Abstract: 1471766 Removing radioactive contaminants from gas LICENTIA PATENT VERWALTUNGS GmbH and BERGWERKSVERB- AND GmbH 3 April 1974 [4 April 1973] 14831/74 Heading B1L A plant for removing radioactive contaminants from exhaust gas comprises at least two adsorber units arranged in parallel, valve means whereby, in use, gas is passed through the units in turn, means for passing scavenging gas (e.g. CO 2 , NH 3 , water vapour) through the units to regenerate them, and active carbon delay path means which can be connected to each unit when it is being regenerated, so as to receive desorbed gas therefrom. Each unit may comprise one adsorber reactor or a plurality of adsorber reactors connected in series. In Fig. 2 the plant comprises two units each comprising two activated carbon adsorber reactors 21a, 21b and 21a', 21b' respectively, and activated carbon delay path means 115. In use, exhaust gas containing krypton and xenon nuclides, from line 12 is passed through valve 13 and reactors 21a, 21b to chimney 18 until krypton breaks through reactor 21b. The gas from line 12 is now passed through reactors 21a', 21b' and the reactors 21a, 21b are regenerated. The pressure in reactors 21a, 21b is reduced by pump 201, the withdrawn gas being passed to reactors 21a', 21b'. Valves 27, 224, 213 are set so that scavenging CO 2  gas from vapouriser 212 is passed through the reactors 21a, 21b in series until all the krypton is flushed from reactor 21a into reactor 21b, substantially all the xenon remaining in reactor 21a. Valve 225 is then closed and valves 224, 213, 231 set so that reactor 21a is treated with CO, from vapouriser 219 and reactor 21b with CO 2  from vapouriser 212 to produce a krypton-containing and a xenon- containing stream. CO 2  is removed from the xenon and krypton streams in condensers 218 and 211 respectively. The xenon is passed to chimney 18 via delay path means 115. The reactors 21a 21b after regeneration, are pressurised and are ready for use when the adsorption step of reactors 21a', 21b' is completed.

Title: Improvements in or relating to a method and apparatus for making mouthpiece cigarettes
IPC: A24C5/52
Filed: 1949-06-02
Abstract: 685,761. Cigarette-making machines. MOLINS, D. W., RUAU, F. F., JACKSON, N. W., and MOLINS MACHINE CO., Ltd. May 18, 1950 [June 2, 1949; Sept. 22, 1949], Nos. 14835/49 and 24417/49. Class 130. In a machine making a continuous composite rod of tobacco filler lengths T and stubs S from an unwrapped tobacco stream interrupted at intervals by the feeding of the stubs thereto, tobacco in the leading end part of each separated filler length is positively engaged and accelerated so as to cause it to move forward faster than tobacco behind it in the length. Tobacco showered from a hopper (not shown) onto an endless moving band 2 passes through a guide tube 3 and into and through a flute of a fluted drum 4 which is intermittently rotated to cut sections from the tobacco stream and replace them by stubs S delivered into the drum flutes as from a vertical shoot 5, the composite rod thus formed passing through a further guide tube 6' onto a paper web 19 moving more slowly than the band 2 and which carries the rod beneath a tongue 7 to the usual gumming and folding devices (not shown) of a continuous rod cigarette-making machine, the wrapped rod being later divided into mouthpiece cigarettes by cutting it through the middle of the stubs and tobacco lengths. An arm 15 pivoted both on a rotary disc 14 and, by a link 17, to a fixed point 18, has finger portions 12, 13, which may be 16 mm. apart, moving in the paths indicated by chained lines so as to enter, through a slot in the tongue 7, the leading end of each length T as it passes under the tongue. The leading finger 12 enters the path of the tobacco about 5 mm. behind a stub, and thereafter moves faster than the web 19 so as to act in the manner of the invention and tend to cause both closer abutment between the relevant length T and the preceding stub S and the reduction of any inhomogeneity which may have been caused by compression of the leading end of the length T as during cutting. According to the first Provisional Specification, the finger 12 enters the path of the tobacco 3 mm, behind a stub, and, according to the second Provisional Specification, it enters about 8 mm. behind a stub. Specifications 430,742, 669,557 and 669,559 are referred to.
