Title: Thermoplastic compositions
Inventor: SAUL WALTER
IPC: C08J3/20
Filed: 1950-11-30
Abstract: Plasticized polyvinyl compound compositions are made by grinding a finely divided polyvinyl compound with a liquid plasticizer, e.g. tricresyl phosphate, without heat until a particulate substantially dry powder is obtained.  If desired the composition may be heated at a temperature below that at which gelling takes place in order to effect adsorption of the plasticizer without coalescence of the particles.  The resulting composition may subsequently be sintered and then re-ground to a crumb-like condition.  The composition may contain fillers, e.g. titanium dioxide, and pigments.  The polyvinyl compound may be polyvinyl chloride or a copolymer of vinyl chloride and vinylidene chloride and/or vinyl acetate.  The composition may be used for coating plywood, synthetic resin sheets, layers of paper impregnated and bonded with a phenolic resin, or made into self-supporting sheets.  The products may be used for covering walls or table tops.

Title: Improvements in or relating to automatic weighing machines
IPC: G01G13/00
Filed: 1926-11-23
Abstract: 281,468. Avery, Ltd., W. & T., (Jamieson, J. A.). Nov. 23, 1926. Automatic-feed weighers.-In an automatic weighing-machine for weighing granular or pulverulent material the usual knock-off lever for the discharge gate of the weigh hopper is connected to a pendulous bar the movement of which is arrested during the initial stage of the discharge so as temporarily to restrict the movement of the knock-off lever and thereby temporarily to limit the degree of opening of the discharge gate thus moderating the rate of discharge and thereby obviating violent movements of the weighbeam and shock to the mechanism. The weigh hopper 3 mounted on one end of the weigh beam 4 is provided with a pivoted discharge gate 6 connected by a link 7 to an arm 8a formed integral with the knock-off lever 8 fulorummed on the side of the weigh hopper as usual. The arm 8a is also connected by a link 10 to a pendulous bar 11 pivoted upon the weigh hopper. A U-shaped spring 13 is bolted to the frame. In operation, when the weigh hopper descends after receiving its charge a projection on the frame knocks up the end of the knock-off lever 8 as usual and the pendulous bar 11 swings into contact with the spring 13 thus permitting the discharge gate 6 to open to a partial extent as shown. When sufficient material has escaped, the weigh hopper rises, the pendulous lever 11 rises above the spring 13 to continue its swing, the discharge gate opens fully and the further upward movement of the weigh hopper is cushioned by the usual buners 5.

Filed: 1935-10-28
Abstract: 458,285. Railway signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and BROWN, A., 63, Aldwych, London. Oct. 28, 1935, No. 29701. [Class 105] A railway signalling system with axlecounting apparatus operated by quick-acting light treadles is prevented from being accidentally operated by a workman stepping on such a treadle, by providing an associated heavy treadle which only when depressed by the train opens a contact in parallel with the light-treadle contact. Thus an operation only of the light treadle will not give an impulse " break " to actuate the axle-counting apparatus.
Patent GB-702360-A (GB)
Title: Improvements in and relating to the production of p-xylene
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C5/41
Filed: 1951-12-19
Abstract: p-Xylene is produced by contacting a diene containing the carbon skeleton <FORM:0702360/IV(b)/1> in the vapour phase and at 300-750 DEG C. with an aromatization catalyst, for example a metal of Group 8 or oxides of Cr, Mo or V, if desired with metallic oxides such as alumina and magnesia. Chromic oxide on alumina, desirably containing magnesium chromate, and platinum on charcoal are preferred.  Suitable dienes are 1, 1, 4, 4-tetramethyl-butadiene and 2, 5-dimethylhexa-1, 5-diene.  The process may be continuous using an inert gas as carrier for the diene which is suitably fed at .01-1 1. of liquid/l. of catalyst space /hr.  The diene is preferably produced from 2, 5-dimethylhexane-2, 5-diol obtained by condensing acetone and acetylene in the presence of potassium hydroxide or alkoxide, and hydrogenating the -yne-diol formed.  The diol is converted to diene by: (1) catalytic vapour phase dehydration, preferably at 250-600 DEG C.; (2) conversion to a di-ester and thermal decomposition at, for example, 350-600 DEG C.; (3) dehydration with a dehydrating agent, e.g. phosphoric or hydrochloric acid at 50-100 DEG C., to give 2, 2, 5, 5-tetramethyl tetrahydrofuran and further vapour phase catalytic dehydration of this, e.g. at 200-600 DEG C.; or (4) conversion to the dichlor derivative with HCl and dehydrochlorination with an organic base.  The tetrahydrofuran derivative also formed is converted as in (3).  Examples describe the conversion of 2, 5-dimethylhexane-2, 5-diol to dienes by dehydration over aluminium phosphate at 350 DEG C. or by esterification with acetic anhydride and decomposition of the di-acetate at 590 DEG C., and conversion to p-xylene over chromic oxide-alumina at 550 DEG C.  Specification 702,332 is referred to.ALSO:A chromic oxide-alumina catalyst is prepared by dehydrating alumina trihydrate at 400 DEG C. to a water content of 9-11 per cent. pelleting, if necessary removing the pelleting lubricant by calcining at 700 DEG C., immersing in chromic acid solution, and heating at about 400 DEG C.  The content of chromium oxides is desirably 10-15 per cent.  Magnesium chromate equivalent to, for example, 2 per cent. MgO, may be incorporated.

Title: Process and apparatus for carrying out electrolyte processes, more particularly those with decomposable end products, such as for instance the manufacture of persulphuric acid or of its salts by electrolysis
IPC: C25B9/19
Filed: 1930-10-04
Abstract: 362,579. Electrolysis. OESTERREICHISCHE CHEMISCHE WERKE GES., 5, Technikerstrasse, Vienna. Oct. 4, 1930, No. 29733. Convention date, Feb. 20. [Class 41.] In a two - compartment cell for the manufacture of persulphuric acid and its salts and like easily decomposable products by an anodic oxidation process, the anolyte passes through the cell at high speed in a thin layer, while the catholyte on the opposite side of the diaphragm passes slowly through the cell as a cooled column. In the apparatus shown the anolvte enters the anode chamber at the bottom of a glass tube 6 around which is mounted a closed glass vessel 5 which nearly fills the anode chamber. The anolyte then flows upwards in a thin stream between the vessel 5 and the diaphragm vessel 3 which it leaves at 4. The vessel 5 is supported on a plate 21 having a central opening and a radial slot to allow egress of the anolyte from the tube 6. The catholyte moves slowly through the outer chamber which is cooled by a lead pipe 14 which constitutes the cathode. The cooling fluid on leaving the pipe 14 is led by a tube 20 to cool the vessel 5, which it leaves by an overflow, not shown. The anode may consist of thin strips of platinum reinforced by strips of tantulum secured to a lead ring 9 ; the ring is provided with an ebonite covering which may extend partly over the strips. The diaphragm may be of unglazed porcelain, clay, gurocel, fabric or an artificial resin. The container may be of lead or a lead alloy or may be composed of or impregnated with a natural or artificial resin. Several cells may be connected in cascade, the anolyte and catholyte passing in succession through their various compartments ; a number of such series may be connected in parallel. In a modification several anode compartments are mounted in a single cell and surrounded by a common coil-shaped cathode; several of such cells may be arranged with all the anodes connected to the common cathode of the preceding cell, the anolyte flowing from each compartment to the corresponding compartment of the next cell, and the catholyte from each outer compartment to that of the next cell. Liquid containing persulphuric acid or its salts obtained by this method may be treated by hydrolytic decomposition for the manufacture of hydrogen peroxide, after removal of which it is passed through the cathode chambers before return to the anode chambers. Detailed examples of dimensions and current densities are given.

Title: Process for regenerating used alkaline reagents
Inventor: GLEIM WILLIAM KARL THEODORE
IPC: C10K1/12
Filed: 1958-09-19
Abstract: A process for the regeneration of solutions of sodium or potassium hydroxide which have been used for the treatment of liquid or gaseous organic compounds to remove acidic components therefrom, particularly a thus used aqueous solution of sodium hydroxide or potassium hydroxide, comprises subjecting the solution to an oxidising treatment by contacting with air or other free oxygen-containing gas in the presence of a catalyst comprising a metallic or metal-free phthalocyanine or a derivative thereof and thereafter separating the oxidation products of the acidic components from the solution. Specified catalysts referred to are phthalocyanines per se, a phthalocyanine containing one of the metals, Fe, Cu, Mg, Zn, Ti, Hf, Th, Su, Pb, Cm, Ta, Bi, Cr, Mo, Ni, Pd, Pt, Ag, or Hg, but preferably those containing Co, Mu, or V, or mixtures thereof.  Derivatives referred to are carboxylated or sulphonated compounds of any of the above. Aqueous solutions of sodium or potassium hydroxide of 5-50% weight concentration, containing, if desired, solutizers or solubilizing agents such as methanol, ethanol, phenols, cresols or butyric acid, and containing absorbed acidic components e.g. mercaptans, from the treatment of hydrocarbon fractions e.g. sour gasolines including straight run and cracked gasoline or mixtures thereof, naphtha, jet fuel, kerosine, aromatic solvent, stove oil, range oil, burner oil, and distillate fuel oil, as well as normally gaseous hydrocarbon fractions, or from treatment of other organic materials containing acidic impurities e.g. alcohols, ketones and aldehydes, are subjected to an oxidising treatment by agitating the solution with air or other free oxygen-containing gas in the presence of the catalyst which may be present in proportions 0.0001%-20% weight of the sodium or potassium hydroxide and may be dissolved in the solution or suspended therein deposited on a suitable solid carrier e.g. charcoal, or alternatively be used in contact with the solution deposited on a carrier as a fixed bed. When the catalyst is dissolved in the solution it may remain therein during both treatments of the organic compounds to remove acidic components and regeneration, the treatment to remove acidic components however in such an instance being effected in the absence of oxygen.  The oxidation may be effected at ambient temperature or above, preferably at temperatures not exceeding 95 DEG C.  After oxidation the acidic impurities may be removed from the regenerated alkaline solution by skimming or liquid extraction with a suitable solvent e.g. solvent naphtha. Alternatively, the regeneration may be improved by the addition to the solution of an immiscible liquid capable of dissolving precipitated oxidised organic sulphides e.g. thio phenol, such liquid containing dissolved impurities then being removed by decantation.  After oxidation the purified solution may be filtered to remove entrained solid catalyst and carrier, if present, and the regenerated solution re-used as desired.
