Title: Improvements in devices for injecting fuel continuously into the induction pipe of an internal combustion engine
Inventor: MENNESSON ANDRE LOUIS
IPC: F02M69/46
Filed: 1961-11-28
Abstract: 962,829. Fluid-pressure servomotor systems. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. Nov. 28, 1961 [Dec. 21, 1960], No. 42541/61. Heading G3P. [Also in Division F1] Fuel is continuously injected into an I.C. engine induction pipe 1, Fig. 1, downstream of a manual throttle valve 2 by a pump 4 connected to a calibrated orifice 10, upstream of which is aligned a smaller calibrated orifice 11 and a chamber 8, the degree of opening of which to a surplus fuel pipe 14, and hence the injection pressure, is determined by a spring-loaded valve 12. Upstream of the throttle valve 2 is a spring-urged lift valve 15 which continues to open until the negative pressure between the valves 2 and 15 balances the force of the spring 19 loading the valve 15. The valve 12 is attached to a pair of diaphragms 30, 31 and actuated by admitting fluid to the space therebetween through orifices 25, 26 and 33; orifices 25 and 33 are open to atmosphere, the area of the latter being determined by the position of a spring-opened valve 36 which is movable towards the closed position by a lever 39 on the throttle valve 2; orifice 26 is variable by a rotary, or as shown a needle valve 28 integral with the valve 15. The valve 36 may also be adjusted by supplementary factor e.g. the negative pressure in the induction pipe downstream of the throttle, the temperature of the ambient oil or the temperature of the engine lubricating oil or exhaust gases. In various modifications, the valve 15 is constituted by a piston-actuated plug-valve, a horizontal lift valve or a butterfly valve 15b, Fig. 5, on an eccentric spindle 24 having a counterweight 19b; the spindle 24 is provided with a roller 40 for actuating the needle valve 28. The orifice 25, which opens to the engine air intake upstream of the butterfly valve 15b, may be variable in dependence upon the position of the butterfly valve 15b, in which case the orifice 26 is fixed. The orifices 10, 11 open obliquely into the induction pipe. The air-fuel mixture may be adjusted by means in addition to or instead of the valve 36 for ensuring cold starting.

In a cable tray of the type consisting of side rails separated by ladder-like rungs (11), Fig. 2, (not shown), which engage in the lower longitudinal margin 7 of each rail, the rungs are provided with tongue-like extensions 19 which pass through holes 18 in the side rails so that the rungs cannot rotate. In the arrangement shown the holes are H-shaped and the side rails are clamped to the rungs by through bolts 15 and washers 20 which fit over the projecting ends of the tongues so as to locate the bolt centrally in the rung, the whole being held together by end nuts. The washers may be mounded or saucered and made of spring stainless or other steel 20 so as to act as spring washers. Depressions 22 in the upper margin of the rail structure correspond with stretching produced in the lower by hole formation. The side rails may be extruded or formed by rolling and may have a hook-shaped upper margin from which the trough may be supported.

Filed: 1974-10-03
Abstract: 1474703 Magnetic storage devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Oct 1974 [6 Oct 1973] 42930/74 Heading H3B Magnetic bubble domains of two distinct and stable sizes, and which may represent the binary digits zero and one respectively, are present simultaneously in a layer of magnetic material, the area of the larger bubbles being at least 15% and at most 125% greater than the area of the smaller bubbles. The bubble size is determined by a domain guiding structure consisting of an overlay of two or three permalloy strips, a two permalloy strip arrangement 2, 3 for small and large bubbles 5, 6 being shown in Fig. 1, while Fig. 2 shows a three strip arrangement 12, 13, 14 for small and large bubbles 16, 17. By representing binary data with bubbles of two different sizes all possible bubble positions in the magnetic layer 1, 11 may be occupied. A small bubble 35 coupled with a single permalloy strip 32, Fig. 4a, may be expanded to a large bubble 36, Fig. 4b, by a current pulse in a conductor loop 34. Similarly a current pulse of reverse polarity in a conductor loop 44, Figs. 5a and 5b, may be used to contract a large bubble 45 coupled with two permalloy strips 42, 43 into a small bubble 46. The bubbles may be propagated along the length of the permalloy strips by a varying magnetic field, propagation being effected by a T and I bar permalloy pattern 4, Fig. 1, or as permalloy angel fish pattern 15, Fig. 2. Alternatively the domain guiding structure and propagation pattern may be combined as shown in Fig. 3, propagation being effected by current in a convoluted conductor 24 while the direction of propagation is determined by the spatial positions of projections 25 on the permalloy strip 22. For reading a bubble with discrimination as to size a permalloy strip 56, Fig. 6, connected to gold conductors 57, 58 is sufficiently adjacent to one strip 53 of the domain quide structure to detect a large bubble by induction but not a small bubble.

These feed amplifiers Tr2, Tr5 whose outputs substantially cancel each other in the receiver H. Incoming signals are extended via capacitor C2 to only one amplifier Tr2 so that these are supplied to the receiver. A portion of the input signal appears across W2. and is hence applied to Tr3, Tr3 but this is of, little consequence.

Title: Process for the manufacture of a carboxylic acid ester of an alkali metal or alkaline earth metal salt of a hydroxyalkane sulphonic acid
IPC: C07C309/12
Filed: 1961-12-15
Abstract: Esters of alkali metal and alkaline earth metal salts, hydroxy-alkane sulphonic acids with carboxylic acids are prepared by heating a mixture of an alkali- or alkaline earth-metal salt and a carboxylic acid within the range 150 DEG  to 200 DEG  C. whilst introducing a quantity of gaseous hydrogen chloride such that saturated aqueous hydrochloric acid distils from the reaction mixture.  The hydroxy-alkane sulphonic acids may be monohydroxy, preferably containing 1 to 10 carbon atoms, with branched or straight chain alkane radicals containing the hydroxyl and sulphonic acid groups bound to any carbon atom, being more especially straight chain 2-hydroxy-alkane sulphonic acids.

The carboxylic acids may be aliphatic or araliphatic, straight or branched chain acids which may contain inert substituents and which are generally liquid at the esterification temperature, being more especially fatty acids containing 8 to 22 carbon atoms.  Polybasic acids and mixtures of carboxylic acids obtainable from natural products, e.g. tallow, coconut oil, or oxidation products of paraffins may also be used. The reaction is preferably carried out at 160-180 DEG  C. with 1/4 to 1 mol. of HCl per mol. of fatty acid and with the HCl mixed with an inert gas (e.g. N2 or CO2) and added in gradually decreasing quantities until only inert gas is added.

The breaker structure may, as shown in Fig. 2, consist of two plies 16 each having a fold line 15 at a respective edge of the structure and two free edges 17, 18 at the other edge of the structure, one of which free edges-either the radially inner or outer-overlaps the other, the acute cord angles in this case decreasing continuously from the free edges, where the angles are, e.g. 33-45 degrees, to the fold line. Alternatively the breaker structure may consist of a single ply folded along two fold lines to form an S-shape (Fig. 5, not shown) or C-shape (Fig. 6, not shown) in radial section, or a shape as shown in Fig. 7 in which two free edges 400, 401 of the ply overlap one another. In a further embodiment (Fig. 8, not shown) the breaker structure is formed from a flattened tube of parallel cord fabric. The tyre may be made by forming the carcass 11 on a tyre building drum; superimposing the sidewall and tread portions 13, 20 and the breaker structure on the carcass either in the manner shown in Fig. 2 or such that both the tread 20 and sidewall portions lie radially outwardly of the breaker structure, the width of the breaker structure being selected so that in the finished tyre it will be close to that of the ground contacting surface of the portion 20 although it may initially be greater than the width of the ground contacting surface; then expanding the tyre blank so assembled to toroidal form whilst maintaining the breaker structure flat in radial section, thus causing the cords of the breaker structure ply or plies to assume acute cord angles which decrease in the manner specified above; and finally vulcanizing the expanded blank. The contacting parts of the various components of the blank may be coated with a lubricant, e.g. zinc stearate, to facilitate relative motion therebetween on expansion of the blank.
