in which it is agitated at 50-140‹F. with acid of 93-100 per cent. strength introduced by a pipe 22, agitation being effected by air from a pipe 21 ; after sludge has been withdrawn through a pipe 20, #-2 per cent. of water is added through a pipe 23 to hydrolyse and precipitate dissolved sludge along with "pepper" sludge which are removed through pipe 20. The oil is now heated to 150-190‹F. by a coil 19, and blown until dissolved sulphur dioxide has been removed ; it is then raised to 250- 270‹F, and blown with air for 8-20 hours, cooled to below 100‹F. and passed by a pipe 24 and a pump 25 to a percolator 26 packed with Fuller's earth, and by a pipe 27 to a storage tank 28. Instead of removing dissolved sludge by hydrolysis as described, it may be extracted by acetone or methyl or ethyl alcohol ; or the oil may be heated to above 212‹F. and under pressure with a little water, preferably containing caustic soda, ammonia, or lime. Suitable gases for the first blowing are air, nitrogen, hydrogen, flue gas, and carbon dioxide. The asphalt and resins may be removed by the Duosol process described in Specification 355,294. Solvents specified are liquid sulphur dioxide, furfural, phenol, cresylic acid, and dichlorethyl ether.

Title: Decoding device for a record carrier provided with a multi-track data pattern which includes error protection data and player comprising such a decoding device
Inventor: POLLEN RUDY WILLEM JOZEF
IPC: G11B20/18
Filed: 1995-09-28
Abstract: In a multi-track record carrier the data is stored in words which comprise an increased number of symbols as a result of added redundancy. In order to neutralize so-called burst errors, the symbols of a word are stored in a distributed manner, for example by interleaving. In the case of loss of track, a regrouped word may then actually consist of parts of two or more different words (i.e. words situated on several tracks). Decoding of such a word is prevented in practice in that a series of symbols are invalidated in the case of loss of track, for example by inversion or by means of an invalidity flag.

Abstract: PURPOSE: To freely re-align a semi-trailer and a traction vehicle by providing an electro-pneumatically actuated device for inhibiting the movement every time the brake of a vehicle is operated to control the relative angle between the traction vehicle and the semi-trailer. CONSTITUTION: When brake is applied, the relative angular movement between a semi-trailer 1 and a traction vehicle is produced, and the angular movement is limited by a lock 8 inserted in a center angle A of a fifth wheel 3. The movement limitation is produced by locking the lock 8 in a contact point with the fifth wheel 3. When the operation of the brake device is released, compressed air is discharged from a solenoid valve, and the lock 8 is returned to a non-operating position by a spring 12. The structure of the lock 8 is such that when brake is applied under the condition where the relative angle between the semi-trailer 1 and the traction vehicle is larger than a blocking angle, the operation of the lock 8 is inhibited by the fifth wheel 3.
