Title: Improvements in devices for supplying starting fuel to internal combustion engines
IPC: F02N99/00
Filed: 1942-11-30
Abstract: 561,359. Supply of starting-fuel to internal - combustion engines. AKTIEBOLAGET AEROTRANSPORT. Nov. 30, 1942, No. 17025. Convention date, Dec. 1, 1941. [Class 7 (v)] A device for supplying starting fuel to internal-combustion engines, particularly aircraft engines, by means of an injection nozzle opening into the inlet channel of the engine, has a closed tank containing starting fuel under pressure removably connected to the injection nozzle'through a valve, which is normally closed but can be opened from a remote control on starting the engine. The tank may be about two-thirds full of high vapour-pressure fuel and filled with inert gas under pressure. The tank is removably mounted in a bracket 2 adjacent the engine and is connectible to mounting and coupling means 3 also carried on the bracket. A stationary part 5 screwed to a fitting 7'includes a connecting nipple 11 and non-return valve 10 and has a longitudinal bore 8. The tank has a flanged neck 15 enclosing sealing washers 18, 19 and an inturned member 17 which retains a .spring-pressed washer 21. A part 22 .of the tank encloses a spring-pressed valve disc 24 which when the tank is clear of the coupling engages the packing 19 and .seals the tank. A coupling .socket 6 retains two segmental pieces 13 against the bottom of the member 17, the arrangement ,being .such that the tank may !be quickly coupled by slipping the coupling end over the stationary part 5 and rotating the coupling 6 so that the segments 13 engage under segmental shoulders 12 on the part 5. When the coupling is made, the disc 24 is lifted so that fuel can flow through the bore 8 and through the hose 43, Fig. 5, to the injecting nozzle unit which consists of a fitting 26 provided with an atomiser 28. A housing 30 screwing into fitting 26 carries a slidable iron core 33 operated by a solenoid 32. The core encloses the stem 34 of a needle valve 31 guided by pins 35 on the core. The -stem carries a perforated disc 37 having slight clearance in the housing. A spring 39 normally holds the valve closed, but when the solenoid is energized the iron core compresses a spring 38 and then opens the valve against the fuel pressure. The solenoid is -preferably connected in parallel with the starting coil or with the starter motor so that starting fuel is automatically supplied when the starter is pressed. 'When the fuel tank is exhausted, it may be quickly removed and replaced by a fresh tank. Instead of being mounted on the plane, the tank may be mounted on a servo carriage on the airfield.

Title: Improvements in or relating to bistable magnetic devices and digital data stores including such devices
Inventor: ELSON DAVID WILLIAM
IPC: G11C5/02
Filed: 1961-05-10
Abstract: 937,776. Circuits employing bi-stable magnetic elements. GENERAL ELECTRIC CO. Ltd. May 10, 1962 [May 10, 1961], No. 17030/61. Class 40 (9). [Also in Group XXXV] Bead-out of the direction of magnetization along the easy axis 5 (Fig. 1) of a magnetic thin film is effected by superimposing on a transverse magnetic field a temporary change thereof in a selected sense (which preferably increases the cross magnetization to a point at which the remanent magnetization vector is turned perpendicular to the easy axis) the leading edge of the pulse produced in a conductor 4 by the consequent temporary change of magnetization along the easy axis producing an indication of the sense of the change (and hence of the information recorded in the film 1) in detector 8. The transverse field may be produced by a current in conductor 3 or by a pair of coils or a permanent magnet, the temporary change in the transverse field being produced by a pulse in conductor 3. Fig. 3 illustrates a data store having a continuous thin magnetic film 11 on a polished aluminium plate 12 and sets of conductors 13, 14, which are respectively parallel and perpendicular to the easy axis, on flexible polyethylene terephthalate webs wrapped round the plate 12. Direct current is passed (if desired only during reading) through selected conductors 13 by triggering selected pairs of transistors 18, 19 (Fig. 4) so that D.C. is then supplied from transistor 20, reading pulses are then superimposed on the D.C. in these conductors, by transistor 21 in response to control pulses applied to primary 22 of transformer 23, to read out a stored word. A word is written into the selected column, if read out is destructive, by applying pulses to conductors 14 (Fig. 3) overlapping the trailing edges of the read pulses applied to conductors 13, the amplitude of the write pulses being insufficient to cause switching of any device in the absence of an overlapping read pulse. Instead of using the leading and trailing edges of the same pulse for reading and writing separate pulses may be used. Specification 919,022 is referred to.

Title: Improvements in Ejector Apparatus for use in connection with Vacuum Brake Apparatus on Trains and the like.
Inventor: WILLANS GEORGE HERBERT
IPC: B60T13/46
Filed: 1916-11-30
Abstract: 112,290. Willans, G. H., and Luard, E. S. Nov. 30, 1916. Fluid - pressure. - Ejector apparatus for vacuum train brakes has air and steam valves of the lift or poppet type controlled by a single handle and connexions which are disposed outside the casing. The small ejector is cut off from the train pipe when the m a i n air valve is opened, by holding down the check valve of this ejector. The steam valve is balanced. The steam supply pipe 6 is constantly open to the chamber 9 of the small ejector 2 and communicates with the chamber 15 of the large ejector 3 through the lift valve 13. The air chamber 23 of the large ejector communicates through the check valve 26 with a chamber 18 open by channel 31 to the train pipe at 4. The main air valve 19 is arranged in the chamber 18. A passage 30 extends from the channel 31 and connects through the check valve 29 with the chamber 28 which is continuous with the air chamber 33 of the small ejector 2. A passage 35 with a check valve 37<a> and a pipe connexion 36<a> connects the chamber 28 with the upper chambers of the engine brake cylinders. The valve-operating mechanism comprises an arm 55 rocking on a pivot 53<a> and passing through slots 45, 47 in the stems 13<a>, 19<a> of the steam and air valves 13, 19. A cam 55 formed on or secured to the arm 55 is engaged by a cam 52 on the spindle of the handle 51. A second rocking arm 56 pivoted at 56<a> passes through the stem of the air valve 19 and a rod 62 working above the stem of the small ejector check valve 29. In the neutral or running position shown, the small ejector exhausts the train pipe through the pipe 4, channel 31, passage 30, check valve 29, and chambers 28 and 33. Movement of the handle 51 to the right raises the valve 19 and air is admitted to the train pipe to apply the brakes through the holes 21 and bv way of the chamber 18 and channel 31. At this time, the check valve 29 is pressed on to its seat by the arm 56 and rod 62 so as to cut off the small ejector from the train pipe, the connexion of this ejector with the upper chambers of the engine brake cylinders being however left open. To release the brakes, the handle 51 is moved to the left to lift the valve 13 and admit steam to the chamber 14 of the large ejector 3: the train pipe is then exhausted by way of pipe 4, channel 31, chamber 18, check valve 26, and chamber 23. The stem 13<a> of the steam valve 13 is of large diameter so that this valve is practicallv balanced and its actuation facilitated. A valve 63 in the pipe 36a operable by a hand-lever 69 serves to admit air to the upper chambers of the brake cylinders to release the engine brakes. The small ejector steam valve 41 is controlled by the lever 43. The small ejector may have an annular steam jet instead of the conical jet shown. Fig. 7 shows an alternative combined annular and central jet for the large ejector shown in Fig. 3. for which a simple annular or conical jet may also be substituted.
