Title: Improvements in or relating to the manufacture of artificial silk and the like
IPC: D01H13/30
Filed: 1930-02-11
Abstract: 348,644. Treating artificial filaments. BORZYKOWSKI, B., Villa Hela, Herzberg-am-Harz, Germany. Feb. 11, 1930, No. 4592. Convention date, March 1, 1929. [Classes 120 (ii) and 120 (iii).] Artificial silk and the like is mechanically cleaned and simultaneously examined during twisting from a spinning bobbin or during winding or reeling from a cake by being guided through a cleaning or clearing device and then through a dressing, finishing or softening device. The invention is a development of the method described in Specification 311,391, [Class 120 (ii), Spinning, twisting, &c.], wherein artificial silk or the like is treated in the bobbin or cake form so that it may be brought directly into the wound form for textile manufacture without rewinding, but the treatment may also be applied during intermediate winding or reeling. The filament a passes from the spinning bobbin b through a tensioning arrangement c, a cleaning device d preferably of a hairy material, then through a shaving device or eyelet e and over a roller f which rotates in a dressing, finishing or softening agent. Filaments of poor quality will tear frequently at the cleaning and shaving devices, and a mechanical examination will thus be effected.

[Class 110 (iii).] The inlet edge of a blade a near the tip is machined as at b so that a flat or bevel-shaped edge is formed which resists erosion of water particles in the steam which impinge on the surface b approximately in the direction of the dotted lines. The surface b may be parallel to the blade axis inclined, or the plane of b may vary along the blade and join the normal inlet edge in a curved fillet. Where sheathing is fitted to the inlet edge of the blade, the flat b is machined thereon. The flats may be slightly curved or knurled. Specifications 3004/15, [Class 83 (iv), Metals, Working], 309,235, [Class 110 (iii), Turbines &c.], and 347,138 are referred to.

Title: Improvements in or relating to siliceous dispersons
Inventor: HILL DEREK ALFRED WHEELER
IPC: D06M15/643
Filed: 1948-02-19
Abstract: Siliceous dispersions are obtained from organic silicates either by emulsifying the silicate with water and adding a non-metallic soap or by dissolving the said soap in the silicate and emulsifying the product with water.  Mono-, di-, or tri-ethanolamine soaps can be used singly or in admixture, and ethyl orthosilicate or a partially hydrolysed ethyl silicate are the preferred silicates.  Sodium metaphosphate is added as a water softener before the addition of the silicate.  The dispersions are applied to textile fibres to increase their surface roughness.

[Also in Group XXV] A machine for laying up cable cores to form a composite cable, particularly a quadding- machine for laying up cores into a cable having balanced quads, comprises a carriage A and bobbins E mounted thereon, from which the cores are drawn off to be laid as required, together with a cage device F through which the cores pass to a lay-plate H, the cage device, being in two parts capable, when released, of relative angular adjustment, one of the parts having locations to receive the cores and being rotatably held by the machine frame so that the relative positions of pairs of the cores can be reversed. In the machine shown, the cage device F, which forms the upper bearing of the spindle B of the carriage, comprises inner and outer elements 1 and 2, Fig. 2, normally locked to rotate as a unit by bolts 3. The inner element comprises a spider with four arms 4 having cylindrical ends 6 so as to be capable of riding in circumferential grooves in the annulus constituting the outer element 2 of the cage device, which in turn is rotatably held in a ring fixed to the machine frame. The spiders are inserted through slots 8 extending from the under face into the grooves. The arms 4 provide four locations for the respective cores. To interchange the positions of the pairs of cores in the cable, the outer annulus 2 is freed and the cores X<SP>1</SP> moved into radial recesses 9 and the annulus turned with the two cores through 180 degrees to the new position. To accommodate the change of path of the cores from the bobbins, the interchanged cores are passed over guide pulleys 10 and jockey pulleys 11 adjustably located so as to ensure that the cores enter the apertures in the cage device at their original angle. The arms carrying the jockey pulleys 11 are preferably universally mounted in relation to the spindle B. The lay plate H is provided with two diametrically-opposite slots 27<SP>1</SP>, Fig. 6, giving access to two of the die-receiving apertures 28. These apertures are fitted with interchangeable dies 29 provided with flanges 30 with edge flats 31 to enable them to be unscrewed from the lay plate. The dies with their cores can then be interchanged and the angular position varied by 180 degrees.

Abstract: 1468231 Data storage systems HEWLETTPACKARD CO 7 Feb 1974 [14 May 1973] 5624/74 Heading G4C A multiport memory module, Figs. 4a-4f (not shown), comprising a memory (146, 147, Fig. 4b, not shown) which requires periodic refreshing includes means (149, Fig. 4e) for counting the number of times a refresh operation has occurred, irrespective of through which port the refresh clock pulse sequence has been gated. Each port comprises a plurality of conductors for data, clock and control signals, and connects a respective controller, Figs. 3a-3c (not shown), to the module. Various data processing means can be selectively gated to the memory via the controllers. The refreshing clock pulse sequence (CLK(1), Fig. 4f, CLK(2), Fig. 4e) may be applied to the memory either via that port through which one of the processing means is now or was last gated to the memory at the time of a required refresh operation, or, if no processing means is currently gated, the sequence may be applied via a predetermined one of the ports. The operating interval during which a processing means is gated to the memory is shorter than the periodicity of the refresh operation, and means is provided to detect the presence of a priority request for access by a processing means. If such a request occurs at the time of a refresh operation, access occurs in the operating interval immediately after the current refresh operation, the refresh clock pulse sequence being again applied during the next interval.
