Title: Fuel injection systems
IPC: F02M69/14
Filed: 1976-04-07
Abstract: 1537103 I C engine fuel injection system ROBERT BOSCH GmbH 7 April 1976 [8 April 1975] 14022/76 Heading F1B A fuel injection system for a spark ignited I.C. engine with fuel injection into the air intake pipe 1, Fig. 1, comprises an air-flow measuring unit 3 in the form of a leaf, attached to a carrier 24 fast with a bush 25 and hinged to a bearing axle 7 upstream of a throttle valve 5, and arranged to  suffer a displacement against the force in a coil spring 47, Fig. 2, proportional to the quantity of air passing through the intake pipe to operate a fuel metering valve 29 comprising a control slot 26 in bush 25 throttled by the edge 28 of a groove 23 in axle 7 for delivery of a quantity of fuel proportional to said displacement, the pressure difference across the valve being maintained constant by a different pressure valve 18. An electric pump 14 delivers fuel to a chamber 17 of valve 18 which is of the flat seat type having a fixed element 43 and a diaphragm 39 acted upon by a spring 40 the force of which is governed, according to engine operating conditions by, for example, an electromagnet 41, the magnetic force of which may vary as a function of engine temperature or oxygen content in the exhaust pipe. Alternatively, the spring force may be controlled by a bi-metallic spring acting on spring 40 as a function of engine temperature. The fuel subsequently passes to metering valve 29 via line 19, chamber 20 and passage 22, metered fuel passing via grooves 27 and 30 in bush 25 and annular groove 32 in axle 7 to a passage 33 in the leaf, from which it is injected into the air stream in inlet pipe 1. Line 37 and passage 36 communicate with groove 32 and act as the return fuel path to valve 18. The fuel may be injected via one or more injection nozzles 34, or there may be a single nozzle forming a gap extending over almost the whole width of the side of the leaf; alternatively, an injection valve may be employed. Under all but low load conditions, air may be mixed with the fuel prior to injection, by way of a passage 53 which connects with an air hole (54), Fig. 4 (not shown), in carrier 24. A damper 8 reduces the effects of pressure fluctuations in the induction pipe produced by the engine suction strokes.

Title: Process for preparing calcium, strontium, barium or lead salts of acid sulphuric acid esters with more than six carbon atoms in the molecule
Filed: 1938-05-13
Abstract: 504,977. Lead sulphonates; alkaline' earth sulphonates ; emulsifying-agents ; wetting - agents. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. May 13, 1938, No. 14393. Convention date, ,May 31, 1937. [Classes 1 (i) and 1 (iii)] [Also in Group IV] In a process for the manufacture of calcium strontium, barium and lead salts of acid sulphuric acid esters from materials containing free sulphuric acid and acid sulphuric acid esters having more than six carbon atoms in the molecule, the said material is treated with suitable compounds of the above metals in the presence of one or more alkanols and /or ketones with less than five carbon atoms in the molecule, the precipitated sulphates are removed and the solutions worked up into pure sulphuric acid ester salts. The initial material may be partially freed from free sulphuric acid by washing it with a small amount of water which may be carried out in the presence of oxygen-containing organic compounds containing from five to fifteen carbon atoms, e.g. higher molecular alkanols. The metal compound and alkanol or ketone may be added separately to the ester or they may be mixed together and added to the ester as a thin stream. The reaction may be carried out at elevated pressure and temperature, up to the decomposition temperature of the salts formed but preferably temperatures of 60 to 100‹ C. are used. Before filtration a hydrocarbon or mixture of hydrocarbons such as pentane or benzine may be added to the suspension in order to dissolve suspended droplets of higher boiling oil constituents present in the reaction mixture which would otherwise clog the lilter cake. The insoluble precipitate is removed by filtration or centrifuging and may be washed. The mother liquor is concentrated by evaporation after the removal of the hydrocarbon and forms a paste-like mixture of metallic ester salt. The products may be used as emulsifying agents, wetting agents, foaming agents, so-called flooding agents in the petroleum industry, demulsifying agents and detergents. In examples the initial material is obtained by treating a distillation product of cracking paraffin wax in the vapour phase which contains alkenes with 13-18 carbon' atoms for one hour at 0-5‹ C. with twice the theoretical quantity of sulphuric acid. The process is mainly concerned with the production of the ester-salts of alkanols and alkenes, but may also be applied to the acid sulphuric acid esters of unsaturated alcohols and mixed aliphaticcyclic hydrocarbons with one or more double bends in the aliphatic chain. Suitable alkanols or ketones with less than five carbon atoms are ethanol, propanol, butanol, acetone and methyl ethyl ketone. Suitable compounds of the metals are the hydroxides and carbonates. Specification 480,904, [Group IV], is referred to.

A loading-machine includes a shovel, the rear end of which extends into and is pivoted to a trough which is itself pivoted to the main frame, the arrangement being such that the upward and downward movements of the shovel are limited by means on the trough and shovel. The shovel 32, Fig. 2, is pivoted on a shaft 31 extending across the trough 22 which is itself pivoted to a shaft 18 mounted in the side walls 10, 11 of the machine. A cross-plate 16 connected to the walls 10, 11 closes the end of the machine and a plate 17 the bottom. This latter plate is pivoted on the shaft 18, has side flanges 19, 20, Fig. 1, outside the walls 10, 11 and is supported by wheels 21. The side walls of the trough 22 are connected by a cross bar 26 having upstanding lugs 29, 30. The side walls of the shovel are connected by cross members 37, 38, the former of which has upstanding lugs 50, 51. Tie rods 52. 53 are passed through the two pairs of lugs and are secured by nuts 54, 55 to the lugs 29, 30. Rubber cushions 58 are placed between the heads 57 of the rods and the lugs 50, 51. The cross member 38 has upstanding ears 42 in which a tackle block 40 is mounted bv a swivel connection. The block 40 has a hook 43 to which one end of a rope 44 is attached. This rope, which is used for rocking the shovel, is led round a sheave on the block 45, a sheave on the block 40 and below a second sheave on the block 45. Brackets 63 on walls 10, 11 limit the downward movement of the trough and shovel. The machine is drawn forward by chains 60, 61 connected to a cable which is passed round an anchored tackle block.

Abstract: 274,432. Schmid, E. July 14, 1926, [Convention date]. Driving-gear.-The piston 1 drives on to two crank shafts 6, 7 through a beam 3 rocking on the piston, and connecting-rods 4, 5. The two shafts are geared together so that the shaft 7 rotates at half the speed of the shaft 6, which is the speed of the power shaft. The piston controls the exhaust ports and overruns the admission ports 15, the entry of charge under pressure being regulated by a valve 12. As a consequence of the driving used the piston has a movement represented by the curve shown in Fig. 6. Explosion occurs at top dead centre marked a and exhaust commences at point b ending at c ; the movement of the piston is very small during the long charging period which is represented by the curve d to e. If desired, charging may commence while the exhaust port is still open.
