Title: Improved method of truing gear cutters
Inventor: HARTMAN HERBERT GEORGE
IPC: B24B3/02
Filed: 1954-12-14
Abstract: 759,243. Milling - cutters. GLEASON WORKS. Dec. 14, 1954, No. 36212/54. Class 83 (3). [Also in Group XXIII] The blades 27, Fig. 6, of a multi-bladed face - gear cutter or tapered hob for generating spiral bevel, hypoid or other gears are sharpened by grinding, or otherwise cutting back, their front faces 38, and then trued by an operation which produces narrow lands 41 of very small width L rearwardly of the side cutting edges 28 of the blades. The cutting edges are thus set back radially to an inappreciable extent because the side relief angle C is only 3 to 4 degrees. The trueing operation (see Group XXIII) is effected by using the sharpened cutter first to cut at least one cutting cycle on a gear blank and then allowing the cutter to contact this gear, preferably with reverse rotation and with the use of an abrasive, for abrasion thereby. The cutter blades may be radially adjustable.

Filed: 1933-12-30
Abstract: 416,232. Roughening shoe soles. COMPO SHOE MACHINERY CORPORATION, 565, 5th Avenue, New York, U.S.A. Dec. 30, 1933, No. 36741. Convention date, June 29. [Class 83 (iii).] In a machine for roughening shoe soles the sole 61 is fed continuously past a rotary roughing-tool at a predetermined speed. A pulley 11 which may be driven from an electric motor (not shown) is connected to a pulley 12 on a spindle 13 carrying the tool 20 which comprises a number of roughing needles 21. The spindle is supported in a sleeve 15 which is screwed in to the casing 14 to provide axial spindle adjustment. Ball bearings are provided at 17, 18. The part 22 of the frame has threaded bores which receive adjustable sleeves 25, 34 respectively. The sleeve 25 encloses a slidable plunger 26 urged upwardly by an adjustable spring 33, the upward movement being limited by a cross pin 30 engaging under the sleeve. The plunger carries an axle fitted with a loose cylindrical wheel 29 adapted to engage beneath the work. The sleeve 34 is similarly fitted with a plunger carrying a frusto-conical wheel 39, which may fit against a bevelled edge 62 of the work. The pressure of the wheel 39 may be relieved by means of a rod 44 connected to a treadle. The work-supporting table 46 is resiliently mounted on springs 47<1> fitting around a number of posts 47, slidable in bores in the frame and screwed to receive adjusting nuts 47<11>. The rollers 29, 39 project through an aperture in the work table. A roller 49 serves as an edge guide for the work. A guide 50 is adjustably clamped to the frame by a stud 51 to control the depth of cut. The arm 53 of the frame is preferably hollow and is connected to a suction device for removing dust &c. from the working point. In order to feed the work automatically at a predetermined speed a worm 54 on the spindle is connected through gear 55, shaft 56, and gearing 57-59 to a roughened feed-roller 60 engaging the top surface of the work. In operation, the work is inserted and the needle guard adjusted to rest lightly thereon and the spindle 13 set to give the desired depth of scoring. The springs 33, 43 are adjusted so that the sole is pressed upwards against the feed wheel. While an unbevelled edge of the work such as the fore part is being traversed the roller 39 may yield, the spring pressure on this roller being if necessary relieved by the treadle mechanism. In a modification the tool spindle may be spring pressed against the work. In this case the feed wheel is preferably driven by an independent gear train from the pulley 11. In another modification the roller 39 may be replaced by a stationary support 39<1>, Fig. 4, having four supporting arms 69-72 each arm being provided with a bevelled work-engaging surface of different slope. Any one of the arms may be positioned to engage under the work according to the skived angle thereon.

Abstract: 1,071,355. Percussive drills. WESTINGHOUSE AIR BRAKE CO. Sept. 15, 1964, No. 37599/64. Heading B4C. [Also in Division B3] An hydraulic percussive device such as a rook drill, comprises an impact piston 53 adapted to move, in a housing 22, a striker 45 against the loading of a spring 50, a valve piston 56A for controlling the flow of hydraulic fluid and an accumulator (70, Fig. 4) communicating with the hydraulic circuit and the impact piston and adapted to maintain fluid pressure simultaneously on the control valve piston and the impact piston to thereby offset variations in fluid pressure during operation of the device. The impact piston 53 is provided with a groove 54 for providing communication between passage 88, 89 and 93, 98 formed in the housing 52. The striker 45 is arranged to strike a holder 64 of a tool bit 23, the holder being provided with splines 68A for engagement with a gear 68 which may be rotated, via a gear (67, Fig. 4) by an hydraulically-operated motor 62.

When fluid pressure is fed to the cylinders the housing 22 is raised so as to apply pressure to the tool bit 23. The hydraulic circuit includes a main-operating valve having " neutral ", " impact ", " rotary " and " rotaryimpact " positions. When the valve is moved to the " impact " position, fluid is fed via a valve 85, Fig. 8, to one side 72 of the accumulator 70 and via passages 88, 89, groove 54 and passage 93 to act on a piston 94 secured to the valve piston 56A thereby maintaining it in the position shown. Fluid then flows via passages 74, 75, a groove 76 in the piston 56A and a chamber 71 thereby moving the impact piston together with the striker. to effect a working stroke. At the end of the stroke, the groove 54 communicates the passage 93 with the fluid reservoir and thereby allows the valve piston 56A to be moved to its other position by fluid acting on a piston 96 so that the chamber 71 is exhausted and the striker and impact piston return under the action of the spring 50; in a modification, the piston 96 may be replaced by a spring. By selecting the desired position of the main-operating valve, the various modes of operation indicated above may be obtained. The device may be used as a bolt-tightener in which case a unit (170, Fig. 16) is mounted on the housing 22, a gear spindle 172 being adapted to engage, via a coupling member (171) with the tool-bit socket (65, Fig. 4) in the holder 64. The gear (172) rotates via gears (173, 174 and 176), a bolt-engaging unit (178) which is snapfitted into the gear-member (176). When the bolt-tightening device is in use the mainoperating valve is set in the " rotary " position.

Title: Improvements in or relating to the recovery of sulphur from hydrogen sulphide-containing gases
Inventor: MARSH JOHN DAVID FRANCIS
IPC: C01B17/04
Filed: 1956-12-13
Abstract: Sulphur is recovered from gases containing H2S and at least 3 vol. per cent of HCN and/or NH3 by burning the gases with insufficient air to oxidize all the H2S to SO2, contacting the combustion products with a catalyst material containing as catalyst a refractory non-siliceous oxide or mixture of such oxides at above 800 DEG  C. to reduce the content of HCN and/or NH3 to negligible proportions, cooling the gases, subjecting them to further catalytic treatment to convert the sulphur compounds to elemental sulphur, and separating the sulphur.  The gases may be an H2S concentrate from wet purification of fuel gases containing up to 20% HCN and small amounts of NH3.  The refractory oxides may be MgO, CaO, Al2O3, Fe2O3, Cr2O3, TiO2, or CaO or Cr2O3 on MgO, as tablets, spheres, irregular, or shaped, pieces, or checker brickwork packing.  A small proportion of siliceous binder may be used with the oxide.  For the combustion the air may be preheated, and the H2S gases and air may be premixed in a Venturi tube before passage into the burner consisting of a refractory-lined throat, followed by a conical section of increasing diameter, and a cylindrical section.  Contact with the refractory oxide may be effected at 900-1100 DEG  C. at throughputs 100-500 v/v/hr.  The S may be collected in a condenser and a S condenser may be inserted before each further catalytic stage operated at between 450 DEG  C. and the S dew point with known catalysts.  Where a S condenser is inserted before the catalytic stages the gases are reheated by burning some of the original H2S gases in a minor burner where the method of destroying HCN and/or NH3 according to the invention may also be used.  Specification 686,469 is referred to.
