Abstract: <PICT:0350556/IV/1> <PICT:0350556/IV/2> In apparatus for the wet treatment of textiles, of the kind in which the textile material in the form of hanks, skeins, &c., is suspended over a tank of treating liquid by means of a hollow tubular support formed with an outlet opening or perforations through which the liquor delivered to the support by a pump is discharged against the hanks &c. suspended from the support, the support is maintained in a fixed position whilst a movable device is provided for changing the position of the hanks &c. relatively to the support.  The supporting members 13, preferably formed with the outlet holes 20 in the upper surface, are supplied with liquor through the system 22, 21 by a pump 23.  The hanks 12, put into position over the end 30, embrace also a member 26, which spaces the sides of the hank apart, being periodically revolved, about the centre of the supporting member as an axis, by the gear 34, 37, thus shifting the position of the hanks.  The liquor emerging from the outlet opening or holes flows down the hank enveloping it in a film of liquor.  Several alternative forms of supporting members are shown and described.  In one form a slot, extending longitudinally of the member, may have its edges turned inwardly to form baffles, a number of other plates being positioned to divide the emerging liquor into a number of streams. Alternatively a perforated hollow tubular member may be contained within the slotted supporting member, the liquor being supplied to the tubular member.  To increase the action of the liquor, supplementary spraying means may be employed consisting of a deflector plate 50, Fig. 7, which may be formed integrally with the member 53, which periodically rotates to shift the position of the hanks, the liquor emerging from the holes 48 being deflected outwardly against the sides of the hank.

Abstract: 568,326. Colour television; cathoderay tubes. TRIGGS, W. W. (Farnsworth Television & Radio Corporation). May 26, 1943, No. 8416. [Classes 39 (i) and 40 (iii)] In colour television, the several colour signals are keyed into separate sections of an electron multiplier 28, Fig. 4, by separate channels 84, 85, 86 triggered in succession by keying pulses 68, 75, Fig. 5. This enables the volume of the separate colour signals to be separately adjusted by potentiometers 80, 81, 82. The blanking signals may also be keyed into the electron multiplier through a channel 88. The electron multiplier 28 is situated in a dissector tube 20, Fig. 3, behind the transparent window 23 through which an image is projected on to a cathode 21 at the other end of the tube 20. The electron stream is focused by a coil 22, and the scanning of the cathode 21 by an aperture 30 is performed by coils 32, 34 energized by scanning generators 27, 29. The aperture 30 is formed by a cup 31, Fig. 4, in the electron multiplier 28, and the bottom of this cup has a small aperture 33 adjacent a third aperture 36 facing the first multiplier element 35. Specification 555,179 is referred to.

[Also in Group XXV] A spigot and socket connection for permanently securing a handle 13 to a vessel 12, Fig. 1, comprises a leaf or wire spring arrangement let into one or more radial recesses in the spigot or socket in such a manner that whereas the spigot is readily inserted into the socket any attempt to withdraw the spigot causes said spring arrangement to bite into the surface that would otherwise slide past it. In Fig. 4 the leaf spring 16 is in a radial recess in a spigot b and is flexed by a shoulder 18 to press against the internal surface of the socket a. Any attempt to move the spigot b to the right will be prevented by the spring 16 biting into the socket a. Many alternative forms and arrangements of the spring 16 are described and illustrated. The spigot and socket may each have aligned recesses to receive a key to prevent relative rotation.

Title: Methods of increasing the dispersibility of mica in powder form
Inventor: CHATFIELD HERBERT WALTER
IPC: C09C1/40
Filed: 1959-03-13
Abstract: The dispersibility of mica when mixed or ground in liquid media is increased by first mixing the mica in powder form with lauric, myristic, palmitic, stearic or behenic acid or hydroxy stearic acid or a salt of one of these acids.  The mica may be mixed with a solution of the fatty acid in a solvent, the solvent subsequently being evaporated, or a dispersion of mica in water may be mixed with an aqueous solution of an alkali metal salt or soap of the fatty acid, after which the mica is filtered off, washed, and dried.  In examples, mica is mixed with solutions in butyl alcohol and xylol of stearic acid, lauric acid and myristic acid, and the solvent evaporated, and dispersions of mica in water are mixed with aqueous solutions of sodium stearate, potassium stearate, ammonium stearate, sodium laurate and potassium palmitate, the mica filtered off, washed and dried.

Title: An improved yarn detecting mechanism for textile machine stop motions
Inventor: MARTIN CHARLES STANLEY
IPC: D04B35/10
Filed: 1952-06-11
Abstract: 716,549. Stop-motion. TRIP-LITE, Ltd. June 11, 1952 [April 16, 1951], No. 8767/51. Class 120(2). [Also in Group VIII] A stop-motion for a textile machine comprises a pivoted support 7 over which the yarn passes and which is held by a spring 25 against a bar 33. Freely pivoted feeler arms 12 rest on the yarn passing over the support so that in the event of yarn breakage or a decrease in tension the feelers drop to cause an electrical contact to be engaged thereby effecting stoppage of the machine. Similarly, if the tension of the yarn is unduly increased, the support 7 is pulled down permitting the arms 12 to drop to stop the machine as before. The spring 25 is connected to a crank 4 of the support whereby an over-centre movement is achieved so that after the support has passed the central position it is urged into an extreme position simultaneously permitting the yarn to slip from it. Variation in the tension of the spring 25 influencing the support 7 is achieved by turning a knob to wind up or release a cord 28 attached at one end to a spindle 26 on which the knob is secured.

Abstract: 539,170. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. May 17, 1940, No. 8840. Convention date, Aug. 5, 1939. [Class 40 (v)] In a negative feedback amplifier having a gain regulator in the feedback path, means are provided to ensure that the deviation from an ideal amplifier for a finite value of feedback is constant over the frequency range amplified. Fig. 1 shows a line amplifier for carrier frequencies of 12-60 KC. in which gain is adjusted by varying the tapping 23, 24, 25 on a feedback potentiometer arranged across one diagonal of output bridge Rp, Z21, R, Z11, and by a condenser potentiometer formed by the manually controlled condenser GC and the condenser GR operated by pilot wire control 26 and trimmer condensers TR, tr. The gain is also adjustable by tap 36 on the input transformer. A network N is connected in series with the output transformer to stabilize the feedback loop against oscillation at frequencies above the operating band as described in Specification 525,126. When tap 23 is used switches 56, 64 are closed and when gain is reduced by adjustment to tap 24 switch 64 is opened and in further gain reductions tap 25 is used and switches 55, 56 are in the positions shown. Further gain reduction is effected by tap 36 on the input transformer and closing switch 38. Switch 64 short circuits a network 54 giving local feedback and switch 56 a similar network 57 associated with the output stage, the switch 55 ensuring correct grid bias for this stage. Alternatively network 53 may 'be replaced by the network shown in Fig. 4 and the intervalve coupling shown on Fig. 5 may be used so as to correct for the amplifier deviation due to the Á# effect. The Specification gives a mathematical analysis and phase and gain curves showing the deviation produced by the Á# effect for low values of Á#.
