Title: Process for the manufacture of condensation products from olefines and unsaturated hydrocarbons
IPC: C07C2/66
Filed: 1929-08-06
Abstract: 316,951. I. G. Farbenindustrie Akt.- Ges. Aug. 4, 1928, [Convention date]. Mineral and tar oils.-Olefines containing at least three carbon atoms in the molecule are condensed with each other or with aromatic hydrocarbons in the presence of a hydrosilicate possessing a large surface and high porosity. Suitable hydrosilicates are those of aluminium and magnesium, such as bleaching earth, Florida earth, and Fuller's earth, to which other condensing agents .may be added, such as a metal halide or an addition compound of an olefine with an aluminium halide. Aromatic hydrocarbons mentioned are benzene and its homologues, polynuclear hydrocarbons such as naphthalene and anthracene, and partially-hydrogenated compounds, such as tetrahydro-naphthalene. As olefinic components may be employed the technical products obtained in the refining of oils by the Edeleanu process. The olefines may also be employed diluted with other gases, e.g. in the form of oil gas or cracking gas. The reaction is facilitated by the use of raised temperature and increased pressure, and also by the presence of hydrogen halides. A solvent may be used. According to one of the examples, a mobile Edeleanu extract is treated in the presence of Fuller's earth with propylene at elevated temperature and pressure, and yields, after vacuum distillation, a bright odourless oil; similar results are obtained by using butylene amylene or cyclohexene. Specifications 291,137 and 296,034, [both in Class 2 (iii), Dyes &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the condensation of olefines containing at least three carbon atoms with aromatic and aliphatic compounds containing a double bond; phenols are mentioned as suitable aromatic compounds. This subjectmatter does not appear in the Specification as accepted.

Patent GB-1104353-A (GB)
Title: Covering material for model airplanes and other frames and methods for applying same
IPC: A63H27/18
Filed: 1966-06-02
Abstract: A covering material for a frame, e.g. a model or regular size aircraft frame, comprises a flexible clear heat shrinkable film of polyester resin coated on one side with only a layer, a heat sensitive adhesive, pressure sensitive adhesive, or solvent sensitive adhesive, containing colouring, e.g. a dye pigment. The adhesive may (1) be pressure sensitive consisting of an acrylic resin, e.g. an acrylic polymer or copolymer; (2) include an inoperative, i.e. non-adhesive, portion; or (3) be dry and non-tacky.  Tacky adhesive may have a layer of paper releasably attached thereto or may be rendered dry and nontacky by the application thereto of a particulate material, e.g. zinc stearate.  The frame, e.g. a model or regular size aircraft frame, may be covered by applying a predetermined length of the covering material to a section of the frame so that the film is the outer side and thereafter applying heat to the film to cause the film to shrink tautly to the contours of the frame and the adhesive to bond the film to the frame.  After application of the material to the frame the material is smoothed out so as to press the adhesive layer to the area of the frame.  Heat may be applied to spaced apart areas of the film, e.g. at the perimeters of the frame, to cause a first portion of the adhesive layer to bond a first part of the film with the frame, heat is then applied to a second part of the film between the areas to cause the film to become more pliable and to cause the second portion of the adhesive to bond a second part of the film to the frame, and cooling the second part of the film to cause the film to shrink tautly to the contours of the frame.  The frame may be made from a porous material, e.g. balsa wood, and heat applied to the film causes the face of the adhesive layer adjacent to the porous frame to impregnate the pores and to make a secure bond therewith.

Filed: 1934-08-27
Abstract: 443,435. Sound-directing appliances. COUTTS & CO., 440, Strand, London, and JOHNSON, F., 218, Victoria Drive, Eastbourne, (Representatives of JOHNSON, J. Y.).- (Philadelphia Storage Battery Co. ; Ontario Street, Philadelphia, U.S.A.) Aug. 27, 1934, No. 24642. [Class 13] [See also Group XXXIX] Sound-deflecting plates mounted in front of the aperture in the baffle-board of a loud-speaker with conical diaphragm comprise inner vanes 6, 7, outer vanes 8, 9, and a tranverse vane 10. The smaller dimension of the vanes 6 ... 9 is less than the longest wavelength for which the radial distribution of sound intensity (without the deflectors) is not uniform. The vane 10 may be near the bottom or the top of the device and is inclined to the horizontal so as to deflect the sound towards the listener. Apertures 22 in the vanes 6, 7 prevent the masking of sounds of very high frequency. The device is used with a loud-speaker in which the radial distribution of sound intensity is uniform for low frequencies while the axial frequency-response characteristic increases with increasing frequency, preferably at frequencies over 1000, and the effect is to give uniform radial distribution of sound intensity at high frequencies and uniform axial frequency-response.

Title: Improvements in or relating to the extraction of phenols and pyridine bases from oils containing them
IPC: C07C37/72
Filed: 1959-07-17
Abstract: Phenols and pyridines are extracted from oil with aqueous alkali metal phenolate solution which is then washed with toluene and distilled, the major portion of the phenols being recovered from the bottoms fraction while pyridines are recovered from the overhead fraction by washing with 20% sulphuric acid and the residual vapour is condensed to produce an oil phase, which is added to the oil to be extracted, and an aqueous phase containing additional phenol values, which is recycled to the process prior to the step of washing with toluene.  The distillation may be effected by indirect heating with steam.  In a modification (applicable to distillation using direct heating with steam), the overhead fraction is washed with an aqueous solution of alkali metal phenolate and/or hydroxide before washing with sulphuric acid and the resulting wash liquor, and not the aqueous phase resulting from the sulphuric acid washing, is recycled. The washing treatments may be effected in a single column.  The initial extraction may be effected in a ten-stage countercurrent extractor, sodium phenolate being introduced at the first stage and passed countercurrent to oil introduced at the sixth stage and toluene introduced at the tenth stage.  The temperature may be 80 DEG C. in the first to sixth stages and 60 DEG -80 DEG C. in the sixth to tenth stages.  The bottoms fraction may be oxidized with air, and extracted with isopropyl ether, the extract being washed with 20% sulphuric acid which is then passed to the overhead fraction washing stage.  Examples are given.
