Title: Process for hydrorefining sulphur-containing hydrocarbon distillates
IPC: C08K5/18
Filed: 1962-11-06
Abstract: In a proces for hydrorefining a sulphur-containing hydrocarbon distillate, a charge stream of said distillate is contacted in the presence of added hydrogen at superatmospheric pressure and elevated temperature, preferably 150-260 DEG C., with a hydrorefining catalyst in a first reaction zone, the effluent from the first zone is heated to a higher temperature, preferably 260-427 DEG C., and contacted at superatmospheric pressure with a hydrorefining catalyst in a second zone, the effluent from the second zone is separated into a gaseous hydrogen-containing stream and a liquid stream, at least a portion of the gaseous stream is recycled to the first reaction zone and at least a portion of the liquid stream is recovered as product, the process is characterized in that the said gaseous stream is first subjected to a purification treatment for the removal of hydrogen sulphide, preferably to below 0.35 grains/SCM, on the thus purified stream is introduced into the first reaction zone simultaneously with the distillate charge stream.  Such an amount of liquid from the second zone effluent may be recycled to the first reaction zone such that the combined feed ratio is maintained within the range 1.2:1 to 6:1. The removal of hydrogen sulphide from the recycle gas may be effected by means of stripping media, liquid and/or solid adsorbents, or a caustic wash.  Suitable catalysts for the present process comprise at least one component selected from Cr, Mb, W, Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, and Pt, especially catalysts comprising Mb and a member of the iron group, e.g. a composite of Mb, Ni, and Co. The catalyst may be supported on any suitable refractory inorganic oxide such as alumina, silica, zirconia, thoria, boria, titania, strontia, hafnia, and mixtures thereof.

Abstract: 1524054 Blow moulding articles with handles OWENS-ILLINOIS Inc 14 Oct 1975 [15 Oct 1974] 42021/75 Heading B5A An article having a handle, for example a container, is blow moulded from a pre-blown parison between a pair of mould halves provided with co-operating projections defining the non-blown area between the body of the article and the handle. During mould closure the parison is initially engaged over an area less than the non-blown area to secure it against movement relative to the mould and is engaged over the whole area only on mould closure. In one embodiment (see Figs. 4 and 5) a preblown preform 26 is blown to form a container between a pair of mould halves 20 each provided with a cavity 21 for forming the body of the container, a cavity 30 for forming the handle and an oval projection 31 defining the non- blown, and later removed, area between the handle and the body. Upon mould closure, a recessed region 28 of the preform is. first engaged by one end of the projection 31 only, the projection engaging the preform over its whole length upon subsequent movement to the closed position in Fig. 6. In a second embodiment, see Fig. 12, each mould half is provided with a pin 46 biased by a spring 50 to a projecting position. Upon mould closure, the preform is first engaged by the pin, and it is only upon further mould closure that the preform is engaged by the projection 43.

Abstract: 1,120,413. Measuring displacement of movable members. ING. C. OLIVETTI & C. S.p.A. 8 Oct., 1965 [8 Oct., 1964], No. 42721/65. Heading G4H. Apparatus for measuring the displacement of a movable member B (Fig. 1) with respect to a fixed member 1 comprises a counter 10 the contents of which are converted into analogue form and continuously compared with the analogue position of the movable, member to supply an error signal to control the counter. The counter may operate with different counting speeds depending upon the speed of displacement of the movable member. In the form shown the movable member is fixed to the secondary winding 5 of a position measuring transformer T. The number in the counter 10 is fed in binary coded decimal form to a digital to analogue converter 9 receiving A.C. clock pulses from an oscillator 12 so that on output leads 7, 8 sinusoidal signals having maximum amplitudes proportional to the sine and cosine of the angle represented by the count in the counter 10 are obtained. These signals induce on output terminal 13 of the transformer T a sinusoidal signal having a maximum amplitude proportional to the difference between the position of the movable part and the position represented by the digital information in the counter. This analogue error signal is applied to a threshold circuit 23 (which determines the error sensitivity level for the apparatus) to trigger a bi-stable element 32 if an error signal higher than the threshold level is revealed. The signal is also applied to a separator circuit 22 which supplies the positive and negative half waves of the error signal on its output terminals 22S and 22N respectively to gates 26, 27 controlled by clock pulses to energize or deenergize respectively a bi-stable element 31 to give an output on lead 33 or 34 respectively If the error signal is higher than the sensitivity level of threshold circuit 23 gates 36, 37 are enabled to pass a signal from bi-stable element 31 on either lead A or lead I to indicate a forward or backward count in the counter 10. The error signal on lead 13 is also fed to a further threshold device 21 which is triggered if the difference between the position represented in the counter and the actual position of the movable member is greater than 0À1 mm. to give an output on either lead 21S or 21N to indicate whether the counter should count in units or tens. The counter 10 may comprise more than two decades, a corresponding increase in the number of threshold circuits 21 being then necessary. A further counter 42 is incremented by the pulses applied to counter 10.

Webs of glass or other fibrous material are formed by deposition of the material first on one conveyer and then on to a second moving more slowly than the first, the belts being so disposed in succession that fibres are separated as they fall from the first belt to the second. As shown, a stream of glass fibres that have been deposited on a conveyer 13 from stapling rollers is allowed to fall off the conveyer on to a second conveyer 14. The speed ratio of the two conveyers may be 10: 1. Both conveyers may be foraminous and may have suction boxes beneath their operative runs. Separation of groups of fibres into individual fibres may be assisted by an air jet from channels 22 that direct the jet tangentially to the belt 13 as it passes over a roller 17. Before falling on to the first conveyer, the fibres will previously have had a binder applied to them and the second conveyer may pass through an oven.
