As described, the invention is applicable to a three-phase bridge for HVDC power transmission. Each thyristor 2a ... 2n may be replaced by several parallel-connected thyristors. In the event of overvoltage, the avalanche diodes 4a ... 5n become conductive, the current being monitored by transformer 9 the output of which is rectified at 13 ... 16 and integrated at 17. If the integral is sufficient to break down device 22, capacitor 25 discharges into the gate of thyristor 20 so that the resulting pulse from transformer 29 triggers the surge arrestor 8. Further avalanche diodes 38a ... 39m may be included where the reverse voltage amplitude exceeds the forward voltage amplitude. In Fig. 2 (not shown), an uncontrolled surge arrestor is connected in series with arrestor 8, the junction between the arrestors being connected to a point on the string of thyristors by means of a resistor.

Title: Improved process and apparatus for degreasing fibrous materials
IPC: D06F43/08
Filed: 1927-11-23
Abstract: 311,825. Imperial Chemical Industries, Ltd., and Savage, J. Nov. 23, 1927. Recovering fats and oils from cotton waste and fibrous materials. - Oily cotton waste or other fibrous material is degreased by passing upwardly through it the vapour of a solvent, condensing the solvent above the waste and allowing it to fall back thereon at a temperature but little below its boiling point, withdrawing the extract, removing residual solvent and the cotton waste, and returning the extract to the extractor and distilling off the solvent. For example, after oily rags have been placed on a grid 2 in a chamber 1, and the air in the chamber displaced by solvent vapour obtained by passing steam through coils 3 immersed in liauid solvent admitted through a valve 11, water is passed through condensers 5, 6 so that the vapour is condensed and falls uniformly distributed over the rags. When the gauge 20 shows a fall in pressure, owing to the saturation of the solvent, the extract is run through a valve 24 and a pipe 12 to a reservoir 13. More solvent is admitted to the extractor from the reservoir 10 and the process repeated. Residual solvent is then removed by steam admitted through a pipe 25, the vapours passing by a pipe 16 to a condenser 15 from which the solvent flows to a water-separator 18, and, by a pipe 19, to the reservoir 10. The degreased rags are dried by air blown in through the pipe 25, and are then removed. The extract in the reservoir 13 is returned to the extractor 1 by filling the extractor with steam, condensing it by cooling coils 4, 5, 6, and opening the valve 24. The solvent is then distilled off by steam from the pipe 25 or by heating the coil 3, and passed to the condenser 15, waterseparator 18, and reservoir 10. The extracted oil is removed through a tap 23.

Hydraulic control means for a vehicle propelled by a hydraulic motor 110, Fig. 1, supplied by an engine-driven pump 113 which also supplies one or more double acting rams 111, 112 comprises a first valve 15 for directing fluid from the pump outlet 118 to the motor 110 and returning fluid therefrom to the pump inlet 114, a further valve or valves 16, 17 for similarly directing fluid to and from the or each ram 111, 112 and a non- return valve 121 disposed between the pump inlet 114 and said further valve or valves 16, 17 for preventing fluid-flow from the pump inlet to said further valve or valves e. g., as might occur due to an increase in pump inlet pressure due to a reduction of delivery to the motor 110 whilst the latter exerts a braking effect on the vehicle. The valves 15-17 are of the spool kind arranged in a single body 11, Fig. 2, having an inlet port 12 open to the pump outlet 118, a first outlet port 13 by which valve 15 is connected by a line 119 to the pump inlet 114 and a second outlet port 14 by which valves 16, 17 are connected by a line 120 to the pump inlet 114 at a point upstream of the non-return valve 121 which is in the delivery line of a booster pump 116.

Title: Apparatus for treating textile materials
IPC: H02P5/48
Filed: 1954-11-01
Abstract: 781,269. Feeding webs. SUCKER GES., GEB, Nov. 1, 1954 [Nov. 3, 1953], No. 31562/54. Class 100(1) [Also in Group XXXVIII] An apparatus, for treating a textile web 1 or band of threads in which the web or band of threads passes between input rollers 2 and output rollers 3 disposed respectively at the beginning and end of a treatment zone 4, has control means for automatically correcting deviations arising in the speed ratio of the drive to the rollers from a required constant value. The rollers 3 are driven by a motor 5 through gearing, while the rollers 2 are driven, at a different speed, by the motor 5 through a variable speed gear 6. The variable speed gear 6 is controlled by a mechanism 8 having a variable ratio gear 9 comprising opposed cones and an intermediate wheel 28 and driven by the motor 5. The speed ratio of the gear 6 is varied by a threaded spindle 22 driven by a motor 7. In operation, inadvertent deviations from the required setting of the variable speed gear 6 cause a difference in speed between pinions 11 and 12 of a differential gear 10, the pinions being driven respectively in synchronism with the rollers 2 and 3; the difference in speed causes movement of a lever 13 carrying a contact 15. As a result the contact will engage a contact 16 or 17 on a pinion 18 rotatable on a shaft 21 carrying the pinion 11. Engagement of the contacts 14 and 16 or 14 and 17 causes energization of a motor 7, thereby correcting the variable speed ratio 6 to its required setting by rotation of the spindle 22. The motor 7 also drives a Selsyn drive 23, 24 which effects through a pinion a follow-up movement of the pinion 18 to space the'engaged contacts apart. Thus, the spindle 22 is stopped when the necessary correction has been made. The desired value of the transmission ratio can be varied by rotation of a threaded shaft carrying the wheel 28, thereby varying the ratio of the gear 9. Expansions and contractions of the web 1 can be measured by opening a switch 32 to render the automatic control mechanism inoperative and then engaging a pinion 30 on the shaft 27 with a pinion 31 on the differential gear cage. Expansions and contractions of the web are then indicated on a scale by a pointer carried by the wheel 28: Specification 781,268 [Group XXXV] is referred to.

Title: Improved nylon filaments
Filed: 1947-12-03
Abstract: Nylon filaments having a wool-like crimp are obtained by heating while in relaxed condition an orientated nylon filament which has been treated to render it insoluble in solvents in which it is originally soluble, at a temperature 10-50 DEG  C. below the softening point of the treated filament, i.e. at least 150 DEG  C., until the filament has shrunk at least 20 per cent and preferably at least 50 per cent of its original length.  Reactants which may be used in making the nylon are mono-aminocarboxylic acids such as 6-aminocaproic and 12-aminostearic acid, dicarboxylic acids such as glutaric, adipic and sebacic acids, and diamines such as hexamethylenediamine and meta- and paraphenylenediamine.  The nylon specified is polyhexamethyleneadipamide.  The filaments may be insolubilized by heating with formaldehyde in the presence of an acidic catalyst which gives a pH below 3 in saturated aqueous solution, or by treating the filament with an aqueous solution of the catalyst, removing the solution, drying and then heating with formaldehyde, preferably in the anhydrous condition.  Other acid catalysts mentioned are oxalic acid, maleic acid, paratoluenesulphonic acid and calcium chloride.  The insoluble filaments may be heated over a heated bar, in a hot liquid or in hot air.  In an example, orientated filaments of polyhexamethyleneadipamide are soaked in a 1 per cent aqueous ammonium chloride solution, dried, treated with anhydrous formaldehyde vapour for 15 minutes at 150 DEG  C., washed, dried and heated for about 3 seconds by passing in a relaxed condition over a metal bar heated to 260 DEG  C.  The filaments are shrunk 75 per cent.  Specifications 461,236, 461,237, 514,821 and 562,555 are referred to.
