Title: Process and apparatus for the Wet Treatment of Textile Webs
IPC: D06B15/02
Filed: 1967-04-03
Abstract: 1,175,732. Textile treating apparatus. ARTOS DR. ING. MEIER-WINDHORST K.G. 3 April, 1967 [14 April, 1966], No. 15115/67. Heading D1L. A process for the wet-treatment of moving textile webs is divided into several zones in which the web moves through treatment liquor in flow, and is characterised in that downstream of each zone, liquor is removed from the web in two stages, in the first of which surface liquor is removed by squeezing and returned to the zone, and in the second of which liquor contained in the web is squeezed out and returned to the liquor flow at points of the same or similar concentration. There are preferably at least five zones with at least eight liquor separations. The concentration of the liquor squeezed out in the second stage is used to measure the concentration of the liquor remaining in the material and to adjust the treatment process accordingly. Apparatus for the wet treatment of moving webs includes several treatment zones each including first and second means for removal of liquor from the web downstream of the zone and adapted respectively to squeeze off surface liquor and to squeeze out contained liquor, means for returning liquor from the first means to the zone immediately preceding in the direction of web movement, the second squeezing means being a horizontal doubleroller 13, and means for returning liquor from the second means to the flow of liquor at points of similar concentration. In a preferred embodiment, one roller of the horizontal double-roller 13, in conjunction with a lighter primary roller 14, forms the first squeezing means.

IPC: B23K31/02
Filed: 1916-10-26
Abstract: 110,214. Wolfe, H. L. T. Oct. 26, 1916. Cased or compound forms; boring and drilling drills and cutters; saws; tools.-In electrically welding the ends of band saws or pieces of highspeed to ordinary steel, drills, and cutters for lathes, planing machines &c., the interfitting parts are first caulked to exclude air. For instance, a piece of high-speed steel b is inserted in a slot in a body a of ordinary steel with its end or ends protruding. The edges of the slot are then caulked and current and pressure applied by contacts c to the piece b which is thereby upset at d. The current is then increased while maintaining the pressure to heat the body a as well as the piece b and complete the weld. The piece b may be first plated with copper or other metal to improve the weld. The excess metal e is removed by grinding or otherwise. In joining a band saw., the lapped or butted ends are welded as above into a block which is finally removed with any surplus metal by grinding &c.

Title: Process for the production of hydrogen peroxide
IPC: C01B15/03
Filed: 1954-05-24
Abstract: <PICT:0752501/III/1> In the recovery of hydrogen peroxide from an aqueous solution of persulphuric acid by falling film distillation under very low pressure, e.g. 40 m.m., the solution is passed through at least two distilling tubes arranged one above the other, steam substantially free from hydrogen peroxide being withdrawn from above the point of maximum pressure in the upper tube and passed into the lower tube, in co- or counter-current flow, so as to strip the solution of additional hydrogen peroxide.  Solution from two or more upper distilling tubes may pass to a single lower distilling tube. As shown, the solution flows successively down the inner surface of an upper distillation tube A, hydrogen peroxide separator L, and lower distillation tube C.  Reduced pressure is applied at cock G.  A baffle T is placed at the point of maximum pressure in tube A.  Steam substantially free from hydrogen peroxide is withdrawn through pipe R1 and passes through pipe R2 up lower distillation tube C in counter-current flow to the solution.  A mixture of steam and hydrogen peroxide is removed from separator L and passed to a rectifying column for concentration of the hydrogen peroxide.  A portion of the steam may be bled off at D.  In an alternative arrangement (Fig. 2, not shown), the steam may pass into the lower distillation tube in concurrent flow.  In the example a solution equivalent to 35 gr./l. of hydrogen peroxide was employed with a throughput of 20 l./hr.

Title: Improvements in and relating to the control for electric furnaces and the like
IPC: H05B3/00
Filed: 1919-06-19
Abstract: 143,737. British Thomson - Houston Co., (General Electric Co.). June 19, 1919. Resistance furnaces.-In electric furnaces, the temperature of the heating element is controlled by two automatic devices set for different temperatures. Only one of these is in use at a time, and the selection is effected by an automatic device dependent on the temperature of the furnace charge. In the arrangement shown, a heating- element 2 heats a charge 3, which may be in the nature of steel blocks, shafts &c., and receives current through a switch 4. A thermo-couple 20 in good thermal relation with the heating-element is connected to two devices B, C in parallel. These devices are of the galvanometer type, adapted at certain temperatures of the thermocouple 20, to change over contact members 12b, 12<c> from the left-hand position where they are in touch with contacts 13<b>, 13<c> to the right-hand position, where they are in touch with contacts 14b, 14<c>. In both positions, the contacts 12<b>, 12<c> are in periodic touch with continually-reciprocating contacts 15<b>, 15<c> actuated by electric motors 16<b>, 16<c>. By this means intermittent impulses of current are sent to one or the other of a pair of solenoids 9, 10 actuating a two-position relay 7, 8 which opens and closes the circuit of the electro-magnet 4 of the heating-current switch. The intermittent opening and closing of the switch 4 regulates the temperature of the heating-element as demanded by the thermo-couple. Only one of the devices B, C, is operative at a time. The selection depends upon a thermo-couple 18, in conducting relation with the outside of the charge 3, and a device A, similar in construction to the devices B and C, and controlling a two-position relay 23. Adjustments are so made that the device C, set to a temperature of say 1800 degrees, is in control during the heating up of the charge from the cold, and that the device B, set to a temperature of say 1540 degrees, takes over the control when the charge has been heated up say to 1500 degrees.

Title: Method for obtaining highly porous slag
IPC: C21B3/06
Filed: 1920-06-14
Abstract: 145,032. Schol, C. H. Aug. 29, 1914, [Convention date]. Slags, treatment of.-In the preparation ot porous lumps of slag, the formation of a glassy surface to the lumps is prevented as far as possible by introducing the slag into heated water at as near the water level as possible. The Specification as open to inspection under Sect. 91 (3) (a) describes several other methods, and also apparatus for effecting this object. As shown in Fig. 1 (Cancelled), molten slag is conveyed by a shoot 1 to an inclined or horizontal surface 2 which may form an extension of the shoot 1, situated at about the level of the water which is heated in a vessel 10. The slag swells up and floats on the surface of the water, from which it is immediately removed by an elevator 3, which dips slightly below the surface of the water, and delivered to trucks 4. Fine particles sink into a sump 9, whence they are removed by an elevator 6 into a silo 7. The shoot 1 may have two outlets opening respectively opposite the elevators 3, 6, so that by directing the slag to one or other of these outlets, it may be converted at will into porous lumps or sand. Existing plant may be modified as shown in Fig. 4 (Cancelled) by placing a plate 8 at or near the surface of the water, on to which the slag falls, and from which it flows horizontally on to the surface of the water. In another method for producing the same result, the molten slag is allowed to flow over an inclined perforated surface, through the perforations of which steam passes upwards through the slag. In another method, shown in Fig. 7 (Cancelled), molten slag is led to a shoot c which widens towards its delivery end, and down which a stream of water flows from a pipe d. The heat of the slag vaporizes the water, which permeates the slag, and causes it to froth up. The lumps thus formed are delivered to trucks e by a shoot f which may be perforated to allow surplus water to drain away. If the shoot f has a small inclination it may be caused to vibrate to assist the passage of the lumps. This subject-matter does not appear in the Specification as accepted.
