Title: Metachrome dyeing procedure
IPC: D06P3/20
Filed: 1947-03-24
Abstract: Nitrogenous textile fibres are dyed by means of a chromable dyestuff in the presence of a chromium salt and a cationic surface-active agent, the initial pH of the bath being sufficiently high to prevent rapid chromation but insufficiently high to damage the fibre, and dyeing is continued at an elevated temperature whilst the pH is gradually lowered to promote rapid dyeing and chromation.  Magnesium sulphate may also be present in the bath.  The initial pH is preferably not greater than 9.  In an example: (1) wool is immersed in a bath containing a chrome dye and a mordant obtained by mixing potassium dichromate with a condensation product of octadecyl guanidine bicarbonate and ethylene oxide deposited on magnesium sulphate, the initial pH of 8.5 to 9.0 being lowered during dyeing by adding acetic acid.  In other examples: (2) yellow corn dextrine is added to the mordant which is used as in (1); (4) the mordant contains also dextrine; (5), (7) and (9) yellow corn dextrine, the condensation product of (1), potassium dichromate and magnesium sulphate are colloidized in a mixer and the dyeing carried out while adding sulphuric acid to lower the pH; (10) the condensation product of polyethylene oxide and the dimerized acid obtained by heating soya bean acids is used as surface-active agent in the process of (1); (15) yellow dextrine and the condensation product of (1) are blended with a chrome dye and added to a dyebath containing also ammonium acetate, magnesium sulphate and potassium dichromate, the dyeing being started at pH 6.0 and reduced during dyeing to 5.0 by adding acetic acid; (16) wool is dyed from a bath containing a blend of the condensation product of (15) with a chrome dye, ammonium sulphate and potassium dichromate, the initial pH of 5 to 6 being lowered during dyeing by adding acetic acid.  In the remaining examples, alternative chrome dyes are used or the dyeing is carried out with a casein or nylon fibre.

Abstract: 783,304. Frequency and phase discriminators. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 23, 1955 [March 26, 1954], No. 8454/55. Class 40 (5). A phase detector comprises a constant current source feeding three parallel branches, each containing a rectifier, i.e. one-way conductor, 5, 6 or 7, the sources 1, 2 whose relative phase is to be detected being included, one each in series with a rectifier 5 and 6 so that the output load resistor 8 is short circuited except during the interval when both 1 and 2 are both on positive halfcycles of oscillation. The mean output across resistor 8 is therefore proportional to this interval and the phase difference. The rectifier 7 prevents reverse current through the resistor 8 during negative half-cycles of sources 1 and 2. The sources 1, 2 may be critically coupled resonant circuits to one of which a frequency modulated wave is applied, the output then measuring the phase difference and therefore frequency deviation. Further, the rectifier 7 may be the base emitter impedance of a grounded emitter transistor across the collector circuit, the amplified demodulated signal being derived. Output variations due to variations in amplitude of the F.M. wave may be suppressed by adding a rectified component of the applied oscillations in series with the collector voltage.

Abstract: 548,431. Frequency meters. BRITISH THOMSON-HOUSTON CO., Ltd. July 4, 1941, No. 8474. Convention date, July 6, 1940. [Class 37] A meter adapted to measure small variations of frequency from a normal, and to be independent of voltage changes of the frequency-source, comprises a D.C. instrument 17 and rectifier 16, preferably in the same casing, arranged in a tuned circuit comprising a capacity 14 and inductance 15 energized from one secondary 12 of a saturated-core voltage transformer. A 'further secondary 13 applies through a transformer 18 a bucking voltage to the resonance-circuit, and also lights an indicator lamp 19. Fig. 3 shows one means for operating the meter. The circuit is tuned to provide a sharp peak in current curve A<1> at normal frequency of 60 and to fall off steeply on either side to 59 and 61 cycles, and the bucking voltage B<1> is arranged exactly to neutralize the tuned current at 60 cycles at which the instrument reads zero. Any departure from normal causes the bucking current to deflect the needle and as the curve A<1> may not be symmetrical two scales are provided, one for increase and the other for decrease. In order to ascertain which scale to read, a push button 20 is arranged to short-circuit part of the inductance 15, having for effect to move the curve A<1> to the left, the scale to be used being indicated by whether the needle moves up or down. By using the push button 20, the lamp 19 can be dispensed with. In Fig. 2 (not shown) is indicated a resonance-curve the peak of which is just past 61 cycles so that the tuned-circuit current operates the needle over the whole scale, and reference is made also to one in which the bucking current operates over the whole of a single scale. In a further form, Fig. 5 (not shown), the output of winding 13 is compared with that of the tuned circuit of a two-coil differential instrument.
