Title: Processes for refining hydrocarbon oils
IPC: C10G21/12
Filed: 1936-03-23
Abstract: In the selective extraction or dewaxing of hydrocarbon oils, the oils are treated with one or more of the following solvents, acetonylacetone, dipropyl ketone, acetyl acetone, acetophenone, diacetyl, benzal acetone, fluorenone, benzene sulphonic acid, benzoic anhydride, ethylene oxide, allyl alcohol, phenyl propyl alcohol, resorcinol mono- or di-methyl ether, thioacetic acid, propylene oxide or methyl propyl ketones.  These solvents extract the nonparaffinic constituents from the mineral oils.  Mineral oil distillates, low temperature or brown coal tar oils may be treated.  The extraction may be effected in a batch or countercurrent process, and the selective solvents may be mixed with auxiliary solvents such as (a) aromatic, or hydroaromatic hydrocarbons, nonselective halogenated hydrocarbons, or nonselective ketones, esters, ethers e.g. diethyl ether, ethyl acetate or methyl ethyl ketone, (b) alcohols, or organic acids which decrease the selective power of the selective solvent, and (c) low-boiling paraffinic hydrocarbons e.g. propane and butane. The oil raffinate may be further treated with clay at 450 DEG  F. Mineral oils may be dewaxed with a mixture of one of the selective solvents which are poor solvents for wax with auxiliary solvents of classes (a) or (c), and may be effected prior to or after extraction. The wax is separated from the chilled solution by decanting, filtering or centrifuging.  The slack wax containing some oil may be further treated with the solvent mixture to produce petrolatum. Solvents are recovered from the dewaxed oils and the oil extracts by distillation or by extracting the solvent by washing with another solvent.  The resulting mixture of solvents is then distilled or treated with water or other agents providing separation. Specifications 466,977, 466,979, and 466,980 are referred to.

Title: Improvements in and relating to the production of artificial fibres
Inventor: BAMFORD CLEMENT HENRY
IPC: D01F6/60
Filed: 1950-04-11
Abstract: Artificial fibres are formed by extruding into a setting medium a solution of a copolymeric polypeptide of dl-b -phenylalanine and dl-leucine in benzene or an aliphatic halogenated hydrocarbon or mixtures of such solvents.  Suitable halogenated hydrocarbons are chloroform, carbon tetrachloride and methylene chloride.  The solutions may be dry spun into hot air or wet spun into a coagulating liquid which is a nonsolvent for the polypeptide and preferably miscible with the solvent used to dissolve the polypeptide.  Suitable coagulating liquids are petroleum ether, acetone, methyl alcohol, ethyl alcohol and the propyl alcohols.  A polypeptide solution of a concentration of 5-15 per cent is satisfactory, especially a 5 per cent solution in benzene.  When using methylene chloride, however, concentrations of 20-30 per cent are preferable, particularly for dry spinning.  The polypeptides are prepared as described in Specification 675,298, preferably using equi-molecular proportions of anhydrocarboxy-dl-b -phenylalanine and anhydrocarboxy-dl-leucine. Specifications 542,034 and 675,299 also are referred to.

A phonographic device for automatically answering and recording incoming calls comprises a continuous loop of magnetic tape co-operating with at least one stationary sound head and at least one movable sound head. The stationary sound head is used for recording and reproducing a fixed reply message on one track, and the calling subscribers' messages are recorded (and later reproduced) by the movable sound head on another, spiral, track or on a plurality of parallel tracks, the movable sound head being stepped by a pawl-and-ratchet arrangement which includes an indicator so that the sound head may be set by hand to the required track for reproduction. An erase head is associated with each sound head. The device is set in operation by incoming ringing current, either picked up inductively or fed directly to a relay. A solenoid operates a lever to lift the cradle switch, the handset having been removed and placed with its transmitter near a loud-speaker which reproduces the fixed reply message. Incoming speech currents for recording are picked up either inductively or directly. At predetermined intervals the required switching operations and the operation of a solenoid to step the movable sound head are carried out under the control of markings on the tape, which may take the form of holes allowing contact between circuit elements on opposite sides of the tape. A manual selector switch facilitates use of part of the apparatus for loud-speaking telephone conversations. Transistor amplifiers are used.

Title: Method of producing kinematograph films for synchronous working with sound films
IPC: G03B31/00
Filed: 1929-03-21
Abstract: 332,898. Dessau, E. March 21, 1929. Cartoon and like kinematograph films, producing.-A method for preparing a cartoon film, " trick film," or the like for subsequent synchronized working with an existing sound-record film, consists in first examining the sound-film and noting visual indications of particular parts of the record, after which the picture film is prepared by using a kinematograph camera geared to an apparatus through which the sound film is simultaneously fed, this apparatus and the camera being provided with observation devices which enable the objects or drawings photographed to be arranged, changed, or moved appropriately to the indicated parts of the soundrecord. As an example, there is described a method of using the apparatus shown, for making a talking film in which a collar and scissors appear to talk. The apparatus comprises a kinematograph camera arranged above a table 2 on which the objects 3, 4 to be photographed lie. The picture film is fed through the camera by mechanism comprising shafts 9, 10 and a handdriven shaft 11. Geared to the shaft 11 through wheels 13, 14 and a clutch 16 is a shaft 17 for feeding past an observation panel 19 a sound film 18 on which the speech to be reproduced has been previously recorded. Clockwork mechanism 20 is provided for feeding the sound-film, when required, independently of the picture film, past an optical sound-reproducing device diagrammatically shown at 23. Indicating marks or numerals may be made along the edge of the sound-film throughout its length, or a counter driven by the shaft 17 may be arranged at 24. A counter 33 showing the same indications may be driven from the shaft 10. An optical "finder" comprising a screen 25 suitably arranged in conjunction with lenses, mirrors, prisms, &c. 30, 31 and 36, 27, 29 is provided to enable an image of the objects on the table 2 to be seen in juxtaposition with an image of the part of the soundfilm passing the observation panel 19 together with the marking at the edge of the film or the indication of the couter 24. In using the apparatus, the clutch 16 is first disengaged, and the sound-film is driven past the sound-reproducing device 23 at the normal speed, whilst the indications given by the counter 24 at particular parts of the record are read and noted. After this preliminary examination, the sound-film is slowly driven by hand, and more detailed observations are made, using the device 25. Finally, the camera is operated simultaneously with the slow feeding of the sound film past the observation device. By watching the images on the screen 25, the objects 3, 4 can be so arranged, before individual photographs are taken, that their successive positions are appropriate to the matter recorded on the sound-film, as indicated by the number or markings previously noted. The picture film thus obtained and the sound-film may be printed on to a single film, for projection and sound-reproduction in the usual way.
