Title: Improvements in shirt collars and other articles of washable and starchable wearing apparel
IPC: A41B3/00
Filed: 1930-05-05
Abstract: 354,260. Multiple fabrics for shirt collars &c. KULMBACHER SPINNEREI AKT.-GES., Kulmbach, Bavaria, Germany. May 5, 1930, No. 13796. Convention date, Nov. 12, 1929. [Class 142 (iv).] A shirt collar or other article of washable wearing apparel capable of being worn starched or unstarched is made of multiple fabric having at least two woven plies and at least three layers of weft with the face layer joined to the other layer or layers by the warp threads of the layers as distinct from separate binding warps. In some constructions, warps 41, Fig. 8, interweave with the wefts 44. 45 of the outer layers and pass through an intermediate layer comprising warps 42 and wefts 43. This layer may have fewer wefts than the other layers, so that starch receiving cavities are formed. In other constructions as in Fig. 4, warp threads of the intermediate layer interweave with the outer layers, or as in Fig. 6 warps of a lower layer interweave at times with the wefts 29 of a top layer. Specification 266,284, [Class 142 (iv), Woven fabrics &c.], is referred to.
Patent GB-670355-A (GB)
Title: Improvements in or relating to the manufacture of melamine
Filed: 1949-05-24
Abstract: Melamine is made by heating ammonia and carbon dioxide at elevated temperatures and superatmospheric pressure in a closed high-pressure system comprising at least one hot zone at above 275 DEG  C. and at least one zone which is cooler than the hot zone and controlling the pressure within the system by adjusting the pressure of the cooler zone.  The temperature of the hot zone is preferably above 350 DEG C., ranges specified being 350 DEG  to 500 DEG  C., preferably 375 DEG  to 450 DEG  C.  At these temperatures pressures of 2000-5000 p.s.i. are automatically generated and may be controlled by changes in temperature of the cooler zone or zones for which a temperature range of 120-165 DEG  C. is given. 3000-4000 p.s.i. is a preferred pressure range.  The molar ratio of ammonia to carbon dioxide may be 0.77 to 1 but is preferably above at least 2 to 1, e.g. about 5 or 20 to 1, such high ratios being preferred.  Inert gases or liquids may be present, e.g. hydrogen, nitrogen, air or carbon monoxide.  The removal of oxygen is preferred.  In an example, the mol. ratio of ammonia to carbon monoxide is about 5 : 1, hot zone temperature 400 DEG  C. approx., cold zone temperature 120-165 DEG  C., varying to give a pressure of about 3500 p.s.i. and the reaction time is about 30 minutes.  The apparatus consists of two autoclaves joined by high-pressure tubing.
Patent GB-495774-A (GB)
Title: Improvements in or relating to methods of manufacturing fluorescent materials for cathode-ray tubes
IPC: C09K11/58
Filed: 1937-05-18
Abstract: A fluorescent sulphide is prepared by heating the oxide or hydroxide of a metal, or a mixture of metallic oxides or hydroxides, with sulphur in an atmosphere of hydrogen or sulphuretted hydrogen to a temperature exceeding 400 DEG  C. in the presence of a heavy metal adapted to activate the sulphide.  The reaction time may be shortened by heating under increased pressure.  In examples, zinc sulphide activated with copper is prepared from a mixture of zinc hydroxide, sulphur and copper nitrate; and zinc-cadmium-sulphide activated with silver is prepared from a mixture of zinc hydroxide, cadmium hydroxide, sulphur, and silver nitrate.  Reference is made to similar known methods of preparing unactivated sulphides; and to known methods of preparing activated sulphides in which the sulphide is precipitated from a metallic salt solution by sulphuretted hydrogen or ammonium sulphide and is then ignited in the presence of a heavy metal activator, or is formed by reduction of a sulphate or oxide in an atmosphere of nitrogen and carbon bisulphide in the presence of a heavy metal activator.

Title: Catalytic process for the manufacture of hydrogen
IPC: C01B3/16
Filed: 1927-05-23
Abstract: 271,523. Grenier, R. J. A. May 22, 1926, [Convention date]. Methyl alcohol.-The reaction between carbon monoxide and steam for the production of hydrogen is effected with the use as catalyst of carbon in the porous state; the preferred catalyst is wood charcoal. For example, the production of hydrogen may be effected by passing carbon monoxide, or gases, such as water gas, poor gas, or coke oven gas, containing carbon monoxide, admixed with steam through a gas-heated iron tube filled with wood charcoal. The reaction may be effected under pressure and at a temperature of 350‹ C. The Specification as open to inspection under Sect. 91 (3) (a) states that other reactions in which carbon monoxide takes part, such as the production of methyl alcohol from carbon monoxide and hydrogen are effected in a similar manner. This subject-matter does not appear in the Specification as accepted.

Abstract: 616,342. Toothed gearing; screw-and-nut gearing. CENTRE D'ETUDES TECHNIQUES ET D'INVENTIONS. June 6, 1945, No. 14265. Convention date, Sept. 25, 1941. [Classes 80 (i) and 80 (iii)] In a mechanism for eliminating backlash, especially in gear-cutting machinery, the member taking up the slack is similar to and driven by the driving member, and is connected thereto through a vernier adjustment so that it is always in contact with the driven member. A worm-wheel 11 is driven by a worm 10 which has a bevel 13 secured to its shaft. A second worm 15 also meshing with the wheel 11 has a freely rotatable sleeve 17 on the end of its shaft. A bevel gear 14 integral with the sleeve meshes with the bevel 13. The end of sleeve 17 is formed as a toothed ring, a second toothed ring 18 being keyed to the end of the shaft of the worm 15, between these two'rings is fitted a double toothed ring 16. The numbers of teeth in rings 17, 18 being slightly different, a vernier is formed and a worm 15 can be driven in the same direction as worm 10, but its teeth will bear constantly against the opposite flanks of the teeth of the worm-wheel 11 and so eliminate backlash. In a modification for use with screw-and-nut mechanism, a second screw, driven by gearing through a vernier, is provided on the opposite side of the main member moved, backlash being eliminated by similar opposite pressures between the screw-threads.

Abstract: 108,587. Birch, C., and Price, F. Oct. 13, 1916. Turning.-A vertical turret for lathes is angularly adjustable as at c on its base slide c and is held on its seating in a counterbored recess j by a clamping rod q prevented from turning by a flat and screw s. On unclamping, a spring m advances the turret to disengage the locating pin from the index hole p. When it is desired to remove the turret, to exchange it, for example, for the circular turret shown in Fig. 7, the short pin o is replaced by a pin long enough to engage a hole n. On unclamping, the rod can then be pushed endways to dislodge the C-washer w from its recess in the turret so that it may be removed from the neck u, The long pin is next withdrawn and the turret removed bodily. The tool holes are arranged as shown in Figs. 2 and 4 so that long tools may be used without interference, the tool in operation being that on the top edge of the turret.

Abstract: 239,926. Dowsett, H. M., and Tilley, H. B. June 17, 1924. Wire resistances, embedded and cored.-A resistance is formed by winding an enamelled wire 2, Fig. 3, which is also covered with an absorbent material such as silk or cotton upon a silica, porcelain, resistant-glass or other refractory core 1, impregnating the absorbent with enamel and stoving and finally covering the resistance so formed with another coating of enamel 6 and stoving at a temperature above the normal working temperature. A piece of pliable copper braid 3 is lashed to the core 1 by bare copper wire 4 and forms an end connector, the resistance wire 2 being entwined with the wire 4 after being bared for a length of about two feet. The braid is then turned back and soldered as shown at 5 with high melting solder. A clip 7, Fig. 2, is secured to each end of the unit bv means of a clamping screw 8 to which the braid is attached. An alloy having a negligible temperature coefficient is preferably employed for the resistance, and several coatings of enamel may be applied to the unit; the final stoving however, to avoid cracking the enamel should be conducted at about 230‹-270‹ C. The refractory core may be rendered impervious to moisture by glazing.
