Title: Nozzle assembly for use in hydraulic jet looms
IPC: D03D47/30
Filed: 1976-07-02
Abstract: The nozzle is designed as a device for straightening the liquid medium. At the same time, a pressure chamber (8) is filled in such a way that the liquid medium is fed through an orifice (2) of a cylindrical hollow body (1) into a circumferential groove (4) of an insert (3), from which it passes through at least four overflow orifices (5) into the pressure chamber (8). This is filled uniformly, without an undesirable turbulence of the liquid medium occurring. The pressure medium flows out of the pressure chamber (8) in an interrupted manner through the inner circular ring of a shut-off cone (9) mounted movably in the insert (3) and flows around an inserted weft thread which passes through the middle of the conical nozzle orifice (7). <IMAGE>

Title: Means for measuring rate of change of frequency

Filed: 1959-08-14
Abstract: 871,773. Frequency detectors; radio navigation. COLLINS RADIO CO. Aug. 14, 1959 [Jan. 2, 1959], No. 27877/59. Classes 40(5) and 40(7) [Also in Group XXXVI] Apparatus for measuring the rate of change of frequency of a signal comprises a first and a second mixer, means for delaying the signal and for supplying the delayed signal to the first and second mixers, means for supplying the signal directly to the first mixer, and a phase shifter for changing the phase of the signal and applying the result of the second mixer; the outputs of such mixers being combined in means producing a rotating magnetic field associated with further means for measuring the angular velocity of rotation of such rotating field. A variable frequency signal derived, e.g. by reflection or transmission by a moving object with a rate of frequency change determined by the radial acceleration of such object excites receiver 11 (Fig. 1) energizing mixer 16 both directly and through time delay network 13 and also energizing mixer 17 both through the time delay network and through a quadrature network 12. The mixer outputs in quadrature represent in frequency the rate of frequency change of the input signal and energize an electro mechanical device 36 producing a rotational velocity determined by the angular velocity of a rotating field produced by the outputs. The device may comprise (Fig. 3) a 400 c.p.s. chopper 42 producing at the outputs of filters 47, 48 signals at 400 c.p.s. modulated by the quadrature outputs of the mixers (Fig. 4 not shown) which energize the stator windings of a biphase resolver 53 to produce a rotating magnetic field. The voltage induced in the rotor winding operates biphase servomotor 56 through servo amplifier 54 to drive the rotor at a speed proportional to the input signal rate of frequency change at which the amplifier input is a null and the rotor follows the field rotation. A biphase tachometer generator 60 has one winding energized from the 400 c.p.s. source so that the other develops an alternating signal, representing in amplitude the rate of change of input signal frequency, fed back to the rotor circuit of resolver 53 to prevent hunting and rectified by 400 c.p.s. chopper 66 and capacitance 68 to develop a unidirectional voltage representing rate of input frequency change, measurable by a meter (not shown). The quadrature network may be connected in the delay network input (Fig. 5, not shown).

Store 2 is a counter-register, and stores 8, 8a are re-articulating registers. A unit 26 provides a delay equal to that of part 18a so that the recirculation times of the two loops of 8 and 2, 16a, 18a are the same.

Abstract: 279,489. I. G. Farbenindustrie Akt.- Ges. Oct. 23, 1926, [Convention date]. Samples furnished. Thioindigoid dyes are obtained by treating with a ring closing condensing agent a 3- methylbenzene 1-thioglycollic acid substituted in the 2-position by -CN, -CONH2, or -COOH, and either oxidizing the 4-methyloxythionaphthene or condensing it with a diketone or a reactive derivative thereof. According to examples (1) 3-methylbenzene-1-thioglycollic-2-carboxylic acid nitrile is heated with caustic soda solution and the resulting 3 - amino-1-thionaphthene-2-carboxylic acid converted into the oxythionaphthene by heating with dilute sulphuric acid and oxidized to the dyestuff in the usual manner; (2) 3-methylbenzene-1-thioglycollic-2-carboxylic acid is melted with caustic soda and a little water at 180-200‹ C. and the product oxidized in the usual manner. The 4 : 4<1>-dimethylthioindigo so obtained dyes cotton from the vat in red shades which are faster to light than those given by the further substituted dyestuff. 3-Methylbenzcne - 1 - thioglycollic-2-carboxylic acid nitrite is obtained from 1-methyl-2-amino- 3-nitrobenzene by substituting the cyano group for the amino group, reducing the nitro group to amino and exchanging the latter for the thioglycollic acid residue by way of the diazo compound. 3-Melthylbenzene - 1 - thioglycollic - 2-carboxylic acid is obtained from 1-methyl-2-amino-3-chlorbenzene by replacing the amino group by cyano, saponifying the latter, and exchanging the chlorine for the thioglycollic acid residue by converting to the thiophenol and condensing with chloracetic acid.
