Title: A process for the production of alcohols
IPC: C07C29/82
Filed: 1932-09-30
Abstract: In the production of alcohols from olefines and sulphuric acid, the alcohol-water mixture obtained is completely or substantially dried for instance by copper sulphate, lime or calcium chloride or by azeotropic distillation with toluene, xylene, ethylene chloride, benzine fractions or the like, before the final distillation, which is then effective for separating the alcohol from unpleasant-smelling polymers.  In examples (1) the crude aqueous isopropyl alcohol is concentrated to 88 per cent strength by azeotropic distillation, dried with anhydrous copper sulphate and fractionally distilled; it is stated that if potash were used for the drying, the final distillation would not remove the polymers; (2) the same crude isopropyl alcohol is dehydrated by distillation with toluene with return of the toluene layer of the condensate, and is then fractionally distilled.  Specification 334,228, [Class 2 (iii), Dyes &c.], is referred to.ALSO:In the production of alcohols from olefines and sulphuric acid, the alcohol-water mixture obtained is completely or substantially dried for instance by copper sulphate, lime or calcium chloride or by azeotropic distillation with toluene, xylene, ethylene chloride, benzine fractions or the like, before the final distillation, which is then effective for separating the alcohol from unpleasant-smelling polymers.

Filed: 1959-08-10
Abstract: 891,659. Batteries. GEISSBAUER, K. Aug. 10, 1959, No. 27311/59. Class 53. The positive plate of a lead-acid battery comprises a lead grid consisting of a frame 1 and vertical or horizontal or (as shown) diagonal bars 5, to one or each side of which is applied a microporous synthetic resin grid 2 having hexagonal openings containing the active paste 7 and sealed by a separator 9 of glass fibre or fabric. To prevent corrosion at points 10 where the bars 5 are cast to the frame and at points 11 where they contact the grid 2, the latter is compressed at these positions to be no longer microporous. Circular (or rectangular, Figs. 5 and 6, not shown) lugs 6 serve to increase the contact surface between the paste 7 and bars 5. The negative plate is similarly constructed with the resin grid having circular openings covered by flat or corrugated microporous separators, Figs. 7 ... 12 (not shown).

Filed: 1970-06-05
Abstract: 1319361 Liquefied gas burners RONSON CORP 5 June 1970 [23 June 1969] 27415/70 Heading F4T A portable cooking device comprises a reservoir 10, 14, for liquefied hydrocarbon fuel gas, connected by a passageway to a fuel burner mounted on the reservoir, the passageway including a valve comprising a tapered needle 29 movable in a Venturi nozzle 26 to control the flow of gaseous fuel into a mixing chamber 20; air flows to the chamber via an inlet 43, the size of this inlet and also the gas valve being controlled simultaneously to increase or decrease the flow of both air and gas to the mixing chamber 20 so as to maintain a stable flame. The tapered needle 29 is loosely mounted at one end of a shaft 28, the other end of which is secured in a knob 34. Integral with the shaft is a threaded portion 31, so that rotation of the knob 34 causes the shaft to move to the right, opening the valve. Simultaneously a barrel 32, also integral with the shaft bears on ribs 37 provided on a handle 34, moving the handle and thus widening the air inlet 43. The air/gas mixture flows from the chamber 20 via an outlet bore 21, to the burner which comprises a burner head 52 having openings 57. The burner head seats in an insulator 48 mounted in a reflector 44, the reflector fitting into a ceramic insulator 46 which is pressed into a socket in the reservoir. The insulator 46 prevents heat flowing from the burner to the reservoir.

Abstract: 1,012,129. Electrostatic spray producers. HURSANT DEVELOPMENTS Ltd. Nov. 13, 1961 [Aug. 11, 1960], No. 27825/60. Heading B2F. An electrostatic spraying apparatus comprises a rotatable electrically non-conducting cup, e.g. nylon, on a conductive shaft 5 and spider 4 driven by a pneumatic motor 23, and a nozzle 21 which directs coating material, supplied under pressure through an inlet 20 under the control of a needle valve 18, on to a disc which is fixed to the shaft 5. The material forms a film on the disc, travels toward the edge thereof due to the disc's rotation and leaves the disc to form a film on the interior surface of the cup which is tapered. The coating material is subsequently flung off a sharp edge 28 of the cup in atomized form. A high voltage source (100 kV) is connected, via a coaxial cable (not shown) and limiting resistors (not shown) in a tube 10, to a terminal 16 which is electrically connected through a ball race 12 to a conductive shaft 5 and thence through the spider (and the disc if it is conductive) to the film which assumes the potential of the spider. The atomized particles travel toward an article to be coated, which is at earth potential, under the influence of the electrostatic field which may also assist the atomization. The drive shaft portion 14 is electrically non-conductive.

Title: Improvements in starters for engines
IPC: F02N15/06
Filed: 1926-11-06
Abstract: 261,032. Jackson, M. B. Nov. 7, 1925, [Convention date]. Turning-gear.-In an electric starter comprising a pinion 4 movable axially on the screwthreaded shaft 3 of the starting motor into engagement with an engine gear 5, the first part of the axial movement is effected by means of a finger 9 pivoted on a pedal-actuated bell-crank lever 6. The finger' 9 engages a flange 4a on the pinion 4, and the arm 9a of the finger is connected to the lever 6 by a spring 10, so that, if the teeth of the pinion 4 clash with those of the gear 5, the finger will rotate the pinion sufficiently to cause meshing of the two gears. The end 9b of the finger 9 may have a sharp edge for engagement with the flange 4a, a projection 9c on the finger being engaged by the flange, on the return of the pinion, in order to prevent damage to the sharp edge. The axial movement of the pinion 4 is limited by a collar 14 and by a washer 15 secured by a nut 20. An arm 6b on the lever 6 switches on the starting motor when the pinion comes into engagement with the gear, the axial movement then being completed automatically by the screw-thread 3, which also effects disengagement when the engine starts. If the engine fails to start or turns backwards, damage is prevented by the spring 10. The pinion is normally retained in the disengaged position by a spring-pressed ball 16 in the shaft 3. When the pinion is in the fully meshed position, the ball 16 serves to prevent its disengagement by a slight sudden impulse from the engine.

Title: Improvements in or relating to extraction of uranium from ore
Inventor: NAPIER ELIZABETH
IPC: C22B60/02
Filed: 1951-12-01
Abstract: Uranium is extracted from its ores by leaching with an aqueous alkali metal carbonate solution containing a dissolved persulphate salt whereby the uranium passes into solution and a uranium-containing concentrate is recovered therefrom, preferably by precipitation as a diurnate with an alkali metal hydroxide.  Alternatively the uranium - containing solution may be contacted with an anion exchange resin to absorb the uranium which is then recovered by elution with an aqueous salt solution.  The alkali metal carbonate employed for leaching is preferably sodium carbonate the solution suitably containing 5 to 20 per cent thereof.  Sodium and ammonium per-sulphates are preferred oxidizing agents.  According to an example an uranium ore was mixed with a solution containing 10 per cent by weight of sodium carbonate and 4 per cent of sodium persulphate and the resulting pulp was heated to 60 DEG C. with gentle agitation.  The extract was treated with sodium hydroxide to precipitate the uranium as sodium diuranate. The filtrate was then evaporated and further sodium persulphate was added thereto and the solution treated with carbon dioxide to reduce the pH to 11.8 after which it was employed to treat further ore. Alternatively the uranium may be recovered from solution by an anion exchanger in which case the sodium carbonate and bicarbonate concentrations are preferably adjusted to less than <FORM:0774371/III/1> and <FORM:0774371/III/2> respectively.  The anion exchanger may be in chloride sulphate or carbonate form and the absorbed uranium may be eluted with a solution of sodium chloride, bicarbonate or sulphate or ammonium carbonate or nitrate.
