Title: Louvre-type damper
IPC: F23L11/00
Filed: 1976-02-27
Abstract: 1509671 Valves RODENHUIS & VERLOOP BV 27 Feb 1976 [25 April 1975] 07793/76 Heading F2V [Also in Division F4] In an arrangement comprising a number of adjustable louvres 6 supported in a frame 2, 3, 4 mountable in a duct for hot gases, e.g. combustion-gas ducts of boilers, cement kilns or chimneys or exhaust-gas ducts of gas-turbine installations, the louvres are adjusted by a common pneumatic actuator 32 via respective linkage systems each comprising a pair of lever arms 15, 24 and a pair of links 26, 28 arranged to define a parallelogram. This avoids unwanted automatic adjustment of the louvres when differential thermal expansion of the arrangement occurs in use. The arms 24 are on bell-crank levers 21 the other arms 25 of which are connected to the actuator via a common rod 35. The levers 21 are supported on an H-section rail 16 connected at 17 to an extension 5 of the frame. Thus the rail is spaced from the hot-gas path and therefore remains relatively cool in use. The consequent relative thermal expansion between the frame and rail causes relative movement between the centres of the respective pairs of pivots 7, 22 but the arms 15 are maintained parallel to the arms 24 by the links 26, 28, whereby the louvres are not moved from their fully closed or fully open positions. Since the relative movement between the respective pairs of pivots 7, 22 will increase with the distance from the connection 17, the lower end of the rail 6 is not fixed but is guided at 19 to permit compensatory movement thereof.

Abstract: 1489988 Multiple barrel launchers; dispensing Chaff A I MAGNUSSON 25 Feb 1975 [27 Feb 1974 6 March 1974] 7899/75 Headings F3C and F3A A launcher has a plurality of barrels 4 for the nearly simultaneous launching one from each barrel 4, of a plurality of projectiles (shells or rockets) by means of propelling gas generated by a pressure cartridge 5 common to a number of the barrels 4. The cartridge 5 being in communication with the barrels 4 via a pressure chamber 8 and channels 9 individual to the barrels 4 which channels 9 form chokes to ensure that the gas flow reaches critical velocity during at least part of the travel of the projectiles in the barrels 4. As particularly described and illustrated the projectiles 23 incorporate bundles 14 of strips of reflecting material which are to be spread out at a suitable height for the protection of a vessel against radar tracking missiles and aircraft. The launcher has a base block comprising three metal plates 1, 2, 3 for securing to the deck of the vessel, and the pressure cartridge 5 consists of a metal or plastics case serving as a container for a propellant 18 such as granulated boron and potassium nitrate. The ignition of the propellant 18 may take place mechanically or, as shown, electrically. The illustrated projectiles 23 are shells comprising a cylindrical case 11, a cap 12 and a reinforced bottom part 13. Below the bundles 14 there is a container for a pyrotechnical charge 15 for delivering when ignited propelling gas to force bundles 14 out of case 11. The strips are protected against combustion gases by a felt disk 16, and ignition of charge 15 takes place via a delay delement 17 containing a gasless pyrotechnical delay charge. A distance sleeve 25 (or an annular ridge or studs) supports the projectile in the barrel 4 to define a free space 26 between the mouth of channel 9 and projectile 23 and this space may also be defined by having the shell wall project some distance below element 17-the space 26 suitably has a length of barrel at least equal to (preferably of the order of twice) the diameter of same to limit maximum pressure. In use, the required number of shells are accelerated from the barrels 4 by the gases from propellant 18 when it is ignited-during passage in the barrels 4 the element 17 is ignited and after a time ignites charge 15 to throw out the strips at the desired altitude. When rockets are fired, their motors are ignited by the gases in the barrels. The barrels may be given different elevations. Certain of the projectiles may contain IR jamming means such as torches.

Patent GB-470717-A (GB)
Title: Improvements in or relating to the manufacture of saponaceous organic sulphides
Filed: 1936-03-19
Abstract: Aliphatic mercapto carboxylic or sulphonic acids or their derivatives are added to organic compounds which are free from carboxylic, sulphone, or sulphoxide groups and triple bonds and contain at least six carbon atoms and one olefinic double bond. Esters, amides and in the case of the carboxylic acids, the nitriles are specified derivatives of the mercapto components which may be used.  According to modifications of the invention, aliphatic mercaptans are used which contain (a) halogen atoms, or (b) hydroxy groups the latter atoms or groups being subsequently replaced by carboxylic or sulphonic groups.  Thus (a) the halogen is replaced by the sulphonic group by treating the sulphide formed as intermediate product with a sulphite or by the carboxylic group by treating with a cyanide followed by saponification and (b) hydroxy sulphides are strongly sulphonated to introduce a sulphonic group or the hydroxy group is replaced by a mineral acid residue e.g. halogen which is treated as (a) above.  The resulting sulphides have saponaceous properties.  In examples, mercaptoacetic acid is reacted with the following olefinic compounds; decene, a -dodecene, tridecene, tetradecene, a synthetic benzine containing about 20 per cent of olefine, cyclohexene, ethyl-, amyl-, isohexyl-, octyl-and nonyl-cyclohexenes, hexahydrobenzyl-cyclohexenes decahydromenaphthylcyclohexenes, octohydronaphthalene, isopropyloctahy-dronaphthalene and cyclohexylcyclohexene.  The use of the following mercaptocarboxylic and sulphonic acids and derivatives thereof are mentioned: thiolactic acid, a -mercaptobutyric acid, a -mercaptolauric acid, b -mercaptoethane - a  - sulphonic acid, g -mercapto-b  - hydroxypropane - a  - sulphonic acid, mercaptoacetylaminoethanesulphonic acid and its N-methyl compound. Specification 444,501 is referred to.  Samples have been furnished under Sect. 2 (5) of products derived from the following pairs of components; (a) mercaptoethylacetate and dodecene; (b) mercapto acetic acid and cetene; and (c) mercaptoacetic acid and an isoalkylmethylcyclohexene mixture derived, by removal of water, from an isoalkyl methylcyclohexanol mixture (the iso alkyl group containing 8 to 12 carbon atoms).  Mercapto carboxylic and sulphonic acids.--These are prepared from the corresponding chlor or brom carboxylic or sulphonic acids by treatment with sodium hydro sulphide.  Thus g -mercapto - b  - hydroxypropane - a -sulphonic acid is prepared by treating with sodium hydrosulphide, g -chlor-b -hydroxypropane - a  - sulphonic acid--which is obtained from glycerol dichlor hydrin by treatment with a sulphite. Mercaptoacetylaminoethanesulphonic acid and the corresponding N-methyl compound are obtained by condensing mercaptoacetic acid with taurine and methyltaurine.  Alkylcyclohexenes, hexahydrobenzyl cyclohexene and decahydromenaphthylcyclohexene are obtained by hydrogenation of the corresponding substituted phenols vis, alkylphenols, benzylphenol and menaphthylphenol followed by removal of water.
