Patent GB-160257-A (GB)
Abstract: 160,257. Withers, J. S., (Renault, L.). Dec. 15,1919. Protective arrangements for lamps in vehicle lighting installations of the kind comprising an axle driven dynamo and a storage battery. The invention consists in automatically inserting in parallel with the lamps to be protected an auxiliary battery or alkaline accumulator. One arrangement shown in Fig. 1 is composed of a dynamo a, a storage battery b, and lamps c, protected by an electromagnet d which, when the dynamo voltage becomes too great attracts an armature e, thus unlatching a normally open switch g and allowing it to be closed by a spring h. This puts an auxiliary alkaline battery m in parallel with the lamps. A contact on thepivoted armature may replace the latch and switch. An. indicating lamp may be placed in the shunt containing the auxiliary battery. The auxiliary battery may be used for engine ignition purposes.

Abstract: 582,679. Telegraph transmitters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., STYLES, L. C., and BROOKER, V. D. Aug. 28, 1944, No. 16312. [Class 40 (iii)] An automatic transmitter using morse or like perforated tape comprises two photo-electric cells 12, 13 which are exposed in succession through apertures in a revolving cylinder 6 and through holes in the tape to lamps 16, 17 for registering marks and spaces respectively. The tape travels at right angles to the plane of Fig. 2 upon a platform 23, which is slotted at 21 for the passage of light, and under a bridge 18. A slotted hollow cylinder 6, or a solid apertured cylinder, is geared to the tape-feed mechanism, Figs. 1 and 3 (not shown), and co-operates with two slots 19, 20, which are staggered in the direction of feed of the tape, so that the slot 19 is uncovered by a marking hole at the beginning of a dot or dash and the slot 20 is uncovered by the corresponding spacing hole at the end of the dot or dash. Thus, to register a mark, the slot 19, a marking hole in the tape and two opposite slots in the cylinder 6 have to be in alignment; the tape then moves on so that, in the case of a dot, the slot 20, a spacing hole and the slots in the cylinder 6 come into alignment to register a space.

Abstract: 515,691. Luminescent powder. PEARCE SIGNS, Ltd., and PEARCE, J. H. G. June 1, 1938, No. 16413. [Class 39 (i)] [Also in Groups XV and III] Deposits of luminescent material for use in electric discharge devices, more particularly luminous tubing, are produced by applying to the surface upon which the deposit is to be made a liquid consisting of or containing an ester of silicic acid which may be readily converted into a non-volatile component consisting essentially of silica and a volatile component, applying powdered luminescent material to the layer of liquid, converting the liquid into the solid and volatile components, and removing the latter. The liquid is preferably ethyl silicate and is applied in a thin layer by pouring through the tube and afterwards passing a sponge through to remove the surplus. The luminous powder may include tungstates and silicates and may be applied in any suitable manner or it may be mixed beforehand with the liquid and the two applied together. The silicon ester is then treated with water by passing steam through the tube to produce hydrated silica and alcohol. The volatile component of the hydrolyzed ester is then driven off by heat which can take place during the evacuation of the tube. Specification 510,433, [Group XV] is referred to. Reference has been directed by the Comptroller to Specification 494,105, [Group XV].

Title: Improvements in the production of vanadium pentoxide
IPC: C01G31/02
Filed: 1958-05-23
Abstract: Vanadium pentoxide is produced from materials containing oxidic compounds of vanadium and alkali metal values by forming an ammoniated aqueous solution containing vanadium which is, or has to be converted to the pentavalent state, adjusting the ammonium to alkali metal ion ratio to at least 2.1, heating the aqueous solution between 75 and 90 DEG C., adjusting the pH to 2.1 with an acid thereby forming water soluble salts of alkali metals and precipitating an ammonium polyvanadate.  The polyvanadate is then heated under oxidizing conditions at 190 to 400 DEG C. forming vanadium pentoxide which is thereafter fused at 670 to 950 DEG C. The initial oxidic compound of vanadium may be an alkali metal vanadate, a hydrous vanadium oxide or a mixture thereof and normally results from the salt roasting of vanadium containing ores such as carnotite. In an illustrated sequence an alkali metal hexavanadate is dissolved in ammonium hydroxide to form a solution containing to 1 to 5% V2O5 having a pH of 8. Such solution is then treated with hydrogen peroxide or potassium permanganate, to oxidize the vanadium to the pentavalent state. The resulting metavanadate solution heated to 80 DEG C., is treated with ammonia until the ammonium ion/alkali metal ion ratio is at least 2:1 and sulphuric acid then added to bring the pH to 2:1 and the mixture digested at 75 DEG C.  Ammonium hexavanadate precipitated leaving a solution of alkali metal sulphates.  The polyvanadate precipitate was washed and dried at 180 DEG C., re-dissolved in concentrated ammonium hydroxide and reprecipitated by the addition of sulphuric acid; the purified product was fused at 400 DEG C. and thereafter heated to 700 DEG C. to form a molten vanadium pentoxide product, which was solidified in the form of flakes.
