Patent GB-862985-A (GB)
Title: Catalytic olefin polymerization
IPC: B01J23/26
Filed: 1957-11-05
Abstract: A polymerization catalyst comprises chromium oxide deposited on a silica-alumina gel having a surface area of at least 450 sq.m./g. and an average pore diameter of at least 65  , at least part of the chromium being in the hexavalent state.  The average pore diameter (D) is calculated from the formula D = 4V/S, where V is the pore volume and S the surface area.  The alumina content of the gel is generally below 50% wt. and preferably 2-30% wt.  The gel may also contain other oxides, e.g. zirconia, thoria and/or magnesia.  One method of preparing a gel having the specified properties is to acidify an aqueous solution of sodium silicate to form a hydrosol, gelatinize the hydrosol to a hydrogel, add sufficient aqueous aluminium sulphate to provide the desired alumina content, render the mixture alkaline with ammonia, spray-dry the precipitated silica-alumina and wash with water. The chromium oxide may be incorporated by mixing the dry or suspended oxides or by treating the silica-alumina with chromium trioxide or a chromium compound which is converted to chromium oxide by heating, e.g. ammonium chromate, chromic nitrate, chromic acetate or chromium sulphate.  The impregnated composite should be dried, e.g. at up to 300 DEG F., and activated in a dry, non - reducing atmosphere, e.g. nitrogen, oxygen, helium or argon, at 450 to 1500 DEG F.  The hexavalent chromium content after activation is ordinarily at least half the total chromium content, which may be from 0.2 to 50% wt. of the total catalyst.  Specification 790,196 is referred to.

Title: Optical communication system
IPC: G02B6/34
Filed: 1973-07-19
Abstract: 1387981 Optical communications systems STANDARD TELEPHONES & CABLES Ltd 19 July 1973 34455/73 Heading G1A In an optical communications system components of the output from a length of optical fibre are separately detected and the resulting signals combined after passing through suitable delays to compensate for different propogation times of the components. In a first embodiment, Fig. I, the output of a multimode optical fibre 14 is directed on to an I.C. photo-detector comprising a central detector area 11 surrounded by an annular detector area 12. The output of detector 11 is delayed before it is combined with the output of detector 12 to compensate for the dispersion of pulses due to the increase in propogation time with increase in angle of propogation. The amount of the delay depends on the properties of the fibre and its length. Further annular photo-detectors may be used with suitably proportioned delays. In a second embodiment Fig. 2 (not shown) a single mode fibre is compensated for spectral dispersion by passing the output through a  collimating lens (21) to a prism (22), a second lens (23) focusing the spectrum on to a linear array of three photo-detectors (24, 25, 26). The outputs of two of the detectors are delayed by different amounts before being combined with the output of the third detector to compensate for differences in propogation speed with wavelength.

Abstract: 340,374. Loud-speakers &c. ALLEN, G. T., Kingsmead Hotel, Eastern Esplanade, Broadstairs, Kent. Nov. 14, 1929, No. 34812. [Class 40 (iv).] In a loud-speaker or like sound-reproducing apparatus of the kind in which a flexible diaphragm is held under tension in a frame or baffle board, means are provided for varying the tension at different points of the diaphragm by forming therein a series of radial corrugations or undulations, the material along the crests of which is placed under greater tension than the material at the other portions of the diaphragm. In the construction shown the diaphragm 2 is secured at its edges to an outer frame 1, inside of which is arranged an inner frame 5 carrying on its rear face a number of projections 6 adapted to form the corrugations in the diaphragm. These corrugations may be spaced apart regularly or irregularly, and may be of uniform or varying heights, but preferably a large projection is disposed at each corner of the frame, while the pressure of the projections on the diaphragm can be adjusted by arranging the inner frame 5 to be slidable in the outer frame, e.g. by projections 5<a> on the inner frame working in slots in the outer frame. Further corrugations may be produced by the addition of a still smaller frame 8 having projections 9 pressing on the opposite side of the diaphragm to the projections 6. For adjustment purposes the frame 8 is positioned by means of two rails 10 passing over screw-threaded posts 11. In addition, the rails 10 may themselves be fitted centrally with a pair of posts 13 along which the loud-speaker unit 4 and armature rod 3 are adjustable. In a modification, the projections 6, instead of being arranged on a separate movable inner frame, are arranged directly on the outer frame, which is thereby given an irregular contour, and, if desired, an auxiliary frame of corresponding contour may be provided for clamping purposes. In the case of double-diaphragm instruments separate frames or sets of frames are associated with each diaphragm.

Abstract: 341,616. Reduction of grain. GELINCK, W. V., 2, Babelsbergerstrasse, Rehbr³cke, near Potsdam, and FAHRENHORST, W., 60, Grunerstrasse, Dusseldorf, both in Germany. Nov. 14, 1929, No. 34859. [Classes 5 (i) and 58.] Dough is produced from unmilled softened grain by passing the grain to a disintegrating apparatus furnished with cutting blades, under pressure, which, however, is not sufficient to cause the grain to be crushed or to remove the husk or bran from it before it reaches the cutting blades. The grain is fed from a hopper 26, Fig. 1, to a housing 3 and is moved forward to the cutting zone by worms 4, 5, Fig. 2, rotating in opposite directions where it passes successively through screens 18, 19, 20 and is cut by star-shaped knives 30, 31, 32 mounted on the worm shafts. The front faces 14 of the worms are cut perpendicular to their axes so that there is no tendency to move the grain radially and bruise it against the casing. Recesses 25 provided in the inner walls of the housing 3 allow the grain to reach the outer perforations of the screens ; these may be formed helically and increase in area as the cutting- zone is approached. The grain is subjected to pressure before being cut, by a suitable restriction of space between the successive threads of the worms. The dough discharges through a removable hopper 15 clamped in position by a ring 17.
