Abstract: 1,019,663. Hydraulic torque converters. S.R.M. HYDROMAKINAK A.B. July 24, 1962 [Aug. 8, 1961], No. 28386/62. Heading F2C. [Also in Division G3] An hydrodynamic torque converter comprises a centrifugal pump driving a turbine in which the blades of the pump are adjustable through a servomotor. The drive shaft 12, Fig. 2 (not shown), of the pump rotates a blade ring 14 carrying the blades 18 of the pump. Each blade is mounted on a pivot 84 to which is fixed a socket 86. A further socket 88 is carried by the socket 86, these two sockets being relatively non-rotatable. A key 90 prevents axial movement between the parts 84, 86, 88 but the socket 88 is capable of limited radial movement relative to the socket 86 and pivot 84. The outer side of the socket 88 is provided with helical gears which engage helical teeth on a piston member 96 such that axial movement of the piston rotates the blades 18. The movement of the piston is controlled by a valve 104 movable axial on the shaft 12 by a setting lever 106. A fluid supply, fed by a gear pump actuated by the shaft 12, is led to the space 70 in the hollow shaft and by ports 108 to a groove 110, in the valve 104, and to ports 112. The piston 96 has a cylindrical hub 100 having passageways 124, 126 leading from the opposite sides of the piston to grooves 114, 116 separated by a wall portion 115. When the valve 104 is moved axially by the lever the supply at port 112 is. fed to one side of the piston while the other is opened to exhaust thus causing movement of the piston until the wall 115 again closes the port 112. If at any time the blades rotate, the piston is moved to open the supply and exhaust as above to return the blades to their original setting.

Title: Process for the manufacture of vat dyestuffs of the anthraquinone series
IPC: C09B1/38
Filed: 1927-10-26
Abstract: 305,082. Carpmael, A., (I, G. Farbenindustrie Akt.-Ges.). Oct. 26, 1927. Samples furnished. Anthraquinone vat dyes are obtained by the action of sulphuric acid at a relatively low temperature on a 1: 1'- or 2 : 1<1>-dianthraquinonylamine containing at least one acridone ring in the 3(CO)-4(NH)-position, and, in addition, at least one acylamino group, with or without other substituents. Whenever necessary the products are oxidized, for example with nitrous acid. The products are believed to be carbazoles, ring closure apparently taking place in the 2 : 2<1>- or 1 : 21-positions. In an example, the dianthraquinonylamine obtained by condensing 4-amino- 1 : 2-anthraquinoneacridone with 1-benzoylamino- 5-chloranthraquinone in molecular proportions is treated with concentrated sulphuric acid at 15‹- 20‹ C. ; a green precipitate is formed which becomes olive-brown on adding sodium nitrite and heating to 60‹ C. The product dyes cotton in fast olive-brown shades, whereas the starting- material dyes it greenish-grey. The corresponding dianthraquinonylamine from 1-benzoylamino- 4-chloranthraquinone dyes cotton in greyishgreen shades, and when treated with sulphuric acid and nitrite yields a reddish-grey vat dye. Specification 29352/10 is referred to.

[Also in Group XXX] An endless conveyer band 1 carrying a stream of unwrapped tobacco is driven by a driving roller 21, Fig. 4, and has its speed alternately increased or decreased by guide rollers 22, 23 arranged on opposite sides of the roller 21 and carried by a pivoted lever 24 oscillated by a cam 27 so that the rollers 22, 23 are alternately raised and lowered. The stream of tobacco is delivered through a guide 2, Fig. 1, on to a paper web 4 carried by a conveyer 5 running at the higher speed of the conveyer 1 and is cut by a knife 6, whereupon the speed of the conveyer 1 is immediately reduced by the action of the cam 27 to form a gap between the cut length of tobacco carried forward by the web 4 and the uncut stream, into which gap a mouthpiece stub is subsequently inserted by a wheel 9, as described in Specification 709,197, to form a composite filler. After the formation of the gap, the speed of the conveyer 1 is again increased up to that of the conveyer 5 to deliver the uncut filler on to the web 4 substantially at the speed of the web until the next cutting operation. A roller 7 rotating at the speed of the web 4 engages the cut portions and ensures that they move with the web and a shoe 12 beyond the stub insertion wheel 9 presses the stubs on to the web, the under surface of the shoe 12 being either flat or, as in Fig. 3, provided with two ribs 19, 20. A rotatable disc 14 has sets of fingers 15, 16, 17, which move slightly faster than the web 4 and engage the tobacco just behind a stub to ensure abutment between the tobacco and stub, the composite filler finally passing to a wrapping mechanism.
