Title: Visual display system
IPC: G09G5/28
Filed: 1972-04-28
Abstract: 1391951 Cathode-ray tube alphanumeric display RAYTHEON CO 28 April 1972 [14 May 1971] 19936/72 Heading H4T A CRT display arrangement for alphanumeric characters using a dot-matrix bright-up of a raster scan obtains improved character representations by permitting intermediate horizontal positioning of the dots of the matrix under control of a control bit. Thus a 7 x 7 dot array representation is effectively increased to a 7 x 14 dot array. Each row of characters to be displayed is transferred to a recirculating store where it remains for 9 line scans (7+2 inter row lines), and each character controls (together with the line count), the read-out of the video information, including the control bit. The intermediate positioning of the dots of a raster row is obtained by using the control bit to switch in a suitable delay. Fig. 10 (not shown) illustrates the arrangement schematically.

Title: Improvements in or relating to piperazine
IPC: C07D295/023
Filed: 1950-08-11
Abstract: Piperazine is isolated from the mixture obtained in the manufacture of commercial ethylene amines by cooling it to 0 DEG  to 10 DEG  C. in the presence of piperazine seed crystals until crystallization ceases and then collecting the piperazine crystals.  The residual liquid may then be distilled and the fraction boiling between 145 DEG and 180 DEG  C. subjected to crystallization as before; the liquid obtained after removing the piperazine crystals is again returned to the distillation operation.  The original ethylene amine mixture or the liquid from the initial crystallization may be concentrated to a 20 to 40 per cent piperazine content by distillation before subjecting it to crystallization.  Piperazine hexahydrate may be obtained by adding water to the original mixture or concentrate, but the temperature is not taken sufficiently low to cause separation of ice.

Title: Improvements in Static Invertor Control Circuits
Inventor: AINSWORTH JOHN DESMOND
IPC: H02M7/00
Filed: 1966-05-06
Abstract: 1,170,247. Inverting. ENGLISH ELECTRIC CO. Ltd. 4 May, 1967 [6 May, 1966], No. 20276/66. Heading H2F. In an inverter, e.g. for a HVDC transmission system, firing pulses for the mercury pool rectifiers or thyristors are derived from the sum of the current I d  in the D.C. circuit, the rate of change of current and the A.C. voltage after phase advance. As shown, the A.C. voltage from an auxiliary six-phase transformer (Fig. 1, not shown) is phase advanced at 16 by 21 degrees before being superimposed on a voltage derived from a D.C. current transformer 19 and a further voltage proportional to the rate of change of current, derived from a gappedcore current transformer 20. Diode D1 removes the negative pulse. A limiting amplifies Trl is thus turned on and off at angles which are a function of I d , giving a square pulse which is differentiated at 18 to provide firing pulses for one of the six-phase rectifiers (Fig. 1, not shown). Other control circuits 14, fed from other phases of an auxiliary transformer provide phasedisplaced pulses for the other main converting elements. The system maintains constant current Id in the D.C. line and tends to result in substantially constant de-ionization margin angle when the A.C. parameters of the system vary.

Patent GB-221227-A (GB)
IPC: C07C37/00
Filed: 1924-08-30
Abstract: Thymol is prepared from p-cymene by first nitrating it to form 2-nitrocymene, reducing this to azoxycymene or cymylhydroxylamine which contain an oxygen atom attached to the nitrogen atom, isomerizing the product with an acid to cause the oxygen atom to migrate as a hydroxy group into the ortho or para position to the nitrogen-containing group, and subsequently eliminating the latter group by diazotization and reduction, after, in the case of the azoxycymene isomerization product, splitting it by reduction. According to the examples, (1) 2-nitrocymene is reduced electrolytically in alkaline suspension, using nickel cathodes or with sodium in alcoholic solution to produce azoxycymene, which is separated and heated with concentrated sulphuric acid; the solution of the resulting mixture of o- and p-oxyazocymenes is neutralized and sodium hydrosulphite added, whereby 2-cymidine and o- and p-aminothymols are produced; the bases are extracted with benzene, separated by vacuum distillation, and the aminothymols worked up into thymol by eliminating the amino group in any known way; (2) an alcoholic solution of 2-nitrocymene saturated with calcium chloride is reduced with zinc dust, the cymylhydroxylamine heated with concentated sulphuric acid and diluted with sodium bisulphite solution, and the resulting p-aminothymol dissolved in hydrochloric acid and worked up as before.
