Title: Improvements in or relating to liquid fuel burners
Inventor: CAMPBELL IAIN BROWN
IPC: F23D11/24
Filed: 1958-03-13
Abstract: 918,411. Liquid fuel atomizers. BABCOCK & WILCOX Ltd. March 13, 1959 [March 13, 1958], No. 8074/58. Class 75 (1). The sprayer plate 32 of a fuel atomizer has a conical outlet 61 extending outwardly from the discharge orifice 46 and terminating in a sharp annular edge 62. The conical outlet 61 has a vertical angle between 15 degrees less than and 10 degrees greater than the spray angle at full load from a sprayer plate not provided with the conical outlet. The sharp edge 62 is defined by the outlet 61 and a further conical surface forming part of a V-groove on the front face of the sprayer plate. In another embodiment the front face has two V-grooves. The sprayer plate 32, a distance plate 31 and a flange 29 on a distributer head 27 are clamped against a shoulder on an outer barrel 13 by a cap nut 33. The rear part 26 of the distributer head 27 surrounds an inner barrel 14. Fuel passes along the space 45 between the inner and outer barrels 13, 14, through apertures 44, 43 in the flange 29 and distance-plate 31 to six squaresection slots 42 channelled in the rear face of the sprayer plate and leading tangentially into a whirl chamber 41 formed by the sprayer plate and the distance plate. Spill fuel is returned from the whirl chamber through an outlet 48 in the distance plate leading to apertures 49 in the distributer head and to the inner barrel 14. The burner barrels extend through a distance tube (not shown) bearing an impeller at its forward end. The burner fires through a port in a furnace wall. Air is supplied to the furnace port by a register disposed in a wind-box and comprising doors operated by spur-wheels, linkages and a handle. Fig. 7 (not shown) discloses a non-spill type atomizer having a conical outlet from a swirl chamber fed by tangential passages. Fig. 9 (not shown) discloses a further non-spill type atomizer having a conical outlet and a swirl chamber defined by a cylindrical rearward extension of the sprayer plate. Fuel enters the chamber through axially-spaced tangential inlets which are uncovered in sequence by a plunger as the fuel pressure increases. The plunger is connected to a bellows and a biasing spring.

Each chain 7 is connected to a point 13 on a side member, and to a fixed part 8 on the <PICT:0900416/III/1> framework of the machine, and passes around upper (12 or 14) and lower 9 or 9 and 11) sprockets or pulleys mounted on the fixed framework of the machine, and over a sprocket or pulley 6 mounted on a cross member 5 pivotally mounted on the movable part of the ram to secure a balancing action.  The hydraulic control means for actuating the ram comprises a motor driven pump 17, valve means 22, 23 which can be set to direct a selected position of the flow of hydraulic medium to the ram 4a and the remainder to a reservoir 21, for extending the ram at a slow rate.  A by-pass valve 24 allows the ram to be extended at full speed, and a stop valve 25 enables it to be lowered rapidly, to immerse the articles carried by the member 3 in a vat positioned therebelow.  In a modification, the apparatus may be adapted to raise and lower a vat of liquid, carried on the lifting member, with respect to a fixed article supporting frame.

Abstract: 1,133,082. Laminates. COURTAULDS Ltd. 28 Feb., 1966 [1 March, 1965], No. 8628/65. Heading B5N. A laminate comprises a sheet of thermoplastic polymeric material, e.g. polypropylene, bonded to a layer of glass fibres and thermosetting resin, e.g. polyester resin, the bonded surface of the thermoplastic sheet having a multiplicity of integral filamentary protrusions. The protrusions may be formed by pressing the heated thermoplastic sheet against the surface of a cylinder provided with cavities and then drawing it away. The filamentary protrusions may be stretched to orient their molecular structure by making the cavities of a shape which will retain the ends of the protrusions until they are thinned down, or snap off or are cut off. The polyester and glass fibre layer may be applied as a woven, knitted or unwoven fabric with application of resin before and/or after the fabric, or as chopped strands applied by spray or by hand together with a liquid resin or prior to application of the resin. The lay-up is passed between rollers. Further fibre-resin layers may be added and the laminate may be used for building construction, ducting, tanks and vessels.

Abstract: 610,095. Fuel-injection pumps. RASMUSSEN, K. March 21, 1946, No. 8816. Convention date, March 16, 1940. [Class 102 (i)] [Also in Group XXVII] In a device injecting oil into an internal-combustion engine combustion chamber at a substantially constant rate, the pressure at the point of injection is lowered in one or more stages during the injection period by increasing the effective area for admission of the oil into the chamber. An injection pump plunger 1 has a collar 4 controlling an inlet passage 5, and passages 9, 10 connecting the spaces 8, 11 to grooves 15, 16, 17 co-operating with passages 12, 13, 14 leading to the combustion chamber. When the collar 4 on rising closes the inlet 5, fuel is sprayed at high pressure through the passage 12, the pressure dropping successively as the passages 13, 14 come into action. The injection ceases either when the edge 7 uncovers inlet 5 or when the grooves 15, 16, 17 pass the passages 12, 13, 14, rotation of the plunger varying the opening and closing of the inlet and delivery passages. The pump 2 is shown attached to a cylinder head, the passage 12, 14 having non- return valves and leading to injection nozzles in a combustion chamber.

Abstract: 878,011. Punching. BRITISH THOMSONHOUSTON CO. Ltd. March 4, 1958 [March 19, 1957; March 22, 1957], Nos. 8993/57 and 9481/57. Class 83 (4). In a punching press having a stripping sleeve surrounding a punch, the stripping sleeve is held in work-stripping position by a pair of latches in the form of flat plates or levers lying in planes perpendicular to the punch and movable into the return path of the stripping sleeve as the punch is withdrawn from the work. In a turret press in which punches 2 and dies (not shown) are carried by a rotatable frame 1, each punch has a T-shaped projection 7 which engages in a slot 6 in the press ram 4. The punch 2 is retained in uppermost position by a spring-loaded plunger 33 engaging a bevelled surface 32 of a key 14 fixed in the punch 2 and sliding in a keyway in the frame 1. Spring-loaded ball detents 36 in the punch engage indentations 39 in a stripping sleeve 12 so that when the ram 4 is lowered the punch 2 and stripping sleeve 12 move together until the latter contacts the work 9. Just before the punch 2 contacts the work 9, spring-loaded latches 20, 21 move into the path of the stripping sleeve 12 which is thus positively held while the work is stripped from the punch 2. The latches are depressed by the upper edges of keys 14, 15 fixed in the punch 2 and moving with lost motion in slots 18, 19 in the stripping sleeve 12. The stripping sleeve is lifted either by the keys 14, 15 or by a shoulder 39 on the punch. In a modification the latches are two pivoted levers spring-urged together and opened on the operating stroke by an enlarged portion of the stripping sleeve and on the return stroke after the work has been stripped from the punch by keys fixed in the punch. In a further modification the latches are operated by a member connected with lost motion to an auxiliary ram moving with the main press ram.
