Filed: 1929-10-10
Abstract: 338,672. I. G. Farbenindustrie Akt.- Ges. Oct. 10, 1928, [Convention date]. Azo dyes are made by diazotizing the compounds produced by subjecting mono- or di-nitrobenzoylated diaminoarylsulphonic acids to a slight reduction, such as is required to convert an aromatic nitro compound into azo- or azoxycompound (see Specification 313,636) and coupling with a coupling component. In examples (1) the reduction product from 1-amino-4- (4<1>- nitrobenzoylamino)-benzene-2-sulphonic acid is diazotized and coupled with 1-p.sulphophenyl-3- methyl-5-pyrazolone; the product dyes cotton vivid golden-yellow, (2) the product from 1 : 4- di(4<1>-nitrobenzoylamino)-benzene-2-sulphonic acid is diazotized and coupled with 1-p-sulphophenyl- 3-methyl-3-pyrazolone, acetoacetic acid anilide (yellow lake), 1-phenyl-3-methyl-5-pyrazolone, a-gammadioxyquinoline, a-methylindole or 2-(m-amillobenzoylamino)-5-naphthol-7-sulphonic acid; the latter dyestuff when diazotized on the fibre and developed with 1-phenyl-3-methyl-5-pyrazolone or #-naphthol gives an orange red fast to washing.

Filed: 1970-06-26
Abstract: 1316864 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 26 June 1970 [27 June 1969] 31057/70 Heading G3P The injection timing of an internal combustion engine fitted with an electronically controlled fuel injection pump is controlled by a system comprising an electromagnetically actuated valve 10 for varying the pressure applied to an injection timing device 21 by an engine-driven feed-pump 18. An armature 13 varies the loading applied by a spring 11 to the control member 12 of the valve in accordance with the energizing current from a device 34 which also controls the injection pump through an output 36. The device 34 receives data representative of the load on the engine as well as an output signal from a position transducer 40 operated through a lever 25 from the device 21. Pressure applied to a piston 22 of the device is normally varied by the valve 10 which regulates the flow in a by-pass circuit for the pump. Rapid increases in pressure are, however, applied without delay through a check valve 20 while the effect of rapid decreases is delayed by a throttle 19. Leakage past the piston 22 is returned to the pump through a line 16.

Title: Improvements in and relating to electric motor control systems
IPC: B21B37/52
Filed: 1932-11-10
Abstract: 413,268. Maintaining defined speeds of several motors. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(General Electric Co. ; Schenectady, New York, U.S.A.) Nov. 10, 1932, No. 31814. [Class 38 (iii).] A control system for a cold strip rolling-mill having a plurality of roll stands 1, 2 and a separate motor for driving each stand, comprises a variable resistance R<2>-R<4> for initially adjusting the speed of one of the motors 14 to a predetermined rolling schedule, means for controlling the motor to maintain the tension of the strip 10 substantially constant, and loadresponsive means for rendering a portion of the resistance ineffective and the tension-controlling means effective. In one arrangement, Fig. 1, the rolls 11, 12 at the stands 1, 2 are driven by D.C. motors 13, 14 connected to the mains 15 through starting devices 17, 23. The speed of the motor 13 is adjusted by a variable resistance R<1> in the circuit of its field winding 18, and the speed of the motor 14 is initially adjusted to the desired rolling schedule by varying resistances R<2>, R<3> in the circuit of its field winding 24. The tension of the strip 10 is maintained constant by means of a vibrating regulator 27 adapted to cut in or out a resistance R<4> in the field circuit of the motor 14, the regulator being controlled in response to the load on the motor by a winding 30 connected through an adjustable resistance R<5> across a shunt 32 in the armature circuit of the motor. The resistances R<2>, R<3>, R<4> are simultaneously adjustable, but the resistance R<4> is short-circuited, during the initial speed adjustment of the motor 14, by a normally-closed contactor 36, which is in parallel with a normally-open contactor 37. The operating circuit of the contactors is controlled by load relays 38, 39, responsive to the load on the motors 13, 14 and by a contactor 41 which is energized by depressing the " regulating " push-button 42, and which has a hold on circuit through the back-contacts 41b and through the " non-regulating" push button 43. After the speeds of the motors have been adjusted to the predetermined schedule, the operator presses the button 42 and passes the strip through the rolls 11 and 12, the load relays 38, 39 thereupon operate to energize the contactors 36, 37 which respond to remove the shortcircuit from the resistance R<4> and to shortcircuit resistance R<3>, whereupon the speed of the motor 14 is automatically controlled through the resistance R<4> by the regulator 27 to maintain the desired degree of tension in the strip. As soon as the strip leaves the rolls 11, the load relay 39 opens, the contactors 36, 37 are de-energized, and the regulator is put out of service. In a modification, Fig. 3 (not shown), the resistance of a carbon pile in shunt with the resistance is varied automatically in response to the tension in the strip by means of a spring- controlled roller which transmits the pressure to the carbon pile through electrical motion transmitting and receiving devices.
