Title: Improvements in keto-sulphones and process of preparing them
IPC: C07C317/14
Filed: 1945-09-18
Abstract: Dissymetric keto-sulphones useful as intestinal antiseptics are prepared by reacting a benzene sulphinic acid, substituted in the paraposition of the benzene ring by an amino radical or a nitrogen-containing radical convertible into an amino radical, with an unsaturated ketone containing at least one double bond in a b -position to the keto group.  The products have the general formula <FORM:0599470/IV/1> in which R is an amino group or a group convertible into an amino group, R1, R2 and R3 are alkyl, cycloalkyl, aryl, aralkyl or aralkenyl radicals, and R2 and R3 may also be hydrogen.  Examples of R1, R2 and R3 are methyl, ethyl, higher alkyl, cyclopentyl, cyclohexyl, cyclohexenyl, propenyl, butenyl, phenyl, p-tolyl, p-chlorphenyl, naphthyl, benzyl, phenylethyl and phenylethenyl.  The following examples are given: (1) p-aminobenzene sulphinic acid and mesityl oxide are refluxed in ethyl alcohol to give p-aminophenyl-(1,1-dimethyl-2-acetylethyl)-sulphone; (2) p-aminobenzene sulphinic acid and benzal acetone are refluxed in ethyl alcohol to give p-aminophenyl-(1-phenyl-2-acetylethyl)-sulphone; (3) and (4) p-nitrobenzene sulphinic acid and benzal acetone are refluxed in ethyl alcohol and the product hydrogenated in the presence of platinum oxide catalyst to give p-aminophenyl-(1-phenyl-2-acetylethyl)-sulphone; (5) p-acetaminophenyl(1-phenyl-2-acetylethyl)-sulphone is obtained from p-acetaminobenzene sulphinic acid and benzal-acetone, the N-acetyl group being then split off by means of sodium carbonate solution; (6) p-aminophenyl-(1-phenyl-2-benzoylethyl)-sulphone is obtained from p-aminobenzene sulphinic acid and benzal-acetophenone; (7) p-aminophenyl-(1-phenyl-2-cinnamoylethyl)-sulphone is obtained from p-aminobenzene sulphinic acid and dibenzal-acetone.  The Specification as open to inspection under Sect. 91 refers also to the preparation of compounds of the formula <FORM:0599470/IV/2> in which R4 has the same meaning as R2 and R3, and R1, R2, R3 and R4 may also be an alkenyl radical.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in fluid operated change speed gears
IPC: F16H47/08
Filed: 1923-10-01
Abstract: 218,889. Schneider, H. Oct. 1, 1923. Clutches and speed-varying mechanism. - A fluid-operated change speed gear comprises in combination a driven pump and a driving pump of the rotary type having outwardly sliding vanes, shown diagrammatically at 1 and 2 in Fig. 1, one arranged within the other, passages 7 or 8 in the rotor of the outer pump 1 to establish connection between the working chambers of the pumps without the interposition of stationary parts, and means for altering the eccentricity of one of the pump rotors to vary the speed ratio. Small bores 12 and slots 13 keep the radial slots in which the vanes 4, 5 slide, always filled with fluid. Semicircular grooves 25, 26 in the surrounding casing 3 serve to equalize the pressure in the various pump chambers. In the form shown in Figs. 4 to 7, the inner pump 40 is connected by spur gearing 33, 32 to a driving shaft 31, and the outer pump 50 is similarly connected by spur gearing 53, 56 to a driven shaft 60. The vanes of the pumps are guided by circular grooves in the end members embracing them. The pump chambers are kept filled with fluid by a small gear pump 63, which is driven by a spur pinion 62 in mesh with the spur wheel 33, and sucks any oil that leaks into the outer casing 37 and forces this oil back to the pump chambers through a double beat valve 70 adapted to open automatically to the suction side of the pumps. The semicircular grooves 57, 58 serving to equalize the pressure in the various pump chambers are connected to a safety valve 181. The ends of the shaft of the inner pump 40 are carried by rocking arms 71, 72 mourted on spindles 74, 75 and connected by tie-rods 76, 77 to eccentric pins 78, 79 on a shaft 80, which can be rocked by a handle 73 to raise or lower the pump 40 to vary its eccentricity within the outer pump, and thereby vary the speed ratio. In a. modification, the eccentricity of the outer pump is varied by raising or lowering the' casing surrounding it. In these arrangements, when the adjustable pump is in the neutral central position. no speed is transmitted to the driven shaft; and by an adjustment of the pump to an eccentric position either way, the driven shaft may be rotated in one direction or the other at various speeds up to a certain maximum. In another modification. Fig. 10, the driving shaft 260 and the driven shaft 275 are connected to tl e main bevel wheels 271, 273 of a differential gear, the carrier 268 of the planet, pinions 272 being geared to one pump 264, and the other pump 26@ geared to the driving shaft. With this arrangement. when the adjustable pump is in the neutral central position, the speed is transmitted to the driven shaft direct through the differential gear. and adjustment of the pump to an eccentric position either way varies the speed up or down.
