Title: Improvements in or relating to the removal of nicotine and other toxic vapours from tobacco smoke
IPC: A24B15/28
Filed: 1932-12-30
Abstract: A substance for use in smoking tobacco, and serving to remove nicotine and other toxic vapours, is composed of (1) ferric sulphate, aluminium sulphate, or other material which, on heating, will liberate a substance, for example sulphur trioxide, which combines with the nicotine, (2) a binding-material, and (3) an oxidizing-agent which has the effect of preventing, for example, the formation of sulphur dioxide from the trioxide.  The binding-material may be formed by dissolving 20 parts of ethylcellulose in 80 parts of carbon tetracholride to form a very viscous solution, and to this may be added 70 parts of ferric sulphate, and 10 parts of potassium nitrate, serving as the oxidizing-agent.  Alternatively, nitrocellulose may serve both as the binding and oxidizing-agent.  The composition is pressed out into thin rods, which are then dried in a vacuum drier, and are inserted in the end of a cigar or cigarette which is to be lighted, or in the pipe.

Title: Air Line Filter
IPC: F16T1/24
Filed: 1967-08-14
Abstract: 1,195,256. Air line filter; centrifugal separator. BASTIAN-BLESSING CO. 14 Aug., 1967 [18 Aug., 1966], No. 37269/67. Headings B1T and B2P. A filter for removing solids and condensate from a compressed air line comprises a twopart housing 10, 76, baffles 57, 58, 70, 72, vanes 82 which give the incoming gas a rotary movement, a re-entrant shaped sintered bronze filter element 60, a lower sump in which liquid and solids accumulate below baffle 72 and a liquid discharge valve, whose opening is initiated by a float but effected by the pressure within the housing. A coloured indicator 46 is lifted into view within transparent dome 38, when diaphragm 48 is snapped over by rising differential pressure, and may be retained by ring 55 until manually reset after removing dome 38. The upper edge of element 60 has a rubber-dipped seal, and the element and baffles 57, 58 are clamped in place by assembly 30, 64. The discharge valve and float are shielded by screen 194, which excluding large particles from the valve. The two parts 10, 76 of the housing are held together by a ring 278, whose castellated flange segments make a bayonet connection with those on part 10, a latch 294 thereafter preventing rotation. In Fig. 2 (not shown) an annular float (128) opens a pilot valve (124) through leverage, thereby directing the line air pressure into a chamber (100) urging piston (106) leftwards to open the main discharge valve (138) to discharge liquid through passage (114) in member 90. A bleed passage (144) through the piston facilitates return of the piston rightwards, when valve (124), closes, and is kept clean by pin 152. In Fig. 3 (not shown) the discharge valve is formed by seat (164) and piston (106a) which is raised by line pressure when float (128) opens pilot valve (186) to expose the upper side of the piston to atmospheric pressure through passages (168, 114). A bleed passage (144a) restores the pressure to lower the piston when valve (186) closes.

Title: Electronic amplifier
IPC: H01J43/04
Filed: 1938-12-22
Abstract: 525,402. Electron multipliers. FARNSWORTH TELEVISION, Inc. Dec. 22, 1938, No. 37271. Convention date, Jan. 5. [Class 39 (i)] In an electron multiplier the electron stream is caused to undergo alternate multiplication and attenuation by absorption of part of the stream; the output current is of the same order as the primary electron current and the D.C. component is reduced in radio &c. signal amplification. A helical channel is formed, three cylinders 7, 8, 9, Figs. 1, 2 and 3 with vanes 11, these cylinders surrounding a central anode 2 ; the wall of cylinder 9 has grids 10 between alternate sections of the channel. A collector electrode 3 which may be a wall coating surrounds the cylinders and a screen 12 at anode 2 potential is interposed between the cylinders and the output electrode 13, the primary electrode for the multiplier may be thermionic, photo-electric, or an electron multiplier which may be of the kind described in Specification 471,199. The grids 10 have a slight negative bias and the cylinder 7 receives a driving A.C. ; the electrodes 2, 3, 13 receive positive potential in that order, an input signal being applied to the grids 10. An electromagnet 14 causes flow of the stream in the helix. The time of flight of the electrons round the three part cylinder is related to the impressed A.C. voltage so that electrons will be accelerated towards the secondary emitting surfaces on the cylinders 7 and 8 but will be slowed down as they approach the grids ; part of the stream will pass through these grids and be taken up by electrode 3. In a modification the longitudinal movement of the stream is effected electrostatically by means of grids 40, Fig. 6, on the anode 2, and grids 42 on the electrodes 7, 8 and 9. The A.C. potential on the cylinder 7 may be supplied by the primary multiplier described in the Specitication referred to above. The absorption of the electrons may be obtained by making the cylinder 9 slightly positive and without grid surfaces.. The signal can be applied to the multiplier cylinders 7, 8. The grids 10 may be omitted, attenuation being controlled by the potential of the edges of the openings in the electrodes. The Specification as open to inspection under Sect. 91 also describes (i) an arrangement consisting of a number of multiplier stages in cascade, a control grid being interposed in some of the stages; (ii) the use of a single stage of attenuation; and (iii) static potential control of the electrodes. This subject-matter does not appear in the Specification as accepted.

Abstract: 968,221. Generators operating by electromagnetic interaction with fluids. AVCO CORPORATION. Oct. 19, 1961 [Oct. 26, 1960; Dec. 2, 1960], No. 37497/61. Heading H2A. [Also in Division B5] In a magnetohydrodynamic generator the working fluid (hot ionized gas) passes through a duct whose walls 18 comprise a number of spaced longitudinally extending metal bars 19, e.g. copper, separated by insulating material 20, so that an acceptable wall working temperature is maintained. In a generator, having negligible Hall effect so that no longitudinal currents are formed, the walls as described above are clamped between electrodes 14, 17 (14 of carbon, 17 of copper) by bolts 25 and cooling fluid circulated through both electrodes and walls by tubes 23. The electrodes may comprise a number of separate parts distributed along the length of the duct to ensure a uniform current distribution. when the Hall effect is not negligible thermally conductive rods are used (Figs. 7 and 8, not shown) which project from a cooling passage formed by two spaced plates of insulating material and are surrounded within the duct by ceramic filling, e.g. " Blazecrete " (Trade Mark). The rods, which may be of any shape, are cooled by coolant being forced through channels incorporated in them by the pressure difference produced across the rod when coolant flows in the passage. In a generator operating under constant conditions the cooling conduits may be designed to follow the equipotential lines in the working part of the duct and the conduits are embedded in the wall of the duct and separated by the refractory lining of the duct (Fig. 12, not shown). In all constructions the thickness of the bar or rod is such that the voltage induced across it is less than that required to strike an'arc discharge between bars or rods and the risk is further reduced by chamfering the facing comers.

Title: Process and arrangement for the sterilisation of water
IPC: B01D29/39
Filed: 1976-09-16
Abstract: The process results in the required sterilisation efficiency both at high water flow rates and with highly polluted water. For example, the process is suitable for sterilising swimming-pool water. Water is fed from the swimming pool via a feedline (31) to a vessel (1). A partition (2) serves to calm the water. Filter plates (18) are arranged on their side edges in a filter chamber (4) and are each provided with a suction nozzle (20) at their top ends. The suction nozzles open into a pressure equalisation chamber (21) furnished at its bottom end with a suction line (23). This arrangement produces a uniform withdrawal of liquid from the filter chamber (4). Above the intermediate spaces between the individual filter plates (18) are arranged UV radiators (28). Constituents are taken off from the water surface via a take-off orifice (29). The filtered and sterilised water is returned to the swimming pool through a pipe (32). The flow velocity of the water within the filter chamber (4) is 0.5 to 50 cm/sec, so that a long residence time results for the water within the filter chamber (4) in the radiation region of the UV radiator (28). <IMAGE>
