Title: Improvements relating to prepayment mechanism
IPC: G07F15/08
Filed: 1944-08-21
Abstract: 584,550. Prepayment mechanism for meters. MEASUREMENT, Ltd., CLIFFORD, C. F., and HILTON, F. Aug. 21, 1944, No. 15942. [Class 27] Price - change mechanism. In mechanism comprising a plurality of gear wheels k<1>-q<1> with any one of which a jockey wheel t can be selectively engaged, this is effected by a gear-setting knob 3, which is moved axially to break the gear mesh, and rotated to displace the jockeywheel into register, with the selected gear wheel. As shown the wheels k<1>-q<1> are of equal size and loose on a shaft r. Except for q<1> they are each fast with a wheel k-p of appropriate size meshing with respective wheels secured to shaft c' and providing the several gear ratios for the different price rates. The jockey wheel t is free on a spindle t' in a frame u mounted to rock on a shaft v, and is in permanent mesh with a long pinion w fast on the shaft. A spring x biasses the frame u to hold the jockey wheel against the wheels k<1>-q<1>, but the frame can be rocked to break the mesh by depressing the knob 3 whose spindle end seats in the frame. By turning the knob 3, the jockey wheel is then traversed along its spindle t<1>, to select the new gear through a pinion 8 and a rack 6 having lugs 4 embracing the boss of the wheel. A pawl 9 on the rack engages the jockey wheel to prevent its turning whilst the mesh is broken. In its raised position the knob is locked against rotation by engagement of notches in its dial plate 11 with a pointer 15 in a fixed locking plate 14, and unauthorized depression is prevented by a locking bar on a handle 17 sealed against rotation. The mechanism is duplicated as regards the jockey wheel t and adjusting elements, the two shafts v being connected through a summating differential to the quantity mechanism, and the two halves of the mechanism providing course and fine-adjustment. The shaft c' is connected through gearing b and a with the coin mechanism. Fig. 5 shows the invention applied to the gearing described in Specification 552,937. A bevel pinion 29 is mounted in a slide 32 which can be traversed by a helically grooved spindle 33 to engage the pinion with any one of a series of rings of teeth in a crown wheel 21. The slide 32 is first rocked about its spindle 34 to bring the pinion 29 clear of the crown wheel and, for this purpose, spindles 33 and 34 are mounted in a frame 35, pivoted at the axis of spindle 34, and adapted to be rocked by the coned inner end 40 of an adjusting knob 3 when the latter is depressed. Rotation of the knob 3 through gearing 41-48 connecting it with the spindle 33, then traverses the slide and pinion to select the required gear ratio. As in Figs. 3 and 4 the mechanism is duplicated, each of two pinions 29 being in continuous mesh with a long pinion 30 connected to the summating differential, whilst the crown wheel 21 is engaged by both pinions and connected to the coin mechanism.

Title: Catheter
IPC: A61F2/958
Filed: 1963-04-23
Abstract: 978,102. Catheters. KENDALL CO. April 23, 1963 [May 22, 1962], No. 16009/63. Heading A5R. In a balloon catheter the balloon is inflated by a liquid which, during storage, is maintained under pressure within a reservoir but which, when required, is released from the reservoir by valve means, so as to flow into the balloon. In the form shown, the liquid 23 is held under pressure in a distensible bulb 22 by a sealing disc 27 located transversely in the tube 17. However, when this disc is turned, by suitable manipulation, so as to lie parallel to the axis of the tube, the bulb 22 collapses and the liquid flows into the balloon sac 14, to distend it. When the catheter is to be withdrawn, the balloon is collapsed by cutting or puncturing the tube 17 to allow the enclosed liquid to escape. It is alternatively possible to seal the tube 17 by doubling back the tube and tying it or by an enclosed plug with a rupturable seal.

Title: Leaching of uranium ores using alkali-metal or ammonium carbonate and bicarbonate
IPC: C22B60/02
Filed: 1953-06-11
Abstract: Uranium containing materials having a substantial proportion of the uranium in the tetravalent state are leached with a <PICT:0772867/III/1> solution containing alkali metal or ammonium carbonate in the presence of alkali metal or ammonium bicarbonate and a gas containing free oxygen and carbon dioxide, the amount of carbon dioxide being sufficient to maintain a bicarbonate concentration of at least 10 grams per litre until extraction is completed and the amount of alkali metal or ammonium carbonate and bicarbonate being sufficient to form soluble uranyl tricarbonates.  The necessary bicarbonate may be formed in situ in the case of sulphur containing ores by the reaction therewith of oxygen and sodium carbonate.  The aerating gases are normally air containing for example 1 to 2 per cent or more carbon dioxide, for example a mixture of flue gas and air.  The carbon dioxide may also be supplied when oxygen is employed as aerating gas, by recycling, when the recycled gases pick up carbon dioxide generated by bicarbonate decomposition.  The leaching may be effected at 50 to 100 DEG C. at atmospheric pressure.  As shown in the Figure, the ore is wet ground in a grinder a and fed to a filter b where the filter cake is washed by a recycle solution c, and the filter cake is then fed successively to agitators d1, d2, d3 and d4. The filter cake is diluted in agitator d1 to 50 per cent solid content by a sodium carbonate solution e and is successively agitated with the aerating gas entering the lowest agitator d4 at g, which gases pass upwardly counter-current to the descending stages of the pulp.  With a sulphide ore no carbon dioxide need be added since the aeration generates sufficient carbon dioxide in the agitator d4 by decomposition of the bicarbonate arising from the reaction between the sodium carbonate and the sulphur of the ore. With an ore not containing sulphur, the necessary carbon dioxide would be added to the agitator d4 or d3.  The contents of agitator d4 are discharged to a filter k and washed there with a recarbonated barren solution c from a scrubber j.  The leach solution is collected in tank q and the uranium therein precipitated as uranate by the addition of caustic soda from tank u.  The uranate formed is removed at r from a filter s and the barren solution is re-cycled through line y to a scrubber j where free caustic is destroyed by passing in carbon dioxide.  The recarbonated barren solution is employed as a wash on the initial filter b, on filter k and is also used to repulp the filter cake from filter k in a repulper l and to wash the pulp so formed on a filter m.  The wash filtrate from the filter m is passed to a scrubber f and from thence after treatment with carbon dioxide to the initial agitator d1 through pipe e.  Specification 716,597 is referred to.

Abstract: 924,136. Resilient mountings. SILENTBLOC Ltd. May 12, 1959 [May 20, 1958], No. 16238/58. Class 108(3). In a resilient mounting, a rubber member 13 is longer in its free state than an inner member 12. The end portions of the rubber member 13 grip the inner member 12. A plate 10 fits into a circular groove in the rubber member 13 which is of larger diameter than the diameter of the hole in the plate 10, the width of the groove being less than the thickness of the plate 10. Washers 20 are attached to the inner member 12 by bending over portions 22. The proportions of the various parts of the resilient mounting may be varied to suit different requirements. The washers 20 instead of being attached to the inner member 12 may be held against the member 12 by a bolt and nut which pass through the interior of the member 12. In a further embodiment, the inner member and the rubber member may be in two halves, 30, 31, Fig. 5, respectively. The two halves of the mounting are assembled from opposite sides of the plate like member. Before assembly the abutting edges of the rubber members project beyond the ends of the halves 30 of the inner members.
Patent GB-656837-A (GB)
Title: Method of removing weakly acidic sulfur compounds from hydrocarbon liquids
Filed: 1947-06-19
Abstract: Weakly acidic sulphur compounds such as mercaptans and thiophenols are removed from hydrocarbon liquids, particularly cracked gasolines, by a process comprising contacting the liquids with an aqueous solution containing at least 10 per cent by weight of the hydroxide of an alkali metal, an amount of alkali metal soaps of naphthenic acids substantially in excess of the amount soluble in the caustic alkali solution in the absence of a "solventizer," the amount of alkali metal soaps of naphthenic acids being sufficient materially to enhance the ability of the caustic alkali solution to extract the acidic compounds from the hydrocarbon liquids, and a sufficient amount of "solventizer" to dissolve the soap.  The "solventizer" is defined as a substance which when added to an aqueous or aqueous alcoholic solution of caustic alkali containing at least 10 per cent by weight of alkali metal hydroxide, increases the solubility of naphthenic acids or soaps thereof in the solution, and is selected from the group consisting of glycols, phenols and thiophenols.  The solventizer may be phenol or ethylene glycol, but phenols having more than six carbon atoms in the molecule, such as p- and m-xylenols, o-cresol or alpha-naphthol, and thiophenols such as thiophenol itself and meta- or orthothiocresol are preferred.  The aqueous caustic alkali solution may contain at least 10 per cent by weight of naphthenic acid soaps calculated as naphthenic acid and at least 2 per cent by weight of the solventizer.  The aqueous caustic alkali solution preferably contains approximately 10-20 per cent of free sodium hydroxide or 10-40 per cent free potassium hydroxide. The solution may contain alcohol, the proportion by volume of alcohol being less than that of the water.  Data are given for the reduction in the mercaptan sulphur content obtained by treating high-pressure thermal cracking process gasolines with 10 per cent by volume of various aqueous solutions of free caustic alkali.  In an example treatment of such a gasoline for fifteen minutes with 10 per cent by volume of a solution containing 20.5 per cent by weight of free potassium hydroxide, 8.3 of phenol and 25 of naphthenic acid followed by two 10 per cent by volume water washes reduced the mercaptan sulphur content of the gasoline from 0.0262 to 0.0009 per cent, i.e. by 97 per cent.  A repetition of the treatment followed by two water washes reduced the mercaptan sulphur content to 0.0002 per cent.  The neutralization numbers of the naphthenic acids used ranged from 230-310 mg. KOH/gm., their 10 per cent distillation points from 475-528 DEG  F. and their 90 per cent distillation points from 610 DEG  to over 622 DEG  F.

Title: Improvements relating to electromagnetic time lag devices for use with electric circuit breakers and for other analogous purposes
IPC: H01H71/44
Filed: 1929-05-28
Abstract: 330,128. Anderson, J. May 28, 1929. Electromagnets; solenoids.-A magnetic shunt in the form of a second armature or core which is interposed between the actuating core, or armature, and an electromagnet and moves independently of the armature, is used to vary the time-lag of an automatic circuit-breaker. As shown in Fig. 1, a plunger d of a sucker or dashpot type of breaker moves axially, under the action of a magnetizing force produced by an overload coil e, to operate a trip or similar device through a tappet k. The plunger d is surrounded by an iron or steel sleeve f which, when acted upon by the coil, moves axially against an adjustable spring h or weight which bears on the underside of a collar j ; downwardly-projecting arms i formed integral with the sleeve f pass freely through the collar to engage the free end of the spring. The sleeve is loaded so that it moves only on heavy overloads, the magnetic force acting on the plunger d being then diminished, thus ensuring a longer delay in operating the breaker. Fig. 4 shows the invention applied to a pivoted armature type of actuating gear, in which the armature n is encased in a spring-loaded sheath r, the armature and sheath having a common pivot. On heavy overloads the sheath moves under the section of the magnet to a position limited by a stop, where it modifies the action of the magnet on the main armature n. Specification 14812/11 is referred to.

Abstract: 315,854. Selden Co., (Assignees of Jaeger, A. 0.). July 21, 1928, [Convention date]. Aldehydes, ketones, carboxylic acids, and other oxidized organic compounds; aromatic hydrocarbons.-The catalytic oxidation of organic compounds in the vapour phase is effected in presence of a siliceous or non-siliceous base-exchange body which has been leached with dilute acid to remove a part or all of the exchangeable and non- exchangeable basic constituents, and with which a catalytically active component is either chemically combined in exchangeable or non-exchangeable form or is physically associated in the form of a diluent. The base-exchange bodies may be coated on massive carriers or admixed with diluents. When the basic components are not entirely removed the bodies may be caused to react with acid radicals to produce salt-like substances. Stabilizers, consisting of compounds of alkali or alkaline-earth metals, and stabilizer promoters, consisting of substances possessing general catalytic activity but not specific activity for the reaction in question, may be added. Details of the preparation of the base-exchange bodies are similar to those described in Specifications 281,307, 295,270 and 296,071. Examples of oxidations to which the invention is applicable are as follows :-(1) Reactions in which an intermediate oxidation product is produced, e.g. benzol, toluol, phenol, furfural, &c. to maleic, fumaric, and mesotartaric acids; cresol to salicylaldehyde and salicylic acid; toluol, xylene, pseudocumene, mesitylene, paracymene and their derivatives to the corresponding aldehydes and acids; naphthalene to naphthaquinone, phthalic anhydride, and maleic acid; phthalic anhydride to maleic and fumaric acids; anthracene to anthraquinone; phenanthrene to phenanthraquinone, diphenic acid, phthalic anhydride, and maleic acid; acenaphthene to acenaphthylene, acemaphthaquinone, bisacenaphthylidenedione, naphthaldehydic) acid, naphthalic anhydride, and hemimellitic acid; fluorene to fluorenone; eugenol and isoeugenol to vanillin and vanillic acid; methyl alcohol and methane to formaldehyde; ethyl alcohol to acetic acid; ethylene chlorhydrin to chloracetic acid.
