Patent GB-576658-A (GB)
Title: Improvements relating to the manufacture of micro porous material
IPC: H01M2/16
Filed: 1943-09-06
Abstract: Microporous material is produced by producing a dough by incorporating in polystyrene fine particles of a material which can be subsequently removed therefrom and a solvent for the polystyrene which acts as a temporary plasticizer thereof, the resulting dough being then formed into desired shapes, the solvent removed and the solid dough treated for the removal of the particles so as to leave micropores in the solid polystyrene. Specified materials, the fine particles of which may be added, are starch and dextrin, while xylene and methyl cyclohexanone are specified as solvents.  The dough may be shaped by moulding, extrusion or rolling and the solvent removed by evaporation.  The starch or dextrin is swollen by treatment with hot water and then removed by treatment with hot sulphuric acid or with an enzyme, e.g. malt diastase at 60 DEG  C., or with hot water for some time. The shaped dough is then washed in water and dried, and it may be treated with a wetting-out agent such as highly sulphonated oil before the drying.  Wood flour or the lignin bodies obtained from waste sulphite liquors in paper-making plants, chlorinated diphenyl or polyisobutylene or carbon black may be added to the polystyrene. The final products may be used as diaphragms or separators for electrical accumulators.

Title: Improvements in or relating to mechanism for and method of producing, automatically,multiple yarn hosiery upon a circular, independent needle, knitting machine
IPC: D04B9/06
Filed: 1947-06-02
Abstract: 647,720. Knitting. HEMPHILL CO. June 2, 1947, No. 14590. Convention date, July 27, 1946. [Class 74 (ii)] In the manufacture of a stocking on a cylinder and dial machine, the leg is formed by knitting simultaneously four yarns 5 ... 8 fed separately to the needles, three of the yarns being knitted by the dial needles only and the fourth yarn being knitted by the cylinder and dial needles. The loops of the yarn knitted by the cylinder needles extend over the three courses of the other yarns on the face of the fabric so that by selection of any one of the four yarns patterning can be readily effected. Immediately prior to the commencement of the heel the loops on the dial needles are transferred to the cylinder needles and a normal heel, by widening and narrowing during reciprocation of the cylinder, is formed. The foot portion of the stocking is formed in the same way as the leg but it may be knitted so that one particular yarn only is brought to the face of the fabric in the sole portion. Alternatively the sole may be knitted by knitting the four yarns in succession on the dial needles only. A ring toe is then formed after the loops on the dial needles have been transferred to the cylinder needles and additional intermediate needles spaced alternately with those already used in the cylinder are brought into operation. The toe of the stocking is formed by reciprocation in the normal manner. Needle jacks are provided for the selection of the needles to effect the loop transference and to raise the intermediate needles at the commencement of the ring toe. Specifications 370,023 and 479,324 are referred to.

Patent GB-677247-A (GB)
Title: Improvements in or relating to direct current electric supply systems
IPC: H02P7/34
Filed: 1949-06-01
Abstract: 677,247. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and SCOTT, P. June 1, 1950. [June 1, 1949] No. 14714/49. Class 38 (iii). [Also in Group XXXV] A D.C. supply system, which may be arranged to feed a D.C. motor so as to form a Ward-Leonard control system, comprises a main generator having a field winding fed from an exciter generator, wherein the excitation of the latter or of a pilot exciter generator is arranged to be depended upon a reference electrical quantity and upon the main generator P.D., the excitation current of the field of the exciter generator or pilot excitor generator being derived through a non-linear resistance tending to reduce the main generator excitation when the main generator P.D. or output current is relatively large. The Figure shows a Ward-Leonard motor control system in which a generator armature 10 is connected to the motor armature 13. The field 12 of the generator is fed from the armature 16 of the main exciter the field winding 17 of which is in turn fed from the armature 18 of an auxiliary exciter. The latter has three field windings 20, 21, 22. The winding 20, which is fed from the supply through a potentiometer 24, carries a steady reference current, the second winding 21 carries a current proportional to the output voltage of the main generator and is in opposition to the first winding 20, and the third winding 22 assists the second winding 21. The circuit of the winding 22 includes a metal rectifier 30 which, on account of its non-linear characteristic and of the position of its non-linear characteristic and of the position of the slider 27 on a resistance 26 acting as a control means, has a voltage across it so arranged in its voltage/current characteristic curve as to be at the critical value where the slope of curve changes rapidly when the current supplied by the main generator is at the required current limit. Thus the current in the field winding 22 is arranged to be responsive to the output current of the main generator by adjusting the position of the slider 27 or to the output voltage by supplying this winding 22 through a non-linear resistance from a potentiometer connected across the generator output. Instead of making the field winding 22 responsive to the main generator output current, it may be made responsive to the main generator voltage output by feeding it from a tachometer generator through a non-linear resistance from a potentiometer across the main generator. In order to limit the current on regeneration as well as on motoring a second rectifier 31 may be connected in parallel to and in reverse to the first rectifier 30. Instead of exciting a field winding of a pilot exciter generator to limit the main generator current, a similar effect is obtained by exciting a further field winding of the main excitation generator in the same manner. If desired, further field winding(s) may be provided to the pilot exciter to improve stability.
