Title: Method of and means for rendering a throttle controlled hydraulic system immune or substantially so to irregularities
IPC: B23Q5/26
Filed: 1931-06-15
Abstract: 386,010. Hydraulic transmission of power. CINCINNATI MILLING MACHINE CO., Cincinnati, Ohio, U.S.A.-(Assignees of Ernst, H. ; 3617, Edwards Road, and Goodrich, C. W. M. ; 6697, Bramble Avenue, both in Cincinnati, Ohio, U.S.A.) June 15, 1931, No. 17317. Convention date, June 16, 1930. [Classes 69 (ii) and 135.] A throttle-controlled hydraulic system is rendered immune from irregularities consequent on variations in viscosity or temperature of the liquid, and/or variations in work resistance, by means of a valve member controlled by the differential pressures created by a fixed resistance and the throttle ; the fixed resistance may be adjustable in value in some cases. In the form shown in Fig. 4, comprising a constant displacement pump 3 and a working cylinder M, a fixed resistance R<1> and a throttle R<2> are disposed in the supply and outlet sides of the system respectively. A part of the pump output is returned to a reservoir 1 through pipes 19, L, under the control of a valve member V carried by a member X ; the latter has surfaces A<1>, A<2> acted on by the pressures in front of and behind the resistance R<1>, and surfaces A3, A4 acted on by the pressures due to the throttle R<2>. In the form shown in Fig. 3, the surfaces A<2>, A<3> are amalgamated and the throttle R<2> is in the supply side of the system. In another form, the supply side is connected to an accumulator CP, Fig. 6, and a manually adjustable throttle R<2> or a throttle Rx adjustable manually or automatically from the driven member is employed. Other systems employing an accumulator and with parts arranged in a different order are indicated in Figs. 7 and 9. As shown in Fig. 11, several motors each with its own throttle R<2> may be supplied through a common main B from one pump, and one resistance R<1> may serve for all. In all forms, the constant-discharge pump 3 may be replaced by a variable-discharge pump, which may be set to yield any desired constant output, the setting means being preferably linked to means for varying the fixed resistance R<1>, as indicated in Fig. 13 ; if desired, a piston 43, Fig. 14, subject to the pressure beyond the fixed resistance may set both the pump and the fixed resistance. Specification 297,104, [Class 69 (ii), Hydraulic presses &c.], is referred to.

Title: Silencer for gaseous currents
IPC: F01N1/24
Filed: 1932-06-20
Abstract: 403,651. Silencers for gaseous currents. BURGESS LABORATORIES, Inc., C. F., Madison, Wisconsin, U.S.A.-(Assignees of Jack, W. A. ; Madison, Wisconsin, U.S.A.) June 20, 1932, No. 17411. Convention date, June 20, 1931. [Class 7 (ii).] A silencer for gaseous currents comprises a conduit which permits of a substantially unobstructed gas flow and has a wall of soundabsorbing material, and a side branch chamber in communication with said conduit. The branch chamber acts as an acoustic filter and is effective in removing low frequencies, the high frequencies being removed by the absorbing material. A casing 10, Fig. 1, has end openings 11, 12 either of which may be used as inlet and the other as outlet. A duct 13 extends from one of the openings and has a perforated wall surrounded by filling material of the kind mentioned in Specification 312,937, [Class 7 (ii), Internal-combustion engines, Arrangement &c. of], to act as an absorbing medium. Between the filling material and casing is the side branch chamber 17 connected with duct 13 by a passage 19. The diameter of duct 13 may vary with respect to opening 11. In a modification, the duct 13 is extended across the passage 19 to opening 11. In a further modification, Fig. 3, (not shown), the passage 19 is near the centre of the duct 13 thus giving branch chambers of unequal length. In Fig. 4, the duct 13 and its absorbing covering are longer than the casing 10, and one end projects into an extension 50 of the casing. In a modification, Fig. 5, (not shown), the duct 13 and wall 14 terminate short of the casing and an imperforate portion of duct 13 extends into an enlarged inlet pipe 11. In Fig. 6 the absorbing material 23 is arranged around the branch chamber 17. In Fig. 7, (not shown), an annular baffle is arranged around the entrance of passage 19 into chamber 17. In Fig. 8, a silencer as described in Specification 312,937 is modified by the insertion of a branch chamber 28 communicating with duct 13 by a passage 29 provided with a baffle 30. The walls of chamber 28 may be of foraminous material. In a modification, Fig. 9, (not shown) the branch chamber is situated at the end of the casing 10 adjacent the inlet 11. In Fig. 10, (not shown), applicable as an intake silencer wherein the gas flow and sound travel are in opposite directions, and a change of direction of gas flow is necessary, the branch chamber is of T-form surrounded by the absorbing material. The order in which the two types of silencing means are arranged with respect to the gas flow depends upon the characteristics of the sound to be silenced.

Title: Hydrogenation of carboxylic acids to alcohols
Inventor: CORR HUBERT
IPC: C07C29/149
Filed: 1961-05-16
Abstract: Catalysts for the hydrogenation of carboxylic acids to alcohols consist of a metal hydrogenation catalyst, the catalytic activity of which is impaired by sulphur, and which is prepared by sintering the metals which may be used are preferably copper, silver, manganese, iron, nickel and especially cobalt and may be supported on pumice, alumina, kieselguhr, silica gel, synthetic or natural silicates, porcelain or quartz.  The "sintering" is defined as heating the catalyst to a temperature which is not high enough to melt the catalyst but high enough to unite the particles in order to reduce the surface area and to improve the mechanical strength.  If desired the oxide of the metal may be sintered and then reduced to the metal.ALSO:Carboxylic acids are hydrogenated in the liquid phase to alcohols at elevated temperature and at atmospheric or increased pressure by means of hydrogen in the presence of a metal hydrogenation catalyst, the catalytic activity of which is impaired by sulphur, and which has been prepared by sintering. The term "prepared by sintering" is defined as heating the catalyst to a temperature which is not high enough to melt the catalyst but high enough to unite the particles to reduce the surface area and to improve the mechanical strength.  The process is particularly suitable for the hydrogenation of fatty acids with 3-20 carbon atoms, alkanoic dicarboxylic acids with 3-12 carbon atoms, aliphatic hydroxycarboxylic acids with 4-8 carbon atoms, aromatic hydroxycarboxylic acids with 7-9 carbon atoms, mononuclear aromatic monoor dicarboxylic acids and cycloalkanoic monoand dicarboxylic acids with 5 or 6 carbon atoms in the ring. The acids are preferably treated in aqueous or alcoholic solution at 150-300 DEG C  The preferred catalysts are copper, silver, manganese, iron, nickel and especially cobalt.  The catalyst may be sintered, if desired, in admixture with carrier substances such as pumice, alumina, kieselguhr, silica gel, silicates, porcelain or quartz, at temperatures which preferably lie only just below the melting-point of the metal used.  The oxides of the metals may be used as starting materials for the catalysts and in this case they are sintered and then reduced to the metal.  Examples are given of the conversion of (a) adipic acid to hexane-diol-(1,6); (b) glutaric acid to pentane-diol-(1,5); (c) the acid-containing product obtained by the oxidation of cyclohexane to a mixture of hexanediol-(1,6), pentanediol-(1,5) and butane-diol-(1,4); (d) propionic acid to n-propyl alcohol; (e) benzoic acid to benzyl alcohol; (f) cyclohexyl carboxylic acid to cyclohexyl carbinol; (g) salicylic acid to salicyl alcohol and (h) o -hydroxycaproic acid to hexanediol-(1,6).
