Title: Purification of guanidine nitrate
Filed: 1943-11-04
Abstract: In the method of manufacturing guanidine nitrate by fusing ammonium nitrate and dicyandiamide purification, steps are introduced for removing melamine and iron impurities, the former by precipitating melamine nitrate from solution with nitric acid, and the latter by converting any ferrous iron to ferric by aeration and precipitating with an alkali.  These steps form the basis for a cyclic operation as follows: the ammonium nitrate, dicyandiamide fusion product is dissolved in water or the mother liquor from a previous cycle.  Iron is removed from the solution in the above manner and guanidine nitrate crystallized out.  The mother liquor is treated with nitric acid to remove melamine and then either returned to the cycle as a solvent for the ammonium nitrate, dicyandiamide fusion product, or evaporated to dryness to produce a crude solid ammonium nitrate which may then be added direct to the fusion pot.

Title: Regulated power supply for electric motors
IPC: H02P7/288
Filed: 1959-06-01
Abstract: 900,088. Control of D.C. motors. MINNESOTA MINING & MANUFACTURING CO. June 1, 1959 [June 17, 1958], No. 18647/59. Class 38 (3). The speed of a separately excited D.C. motor is stabilized by supplying the armature through an emitter follower transistor, and the transistor is rendered fully conductive to protect it against over-voltage at starting when the back e.m.f. is zero. In one embodiment, Fig. 1, the armature 1 of the motor forms the emitter load of transistor 6, the base bias of which is derived partly from a potential divider 11, 12 so as to respond to the voltage drop across the armature, and partly from the transistor 7 which amplifies the voltage across a resistor 9 in series with transistor 6 so as to decrease the impedance of transistor 6 with increasing motor current. By suitably proportioning the circuits, the change in voltage drop across transistor 6 can be made to compensate for change in armature voltage drop with varying load. At starting, if the base/collector voltage of transistor 6 is higher than the reverse base/collector voltage of transistor 7, the latter junction conducts and renders transistor 6 fully conductive. In a modification, Fig. 2 (not shown), a Zener diode is connected between the collector and base of transistor 6. In another modification, Fig. 3 (not shown), not only are the polarity types of transistor reversed, but the transistor 7 is biased by diodes so as to only become effective when the motor current is above normal.

Abstract: 1,256,453. Selective control of printers. CREED & CO. Ltd. 21 April, 1970, No. 18968/70. Heading G4H.  In a non-percussive printer of the kind in which each character is formed as a pattern of dots, all the characters of a line being printed at the same time by a line or recording heads R1-R80 &c. energizable in a predetermined order by a sequence generator through a switching network which is arranged, to switch current from one head.to another of the line of recording heads the order of switching is such that adjacent heads, are never energized consecutively In ferrographic printers where each head produces a magnetic field, the decaying field in one head may interfere, with. the growing field in the adjacent head when the printer is operated at high speed. Similar effects may occur in thermographic printers. Each character is printed by a group of ten heads, e.g. R1-R10 certain ones of which are energized as the paper moves under the heads to form dots in appropriate ones of a 10 x 15 array of positions. The ten heads R1- R10 are connected in parallel with corresponding heads R41-R50, &c., heads R11-R20 are connected with heads R51-R60, &c. and so on. Switches D1-D10 control heads R1-R10 and those connected in parallel with them. Switches D1-D10 are connected together to. switch G1, switches D11-D20 are connected to switch G2 and so on. Switches G1 and G3 are connected together to switch H1 and switches G2 and G4 are connected to switch H2. On the other side of the heads; the first forty heads are connected together to switch G5, the next forty to switch G6 and so on. To operate head R1 switches H1, G1, H3, G5 and D1. are closed for a, time T sufficient to allow effective printing. At the end of this time switch H1 opens. This switch is a fast acting switch, capable of operating at least four times as fast as the G or D switches. Switches G1 and D1 also open but somewhat later the current being broken by the fast switch H1. While head R1 was operating switch elements G2 and D11 (if R11 is to operate) are closed, preparing a path through head R11. As soon as switch H1 opens, switch H2 closes for the necessary period T. Next, head R21 is operated in the same way and then head R31, so that, if they are required, four dots are printed in the first four columns. The process is then repeated to operate heads R2, R12 &c. and so on until all the necessary heads in the first four groups are operated.. The next 4 groups are then operated, switch G6 having closed sometime before and switch H4 closing as switch H3 opens. This process continues until all the heads are operated. Apart from preventing interference, the switching arrangement allows a small number, of fast switches to perform the high-speed switching for a large number of heads.
