Abstract: Nitric acid is concentrated by exposing a down-flowing-mixture of the weak acid and a dehydrating agent, in a fractionating column <PICT:0407089/III/1> or tower, to a counter-current of weak nitric acid vapours from the distillation of the effluent collected at the base of the column, and exposing the partially denitrated effluent in a second fractionating column to a counter-current of steam, whereby denitration is completed.  Weak acid mixed with a dehydrating agent, for example sulphuric acid, is fed from vessel 1 to the fractionating tower 3.  A preheater 14 may be used.  Strong acid vapours are evolved at 5 and the effluent liquid enters externally heated vessels 6, the vapours produced passing back into the tower, and the residual liquid entering a second tower 8 supplied with steam from a pipe 9. The weak nitric acid vapours pass to the tower 3.  The liquid leaving tower 8 may be passed to a further externally heated vessel and the steam produced therein employed in tower 8.  The towers may be superposed and the heating vessels built into them.  The vessels 6 are arranged in series, each at a lower level than the preceding one, and may consist of jacketed tubes heated by steam or liquid, or of tubes or stills set in a furnace.  Alternatively, the tower 3 may be so constructed that a portion thereof can be heated.  The vapours from the top of the tower 8 may be led directly to the bottom of tower 3, or scrubbed in counter-current with cold water and the dilute acid obtained fed to the top of tower 3.

Abstract: 812,082. Combined transmitting and receiving systems. TOKYO SHIBAURA ELECTRIC CO. Ltd. Sept. 14, 1955, No. 26253/55. Class 40 (5). [Also in Group XL (b)] A travelling wave tube is included in the receiver arm 25 of a radar or like transmitterreceiver having a common duplexer (wave guide 18) and antenna so that received signals are amplified by the tube but transmitted pulses, by overloading it, are attenuated. Moreover, received signals are rotated through 45 degrees by a 45 degree twist coupler 21 transforming the waveguide from rectangular to circular and further rotated through 45 degrees by a Faraday rotator 24 so that, being parallel to a conductor plane 26 in the waveguide, they are reflected back to and are accepted by the receiver arm 25, but transmitted signals, being not affected by the plane 26, are substantially rejected by the branch arm 25. The rotations due to the rotator 24 and twist coupler 21 on the transmitter signal, however, both cancel out. An inclined conducting plane 27 eliminates signals whose orientation is not aligned with the coupler 21. In a modification the twist coupler 21 is replaced by a 45 degree Faraday rotator and the other rotator 24 arranged to produce an equal 45 degrees but opposite rotation between the transmitter input end 19 and the reflecting plane 26.

Title: Semic-continuous filament combination yarn
IPC: D02J1/18
Filed: 1971-04-19
Abstract: 1325259 Yarn production CELANESE CORP 19 April 1971 [6 April 1970] 26321/71 Addition to 1105968 Heading D1F A method for producing yarn from continuous filaments comprises passing at least two continuously moving tows of crimped continuous filaments through a common or separate tow opening and deregistering zone, the filaments of at least one tow being different from the filaments of the other tow(s), deregistering the tows, combining the tows if opened separately, slitting the resulting combined deregistered tow longitudinally into a plurality of fibrous strips and collecting these strips as combination yarns. Preferably the tows are each passed through separate tow opening and deregistering zones, separately deregistered and combined to form a combined tow prior to slitting. Prior to slitting, the tows may be spread into webs in one or more spreading stages. The method may be carried out in the apparatus shown in Fig. 1 wherein a tow 10 from bale 12 is passed through a banding jet 16 to a tow sopening zone consisting of the pairs of rollers 19, 21 and 22, 23. These pairs each consist of a roller having a smooth surface and a roller having a paterned, i.e. alternating bands and grooves, surface. The tow is thus subjected to a differential gripping action producing a relative shifting of the adjacent filaments longitudinally along the tow whereby the crimps are moved out of registry with one another. The tow then travels through spreaders 24 and 38 and then may be combined with one or more spread tows of different fibers and passed to a tow splitting zone consisting of a roller 62 having circumferential parallel circular V-shaped grooves 63, Fig. 2, not shown, separated by sharp parallel ridges 64 operating in conjunction with a hot wire apparatus 66 comprising a series of spaced electrically heated wires 67 penetrating the web in alignment with each ridge 64. The narrow web bands so produced are diverged to eye guides 71 and take up with twist on to bobbin 72.
