IPC: C09B44/10
Filed: 1956-06-22
Abstract: Textile materials of polymers or copolymers of acrylonitrile are dyed in an acid, neutral or weakly alkaline bath with a basic azo dyestuff of the formula <FORM:0787891/IV (b)/1> in which R is an alkyl, aralkyl, aryl or cycloalkyl group, n is 0 or 1, X is a divalent atom or a divalent group which makes up the nitrogen-containing ring to a 5- or 6-membered ring, Y is a radical of an aromatic amine or enamine capable of azo coupling and Z is an anion.  Dyeing may be effected at 100 DEG  C. or above. In a modification, the dyestuff may be added to the polymer solution from which the fibres are spun.  Numerous examples are given.  The dyestuffs may be obtained by the oxidizing condensation of hydrazones of heterocyclic ketones of the formula <FORM:0787891/IV (b)/2> with aromatic amines or enamines capable of coupling by the action of alkylating agents on azo dyestuffs of the formula <FORM:0787891/IV (b)/3>

IPC: B23K11/00
Filed: 1925-08-04
Abstract: 254,127. Reeson, J. N. Aug. 4, 1925. Uniting by fusion.-In butt or lap welding the plates or sheets of structures such as tanks, vessels, gas holders, &c. in such a manner as to avoid the distortion or internal stresses caused by the local expansion and subsequent cooling of the joint, the plates &c. are first connected together so as to permit of a certain freedom of expansion, are next strutted outwardly adjacent to the joints, and are then welded and the strutting appliances then released so as to allow the plates to contract. The plates b of a circular tank or gas holder are first supported from the flange ring a so as to hang in the form of qurtains, and the lapped edges are connected together by bolts passing through holes therein of larger diameter than the bolts. The plates are then strutted outwards near the horizontal joints until the bolts reach the edges of the holes, by planks e or metal strips pressed out by wedges or screws f passing through girders g secured to posts h. After welding by the electric arc with fusible electrodes the planks are released and the bolts removed. The bolt-holes are subsequently filled up, preferably with deposited metal. The vertical joints or oblique joints are welded in a similar manner. In place of first connecting the plates by bolts magnetic clamps may be used.

At a transfer station 10 for transferring articles 89 from long carriers 88 of endless-chain conveyer 6 to short carriers 200 of endless-chain conveyer 8 by means of holders 28 (as set out in Specification 854,436), steadying means 100 are provided to prevent the carriers 88 from swing- ing, so as to aid the transfer. Thus, sprockets 56 and 18 and disc 22 move together as a unit round fixed shaft 14 so that chain 6, chain 8 and material holders 28 accordingly rotate round the shaft 14 as a unit, so as to permit holder 28 at point 17 to engage article 89 on carrier 88 and the article to be carried round till at point 21 it is transferred to carrier 200 of chain 8. The steadying means 100 comprises twin synchronous chains 102, 114 of which chain 102 engages with and is driven by chain 6 and in turn drives chain 114. Chain 114 carries forks 120, each of which engages a carrier 88 to prevent the latter from swinging and is swung about axis 126 into engagement with a carrier by cam-track 128, the track bearing on fingers 122 secured to fork 120.

Abstract: 1,222,314. Naphthyridine dione dystuffs. ALLIED CHEMICAL CORP. 17 April, 1969 [30 April, 1968], No. 19777/69. Heading C4P. Naphthyridone-dione dyestuffs are prepared by heating an optionally substituted indigo with an arylacetylhalide in presence of 0À5 to 3À0 mol. of an inorganic acid halide per mol. of indigo compound and in the presence of an aroyl halide, the reactants being free from substituents which would produce watersolubilizing groups in the products. The reaction with the aroyl halide may be a second stage reaction the first stage taking place above 85 C. and the second above 135 C. The preferred inorganic acid halide is thionyl chloride and the preferred aroyl halide is benzoyl chloride. An organic liquid boiling above 135 C. may be used as diluent. Comparative Examples 2 and 12 describe a similar process without using the inorganic acid halide and Example 10 similarly uses an aliphatic acid halide instead of an aroyl halide with lower yields. The dyestuffs are used to pigment viscose, cellulose ester, superpolyamides and polystyrene.

Hand-stamps; inking-apparatus.-A hand-stamp which can be adjusted for printing different numerals, or other indications, and is fitted with a self-inking pad, is so constructed that this pad is kept out of contact with the printing-surface during its adjustment to bring a different numeral &c. into printing position. As shown in Fig. 2, the stamp 14, which is formed with ten numerals, is carried by a sliding frame 12 mounted in an outer casing 11 and maintained normally in a raised position by springs. In this position, a pivoted ink-pad 31 carried by a spring-controlled arm is arranged so that the stamp 14 can be rotated by bevel and spur gearing operated by rotating a handle 16 without contacting with the pad. On depression of the stamp 14 by acting on a knob 17, the pad 31 is first caused to ink the stamp, and is then moved therefrom by the action of a pin 34 on the stamp frame 12. As shown in Fig. 4, the pad 31 is normally in contact with the stamp 14, and is moved therefrom during its adjustment by means of a spring 35 which grips the shaft of the stamp frictionally and' is fitted with arms 35<11>, 35<1> which press respectively on a stop 36<1> on the frame 12, and on the inking-pad support, and trip the latter.
