A burner for shaft fornaces comprises a nozzle g having located therein a needle i urged by a spring k against the nozzle orifice h to close it, and a piston pump a which supplies fuel oil through a pipe e into a chamber f surrounding the orifice h so that as the piston descends there is a build up of pressure in chamber f which overcomes the resistance of spring k and pushes the needle i away from orifice h through which the fuel is atomized. As the piston ascends, the pressure in chamber f drops and the needle i returns to close orifice h. The piston is caused to reciprocate by a crank c and oil is drawn in through a pipe d containing a non- return valve, not shown.

Filed: 1948-02-26
Abstract: 649,922. Boundary layer control. CUSTER, W. R. Feb. 26, 1948, No. 5765. Convention date, Aug. 28, 1942. [Class 4] An aeroplane wing comprises an inner portion in the shape of an upwardly opening channel extending in the direction of flight from the leading edge of the trailing edge of the wing, an outer portion, a slot in the upper surface of the wing and a conduit leading from the slot to the inner surface of the channel portion, whereby the boundary layer associated with the outer portion will tend to be drawn into the channel whenever a reduction in pressure is induced at the inner surface of the channel portion. In the embodiment shown a channel portion 6 of a wing is separated from a contiguous portion 5 by a fin 9. Air from the boundary layer on the portion 5 is collected in the slot 7 and conveyed by the conduit 8 to the surface of the portion 6. The fin 9 not only prevents spill over of air from portion 5 to portion 6 but also baffles the air delivered from conduit 8 against return. In a modification (Fig. 4, not shown), the fin 9 is omitted and the conduit 8 is extended to discharge in the neighbourhood of the bottom of the channel.

Title: Improved manufacture of titanium compounds
IPC: C22B34/12
Filed: 1949-03-03
Abstract: An alkali metal titanate product is obtained by reacting at 500 DEG -1,000 DEG C. and under oxidizing conditions, e.g. in air, a titanium ore or concentrate containing at least 60 and up to 90 per cent. or more TiO2 e.g. rutile, with an alkali metal compound in quantity equal to 2 atoms alkali metal per 5 atoms titanium, plus the amount required to convert into water-soluble alkali metal oxidation products substantially the whole of the elements present which are so convertible, especially chromium and vanadium, and subsequently washing the water-soluble substances from the reaction mixture.  The washing water may contain a wetting agent or a substance for adjusting the pH value.  Sodium or potassium sulphate or carbonate are suitably used as the alkali metal compound.  The reaction mixture may also contain oxide, hydroxide, carbonate or sulphate of calcium or magnesium to enhance its free-flowing quality.  The titanate may be used as a pigment, or reacted with sulphuric acid, or compound liberating it, at 100 DEG -500 DEG C.  The sulphation product is dissolved in water or dilute sulphuric acid.  Two examples disclosing hydrolysis of the solution are furnished, using a nucleating solution produced by diluting the original solution, heating the diluted solution to 65 DEG C. and adding caustic soda to give a pH value of 3.5.  The nucleated solution is boiled for specified periods, and then slowly diluted with water whilst boiling is continued.  In an example, the filtered and washed hydrolysate is mixed with 0.3 per cent. potassium carbonate and calcined at 930 DEG C to anatase; in the other, it is mixed with 0.2 per cent. magnesia, and 0.3 per cent. sodium carbonate and calcined at 930 DEG C. to rutile.  Specification 408,125 is referred to.

Abstract: 538,458. Aerials. MULLARD RADIO VALVE CO., Ltd. April 1, 1940, No. 5871. Convention date, April 4, 1939. [Class 40 (v)] To reduce the effect of electric fields a loop antenna consists of two series-connected groups having different numbers of turns in which the junction of the groups is earthed and the ratio of the numbers of turns in each group and the place of each turn is chosen so that the influence of electric fields on one of the groups is compensated by the other group. Fig. 2 shows a cross-section through the turns of. a loop aerial in which turns 12...18 are located in equipotential surfaces (indicated by circles) of the central turn 11, thus greatly reducing the capacity of the loop. Turn 16 is earthed and so turns 17, 18 serve to compensate the effect of electric fields on turns 11 ... 15. The aerial is arranged in an insulating casing 10.

Title: Polymerization of ethylene
IPC: C08F10/00
Filed: 1966-02-10
Abstract: Ethylene is polymerized by a method comprising providing two streams of ethylene at pressures above 15,000 p.s.i.g., cooling the first stream to below 60 DEG  C. and mixing a catalyst therewith, heating the second stream to at least 120 DEG  C., continuously recombining said streams in a polymerization zone by flowing the first coaxially within the second while radially injecting the first into the second at a multiplicity of points along said polymerization zone whereby uniform temperature and catalyst concentration are maintained in the zone during polymerization of the ethylene, and removing ethylene containing polyethylene from the polymerization zone.  A single ethylene stream may be compressed and divided or two separate streams may be compressed, the first being a recycle stream which may contain 70 to 90% of the ethylene, and the second a stream of fresh ethylene. Catalyst such as lauroyl peroxide may also be added to the second stream. Injection may be effected by maintaining a pressure differential between the streams.  The catalyst may be an organic peroxide, azo compound or oximine, and may be added as a solution in a hydrocarbon solvent.  Apparatus suitable for carrying out the method of the invention is described and illustrated, and examples describe the polymerization of ethylene using as catalysts benzene solutions of mixture of t. butyl perbenzoate with dicumyl peroxide or t. butyl peracetate, and a telogen such as butane.
