Patent GB-819585-A (GB)
Title: Colouring cellulosic textiles
Inventor: RATTEE IAN DURHAM
IPC: D06P/
Filed: 1956-04-18
Abstract: Cellulosic textile materials are dyed or printed by applying an acid-binding agent in aqueous solution or suspension and then applying an aqueous solution of a monoazo or polyazo dyestuff which contains at least one ionogenic solubilizing group and also contains at least once a primary or secondary amino group carrying as N-substituent a 1 : 3 : 5-triazine radical containing at least one halogen atom attached to a carbon atom of the triazine ring. Specified acid-binding agents are caustic soda, caustic potash, magnesium oxide, sodium and potassium carbonates and bicarbonates, trisodium phosphate and sodium metasilicate. The acid-binding agent and the dyestuff may be applied in two padding operations or successively from a single bath. Alternatively, the acid-binding agent may be padded on to the textile and the dyestuff applied by printing.  A subsequent heat or steam treatment is preferably applied.  The dyebath or paste may contain the usual assistants such as sodium chloride, sodium sulphate, sodium alginate, cellulose ethers, urea, starch and locust bean gum.  Numerous dyestuffs are specified and numerous examples are given.

Filed: 1946-04-17
Abstract: 610,891. Boxes. SCHALL, E. April 17, 1946. No. 11900. [Class 18] [Also in Group XXV] A box a has two lids b, c, the uppermost lid in either position of the box being opened by pressure on a plunger d. The plunger is secured in position by a spring e on which is pivoted a cross-bar g, which has a hook at each end which engages a lid. In one form a hinged arm h falls by gravity between the cross-bar and a fixed bar i and prevents movement of the lower end of the cross-bar when the plunger is pressed. In a modification the arm h is replaced by a ball arranged to drop in a guide channel.

Abstract: 1,182,455. Coking pitch. CHARBONNAGES DE FRANCE. 14 March, 1967 [14 March, 1966], No. 11944/67. Heading C5E. [Also in Division C1] Carbons produced by carbonization of pitches having a highly aromatic hydrocarbon content are hardened and their graphitizibility reduced by adding from 10 to 16% by weight of ammonium sulphate as a solid or in solution to the pitch before its carbonization. Suitable pitches are those obtained from the distillation of high temperature coal tars or cracking bitumens. In one example the mixture is carbonized at a speed of 1‹ C. per minute in a neutral atmosphere up to 550‹ C. and is then carbonized at a heating speed of 3‹ C. per minute up to 1000‹ C. and is maintained at that temperature for half an hour. The hard carbon product has high electrical resistivity and may be used as a reducing agent in electro-metallurgy, as a furnace heating element, as resistance granules in graphitization furnaces, and as raw material to prepare active carbon.

Filed: 1929-04-19
Abstract: 331,948. Houdaille, M. A. M., and Etablissements M. Houdaille. April 19, 1929. Fluid friction vibrationdampers of the rotary or oscillating type are provided with a thermostat utilizing the volumetric expansion of a fluid or semi-fluid to control the flow of the damping-fluid, the thermostat being of the cylinder - and - piston type and arranged along the axis of the rotating elements. When the viscosity of the damping-fluid varies in accordance with changes of temperature, the effective size of the leak orifice is correspondingly varied by the thermostat control so as to ensure a constant damping effect. The apparatus shown in Figs. 2 and 3, is of the type disclosed in Specification 299,798 and includes a movable vane secured to the shaft 15 and oscillating in a circular casing within limits determined by a semi-circular abutment 16. The chambers 13 on opposite sides of the vane are connected by passages 17, the flow through these passages being controlled by a leakage orifice in the end of a piston rod 18, the other end of which is provided with a piston 10 working in a cylinder filled with fluid, for example vaseline. A spring forces the piston 10 into its cylinder. In the modification shown in Fig. 1 the end of the thermostat piston-rod 19 bears against a ball 4 which rests in a conical recess in the end of an expansible valve 3 by which the flow of damping-fluid is controlled. When the temperature rises the piston-rod 19 is forced towards the left and the walls of the valve 3 are expanded so as to reduce the area of the leakage space between the outside of the valve and the passage in which it is placed.

Filed: 1922-05-02
Abstract: 199,555. Holt, H. E. S. May 2, 1922. Transferring articles to conveyances in motion. -In transferring mailbags or like articles from the ground to aircraft in flight a coupling-member such as a tapered weight o is attached to the end of a hoisting-rope n, lowered from the aircraft and, by means of a guide structure d, is guided into engagement with a coupling - member b attached to the load. In the construction shown in Fig. 1 the structure d is in the form of a conical tube with a wide entrance and a slot along its upper edge, and guides the weight o into gripping engagement with the tapering tube or coupling-member b attached by a cord c to the mail-bags j, j<1>, j<2>. In order to relieve the aircraft from excessive shock due to the inertia of the load, the latter may be divided into several portions j, j<1>, j<2> which are successively lifted, or the supporting platform a may be arranged to release the load with an initial velocity. As shown, the platform a is mounted on a pivoted bar g connected to a spring h but normally held by a catch i so that, when the latter is released by the movement of the coupling-member b, the platform and load are actuated by the spring h. A single cord c provided with a seal may be arranged to close a number of mail-bags by passing it through holes in a socket m, Fig. 4, at one end of a securing-band k and through holes l at the other end of the band. The platform a and guide structure d are mounted on a pillar f revoluble on a base e so as to be adjusted according to the direction of the wind. The rope n, Fig. 2, is prevented from trailing at too great an inclination to the vertical by an inclined vane p connected to a parachute r. This Figure also shows a modified form of guide-structure consisting of a base d<2> mounted on wheels d<4>, converging sides d<1> and a pivoted end plate d<3>.

Abstract: 248,594. White, A. E., (Wellman-Seaver- Morgan Co.). May 12, 1925. Valves controlled by pilot or relay valves ; casings.-A valve of the kind in which the main valve member slides in an inner casing arranged axially in the pipe line has the nose of the valve member and the rear part of the inner casing formed with a convex longitudinal curvature. The valve is actuated by pressure derived from the centre of the conduit through a pipe 20 acting on a piston 15 arranged to work in a cylinder 17 mounted in the inner casing. The inner casing is attached to the outer casing by webs 12 which are extended to form guides for the valve member and the lower one is widened with a stream line contour and is formed internally with two passages 23, 24 leading to the space 17<a> behind the piston and the interior of the valve member respectively. A pressure equalizing pipe 18 fitted with a stop valve 18<a> connects the passage 24 with the main conduit beyond the valve seat, one or both ends of the pipe being below the axis of the valve. Fluid pressure under the control of an auxiliary valve is admitted to or exhausted from the chamber 17<a> through the passage 23 and a pipe 21 secured to the cover 25 while a pipe 22 arranged within the passage 24 serves the chamber 17<b> on the other side of the piston. Pressure is admitted to the chamber 17b through a port 27 in the side of the cylinder adapted to be obturated by the piston and through a port 27a in the end of the cylinder fed through a pipe 26 provided with a non-return valve 29. Pressure is exhausted through the port 27 alone so that the closing movement is cushioned by fluid trapped in the cylinder. The indicator rod 34 is connected to the control valve lever 36 and is moved by a stanchion 30 secured to the valve member just behind the valve face. This stanchion is guided and protected by depending walls 3 formed on a cover 32 detachably secured to the casing. In a modification the stanchion is guided by a keyway on the cover and is protected by a single wall on the cover co-operating with one of the ribs 12. Specifications 182,156 and 182,414 are referred to.
