Patent GB-794177-A (GB)
Title: Dyes of the nitrodiarylamine series
IPC: C09B51/00
Filed: 1955-05-16
Abstract: The invention comprises dyes of the formula: <FORM:0794177/IV (b)/1> where R and R1 are aryl radicals, one of which contains a carboxyl group, and a process of making them by reacting a 4-halogen-3-nitrobenzene sulphonyl halide with a compound of the formula R1-NH2 to produce a compound of formula: <FORM:0794177/IV (b)/2> (X being halogen) and reacting said compound with a compound of formula R.NH2 in presence of an acid-binding agent.  The aryl radicals may carry other substituents such as alkoxy, halogens, acylamino, hydroxy, acyl, hydroxyalkoxy, and hydroxyalkyl.  The products dye cellulose esters and ethers and nylon, and the dyed materials may be aftertreated with cationic heatcurable amine-formaldehyde condensates or with copper-containing fixative agents or with both (see Specification 794,179).  Blends of cellulose acetate with viscose rayon and nylon may also be dyed, using the dyes of the invention together with direct dyes for the viscose, and the dyes of the invention may be used with other cellulose acetate dyes. The dyebath is preferably acidic, made so with e.g. acetic or formic acids or ammonium sulphate.  Softening or swelling agents for cellulose acetate, e.g. the monobutyl ether of diethylene glycol or triethyl phosphate may be used.  In examples: (1) 4-chloro-3-nitrobenzene sulphonyl chloride is reacted in water with o-, m- or p-aminobenzoic acid, or with o-hydroxy-m-aminobenzoic acid to give the corresponding 4-chloro-3-nitrobenzene sulphoncarboxyanilides, which are reacted with aniline; (2) 4-chloro-3-nitrobenzenesulphonyl chloride is reacted with aniline to give the sulphonanilide, which is reacted with p-aminobenzoic acid. Further examples describe the dyeing of cellulose acetate, the aftertreatment of the dyed fabric with trimethylolmelamine, an organic amine hydrochloride, and formaldehyde, and the dyeing of a fabric comprising cellulose acetate, viscose rayon, and nylon with a mixture of 2-nitrodiphenylamine - 4 - sulphon - p - carboxyanilide, an azo dye, an anthraquinone dye, and a mixture of direct rayon dyes, followed by aftertreatment with trimethylolmelamine as above and with a copper fixative agent.

Title: Non-woven fabrics and methods of making them
Inventor: CROSBY DAVID WINSTON
IPC: D04H11/08
Filed: 1965-04-03
Abstract: 1,136,911. Laminates and laminating. ICI FIBRES Ltd. 11 March, 1966 [3 April, 1965], No. 14233/65. Heading B5N. A reversible non-woven fabric comprises a fibrous interlay 13 interposed between two layers 11, 16 each constituted by a bonded fibrous web, with some fibres from the fibrous interlay oriented through one of the bonded fibrous web layers as fibre tufts 27, and other fibres from the interlay oriented through the other bonded fibrous web layer as fibre tufts 30, the fibre tufts 27, 30 being set in position as a result of the bonding together of fibres in the fibrous interlay. The fibrous web layers are bonded by needle-punching and/or adhesive union between fibres produced e.g. by incorporating a bonding agent, preferably at discrete areas, in the layer during or after its fabrication. Alternatively the fibrous web layers include heterofilaments having latent crimp and a potentially adhesive component, the adhesive serving as a bonding agent for the layer when heat or a chemical medium is applied. The layers 11, 16 preferably have the stereoreticulate structure claimed in Claim 1 of Specification 1,073,181. The interlay 13 may be any loose assemblage of natural or synthetic fibres obtained, e.g. by carding, garnetting, air-deposition or fluid paper-making techniques, or may include fibres of a continuous filamentary structure. The interlay may consist of, or contain, fibres with a latent crimp which may be developed when the assembly is treated to bond the fibres of the interlay. The interlay may include thermoplastic resin in powder or sheet form to act as a binder on the application of heat, or may include heterofilaments containing a potentially adhesive compound developed by heat or a chemical medium. The fibres of the interlay, and hence of the fibre tufts may also have a latent crimp, which may be developed during bonding of the interlay, and as a result of such crimping the tufts may form a definite layer or layers at the exposed surfaces of the fabric. The outer layers 11, 16 may have the same or different composition and may be bonded by similar or different methods, and the interlay may have the same fibre composition as one or both of the layers, though it may for example have a different dye uptake. In a described method of making the fabric the layers 11, 16 with the interlay between them are fed to a needleloom where one set of tufts is formed and then to a second needleloom where the remaining tufts are formed. Alternatively one single-bed needleloom can be used for both sets of tufts or a double-bed needleloom can be used. After needle-punching the assembly passes through an oven where the fibres are crimped and the fibrous interlay bonded.

Title: Improvements in or relating to thermoelectric pulse generating devices
IPC: H01H61/06
Filed: 1960-04-25
Abstract: 909,248. Thermal switches. SWF-SPEZIALFABRIK FUER AUTOZUBEHOER G. RAU. G.m.b.H. April 25, 1960 [April 30, 1959], No. 14356/60. Class 38 (5). [Also in Group XXXVIII] A hot-wire operated flasher comprises an insulating base 1 carrying a support bracket 2 with a connecting lug 4. Riveted to the top of support 2 is a resilient lever 5 having a central tongue 8 cut out therefrom to carry a reinforcing lever 11 cranked to form a part 12 to which is insulatedly attached a heat-sensitive wire 13 anchored at its other end to a bracket 18 insulatedly carried on the support 2 near its base. The side arms of lever 5 are stiffened by bending up their outer edges and a C-spring 10 acts between the end of reinforced tongue 8 and the cross part 9 of lever 5 to produce snap action. The wire 13 is tensioned by a spring 29 acting on the part 12 of lever 11, and a coiled lead 14 connects wire 13 to terminal lug 16. The lever 5 carries two contacts 20 and 24 which cooperate respectively with a contact 19 formed on bracket 18 and a contact 25 carried by a member 26 insulatedly secured to support 2 and having a terminal lug 28. The contacts 19, 20 are thus in series with the wire 13 to produce an intermittent snap-action of the lever 5 when the circuit between lugs 4 and 16 is energized, while the circuit between lugs 4 and 28 (i.e. contacts 24 and 25) may be utilized to flash vehicle headlights. Due to the contact 24 being laterally offset from the longitudinal axis of the lever 5 a slight torsional movement of the lever is produced when contact is made, and this results in a wiping action between the contacts 24 and 25.

Title: Circuit arrangement for repeating current impulses in telephone systems
IPC: H04Q1/36
Filed: 1929-05-09
Abstract: 311,410. Telefonaktiebolaget L. M. Ericsson. May 12, 1928, [Convention date]. Automatic exchange systems.-A relay combination repeats impulses with a definite predetermined break period irrespective of the length of the break period in the impulses received. When the loop PS, Fig. 1, closed relay A energizes, connecting relay B which in turn connects relay C. Relay C breaks the circuit of B at 4 and connects slow release relay D completing the loop in the circuit SS. When impulses are sent over PS A falls back de-energizing C. When A pulls up B operates, first making a locking circuit for itself at 3 to ensure full energization, then completing the circuit of C and breaking the loop of SS. Relay C breaks the circuit of B which relay de-energizes after a time determined by the value of the resistance R. When B falls back the circuit SS is re-made. Further pulses are repeated in a similar way, the break period in the loop SS, being the release period of B, is independent of the break period in PS. If the impulse received has a very short make period and a long break period, relays B and C may interact and chatter. This is prevented by the modification in Fig. 2, where relay C has two windings. Contact 3 again closes before 5 and 8 and consequently opens after them, but the circuit is arranged so that if contact 1 is open before contact 5, relay C is held until contact 3 has released and the completion of an unwanted circuit through B is prevented.
