Title: Improved manufacture of calcium nitrate from ammoniacal gases
IPC: C01F11/38
Filed: 1937-05-10
Abstract: In a method for the production of calcium nitrate, ammoniacal gases obtained by the distillation or gasefication of fuels or similar ammoniacal gases, after being freed from flue dust, tar, and hydrogen sulphide, are treated with aqueous nitric acid or ammonium nitrate liquor containing nitric acid, the ammonium nitrate liquor produced is converted by burnt lime into calcium nitrate liquor and gaseous ammonia, and the latter catalytically oxidized to nitric acid which serves for the absorption of more ammonia.  In a modification, hydrogen sulphide is first removed from the gases by milk of lime, and the calcium hydrosulphide solution formed reacted with the ammonium nitrate obtained by absorbing the ammonia to produce a calcium nitrate liquor and a mixture of hydrogen sulphide and ammonia.  From the mixture ammonia may be washed out by cold water, and air or gases containing oxygen be passed through the ammoniacal liquor to obtain a gas mixture which is converted to nitric acid.  In the ammonia absorption step, the gases may first be treated in countercurrent with the ammonium nitrate liquor produced, then with ammonium nitrate liquor containing nitric acid, and finally be treated with alkaline ammonium nitrate liquor to absorb entrained nitric acid.  The gaseous ammonia obtained by reacting the ammonium nitrate liquor with burnt lime may be freed from water vapour by contacting it with cold ammonium nitrate liquor, whereby the latter is heated prior to its reaction with the lime. The calcium nitrate liquor, which preferably contains an excess of calcium oxide, is worked up in known manner.

[Class 138(i)] Relates to floor scrubbing machines of the type comprising a wheeled carriage 1 having means 8 for distributing washing liquid adjacent a mechanically-driven scrubbing brush 5 from a tank 16 mounted on the carriage and with an endless wiper band 32 which runs along the floor and between wringing rollers 25, 26, the liquid expressed by the rollers going to a waste tank 17. According to the invention the wiper band 32 is made from yellow buff hide or an equivalent stout hide having a buffed surface on one or both sides, the ends being joined to form an endless band. The carriage 1 is mounted on wheels 3, 4, the brush 5 being driven from the wheels 3 by means of gearing and connecting links 11 which reciprocate a cross-bar 9 to which the brush is connected. The crossbar 9 is connected to rods 7 which slide in bearings 6 on the machine frame 1. Liquid from the tank 16 is distributed over the brush 5 by the perforated pipe 8 which is fed from the tank 16 through a cock 20, which is connected by a cable to manipulatory means on a handle by which the machine is moved. The band 32 is carried by four rollers 21-24, and is arranged to sag between the lower rollers 23, 24 forming a bight 32a in contact with the floor The lower rollers may be adjustably mounted but are arranged so that they do not press the band on the floor. To keep the band in position laterally guide strips 33 are used. The upper part of the band passes between the two spring-pressed wringing rollers 25, 26, the upper of which is chain-driven from the rear wheels 4. The wiper band 32 is driven from the rear wheels 4 through a free wheel so that the bight 32a travels in the same direction as the machine at about 1¢ times the machine speed so that it wipes the floor. The band is made from " yellow buff hide," the buffed side absorbing the liquid. The ends are joined by skiving and lap joining fixed with cement and stitching or a butt join with wire or leather lacing or staples or  hooks may be used. It has a series of transverse rows of perforations to allow liquid expressed by the wringing rollers to run through. The forward upper band roller 21 may be mounted higher than the rear roller 22 or the wringing rollers may be positioned so that the band is depressed. The lower rollers 23, 24 may be closer spaced than the upper rollers 21, 22. Underneath the wringing rollers 25, 26, a catchment tray 30 is provided which drains into the removable tank 17. In a modification the brush 5, the band 32 and the wringing rollers 25, 26 are driven by an electric motor. The Provisional Specification states that a pair of inwardly and downwardly converging squeegees may be mounted between the brush and the band.

Abstract: 1,059,461. Testing fabrics. LACE RESEARCH ASSOCIATION. April 4, 1964, No. 13984/64. Heading D1S. Faults, in the form of holes, in a fabric 7, Fig. 1, such as lace, are detected by simultaneous engagement of a series of unequally spaced contact strips 1, 2, 3, 4, 5 arranged across one side of the fabric with a corresponding series of spring-loaded contact rollers carried in an insulating body which is traversed across the other side of the fabric on a rail 11. Any number of contacts and strips may be used, and they are connected respectively in pairs (Fig. 7) such that a circuit is completed between two points XX when a large enough hole appears, but not when merely a few of the contacts touch their respective strips through small holes forming an intended pattern in the fabric. The contacts XX are connected to a relay operating circuit (Fig. 9, not shown), which includes a cold cathode trigger tube to maintain reliable operation despite possible excessive contact resistance between rollers and strips. The individual strips may be replaced by one wide strip (20, Figs. 10, 11, 12, not shown) connected to one of the points X; and all the rollers are then connected via respective resistors (21 to 25) to the other point X, the relay circuit being preset to operate only when all the resistors are in circuit. This arrangement allows variation at will of the number of contact rollers used, merely by disconnecting a roller and resetting (at 26) the sensitivity of the relay circuit.. The relay is used to operate a warning device or to stop the machine.

[Class 21] In a device for drawing off liquid from containers, e.g. beer from barrels, a hollow cork 11, Fig. 7, e.g. of rubber is employed which has a diaphragm 35 so curved that pressure within the container tends to expand the cork and increases the efficiency of the seal. For tapping, the cork is pressed into the container by a nipple 26, 25, screwed with a left-hand thread into the end of the stem 36 of the tap, the nipple entering a recess 35 in the end of the cork and engaging by a thread 26<a> with a thread 34 on the cork so that when the tap is withdrawn the cork is re-introduced into the bung-hole bush and re-seals the container. A loose metal washer 31 takes the pressure between the nipple and the cork during the reintroduction of the cork. A resilient washer 37, ensures the sealing of the connection between the tap and container before the seal of the cork is broken, and ensures the reverse effect on withdrawing the tap ; A left-hand threaded strainer 11 may also be used in the stem of the tap, and may function to adjust the size of outflow apertures 19 in the stem. A cork of the form shown in Fig. 1, with reinforcing ribs 13, may also be used, the means for reintroducing the cork being omitted.
