Title: Process and apparatus for melting linear high polymers of organic substances
Inventor: FRIEDRICH DIPL-ING DR ALFRED
IPC: D01D1/04
Filed: 1949-09-20
Abstract: In melting linear high polymers of organic substances in the production of endless filaments, strips and the like, in particular, high polymers of the polyamide, polyethylene, polyvinyl and polystyrene groups, and the groups <PICT:0682184/IV (a)/1> <PICT:0682184/IV (a)/2> of derivatives of polyacrylic acid, the polymers in granular or like form are supplied intermittently in small charges of substantially equal quantity to a melting chamber, and the melt is immediately removed therefrom and passed to a collecting chamber from which it is led continuously, the charging of the melting chamber being regulated by a control member, in accordance with the level of melted material in the collecting chamber.  Apparatus for carrying out the process comprises a heated melting chamber 11 into which a measured quantity of the substance to be melted is periodically introduced by means of a reciprocating piston 12 having a filling recess 13 for containing the measured quantity which is discharged from the recess by rotating the piston through 180 degrees, a discharge aperture being provided at the lowest point of the melting chamber and communicating with a collecting chamber from which the melted material is led to spinning or casting devices, movement of the piston, and therefore the rate of feed, being regulated by a control member (not shown) in the collecting chamber in accordance with the level of melted material therein.  As shown in Fig. 1, the filling recess 13 is replenished from a container 16 after each withdrawal of the piston from the melting chamber.  The piston reciprocates in a cylinder 14, which may be water jacketed and also heat insulated from the melting chamber 11 by a ring 18.  Liquefied material from the melting chamber 11 flows through an aperture 19 at its lower end to a receiver 20 and is discharged continuously therefrom through a pipe 21 leading to the spinning or casting devices.  The melting chamber 11 may be heated by steam coils cast in the wall (as shown in Fig. 1), or by electrically heating coils of high resistance wire on the outside of the chamber, or by induction or eddy current heating of the chamber wall, or by high-frequency heating of the material itself, or by supplying heat to the material by infra-red radiation.  In the form shown in Fig. 7 the material to be melted is received in a container 24 of insulating material such as glass, stone or porcelain which is provided at its lower end with one or more openings 26 of such a size as to prevent the passage of solid particles of material whilst allowing the passage of melted material to the collecting chamber.  Heating is effected by a high-frequency electrical field alternating between electrodes 27 disposed one on each side of the container 24.  The melted material is discharged from the collecting chamber through an aperture 32.  The walls of the container may be cooled between charging cycles by a blast of air or gas.  Specification 533,307 is referred to.

Title: Improvements relating to Television Dropout Compensators.
Inventor: HODGE FREDERICK JERI
IPC: H04N9/882
Filed: 1967-05-24
Abstract: 1,167,074. Colour television. MINNESOTA MINING & MFG. CO. 24 May, 1967 [25 May, 1966], No. 24235/67. Heading H4F. Drop out of television signals played back from a magnetic tape may be compensated by a delay line and switch system whereby signals due to the preceding line may be substituted during the period of drop out. When the signals are colour signals of the N.T.S.C. type this results in colour falsification since the colour subcarrier signals for corresponding points in successive lines differ by 180 degrees, as illustrated in Fig. 3, due to the odd half multiple relation between the subcarrier and line frequencies. In accordance with the invention the difficulty is overcome by the provision of delay means which subjects both the luminance and chrominance signal to a delay of one line period and further means which inverts the phase of the chrominance signal. In a first arrangement, Fig. 5, separate delay lines 50 and 58 are provided in luminance and chrominance channels, the chrominance channel including also a phase inverter 60. Delay line 50 is a lumped constant line which also functions as a low-pass filter to select the luminance signal. Line 58 is a glass delay line. A second arrangement, Fig. 6 (not shown), uses glass delay lines in both channels with amplitude modulation and demodulation stages preceding and following the line in the luminance channel so that the signal is translated through the line on a suitable carrier frequency. A third arrangement, Fig. 7 (not shown), uses a glass line in a common channel followed by filters to separate the luminance and chrominance signals and direct the chrominance signal to a phase inverter. Short adjustable delays are provided for each of the separate signals. Reference is made (without giving details) to a common delay channel including a phase inverter arranged to operate over only a selected range of frequencies.

Title: The manufacture of new anthraquinone dyestuffs
IPC: C09B1/42
Filed: 1932-09-01
Abstract: An aminoanthraquinone or a derivative thereof is acylated with the acid or acid halide of a dinitrodiaryldisulphide-dicarboxylic acid wherein the nitro groups are in o-position to the -S-S- linkage in presence of an agent facilitating acylation and reducing the disulphide obtained to the corresponding o-aminomercaptan and treating this with a halogen acetic acid to give an o-aminothioglycollic acid.  The dyes are applied as in Specification 377,740.  Suitable aminoanthraquinones are those mentioned in Specification 2702/09, [Class 2 (iii)], and suitable acylating agents are 2.2<1>-dinitro-4.4<1>-dicarboxydiphenyldisulphide, 2 . 2<1> - dinitro - 5 . 5<1> - dicarboxydiphenyldisulphide, 2.2<1>-dinitro-5.5<1>-diethoxy-4.4<1> -dicarboxydiphenyldisulphide, and 2.2<1>-dinitro-6.6<1>-dicarboxydiphenyldisulphide.  In examples: (1) 2.2<1>-dinitro-4.4<1>-dicarboxydiphenyldisulphide is converted to the carboxylic acid chloride, the product condensed with a  - aminoanthraquinone, reduced with hydrosulphite and condensed with sodium thioglycollate, finally being oxidized by means of peroxide; wool is dyed orange-yellow shades which change to fast yellow on lactamisation; the a -aminoantraquinone may be replaced by 1 - amino - 4 - methoxyanthraquinone (orange-scarlet shades on lactamisation), 1-amino-4-hydroxyanthraquinone (similar shades), 1-amino-5-methoxyanthraquinone (yellow shades on lactamisation), 1-amino-5-chloroanthraquinone (yellow shades on lactamisation) and 1-amino-4-methylaminoanthraquinone (reddish-blue shades on lactamisation); (2) similarly to (1) 2.2<1>-dinitro-6.6<1>-dicarboxydiphenyldisulphide may be condensed with a -aminoanthraquinone, reduced and converted to a dye which yields similar shades on lactamisation; using 1-amino-4-methoxyanthraquinone instead, bright scarlet shades are obtained on lactamisation.  The dinitrodiaryldisulphidedicarboxylic acids may be obtained by reacting an appropriate halogennitrobenzoic acid with an alkali sulphide, polysulphide, thiocyanate or xanthate and if necessary oxidizing, or hydrolysing and oxidizing the products; or an appropriate diazotized nitroaminobenzoic acid is treated with an alkali disulphide, and if necessary the product hydrolysed and oxidized.
