Title: Improvements in or relating to filter plugs for cigarettes
IPC: A24D3/04
Filed: 1947-06-02
Abstract: In a cigarette plug having two aligned portions of plug material, the two portions are secured by adhesive to their wrapper, at least near their adjoining ends.  The plug material may comprise super-imposed layers of crepe paper which may be rendered non-absorbent.  It is stuck inside the paper wrapper by a line of adhesive extending longitudinally, or adjacent the ends of the portion only.  When the material is cut into individual plugs the ends are thus prevented from falling out of their wrapper.  Specification 623,939 is referred to.

Patent GB-873997-A (GB)
Title: A process for the removal of lower oxides of nitrogen from gaseous mixtures containing them
IPC: B01D53/56
Filed: 1959-04-29
Abstract: <PICT:0873997/III/1> NO and NO2 are removed from a gaseous mixture by reacting the oxides with magnesium hydroxide and/or carbonate in aqueous suspension to form magnesium nitrite, and heating to decompose the nitrite to NO, Mg(OH)2 and Mg(NO3)2.  The concentration of nitrite in the washing liquid is maintained at 200-300 grms/1. by dilution and the solids content is 20%, or less.  An alkali, alkaline earth metal, or magnesium nitrate should be included in the wash liquor.  Residual gas from the acid absorption stage of an HNO3 plant enters tower 1 at 14 countercurrent to an aqueous solution of Mg(NO3)2 containing suspended Mg(OH)2.  NO or NO2 should be added to the waste gas to ensure that NO and NO2 mixture is present as N2O3 proportions.  The wash liquor passes to pressure vessel 2 heated by steam coil 5 where, at 140 DEG -200 DEG C., the Mg(NO2)2 is decomposed to NO, Mg(OH)2 and Mg(NO3)2.  The NO is oxidised in chamber 4, after decompression to maintain a pressure 3-6 atms., and returned either to the waste gas feed to tower 1 or to the HNO3 plant at 13.  From 2 the wash liquor passes to precipitation tank 3, with, or without, separation of the Mg(OH)2, where addition of alkali, or alkaline earth, metal carbonate, or NH3 and CO2 converts Mg(NO3)2 to Mg(OH)2, MgCO3 and basic carbonate which may be returned to the wash liquor cycle 12 through 9 after separation of the nitrate formed. Decomposition liquor from pressure vessel 2 may also be returned to the cycle through 11.

Title: Improvements in or relating to photographic type-composing apparatus
IPC: B41B21/16
Filed: 1957-05-09
Abstract: 821,895. Photographic type-composing. HEINE, H. May 9, 1957 [May 14, 1966], No. 14828/57. Addition to 725,699. Class 98(1) [Also in Group XL(b)] In a photographic type-composing apparatus in which the magnification of the symbols projected on to photo-sensitive sheet material is adjustable by movement of lens elements without movement of the symbols and sheet and the feed of the sheet between successive symbol projections is correspondingly adjustable under the control of characteristic marks on the symbol carriers, these characteristic marks are sensed by a photo-cell. In one form, Fig. 1, in which a symbol A on a carrier 11 is projected on to a photo-sensitive sheet 10 by a lamp 28 and lenses 29 and 21, 22, the lamp 28 and lenses 21, 22 being adjustable by a rotary cam 25 to vary the magnification, the feed of the sheet 10 is stopped when light from the lamp 28 passing by way of a characteristic slot 27 in the symbol carrier 11, lenses 21, 22, mirror 30 and a slot 33 in a slidable shutter 31 mechanically coupled to the sheet feed falls on a photo-cell 34. In a modification, Fig. 2 (not shown), the light passing through the slot 27 is doubly reflected by a prism and passes through adjustable lenses in a path paralled to the main light beam to fall on a slidable shutter and photo-cell. In a further modification, Fig. 3 (not shown), the photo-cell shutter is pivoted. In another form Fig. 4, the symbol carrier comprises a disc 411 angularly adjustable by a hand lever 522 cooperating with a scale 523. The disc carries three annular rows of symbols and is adjustable vertically in steps by a manually adjustable slide 516. Magnification of the symbols on the photo-sensitive sheet 410 is varied by altering the separation of lenses 421, 422. This is effected by a cam member 561 which is rocked by a fixed cam 560 when it is moved longitudinally by a rack and pinion 564, 565 operated by a knob 426. An iris diaphragm 539 between the lenses moves with the member 561 and is adjusted by a fixed cam 540. Light passing through a control slot 427 is directed by a prism 555, lens 556 and oscillating mirror 645 on to a screen 431 having a slot 433 behind which is a photocell 434. A feed slide 590 which is operated by a cam 580 driven from a motor 570 through a one-revolution clutch 572, 573 feeds the photo-sensitive sheet 410 until it is disengaged by the photo-cell. The mirror 645 is operated from the feed slide 590 through a lever 640, pin 642, which is adjustable by a cam 657, coupled to the magnification adjusting cam 561, and a lever 644. The photo-sensitive sheet 410 is supported in a dark-slide 610 and line spacing is effected by a hand lever 614. Shaft 578 of cam 580 carries cams N 1-6 controlling contacts W 1-6 for controlling machine operations. The step-by-step feed of the sheet 410 is also adjustable by a stop screw 600 and/or by relatively turning discs 652, 653 by a knob 656. Characteristic slots for different spacings between words are provided on the disc 411.
