Title: Improvements in or relating to process for stabilizing hydrocarbon oils
IPC: C10L1/10
Filed: 1953-06-19
Abstract: The oxidation of hydrocarbon oils is inhibited by contacting the oil at a temperature below 212 DEG F. with a mixture of different oil-insoluble substances which would form a buffer solution having a pH of 9.5-10.5 in dilute aqueous solution.  The mixtures are (1) a metal salt of a polybasic acid and its corresponding acid salt (2) an amine and its salt or (3) a weak acid and its metal salt.  The metal salt of (1) may be an alkali metal, e.g. sodium, salt of phosphoric, carbonic or boric acid, e.g. Na3 PO4 and Na2 HPO4, K3 PO4 and K2 HPO4, Na2 CO3 and NaHCO3 and K2 CO3 and KHCO3.  Amines referred to are methylamine, butylamine and methyl thionyl n - butylamine; amine salts specified are hydro-chlorides and sulphonates.  Weak acids referred to are boric acid and glycocoll. The mixture of substance may be deposited on a porous carrier which is suspended in the oil, or may be dispersed or suspended in the oil.  In an example, a distillate oil containing free sulphonic acids is treated with a fabric impregnated with aqueous solutions of a mixture of sodium carbonate and sodium borate or of trisodium phosphate, both solutions having a pH of 10.

Patent GB-828710-A (GB)
Title: Improvements in and relating to the production of acrylonitrile
Filed: 1956-06-01
Abstract: Acrylonitrile is produced by passing through a reaction zone containing a heated aqueous cuprous chloride solution, acetylene, and hydrogen cyanide in an amount exceeding the amount required for the conversion of said acetylene to acrylonitrile, reacting said acetylene and hydrogen cyanide in said reaction zone to form acrylonitrile, passing the gases containing said acrylonitrile and acetaldehyde formed as a by-product in said reaction zone into an absorption zone, reacting said acetaldehyde and said excess of hydrogen cyanide in said absorption zone to form lactonitrile, removing said acrylonitrile and lactonitrile together from said absorption zone, recycling the residual gases into said reaction zone, and separating said acrylonitrile and lactonitrile.  The formation of lactonitrile may be effected by means of an alkaline catalyst, e.g. sodium cyanide or sodium hydroxide.  The absorption zone is maintained at a temperature of - 10 DEG  to + 20 DEG  C., advantageously about 0 DEG  C.  The acrylonitrile and lactonitrile are removed from the absorption in the form of an aqueous alkaline emulsion.  Part of the emulsion may be recycled and passed through the absorption zone countercurrently to the gases to absorb the acrylonitrile contained therein.  The emulsion can be stabilized by acidification and separated by distillation into acrylonitrile and lactonitrile.  The latter may be acidulated with acetic acid and subjected to fractional distillation to split it into acetaldehyde and hydrogen cyanide.  The hydrogen cyanide is recycled, with the gases leaving the absorption zone, to the reactor.  The optimum concentration of HCN in the gases leaving the reactor is 10 to 15 g. per cu. m.

Title: Process for increasing the frequency of crimps in difficultly crimpable continuous filaments
IPC: D02G1/12
Filed: 1966-04-20
Abstract: In a process for increasing the frequency of crimps in continuous filaments A which are relatively difficult to crimp, they are blended with at least 10% by weight (based on the total weight of filaments) of easily crimpable continuous filaments B and crimped in a stuffing-box.  Filaments B, under the same operating conditions in a stuffing-box, have a crimp frequency of at least 1.3 times that of filaments A.  The difference in crimpability may be due to differences in the nature and/or state of the filament material resulting, for example, from different response to heat treatment, and/or denier.  Thus, filaments A may have a denier of at least 10 e.g. 30-50 per filament and filaments B a denier of less than 10 e.g. 2-7 per filament.  The filaments may be of the same material e.g. polyethylene terephthalate.

Title: New artificial resinous condensation products and their manufacture
IPC: C08G79/025
Filed: 1940-12-09
Abstract: Resinous condensation products of low flammability are prepared by heating to a temperature above 150 DEG  C. but not exceeding about 250 DEG  C., a liquid mixture of a liquid or fusible phosphonitrilic polymer and a secondary or tertiary aromatic amino derivative wherein the amino group is directly bound to an aromatic nucleus and also to a carbon atom directly linked to a terminal oxygen or imino group. The reaction may be conducted in the presence of solvents.  The condensation products may be obtained in fusible thermoplastic condition, in which state they are soluble in various organic solvents and may be softened with plasticizers, and are compatible with rubber, chlorinated rubber, phenol-formaldehyde and alkyd resins; they are insoluble in benzene and paraffinic hydrocarbons; continued heating converts them to an infusible and insoluble state. Specified secondary and tertiary amine derivatives are acetanilide, propionanilide, benzanilide, p-nitroacetanilide, aceto - a  - naphthylamide, p - hydroxyacetanilide, phenyl urea, diphenyl urea, diphenylguanidine, dimethyl diphenyl urea, diethyl diphenyl urea, p-toluyl urethane, diphenyl urethane, phenyl urethane and sodium acetanilide.  Volatile by-products of the reaction may be removed by distillation under reduced pressure.  In example: (1) phosphonitrilic chloride consisting mainly of trimer and tetramar is fused with acetanilide and the mixture further heated to 200 DEG  C. for two minutes, hydrochloride and acetyl chloride being removed under reduced pressure; the cold condensation product is purified by grinding with benzene yielding a product soluble in alcohol and acetone and suitable for a baking lacquer; (2) a solution of phosphonitrilic chloride and acetanilide in nitrobenzene is refluxed for three hours, the resinous product precipitating out of the solution; (3) and (4) condensation products are obtained in a manner similar to (1) from symmetrical diphenyl urea and symmetrical diphenyl guanidine; (5) a mouldable composition is obtained by compounding with vulcanizing agents &c. a product obtained by refluxing a decahydronaphthalene solution of rubber, phosphonitrilic chloride and diethyl diphenyl urea.

Title: Improvements in or relating to ships' logs
IPC: G01P5/06
Filed: 1936-06-24
Abstract: 475,200. Ships' logs. OTTWAY & CO., Ltd., W., and OTTWAY, W. R. June 24, 1936, No. 17580. [Class 97 7 (ii)] Relates to ships' logs in which a rotor is mounted at the end of a tubular member adapted to project through an aperture in the ship's hull and in which the pressure of the water near the rotor is utilized to force oil to the rotor shaft. The oil reservoir 13 is fast with the tubular member 2 and the water pressure is led thereto and the oil under pressure is led therefrom to the rotor shaft through conduits 6, 15, wholly within the tubular member so that the apparatus may be readily removed, e.g. for repair, as a unit. The water pressure is led from an orifice 7 near the rotor through the conduit 6 to the head of a cylinder in the housing 1. A piston 4 working in the cylinder is hollowed to form a subsidiary cylinder in which works a stationary piston 10 fixed to the housing 1. The subsidiary cylinder and the hollow interior 13 of the piston 10 form the oil reservoir, from which oil under pressure is supplied through passages 14 to the conduit 15.

Title: Improvements in or relating to goniometers
IPC: G01S3/788
Filed: 1954-06-16
Abstract: 771,488. Locating objects by radiation beams. TURCK, J. June 16, 1954 [June 17, 1953], No. 17645/54. Class 40 (3). Apparatus for locating the position of an object with respect to reference axes comprises a screen of radial alternate opaque and transmitting sectors on which an image ot the objective is projected, the image being caused to move in a circular path relative to the screen, a photo-cell receiving the modulated image passing the screen and a frequency discriminator fed by the photo-cell from which is derived the object position. As shown, an image of the field in which the object to be located may appear is imaged by a lens 2 on to the photoemissive screen 3 of an image converter an electronic image being produced on the fluorescent end screen 4. Beyond the end screen is a fixed modulating device 9 consisting of alternately opaque and transmitting positions as shown in Fig. 7. Time bases 7x and 7y generate sinusoidal voltages differing in phase by 90 degrees which are applied to deflecting coils so as to rotate the centre target on the end screen thus, if the target is on the axis of the tube it describes a circle having the axis of the tube for centre, while if it is off the axis it describes a circle such as that shown in Fig. 7. Thus the photo-cell receiving light which has traversed the disc produces an output of constant frequency where the target is on the tube axis and of cyclically varying frequency when the target is off the axis. The cell output feeds an amplifier 10 and a frequency discriminator 11 the output of which varies with varying frequency. The discriminator 11 feeds a pair of phase detectors 12x, 12y respectively fed with the outputs of time bases 7x and 7y and producing at terminals X and Y outputs representing the co-ordinates of the target which may be used to operate servomotors where, for example, the device is a guided missile. The outputs at X and Y may be differentiated at 14x and 14y to yield rate components. Instead of the sections being divided by straight lines they may be wavy or curved. In a modification (Fig. 12, not shown), the optical image is focused on to the modulating disc by way of an inclined rotating mirror which is not mounted at right angles to its axis of rotation. Thus the image of the target is made to describe a circle over the surface of the fixed modulating disc. Operation is otherwise as for the embodiment described, except that the comparison signals for the phase detectors are generated by a disc interrupting light reaching a further photo-electric cell.
