Title: Fuel Injection Nozzles for Internal Combustion Engines.
IPC: F02M69/04
Filed: 1965-09-08
Abstract: 1,155,273. Spray carburetters. PETROL INJECTION Ltd. and H. E. JACKSON. Sept. 5, 1966 [Sept. 8, 1965] , No. 38395/65. Heading F1B. A fuel injector situated in an intake manifold comprises a fuel tube 8 disposed in an outer jacket 3 vented to atmosphere at 15, the fuel escaping through an orifice 10 aligned with a converging orifice 6 in the jacket 3. The exit aperture of orifice 6 is larger than orifice 10. The orifice 6 is of such size that the pressure inside jacket 3 remains substantially atmospheric despite high vacuum conditions in the intake manifold. The fuel enters at 11 and flows to tube 8 through filter 13. A fine wire 17 in the tube 8 forms a restriction to the fuel flow which may be adjusted for individual injectors by varying the length of the wire.

Abstract: 1,188,326. Transformers. HIRST ELECTRIC INDUSTRIES Ltd. 12 July, 1968 [21 Aug., 1967], No. 38465/67. Heading H1T. A transformer, e.g. for electric arc welding, comprises primary 23 and secondary 24 windings on one leg 12 of a magnetic core 11, the secondary winding also embracing a movable core member 19 which abuts, in its lowered position, extended portions 16, 17 of the upper and lower yokes 14, 15 and which is movable to vary the air gap between itself and one of the yoke extensions (17). Member 18 and, correspondingly, the end of extension 16 are slightly tapered so that contact between the two is broken as soon as member 18 is raised slightly from its lowered position. The core is laminated and is constructed in two parts 11a 11b, which meet in V-shaped interfaces 21, 22 and are rigidly clamped in a frame. The yokes and the leg 13 are wider than leg 12 and member 18. The lower yoke extension 17 has a portion 26 of reduced width carrying a first bias coil 27 connected to either the primary or secondary winding to oppose the leakage flux at no load, and a second bias coil 28 connected in series with the secondary and suitably comprising a single turn to oppose the flux produced by coil 27 under load. For a three-phase transformer, Figs. 2, 3 (not shown), three transformers similar to Fig. 1 are disposed at 120 degrees to each other so as to form magnetically continuous starshaped yokes, legs 13 being omitted if desired. Means are provided to raise or lower all three movable members 18 together. Rectifier units (29) may be disposed within the outer periphery of the structure and a fan for forced ventilation may be mounted in the space (30) above the upper yoke.

In a method of unwinding a strand 12 continuously from successive helically wound packages 7, 5 the strand is pulled downwardly from the interior of a vertically-disposed helically wound package 7 the other end 25 of the package, which lies on the outside thereof, being attached to the inner end 23 of an adjacent, similar but horizontally-disposed package 5; when the package 7 is completely unwound the package 5 is placed in the vertical position and a further package installed in the horizontal position and its inner end is attached to the outer end of the package 7. A moulded plastic base 3 is provided with suitable recesses 6, 4 to support the packages in the respective vertical and horizontal positions and with grommets 8,10 to guide the strand 12 to an adjustable tensioning device 11 mounted in a further recess 9 in the base 3. The tensioning device comprises two pairs of dished plates 17 supported on rods 15,16 mounted on a rotatable plate 13. Movement of the plate 13 adjusts the amount of contact between the strand 12 and the rods 15,16 and the plates 17. The strand which as described is a multifilamentary glass strand passes through a further grommet 18 to a common guide eyelet for a plurality of such strands (Fig. 1 not shown) and thus to a tape making machine (not shown). Breakage or a strand can be rectified by placing adhesive on the broken end and attaching it thereby to an adjacent unbroken strand.

Filed: 1960-11-11
Abstract: Materials such as filaments, fabrics, leather, paper or foils of natural or synthetic origin are treated with silicones and also with reaction products of epoxide resins and di- or polyamines. The reaction products are used as solutions or emulsions in water or organic solvents, and may be in the form of salts of volatile organic acids.  The silicones may be used as such or as solutions or emulsions in water or organic solvents.  The material may be treated with the reaction product, and then with the silicone, or with the two simultaneously.  There may also be used with the reaction products substances which show, in aqueous solution, a practically neutral reaction at ordinary temperature, but form alkaline products at high temperatures, e.g. the salts of strong bases with volatile acids (examples given in the Specification). The treated material may be dried and heat-treated.  Known catalysts for hardening the silicones may be employed, e.g. compounds of zinc or titanium. Specifications 680,265, 854,952 and 933,729 are referred to.
