Title: Process for the preparation of liquid hydrocarbon mixtures with improved octane number and improved volatility for use in motor gasolines
IPC: C10G59/04
Filed: 1957-07-22
Abstract: A gasoline component is produced by catalytically reforming a straight-run gasoline or fraction thereof over a platinum catalyst, distilling the reformate to obtain one or more fractions boiling at least partially above 160 DEG  C. and subjecting at least one of such fractions to thermal reforming (see Group IV (b)). The thermal reformate may be blended with the untreated light platinum reformate in the production or other ratio, preferably components boiling above 200-230 DEG  C. being excluded.  Other gasolines may be blended such as straight-run gasoline, cracked gasoline, particularly catalytically cracked gasoline fractions boiling below 85-135 DEG C., reformed gasoline, polymer or alkylate gasoline, isomerized light hydrocarbon fractions, isopentane, butane or butene, the C4 hydrocarbons being necessary to increase the vapour pressure. Tetra-ethyl lead, and other gasoline additives may be added. Specification 742,769, [Group IV (b), is referred to.ALSO:A straight run gasoline or fraction thereof is catalytically reformed over a platinum catalyst, the resulting reformate is distilled to separate one or more fractions boiling at least partially above 160 DEG  C. and at least one of these fractions is subjected to thermal reforming.  The catalytic reforming may be performed at 480-570 DEG C. under a hydrogen partial pressure of 6-50 atm. gauge.  The reformate subjected to thermal reforming preferably contains no components boiling below 75 DEG  C. and components boiling above 200-230 DEG  C. may also be removed; suitable fractions are all components boiling above 85 DEG  C., or above 105 DEG  C., or above 132 DEG  C. or above 160 DEG  C.  The thermal reforming may be performed at 500-600 DEG  C. and 15-135 atm. gauge, if desired in the presence of hydrogen and/or other gas or vapours such as steam, butane, butene or propane.  Products boiling above 200-230 DEG  C. may be removed.

IPC: C08L61/10
Filed: 1934-08-17
Abstract: Moulded articles are produced by the use of resitol or a mixture containing it as initial material and working according to the process of the parent Specification.  A resitol free from water and other volatile compounds as set out in Specification 350,427 may be used to give clear transparent or patterned articles.  Fillers and colouring matter may be used.  Instead of resitol there may be employed an intimate mixture of finely powdered resol and resite, or resite, novolac and a substance containing a reactive methylene group or a mixture of resitol with either resol, or resite, or novolac together with hexamethylene-tetramine.  In an example, 60 parts by weight of resite are mixed with 40 parts of resol, are melted together at 90--100 DEG  C., cooled and die cast.  In general, the die casting pressure used is the same or a little higher than that used with resol.  The working temperature may be 130--180 DEG  C. or higher.

Abstract: 1328198 Selective reduction of Ni and Fe bearing ores SHERRITT GORDON MINES Ltd 19 April 1971 [10 Feb 1970] 23926/71 Heading C7D Finely divided particles of oxidic nickel and iron bearing ore are treated in suspension in a gas stream containing sufficient gaseous reductant to reduce the nickel oxides (and cobalt oxides if present) in the suspended ore particles to a form soluble in a leach solution, and also to reduce the iron oxide constituent therein to magnetite, whilst passing the suspension through a reaction zone at 370-925‹C for # 15 secs; reducing agent/ore ratio and temperature being controlled such that the process is accompanied by a minimum reduction of iron values to metallic iron. The carrier gas may contain H 2  or CO as reducing agent, and may be produced by reforming naphtha or by partial combustion of heavy fuel oil. As shown carrier gas is supplied via conduit 20 to the reactor 10, e.g. formed by a stainless steel pipe, particulate ore being provided thereto by hopper 25 and conveyer 24, the suspension passing upwards through reaction zone 12 heated by combustion chamber 14 and hence via outlet 30 to scrubber 32 (or alternatively to a cyclone or electrostatic precipitator) where the ore is separated from the gas stream. Unreacted reducing agent may be recycled, other hot gases being otherwise utilized.

Abstract: 391,359. Laying pipes. JOHNSTON, J. T. M., London House, Crutched Friars, London. Aug. 26, 1932, No. 23952. [Class 99 (ii).] In laying pipe sections, a section 28 is lifted from the ground beside a trench 124 by apparatus comprising a U-shaped member 26 at the end of a block and tackle 25 which hangs from a carriage 15 adapted to be traversed along a beam 10, mounted on supports 11, to bring the section over the trench. The section is lowered to the level of the previously laid section 29 and a movement of the supports 11, which are provided with wheels 13, perpendicular to the beam 10, places the section 28 in register with the pipe sections already laid. Instead of moving the supports 11, the carriage may be formed in two parts, the one slidable in the other. A crank 19, operating through chain and sprocket gearing 18, rotates a screw 16 on the beam 10 to traverse the carriage 15. The screw 16 may be formed of sections and be operable from either end and one support 11 may be adjustably connected to the beam 10 by a bracket 20 and removable pin 21. More than two wheels 13 may be provided in which case jacks 14 will not be required to steady the supports. When jacks are provided the apparatus may be tilted by them to move the pipe section into place.

Patent GB-1477593-A (GB)
Title: Electronic timepiece
IPC: G04G3/02
Filed: 1975-06-04
Abstract: The electronic timepiece comprises an oscillator circuit for generating a high-frequency basic signal, as well as a multistage frequency divider circuit (F1 - Fk+n), at least one of the divider circuit stages serving the purpose of generating a time signal derived from the basic signal. In this case, a phase-shifting circuit (6) is provided which is connected in series with the stages of the divider circuit (F1 - Fk+n) between two stages (F2 - Fj). Furthermore, a phase control selection circuit (7) is provided which is connected to at least one of the divider circuit stages which is connected downstream of the stage (Fj) downstream of the phase-shifting circuit (6) for the purpose of generating a control frequency signal in order to feed a phase control signal to the phase-shifting circuit (6). In this case, the phase-shifting circuit (6) can be operated optionally both as an advancing circuit and as a time-delay circuit in such a way that a frequency signal which is advanced or delayed in phase by at least 180 DEG  appears at the driven divider circuit stage in each period of the phase control signal of the phase control selection circuit (7). This permits regulation of the timepiece within a large range of deviations of the fundamental frequency of the quartz crystal vibrator. <IMAGE>
