Abstract: 532,287. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and COLLEY, E. Aug. 24, 1939, No. 24383. [Class 40 (iv)] In a selector which hunts for an idle outlet marked by battery on the test terminal, the test relay is operated before the hunting motion and is released by differential action when an idle outlet is encountered. In Fig. 1, test relay H energizes and locks over winding (i) upon the operation of dialling relay C, and when the latter falls back and closes the self-interrupting circuit of the rotary magnet R, winding (ii) of H is connected to the test wiper P. To ensure quick release by current flow over wiper P, winding (ii) has more ampere-turns than winding (i) and the relay may have a nickel-iron core. On the relapse of H, relay C re-operates, switches through and again connects up H, which holds to ground fed back over wiper P and maintains C. The selector restores when H, C fall back by resumption of its rotary motion. In the modification shown in Fig. 3, test relay H energizes over winding (ii) and locks over winding (i), and is subsequently released by current in the reverse direction through winding (ii). Other arrangements, Figs. 2, 4 (not shown), are described in which the selector is marked idle by the absence of ground on the test wire instead of by the presence of battery, as in Figs. 1, 3.

Abstract: Materials of polyolefins, especially textile materials comprising stereoregular polypropylene, are dyed in a process which comprises applying thereto a metal salt, other than an alkali metal salt, of an organic acid or a metal co-ordination compound and a water-insoluble dye containing metallisable groups. Specified metal salts are copper benzoate, aluminium benzoate, aluminium adipate, aluminium phthalate, aluminium stearate, calcium oleate, magnesium stearate, copper naphthenate or zinc octoate as well as co-ordination complexes of salicylaldoxime, 8-oxine, salicylic acid, glycine, o-hydroxyacetophenone oxime, ethylene diamine, acetylacetone, benzoylacetone, o-hydroxyphenyl-dodecyl ketone oxime, phenylnitrosohydroxylamine and 5-dodecyl-8-hydroxyquinoline.  The dyestuffs may be from the azo, anthraquinone or heterocyclic series and include dyes containing hydroxy alkoxy, carboxy or carbalkoxy groups in ortho position to an azo linkage.  Preferably the dyes also contain at least one straight or branched chain alkyl group of at least 4 carbon atoms or at least one cycloalkyl group.  The preferred anthraquinone dyes are the derivatives of dihydroxy-anthraquinones, especially alizarin and its derivatives. Many dyestuffs are specified.  The dyestuff and the metal compound may be applied in either order from solutions in organic solvents, aqueous solutions of organic solvents, emulsions but preferably from aqueous dispersions or solutions.  Known dispersing agents may be employed e.g. anionic, non-ionic or cationic agents; those specified being sulphonated naphthalene-formaldehyde condensation products, oleyl sulphate, ethylene oxide-fatty alcohol condensation products and cetyl-trimethyl-ammonium chloride. Dyeing may be effected at 65-100 DEG C. or from 100-125 DEG C. at superatmospheric pressure and metallisation may be effected at 60-100 DEG C.  In the preferred embodiment, the polyolefin material is first treated with the metal compound which desirably contains an aliphatic group of at least 4 carbon atoms, rinsed and then dyed.  Examples are given.

In a work-feeding device for a guillotine machine for cutting paper, metal foil and the like, the carrier for the saddle is reciprocated by means of an electric motor 10 provided with fast and slow forward speeds and with a reverse speed. The carrier is moved along a slot 2 in the cutting table 1 by means of a screwed lug 6 thereon engaging a screwed spindle 7 having thereon a pulley 9 which is driven by the motor. The carrier is guided in its movement by means of a lug 5 beneath the table. In a modification, Fig. 4, the drive to the carrier has incorporated therein a magnetic brake 11 which comes into operation when the motor is switched off. Limit contacts are fitted at the ends of the slot and switch off the motor automatically when the carrier reaches either of its end positions. To pre-adjust the feed to cut off a given length, an endless belt 12 running over loose pulleys 13, 14 is connected to the carrier, and the end 17 of an adjustable lever 15 pivoted on the axis of the pulley 14 is adapted to engage a contact 18 on the table so as to switch off the motor. The feed switch is coupled with a switch for the cutting apparatus in such a manner that when both the switches are actuated, the feed ceases and the magnetic brake is energized, thus controlling the motion of the cutting-knife 19.

Wire from storage reels 17 is wound on bobbins in the position of bobbins 27,. and when a predetermined number of turns has been wound the spindle carrying the bobbins is moved to the position of the spindle 15, a fresh spindle 16 carrying empty bobbins 27 being placed in position for winding; the wire between the full bobbins 18 and the reels 17 is then secured to the bobbins 27 by pieces of adhesive tape 28 and passed through grooves 13 in the flanges 11, the wire between the bobbins 27 and the bobbins 18 is broken, and winding is resumed on to bobbins 27. A tube of insulating material is slid over the end of wire in the groove 13 of each wound bobbin and the tube forced into the groove 13. If the wire is thin, two thicker wires may be soldered on to the two free ends and passed through holes in adhesive tape covering the finished coil.
