Title: Improvements in thermostats
IPC: G05D23/12
Filed: 1955-09-08
Abstract: 779,593. Temperature-responsive actuating-elements. GENERAL MOTORS CORPORATION. Sept. 8, 1955 [Sept. 27, 1954], No. 25733/55. Class 64(2) [Also in Group XXIX] In a bellows 56 containing a thermally expansible liquid up to a level X, a cupmember 62 is secured, e.g. as by solder 64, and has an opening 68 which forms a restricted passage for the flow of liquid to dampen the movement of the bellows as it deforms with change of temperature.

Title: Process for the demineralisation of water by ion exchange
IPC: B01J49/40
Filed: 1973-05-30
Abstract: 1428207 Demineralization of water by ion exchange ICI AUSTRALIA Ltd and COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 30 May 1973 [30 May 1972] 25751/73 Heading C1C An improvement in the known process for demineralizing water containing a mixture of mono and divalent cations by a bed of ion exchange resins containing mixed weak acid and weak base groups consists of the adsorption temperature being at ambient or supply temperature and the temperature of elution being above 95‹ C. and below the temperature at which the resin either decomposes or deforms. The bed is regenerated by eluting it with water or a saline solution at a temperature exceeding that employed during adsorption; the said weak acid having a titration curve at the temperature of the adsorption stage such that some portion of it falls within the area defined by the titration curves of the weak base at the temperatures of the adsorption and elution stages respectively and said weak base having a titration curve with an almost steady pH value over a major portion of the titration curve, which curve is displaced to a more acid position by elevation of the temperature.
Patent GB-783601-A (GB)
Title: Improvements in or relating to the recovery of plutonium from solutions containing it
IPC: G21C19/46
Filed: 1947-09-23
Abstract: Plutonium is removed from solutions containing it in a lower state of oxidation than the hexavalent by treating the solution with a fluoride which has a water solubility at 15 DEG  C. of 1 gramme or less in 10 litres of water and which is able to absorb the plutonium leaving other ions, for example uranium in solution. Fluorides of calcium, strontium, lanthanum and other rare earth metals are preferred.  The process is particularly useful in the treatment of neutron irradiated metallic uranium which may be dissolved in an acid, preferably nitric to form a 30-50 per cent uranyl nitrate solution.  Such a solution may be treated with an oxidizing agent such as potassium dichromate or sodium persulphate in the presence of silver ions to oxidize the plutonium to the hexavalent state.  After heating to about 80 DEG  C. to complete the oxidation the solution may be cooled and then passed through a fluoride as above defined, in granular form placed in a column.  Absorbable fission products are removed leaving the plutonium in solution.  In order to prevent the uranyl nitrate solution having a solvent action on the fluoride it is preferable to add salts of hydrofluoric acid to the solution, for example calcium fluoride or lanthanum fluoride until the uranium solution is saturated, thereby preventing any dissolution of the fluoride absorption agent.  After treatment of the solution with the fluoride the latter may be washed with a dilute acid preferably 1 to 2 N nitric acid and the washings combined with the main solution. The solution is now reduced with for example sulphurous acid to convert the plutonium in solution to the quadravalent state and the reduced solution is brought into contact with a separate mass of calcium, strontium or rare earth fluoride to absorb the plutonium, leaving uranium and the other non-absorbable fission products in solution.  The fluoride may be washed with dilute acid as before and the plutonium may be finally removed from the fluoride by treatment with ammonium oxalate or ammonium carbonate or bicarbonate, such solutions dissolving the plutonium probably as a complex fluoroxalate or fluorcarbonate.

Title: Improvements in electrical condensers
IPC: H01G5/38
Filed: 1924-10-31
Abstract: 248,031. Courser P. R., and Dubilier Condenser Co. (1925), Ltd. Oct. 31, 1924. Condensers of the type which are continuously variable in capacity from a minimum to a maximum have the variation effected by a simultaneous change both in the area of overlap of the vanes or plates and in their effective distance of separation. The two vanes 1, 2 are, as shown,. arc-shaped flat plates the plane of which is inclined to the axis of the spindle 6, and are enclosed in a circular cylindrical casing. Rotation of the spindle effects simultaneous variation in both the distance between the centres of area of the plates and the area of overlap. When the spindle has been rotated 180‹ from the position shown in Fig. 2, the capacity will be very small, and the law of the condenser may be varied by varying the angle betwen the plane of the plates and the spindle from the 45‹ position shown, 60‹ being a suitable angle although slightly augmenting the minimum. The shape of the plates may also be modified to alter the law, and, if more than one pair of plates is used, their angles with respect to the spindle axis may differ from one another.

Filed: 1928-09-11
Abstract: 304,273. Ohler, E., and Ohler, K., (trading as Ohler, J. F.). Jan. 18, 1928, [Convention date]. Saws, sharpening.-In a machine for grinding the teeth of saws of the type having high cutting teeth and lower clearing teeth arranged alternately, the grinding-wheel is actuated so that it performs the required deep and shallow operative strokes alternately, and the saw is thus completely sharpened without re-setting. The machine frame 1 carries an angularly adjustable head 2 through which passes a central actuating shaft 3 carrying an eccentric 11 engaging a block 12 working in a member 13 over which engages a forked member 14. The member 14 carries a pin 15 engaging in a block 20 which is horizontally adjustable by a screw 16 in a slotted plate 17 which is thus vertically reciprocated. A housing 10 carrying the grinding-wheel 19 is adjustable vertically on this plate by means of a screw 18. In order to enable the grinding-wheel to grind high and low teeth alternately, the shaft 3 carries a pinion 4 engaging a pinion 5 which drives through a clutch a shaft 8 carrying an eccentric 21 engaging a slot in the oscillating member 13. This horizontally reciprocates the member 13 which has inclined top and bottom edges so that a rising and falling movement is imparted to the slide 14 and hence to the grinding-wheel, the movement being so timed that on its operative strokes the grinding-wheel shapes the required alternating high and low teeth on the work.

Abstract: In bread manufacture, substances rich in water-soluble b  vitamins are substituted for equal weights of the sugars usually employed. The substances are obtained from such by-products as rice polishings, wheat bran and the germs of cereals, for example, wheat and maize germs, by first freeing them from their vegetable fat, some of the colouring-matter, and the bitter and acrid substances, by treating them with benzol, carbon tetrachloride, or the like.  The water-soluble b  vitamins may be extracted, after the fat separation, by agitating the germ with water or alcohol for three hours at 140 DEG  F. and then evaporating.ALSO:By-products such as rice polishings, wheat and maize germs, are freed from their vegetable fat, some of the colouring-matter, and the bitter and acrid substances, by treating them with benzol, carbon tetrachloride, or the like.  Crushed or ground roasted peanuts may be added and likewise freed from oil.

[Also in Group XXXVI] A flexible conduit comprising a plurality of braided wire tubes 14-17 lined and impregnated with flexible material is made by assembling the tubes to form a mulitply hose, filling the hose and the spaces in and between the walls of the tubes with a viscous compound, suspending the hose with its longitudinal axis vertical until excess compound flows out to leave a central passage, and baking the hose to convert the compound to a non-flowable solid. After assembling the tubes they may be soldered together at each end and inserted in an annular ferrule 18 of channel-shaped cross-section which is then secured in an end-fitting 11. A primer may then be applied to the internal surface of the hose and the assembly be immersed in the impregnating material while the pressure is reduced to permit the material to permeate the tubes, when the pressure is restored. Excess compound may be removed from selected surfaces of the hose before baking, or after the baking has been started but before it is completed. The impregnating compound may be a fluid dispersion of polyvinyl chloride which is reduced by baking to an elastomeric vinyl compound, or the compound may comprise a silicone rubber.
