Title: Apparatus for the mechanical control of the ascension pipe valves in coke ovens of the chamber type for the generation of coke and gas
IPC: C10B27/06
Filed: 1950-08-04
Abstract: 693,228. Ascension pipes. KOPPERS GES., H. Aug. 4, 1950 [Aug. 5, 1949; July 22, 1950], No 19618/50. Class 55(ii) [Also in Groups XXIV and XXIX] Apparatus for controlling the operation of the throttling members in the ascension pipes 11, Fig. 1, of chambertype coke oven batteries to control the gas pressure in the chambers 10 comprises a snail cam 5 for each chamber rotated at a controlled rate through a free-wheel device and acting, via a push rod 6, on a hinged valve in the ascension pipe leading from the chamber to a collecting main 12. In one arrangement, each cam 5 is rotated at a uniform speed by a shaft 3 and progressively closes its hinged throttle valve member 14, Fig. 2, throughout the coking operation, through the push rod 6 connected to the member by a link 30. Each cam is rotatable on the shaft and is driven through a free-wheel device in the form of a ratchet wheel 27, Fig. 3, on the shaft engaging a pawl 28 on the cam. Each cam is rotatable manually by a chain 23 and each valve member is movable to closed position by a rod 32 independently of the cam. The drive connection between the shaft and cam may be disconnected by rotating a sprocket 34 with a chain 33, the sprocket having a cam part 34<SP>1</SP> which raises a lever 36 fixed to the axle 37 of pawl 28. The push rod 6, as it approaches the highest part of the cam, moves a bell crank carried on the cam to raise the pawl 28 and disconnect the drive and hold the valve member stationary. In another arrangement, the cams are rotated through free-wheel devices 43, Fig. 6, and connecting links 45 by a transversely oscillating rod 47. This rod is connected by a flexible link 52 with another rod 53 and both are pivoted to a plate 49 pivoted at 55. The plate is turned in alternate directions by a rod 57 oscillated by a motor device 58, e.g. a piston and cylinder device which provides a much slower movement in the direction to cause rotation of the cams, than in the return direction. In yet another arrangement, a chain driven by a constant speed electric motor drives the cams through sprockets, and free-wheel devices.

Filed: 1944-10-17
Abstract: 584,339. Gear-cutting. McLEOD, R. J. Oct. 17, 1944, No. 20070. [Class 83 (iii)] An attachment to a gear hobbing, shaping or planing machine to enable a roughed out gear to be finished by a shaving intermeshing generator cutter at the same setting comprises a base 1 for attachment to the machine 1a in place of the roughing cutter and carrying bearings for the finishing cutter 11. The latter has involute teeth conjugate to' those of the work and provided with cutting edges on the flanks, and the helical angle of the teeth may be the same as that on the work or different. The cutter is mounted on a freely running spindle 10 supported in journal bearings 7, 8 on a head 3 which is angularly adjustable on a slide 2 movable on guides 5 on the base 1. Axial movement of the spindle 10 in the head is prevented by a double thrust bearing 9. After feeding the cutter 11 into full mesh with the work, the latter is rotated and the cutter is fed along the work axis at a speed of from 0.0005 to 0.01 inch per revolution of the work to traverse the whole length of the teeth on the work. During this traverse the cutter and head 2 are reciprocated with an amplitude equal to or slightly more or less than the axial feed by means of a shaft 4 journalled at 12, 13 in the base 1 and having an eccentric portion 14 carrying an eccentric sleeve 15. The sleeve is rotatably adjustable on the shaft 4 through a serrated coupling 17 keyed to the shaft and locked by a nut 18,so that the eccentricity of the sleeve relatively to the axis of the shaft may be varied from zero to a maximum equal to the sum of the two eccentricities. The sleeve engages a block 19 stidable between horns 20 on the slide 2 so that the latter will be reciprocated when the shaft 4 is rotated by the cutter drive of the machine or by a separate motor. Alternatively the cutter may be reciprocated by an adjustable throw crank. The axis of spindle 10 may be set parallel to the axis of the work or in a crossed axis relation thereto, a graduated angular scale on the head 3 facilitating the setting, and the helical angle of the teeth on the cutter 11 may be equal to or less than that of-the teeth on the work. The direction of reciprocation of the cutter may be parallel to the teeth on the work or may be inclined at 15 to 20 degrees thereto by swivelling the hob saddle of the gear cutting machine on which the base 1 is mounted.

Title: Improved method and apparatus for treating textile materials with circulating liquors
IPC: D06B5/00
Filed: 1932-07-18
Abstract: <PICT:0404370/IV/1> The circulation of liquid in a kier 1 for treating textile materials with liquids is automatically controlled so that when the level of the liquid in the well 5 of the kier falls below a predetermined point, the supply of steam or other circulating means is cut off, or the actuating means is shut off from the circulating pump.  In its simplest form the invention consists in a single float valve placed directly in the well underneath the false bottom of the kier.  It is preferred to place the valve 21 outside the kier but in liquid connection therewith.  The valve 21 controlls an electrical switch 24 and if the float of the valve sinks too low the switch is opened and the motor 10 driving the pump 9 is stopped. The valve may also be actuated by the level of the liquid 20 above the materials, the motor being stopped if too much liquid collects above the materials, or two control devices may be provided, one actuated by the liquid 20 and the other by the level of the liquid 4. It may be arranged that liquid to the sprinkler 18 is cut off while liquid is still forced through a perforated upright pipe in the kier. More than one upright pipes, separately controlled, may also be provided.
