Abstract: 714,015. Spray carburetters; treating charge. SABETAY, D. Oct. 22, 1952 [Feb. 28, 1952], No. 5285/52. Classes 7(2) and 7(3) A fuel-air mixture is prepared by adding to fuel in a vapour or gaseous state air including oxygen in an active state, i.e. ozone or nascent oxygen, and the mixture is subjected to the action of magnetic forces. A mixture of air and ozone from an ozonizing apparatus 1 is mixed with fuel vaporized or gasified by heated plates 9, 10, arranged immediately adjacent a fuel nozzle 7. The ozoniser 1 comprises earthed tubes 4 each with a central electrode 5 at a voltage of e.g. 10,000 to 15,000 volts obtained from an engine ignition coil, and the plates 9, 10, are preferably of copper or brass heated electrically. The mixture of air, ozone, and fuel vapour flowing to the engine is directed by a deflector 15 to drive a mixing wheel 14 arranged in the magnetic field between the poles 11, 12 of an electromagnet or permanent magnet. The mixture next passes through the electrical field between two electrodes 16, 17 connected to an accumulator so as to have a potential difference of six to twenty-four volts. The ozone may be added after the vaporized fuel is mixed with air, and the mixing wheel 14 may be positively driven. The supply of fuel to the nozzle 7 may also be controlled according to engine speed or by a cam associated with the accelerator lever. The Provisional Specification also states that the mixture is passed between a system of plates maintained in oscillation by electromagnetic means and through a chamber in which an electromagnetic field is set up by an induction coil.

Title: Automatic film winding mechanism
IPC: G03B19/04
Filed: 1964-02-10
Abstract: 992,223. Automatic film winding in a photographic camera. EASTMAN KODAK CO. Feb. 10, 1964 [Feb. 11, 1963], No. 5458/64. Heading G2A. An automatic film winding mechanism comprises a metering lever selectively preventing wind-on rotation of a take up spool and sensing selected locations on a film strip, a first resilient means urging the metering lever out of sensing engagement with the film during a first part of the wind-on cycle, and a second resilient means urging the metering lever into sensing engagement with the film during a second part of the wind-on cycle. As shown, a film roller locked on a disc 74 (Fig. 5) is driven by a spring 82 through a shaft 23 and driver 85. The spring also drives gears 90, 91, 51, 52, 50 and 30. The speed of gear 30 and hence of the whole spool drive mechanism is controlled by means of a governor comprising lugs 96 which engages shoes 94 in frictional engagement with a cup 97. The gear 30 can be locked in a stationary position either by pawl 31 or by pawl 36 secured to a plate 41 (Fig. 3). Plate 41 is pivoted at 42 and has a finger 38 which can engage apertures 39 in a film 17 but is urged by a weak spring 43 out of such engagement. The above mechanism is controlled by a plate 46 pivoted by a pin 55 and slot 56 and normally held in an inactive position by a notch 24 on a shutter release 21. When the plate 46 is released by the downward movement of the lever 21 it is driven by a spring 26 so that a lug 45 frees plate 41 which is urged by spring 43 to free the film and move pawl 36 from the gear 52. When the lever 21 is released and moves upwardly a lug 28 thereon frees pawl 31 from pinion 30 and the film spool and pinion 52 are then freed to rotate. Pinion 52 engages a rack on plate 46 and moves it against spring 26, lug 45 passing behind an arm 40 until it engages a lug 67. Pinion 52 then engages a part of the rack at right angles to the first and rotates the plate 46 clockwise (Fig. 2). It is then urged to the right by spring 26 until lug 45 is locked behind arm 40. This situation remains until the finger 38 engages an aperture 39 and allows the rack to complete its movement wherein the foot 25 engages the notch 24.

Patent GB-388570-A (GB)
Title: Process for the production of base-exchanging substances
IPC: C01B33/46
Filed: 1932-02-24
Abstract: Base-exchange substances are obtained from natural or artificial aluminium silicates not readily decomposed by hydrochloric acid by heating the silicates, crushed to the desired grain size, with a fused alkali to a temperature below the melting point of the mixture. Superficial activation of the silicate is thus effected.  The amount of alkali used is sufficient to cover the silicate grains.  When treating silicates not sufficiently resistant to the action of alkalies alone, a neutral salt such as a nitrate, nitrite, borate, or phosphate may be used with the alkali to modify its action.  The products are hydrated and soluble salts removed by washing with water or treatment with steam.  Substances which may be treated include difficultly decomposable substances such as felspars, pyroxenes and amphiboles, pitch stones, clay, shales, glasses, and clinkers; and more readily attackable minerals such as alkali hornblendes and glauconites.  Examples relate to the treatment of coal shale and orthoclase with alkali at 400-500 DEG  C. and 600-700 DEG  C. respectively; and to the treatment of felspar at 400 DEG  C. with alkali to which 10 per cent of borax has been added.

Title: Regulatable pump device
IPC: B60T8/42
Filed: 1975-02-12
Abstract: 1493674 Antiskid braking systems W K H FUCHS 12 Feb 1975 5910/75 Heading F2F [Also in Division F1] A regulatable pump device for increasing the brake fluid volume in an antiskid system to reduce brake pressure comprises a cylinder 57 containing a reciprocating piston 74 dividing the cylinder into first and second chambers 75, 56, a reservoir 73, a check valve 58 between the reservoir and the second chamber, at least one opening 54 between the second chamber and the reservoir, a valve for the opening having a valve element in connection with the piston 74, a slide valve element 55 in communication with the opening and means for adjusting the slide valve element so that the opening can be closed by the means as well as by the piston whereby the effective piston stroke is regulatable. The pump is driven by a motor 59 through a cam 61 and follower roller 63 and the brake system includes a master cylinder 16 connected through a solenoid valve 51 with a chamber 82 having a direct or, as shown, indirect connection with wheel cylinders via a piston 49. Between chamber 46 of the master cylinder and working chamber 76 of the pump 60 is a valve 80 which can be controlled hydraulically as a non-return valve and also by a pin 75 on the piston-rod. The slide valve element 55 is adjusted against a spring 64 by means of a piston 77 open to pressure from chamber 46 via a throttle 79 which damps undesired surges. A sensor 26, determines rotary deceleration of a wheel and when a predetermined limit is exceeded provides signals to operate the motor 59 (to rotate a cam 61) and also to energize valve 51 or a parallel valve 48 so that braking pressure applied by the driver is cut off from chamber 82 and as the pump operates liquid is returned to reservoir 73 to reduce braking pressure, the stroke of the piston thus being determined in accordance with the braking pressure applied by the driver. The signals are applied via a relay 27 operated by the deceleration sensor 26, and via centrifugally operated contacts 50 driven by the pump 59. If at the end of the pump stroke, the sensor still detects skid conditions, a solenoid winding 71 is energized to open a valve 69 to release the brake pressure further.

Title: Improvements in refining hydrocarbon distillates
IPC: C10G50/00
Filed: 1928-02-28
Abstract: 293,440. Gray Processes Corporation, (Assignees of Pease, H.). July 7, 1927, [Convention date]. Mineral and tar oils, purifying.-Hydrocarbon distillates and the like are purified by passing them preferably vaporized through solid adsorptive material such as fullers earth, which is revivified at intervals by increasing the pressure differential therethrough by reducing the pressure applied to the effluent fluid while maintaining that applied to the entering fluid. Hydrocarbons pass through a pipe 12 of a cracking-unit furnace still 10 to a reaction chamber 13 connected by a pipe 14 to a vaporizer 16 and a. dephlegmator or bubble tower 18. Vapours of the desired fraction pass by a pipe 19 to a treating tower 21 containing a fluid-permeable shelf 22 carrying fullers earth and having a spout 24. Vapours may pass by a valve pipe 25 to a condenser 27 and gas separator 29. Unstable unsaturated hydrocarbons polymerize and condense in the earth and pass through a pipe 32 to the lower portion of a tank 33 and thence through a valved pipe 34 and a pump 36 to the towers 16, 18. A liquid level regulator 45 on the tank controls the pump so that vapours do not return to the tower 21. A further pipe 41 with a valve 42 leads the hydrocarbons through a cooler 43 to a tank 44. The vapours are delivered to the vaporizer 16 under super-atmospheric pressure, and, when the earth becomes inactive, the valve 42 is opened so that the pressure differential and vapour flow through the earth are increased, and the effluent gases are under atmospheric pressure while entering pressure is maintained. If gases enter at atmospheric pressure, a partial vacuum is periodically applied to the tank 44. In a modification the pipe 41 leads from the top of the tank 33 so that vapours only pass to the cooler 43. The earth is finally treated as by burning.
