Abstract: 1,142,379. Fluid pressure control valves &c. W. ODENDAHL. 24 Oct., 1966 [25 Feb., 1966], No.47599/66. Heading F2V. [Also in Division G3] Within the housing 4 of a throttling device there is disposed a cylindrical plug 3 whose outer surface has formed on it a set of straight, non-helical grooves 7, the inclination of these being such that fluid entering between the shaft 1 and body 4 is directed into a ring channel 6 of the housing 4. A ring vortex 10 is consequently formed within this channel and serves, on account of its core 11 not touching the walls to reduce erosion and cavitation of the wall. Fluid from the vortex leaves the device through an annular ring 13, the quantity of fluid passing through the device being governed solely by the relative disposition of the plug and housing, with complete-cut-off occurring when the shaft face 2 engages the housing seat 5. Figs. 3-8 (not shown) depict various modifications of this basic embodiment, such as e.g. an extended plug having two sets of spaced and oppositely inclined grooves, each having its own separate ring channel and therefore ring vortex, or a modified ring channel housing two ring vortices of opposite rotation which are supplied by fluid from two opposed inlets each having disposed within it one end of a grooved plug.

Title: Improvements in or relating to the Fractionation of Hydrocarbons
IPC: C07C7/13
Filed: 1968-10-11
Abstract: 1,192,845. Fractionating hydrocarbons. COMPAGNIE FRANCAISE DE RAFFINAGE. 11 Oct., 1968 [12 Oct., 1967 (2)], No. 48235/68. Heading C5E. In a method of fractionating mixtures of hydrocarbons containing olefins having e.g. from 4 to 8 C atoms per molecule, by means of molecular sieves, the sieves are neutralized by impregnating them with a solution of a strong inorganic base, e.g. sodium, potassium or lithium hydroxide, and desorbing the hydrocarbons adsorbed on the sieves. The solution may be aqueous or alcoholic, e.g. methanolic, and desorption is effected by lowering the pressure or raising the temperature on the sieve, or by sweeping the sieve with an inert gas, or preferably by displacement of the adsorbed hydrocarbons by another adsorbent, e.g. propane or ethylene followed if desired by purging with an inert gas. The method is applicable to purifying iso-olefins of straight chain hydrocarbons, or diolefins, and may be effected in the liquid or gaseous phase, preferably at below 100 C. Specific examples describe the removal of butene-1 from a mixture of butanes and butenes, and the purification of isobutylene of butanes, butenes and butadiene. The method is cyclic, the purified feed being repassed over the regenerated sieve. Natural or artificial zeolites may be employed as sieves, and should have a pore diameter of 5 A, and the impregnated sieve should be initially washed, dried and calcined.

Title: Interferon purification
Inventor: FANTES KARL HEINZ
IPC: C07K14/555
Filed: 1963-12-10
Abstract: Material containing interferon is purified by the precipitation of unwanted protein from an aqueous solution thereof at a pH not greater than 5.0 by means of a water-soluble salt providing iodide or thiocyanate ions, the pH of the solution being adjusted, where necessary, to a pH not greater than 5.0 before, after, or simultaneously with the inclusion of said salt.  After removal of the unwanted protein, the interferon can be recovered from aqueous solution by precipitation using, for example, water-miscible alcohols or ketones.  The resulting interferon may be further purified by elution of a solution thereof on an anion exchange resin, e.g. diethylaminoethyl cellulose, which removes further protein.  The interferon material may be initially adsorbed on an alumino-silicate and it may be eluted therefrom by the aqueous thiocyanate or iodide solution.

Filed: 1972-10-24
Abstract: 1412650 Catalytic conversion UNIVERSAL OIL PRODUCTS CO 24 Oct 1972 48889/72 Heading B1F The invention relates to a method of catalytically converting a fluid e.g. I.C. exhaust gas in a converter containing a catalyst divided into a plurality of distinct zones of supported catalyst of predetermined depth measured in the direction of fluid flow through each zone the zones being spaced from each other by a predetermined distance also measured in the direction of fluid flow to provide a manifold upstream of each but the first catalyst zone, and an inlet manifold upstream of the first catalyst zone, the inlet manifold, the predetermined distance and the predetermined depth being such as to ensure that the fluid is introduced in a tubulant state into each zone and is withdrawn from each zone while the flow is not yet laminar, the fluid, apart from that exiting from the last zone, then being passed into the following manifold to intensify the tubulant state before entry into the next zone. The invention also relates to a method of fabricating a catalytic converter so as to minimise the amount of supported catalyst required therein and to maintain turbulence throughout the converter comprising steps of (a) determining the entry length (defined below) for the particular catalyst and flow conditions to be used, (b) dividing the catalyst into a plurality of spaced zones, each zone having a depth measured in the intended direction of flow no greater than the entry length, and spacing said catalyst zones from each other in the intended direction of flow by a distance sufficient to permit turbulence to be intensified upstream of each but the first catalyst zone. The "entry length" is defined as, equaling the beds to a tube, that portion of the length of tube in which the boundary layer grows to about 99% of but remains less than its equilibrium thickness. A reactor for the conversion process comprises catalyst supported on the surface of a plurality of spaced apart honeycomb support members, each defining a plurality of similar flow channels having internal diameters in the range of 1-5 mm, the spacing between the support members being 8-24 times the internal diameter of one of the flow channels, and the length of each flow channel being 8-32 times the internal diameter of the flow channel. Another reactor for the conversion process comprises catalyst supported on particles defining at least two separated particle beds, the equivalent diameter of the particles in each bed being 1-5 mm, the depth of each zone being 5-25 mm, and the spacing between adjacent beds being 10-50 mm. Another reactor for the conversion process comprises catalyst supported on fibrous mats, the spacing between mats being 10-50 mm, the depth of individual mats being 2.5-25 mm, and the opening between individual fibres or any mat being equivalent to or less than the diameter of the fibres comprising that mat.

Filed: 1971-12-10
Abstract: 1380054 Measuring web material P LIPPKE 10 Dec 1971 [10 Dec 1970] 49928/71 Heading G1M A web 9 to be tested is carried over a roller 10 or guide strip beneath a row of feelers 8 adjustably carried by a plate 7 bolted to a support 3 mounted on axles 5. The support 3 and axles 5 slidably keyed to a part 51 may be moved axially by a hand wheel 21 fixed to the shaft and threading on the part 51 which is an extension of a bush 22 eccentrically mounted in a rotatable sleeve 11. The sleeve 11 itself is concentrically mounted in a gear wheel 43 mounted in the machine side plates 6 and may be rotated by a handle 12 turning gear wheel 42 and the gear wheel 43 to which the sleeve is keyed. Rotation of the wheel 42 may be prevented by a locking plate mechanism 64, 61. Rotation of the sleeve 11 slightly lifts or lowers the axles 5 and the support 3 and adjusts the gaps between the feelers 8 and the web, and thus rotation may be gauged and set by a vernier scale (55), Fig. 3 (not shown) on the wheel 43 and on an arm (54) depending from a ring 53 rotatably mounted on a bush 44 integral with the wheel 43. A swivelling arm 14 clamped to and rotating with the bush 22 and axles 5 is pushed against a stop 20 by a compressed air cylinder 15 and prevents twisting of the axles 5 and if the arm is rotated by the cylinder 15 then the axles 5 and the support 3 are rotated also and the feelers 8 lifted right away from the web. In operation, irregularities such as thickening or creasing of the web causes the feelers 8 to pivot about (25), Fig. 2 (not shown) and complete the circuit of a signalling system through contacts (29) and (30). A locking device (36) enables a feeler to be tilted to and held in an inoperative position if so required.

Title: Improvements in or relating to waveguide filters
Inventor: CRAVEN GEORGE FREDERICK
IPC: H01P1/219
Filed: 1966-11-11
Abstract: 1,133,801. Waveguide filters. STANDARD TELEPHONES & CABLES Ltd. 11 Nov., 1966, No. 50573/66. Heading H1W. A waveguide bandpass filter comprises main resonant cavities coupled by sections which are evanescent (i.e. are dimensioned below cut-off) at the passband frequency of the filter. In the form shown, the cavities C, E, G are tuned by coarse and fine tuning screws 3, 4 and the bandwidth is adjusted by means of screws 5 which affect the cut-off frequency of coupling sections D, F, H. As an alternative to screws 5, the blocks 9 forming the coupling sections may be provided with transversely slidable sections (7, Fig. 10, not shown). The filter is terminated by inductive irises 6. The Specification contains a theoretical discussion of the behaviour of the filter and detailed information on design procedure. It is pointed out that the filter propagates freely at frequencies above the cutoff frequency of the coupling sections and that it is necessary to provide means for absorbing or reflecting parasitic signals at these frequencies. Thus, the coupling section 11, Fig. 15(b) is associated with a narrow-band rejection filter comprising three resonant stubs 13 tuned by pistons 14. This may be converted to an absorptive constant-resistance filter (Fig. 16, not shown) which uses a resonant stub and a stub containing a matched dissipative load. Another form of narrow-band absorptive filter comprises a resonant-slot hybrid junction 19, Fig. 18, coupling the evanescent section 18 to a circular waveguide 20 containing a load 21. In a modification of this arrangement, the coupling section contains a section bounded by irises resonant at the rejection frequency, this cavity being coupled by a hole coupler to an external resonant cavity containing a dissipative load. The coupling section may, in addition, be provided with a series rejection filter comprising a central transverse post 30, Fig. 23(b). This behaves as a reflector and is situated at a point beyond the absorptive filter. In another arrangement (Fig. 25, not shown), the coupling section contains a cavity resonant at the rejection frequency provided with a tuning screw and a dissipative iron-dust slug. A series rejection filter (see Fig. 23) is situated just beyond the resonant cavity. Instead of using resonant rejection filters, the evanescent coupling sections may be constructed to have the properties of low-pass filters. Thus, the coupling sections 38(a), 38(b), Fig. 31(b), incorporate corrugated low-pass filters having a cut-off frequency below the parasitic frequencies. An intermediate coupling section is provided with a dissipative stub 40.
