Filed: 1933-05-06
Abstract: 420,295. Spray carburetters. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. May 6, 1933, No. 13239. Convention date, May 7, 1932. [Class 7 (iii)] A carburetter body formed in two sections has a float chamber and a double Venturi cast integral with one of the sections. A downdraught carburetter comprises an upper body portion 8, preferably of aluminium alloy and formed by die casting, and a lower body portion 9 preferably of cast iron and formed as a plain tube with relatively thin walls and separated from the upper portion by a non- conducting gasket 10. A choke valve 13 mounted on a shaft 14 is provided with a poppet valve 15. The upper section is cast with a float chamber 21 and also with an inner Venturi 36 and an outer Venturi 34, this being made possible by a fin 38 which contains the nozzle in the form of a tubular member 45 held in place by a metering plug 53. Tube 45 is cut away on its outer surface at 54 to provide an air-bleed passage, which communicates at one end with the bore of the tube through ports 56, and at the other end with the main air passage through a duct 60. The tube is also cut away circumferentially at 62 to provide communication with an idling duct 64, 66 which leads, through passage 72, Fig. 4, to a nozzle 76 beyond the throttle valve 19. The throttle is actuated through a lever 82 and the other end of the spindle has an arm 88, Fig. 5, connected to one arm 92 of a jointed lever the other arm 93 of which is connected to the rod 98, Fig. 4, of an accelerating pump. The members of the jointed lever turn about a pin 94, Fig. 3, and are normally held by a spring 97 so that the arm 92 is in contact with a stop 96 on the arm 93. On rapid opening of the throttle 19, the lever arms are relatively displaced against the tension of the spring with the result that the plunger of the accelerating pump has a slow and prolonged movement. The cylinder 102 of the accelerating pump is cast with the upper body section 8 and communicates with the float chamber through a port 103, Fig. 5. The lower end of the cylinder is connected through a port 111 with an accelerating-fuel nozzle 112, Fig. 4. In a modification, Fig. 8, (not shown) a second fin is provided in alignment with the fin 38, and the inner Venturi is provided at its upper end with a cap which constitutes the main nozzle.

Patent GB-593257-A (GB)
Title: Improved lubricating oil or grease compositions
Filed: 1945-05-28
Abstract: Lubricating oil and grease compositions particularly for use in the presence of moisture, such as turbine oils, contain a small proportion of an anti-corrosion agent comprising an alkyl mercapto derivative of a saturated aliphatic dibasic acid. Monalkyl mercapto and dialkyl mercapto derivatives may be used, particularly derivatives in which at least one of the alkyl groups contains at least 8 carbon atoms such as octyl, decyl, dodecyl, and cetyl. Derivatives of succinic acid are preferred and the cetyl compounds specified, viz., mono-cetyl mercapto succinic acid and di-cetyl mercapto succinic acid.  In use the compound may be neutralized with an amino base or may be used in the form of the anhydride or the half ester with common alcohols. The mono-alkyl mercapto succinic acids are prepared by the direct condensation of the mercaptan with maleic anhydride in the presence of a Friedel-Crafts catalyst such as boron fluoride, aluminium chloride &c. followed by hydration.  The dialkyl mercapto succinic acids may be prepared by first converting maleic anhydride to its mono-chlor derivative and then reacting this compound with two mols of the mercaptan to give the desired anhydride which is finally hydrated.  The second mol of mercaptan may be condensed in the form of an alkali mercaptide.  U.S.A. Specification 2,354,500 is referred to.ALSO:Mono-alkyl mercapto succinic acids are prepared by the direct condensation of the mercaptan with maleic anhydride in the presence of a Friedel-Crafts catalyst such as boron fluoride, aluminium chloride, &c., followed by hydration.

Title: Novel acetylenic esters and the conversion thereof into further esters
IPC: C07C69/145
Filed: 1955-05-09
Abstract: The invention comprises as new products acetylenic esters of the general formula: <FORM:0774621/IV(b)/1> wherein R1 is a hydrogen atom or a straight or branched chain alkyl radical containing up to ten carbon atoms, R2 is a straight or branched chain alkyl radical containing up to ten carbon atoms and R3 is an isoprenoid or hydrogenated isoprenoid radical of the formula: <FORM:0774621/IV(b)/2> <FORM:0774621/IV(b)/3> in which n is 1, 2, or 3.  The products may be converted by selective hydrogenation into olefinic esters of the general formula: <FORM:0774621/IV(b)/4> wherein R1, R2 and R3 are as defined above.  The acetylenic esters may be obtained by reacting an acetylenic tertiary carbinol of the general formula C ­ CH.C(R2)(R3)OH, wherein R2 and R3 are as defined above with an anhydride of the formula: <FORM:0774621/IV(b)/5> wherein R1 is a hydrogen atom or a straight or branched chain alkyl radical containing up to 10 carbon atoms (at least one R1 being such an alkyl radical), in the presence of an acidic esterification catalyst.  The reaction may be carried out at ordinary temperatures and with a slight molar excess of the anhydride.  Specified esterification catalysts are phosphoric acid and p-toluene sulphonic acid.  The various stereoisomeric forms of the acetylenic alcohols may be used to form the stereoisomeric forms of the acetylenic esters.  The selective hydrogenation to form the olefinic esters may be carried out by treating the acetylenic esters with approximately a molar equivalent of hydrogen in the presence of a hydrogenation catalyst, e.g. a lead-palladium catalyst, which selectively catalyses the reduction of an acetylenic bond preferentially to an olefinic bond.  The hydrogenation is preferably effected by treating a solution of the acetylenic ester in an inert organic solvent with hydrogen in the presence of a lead-palladium hydrogenation catalyst and quinoline at ordinary temperature and under slightly super-atmospheric pressure until about one mol. of hydrogen has been taken up.  Examples are given for the production of the racemic acetate, propionate, n-butyrate, isobutyrate, and formate of 3,7-dimethyl - octen - (6) - in - ol - 3 and of 3,7,11-trimethyl - dodecadien - (6,10) - in - (1) - ol - 3 from the alcohol and appropriate acid anhydride and for their conversion to the corresponding olefinic esters.  The formate esters are obtained by adding formic acid to acetic anhydride, maintaining the temperature below 30 DEG  C. by cooling until the evolution of heat has ceased, and then adding aqueous phosphoric acid and the acetylenic alcohol. An example is also given for the production of the acetate of racemic 3,7,11,15 - tetramethyl - hexadecin - 1-ol-(3) and the corresponding olefinic ester.  The acetylenic ester products are stated to be useful in the making of perfumes and scented compositions. Specification 711,010 is referred to.

Abstract: 1,225,256. Electro-erosion apparatus. CINCINNATI MILLING MACHINE CO. 19 March, 1968 [30 March, 1967], No. 13356/68. Heading B3V. [Also in Division H5] An electro-erosion apparatus has its erosion current controlled to reduce electrode wear by passing the current through a parallel inductance 5 and resistance 4 in series with the electrode gap 2, 3. The current is switched on by a rectifier 9 controlled by a pulse generator 8. Initially the full voltage of the D.C. source 1 causes a current i 0  to flow whose size is variable and determined by the variable resistance 4. After a short time current flows through the inductance 5 so that the current increases constantly to i 1 . The rate of increase is adjustable by the variable inductance 5. When a rectifier 10 is switched on by the pulse generator the condenser 7 is charged and the current across the gap falls rapidly and the rectifier 9 switches off, the condenser discharges in a time dependent on the inductance 5 and capacitor 7 values and charges a buffer capacitor 6. The cycle is then repeated by switching on the rectifier 9.
