Abstract: 1462314 Twist tubes for false twisting HEBERLEIN & CO AG and ATELIERS ROANNAIS DE CONSTRUCTIONS TEXTILES 28 Feb 1975 [5 April 1974] 8419/75 Heading D1D A twist tube having a bore 5 extending from end to end of the tube, Fig. 2, and through which yarn passes when the twist tube is in operation, has a single pin 6 extending across the bore, the pin 6 being mounted with its axis c displaced laterally with respect to the axis a of the bore 5 by a distance which is a fraction of the maximum diameter of the pin. As shown the pin 6 may be formed with a cylindrical concave surface intermediate its ends, and the gap between the axis a and the minimal circumference of the pin may be of the order of half the yarn thickness.  To aid threading the yarn around the pin there is a transverse bore 7', 7", the bore 7" being larger than the bore 7' to compensate for the unbalance created by the pin 6 being displaced to one side. Alternatively the bores 7', 7" may be equal and a lateral recess may be formed elsewhere on the side towards which the pin is laterally displaced. The axis of the bore 7', 7" may be tangential to the minimal circumference of the pin 6.

Inventor: CAT ARTHUR HENRI DE
IPC: G03C7/36
Filed: 1957-03-15
Abstract: 2-Nitrophenyl-4-keto-3, 1, 4-benzoxazines are prepared by condensing the sodium salt of anthranilic acid with o-, m,- or pnitrobenzoylchloride and treating the resulting amide with acetic anhydride, thus causing the loss of a molecule of water. By treating these benzoxazines with pyridine and concentrated ammonium hydroxide, nitrobenzoyl - anthranilamides are formed, which by boiling in dilute sodium hydroxide are converted into 2-nitrophenyl-4-quinazolones. Reduction with hydrogen and a nickel catalyst gives the corresponding 2-aminophenyl-4-quinazolones.  The latter may be refluxed in dimethyl-formanide with an ester XCH2CO2Et (X is carboxylic acyl) to yield 2-(acyl-acetaminophenyl)-4-quinazolones. Reference is made to the preparation of such compounds wherein the acyl group X is benzoyl, a -furoyl, a -thienoyl, p-anisoyl or acetyl.

A transverse beam 2 carries adjustably the tracer head 4 with interchangeable tracer 8 and milling head 3, the cutter 6 being driven by a motor 7. The pattern 9 is secured to a table 10 mounted on compound slides 11 controlled by hand wheels 13, 14. These slides are carried on a bracket 12 adjusted periodically by a hand wheel 15. The table movements may also be effected automatically. The work 18 is mounted on a trailer table 16 supported freely on a second table 17 mounted similarly to the pattern table on compound slides 27 and vertically adjustable bracket 26 controlled by hand wheels 28 ... 30. The tables are rigidly connected for copying with stationary tracer and cutter axes by means of slotted angle brackets 20, 21, the slots of which are arranged to provide adjustments in three directions. In a modification, the connection between the pattern and trailer tables is freely movable vertically through coacting grooves 37, 38 and plate 39 as shown in Fig. 4. In this form, the relative horizontal adjustment of work and pattern in the plane containing the tracer and cutter axis is effected by relative adjustment of heads 3 and 4 on the beam 2. Instead of using the trailer table 16, the table 17 may be driven from the table 10 or vice versa by connection of the respective table actuating means, the connection being such that it may be made and broken in different relative positions of the tables. Also several work tables may be controlled simultaneously by a single pattern table. In some cases, for heavy work, the trailer table or tables may be supported on roller bearings.

Filed: 1942-06-30
Abstract: 562,952. Magnetos. TRIGGS, W. W. (Seymour Corporation of Delaware). June 30, 1942, No. 9021. [Class 35] The rotor comprises a cylindrical magnet 19, Fig. 4, clamped between end plates 14, 15, carrying laminated and toothed polepieces 20 which co-operate with similarly toothed stator poles 23, forming two axially spaced series of circularly disposed tooth formations which come into alignment simultaneously during the movement of the rotor. Spaced round the remainder of the stator casing are a number of bars 50, Fig. 2, which short circuit the rotor teeth 22 when the rotor and stator are in the minimum flux position, and are of sufficient crosssection to take the whole magnet flux without saturation. This prevents demagnetization of the rotor magnet in operation or during coil replacement. The coil, distributer and interrupter are generally similar to Fig. 8 of Specification 562,951. In manufacture, it is desirable to avoid open circuiting the rotor after it has been magnetized and during its transfer to the stator. A number of keepers are therefore inserted in the notches 21, and spanning the two poles 20, and these are not removed until the magneto is assembled. Specification 550,894, [Group XXXVII], also is referred to.
