Title: Improvements relating to the finishing of textile yarns and fabrics
IPC: D06P1/00
Filed: 1936-03-21
Abstract: Cellulosic materials are rendered crease-resisting, shrink-resisting and have an increased fastness-to-washing of relatively fugitive dyestuffs by impregnating with formaldehyde and an aromatic sulphonic acid, drying, washing and drying.  The dyestuff may be applied locally by spraying, printing or stencilling prior to or together with the acid; local dyeing effects may also be produced by the local application, prior to the formaldehyde treatment, of a substance which will neutralize the acid and prevent fixation of the dyestuff. Preferred acids are benzene and naphthalene sulphonic acids, amino sulphonic acids, hydroxy sulphonic acids, halogen substituted sulphonic acids, nitro-amino sulphonic acids, aminohydroxy sulphonic acids and quinone sulphonic acids.  Dyestuffs which can be fixed are direct and acid dyestuffs, basic dyestuffs without their usual fixing agent, water-soluble mordant dyestuffs without metallic mordant and water-soluble acetate rayon dyestuffs.  The impregnated fabric may be allowed to lie at room temperature for a period before finally washing and drying.  The amount of acid added is preferably ,2--5 per cent of the weight of the impregnating liquor.  In examples: (1) a viscose fabric is impregnated with a formaldehyde solution containing o-amino phenol p-sulphonic acid, dried in hot air at 80 DEG  C., washed in slightly alkaline solution and dried; the fabric is crease-resisting; (2) a viscose fabric is impregnated with a solution of formaldehyde, naphthionic acid and Lissamine Fast Yellow 2G, dried at 70 DEG  C. and finished as in example 1; (3) a viscose cr<\>zepe fabric is impregnated with a solution of formaldehyde and benzene sulphonic acid, dried under tension at 60 DEG  C., washed and dried; the fabric is crease and shrink resistant; (4) a viscose fabric is printed with a zinc oxide paste, dried, and impregnated with a solution of formaldehyde, phenol 2-sulphonic acid and Acid Scarlet 4R, dried at 70 DEG  C., washed and dried; a white pattern on a red ground is produced.

Abstract: 741,679. Carbonizing processes. COAL INDUSTRY (PATENTS), Ltd. March 30, 1954 [March 30, 1953; March 30, 1953], Nos. 8755/53 and 8756/53. Class 55 (1). Coarse or briquetted coal or other carbonaceous substance is heated in a stationary retort through which is passed a stream of heated granular material, e.g. sand or coke breeze, at a velocity relative to that of the coal which may be stationary, the material flowing around the coal as a separate and distinct stream. A sand heater 1 is heated initially by a gas burner 6 and by the combustion of fine coal or coke breeze introduced through a pipe 42 by a compressed air supply which also maintains the sand in fluidized condition. The hot sand overflows through a pipe 9 and controlled orifice 10 into a carbonizer 12 to which coal briquettes are fed through a rotary valve 13. The sand is separated by a screen 21 from the carbonized briquettes which pass through a water seal 22 to a scraper conveyer 23. The sand is returned pneumatically to the heater by hot gases from a burner 27 through a line 26 an electrically operated valve 47A maintaining a minimum level of sand in an inlet pipe 47 to prevent the escape of the transport gases. Removal of distillation gases from the retort through a line 30 is assisted by steam injected through an inlet 16 and tar &c. is condensed by a water jet 17.. In a modification hot sand and combustion products enter the carbonizer from below and flow in countercurrent to the briquettes. In discontinous operation briquettes are moved batch wise; a series of carbonizers may be used with the supply of briquettes and sand in countercurrent.

Title: An electrical arrangement for the detection of deformation, suitable for use on vehicles
IPC: B64D45/00
Filed: 1949-03-31
Abstract: 666,169. Impact-operated switches; inertia switches.. TECALEMIT SOC. ANON. March 31, 1949. [May 26, 1948; July 21, 1948] Nos. 8818/49 and 8819/49. Class 38 (v). A device for detecting deformation of a member on which it is mounted such as the surface of an aircraft, whereby fire-extinguishing apparatus is operated in the event of a crash, comprises a bare conductor wire 3" supported by spaced insulator 5 in a tubular conductor 1<SP>11</SP>. The latter is earthed and the wire 3<SP>11</SP> connected to the positive side of a battery 4 so that on contact being made between 1<SP>11</SP>, 3<SP>11</SP> due to deformation of the tube 1<SP>11</SP> a circuit is completed through the detonator 13 of the fire-extinguisher 11. To increase the sensitivity of the tube 1<SP>11</SP> the insulators 5 are spaced further apart, and where the tube is curved for securing to a correspondingly-shaped surface, the insulators are closer together, Fig. 2 (not shown). The system may include an inertia-operated device as disclosed in the French Specification 963,129, comprising a spherical metal core 7 having a number of points 10, 10<SP>1</SP> normally spaced from an earthed shell 6 by rubber elements 9. In the event of a shock in anv direction the circuit to the detonator 13 is completed through the shell 6 and core 7. Fig. 4 (not shown), illustrates an aircraft-equipped with the system. To enable contact to occur between the tube 1<SP>11</SP> and wire 3<SP>11</SP> for smaller degrees of bending of the tube, the wire 3<SP>11</SP> is weakened at selected points such that its greater length remains straight and bears tangentially against the tube when the latter deforms. This is achieved, Fig. 6, by surrounding the part of the wire 21<SP>1</SP> between the insulator 23 by a conducting tube 21. Alternatively, the wire 21<SP>1</SP> could itself be narrowed in the region of the insulators or in a section mid-way between them, Figs. 11, 12 (not shown). Other modifications, Figs. 8-10, 13-16 (not shown) consist in employing tempered steel wire, annealed at the insulators or between them, and in coiling the wire at these places.

Abstract: A stabilized sulphur trioxide composition comprises normally liquid sulphur trioxide (i.e. that form melting at about 17 DEG  C.) and one or more phosphorus compounds soluble in the sulphur trioxide and containing the group - P(Cl2)=N -, e.g. phosphonitrilic chloride polymers of formula (PNCl2)x, where x is an integer greater than 2, preferably 3 or 4, in an amount sufficient substantially to prevent polymerization of the normally liquid sulphur trioxide to higher melting forms at temperatures below 27 DEG  C.  The phosphorus compounds of another preferred class contain the structure P(Cl3)=N -.  The invention is particularly applicable to the stabilization of liquid SO3 containing 0.01 to 0.1% of sulphuric acid by weight of the total composition, but may also be used for stabilizing anhydrous liquid SO3. The phosphorus compound is generally added to the liquid SO3 in amount 0.05 to 1.0%, preferably 0.1 to 0.25%, by weight of the sulphur trioxide.  The composition may also contain an inert organic solvent for the phosphonitrilic chloride polymer.  Pressure treatment may be used at 50 DEG  to 100 DEG  C. for 2 to 10 hours to enhance the stability of the liquid SO3. The stabilizer may be added directly to the liquid SO3 and dissolved by agitation, or SO3 vapour may be condensed in a closed vessel already containing the stabilizer.

Title: Production of foamed polylactams
IPC: C08J9/14
Filed: 1964-03-04
Abstract: The density of a foamed polylactam is controlled by initiating the polymerization reaction of a lactam containing at least 6 carbon atoms in the lactam ring in the presence of a catalyst, a promoter and a blowing agent at a first temperature and allowing the reaction to proceed exothermically to completion at a second temperature, the blowing agent being selected such that it will remain passive at said first temperature, but will be activated at a predetermined third temperature which is above the first temperature but below the second temperature. The polymerization reaction may be effected in a mould cavity, the wall of which may be adjusted to a temperature which is different from the third temperature.  When the temperature of the wall is below the third temperature a smooth, impervious surface will be produced on the foam product and when the temperature of the wall is above the third temperature a highly pervious surface will be produced on the foam product.  The temperature of the mould cavity wall may be at a temperature at or above the first temperature. Suitable lactams are e -caprolactam, enantholactam, caprylolactam, decanolactam, undecanolactam, dodecanolactam, pentadecanolactam, hexadecanolactam, methylcyclohexanone isoximes and cyclic hexamethylene adipamide.  The catalyst may be an alkali or alkaline earth metal or compounds thereof, organometallic derivatives of such metals and in addition of aluminium.

Abstract: 1277187 Etherified styrene polymers FORD MOTOR CO 25 Feb 1970 [25 Feb 1969] 9163/70 Heading C3P Cross-linkable polymers have, attached to their backbone, thermally labile pendant phenylene quinol ether groups which groups are preferably of the formula The polymer is preferably a styrene polymer, the phenylene quinol ether groups being derived from the pendant phenyl groups of the styrene polymer which are substituted by quinoxy groups, as in the formula. The groups may be introduced by reacting, for example a phenyl ether of a quinol, with a polymer containing pendant hydroxy phenyl groups. In the examples styrene and 3-acetoxy styrene are copolymerized in bulk using azobis-isobutyronitrile, the acetoxy groups are then hydrolysed to produce hydroxyl groups using NaOH in a dioxane and water mixture, and then the hydroxy groups were reacted with 2,4,6-tri-t.-butyl quinoxy radicals in benzene, to give a styrene polymer whose phenyl groups are substituted by quinol ether groups. The polymer cross-links thermally due to the dissociation of the ether groups to produce phenoxy radical pendant groups.
