Filed: 1954-10-06
Abstract: 804,462. Aerials. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 19, 1955 [Oct. 6, 1954], No. 28731/54. Class 40 (7). An aerial designed to operate in two frequency bands comprises spaced conductive elements interconnected through time delay means having different time delays in the different bands so that signals from the two elements in both of the frequency bands are added at the feeder. In one embodiment (Fig. 1) four elements 1, 2, 3 and 4 are arranged in double V formation with the apices of the V's adjacent to each other. Elements 1 and 4 and 2 and 3 are connected together through time-delay means comprising inductances'7, 8 and capacitors 9. The feeder 10 is connected to the elements 1, 2, through a matching circuit consisting of units 11, 12, 13. The length of the elements 1, 2, 3, 4 may be a quarter of a wavelength (or an odd multiple thereof) at the lowest frequency. Instead of employing lumped impedances in the delay means a length. of transmission line, provided with short-circuiting stubs as necessary, may be used (Fig. 6, not shown). To increase the bandwidth of the aerial the elements 1, 2, 3 and 4 may be coupled at their outer ends to similarly disposed additional elements la, 2a, 3a and 4a connected together in pairs through resistors 16 and 17 equal to the characteristic impedance of the elements. The resistors may be omitted and replaced by direct connections though this results in some sacrifice in bandwidth. In an aerial consisting of two unipoles 1 and 3 (Fig. 9) the time delay means is inserted between them and artificial earths 23 and 24 of suitable lengths for frequencies in the two bands provided. The coaxial feeder is connected between element 1 and the artificial earths 23, 24.

Patent GB-682400-A (GB)
Title: Improvements in filters
IPC: B01J20/22
Filed: 1949-11-11
Abstract: A filter medium of the edge filtration type comprising a pile of annuli or strips of paper made substantially of material having hollow fibres is lightly impregnated with a water-proofing material so that only a small proportion of the hollow fibres are filled to render the paper discs or strips resistant to loss of identity when wetted, while enabling the remainder of the hollow fibres to absorb their maximum capacity for water.  Columns or piles of annular discs of paper made from 80-90 per cent of hollow fibre material such as cotton, linen or ramie are each mounted on a perforated tube carried on a tube plate in a jacketed vessel, the pressure being reduced to 1 inch of mercury by a vacuum pump.  The vessel is then filled with a non-solvent for nitro-cellulose such as methyl alcohol or carbon tetrachloride and the interior of the fibre discs allowed to become completely impregnated for 15 to 20 minutes.  The vessel is then connected to the atmosphere and the liquid drained off.  Subsequently the vacuum pump is utilized for filling the vessel with a solution of nitro-cellulose, ethyl lactate, acetone and methyl actone.  After about 10 to 15 minutes the nitro-cellulose is drained off and hot water passed through the jacket of the vessel to raise its temperature to 60 DEG C, whilst the vacuum pump is operating.  When liquid ceases to flow from a condenser on the exit side of the pump the prepartion of the filter medium is complete.  In use a number of impregnated leaves are assembled around a perforated column to form a pack which is installed in a liquid filled vessel.  Heavier liquid and foreign matter rejected by the filtering medium may fall to the base of the vessel for removal under automatic control such as by a float operating valve or by a solenoid plunger with electrical contacts, or the collected solid may adhere to the outer edges of the discs and be dislodged by reversing the flow of clean liquid or by applying compressed gas to the interior of the perforated column. The end pressure on the pile of annuli or strips, the degree of impregnation, and the maximum supply pressure imparted to the liquid to be filtered, which may be oil, may be adjusted so that the increase in volume of the pile when it is fully saturated with water is sufficient to prevent further passage of any liquid.

Title: Improvements in or relating to apparatus for the preparation of cellulose xanthate
IPC: D01F2/08
Filed: 1929-09-26
Abstract: 337,149. Dassonville, M. July 1, 1929, [Convention date]. Rotary mixers.-Apparatus for the production of cellulose xanthate comprises a pair of hermetically fitting double jacketed caps of spherical calotte form with smooth internal surfaces, the caps being supported on journals and arranged so that they can be moved axially with respect to one another for discharge and cleaning purposes. The caps thus form a jacketed churn which is slowly rotated during the reaction of carbon bisulphide on the charge of alkalicellulose. The construction enables the temperature of the reacting mass to be continuously controlled and results in a more homogeneous product. Carbon bisulphide may be fed in through one of the journals and the cooling or heating fluid circulating in the jacket may also be fed through the same journal. In the drawings, the spherical caps 1 and 1<b> are assembled as shown; the connecting joint 2 made between conical members held by nuts and bolts 17<a> renders the apparatus fluid-tight. Each cap is provided with a double jacket 3, continuity being established between the jackets by means of the flexible tubes 4, even during the opening of the apparatus. The poles of the caps are provided with flanges secured to journals 7 and 8. The churn is given a slow revolving motion by means of a worm-wheel 11 and a worm 12 on the shaft of fast and loose pulleys. Removable distance pieces 17 which normally engage beneath the heads of the bolts 17<a> define and limit the linear motion of the caps for discharge and cleaning purposes. This motion is provided for by the hand-wheel 22 and gears 20 and 21 which may rotate the axially fixed nut 19 meshing with the square threaded screw 18 on the journal 8. During the rotation of the chum, the pinion 21 is disconnected. Carbon bisulphide is supplied under pressure from the gauging device 26 through a central conduit in journal 7. At the end of the reaction the carbon bisulphide vapours are sucked out of the churn through the funnel 27 connected by means of conduit 25 and a pump to a recovery apparatus. Internal ribs or baffles 29 are dipsposed in the jacket 3 to control the circulation of the heating or cooling fluid which may be made to pass from one half of the axially fixed cap to the movable cap and then back through the other half of the fixed cap. The inlet and outlet conduits leading to and from the connections 34 and 35 of the double jacket pass through the journal 7. Manholes 36 for facilitating the loading of the apparatus are provided in the caps, and the process is observed through sights 37.

Filed: 1964-07-17
Abstract: In the production of hydrogen peroxide by the catalytic hydrogenation of alkylanthraquinones or mixtures thereof with tetrahydroanthraquinone and/or tetrahydroalkylanthraquinones in organic solvents, oxidation of the resultant alkylanthrahydroquinones or mixtures thereof with tetrahydroanthrahydroquinone and/or tetrahydroalkylanthrahydroquinones, and extraction of the resultant hydrogen peroxide, the hydrogenation catalyst is obtained by leaching a nickel-aluminium alloy, which leaching includes treatment with aqueous alkali solution at a temperature of from 120 DEG  to 160 DEG C.  The treatment preferably is carried out for between 1 and 3 hours at a temperature of from 130 DEG  to 150 DEG  C. To prevent deposition of aluminate on the catalyst, the leaching may take place in two stages, a fresh solution of alkali being used in the second stage, which is operated at a temperature of from 120 DEG  to 160 DEG C. to constitute the above treatment.  As exemplified, nickel-aluminium alloy is first leached by 20% by weight aqueous caustic soda solution at the boiling point (105 DEG  to 107 DEG  C.) of the solution for 1 hour and, after removal of the aluminate-containing solution by decanting, is further treated under pressure with fresh aqueous sodium hydroxide solution having a specific gravity of 1.24 for 2 hours at a temperaure either of 130 DEG  C. or of 140 DEG  C. The subsequent catalytic hydrogenation step in the production of hydrogen peroxide preferably is carried out at a temperature of from 40 DEG  to 65 DEG  C.; the working solution may comprise a mixture of alpha-methylnaphthalene and sec-octanol solvent containing 2-ethylanthraquinone (2-EAQ) and tetrahydro-2-ethylanthraquinone (TH-2-EAQ) (Example 1); 2-EAQ, TH-2-EAQ and tetrahydroanthraquinone (Examples 2 and 4); or 2-EAQ, TH-2-EAQ and tetrahydro-2-methylanthraquinone (Example 3).
