Patent GB-318247-A (GB)
Abstract: 318,247. Akt.-Ges. Brown, Boveri, et Cie. Aug. 31, 1928, [Convention date]. Machines with vapour or like rectifiers in place of commutators.-In a device for commutating continuous-current in an .armature winding, the feeding points of the winding are connected to the continuous-current source through valves or arcs without the use of mechanical commutators, and an auxiliary alternating current is superimposed upon the current in the valve anodes having a frequency greater than the basic frequency of the machine multiplied by half the number of anodes, parallel working anodes counting as a single anode, for the purpose of bringing the branch currents in the valves periodically to zero, the alternating current being supplied to the short-circuited parts of the working winding by transformer action from a primary winding stationary relatively to the field system and coaxial with the commutating parts of the working winding. As shown, a commutator c and slip rings d, e are rigidly connected with the rotating field system a, b. A drum armature winding f is divided into eight equal parts at the points I - - VIII and these points are connected to double valves g<1> - - g<8>. The controlling grids of diametrically opposite valves are connected together and to contact brushes on the commutator c. The commutator comprises two contact segments x, y respectively connected to the slip rings d, e. The electrodes of the double valves which are not connected to the armature winding are connected to the bus-bars h, and batteries B<1>, B<2> are connected across the slip rings and bus-bars. An auxiliary winding W arranged coaxially with the commutating portion of the working winding f is supplied with alternating-current. The alternating current in the winding W induces by transformer action a current in the winding groups short-circuited during commutation which periodically brings the resultant current in the valves in the commutating circuit to zero. In the position shown, the valves g<2>, g<3> act as inlet valves and the valves g<6>, g' as outlet valves since the appropriate halves are rendered conducting by the connection of their grids with the positive terminal of the battery B<1> through the commutator segment x and slip-ring d. Since the machine is bipolar, one revolution corresponds to one period of the basic frequency so that the auxiliary alternating current must have a frequency exceeding four times the basic frequency.

Title: Manufacture of vat dyestuffs of the anthraquinone series
Filed: 1948-12-09
Abstract: Benzoic acid-3-sulphomorpholide is obtained by condensation of benzoic acid-3-sulphochloride and morpholine in water.  Benzoic acid-3-dimethylsulphonamide and its 4-chlor-derivative are prepared similarly from the corresponding sulphochloride and dimethylamine.ALSO:Dyes are made by acylating a 1-acylamino-4-aminoanthraquinone and so choosing the starting materials that one of the two acyl groups present in the product is the residue of a benzene - 1 - carboxylic acid - 3 - dialkylsulphonamide or a benzene-1-carboxylic acid-3-dialkylene-sulphonamide in which the alkylene residues are interconnected to form a ring, and the other is the residue of an aromatic carboxylic acid of the benzene series free from sulphonamido groups, a substituent being present in the nucleus of the last-mentioned residue or in the anthraquinone nucleus.  The two alkylene radicals of the sulphonamide group may be joined by methylene or oxygen. Substituents specified are halogen, cyano, alkyl, alkoxy, alkylsulphone, or arylsulphone.  The acylation may be carried out in the usual solvents, and the products or their leucosulphuric ester salts may be used for dyeing or printing wool, leather, silk, linen, cotton, artificial silk, regenerated cellulose. In examples: (1) benzoic acid-3-sulphomorpholide is converted to its acid chloride and the latter is reacted with 1-benzoylamino- (or p-methoxybenzoylamino-) 4-amino-6-chloranthraquinone; (2) benzoic acid-3-dimethylsulphonamide is converted to its acid chloride and the latter is reacted with 1-benzoylamino-4-amino-6-chloranthraquinone or with 1-(41-chlorobenzoylamino) - 4 - aminoanthraquinone; (3) 4 - chlorobenzoic acid-3-dimethylsulphonamide is converted to its acid chloride and the latter is reacted with 1 - amino - - (31 - chlorobenzoylamino)-anthraquinone; (4) benzoyl chloride is reacted with 1-amino-4-(31-dimethylsulphonamido - benzoylamino) - 7 - chloranthraquinone.  An example of dyeing cotton is also given. Other suitable starting materials as indicated above are listed.

Title: Automatic optimum power seeking control system
IPC: F02D9/00
Filed: 1969-06-26
Abstract: 1280356 Timing ignition OPTIMIZER CONTROL CORP 26 June 1969 [12 Aug 1968] 32469/69 Heading F1B [Also in Division G3] The optimum setting for a variable which influences the output of a power producing machine is automatically obtained by an arrangement in which the setting is oscillated about a zero position which is adjusted by a fluid-pressure operated device responsive to the power output so as to maximize said output. The invention is applied to a spark ignition I.C. engine 10, the distributor 12 of which is continuously oscillated (about 100 times per minute) by a connection 15. As shown, this is coupled to a hydraulic piston 22 to which fluid-pressure from 19 is applied to opposite sides alternately by an electromagnetic valve 21, which is energized via a slip ring type switch 17b, 17c driven by auxiliary means. The fluid outlet at 32 is controlled by a second electromagnetic valve 30 which opens or restricts either passage 28 or 34 and is controlled by a logic circuit 37 having inputs from a second slip ring switch.17c, 17d and an accelerometer or torque transducer 35 on the output shaft of the engine. The logic circuit determines whether advance or retard of the ignition is associated with acceleration or deceleration and the system stabilizes when both advance and retard produce deceleration. The slip rings 17a, 17b are offset to provide a time delay equal to the response time of the system. The slip rings may be replaced by an electronic generator of square or sine waves. In an alternative embodiment, Fig. 4 (not shown), the inlet, only, to the piston 22 is controlled by an electromagnetic spool valve energized to admit fluid for a greater time on one side than the other, or equally, by selection of either of three rectangular wave trains which have respectively longer positive than negative excursions, or vice versa, or equal periods; the selection is made by a logic circuit which receives signals from the accelerometer and from a magnetic pickup which senses the oscillations of the rod of piston 22. In a further alternative, Fig. 5 (not shown), the system is pneumatic and uses the intake manifold vacuum. The actuator comprises a diaphragm, the pressure on one side of which is controlled by selection of wave trains as in Fig. 4. The system may be disabled if other variables such as engine speed and vacuum are beyond prescribed limits.

Title: Fluid pressure converting relays
IPC: G05B11/44
Filed: 1949-12-19
Abstract: 677,458. Fluid-pressure servomotor-control systems. PUTMAN, R. E. J., SCHIPPERS, J. F., and GORDON & CO., Ltd., J. Aug. 30, 1950 [Dec. 19, 1949], No. 32548/49. Class 135. A relay for converting a received control pressure obeying one law into an outlet pressure obeying another so that there is a definite relationship between the control and outlet pressures, comprises a piston 22, Fig. 1, positioned by the control pressure and operating a pilot valve 43, supplying the outlet pressure, through linkage including a cam plate 35. The control pressure is received through a port 19 and acts on diaphragms 15, 16, Fig. 4, the latter having the larger area, to move a block 11 to the right and open a valve 7. Fluid from a pipe 6 leading to a constant pressure source then flows into a chamber 9 and through a pipe 18 to move the piston 22 until a tension spring 26 moves the block to close the valve. The piston moves a link 31 having, at one end, a roller 34 engaging the cam plate 35, and being connected at the other to one arm of a bellcrank 32 pivoted at 33. The other arm of the bellcrank engages a spring 38 to move a block 39, supported by a diaphragm 40, and open the pilot valve 43 which admits fluid from the constant pressure source to a chamber 47 and an outlet 46. The pressure in the chamber acts against the spring 38 to close the valve 43 when the requisite outlet pressure is reached. An increase in the control pressure will cause an increased outlet pressure, whilst a decreased central pressure permits the spring 26 to move block 11 to open a valve 8 connecting chamber 9 to exhaust via passages 10, 21 and 20. Piston 22 then moves to the right until the block 11 closes the valve 8, and through link 31 and bell-crank 32 decreases the tension of spring 38 to permit block 39 to open a valve 42 and reduce the outlet pressure. The cam plate 35 is calibrated by fixing a blank in its place and replacing the roller 34 by a disc of equal diameter which abuts one side of the blank. Control pressures of known values and at various points throughout a desired range are then applied to the port 19, and for each value the spring 38 is moved by a knob 54, which engages by a screw 48, member 51 and pin and slot 53, 52, the bell-crank 32, to produce a desired pressure in the outlet 46, and the position of the disc is marked on the blank. The blank is then removed and the cam contour cut according to the markings.
