Abstract: 1,157,241. Winding or reeling rod or wire. SCHLOEMANN A.G. 17 Feb., 1967 [17 Feb., 1966], No. 7754/67. Heading B3E. Apparatus for winding or reeling rod or wire includes a laying member rotating about a horizontal axis to form vertical loops of rod or wire and means for tilting the loops over so that they can be carried by a conveyer in an open form or fall directly into a collector. Vertical coils formed by a rotating laying pipe 2 are tilted over on to a slow ribbed conveyer 6 by a fast ribbed roller 8, Fig. 1, engaging the upper parts of the coils. The coils may be tilted, instead of by the roller 8, by engagement of their lower parts with a tripping edge, Fig. 3 (not shown), as they engage the conveyer. In another arrangement, Fig. 4 (not shown), the coils are guided from the laying pipe 2 in a downwardly curved casing to fall on to the conveyer 6, the coils being cooled in their descent by air from manifolds in the sides of the casing. In another arrangement, Fig. 6, coils from a rotary pipe 16 and helical guide 18 pass over a braking roller 20 having hooks 21 engaging the lower parts of the coils which then fall on to a belt 22 to pass to a collector 23. In a further arrangement, Fig. 7. coils from the rotary pipe 16 and helical guide 18 are conveyed down an elliptical sectional tube by a ribbed belt 24 to fall into a collector 23.

Abstract: 686,749. Burners. LUMMUS CO. March 25, 1949, No. 8185/49. Class 75(i) [Also in Group XII] A burner for gaseous, liquid, or solid fuel comprises a tuyere 10, Fig. 1, through elongated openings 20 between the generally tangential blades 18 of which air, supplied under low pressure to a casing 11, passes to form a hollow vortex which entrains fuel supplied through the lower ends of the openings 20 from a surrounding pan 12. The latter is either fed by gravity from a liquid fuel tank 15, or. with gaseous fuel by a blower, or with pulverulent fuel by a screw conveyer. The swirling fuelair mixture passes into a furnace through an opening in a refractory wall 28, said opening having a paraboloidal wall surface 29. Fig. 3 shows a burner mounted in the side wall of a furnace, primary air being supplied through a duct 34 to a horizontal tuyere 32 having a fuel-feeding member 33 supplied through pipes 60, 61, and 39 with either gaseous or liquid fuel or a mixture thereof. To ensure even distribution of the air passing into the tuyere 32 the latter is provided with two banks of blades 32a, 32b, and a cylindrical skirt 54 divides the airflow at the junction of the blades. The primary air passes also through apertures in an annular plate 32a at the end of the duct 34. Secondary air, controlled by a rotary hit-and-miss device 50, 51 in a windbox 35, is passed into the ,combustion chamber through apertures 46a in a refractory block 46. In Fig. 7 is shown a boiler incorporating a tuyere 86 supplied with fuel and air through a pipe 87 and a conduit 88. Combustion takes place in a refractory throat 90 and the combustion products pass to a stack 78 through a chamber.74 and tubes 76 within a water drum 72, thus heating the water to produce steam in a dome 81.

Abstract: 589,766. Control of two induction motors. TOWLE, E. L. N., WALSH, A., LAST, C. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 3, 1945, No. 8199. Drawings to Specification. [Class 38 (iii)] A hoist or the like operating in opposite directions on relatively heavy and light loads respectively, e.g., an excavator of which the shovel is raised loaded and lowered empty, employs two direct coupled polyphase induction motors arranged, for the lowering operation, for one motor to give a driving torque of determinate value at standstill which may decrease as the speed increases and the other to give a braking torque increasing with speed, the combined torques reaching zero at a low speed. The first machine may be a small auxiliary motor, normally connected, and the main machine may have single-phase excitation giving a zero torque at standstill increasing in proportion to speed, the combined torques being zero at 20-25 per cent. full speed. The rotor circuit of this auxiliary motor would have high resistance; this motor may assist the main motor when hoisting. The controller may vary the rotor resistance of either or both machines to give different speed-torque characteristics. Alternatively two identical polyphase induction motors may be used one giving a driving torque for lowering which may fall with increase of speed and the other a braking torque which may rise with speed and the primary windings may be paralleled for equal load sharing when hoisting.

[Also in Groups XII and XIII] An air heater for a motor vehicle comprises an annular combustion chamber 8 supplied with a mixture of liquid fuel and air by a positive displacement pump 4. The mixture is delivered to the combustion chamber by a pipe 5 which directs the mixture against the inner wall of the combustion chamber. The mixture is ignited by an igniter 7 and the combustion gases pass along a straight exhaust pipe 9. The air to be heated is driven by a blower 3 into an annular channel 12 surrounding the exhaust pipe 9 and passes to an outlet 13 connected to a space to be heated. The annular channel 12 is spaced from the exhaust pipe 9 by channels 14, 15 formed between walls 16, 17. Gas leaking from the exhaust pipe 9 enters the channels 14, 15. The air for mixing with the fuel is sucked by the pump 4 along a pipe 19 connected to a cup 22 surrounding the combustion chamber. The fuel is sucked from a supply vessel 37 and enters the air stream through an injector 26 disposed in the air pipe 19. The suction on the fuel moves a diaphragm 38 in the supply vessel 37 upwardly to open a spring-closed valve 39 and fuel flows into the supply vessel 37 from a storage vessel 29 having one wall formed by an elastic diaphragm 33. Fuel is pumped into the storage vessel 29 by the pump which also supplies the carburetter of the vehicle.

[Class 135] A multiple-way valve device particularly adapted for use in connection with diffusers used in sugar factories comprises a hollow rotary plug adapted to couple successively adjacent radial passages of a series while at the same time connecting one of the free radial passages to an axial passage. In the form shown a casing with four radial passages 2, 3, 4, 5, and an axial passage 6 houses a hollow tapered plug 9. This plug has two internal walls 10, 11, forming between them a passage opening on the conical surface of the plug. The remaining internal space of the plug has a port 16 on the conical face and axial ports 16 in the smaller end of the plug. The plug is turned by a spindle 19 provided with a hand lever 20 fitted with a spring pressed locking catch adapted to engage notches in a plate 46. To ease the plug from its seat a sleeve 23 encircling the spindle 19 engages a threaded aperture in a bridge 18 and when rotated by a handle 29 on a tubular member 28 moves into engagement with a collar 21 secured to the spindle 19 to force the plug out of its seat. The outlet from the axial passage is controlled by an independently actuated lift valve 32. The spindle of this valve is coupled by a lever 35 with a spring-loaded rod provided at its upper and with an operating handle arranged in proximity to the hand lever 20. The means for actuating the valve 32 may comprise any system of rods, links or bars or a transmission including toothed wheels, chains &c. Specification 28197/97, [Class 135], is referred to.
