Title: An improved method of operating an internal combustion engine
IPC: F02D17/00
Filed: 1935-11-01
Abstract: 453,034. Spray carburetters ; chargeforming devices. SARDA, R. U., 125, Calle Urgel, Barcelona, Spain. Nov. 1, 1935, No. 30193. Convention date, April 1. [Classes 7 (ii) and 7 (iii)] During the closing movement of the carburetter throttle valve, additional air is admitted to the induction pipe as the closure is initiated and the addition increases progressively until the throttle reaches its idling position, whereupon the admission is cut off. A shaft 12 rotated in unison with the throttle valve carries a ratchet disc 17, the teeth of which are adapted to engage a tooth 18 on a disc 16 loosely mounted on the shaft 12 and pressed against the disc 17 by a spring 24. The disc 16 is coupled to a piston valve 10 which opens as the throttle valve closes, until, at the idling position of the throttle a fixed projection 23 engages a stud 22 on the disc 16 to separate the discs and permit a spring 21 to close the valve 10. Simultaneously, a disc 11 on the shaft 12 may operate a valve 9 in consonance with the throttle valve. Air for idling is supplied past a valve 5.

Title: Process for the manufacture of technically pure iron
IPC: C21C5/32
Filed: 1952-11-28
Abstract: Technically pure iron, i.e. cron containing small amounts of the usual impurities, is produced by blowing oxygen from above into or on to the melt and keeping the slag temperature below that of the melt by the addition of cold slag-forming substances, e.g. limestone, burnt lime, or cold slag.  The slag-forming substances may be in pieces of nut or fist size and may be added all at once before the end of the process or may be added continuously in small amounts. The finished iron, in an example, is stated to contain 0.02 per cent C, 0.15 per cent Si, 0.15 per cent Mn, 0.015 per cent P, and 0.02 per cent S.

Patent GB-762825-A (GB)
Title: Improved pressure-responsive apparatus
Inventor: DOLZA JOHN
IPC: F01D17/08
Filed: 1954-10-22
Abstract: 762,825. Gas turbine plant. GENERAL MOTORS CORPORATION. Oct. 22, 1954, No. 30469/54. Class 110 (3). [Also in Group XXIX] A gas pressure responsive device includes a bellows acting through a pair of lever arms, one of which is adjustable, and a cam wherebymovement of a controlled member may be effected in response to a desired, e.g. logarithmic, function of pressure. In an embodiment, applied to control of the fuel supply to a gas turbine engine in accordance with compressor inlet and delivery pressures, the inlet pressure acts on the exterior of a bellows 125 (Fig. 15) which has a connection 134 with a lever 57<SP>1</SP> mounted on a spindle 61<SP>1</SP> which carries a lever 141<SP>1</SP> (Fig. 18) connected with a control valve 144 for a servo piston 160. The bellows 125 is evacuated and spring loaded internally. Movement of the valve 144 causes a corresponding movement of the servo piston due to movement by the piston of a ported sleeve 153 with which the valve 144 coacts. The sleeve 153 carries at its end a roller 175 coacting with a cam lever 177 pivoted on a spindle 178 and having an adjustable abutment 183 with a spring-loaded lever 180 also pivoted on the spindle 178 and engaging at its lower end a rod 188. The cam surface 176 of the lever 177 is shaped so as to provide the required relation between pressure and movement of the member 188. Compressor delivery pressure acts through a connection 108 (Fig. 4) on a diaphragm 101 which actuates a valve 90 controlling the pressure of oil in a cylinder 54 containing a piston 53 which is connected to an evacuated bellows 42 loaded by springs 47, 49. The pressure in the cylinder 54 reacts through ports 70a on the diaphragm 101 so that the pressure in the cylinder and consequently the position of the piston 53 are related to the compressor delivery pressure, the bellows 42 being of the same area as the piston 53 so as to eliminate the effects of variations of ambient air pressure. The piston 53 is also connected to a lever 57 mounted on a shaft (not shown) which carries a lever similar to the lever 141<SP>1</SP> and which actuates a control valve and servo piston operating an output member through a cam lever and roller assembly similar to that shown in Fig. 18. The two servo pistons 160 are mounted side by side in a common housing and the two output members may be parts of a device whose functioning is to be made dependent upon the compressor inlet and discharge pressures.

Abstract: 1277641 Fluid-pressure servomotor systems I J CYPHELLY 18 June 1969 [27 June 1968; 30 Oct 1968] 30836/69 Heading G3P A fluid-pressure amplifier comprises a throttling disc 4, Fig.1, movable in response to adjustment of a valve means 10, 11 in a housing 9 to vary simultaneously the width of a gap 6 through which fluid is supplied from inlets 3 to an outlet port 13, Fig.2, and the width of a control gap 5 through which fluid from the inlets flows to the valve means. The hydraulic resistance of the gap 5 is greater than that of the gap 6 which has a labyrinthine seat 8 and the control to load flow ratio may be 100:1. In Fig.6, the load pressure area 8 is separated from the control pressure area 7 by a bellows 16 and a wall forming the control throttling seat 19 is located radially within an annular load throttling seat 14. In a modification, the control throttling seat consists of an adjustable screw so that a control member, such as a flapper valve, can completely close the load circuit. In Fig. 8, the lower face of the disc is divided by bellows 23 and 24 into an inlet pressure area 3 and an area 25 that is kept pressure free by a vent 21. Load pressure in the space 26 is led by a passage 27 to a compensating space 28 between bellows 16 and 22 so that the position of the disc is independent of load pressure. Since the feed pressure of line 1 is divided only as a function of the control pressure at 17 the arrangement may be used as a low output impedance pressure divider. In a modification, a single control pressure regulates a number of load pressures. Amplifiers similar to those of Figs.6 and 8 may be connected in series and be controlled by an electrically heated resistance wire (29), Fig.10 which varies the viscosity and hence the flow rate of fluid in a control bore.

Title: Improvements relating to shedding mechanism for circular looms
IPC: D03D37/00
Filed: 1935-11-09
Abstract: 465,609. Circular loom-shedding mechanism. BRITISH CELANESE, Ltd., BENNETT, J. W., HALE, F. C., and POOL, W. Nov. 9, 1935, No. 31044. [Class 142 (ii)] The warp threads are deflected in turn from their normal line by rollers 54, 60 and the light flat metal healds 24 consequently tend also to be moved outwards (to the left in Fig. 3), but the movement of certain of these is restrained by stop members 45, adapted to be selectively interposed in their path. Sheds are thus formed which the shuttle noses can enter and expand. In a loom with a rotating shuttle, the healds rest on wire rings 22 and their forked inner ends embrace rings 22 on fixed radial plates 21 on brackets 18 on stationary columns 19, whilst the rollers 54, 60 are. carried by a rotating ring 56. Columns 48 on the rotating ring 15 carrying the vane wheel mechanism for actuating the shuttles support a ring 49 furnished with brackets 50 connected by an annular ring 51 carrying rollers 53 engaging the rollers 54, whereby the ring 56 is rotated, overrunning thereof being prevented by rollers 59. The stop members may comprise pivoted blades movable by toggle devices described having diamond-shaped members 32 operated by cams 64 inserted in slots in the brackets 50, which move around the loom, the toggle devices being carried by box-like brackets 30 on annular rings 28, 29 fixed to the stationary plates 21. The notched ends of some of the blades are thereby interposed in the path of some of the banks of healds, for example, the second, third, fifth and sixth from the top, the remaining banks of healds being free to move to the left. Rollers 62 ensure the return of the healds to normal position by inwardly deflecting the outer sheet of warp threads. The rings 22, 23 are spaced by members 27. In one modification described, an intermittentlyrotated pattern drum is provided on each face with cams for controlling the toggle-lever devices. In another, a frame 78 is slidable up and down in slots in fixed plates by means of a lever 87 carried by a support moving around the loom, and operated by plate cams 91 with inclined edges on an endless pattern chain on the loom frame. The upper horizontal plate 80 on the frame 78 can thus be placed in restraining position opposite any bank of healds. In the Provisional Specification it is stated that the invention may be applied to looms with stationary shuttles and to looms in which the shuttles and warp rotate in opposite directions. An arrangement is also described wherein the healds lie in slots between arcuate strips lying one above another and forming segments of two coaxial cylinders. A slotted plate is movable up and down by a cam to obstruct the motion of all but one or more of the banks of healds. The cam may be vertically slidable under the action of another cam which may be fixed or movable under the control of a dobby chain, jacquard cord, or selecting drum, &c. Each heald may comprise a pair of wires. Various arrangements of pivoted stops, and cams comprising fixed or movable pegs are described.

Title: Process for the production of gases containing hydrocarbons
Inventor: FOWLER ROY
IPC: C10G47/00
Filed: 1965-07-23
Abstract: A combustible gas containing gaseous hydrocarbons of which 20 vol. per cent at least are C2 or higher hydrocarbons, is made by catalytically reacting an H2-rich gas containing water vapour or mixed with steam at 400 DEG  to 1000 DEG  C. with a normally liquid hydrocarbon, e.g. an ash-free distillate oil, which may be added to the H2-rich gas in liquid or vaporized form.  The composition of the final gas is controlled by controlling the hydrogenation and reforming reactions, e.g. through choice of catalyst and proportion of steam in the H2-rich gas.  The reaction may take place at atmospheric or superatmospheric pressure, and catalysts mentioned are one or more of Ni, Cr, Co, Mo, W, V, Cu, Pt and Pd on alumina, magnesia and silicate supports.  Steam may be added to the H2-rich gas.  In an example, the H2-rich gas is made by reacting a naphtha with steam over a Ni catalyst, and adding further naphtha to the gas for reaction at 585 DEG  C. over a refractory-supported Ni/W catalyst, the final gas containing 22.1 vol. per cent CH4 and 6.8 vol. per cent C2H6 (dry basis).
