Patent GB-347428-A (GB)
IPC: D01F2/08
Filed: 1930-03-27
Abstract: Liquid to be deaerated is distributed by means of a rotating pipe 9 as a thin film over the interior conical surface in the upper part of a <PICT:0347428/III/1> vessel 11.  Deaeration is effected by creating a vacuum in the upper part of the vessel or by gentle heating of the conical surface if the liquid contains a volatile solvent.  A scraper travelling over this surface ensures regular removal of the liquid. To prevent the entry of air at the lower part of the vessel, the latter is of such a height that the hydrostatic head is sufficient for this purpose.  The vessel may be provided with a series of windows 12 to enable the liquid level to be adjusted, and with a jacket for ensuring constancy of temperature.ALSO:<PICT:0347428/IV/1> To obtain greater uniformity in composition of viscose and other spinning solutions such as are used in the manufacture of artificial threads, films, &c., a number of batches of solution as prepared in the vessels 1, are combined together in a common duct 2, are subjected as a continuous process to filtration in filters 6 and to homogenizing in a vessel 11, the solution being forwarded by mechanical means only without the employment of compressed gas. Thus, between the common duct 2 and filters 6, there may be placed a pump 3 provided with a return-flow pipe 4 so as to ensure that the filtration is carried out under constant pressure.  The streams of solution leaving the filters are reunited, and the solution then passes through a rotating pipe 9 which distributes it as a thin layer over the interior conical surface in the upper part of the vessel 11 which acts as a buffer or storage chamber, as regards the upper part as a generation chamber, and as regards the lower part 14 in which a rotating stirrer 15 is fitted as an homogenizing device.  In order to prevent the entry of air at the stuffing-box of the stirrer 15 due to the action of the vacuum that may be created in the chamber and to effect of the pump 16 supplying the solution to the spinning machine, the vessel 11 is of such a height as determined by the length of the tube 13 constituting its central portion, that the hydrostatic pressure produced in the lower part of the vessel is sufficient to prevent the entry of air.  The storage capacity of the vessel may be enlarged by providing the intermediate portion of larger diameter than the tube 13.  Deaeration is effected by creating a vacuum in the upper part of the vessel, or by gentle heating of the conical surface in the case of spinning solutions containing a volatile solvent; a scraper travelling over the conical surface ensures regular removal of the solution.  The buffer vessel 11 may be provided with a series of windows 12 to enable the liquid level to be adjusted, and with a jacket for ensuring constancy of temperature.  The pumps 3, 12 may be similarly jacketed.

Title: Improved boucle yarn
IPC: D04D1/00
Filed: 1940-06-05
Abstract: 541,694. Fancy yarns. BRY, Inc., E. & L. June 5, 1940, No. 9846. Convention date, Dec. 6, 1939. [Class 120 (iii)]. A fancy or boucle yarn is formed of two threads e.g. of mohair or wool of contrasting colours twisted about each other and each formed with loops at spaced intervals in the twist and extending inwards therefrom, the loops being "burst" or spread apart so that the fibres in the loops have a volume substantially larger than those in the unburst thread. The threads are twisted with a core thread or threads and are bound by a binder thread which may have different shrinking characteristics so as to produce a crepe effect in the twist; the core and binder thread may be of cotton, worsted, silk or rayon. As shown mohair threads 12, 13 of different colours are twisted over core threads 10, 11 and formed into loops 14, 15 which may be adjacent one another or spaced apart; the loops and the twisted area between them are bound by a binder thread 18. The yarn is washed, scoured and dried so that the mohair threads shrink relatively to the other threads and a crepe effect is produced in the twisted area while the loops spread out or become "burst".

Patent HK-112396-A (HK)
Title: Method for transmitting a video signal
Inventor: PLANTHOLT MARTIN
IPC: H04N7/00
Filed: 1996-06-27
Abstract: In the letterbox colour television system, additional data are transmitted with an appreciably reduced amplitude for reasons of compatibility, low frequency components having a relatively high amplitude. This results, however, in a reduction in the signal-to-noise ratio and disturbances in synchronization occur in known television receivers. The amplitude of the additional data can be increased without the disturbances in synchronization that occur in known television receivers if the additional data are transmitted in the form of a vestigial sideband modulation of the colour carrier. The frequency response of known IF filters can be exploited advantageously to form a Nyquist flank on the colour carrier. If the phase used is a constant V-phase of the colour carrier, any disturbances in the compatible reception are advantageously slight.
