Title: Method of reducing variation in anti-knock characteristics of fractions of full boiling range naphtha
Filed: 1960-01-28
Abstract: In reforming a full boiling range naphtha the feed is distilled into a light and a heavy fraction, the former is contacted with at least 30% of the catalyst, mixed with the heavier fraction and contacted with the remaining catalyst, the overall conditions including a hydrogen (recycle gas) to naphtha mol ratio of 4-20, a space velocity of 0.5-3 vol./vol./hr. and a pressure of 150-1,000 p.s.i.g.  The catalyst is preferably platinum-alumina-halogen or may be molybdena- or chromia-alumina. Usually three reforming reactors containing equal amounts of catalyst are employed and the light naphtha, having an end point of 220 DEG F.-270 DEG F., is introduced into the first.  The heavy naphtha, at least 90% of which boils above the end point of the light naphtha, e.g. having an initial boiling point of 240 DEG F.-270 DEG F., is introduced wholly or in part before the second or the third reactor.  Where the feed (C5-400 DEG F.) contains less than 30% naphthenes, the whole of the heavier fraction is passed to the third reactor; if 30%-50% naphthenes are present, 40%-50% of the heavy fraction is passed to the second and the balance to the third reactor; and if more than 50% naphthenes are present, 60%-70% is passed to the second and the balance to the third reactor.  The temperature of reforming the mixture of partially treated light naphtha and heavy naphtha may be higher than that for the light naphtha alone, and may be 850 DEG F.-930 DEG F. for naphthas containing about 20% naphthenes and 900 DEG F.-965 DEG F. for those containing more than 50%.  The feed should be hydrofined if necessary.  The catalyst, may be in fixed or fluidised beds and disposed equally in the reactors or be present in greater amounts in the later reactors as disclosed in Specification 830,439 and U.S.A. Specification 2,654,694.

Filed: 1922-02-03
Abstract: 175,614. ChÛneau, L. J. J. B. Feb. 18, 1921, [Convention date]. Rope railways.-In an aerial ropeway with continuous cable, the tension is regulated by displacing the .supports in any required direction. Each support comprises a rigid upright a which carries the cable and a rigid inclined stay d, the length of either or both of these elements being variable by varying the position of the point of connection. The stay d may have a cap f<1>, Fig. 1, having a pivoted nut f engaged by a threaded spindle e carried by lugs a' secured to the upright a. The Specification as open to inspection under Sect. 91 (3) (a) states also that the length of the stay, which may be a guy rope, may be varied by a tensioning device. The stays are connected to the supports in the neighbourhood of the cable brackets, some of which consist of three parts g, g<1>, g<2>, Fig. 5, (Cancelled) connected by pins h, i, the part g<2> carrying on a pivot j the cable c by means of grips b secured by screws k. The weight of the tractor, when between two consecutive hinged brackets, causes these brackets to incline towards each other, so relieving the tension at that point. This subjectmatter does not appear in the Specification as accepted.

Abstract: 996,794. Analysis synthesis telephone systems; pulse code modulation systems. MINISTER OF AVIATION. Jan. 24, 1964 [Jan. 29, 1963], No. 3570/63. Headings H4L and H4R. In a parametric speech bandwidth compression system a parameter signal derived from the speech signal has its mean level modified so that the signal always lies within a predetermined range of values. Fig. 1 shows an embodiment in which a parameter signal, e.g. a pitch signal, from a speech analyser is applied via a unit 3 to a p.c.m. coder 5 to derive a signal for transmission over a link 7. If the parameter signal is such that the p.c.m. coder is driven to its extreme digital limit, such that it produces an output signal 00 . . . 0 or 11 . . . 1, the indication of overrun unit 9 emits a primary or secondary signal, dependent on the direction of overrun, and the zone storing unit 11 is thereby controlled to feed a positive or negative signal into the difference unit 3 so that the parameter signal fed to the p.c.m. coder is modified and brought back into the coding range of the coder 5. The voltage emitted by the unit 11 is a slowly decaying one so that there can be no permanent build up of modifying signal. Fig. 2 shows the receiver in which the received p.c.m. signal is decoded in unit 13 but any occurrence of the extreme digital signals is recognized as an indication of overrun and results in a voltage being added to the decoded parameter, corresponding to the voltage subtracted in similar circumstances at the transmitter, so that a replica of the original parameter signal is obtained at the output 21. The indication of overrun unit may be arranged to operate on the uncoded parameter signal. Specification 917,987 is referred to.

A tunnel furnace for firing loose material comprises a refractory tunnel with a roof formed with exhaust ports 24, 26 and 28 opening into an exhaust hood 30, a hearth of zirconia tiles 54 disposed on pillars 56 and sloping downwardly from each end of the furnace towards the middle, a flexible platinum tube 52 on the hearth, and gas burners in the side walls below the level of the hearth 54. The tunnel 52 has a bottom lining 58 of refractory material, e.g. zirconia, alumina or barium titanate supporting the top run of an endless belt 62 of platinum looped over rollers 64, 66. A transverse partition 46 divides the refractory tunnel forming a short preheating section 48 which has no burners, and the tunnel 52 extends from this partition through the end wall 38. Charge material is fed on to the belt 62 by a hopper 74 in front of an opening 42 in the end walls 36. The furnace is applied particularly to the firing of lead zirconate titanate ceramics, in which loss of the volatile lead compounds is compensated for by adding excess lead oxide to the mixture. Alternatively, the tunnel 52 may be coated with lead oxide or lead zirconate either directly or indirectly by passing it through on the belt 62.

The cable 16 passes over a pulley 19 carried by cross-bars 20, 21 connecting the runway sections 3b, which are thus lifted when the winch is operated and may be supported by turning down the props 10. When the gun is held by the cable 16 against stops 22, the props 10 may be turned up and held by clips on the runways and the sections 3b lowered by the winch into their lower position, in which the gun wheels may be clamped by an arm 24 on a rod 25 operated by a hand lever 27.
