IPC: A47G27/02
Filed: 1964-02-10
Abstract: 1,011,308. Mats for vehicles. C. H. MASLAND & SONS. Feb. 10, 1964, No. 5493/64. Heading A4S. [Also in Division B5] A carpet for a motor car has heel pads bonded thereto, the pads being formed by placing liquid polyvinyl chloride plastisol 23 in a pad-shaped open tray 20, heating the tray to form a skin 31 of gelled or fused plastisol in contact with the tray, or layer of plastisol remote from the surface of the tray remaining unconverted and penetrating the pile 24 but not the backing 26 of the carpet when the open mouth of the tray is pressed thereagainst, heating the tray to fusion temperature of the plastisol and cooling and stripping-off the tray. The skin 31 prevents "grinning" of the pile through the pad and plastic, paper, metal &c. may be placed in the tray before the plastisol is placed therein. In modifications, the plastisol is placed in the tray in two stages, the first layer being gelled or fused before the second layer, which may be of a different composition, is added, or the pile is dried, compressed and deformed by heat and pressure before application of the plastisol. In manufacture it is usual to bring the inverted carpet down on the mouth of the tray. Fillers such as paper, textile mesh, metal grit or powder may be incorporated in the plastisol which consists of thermoplastic resin particles in phthalate and adipate plasticisers.

Construction.  The laser cell 11, Fig. 1A, is formed of optical quartz to which is welded a filling tube 12.  The cell end faces are provided with a partially-reflecting external coating 13 of silver and aluminium which is protected by a thin quartz layer 14. Alternatively, the coating 13 and quartz layer 14 may be internal, Fig. 1B.  The cell is filled with the liquid laser material at room temperature to a level about half way up the tube 12 which is then sealed. The cell is then cooled to a temperature in the range 77 DEG  to 90 DEG  K, for example, by immersion in liquid nitrogen 17, Fig. 2, contained in a quartz Dewar vessel 16.  Laser pumping is effected by a krypton discharge tube 18 provided with a partial reflecting coating 19, the tube being energized from a pulse power pack 21.  The wavelength of the pumping light is <PICT:0983874/C4-C5/1> selected by means of a monochromator and/or filter 28.  Stimulated emission is enhanced in the direction A by the semi-reflecting surface 13 and is observed externally by a photomultiplier 22. Phosphorescent radiation is observed by a photomultiplier 23 positioned at right angles to the optical axis A. Recording of both emissions is effected in an oscilloscope 25 which is fed from the photomultipliers through respective amplifiers 26, 27.  Laser materials.  The glass formed by supercooling may consist of a 10-3 molar concentration of benzophenone (AR grade) in a mixture of methyl cyclohexane and isopentane within the range 3 : 1 and 1 : 2.  The solvents are purified by passage through a silica gel column. Alternatively, the liquid constituents of the glass may consist of acetophenone, benzaldehyde (AR grade), pyrazine or alphabromonaphthalene or a mixture of naphthalene (micro analytical grade) and benzophenone in a mixture of methyl cyclohexane and isopentane. Amongst other examples of suitable materials given are sulphuric acid or phosphoric acid as an inorganic glass and organic complexes such as phthalo-cyanines, chlorophylls, carotenoids, rare earth chelates, and alkali metal and transition metal complexes. Examples of substances suitable for the formation of an organic glass are mixtures of diethyl ether, isopentane and ethyl alcohol, propyl ether and isopentane, and bi-acetyl pyrazine, bromonaphthalene, benzoin, sodium anthracene and sodium benzophenone.

[Class 91] A Diesel fuel is prepared by separating a petroleum gas oil into a light fraction, an intermediate fraction and a heavy fraction, subjecting the light fraction to selective solvent extraction to free it from aromatic hydrocarbons, hydrogenating the heavy fraction and then recombining the three fractions. The selective solvent used in extracting the light fraction may be liquid sulphur dioxide, furfural or a glycol ether, while the hydrogenation of the heavy fraction may be carried out in the presence of a hydrogenation catalyst comprising an oxide or sulphide of a Group 6 metal such as chromium, molybdenum or tungsten, alone or mixed with oxides or sulphides of other metals, such as nickel sulphide, zinc oxide, magnesium oxide or aluminium oxide. The gas oil treated may be a straight petroleum distillate or a product of a cracking or hydrogenation process, or mixtures of these. Apparatus is described in which a petroleum gas oil is subjected to fractionation to give a light fraction boiling below 550‹F., an intermediate fraction boiling between 550‹F. and 650‹F., and a heavy fraction boiling above 600‹F., the light fraction is subjected to solvent extraction in a countercurrent extractor tower, the heavy fraction is hydrogenated in the presence of a catalyst at elevated temperature and pressure, and the three fractions are then recombined. Various addition agents such as ignition promoters, cold starting agents, pour point depressants, viscosity modifiers, dyes, corrosion inhibitors and anti-oxidants may be incorporated in the Diesel fuel. For comparison purposes, details are given of the effect of solvent extraction and hydrogenation on the properties of all fractions of a typical straight run naphthene base petroleum gas oil.
