Patent GB-357084-A (GB)
Title: Improvements in or relating to the manufacture of fabrics exhibiting crepe effects
Filed: 1930-05-07
Abstract: For the manufacture of fabrics exhibiting crape effects, fabrics containing highly twisted crape threads are treated with dehydrating agents or concentrated solutions of salts, and then with water or other aqueous medium.  Specified reagents for the initial treatment are ethyl or methyl alcohol, benzene (which removes water as an azeotropic mixture when the fabrics are boiled therewith), and concentrated solutions of the following salts, viz.:-halides of alkaline-earth metals, lithium, and zinc, sodium bisulphate, sodium dihydrogen phosphate, alkali acetates, methylamine hydrochloride; and according to the Provisional Specification, aniline hydrochloride and acid sulphate; the salt solution may be applied to the fabrics uniformly or locally.  The dehydrating agent or salt solution may be applied to the crape threads prior to weaving or twisting, instead of to the fabrics. After the treatment with the dehydrating agent or salt solution, the fabrics may be scoured in an aqueous bath, or water may be applied in restricted quantity, e.g. in the form of air laden with water vapour, or by spraying.  The crape threads may comprise two or more highly twisted threads, of the same or different direction of twist, doubled together; they may constitute the weft alone, wholly or in part, or the warp may also contain them; or threads of relatively low twist may be employed in the warp, the weft comprising crape threads having a left-hand twist and also crape threads having a right-hand twist.  The crape threads may consist of or contain organic derivatives of cellulose, a number of which are specified, or degummed silk, regenerated cellulose, or other natural or artificial materials.  The fabrics may consist of organic derivatives of cellulose, or they may contain other fibres such as regenerated cellulose, cotton, wool or silk.  The crape threads may be sized prior to twisting or weaving, and the treatments described above may be adapted to swell the sizing materials (cf Specification 348,589).  According to the examples, (1) a fabric having a warp of cellulose acetate yarn of low twist and a weft of highly twisted cellulose acetate yarn is padded with a concentrated solution of calcium chloride, allowed to stand, washed in warm water containing a sulphonated oil, and dried; sodium or potassium acetate may be used instead of calcium chloride; (2) a fabric of the kind referred to in example 1 is treated with warm ethyl alcohol, dried, and then treated with a mist or fine spray of water; (3) a fabric of the kind referred to in example 1 is treated locally, by spraying through stencils, with a saturated solution of calcium chloride, allowed to stand, and washed in warm water.  Specifications 351,999 and 352,000 also are referred to.

Patent GB-997347-A (GB)
Title: Variable-area nozzle for use in commingling two or more fluid streams
IPC: F01N3/22
Filed: 1962-04-12
Abstract: 997,347. Injectors treating I. C. engine exhaust gases. UNIVERSAL OIL PRODUCTS CO. April 12, 1962 [April 13, 1961], No. 14128/62. Headings F1B and F1E. [Also in Divisions B2 and B3] In a variable area nozzle, for use in commingling two or more fluid streams, which has a hollow open-ended frustrum having a fixed cross-sectional area portion at its end of greater perimeter, at least one resilient cantilevered flat wall portion 17, Fig. 1, rigidly attached to the fixed cross-sectional portion is free to deflect in a direction outwardly from the space surrounded by said frustrum. Exhaust gas from the engine passes through inlet conduit 11 and nozzle 15 to discharge as a high velocity jet from opening 20. Air is drawn through one or more conduits or an annular slot 12 and mixes with the exhaust gas in diffuser 14 which communicates with a catalytic oxidation chamber (not shown). The exterior surface of nozzle 15 has secured thereto flat spring-metal vanes 17 e.g. of tempered spring steels such as manganese, chromium, nickel-chromium-molybdenum, the ends of the vanes 17 being free to deflect outwardly under internal pressure. At low rates of exhaust gas flow, vanes 17 are closed to form opening 20 to its minimum cross-section and optimum entrainment of air. With increase of exhaust gas flow vanes 17 are deflected outwardly to increase the area of opening 20 thus entraining less air. The vanes 17 may be incorporated into a pyramidal frustrum 32, Fig. 7 secured in the nozzle by outwardly-directed tabs 35. In modifications one, two, three or four walls of a nozzle are formed by resilient cantilevered deflection members, the remaining wall portions remaining rigid. In further modifications the vanes are formed as bimetallic temperature-responsive bending members, e.g. iron/invar, arranged with the material having the higher thermal expansion coefficient on the inside so that with higher rate of gas flow and temperature, the vanes are deflected outwardly. In another modification the vanes are formed as a layer of Teflon (R.T.M.) or fibreglass between inner and outer layers of the same on different metals. The nozzle may be formed as a regular or irregular pyromidal frustrum or partially conical and partially flat with three or more sides.

Abstract: The invention comprises 3-sulphanilamido-6-hydroxy-pyridazine and 3-benzenesulphonamido-6-hydroxy-pyridazines bearing in the p-position, as a substituent convertible into an amino group, an acylamino, nitro or azo group, and salts of these compounds such as the alkali or alkaline earth metal or magnesium or aluminium salts. The compounds are prepared by treating a compound of the formula <FORM:0878388/IV (b)/1> in which X is an amino group or, as a group convertible to amino by reduction or hydrolysis, an acylamino, nitro or azo group and Y is an esterified or etherified hydroxyl or mercapto group or a halogen atom or mercapto group, or when X is a substituent convertible to an amino group, Y may be a free hydroxyl group, to convert X and/or Y into a free amino or free hydroxyl group respectively.  Suitably X may be an acetylamino, carbethoxyamino or dichlorophosphorylamino group which is converted to amino by hydrolysis.  When Y is a halogen atom it is converted to hydroxyl by alkaline hydrolysis; a substituted hydroxyl or free or substituted mercapto group is also converted by hydrolysis.  The preferred process is the alkaline hydrolysis of 3-sulphanilamido-6-chloro-pyridazine.ALSO:Therapeutic preparations for treatment inter alia of intestinal infections in humans and animals comprise 3-sulphanilamido-6-hydroxypyridazine or a salt thereof in admixture or conjunction with a carrier suitable for enteral, parenteral or local administration.  The preparations suitably take the form of tablets, dragees, powders, salves, creams, suppositories, solutions, suspensions or emulsions, preferably containing 1 to 90% of the sulphonamide e.g. 10 to 85% in oral preparations and 10 to 35% in preparations for topical use.

Title: Toothed sawing chain
IPC: B27B33/14
Filed: 1956-05-11
Abstract: 812,385. Sawing; mortising. McCULLOCH MOTORS CORPORATION. May 11, 1956, [May 19, 1955], No. 14688/56. Class 145. A saw chain has cutter units A and B each comprising a leading cutter 13 and a following cutter 27, the cutter 27 being of opposite hand to the cutter 13 and closely following it so that one side 25 of the ribbon 26 removed from the bottom of the kerf 18 is cut and lifted by the leading cutter and then the ribbon is completely severed by the following cutter. The side links 12b and 12d opposite to the cutter links 12a and 12c carry depth gauges 23 and 30, the forward gauge 23 being above the cutting edge 16 of the leading cutter 13 to determine its depth of cut and the rear gauge 30 being at the same level as the cutting edge of the following cutter and being cranked to form a toe 31 which passes under the side 25 of the ribbon 26 partly severed by the leading cutter. The bottom of the gauge 30 slopes upwardly and forwardly and by filling the back face 35 it can be shortened to correspond with reduction of the cutters after they have been sharpened. When cutting hard woods, the depth of cut used is small and the volume of the ribbon cut is not great but, for softer woods, additional links 11s, 12s without cutters are fitted between the cutting units A and B to provide additional space 35<SP>1</SP> in which the ribbon can be accommodated. The ribbon cut by a unit A tends to turn on its side and as it is pushed forward to the end of the kerf by the depth gauge 23b of the unit B it folds concertina fashion in the space 35<SP>1</SP>. To prevent the chain from sagging between the cutter units, a runner 36, similar to the gauge 30 but shorter, is provided on the rear end of an additional link 12s. When the saw chain is extended round the rounded end of a saw bar and used to cut slots in a log, the runners 36 rotate round the chain rivets 10 to project a greater distance from the line of chain links and engage the bottom of the slot being formed, thereby preventing excess force being applied to the cutters. The leading cutters of the units A of a chain are arranged to be of opposite hand to those of the units B, resulting in a balanced action which prevents lateral drift.
