Filed: 1948-09-15
Abstract: 653,289. Combustion systems using pulverulent fuel. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Sept. 15, 1948, No. 24209. '[Class 51 (i) ] In a combustion chamber in which pulverulent fuel is burned, the fuel delivered by a screw conveyer 16 is entrained at 10 by air which has been heated in passing through a jacket 5 around the combustion chamber. The air and fuel pass through a volute 13 to a chamber 14 and enter the chamber 1 tangentially at its periphery. The fuel burns in the whirling mass of air and the products of combustion emerge through the central opening 8. Other air is led to the chamber tangentially through a conduit 22. Some air with the lighter fuel particles passes from the chamber 14 into a chamber 21 and thence is led to join the air in the e conduit 22. Air from the jacket 5 passes through a volute 7 into a convergent conduit 9 such that the static pressure of the air stream is sub-atmospheric at the entraining point 10. Specifications 338,108. [Class 51(i)], 639,468 and 639,483 are referred to.

Filed: 1950-10-04
Abstract: 668,813. Beet harvesters. JONGENEEL, A. M. Oct. 4, 1950. No. 24264/50. Class 6(iii). A tractor-mounted beet-harvester comprises an assembly extending along one side of the tractor and consisting of a main frame 12 mounted on the back axle housing 8 of the tractor and floatingly supporting a sub-frame 21 carrying a spiked pick-up. wheel 29 and topping apparatus 47. The main frame is rectangular and comprises side-beams 13 joined by front and rear members 14, 15. The rear member 15 is integral with arms 16 secured to a crossshaft 11 journalled in brackets 9 on the axle casing 8. The front member is supported by a hydraulic jack 20 on the tractor chassis 2. The sub-frame 21 comprises side-beams 22 supporting the pickup wheel and secured to a crossshaft 24 at the rear. The crossshaft 24 is carried by bearings journalled on the tractor axle 6 and is connected to the main frame by a spring-loaded device 40 which permits resilient floating movement between the frames 12 and 21 but ensures the sub-frame being raised by the jack 20. The main frame carries twin-shares 34, and coulters 38 for cutting excess foliage. The beets are raised on the spikes 31 of the wheel 29 and are topped by the device 47 which comprises an idle cutting wheel co-acting with a driven cutter 50. An arm 58 rotating with the cutter 50 sweeps the topped beets into a lateral conveyer 54 which delivers them rearwardly to an elevator 62 discharging on to a truck alongside. The tops are retained on the spikes 31 from which they are stripped by a series of bars 65 to fall on to a transverse conveyer 68 for discharge on to the ground. The pick-up wheel, the topping-knife and the various conveyers are driven from the tractor axle 6 by belt and chain gearing.

Abstract: 243,762. Alexander, J. E. Nov. 28, 1924, [Convention date]. Drying fabrics and materials in long lengths.- A method of drying material such as paper consists in the application of radiant heat in a chamber from which air is removed by the higher pressure of the gaseous medium removed from the material within the chamber, the percentage of moisture remaining in the material at the end of the drying operation being controlled. A web 2 of the material to be dried, such as paper, is fed into a housing 1 and threaded through the drier on Fourdrinier wires 4 supported on breast rolls 6 and 7 at each end and by rollers 8 at intermediate points. To allow for expansion and contraction, the rolls 7 are mounted in carriages 21 running on rails 19, weighted cables 23 being secured to the carriages and holding the wires in tension. The interior is divided by baffle plates which extend transversely between the passes of the drier. The web is passed in and withdrawn through sliding door members 32, 33 positioned to allow narrow openings. The drying is effected by a series of electric heating elements 34 beneath each path of the wires 4, these elements being adjustable by links 38 and cranks 39 whareby the heating effect is controlled. The breast rolls bearings are water-cooled, pipes 44 carrying the water from one bearing to the next. The steam generated displaces the air from the chamber 1.

Filed: 1956-08-09
Abstract: 834,026. Mixing fluids in flow. CHIANTELASSA, A. Aug. 9, 1956 [April 12, 1956], No. 24433/56. Class 86 An apparatus for dispensing a mixture of two liquids under pressure, such as a basic liquid, petrol and an additive, oil, comprises three meters 1, 2, 3 two of which are of equal size but with adjustable outputs inversely related to each other and arranged to deliver petrol and oil respectively, and the third meter for petrol of a larger capacity which is synchronized with the two smaller meters so that the total output of the apparatus is constant. The three meters each have five rotatable cylinders 5 with associated pistons 6 and rods 7 passing through a perforated plate 9 fixed to a rotatable shaft 8 or 17, the whole rotating about a common axis H, H. The shaft 17 of the other two pumps 2, 3 are geared to the shaft 8 by bevel gears 16, 16<SP>1</SP> which also acts upon a rotary shaft 8<SP>1</SP> for the attachment of an indicator to show the total quantity of liquid delivered. During rotation the cylinders 5 alternately pass in front of inlet and outlet ports 10, 11 respectively the capacity of the pump being determined by the angle of inclination of a plate 13 which is mounted in a bearing 14 located within a member 15 fixed to the meter housing and against which terminal balls 12 on the piston rods 7 act. The outputs of the two small meters are regulated in an inverse proportion to each other by a link 20 and two levers 18 and 19 (Fig. 3) which latter alter the inclination of the two inclined plates so that the strokes of the pistons may be varied but so that the total output of the two pumps is constant. The relative outputs of the large meter to the two smaller meters may be controlled by altering the angles of the inclined plates.

Abstract: 501,215. Scraping sludge &c. from tanks. HARTLEY, E. Sept. 11, 1937, No. 24802. [Class 78 (iv)] [Also in Group I] Scraping mechanism for removing sludge or other deposit from tanks and the like, is carried by a travelling gantry which is propelled over the tank by pairs of ropes anchored respectively to opposite ends of the tank and fixed to a common winding drum on the gantry so that rotation of the drum causes one to wind on and the other to be paid out simultaneously. In the form shown in plan in the Figure, the scraping element 27 is carried by a trolley which can be traversed by hand or power across the gantry 25 to serve any one of the three tanks 10. The gantry carries a motor 17 driving a shaft 18 on which the spirally-grooved winding drums 19 are mounted. The ropes 21 connected to the drums 19, are anchored at 23 to screw-adjusted tensioning members, and traverse the gantry along the tanks to haul the scrapers whenever the drums are rotated in one direction or the other. Winding-drums 39 on the trolley raise and lower the scrapers as described. Twin winding-ropes 21 may be used for safety; the drums being formed with double-threaded spirals for this purpose. Breaking of a rope may cause a pulley or other rope-supported member to drop and actuate cut-out mechanism to stop the motor. The trollies also carry depending scummers that can be raised and lowered at will. Specifications 333,903, [Class 78 (i)], and 353,029, [Group XXIX], are referred to.
