Title: Improvements in or relating to fuel injection pumps for internal combustion engines
IPC: F02M59/26
Filed: 1941-07-04
Abstract: 549,981. Fuel-injection pumps. TRIGGS, W. W., (Soc. Anon. A. Saurer). July 4, 1941, No. 8483. [Class 102 (i)] In a fuel-injection pump in which the beginning and end of injection is positively controlled, by means of valves, or by means of apertures 7, 8 in the cylinder 2 co-operating with recesses 10, 13 in the piston 3, whereby at low speeds n<SP>1</SP> the delivery diminishes with decreasing speed, and at excessively high speeds nx the delivery diminishes with increasing speed (see curve B, Fig. 1), at the transition to idle running at a low speed, with simultaneous regulation of the pump to a larger delivery, the comparatively large admission aperture ordinarily provided is replaced by a smaller aperture, through which the pump chamber 11 is only partially filled in the region of the no-load speed but can be completely filled at a speed which is below this no-load speed, so that only the end of the injection is still controlled by the valve or by the piston, and in this range of speeds the delivery diminishes with increasing speed (see curve C). By adjustment of the quantity regulating members of the pump, the maximum quantity VA injected at a low speed may exceed the quantity Vm injected at full load, and therefore be suitable for starting the engine. In the form shown in Fig. 2, as the regulating rack 16 moves to the left, the quantity of fuel injected is first reduced by the recess 10 causing an earlier uncovering of the reflux aperture 8, and is then increased by an additional surface 9 which causes a later uncovering of the aperture 8. A spring stop 17 on the rack 16 rocks a lever 19 and projects into the conical filling aperture 7 the conical end of a spring-pressed needle 20 having a narrow bore 22 to reduce the size of the filling aperture, the starting injection being controlled by the surface 9. The needle 20 may be replaced by a rotary valve surrounding the pump cylinder 2 and controlled by the rack 16. In the form shown in Fig. 3a, the pump piston has a projection 24 with a small bore 25 to control the filling aperture 7, and a groove 26 whereby the engine can be stopped. In the form shown in Fig. 4a, the upper end of the piston 29 is formed with a step 30 and the. small filling aperture 28 for no-load operation is provided in the pump cylinder 27, the groove 26 being sufficiently large to dispense with the bore 14. The filling aperture 28 may be exteriorly adjusted, as by means of conical needles, whilst either of the apertures 25, 28 may be replaced by exchangeable nozzles. In the form shown in Fig. 6a, the filling aperture 7 serves also as a reflux hole, the reflux chamber 12<SP>1</SP> is not separate from the suction chamber 12, and a small filling aperture 33 for running light is arranged diametrically opposite the aperture 7.

IPC: F02M19/12
Filed: 1926-03-30
Abstract: 265,906. Seignol, E. Feb. 10, 1926, [Convention date]. Spray carburettors.-In carburettors wherein a primary carburetting means produces a rich mixture which is introduced into the air stream of a secondary carburetting means, the amount of rich mixture admitted to the secondary carburettor is controlled in accordance with the position of the throttle valve, and an air valve in the secondary carburettor adapted to be opened by the drop of pressure therein, has its opening retarded by a dash-pot or the like. The primary carburetting means comprises a venturi tube g to which fuel is supplied from a tank i through a pipe h which may communicate with the outer air through a series of orifices h<1>, h<2>, h<3> and a tube v. The rich mixture is conveyed through a pipe f to the seating j of a valve kand thence through a pipe e<1> and tube e to the engine side of the throat c<1> of a venturi c. Air may be admitted to the pipe e<1> in constant quantities through the bone of a screw t and in variable quantities through a passage u around the screw. The valve k is pressed towards its seat by a spring m and has a collar s engaged by the forked end of a bell-crank lever o, p pivoted at q. The other end of the lever is provided with an adjustable portion r which engages a cam n on the spindle of the throttle valve d. The actuating means are so adjusted that the valve k is slightly open when the throttle is closed so as to supply mixture for slow-running. To ensure good acceleration when the valve d is opened suddenly, the secondary carburetting passage a, Fig. 1, is provided with a suction-actuated hinged air valve w, the spindle x of which is connected through linkage y, z to the rod 1 of a piston 2 of smaller area than the air valve. This piston slides in a cylinder 3 which communicates with the atmosphere at 6 and with the engine side of the throttle d through a duct 4 controlled by a valve 5. The device serves to close the valve w when the throttle is closed and to prevent the valve from opening suddenly upon sudden opening of the throttle valve. Specifications 251,584 and 265,904 are referred to. Reference has been directed by the Comptroller to Specification 193,706..

Abstract: 366,958. Colour photography and kinematography. BAKER, T. T., The Hut, Hatch End, Middlesex, and SPICERS, Ltd., 19, New Bridge Street, London. Nov. 7, 1930, No. 8666/31 (divided application), and 858/31. [Class 98 (ii).] In the reproduction of a master picture transparency, made on regular or irregular pattern multicolour-screen sensitive material, by projection-printing upon similar sensitive material, an image of the master picture is focused upon the emulsion of the copy film by means of a lens of wide aperture, such as F/2, and therefore of such critical focus that the image of the master colour screen, which is formed in the plane of the colour screen of the copy, is sufficiently diffused to avoid the production of interference effects such as the moire effect. These effects may be avoided more readily by the addition of a plane-parallel sheet of transparent singly-refracting material such as window glass or photographic negative glass, of thickness preferably between <3>/64" and #" and having plain faces, which is placed in the projection system either in front of or behind the wide aperture lens. The lens may comprise two similar components, each of aperture F/4 and of focal length 180 mm., separated by a distance of 2 cm., and it is provided with a micrometer focusing adjustment. Reference is made to reproduction with projecting lenses of aperture F/16 to F/32. Specifications 322,231, 322,432, 324,043, and 337,041, [all in Class 98 (ii), Photographic processes &c.], are referred to.

March 31, 1927, Impulsc transmitters. - An impulse cam is frictionally coupled to an auxiliary cam by one or more loose washers capable of movement independently of either cam, and one or more loose washers may be interposed between the auxiliary cam and a spring member which holds the parts in frictional engagement. The impulse cam 3 and spring bar 2 are fixed to the shaft 1, and the auxiliary cam 11, which serves to mask the cam 3 during setting movements and part of the return movement, is mounted on a sleeve 8. The loose washers 15, 16, 17 are also mounted on the sleeve 8 and the parts are held in frictional engagement by a spring washer 4 and nuts 6. An arm 5 carries an insulating bush 10 normally engaging the " off-normal " springs. The washers may be non-metallic, such as felt, or metallic, and the washer 17 may rotate with the shaft 1. The impulse springs, or members controlling them, engage the cams at z, and during the setting movement in the counter-clockwise direction, the cam 11 moves with the cam 3 until a projection 12 engages a fixed stop 13 after which the requisite number of slots in the cam 3 are exposed. On the return movement the cams move together until the cam 11 is stopped by the projection 14 when operation of the impulse springs commences. Specification 178,936 is referred to.
Patent GB-695593-A (GB)
Title: Improvements in or relating to the refining of fatty oils
IPC: C11B3/06
Filed: 1951-04-17
Abstract: Free fatty acids are removed from fatty oils by combining a stream of the oil with a stream of aqueous caustic soda solution, the contact time not exceeding 5 seconds, and then separating the soap stock formed from the neutral oil by centrifugal force.  The strength of the caustic soda solution is at least 20 DEG  B<\>ae and preferably 22 DEG  to 30 DEG  B<\>ae, and the flow is so proportioned that it is at least substantially stoichiometrically equivalent to the free fatty acid present in the oil, this being the preferred proportion. The oil may be heated to between 140 DEG  and 160 DEG F before combining it with the caustic soda solution.  Mechanical mixing and violent agitation are preferably avoided, the streams being combined in a pipe under conditions of turbulent flow.  A centrifugal separator similar to that described in U.S.A. Specification 2,138,468 may be used, employing water to assist in the removal of separated soap stock from the sides of the rotor (see Group II).  Oils which may be refined by the process include cotton seed oil, soya bean oil, peanut oil, corn oil, sunflower seed oil, sesame oil, rape seed oil, coconut oil, babassu oil, palm oil, palm kernel oil, linseed oil, tallow, lard, grease, fish oil and whale oil.  The oils may be degummed or decolourized either before or after refining, by any known process.

IPC: F02D1/00
Filed: 1956-03-22
Abstract: 788,894. Starting direct injection engines. SATZGER, E. March 22, 1956, No. 8945/56. Class 7(3) A stop 14 normally determining,the fullload fuel supply limit is moved sideways at starting, to permit an excess fuel supply, by an eccentric ring 3 on the pump shaft 2, which ring is moved by centrifugal force to a position concentric with shaft 2, when the engine is running, to permit the stop 14 to return to its normal position. The member 3 has a slot 4 engaging flats 5 on the shaft 2 and -is normally urged to its eccentric position by a spring 7. Holes 8 in the ring 3 ensure that the centre of gravity 9 always remains on the side of the axis of rotation opposite the eccentric portion so that when rotated the centrifugal force b urges the ring to slide sideways to its position concentric with shaft 2. At starting speed the eccentric ring 3 engages push rod 15 to lift the stop 14, permitting a co-operating sleeve 19 adjustably mounted on the pump control rod 10 to pass through stop 14 whereby the control rod moves to its excess supply position limited by engagement of a ring 20 with the stop 14.. When the engine fires the ring 3 moves to its concentric position and after movement of the rod 10 to the right the. stop 14 returns to its normal position in the path of the sleeve 19, the push rod 15 being then out of contact with the ring 3. The ring 3 may be counterbalanced by a similar ring 3<SP>1</SP>, Fig. 4, aranged at the side of, and with opposite eccentricity to, the ring 3.
