Abstract: 1,172,346. p-Fluorophenethylamine derivatives. PARKE, DAVIS & CO. 20 May, 1968 [26 May, 1967], No. 24005/68. Heading C2C. Novel α,α-dimethyl-#-ethyl-#-(p-fluoro)-phenethyl-amines of the formula where R is H or CH 3 , and their acid addition salts, are obtained (a) by reducing the corresponding N-benzyl compounds with hydrogen in the presence of a catalyst, (b) by subjecting N - [α,α - dimethyl - # - ethyl - # - (p - fluoro)- phenethyl]-formamide to hydrolysis in the presence of an acid or base catalyst or reducing it with LiAlH 4  or LAlH 4 -ACl 3 ; (c) by reducing 2,2-dimethyl-3-ethyl-3- (p-fluorophenyl)- aziridine using hydrogen in the presence of a noble metal catalyst; (d) by reducing N- methylene - α,α - dimethyl - # - ethyl - # - (pfluoro)-phenethylamine using NaBH 4 , Na in alcohol, Al amalgam, Mg-MgI 2 , LiAlH 4  or HCOOH; or (e) by hydrolysing an N-arylidene- α,α - dimethyl - # ethyl - # - (p - fluoro)- phenethyl-methylammonium salt. The free bases can be converted to acid addition salts by reaction with organic and inorganic acids. The free dl bases can be resolved into d and l isomers using the d- or l-form of tartaric acid in conventional manner. The preparation of starting materials is described as follows:- Fluorobenzene is reacted with isobutyryl chloride in the presence of AlCl 3  to form pfluoroisobutyrophenone which is reacted with ethyl magnesium bromide to yield 1-ethyl-1-(pfluorophenyl) - 2 - methylpropan - 1 - ol which is dehydrated to form 2-methyl-3-(p-fluorophenyl)- 2-pentene. This product is treated with benzonitrile to form N-[α,α-dimethyl-#-ethyl-#-(pfluoro)phenethyl]-benzamide which is reduced with LiAlH 4  to N-benzyl-α,α-dimethyl-#-ethyl-#- (p-fluoro)phenethylamine. A mixture of this compound and formaldehyde is treated with formic acid yielding N-benzyl-α,α-N-trimethyl-#- ethyl - # - (p - fluoro) - phenethylamine. 1 - Ethyl- 1 - (p - fluorophenyl) - 2 - methylpropan 1 - ol is reacted with NaCN and acetic-sulphuric acid mixture to form N-[α,α-dimethyl-#-ethyl-#-(pfluoro) - phenylethyl] - formamide. p - Fluoroisobutyrophenone, 1,1 - dimethylhydrazine and p-toluenesulphonic acid are refluxed to form pfluoroisobutyrophenone dimethylhydrazone which is reacted with methyl iodide to form the corresponding trimethylhydrazonium iodide which is reacted with sodium isopropoxide forming 2,2 - dimethyl - 3 - (p - fluorophenyl) - azirine; this is reacted with EtMgBr to form 2,2-dimethyl - 3 - (pfluorophenyl) - 3 - ethylaziridine. dl - α,α - Dimethyl - # - ethyl - # - (p - fluoro)- phenethylamine is refluxed with paraformaldehyde to form N-methylene-α,α-dimethyl-#- ethyl-#-(p-fluoro)-phenethylamine. The same starting material is refluxed with benzaldehyde to form dl-N-benzylidene-α,α-dimethyl-#-ethyl-# (p-fluoro)-phenethylamine which is reacted with CH 3 I to form the methiodide. Pharmaceutical compositions which exhibit an appetite-depressant or anorexic effect when administered orally or parenterally comprise as active ingredient a compound of the above general formula.

Title: A method of forming a meat curing salt product
IPC: A23B4/32
Filed: 1935-08-30
Abstract: 455,816. Salt preparations for curing meat. GRIFFITH LABORATORIES, Inc., 1425, West 37th Street, Chicago, U.S.A. Aug. 30, 1935, No. 24275. Convention date, Nov. 7, 1934. [Class 49] A meat-curing salt preparation is obtained by forming on grains of sodium chloride a coating of a meatcuring nitrate or nitrite, or both, the sodium and potassium salts being preferably used. These salts may be applied as a strong solution to the sodium chloride crystals, the temperature of which may be so high as to evaporate the water from the solution and fuse the residue. The salts may alternatively be applied in fused state, the sodium chloride crystals being sufficiently hot to maintain a fused coating thereon. The coating may be effected by tumbling sodium chloride in a heated drum, the surface of which is coated with the liquid substance, or by agitating the sodium chloride in a vessel and spraying on the liquid. It may also be effected in a continuous process in which the hot sodium chloride crystals are sprayed whilst being carried on an endless belt or a roller. Where a hot roller is employed it may be coated with a strong sodium chloride solution which may contain nitrate or nitrite or both and is evaporated and the residue coated. The sodium chloride grains to be coated may be prepared as set forth in Specification 437,898, containing nitrite or nitrate or both, and if non-included nitrite or nitrate or both are left outside the crystals, the mass may be heated to fuse these on the coating. The coated material is preferably cooled quickly and with agitation, e.g. by spreading in a thin layer or sprinkling through a cooling atmosphere as by dropping it through a tower. When for use in a dry state the mass is ground. In another form, a mixture of the salts to be united is made, e.g. 93 parts by weight of sodium chloride, 2 parts of sodium nitrite and 5 parts of sodium nitrate, and the mass is heated to a temperature sufficient to fuse the nitrite and nitrate but not the sodium chloride. In a further method, the fused nitrite or nitrate or both is sprayed on cold sodium chloride grains which may be scattered into the spray from a centrifugal &c. device. As shown, the coating is effected in a mixer 21 heated by a jacket 22 and having an agitator 24. The sodium chloride crystals 23 are sprayed with the fused product or solution supplied to a sprayer 25 through a pipe 26, heated by a jacket 39, from a pot 27 which is closed and is supplied with a gas under pressure and preferably dry from a supply 31 to discharge the liquid therefrom. When an aqueous solution is employed, an exhaust system 32 is included to remove water vapour, and the heating is effected by hot oil which is circulated by a pump 34 from the jacket 22 of mixer 21 through a heater 33 and a pipe 35 which branches directly back to mixer 21, or through a valved pipe 36 to a jacket 37 on pot 27, from which the oil returns to the jacket 22 through pipe 38a and jacket 39. A pipe 40 carries hot oil from jacket 39 to pipe 41.

Abstract: 461,086. Telemeters; gun sights. BRONZAVIA SOC. ANON. Aug. 31, 1935, Nos. 24407 and 24408. Convention dates, Aug. 31, 1934 and Oct. 22, 1934. [Class 97 (i)] [Also in Group XXI] In a telemeter comprising a lens which forms an image of the target, and means for determining the position of the image plane, which depends on the distance of the target from the lens, the lens employed or the effective portion thereof is of annular or ring-like form. In Fig. 4, the lens comprises an annular positive element F and a negative element F<1>, and the image is formed on 'a ground glass screen V which is fixed relatively to the lens F, F<1>. For focusing the image an .auxiliary positive lens L is used which can be displaced axially, e.g. by means of a spiral groove t in a rotatable disc D on which a range scale may be marked. A lens l is provided for observing the image. A lens I for sighting the target and for rough focusing may be provided at the centre of the lens F. To enable a gun to be elevated in accordance with the telemeter reading, the screen V may be provided with cross-wires and may be displaced at right-angles to the axis of the lenses by a slider C<1> engaging in a Slot t<1> in a disc D<1> turning with the disc D. If the telemeter is rigidly mounted on the gun, the whole is then tilted until the intersection of the cross-wires lies on the axis. Alternatively, the movement of the slider C<1> can be transmitted to the gun. In another form, the slider, instead of displacing the screen V, may be directly connected to the gun so as to tilt it to the correct angle of elevation.

Title: Improvements in or relating to fluid pressure amplifiers
Inventor: BOOSEY FREDERICK ROBERT
IPC: G05B11/44
Filed: 1955-08-26
Abstract: 804,374. Fluid-pressure servomotor control systems; valves. SIGMA INSTRUMENT CO., Ltd. May 10, 1956 [Aug. 26, 1955], No. 24587/55. Class 135. The outer portion of the upper side of a diaphragm 40 is open to a first primary pressure, e.g. atmosphere, via a pipe 27 and the space between spring bellows 23 and a casing part 9 whilst the corresponding portion of the under side of the diaphragm is acted upon by a second primary or signal pressure greater than atmospheric flowing through a pipe 25 and the space between a second spring bellows 20 and a casing part 10; the latter bellows are open to atmosphere by way of an opening 22. The force tending to lift the diaphragm consists of the sum of the force due to atmospheric pressure on an end plate 12 of the bellows 20, which is connected to the diaphragm 40, and the force due to pressure applied through pipe 25 acting on the outer portion of the diaphragm outside the bellows area; the force tending to lower the diaphragm 40 is that due to atmospheric pressure acting over the whole of its area since initially the interior-of bellows 23 is open to atmosphere through a pipe 37 connected to a pressure sensing mechanism such as an indicator, recorder or valve. The diaphragm 40 is therefore lifted against the loading of a spring 36 and the bellows 20, 23 and through a spigot 16 attached to the diaphragm lifts a ball valve 33 from its seat 32, the valve being secured by a rod 35 to a similar valve 18 seated in the spigot mouth. Highpressure air from an inlet 39 then flows through the seat 32 into the pipe 37 as well as the interior of bellows 23 so lowering the diaphragm 40 against the primary pressure applied to the pipe 25. With the diaphragm in its initial position both valves 18, 33 are again seated. If the pressure in the pipe 25 falls the diaphragm is lowered and the spigot 16 moves away from the valve 18, since the rigid valve assembly cannot be lowered beyond the positions defined by the seat 32, and the interior of bellows 23 is open to atmosphere at 22 via a passage 14 through the spigot and diaphragm and the bellows 20 whereby the pressure in the pipe 37 falls until the upward force on the diaphragm due to the pressure in the pipe 25 lifts the diaphragm and the valve 18 is closed. This reciprocation of the diaphragm is continuous and rapid, allowing weak signals comprised by the difference between the pressures in pipes 25 and 27 to be reproduced as a secondary pressure on a magnified scale in pipe 37. When the pressures applied to pipes 25, 27 are equal an adjustment of the position of seat 32 enables an above atmospheric pressure to be obtained in the pipe 37. The apparatus may be used with gases other than air, and with liquids. One or both of the pressures applied to the pipes 25, 27 may be above or below atmospheric and both pressures may vary.

Title: Method of coating articles
IPC: B05D1/24
Filed: 1959-07-17
Abstract: An article having sections of different heat capacity in a ratio of at least 2 to 1 is coated with a pulverulent coating material by heating the article to a temperature which permits the coating material to adhere to and coalesce on the section of higher heat capacity without damage, this temperature being sufficient to produce a coating of powder on the section of lower heat capacity but insufficient to allow said powdered coating to coalesce, applying said pulverulent coating to the entire heated article, allowing the article to cool and thereafter heating the entire coating to coalesce the coating on said portion having lower heat capacity.  The coating material may take the form of a fluidized bed; it may be polystyrene, epoxy resin, cellulose acetate-butyrate, polymerized epsilon caprolactam, polyvinyl chloride, porcelain, bitumen, shellac, glass, wax or silicone resin, and may contain abrasives, fillers such as powdered asbestos, slate, metal powders, pigments, or polytetrafluoroethylene.  The article may be of metal, e.g. steel or cast iron, or of wood, glass, or ceramics; articles mentioned include finned tubes, refrigerator and plating racks, balance rings and chair bases.

Title: Internal combustion engine with exhaust gas recycling system and method for operating such engine
IPC: F02B47/10
Filed: 1975-06-09
Abstract: 1513958 Closed-cycle engines SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 9 June 1975 [11 June 1974] 24650/75 Heading F1B A method of operating a closed-cycle I.C. engine with exhaust gas re-cycling comprises the steps of supplying hydrocarbon fuel and pure oxygen to the engine, recycling exhaust gas from the exhaust manifold to the inlet manifold, treating at least part of the exhaust gas during the recycling step to liquefy CO 2  and removing liquefied CO 2  from the recycled gas. An apparatus for carrying out the method includes an I.C. engine 2 leaving an exhaust manifold 3 leading to cooler 6 and valve 15 which directs some of the exhaust gas through a conduit 13 and the remainder through a compressor 7, a cooler 8 in which carbon dioxide liquefies and a separator 9 which directs liquid into a pipe 17 leading to a pump 19 and storage chamber 20. The rest of the exhaust gas, substantially free of carbon dioxide, passes through pipe 16 and is mixed with oxygen evaporated from a storage tank 21. The mixed gases pass through control valve 10 and are further mixed with exhaust gas from conduit 13 before entering inlet manifold 4 via a heater 11. Hydrocarbon fuel from tank 23 is supplied to engine 2 through flow measuring device 25 which provides a signal, representative of the rate of fuel-flow, to controller 26, which also receives from sensor 28 a signal representative of the oxygen content of the mixed gases. Controller 26 adjusts valve 10 to maintain a flow of oxygen appropriate to the fuel-flow. In a second apparatus, the re-cycling circuit is combined with an absorption refrigeration system in which the gases leaving the exhaust manifold pass through a heat exchanger in the refrigeration system boiler, through a wet scrubber to a valve corresponding to the valve 15, to a drier, a cooler, a compressor and pre-cooler, and then to a final cooler which is the evaporator of the refrigerator system. The mixture of exhaust gas and oxygen fed to the engine is passed through a heater which utilizes the heat in the exhaust gas leaving the engine, or the liquid coolant used in the engine, or an electrical heater. The apparatus is suitable for use in a submerged vessel or diving bell. The engine has a compression ratio of over 18 e.g. between 28 and 55 and when operating at a C.R. of 55 on a mixture of carbon dioxide and oxygen the temperature at T.D.C. the same as that reached when operating on air with a C.R. of 17À5. The optimum compression ratio is stated to be 30.
