Title: Improvements relating to the desulphurisation of gases and vapours
Inventor: REEVE LEWIS
IPC: C10K1/30
Filed: 1958-01-24
Abstract: In a process for removing sulphur compounds from the vapours of hydrocarbon liquids, e.g. gas oils, the vapour is passed through one or more fluidized beds of particles of an oxide such as iron, manganese or zinc oxide and the sulphur content in the bed or beds is maintained below 10% and preferably below 2% by the continuous withdrawal for regeneration of oxide from the bed or beds and the return thereto of regenerated oxide.  The oxide is regenerated by heating under oxidizing conditions and the rate of circulation between the absorber and regenerator is such that the whole mass of oxide in the absorber is changed at least once every 4 hours and preferably at least once every hour.  Specification 719,056 is referred to.

Title: A process for the production of metals by reduction
IPC: C22B34/14
Filed: 1957-01-25
Abstract: Metals of Groups IV(a) and VI(a) of the periodic table, especially Ti and Zr, are obtained by reducing their halides (preferably the chlorides) which are solid under normal conditions with alkali metal or alkaline earth metal hydrides especially Li or Ca hydrides, at elevated temperature.  The reaction temperature is preferably higher than the melting temperatures of the alkali metal or alkaline earth metal halides (e.g. CaCl2) being formed, and the reaction may be carried out in hydrogen.  Thus Ti subchlorides are reacted with CaH2 in a hydrogen atmosphere at 800-900 DEG C.; ZrCl4 is similarly treated.
Patent GB-371888-A (GB)
Title: Improved process for the recovery of sulphur dioxide from gas mixtures containing it
IPC: C01B17/60
Filed: 1931-01-29
Abstract: Sulphur dioxide is recovered from gas mixtures containing it by washing them with a substantially anhydrous solvent consisting of aniline or its homologues or N-alkyl derivatives of aniline or their homologues or mixtures thereof, the used solvent being regenerated by the application of heat and reduction of pressure, whereby concentrated sulphur dioxide is obtained.  The washing may be effected under increased pressure, say 10 atmospheres, and at as low a temperature as possible without the solvent congealing. The gases to be treated should preferably be preliminarily dried for example by washing with concentrated sulphuric acid.  The absorbed gas may also be set free by passing an inert gas or steam through the used solvent preferably at raised temperature.  An example describes the absorption of sulphur dioxide by passing gases up a tower in counter current to a mixture of aniline with dimethyl aniline, the used solvent being recirculated after treatment with inert gas or steam in another tower.  Traces of solvent may be removed from the gas by passing it over active charcoal.  According to the Provisional Specification the aniline derivatives may be mixed with non-volatile organic solvents such as paraffin oil, creosote oil or vegetable oils, an example being dimethyl aniline mixed with paraffin oil.

Title: Improvements relating to articles of ceramic bonded granular material and a method of making the same
IPC: B24D3/18
Filed: 1935-01-29
Abstract: In the manufacture of articles such as grinding wheels, porous plates, tiles, and refractory bricks from granular, particularly refractory, material and a ceramic bond, the amounts of grains, raw bond, water, and gas which will give the desired proportions of grains, bond, and pores in the final product are predetermined, these amounts of grains, bond, and water are mixed, and the predetermined quantity of gas is entrained, dispersed, and stabilized in the fluid mass which is shaped, dried, and fired. To obtain the required pore volume, the wet mix may be beaten or otherwise treated to disperse gas bubbles uniformly therein to give a mix of a density which is pre-calculated to give the required density after firing.  The bubbles are stabilized by means of sulphonated castor oil, saponin, licorice, soap tree bark, or the like.  According to examples: (1) water is added to a mixture of alumina with a bond comprising ball clay, slip clay, and felspar, and sulphonated castor oil, the mass is stirred to introduce air and form a foam; (2) a mixture of alumina, clay-felspar bond, and licorice solution is employed; (3) silicon carbide replaces alumina and saponin the licorice solution; (4) a water extract of soap tree bark replaces the sulphonated oil of (1); (5) a magnesium-aluminium spinel is bonded with felspar and clay, or beryl with sodium silicate, zinc oxide, and clay. Specifications 363,192 and 384,854 are referred to.  The Specification as open to inspection under Sect. 91 refers to the use of an aqueous extract of sawdust for stabilizing the gas bubbles.  This subject-matter does not appear in the Specification as accepted.

Title: Method for preparing a yeast extract
Inventor: ISHIDA KENGO
IPC: A23L27/10
Filed: 1970-01-21
Abstract: 1278561 Yeast extract KYOWA HAKKO KOGYO CO Ltd 21 Jan 1970 [8 Feb 1969] 2984/70 Heading A2B [Also in Division C3] A method for preparing yeast extract involves decomposing yeast with at least one cytolytic enzyme produced by a microorganism belonging to the genus Coprinus, Daedaleopsis or Irpex and recovering the extract. The extract so obtained may then be treated with a commercially available protease preparation to increase the amount of amino acids formed. The cytolytic enzyme may be obtained by aerobically cultivating Coprinus macrorhizus f. microsporus, Coprinus radians, Coprinus micaceus, Daedaleopsis styracina, Daedaleopsis confragosa, Daedaleopsis tricolor, Daedaleopsis nipponica or Irpex lacteus and recovering the crude enzyme from the culture liquor by precipitation with acetone or ammonium sulphate, electrodialysis and freezedrying. Alternatively, the cells or culture filtrate containing the enzyme may be employed. Such yeasts as bakers' yeast, alcohol waste liquor yeast, sulphite waste paper liquor yeast and petroleum yeast may be subjected to the decomposition treatment. Preferably the cells are first killed by strong heating. Ethyl acetate and alcohols can be included as preservatives, if necessary. The decomposition liquor is filtered and contacted with activated carbon, ion exchange resin or non-ionic exchange resin. The taste and flavour may be adjusted by addition of sodium 5'-inosinate, sodium glutamate, and amino acids and other organic acids. Reaction (ageing) between the sugars and amino acids is promoted by adjusting the pH to between 5 and 6.5 and heating at 40-85‹C. The aged seasoning liquor may be concentrated and spray-dried.

Title: Improvements relating to variable leverage mechanism for fluid pressure braking apparatus for railway and other vehicles
IPC: B61H13/32
Filed: 1951-02-09
Abstract: 693,020. Brake mechanism. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and BRACKEN - BURY, A. G. Jan. 11, 1952 [Feb. 9, 1951], No. 3199/51. Class 103 (i). A variable leverage mechanism for railway vehicle brake rigging of the kind in which a fulcrum 23 against which the brake lever 20 may pivot, is movable along a track 23 in accordance with  the vehicle load, is characterized in that the fulcrum track is formed on a lever 21 which is itself pivotable away from the brake lever 20 when in the brakes released position, so as to allow a completely free adjustment of the position of the fulcrum. The mechanism is shown in Fig. 1 in the braked released condition in which the lever rests against a fixed abutment 5 formed integral with the lever 21. When the brake cylinder is actuated, rod 18 is moved to the right so that the lever 20 first pivots about the abutment 5 before engaging the fulcrum 23. At the same time an angled lever 14 is also moved to the right so that the roller 12 carried at its end is moved upwardly between the inclined surface 13 on the back of lever 21 and a surface 8 on a fixed member 10, thus causing lever 21 to pivot anti-clockwise about its fixed pivot 15. Fig. 3 shows the mechanism in a position corresponding to a movement of the piston in the brake cylinder sufficient to just cause the brake blocks to bear against the wheels. It is arranged that this degree of movement shall cause the surfaces 25 and 22 on levers 20 and 21 to become parallel so that any additional pressure applied to the brake blocks is as a result only of the pivoting of lever 20 about fulcrum 23. In this position also the roller 12 is also disposed between parallel surfaces and does not cause any further movement of the lever 21. On the release movement a spring 6 pulls back the lever 21 as the roller 12 is run down so that on full release the lever 20 bears on the abutment 5 and is once more clear of the fulcrum 23. Modified arrangements are described in which the abutment 5 is replaced either by a fixed abutment not forming part of lever 21, or by the end of a slot formed in an extension of the lever 21. In a further embodiment, as shown in Fig. 7, the pivotal movement of the lever 21 about its fixed pivot 15 is brought about by the brake rod 18 causing the pins 37 to move up or down an inclined slot 36 in a fixed bracket 35 thus straightening or collapsing toggle arms 20, 31. The manner in which the fulcrum 23 is adjusted according to load may be as described in Specification 687,515.
