Title: Improvements in and relating to electric arc extinguishing apparatus
IPC: H01B3/06
Filed: 1941-10-01
Abstract: 545,868. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 1, 1941, No. 12682. Convention date, Oct. 2, 1940, [Class 38 (v)] In an arc chute in which the arc is driven into a tortuous path between interleaving ribs formed on side plates of the chute and extending in one direction transversely of. and in the other direction along, the path of movement of the arc, for example as described in Specification 541,612, close contact of the arc with the bounding walls of the path, and hence more efficient cooling thereof, is ensured by unbalancing the magnetic forces in the adjacent portions of the arc. Thus. instead of the transverse sides of the rib being parallel and the ribs of 'constant thickness and spacing, as in Specification 541,612, the above features are made varible so as to make an unsymmetrical magnetic field. Fig. 5 shows a cross-section of the chute in which the ribs are wedge-shaped so that on either side of the centre line, the distance d, is less than d 2  and hence in .the neighbourhood of the tips 10<SP>1</SP> 11<SP>1</SP>, the arc is electro-dynamically forced into contact with the spaces in the plates 10, 11 lying between the ribs. The are lies in the plane of the paper and its movement is normal thereto. The amount of zig-zagging can be progressively increased, by making the wedges project further from the side walls as the chute is traversed, Fig. 3. The ridges may alternatively each comprise a bulbous section joined to the side wall by a narrow neck, adjacent narrow necks of one side wall being separated by the bulbous portion of the other, Fig. 6 (not shown), Where ribs with parallel sides are employed, those of one side wall may be thicker than those of the other, Fig. 7 (not shown). The Specification refers also to other than parallel arrangements of the ribs, for example curvilinear or radiating from the chute, entrance. Specification 539,025 also is referred to.

Title: An improved process for the isomerization of normal paraffins
IPC: C07C9/00
Filed: 1942-09-23
Abstract: <PICT:0574939/IV/1> Normal paraffins are separated from the corresponding isoparaffins in a fractionating tower, reboiled and subjected to vapour phase isomerization in the presence of aluminium chloride on a porous carrier, and a halogen-containing promoter such as a hydrogen halide, the products being fed to the fractionating tower and, together with the feed gas, being separated into a fraction of light degradation products and promoter, fractions of isoparaffins and normal paraffins, and a fraction of heavy degradation products, all of which fractions are removed as separate streams.  The isoparaffin fraction may be passed to an alkylation zone and the product introduced into the fractionator for fractionation with the feed gas and the isomerization products.  A mixture of iso and normal paraffins, for example field butanes, gasoline or naphtha, is fed by lines 2, 3 to fractionator 5 maintained at about 150-450 DEG  F.  With a field butane, isobutane passes out by line 27, and normal butane by line 6 to a reboiler 7 and isomerizer 9 where vapour phase treatment at about 150-450 DEG F. with a throughout of about 0.2-3.5 v./v./hr., the feed being measured as liquid, at a pressure up to about 950, preferably 200-500 lbs./sq. in. is effected in the presence of about 1-20 per cent of halogen-containing promoter and a catalyst made as described in Specification 573,109 by preheating a porous carrier for 1-18 hours at 800-1200 DEG  F., admixing aluminium chloride, and heating first alone and then in a stream of inert gas at a temperature 50-100 DEG F. higher than that used in the isomerizer.  Alternatively, the chloride may be vaporized in inert gas and passed over the carrier at 250-450 DEG  F., whereby 3-20 per cent by weight of aluminium chloride is firmly absorbed.  Vapours from isomerizer 9 pass by line 10 to fractionator 5 where heavy products are separated and leave by line 24, isobutane leaves through line 27, and hydrogen chloride, hydrogen and light products pass by line 11 to a condenser whence condensate is returned by line 16, and gases passed by lines 17, 19 back to isomerizer 9, either directly or via reboiler 7.  The unreacted feed returns to the isomerizer by line 6 and reboiler 7. When combined with an alkylation, a cracked C4 fraction may be fed by line 31 to an alkylation unit 30 comprising a liquid phase reactor for mixing with sulphuric acid, a separator and a neutralizer, the hydrocarbon phase being fed by line 3 to fractionator 5.  Alkylate leaves at 24 and isobutane by line 27 from which it is returned to the alkylator.  Normal butane withdrawn through line 6 to isomerizer 9 may be isomerized only at the rate at which isobutane is removed by alkylation.

Title: Controlling & Regulating Fuel Supply to Internal Combustion Engines.
Inventor: EDWARDS ARTHUR WALLACE
IPC: F02M1/00
Filed: 1916-09-22
Abstract: 108,571. Edwards, A. W. Sept. 22, 1916. Spray carburettors.-Oils of different volatility are supplied singly, or in a mixture of any desired proportion to carburettors in which the oil is maintained at a constant level by means of a float. Petrol is led through a pipe f, Fig. 3 and a valve c, and paraffin through a pipe g and a valve d to the part of a cylinder a above a piston n which can be raised and lowered by a cable p co-operating with a spring o. The oil mixture passes down a passage m to a pipe b leading to the float chamber, The chamber above the valve c communicates with the cylinder a below the piston n by means of a passage q. To start the engine, using petrol, the piston n is lowered and the oil mixture thus sucked back into the upper part of the cylinder a. The piston n then depresses a valve j and allows petrol to flow down the passage into the lower part of the cylinder a and through the valve j to the float chamber, where it is used for starting. When the engine is running, the piston is again raised and the fuel mixture above it is forced partly into the float chamber down the pipe m, and partly up the pipe g. The further raising of the piston lifts the valves c, d off their seating and allows the petrol and paraffin to flow together to the float chamber. Oblique slots or surfaces on the extensions i of the valves c, a, or tapering stems, are so arranged that the increase of the flow through one of the valves c, d coincides with a decrease of flow through the other. Fig. 6 shows an arrangement where either petrol alone or paraffin alone is used. For starting on petrol, the piston n is lowered and the float chamber emptied. The piston depresses the valve c and allows petrol to flow from the pipe f through the valve c to the float chamber. The raising of the piston cuts off the petrol supply and lifting the valve d puts the paraffin pipe g into communication with the float chamber through the upper part of the cylinder a and the passage m.
