Title: Mineral fibreboard and method of making the same
IPC: D21H17/28
Filed: 1960-09-14
Abstract: 934,638. Mineral fibreboard; pulping fibres. WOOD CONVERSION CO. Sept. 14, 1960 [Feb. 1, 1960], No. 31677/60. Drawings to Specification. Class 96. Mineral fibreboard comprises 77 to 100 parts of felted fibres bound by starch gelled and dried in situ from starch grains in a quantity of 4 to 20 parts. Of the felted fibres, 77 to 90 parts are mineral fibres and 0 to 10 parts are substantially unhydrated cellulosic fibres. Of the mineral fibres, at least 75 parts are artificial fibres and 2 to 15 parts are asbestos fibres. The artificial fibres may be of glass wool, slag wool, rock wool or limestone wool, the cellulosic fibres, if any, of cotton, wood fibre, or paper-making fibres. The asbestos fibres act as a thickening agent, and make the wet mat handleable. Non-fibrous thickening agents may also be present, and may be bentonite, water-soluble gums, proteins, such as gelatine or soy protein, carboxymethylcellulose, or gelatinized normal or chemically treated starch. The board may be made by forming a mat from an aqueous slurry in which the starch is in grain form, heating the mat to a temperature at which the starch grains gelatinize, and finally drying. The product is fireretardant, and may be produced with a density suitable for use as an acoustic tile. A wax-size may also be used in the finish to make the board water-resistant. If the artificial mineral fibres are in the form of nodules, i.e. ball-like felted clumps, they may be defibred, at least in part, opened up and reduced in size by agitation in water which contains the starch grains and the thickening agent, to form a slurry which can later be diluted to a consistency suitable for supply to the board-making machine. This treatment also moves starch grains into any nodules which may remain.

Patent GB-907465-A (GB)
Title: Improvements in or relating to the recovery of molybdenum and/or vanadium values
IPC: C01G39/00
Filed: 1960-09-15
Abstract: Vanadium and/or molybdenum values are recovered by treating an aqueous solution containing one or more of such values with a waterimmiscible quaternary ammonium extractant phase comprising a compound (generally 5 to 15 volume per cent) of the formula <FORM:0907465/III/1> where R is an alkyl group having 1 to 4 carbon atoms, the R1 groups are aliphatic groups containing 8 to 22 carbon atoms either alike or different and which may be straight or branched chain, saturated or unsaturated, and X is an anion, e.g. sulphate or chloride.  A conditioner (2 to 10 volume per cent), e.g. a long chain fatty alcohol, e.g. capryl alcohol, isodecanol, tridecyl alcohol or 2-ethyl hexanol and a diluent such as kerosene may also be present. The metal values are preferentially extracted into the organic phase which after separation from the aqueous phase can be stripped using solutions of salts, e.g. nitrates or chlorides of alkali metals, alkaline earth metals or ammonia, resulting in a purified, concentrated aqueous molybdate or vanadate solution.  The stripping solution may also contain an alkali such as sodium or ammonium hydroxide.  Strongly alkaline solutions (e.g. 5 to 20% by weight NaOH) can also be used alone to strip the metals from the organic phase.  The liquid-liquid extraction process can be carried out in a continuous countercurrent mixer-settler unit.  The examples given illustrate the recovery of vanadium and/or molybdenum from aqueous solutions, this recovery being effected in the presence of carbonate, thionate and phosphate ions.  Example 1 illustrates the recovery of molybdate from a solution obtained in the acid leaching of uranium ores.  The uranium pregnant acid solution is contacted with an amine salt or an organophosphate and the uranium and molybdenum pass into the organic phase which is then separated from the aqueous solution. After stripping uranium with sodium chloride, part of the organic phase is bled off through a scrubbing operation and the molybdenum collects in the aqueous alkaline scrub solution, which after treatment with sulphur dioxide to bring the pH to between 4 and 4,5, is treated with the quaternary ammonium extractant phase consisting of an alkyl monomethyl ammonium chloride, isodecanol and kerosene.  A sodium chloride-sodium carbonate stripping solution is used.  Calcium molybdate is precipitated at 25 DEG C. by a two-stage process, calcium chloride first being added to precipitate calcium sulphite which is removed and then more calcium chloride is added to precipitate calcium molybdate.  In Example 2 molybdenum is recovered from a solution obtained in the alkaline leaching of uranium ores.

Title: Improvements in radio receiving circuits
IPC: H04B1/10
Filed: 1935-11-19
Abstract: 465,282. Wireless receiving systems. PLESSEY CO., Ltd., BAILEY, C. E. G., and BAILLIE, G. Nov. 19, 1935, No. 32039. [Class 40 (v)] For minimizing the effect of interference in a radio receiver the signal is periodically applied to and periodically withheld from a resonant circuit feeding the later stages of the receiver and which is lightly damped at least during the latter periods. The time during which the signal. is applied to the circuit is preferably a small fraction, e.g. one hundredth of the total period. As shown, an I.F. amplifiying valve V1 is normally biassed to cut-off by a grid bias derived from the cathode resistance R4, signals from the input circuit L2, L3, C3 being prevented from energizing the output anode circuit L1, C1, the damping of which can be adjusted by a variable feed back coil L6 energized from a later stage of the receiver. A local oscillator V2 provides a " peaky " wave form which is applied. to the control grid of valve V1 from the resistance R1 and renders it operative for a short fraction of each cycle. The damping of the circuit L1, C1 may be made negative during the intervals when no signals are applied thereto, the oscillations which build up therein being quenched periodically. This quenching may be effected from the oscillator V2. The circuits preceding the circuit L1, C1 should preferably be damped to prevent the persistence of interfering impulses. When the receiver is used on aircraft the control of the signal access to the circuit L1, C1 may be effected by mechanical or electrical means operating in timed relationship with the ignition system of the engine.
