Patent GB-866443-A (GB)
Title: New trisazo cupriferous dyestuffs and their method of preparation
Inventor: JIROU MARCEL
Filed: 1958-11-14
Abstract: The invention comprises copper complexes of dyes of formula:- <FORM:0866443/IV(c)/1> where R is the residue of salicylic acid, R1 is a monosulpho-2-hydroxy-1-naphthyl, monosulpho-1-hydroxy-2-naphthyl or acylamino-monosulpho-1-hydroxy-2-naphthyl residue and X is H or SO3H, the divalent copper atom being attached through the OH groups of the #s1, #s-dihydroxyazo grouping in the proportion of one atom of metal per mol of dye.  The dyes are made by dealkylating-metallization of dyes of the above formula where OH is replaced by O alkyl.  Excess coppering agent is usually required which results in some metallization of the salicylic grouping.  This chelation is destroyed e.g. by using sequestering agents such as the tetrasodium salt of ethylene-diamine-tetra-acetic acid, to provide readily water-soluble dyes.  Specified acylamino groups are acetyl-, benzoyl-, ethoxy-carbonyl- and methoxyethoxy-carbonyl-amino and H2NCO NH which may be substituted on the NH2 group. The dyes colour vegetable fibres.  Examples are provided of the preparation of the dyes and their use in dyeing cellulosic fibres in green shades.

Abstract: 841,391. Treating carded webs. CARDING SPECIALISTS (CANADA) Ltd. July 16, 1958 [Nov. 26, 1957], No. 36777/57. Class 120(1). Cotton fibres are passed from the doffer of a carding engine through ironing rollers followed by further rollers that exert a drafting action. From the doffer 10, the carded web passes between smoothly ground ironing rollers 24, 26 that may be heated and may be provided with scraper blades. To compensate for deflection under pressure, these rollers may be slightly convex or may be arranged with their axis slightly inclined as described in Specification 697,106. From the rollers 24, 26, the web passes to conventional drawing-off or calender rollers 16, 18 that rotate with higher surface speeds than the ironing rollers 24, 26 to produce the drafting effect. Two or more pairs of ironing rollers may be used employing successively increasing surface speeds. In an alternative form, an ironing roller may have several rollers pressed against it.

An apparatus for dip soldering comprises a solder bath, a heater for maintaining the solder molten, means to lower an article into contact with the solder and to raise the article from the solder, means to move the article horizontally in contact with the solder and means to jerk the article when clear of the solder to remove excess solder. A base 1 carries two columns 3 on which a frame comprising sleeves 8 and horizontal members 9 is movable vertically by a rack and pinion device operated by a handle 12. A carriage 13 movable along the members 9 by a rack-and-pinion operated by a wheel 15 pivotally supports at 17 a holder 18 comprising a fixed aluminium support 23 and a movable aluminium support 22. In operation with a printed circuit panel 29 to which the leads of components are to be soldered, held in the supports 22, 23, the frame 8, 9 is lowered to bring the panel into contact with the solder in the bath 25. The panel is moved horizontally to and fro for 5-12 seconds by rotating the handle 15. On raising the frame 8, 9 to lift the panel from the solder a member 31 on the support 23 engages a pivoted member 27 on a column 3 and the holder 18 rotates on the pivot 17 and tilts the panel to allow solder to flow off the panel. Further upward movement of the frame 8, 9 allows the member 31 to clear the member 27 and a spring 21 jerks the frame into the horizontal position against a stop 20. The solder is heated by a coil, temperature controlled by a cut-out 28.

Abstract: 1454624 Watches SUWA SEIKOSHA KK 28 Aug 1974 [30 Aug 1973 10 Sept 1973] 37597/74 Heading G3T In an electric timepiece e.g. driven by a stepping motor 11, one of the hands may be set to a datum position, e.g. zero, or to the nearest of a plurality of such positions by depression of an externally operable member 46 which causes a hammer 42 to engage an abutment member 31 and displace it to a predetermined position which is adjustable. As shown wheel 30 is a fourth wheel and carries a second hand; it is driven by rotor pinion 17 via an intermediate gear 26, 27. The member 31 is a heart-piece adjustably fixed on the wheel 30 by an eccentric pin 32, but alternatively an eccentric pivot 43 for the hammer may be used. The motor 11 comprises a stator 16 having poles 22, 23 and a coil 24 which receives alternating pulses from a quartz oscillator 10 via a frequency divider 12 so that permanent magnetic rotor 13 is turned through 180 degrees each second. The hammer 42 also actuates a reset switch 51 which ensures that the motor does not receive an effective pulse until one second later if the datum position is zero seconds, or is advanced as button 46 is released if the datum position is fifty nine seconds. There may be a plurality of datum positions e.g. for setting to the nearest ten seconds; the heartpiece may therefore be on a different wheel of the train Fig. 7 (not shown) or replaced by a star wheel Fig. 8 (not shown). The arrangement may be used for setting a minute or hour hand.

Alternatively the finger may serve as the cutter. A slot may be provided in one of the beds which co-operates with the circular cutter to assist in the severing of the loops. The machine may be a cylinder-and-dial machine.

Title: Improvements in or relating to the determination of moisture content
Inventor: BRIGGS JOHN NIGEL
IPC: G01N22/04
Filed: 1964-09-21
Abstract: 1,114,157. Determining moisture content. ASSOCIATED ELECTRICAL INDUSTRIES Ltd . Sept. 20, 1965 [Sept. 21, 1964], No.38380/64. Heading G1N. Apparatus for determining the moisture content of a material by measuring the attenuation of a beam of modulated microwaves directed through the specimen is compensated for temperature variations by means of a circuit including a temperature sensitive resistor. Oscillations at 10000 Mc/s modulated at 3200 c/s are passed through the specimen and a variable attenuator the output from which is detected to produce an audio frequency signal. This is amplified and rectified and the resulting D. C. voltage is compared with a reference voltage. Any error signal is amplified and applied to a reversible motor which adjusts the variable attenuator and also the slider of a potentiometer to give an output voltage Fig. 1 (not shown). The sample and variable attenuator may be replaced by a standard attenuator for calibration. The temperature of the specimen is detected by a thermistor TH1 connected in a bridge circuit with Zener diode MR1. At balance transistor VT1 passes a constant current through potentiometer 33 the slider of which is positioned by the motor driving the variable attenuator. Variation of temperature unbalances the bridge to vary the current through 33. The gangs of a two-ganged potentiometer may be connected one at each end of potentiometer 33 so that the circuit may be adjusted for specimens having a different value of A o  in the relationship where W is the wetness of the specimen f (T) is a function of temperature A is the attenuation and Potentiometer RV3 is adjusted in accordance with k 2  and variable resistor RV2 is adjusted in accordance with k 1 . Adjustment for different values of W 0  may be made by adding a constant voltage from an adjustable source Fig. 5 (not shown) to the potential 1 difference across the output potentiometer, or by passing a constant current from an adjustable source Fig. 6 (not shown) through the output potentiometer, and adjusting the sources in accordance with A 0 . Alternatively the potential difference across the output potentiometer may be applied to a buffer amplifier (e. g. of the long tailed-pair type) and the output adjustably biased. The apparatus may be modified by comparing the output from detector 19A (Fig. 7) with the output from a detector 19B connected to reference attenuator 11. The amplitude and phase sense of the output from transformer 55 is indicative of variations in attenuation in the specimen and the output is applied to a phase-sensitive demodulator controlling servomotor 31 to compensate for such variations. The transformer may be dispensed with if the polarity of one detector 19B is reversed.
