Title: Process for dyeing nitrogenous fibres
IPC: D06P1/607
Filed: 1959-03-11
Abstract: Nitrogenous fibres capable of being dyed with acid dyestuffs, such as wool, silk and polyamide fibres, are dyed or printed from an aqueous medium containing a reactive dyestuff containing at least two sulphonic acid groups and compound containing at least one basic nitrogen atom to which is bound at least one residue containing a polyglycol ether chain, the molecule of said compound containing at least 3  <FORM:0878021/IV(c)/1> groups and at least 4 carbon atoms not belonging to such groups. The dyestuffs, which contain the usual reactive groups, may be of the stilbene, perinone, peri-dicaroxylic acid imide, nitro, triphenylmethane, phthalocyanine, anthraquinone and azo series. Suitable nitrogenous compounds are the reaction products of at least 3 molecular proportions of an a  : b -alkylene oxide with one molecular proportion of an organic compound containing at least one basic primary or secondary amino group, or a basic tertiary amino group and an alcoholic hydroxyl group, or salts or quaternary ammonium salts of those compounds, those of the formula:- <FORM:0878021/IV(c)/2> wherein R represents an aliphatic hydrocarbon radical of at least 12 carbon atoms, m and n being 1 or 2 and p, q and r being whole numbers such that p+q+(m-1)(n-1) is at least 3 and at most 20, or of the formula:-  <FORM:0878021/IV(c)/3> wherein R represents an aliphatic hydrocarbon radical of at least 12 carbon atoms and p and q are whole numbers such that p+q is at least 3 and advantageously 8-16, being particularly suitable. Esters of the above compounds with polybasic acids, such as phosphoric or sulphuric acid, may also be employed, as also may their water-soluble salts.  Dyeing is preferably effected in an acid medium containing sodium sulphate at a raised temperature or at the boil.  Printing, particularly of worsted tops by the slubbing method, may be effected with an aqueous paste containing also, if desired, a thickener such as tragacanth or British gum, an acid such as acetic acid, turpentine, hydrotropic substances such as urea and agents preventing reduction such as sodium nitrobenzenesulphonate, the prints being finally steamed. Numerous examples are given.

IPC: B23B29/034
Filed: 1916-06-16
Abstract: 104,603. Comings, W. R., (Mummert- Dixon Co.). June 16, 1916. Turning. - Rotary tool-heads have a forked tool-slide 20, Fig. 3, retained in a slot by a cover-plate 21, Fig. 5, fed by a screw held against end movement by a forked pin 33 and provided with a starwheel 36. The cutter is clamped at 26 in an inclined slot in the holder, a screw 28 provided for end adjustment. Feed is effected by a loose ring 40, which may be arrested and which carries two pins 38, Fig. 7, notched to engage a resilient pin 46 providing a backing which will yield in the event of overload. One of the pins 38 is fitted with a nut 51, by which it may be retracted and held inoperative. The cover-plate is recessed to receive a disk 54 fitted with a pilot 60, with a centre 62, Fig. 10, or with a bush 63 carrying a drill for forming a centre in the work. The feed-screw is recessed for a key at 53 for a quick return of the slide. In a modification, the pilot, centre, or drill 66, Fig. 11, is mounted in the bored end of the shank of the tool-head, the feed-screw is supported by an outer bearing 70, Fig. 14, and a screw and pad 71 provide for clamping the slide in an adjusted position.
Patent GB-472053-A (GB)
Title: Improvements in or relating to fluid control devices
IPC: A61C17/00
Filed: 1936-03-21
Abstract: 472,053. Retractive switches. PIEPER, A. F. March 21, 1936, No. 8522. Convention date, June 4, 1935. [Class 38 (v)] [Also in Groups VI, XI, and XXIX] A dental syringe or like fluid-control device comprises two tubular bodv members, one of which carries a nozzle and is movable with the nozzle longitudinally with respect to the other body member, the members being adapted for the passage of fluid therethrough and one of the members having means for electrically heating the fluid, circuit connections for the heating means the circuit of which is closed by the longitudinal movement, and valve means for controlling the flow of the fluid. Preferably the valve is opened by the aforesaid longitudinal movement just before the electric circuit closes. As shown, Fig. 6, one of the tubular body members consists of a casing 10 within which a valve-operating tubular body member 11 moves longitudinally, the member 11 carrying a heating unit enclosed in a housing 12. A tubular valve-supporting section 15 is disposed within the casing 10 and has one end resting on a tubular member 16 threaded within the lower end of the casing and adjustable therein to regulate the position of the section. The section 15 is provided with a seat 17 for a valve 18, engagement being promoted by a spring 19, the tension of which is adjustable by a nut 20. The valve is opened by swinging a pivoted lever 32 towards the casing. This causes a longitudinal movement of the member 11 with respect to the casing 10, the movement being transmitted to the valve by a valve-operating stem 24. At the same time the longitudinal movement causes a ring-shaped element 67 to contact with a movable resilient contact member 73, thus closing the electric circuit to the heater. The electric current passes from a wire 83, Fig. 9, through a nipple 47 a wire 70, the switch contacts 67 and 73, a wire 81 and a screw 54, Fig. 2, to a heating coil 59 returning through a tubular member 61, the casing 12, the casing 10 and a wire 84, Fig. 9. A lever 77 enables the heating to be stopped while the valve continues to allow fluid to pass. The fluid is delivered through a conduit 43, Fig. 9, and passes through the section 15, an annular channel 26, a slot 31 and a chamber 66 into the heating unit. It then passes around a tube 51 and through an aperture 51a into an annulus between the tube 51 and an inner tube 58 to enter an insulating tube 60 through which it passes in contact with the heating coil 59 to a nozzle 14. The unit 15 is capable of rotating together with the fluid supply conduit within the casing 10.

Filed: 1976-03-04
Abstract: 1530383 Uniform web forming CEFILAC 4 March 1976 [11 March 1975] 08673/76 Heading DIN A process for forming a non-woven web from particulate material comprises feeding particles at a solid volume flow rate of less than 2,000 cm<SP>3</SP>/m<SP>2</SP>/min over a substantial length of a conveyor belt 9 in a current of low speed air with local zones of turbulence giving the particles a vertical speed component substantially lower than their speed of free fall such that a homogeneous and isotropic aerated layer of more than 95% empty space is formed, this layer being compacted and densified into a web. The layer is formed inside a cowl, material being fed in e.g. from cyclones 1, the cowl containing oscilating distributor vanes 6 and baffles 7 and air jets 8 to provide the turbulence. Most of the air is exhausted at 10 and 11 upstream and downstream of the cowl while the remainder enters a suction box below the belt. A device 16. Fig. 2, with rotary combs 25, 26 removes peaks from the layer to give a uniform thickness. Removed material is sucked away through deflector 17 while air jets F1 and F2 from tubular members 20, 21 aid removal and clean the combs 25, 26. The device 16 can be elevated by screw 22 under the control of a thickness sensor 28, 29. The axis of device 16 may be inclined to give a thickness variation across the web. Roller 32 compresses the web aided by suction chamber 30. The web passes through a heater 37 which activates a thermo hardenable resin included in the web. Several cowls can be arranged in series to apply different layers or the cowl may have internal dividing partitions. Additional conveyer belts can be provided at the edges of conveyor 9 to give a U-section.
