Title: Improvements in the manufacture and production of anthraquinone derivatives
IPC: C09B1/515
Filed: 1933-12-18
Abstract: p-Diaminochrysazine is alkylated under such conditions as regards the period of reaction, the concentration of reagents and the temperature that the amino groups are only partially alkylated, the end of the reaction being ascertainable by the fact that a solution of a sample withdrawn, worked up and dissolved in a mixture of benzoylchloride and benzene (1 : 5) gives a spectrum in which two of the characteristic absorption bands of the initial material have almost or just entirely disappeared.  The products are especially suitable for dyeing cellulose esters and ethers in fast shades not changed in artificial light.  Suitable alkylating agents are dialkyl esters of sulphuric acid, arylsulphonic acid esters, oxyalkylhalides and alkylene oxides.  In examples p-diaminochrysazin is alkylated with monomethylsulphate, dimethyl- and diethyl-sulphate, toluene sulphonic acid methyl and butyl esters, ethylenechlorhydrin and ethyleneoxide, and a mixture of methanol and concentrated sulphuric acid.  German Specification 125,576 is referred to.

Title: Injection moulding machine and method
IPC: B29C49/00
Filed: 1976-09-02
Abstract: The injection moulding machine comprises a rotating screw (2) which is moved axially by means of a hydraulic piston (6) and thereby forces the plasticated polymer into the injection mould (9). In the mould (9) a pressure measuring element (14) is arranged close to the sprue, which pressure measuring element (14) controls the hydraulic pressure to the piston (6) by means of a controller (13) and a servo valve (11). During solidification of the melt in the mould (9), this hydraulic pressure increases because of the viscosity increase and the contraction of the plastic. This pressure rise is registered by a second pressure measuring element (line 12), by means of which the start of the solidification phase can be precisely ascertained. The holding pressure time will automatically end an adjustable period of time after this pressure rise. The cycle time can thus be optimised. <IMAGE>

Title: Process and apparatus for drawing synthetic linear polyester yarns
Inventor: RISELEY ERIC IVAN
IPC: D02J1/22
Filed: 1959-10-28
Abstract: Synthetic polyester multi-filament undrawn yarn with an optical birefringence not varying more than \sB0,0003 from a value lying between 0,002 and 0,015 is rapidly hot drawn three to six times its undrawn length between feed and draw rolls, heated between the feed and draw <PICT:0903027/IV(a)/1> <PICT:0903027/IV(a)/2> rolls by sliding contact to deflect it 50-270 degrees, preferably 90-180 degrees of arc, in a first zone comprising a stationary heated curved convex metal surface maintained at a temperature between 10 DEG C. below and 25 DEG C. above the second order transition temperature of the polyester, under a tension so that stretching is limited to less than 20% and so that no drawing occurs, passing the heated yarn without substantial cooling to a second zone comprising a small diameter non-rotatable snubbing pin, near to the first zone, causing the tension in the second zone to effect substantially all the drawing of the yarn, maintaining the second zone at the second order transition temperature or at a temperature between this and a temperature 45 DEG C. above the S.O.T.T. followed, if desired, by heating the yarn in a third zone maintained at a temperature 60 DEG -130 DEG C. above the S.O.T.T. but at least 30 DEG C. below the melting point of the polyester.  The curved convex surface should be at least 1 1/2 inches but not more than 6 inches in radius, and may be provided with flat portions at ether or both ends.  The snubbing pin should preferably be 1 to 2 inches from the first zone and have a diameter of 3/4 inch.  Draw speeds up to 1,000 yards/minute may be used.  As shown in Fig. 1, undrawn yarn from positive feed rolls is passed to a stationary convex surface (1) consisting of a heated segment of a metal cylinder for deflecting the yarn 90 degrees of arc.  The segment has a sand-blasted chromed surface to reduce friction between it and the yarn.  From the segment the yarn is passed to a snubbing pin 2 which may be positioned at A or B.  The yarn is looped around the pin a number of turns which depend on the denier of the yarn and is then passed to the draw roll having a diameter 3 to 6 times that of the feed roll and mounted on the same shaft. The yarn is looped round the draw roll and a separating idler roll and then passed downwards where it is wound as to a rotating draw-twist bobbin (not shown).  A further heating means in the form of a hot plate 3 may be provided between the snubbing pin 2 p  and the draw roll.  Alternatively the hot plate may be positioned beyond the draw rolls, as shown at 19 in Fig. 2, but in that case, the yarn is passed over slower rotating relaxing rolls 17 and 18 before winding up.  The invention enables higher drawing speeds to be used without detriment to the yarn and provides yarns having more uniform dye uptake and more uniform shrinkage in boiling water.  Examples are furnished of the drawing of polyethylene terephthalate yarns.  U.S.A. Specifications 2,533,013 and 2,556,295 are referred to.

When the first of the trackways 17 has received three stacks 11 from the device 10 a sensor arm (34), Fig. 5 (not shown), detects the presence of three such stacks 11 and operates a ram 44 to temporarily retract the latch 46 so that movement of the pallet 16 under gravity on the rollers 29 occurs, the latch 46 stopping movement of the pallet when the next set of trackways 17 is engaged thereby, that set of trackways being then aligned with the device 10, and when filled, the next set of trackways 17 receives three stacks 11. The trackways 17 are provided with openings (27), Fig. 3 (not shown), which receive the rollers 13 when the fully loaded pallet 16 is subsequently lifted for transportation so that the stacks 11 are securely mounted on the pallet 16, but during the passage of the stacks 11 on to the pallet 16 the rollers 13 are prevented from entering the openings (27) because the latter are filled by enlargements 31 formed on the two rollers 29 which are located beneath the trackway 17 which is receiving stacks 11, as shown in Fig. 4. The fully loaded pallet 16 is transferred by a fork lift truck to a distribution station (53) at which there is an inclined support which permits the stacks 11 to roll by gravity along tracks (56) to feeder devices (54), Fig. 9 (not shown), the tracks (56) being provided with track-switching apparatus, Fig. 10 (not shown), which permit a particular track (56) and feeder device (54) to be selected.
