Title: Polyethylene terephthalate copolymer container manufactured using nucleating agent
Inventor: BRONS MARCO
IPC: B65D1/34
Filed: 2009-11-06
Abstract: A container is manufactured from a material which comprises a polyethylene terephthalate (PET) copolymer and a nucleating agent, wherein the copolymer comprises at least 90 mol% polyethylene terephthalate monomer units. The container may be a foodstuff container, such as a dual ovenable tray which is stable at temperatures found in conventional ovens. Moreover, the container may be made from at least 20 weight%, and more preferably at least 80 weight%, recycled PET based on the total PET in the container. The nucleating agent can be an organic nucleating agent, preferably a carboxylic acid. The nucleating agent may be a salt, preferably a salt of an acid. In addition to PET, the copolymer contains at least one other monomer unit, wherein the other monomer unit may be derived from isophthalic acid, cyclohexane dimethanol, neopentyl glycol and diethylene glycol. In another aspect a method of manufacturing the container is disclosed.

Title: The preparation of easily soluble salts of dialkylamino-alkylamino-acridines
IPC: C07D219/12
Filed: 1935-03-30
Abstract: Salts of 9-dialkylaminoalkylaminoacridines are prepared by reacting the latter with alkylsulphonic acids or by double decomposition between a soluble salt of a dialkylaminoalkylaminoacridine and a soluble salt of an alkylsulphonic acid whereby the inorganic salt radicles are precipitated.  These salts are crystalline and very soluble in water furnishing neutral solutions suitable for injection purposes.  In examples, 2-methoxy-6-chloro-9-(a -diethylamino - d  - pentylamino) - acridine in alcohol is treated with methane- or ethane-sulphonic acid and the respective salts crystallized out on adding ethylacetate.  Samples have been furnished under Sect. 2 (5) of the dimethane sulphonates of 2-methoxy-6-chloro-9-(a -diethylamino-d -butyl)-aminoacridine and of 2-chloro-9-(a -diethylamino-b -ethyl) aminoacridine both prepared analogously to the above salts.  Reference is also made to the reaction of a dialkylaminoalkylaminoacridine with the barium salt of an alkylsulphonic acid.

Title: Colour television receiver
IPC: H04N11/16
Filed: 1972-03-03
Abstract: 1386642 Colour television GENERAL CORP 3 March 1972 [4 March 1971 11 March 1971] 10015/72 Heading H4F A demodulating circuit for a PAL colour television signal operates to reduce phase errors in the received signal by altering the phase operation of the reference oscillator 7 if the received modulation axes are rotated relative to the demodulation axes. In the embodiment shown three gates 16, 17, 18 are operated by the output of B - Y demodulator 5, gate 16 opening if the B - Y output is above a certain positive amplitude, gate 17 opening if the B - Y output has a negative amplitidue whose modulus is above a certain value, and gate 18 opening if the B-Y output is between these values. Demodulators 19, 20 and 21 are connected to gates 16, 17 and 18 and fed with R - Y reference signals from 90 degree phase shifter 23 or -(R-Y) reference signals from 90 degree phase shifter 22. If either of gates 16, 17 is open and there is no phase error in the received signal the outputs from 19 and 20 in adjacent lines are equal in amplitude and opposite in sign, and so the output of low pass filter 24 having a long time constant is zero. If a phase error is present the outputs from 19 and 20 in adjacent lines are not equal in amplitude and a correcting voltage is passed from 24 to a phase shifter 14. If gate 18 is open, but there is sufficient phase error to cause only every second line to be in the correct segment to open gate 18, the intervening lines opening gate 16 or 17, the output from 24 is passed to 14, via a switch 26 which is operated by the output of 21 via filter 25 to pass the output from 24 through an inverter 27 to produce the desired effect at 14. In an alternative embodiment (Fig. 7, not shown), gates 16, 17, 18 are dispensed with, the received signal being demodulated in four demodulators at phases 90 degrees apart and spaced 45 degrees from the B - Y and R-Y axes, the resulting outputs being matrixed before being passed to 14. In this embodiment only part of each received line may be passed to the demodulators, to eliminate non-operation of the phase correcting circuit if the sum of the B - Y components in a line is zero.

Title: Improvements in the purification of crude terephthalic acid
Inventor: BILLE HEINZ
Filed: 1959-03-24
Abstract: Crude terephthalic acid is purified by recrystallisation from a N-alkyl-pyrrolidone.
