Title: Method of producing dyed material
IPC: D06P1/00
Filed: 1971-01-29
Abstract: 1386072 Dyeing J & P COATS Ltd 4 Feb 1972 [29 Jan 1971 3 April 1971] 3536/71 and 8623/71 Heading D1B A process of producing a dyed material consists in applying to material capable of being dyed a dyeing medium containing a dye and a non-aqueous solvent for the dye and causing the solvent to reject positively the dye and thus increase the relative affinity of the dye for the material capable of being dyed by adding to the dyeing medium a material for which the solvent has a higher affinity than it has for the dye. The components of the solvent dyeing medium may be all mixed together before the application to the material to be dyed or the dye may be added after the other components have been mixed. Atlernatively a first component incorporates a dye contained in a solvent and a second component comprises the material for which the solvent has a higher affinity than it has for the dye which components may be applied consecutively to the substrate. The material may be washed after dyeing.

Patent GB-397025-A (GB)
Title: Improvements in or relating to processes of making reaction products of ketene
IPC: C07C45/88
Filed: 1933-02-07
Abstract: Reaction products of ketene are formed by thermally decomposing an organic substance such as acetone which yields ketene, rapidly passing the reaction products into intimate contact with a liquid cooling-medium nonreactive with ketene to condense less volatile bodies, and then utilizing the uncondensed gas to form reaction products of ketene.  The gases containing ketene are passed directly from their source by a pipe 10 into a scrubber 11 containing packing upon a perforated plate 13.  Suitable <PICT:0397025/IV/1> cooling-liquids are hydrocarbons such as pentane, hexane or benzene, aliphatic ethers such as ethyl or isopropyl ethers, and aliphatic ketones such as acetone and methyl ethyl ketone.  When the ketene is produced from acetone, the scrubbing liquid may be acetone at 40-50 DEG  C.  The gases leaving the scrubber by a pipe 16, which contain a higher proportion of ketene, are led to a second scrubber 17 and contact with a liquid supplied from a pipe 19. This liquid may be non-reactive, in which case a solution of ketene is produced and is used in reactions as desired, or it may be reactive, such as water, acetic acid, propionic or butyric or other aliphatic acid, an alcohol, aniline or substances containing a hydroxy or carboxylic group.  In an example, acetone is cracked at 600-750 DEG  C. to produce ketene, the gases being immediately washed with a large volume of acetone, the time between the exit of the gases from the cracking furnace and their entry to the scrubber being less than 0,03 seconds.  To obtain a solution of ketene, which may be used as an acetylating agent, the absorption should be effected below 30 DEG  C. and preferably below 0 DEG  C., preferably under pressure.  The solution may be kept for a considerable time if cooled with solid carbon dioxide or otherwise kept at very low temperature.  When utilizing the ketene solution, pressure should be employed to maintain it in solution at the reaction temperature.

Title: Improvements in or relating to signalling systems for television
IPC: H04N9/68
Filed: 1956-02-07
Abstract: 799,100. Automatic volume control. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 7, 1956 [Feb. 10, 1955], No. 3798/56. Drawings to Specification. Class 40 (4). [Also in Groups XL (b) and XL (c)] Relates to a multiplex television transmission system, such as a colour system, utilizing a main image signal together with two or more auxiliary carriers located either inside or outside the band of the main signal and modulated with further image signals in such manner as not to require the transmission of reference signals to effect demodulation at a receiver. In accordance with the invention, gain control signals for the auxiliary carriers to compensate for frequency selective fading or attenuation in a radio or cable channel are added to the transmission during the back porches of the line synchronizing intervals in the form of short bursts of oscillations of frequencies at least approximately equal to the respective frequencies of the auxiliary carriers. The amplitudes of these bursts are held constant. At a receiver, Fig. 9 (not shown), which is described for a system employing two auxiliary carriers, the overall gain of the radio-frequency and intermediate-frequency stages is first controlled in a conventional manner in response to the amplitude of the line synchronizing pulses, which are gated from the output of the detector, and then the amplitudes of the auxiliary carrier signals alone are controlled in response to the amplitudes of the corresponding bursts. Following the detector, the video channel feeds a pair of band-pass filters, detectors and amplifier channels, by means of which the auxiliary carriers are separated and the further image signals derived. These signals each include after detection' a pulse corresponding to the associated burst signal. The pulses are gated out by suitably delayed horizontal fly-back pulses and applied through smoothing networks to control the gain of the amplifiers in the respective channels. As described, the receiver includes also a sound channel responsive to a signal located just outside the upper edge of the image channel, and it is stated that the gain of the sound channel may also be controlled by the burst whose frequency is located closest to that of the sound carrier. The Specification describes two transmitter arrangements for adding the gain-control bursts to the transmitted signal. In one, Fig. 3 (not shown), a pulse is added to each of the further image signals during the back-porch interval so that, when these signals modulate the auxiliary carriers, bursts at the auxiliary carrier frequencies are produced in response to the pulses. In. the other, Fig. 8 (not shown), the bursts are produced separately, by modulating the auxiliary carriers by suitable pulses, and added to the combined main and further image signals before transmission.
