Patent GB-1264218-A (GB)
IPC: A61K31/475
Filed: 1969-06-04
Abstract: 1,264,218. Preparing eburnamonine. L. OLIVIER. 4 June, 1969 [25 June, 1968], No. 28232/ 69. Heading ASB. A process for preparing eburnamonine comprises forming, from seeds of Hunteria eburnea, an alkaloidic extract in an organic solvent, treating this extract, if desired, after removal of the solvent, with an acidic aqueous solution, making the aqueous phase alkaline, collecting the resulting total alkaloids precipitate, at least partially dissolving the latter in an organic solvent having a boiling point not above 120‹C. and precipitating the eburnamonine. The seeds are suitably extracted with an alcohol which is then removed by distillation and the extract may then be dissolved in a water-immiscible organic solvent prior to acid treatment. Prior to extraction the seeds may be treated with an alkaline material such as a carbonate, an inorganic base or ammonia. The eburnamonine may be purified by crystallisation or chromatography, e.g. on alumina.

Abstract: 1,264,304. Knitting. BENTLEY MACHINE DEVELOPMENT CO. Ltd. 3 Dec., 1969 [6 Dec., 1968], No. 57963/68. Headings D1C and D1K. A knitted tube, e.g. stocking is closed by a double welt constricted by a plurality of loops of yarn 16 a-f each partly encircling the welt fold, and together wholly encircling it. The encirling loops are obtained by directing all needles to an inactive level, and then raising different small arcs 15 of needles at succeeding courses. This causes yarn to extend from the trailing needle 15a of the group, around the tube 19 to constrict it, e.g. 16b and then to rejoin the first of the active needles 17. The yarn is then knit again and at a subsequent arc where the proceedure is repeated to form the next loop 16c. The yarn is laid in or knitted along the intermediate arc 18. When sufficient loops have been formed the held welt loops are returned to the needles. The tube is completely closed when it is drawn onto a form, which tightens the loops.

Abstract: 1,266,794. Valves. DANFOSS A.S. 12 June, 1969 [19 June, 1968], No. 29845/69. Heading F2V. A flow regulating valve comprises a resilient disc 2 up stream of a rigid perforated plate 1 provided with projections 6 which space the disc from the plate.

Abstract: 1290149 Transistor pulse circuits SONY CORP 23 Oct 1969 [23 Oct 1968 31 July 1969] 52006/69 Heading H3T .  Field effect transistors M1, M2, M3 are arranged substantially as shown and supplied with separate clock pulses on lines t 1  and t 2 , so that if the FET's are N-channel enhancement types requiring a positive gate pulse to make them conduct, positive clock pulses from t 1  (CP1, Fig. 2, not shown) pass through M2 to charge a capacitance C which holds the charge between clock pulses only if an input (S1) to. M1 at T 1  is negative to prevent M1 from discharging C. The signal (S2) on C is thus the inverse of the input (S1) and is gated by M3, when the next t 2  clock pulse (CP2) occurs, to the point X2 (S3). A similar arrangement of FET's M4, M5, M6 perform a similar inversion and delay function, and the output (S5) at T 2  is the same as the input at T 1  delayed by one clock pulse period. The clock pulse periods of t 1  and t 2  need not be the same, and the output signal (S5) is consequently varied (Fig. 2, B<SP>1</SP> to G<SP>1</SP>, not shown). In an alternative embodiment (Fig. 3, not shown) the FET M4 of Fig. 1 is effectively removed to the input to supply T 1  to M1 gate, the clock connections remaining unchanged. Operation is similar basically to that for Fig. 1. A bi-stable circuit using P-channel FET's and consequently using the opposite polarity clock and input pulses to those of Fig. 1, is formed from the basic Fig. 1 circuit by connecting across FET's M5 and M6 (M8, M11, Fig. 5, not shown) a third FET (M12) receiving a "set" signal (S) at its gate; and by connecting in series with M5 (M8) a feedback FET (M9) whose gate is connected to the output T 2 . The T 1  input is used as a "reset" input (R), and the T 2  output is derived from M4 (M10) by a third invert and delay circuit (M13, M14, M15). A negative "set" signal causes the normally positive level of the clock pulse source (CP2) at t 2  to be transmitted (by M12) to the source drain path of the FET (M10) feeding the said third circuit, the FET (M13) of which is thus held off. The clock source (CP1) at t 1  thus charges (through M14) a capacitance (C<SP>111</SP>) to a negative level and this is passed (through M15) to the output T 2 . This negative level at T 2  holds the feedback FET (M9) on, and if its series FET (M8) is also on (due to a negative gate voltage generated by CP 1 in the absence of an R input signal which would discharge C), then the normally positive level of CP2 is maintained at the drain of the "set" FET (M12) even when the set signal ends. A reset signal R turns on its FET (M1) to discharge C and -break the feedback path (by turning off M8), and the next CP1 pulse and the subsequent CP2 pulse reset the output T 2  (Fig. 6, not shown).

Abstract: 1353556 Fluid regulation INSTITUT FIZIKI AKADEMII NAUK LATVIISKOI SSR 15 Nov 1971 52983/71 Heading G3H The flow-rate of an electrically conductive liquid flowing between the poles of a magnetic system is controlled by establishing along the liquid flow, regions having different values of induced e.m.f. In the apparatus shown in Fig. 1, the liquid passes along a pipe 1 disposed between two toothed poles, the teeth of the poles being aligned so that the voltage induced in the liquid between two teeth has a value different from that induced in the liquid between two inter-teeth slots. Large circulating currents are set up in the liquid It is stated that these currents cause substantial heat loss, thereby affecting the flow-rate. Adjustment of the flux density alters the flow-rate. One of the poles may be constructed to permit adjustment of the depth of the inter-teeth slots, Fig. 2 (not shown). Windings may be placed in the slots, variation of the winding current varying the liquid flow-rate. Control of the flow-rate may be achieved by establishing along the flow, regions having different velocity. Thus in the apparatus of Fig.4., the duct 10 containing the liquid has alternating widenings and contractions. Where the liquid is metal, the widenings are preferably filled with inserts of the same metal, Fig. 6 (not shown).

In a further modification, Fig. 8 (not shown), the duct for the liquid is of rectangular crosssection, the two walls parallel to the poles of the magnetic system being of electrically conductive material and the remaining two walls having alternate conductive and non-conductive segments.
