Title: Apparatus for the production of fuel
IPC: C10L1/32
Filed: 1920-12-09
Abstract: 155,209. Bates, L. W. Dec. 10, 1919, [Convention date]. Liquid fuel. - In making fuel consisting of solid carbonaceous particles stabilized in a liquid combustible, the coal, coke, lignite, &c. crushed between rolls 11 is lifted by a bucket conveyer 18 to a hopper 19 and, in quantities regulated by a valve in the outlet pipe is fed by a conveyer 22 to a mixer 26 to which the oil from a reservoir 27 and if desired peptizing or other stabilizing agent from a preferably steamjacketed tank 34 are admitted by pipes 28, 35. The mixture flows to a ball mill 39, and after being blended is discharged to a separating tank 40, to trap any coarse particles, and is forced by a pump 43 to a reservoir 46 preferably containing a heating coil 47. The outlet of the ball mill is preferably provided with a ribbed and ridged liner 51 to agitate the outflowing mixture and prevent the passage of coarse particles. An agitator and a heating coil may be arranged in the reservoir 46. The stabilizing agent may be a limeresin or other soap as described in Specification 165,418, creosote, water-gas tar, a liquid hydrocarbon immiscible with the liquid combustible, or alkali to combine with acid constituents of the oil or coal. A modified form of apparatus is also described in which the coal crushed by the rolls 11 falls into a ball mill, and is passed out through a fine screen to a mixer such as 26; the mixture is then passed through a second mill and discharged to a collecting tank. Stabilizing agents may be added to the coal, the oil, or to both. According to the Specification as open to inspection under Sect. 91 (3) (a) gas having peptizing action may be used to stabilize the suspension. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to mixture supply systems of internal combustion engines
IPC: F02M7/20
Filed: 1927-12-23
Abstract: 305,338. Beatson, F. H. P. Dec. 23, 1927. Spray-carburettors.-Temporary enrichment of the normal mixture is produced during opening of the throttle from or to any position, the enrichment being maintained during a period of acceleration; temporary weakening is produced during closure of the throttle from or to any position, the weakening being maintained during a period of retardation, and complete cessation of fuel flow occurs during a period of extreme retardation. A nozzle c fed from a float chamber b discharges fuel at the throat e of the suction passage a provided with a throttle valve d. The fuel flow is controlled by a valve f the spindle l of which is connected to a diaphragm or piston m forming a partition between chambers i, k. These chambers are connected by branch conduits h<1>, h<2> respectively and a conduit h to the throat e of the suction passage and a constricted orifice x is placed in the branch h'. The diaphragm is under the control of opposed springs n, o; its upward movement is limited by a resilient stop p, and its downward movement by a stop g<4> below the fuel valve. With any condition of running the diaphragm m will assume a position of equilibrium with a certain suction valve at the throat e. If, now, the throttle valve d be opened to accelerate, the suction at c increases. This increased suction is transmitted instantly to chamber k but only after a time lag, depending on the constriction x, to chamber i. The result is that the diaphragm is moved to open the fuel valve f and enrich the mixture, and this increased opening persists until equal pressures are established in the chambers i, k. Conversely a closing of the fuel valve takes place when the throttle valve is moved in the closing direction, but the stop p provides for a minimum flow which may vanish entirely if the retardation be extreme. At very large throttle openings air may be admitted to the chamber i to force the fuel valve against the stop g<4>. To .effect this the spindle q of the throttle valve has a cross passage r which, when the throttle is fully open, connects apertures s, t in the spindle bearing to form an air inlet to a conduit u which delivers to chamber i. In a modification, the valve f is replaced by a valve which controls the inlet to an air tube which surrounds and terminates approximately at the outlet of the fuel nozzle. The stem l may actuate a valve for controlling air direct to the nozzle c or to the float chamber.

Title: Improvements relating to dye vats
IPC: D06B23/00
Filed: 1930-11-25
Abstract: <PICT:0367838/IV/1> <PICT:0367838/IV/2> In dyeing goods such as gloves, hat bodies, and stockings by causing a current of liquor to pass through the goods and to hold them against a perforated plate, the current is reversed from time to time, whereby the goods are lifted from the plate, turned over, and brought against another part of the plate or against another plate.  In the arrangement illustrated in Fig. 1, the dye-vat 1 has a perforated base 2 and a chamber 3 for guiding the current. A partition wall 4 divides the base 2 and chamber 3 into equal parts.  The sections 5, 6 of the chamber 3 are connected by a compartment 7 in the centre of which a propeller 8 rotates in an opening of the wall 4.  The steam worms 9, 10 may be controlled by valves, or by a three-way cock.  At one end of the propeller shaft is a gear-box 13 with automatic reversing apparatus, and the valves are moved when the direction of flow is reversed.  In operation, dry articles are preferably damped by being laid on a grating, and the charged vat may be closed by a cover. When the propeller is rotated, the liquid is forced from below through one side of the base, whereby the goods on this side are raised, and the change of direction of the current in the vat from vertical upwards to horizontal and then to vertical downwards effects a complete change over of the goods, which are then pressed like a filter on the other side of the base.  After a suitable interval, the rotation of the propeller is reversed, whereby the current of liquid is also reversed, and the hat bodies are raised, turned over and deposited as before.  The steam valves are reversed after the propeller, so that no uncondensed steam comes into contact with the goods under treatment.  With the angular base 18 shown in Fig. 4, the action is similar, but during the reversal of the current the surface supporting the goods is brought into the vertical position, whereby the movement of the goods is facilitated.
