IPC: B23F5/20
Filed: 1920-07-02
Abstract: 166,808. Rogers, F. H., (Benson Gear Co.). July 2, 1920. Gear-cutting,-In a process for cutting worm gears, particularly suitable for gears of the Hindley screw type, two rotary cutters are employed, one of which cuts successive advancing faces on the rotating blank while the other simultaneously cuts successive receding faces. The blank 10 is carried on a vertical spindle and driven by worm gearing from a shaft 15 mounted in a frame 16 and driven by bevel-gearing from a. vertical shaft 17. The driving-shaft 20 carries a. feathered bevel-wheel 21 driving the cutter-shaft 23, which is carried in bearings 24 on a slide 25. Each of the cutters 28, 29 comprises a number of radiallyarranged elements depending on the number of threads on the worm. The cutters 28, 29 operate respectively on the advancing and receding faces of the continuously rotating blank, cutting feed being applied by means of the hand-operated screw 27.

Title: Process for the recovery of elementary sulphur from sulphur dioxide and gases containing same
IPC: C01B17/04
Filed: 1937-07-01
Abstract: 500,041. Reducing sulphur dioxide to sulphur. METALLGES. AKT.-GES. July 1, 1937, No. 18351. Convention date, Aug. 10, 1936. [Class 90] Sulphur is obtained from sulphur dioxide or gases containing it by reduction with coal, coke or other solid carbonaceous material so that the sulphur dioxide is passed in a furnace operated without external heating through a layer of fuel of such a depth that at a given velocity of the gas no free sulphur dioxide is present in the exit gases which are also at a temperature not exceeding 800‹ C. Under these conditions, the ratio COS + CO/CO2 present in the outgoing gases is substantially constant, and the sulphur compounds present are converted catalytically to sulphur in known manner by the addition of further sulphur dioxide. The heat required for the reduction may be supplied by adding air to the sulphur dioxide gases treated, or by preheating e.g. heat exchange with the exit gases, or both. The depth of the fuel bed is considerably more than 35 cm. and is preferably about 50 cm. In the first example, the reduction of pure sulphur dioxide is described and a comparison is made between a fuel bed 35 cm. deep and a fuel bed increased to 50, 90 and 140 cm. Temperatures and composition of outlet gases are given. The second example describes the reduction of a mixture of 50 per cent sulphur dioxide and 50 per cent air. Specifications 339,926, [Class 1 (ii)], 406,343, 435,116, 443,314, and 480,519 are referred to.

[Also in Group XXI] A flow-control apparatus, particularly for the well-head system of a flowing oil well, comprises a safety shut-off valve 10 of the sliding gate-type on the upstream side of a pressurereducing choke 50 in a high-pressure flow line 44, 51, this valve having a gate, Fig. 1, comprising two closure plates 20, 21 which are spring-urged against their seats and together define an upper flow port 24 and a lower blind 23, the valve being adapted to rise automatically from an open to a closed position, by pressure of fluid leaking past the upstream plate 20 and acting on the area of a stem 17, when a control fluid pressure applied above a piston 27 falls sufficiently, the space above this piston normally being pressurized from a point downstream of the choke so that the valve is held open and closes if there is a substantial loss of pressure in the flow line downstream of the choke. In an oil well-head system, Fig. 2, the space above the piston 27 communicates through a normally open line valve 37 with the bottom of a gas-oil container 47 which is pressurized from a point 48 in the flow line through a normally open line valve 38. Pressure in the container can be relieved to atmosphere through a stop valve 45. The system includes an alternative pressure source 49 of nitrogen for pressurizing the container through a valve 36; and a hand pump 41 for applying oil pressure direct to the piston 27 from the container through suction and delivery line valves 39, 40 respectively.

A diffuser for use in a compression system for gaseous fluids comprises coaxial inner and outer circular section walls and a substantially annular hollow splitter structure supported by the outer wall and having annularly distributed gas inlets at its upstream side and an outlet connected to the exterior of the outer wall. The invention is described with reference to a gas turbine engine which comprises an axial-flow compressor indicated at 10, 11, diffuser section 12, a combustion section 15 and a turbine indicated at 20. The diffuser section comprises inner and outer divergent walls 13, 14 which are interconnected by equally-spaced hollow vanes 21, a number of the vanes being formed with openings 22 in the side walls. Flange members 25 (Fig. 2 not shown) are secured by bolts 26 to the lands 23 around the openings 22 and segmental pieces 24 of a hollow ring-shaped splitter are secured to the flanges 25 of adjacent vanes. The segmental pieces each comprise sheet metal inner and outer walls 28, 29 which are open at the upstream end to form a bleed air inlet 27, and are connected together by a rear wall 35. One of the vanes 21 is connected to an outlet duct 50 whereby air bled off through the inlets 27 may be passed to a point of use. Some of the flange members 25 are formed with lugs 31 Fig. 4 not shown which co-operate with the flame tube walls so as to support the latter. The combustion equipment comprises an annular flame tube 18 the outer wall of which is built up of ring sections 36, 37, 38, 39, 40 which are spaced apart by corrugated spacers 41 and the inner wall of which is built up of ring sections 42, 43, 44, 45, 46 which are spaced apart by corrugated spacers 47.

[Class 4] [Also in Group XXVI] In an aircraft gas turbine fitted with a jet pipe having a nozzle end 14 for efflux of the working fluid, jet spoiling means associated with the nozzle end comprises at least one pair of pivotable jaw members having a crosssectional shape presenting a hollow body conforming to that of the nozzle end and, when they are in the non-spoiling position being disposed co-axially therewith to provide a wholly unimpeded flow path for the working fluid, but being movable to a jet-spoiling position where they form a baffle across but spaced from the nozzle end. The jaws 10, 11, Fig. 3, are pivoted to radius rods 22, 23 and operated by a push-pull rod 15 secured to. adjacent corners 45, 46. Forward movement of the rod sets the jaws across the end 14 of the nozzle and cowls 18, 19 on them give a reverse component to the jet. In another form the jaws are pivoted at 45, 46 and the radius links are connected to the push-pull rod, the cowls 18, 19 being omitted. As shown in Fig. 5, the jaws 20, 21 pivot about a single pin 20a and in their open position form part of the nacelle 38 as do extension flaps 29 pivoted to the jaws at 29a and secured to operating rods 27. These rods are connected to a nut 30 on a screwed rod 31 adapted to be rotated through a sprocket 32 by a chain encircling the jet pipe 14a and driven by an electric motor. Rearward displacement of the rod 27 turns the jaws to the spoiling position and disposes the flaps 29, to reverse the jet, as shown in the heavy chain lines. The jaws may form a continuation of the jet pipe and be provided with outer shields continuing the nacelle, the air flow induced between the nacelle and the jet pipe serving to cool the pipe and being deflected outwards by a flange on the end of the jet pipe. Alternatively the jaws, arranged to form a continuation of the jet pipe, taper rearwardly and so give some reverse thrust when in the jet-spoiling position.
