Abstract: 1,183,092. Coated steel sheet. YAWATA IRON & STEEL CO. Ltd. 14 March, 1967 [18 March, 1966], No. 11813/67. Heading B2K. [Also in Division C7] In a process for annealing an aluminium containing silicon steel sheet (e.g, containing 0.01-0.09% soluble Al) the annealing separator comprises a coating of a Mg compound and one or more compounds of Mn, Cu, Cr or Zn which has been applied as a solution or suspension thereof. During the annealing in a high temperature reducing atmosphere, the above compounds and Al 2 O 3  in the surface of the steel sheet form a glassy electrically insulating film. The ratio of Mg compound to other compound (calculated as the monoxide) is preferably 98:2 to 20:80. The coating may be applied by roller, spraying or dipping of a mixed solution of the required compounds or the Mn compound may be applied as a first layer and the Mg as a second layer. Alternatively one of the layers in a two layer process may be applied by electrolysis. The coated sheet may be given a further coating by applying, drying and baking a coating using a solution prepared by adding at least one of water glass, MgO, CaO, ZnO and silicic anhydride, to a solution containing H 3 PO 4  5-40 wt. %. Cr<SP>6+</SP> compound 1-10 wt. % #boric acid or a borate #less than 8 wt. % alternatively a solution of 1-6 wt. % zinc dichromate with 1-4% glycerine and 2-5% boric acid may be used. Where the sheet does not need to be stress-relief annealed an organic, or mixed organic/inorganic, film may be applied to the coated sheet.

Filed: 1929-04-17
Abstract: 310,842. Aceta Ges. May 1, 1928, [Convention date]. Cellulose esters and ethers, processes for making filaments from.-In the manufacture of artificial threads from cellulose acetate and other esters and cellulose ethers by the wet spinning process particularly the stretching-spinning process there is added to the precipitating bath containing a salt having a swelling action a colloid substance such as molasses, sulphite cellulose lye, a tanning agent, soluble starch, albumen, or a soluble synthetic resin. Sulphite cellulose lye and degraded keratin solution are particularly suitable. A swelling agent soluble in water may be added to the spinning solution when the proportion of swelling agent required in the precipitating bath is reduced. The coagulating action of the precipitating bath may be modified by addition of a salt with no swelling action and of a non volatile or slowly volatile substance such as a chlohhydrin, a. monacetin, or a phenol. In examples cellulose acetate in acetone is spun into a bath containing ammonium sulphocyanide and sulphite cellulose lye, molasses residue, or a degraded keratin solution; cellulose acetate in acetone containing aqueous ammonium sulphocyanide is spun into a bath containing ammonium sulphocyanide and degraded keratin solution.

Filed: 1917-08-29
Abstract: 166,171. Marks, E. C. R., (Kuppenheim, L. [Firm of]). Aug. 29,1917. Making metal fabrics.-In ring-fabric machines having the fabric supported on rotating spirals 16, automatic means are provided for giving the required movements to the spirals. A clutch member 7, feathered to slide on a shaft 8 which is capable of a small axial movement, is moved axially to engage one or other of the clutches 10 by bell-crank levers 6, 5, cam 4, ratchet gear 3 from the main shaft 104. This carries eccentrics 14 which oscillate toothed segments 11 in gear with pinions 9 loose on the shaft 8 but connected through oppositely-acting free-wheel clutches to the members 10. The shaft 8 is thus given an axial movement equal to one-half a ring diameter, then a number of intermittent rotations, and then similar movements in the reverse direction, and these movements are transmitted to the spirals 16 through gears 22, 21 and flanges 21a. The vertical positions of the spirals are interchanged by supports 17, which have bores for the spirals slit at the bottom to allow the fabric to depend therefrom. The supports are pivoted to standards 18 and oscillated slightly by a wedge 27, Fig. 1, on the lever 6 and link-work 25, 23, 24. Two springs 28 are brought into operation alternately, to lift the rings being made, so as to be taken up by the receiving spiral, by arms 33, 35 operated by link-work 34, 31, 30 from the lever 6. The ring fabric is received in a pan 38 suspended by a half-nut 36 from a screw on the shaft 8, so that it moves with the fabric.

Abstract: 348,850. Setting and indicating apparatus for engine valves and ignition gear. TRIGGS, W. W., 57, Lincoln's Inn Fields, London. -(Automatic Motor Control Corporation ; 113, East 138th Street, New York, U.S.A.) April 23, 1930, No. 12531. [Class 122 (iii).] A device for indicating faults in the working of internal-combustion engines comprises a housing adapted to be attached in an opening in the engine cylinder, an indicating device carried by the housing, and an actuating member for the indicating device adapted to be operated by a pressureinfluenced member and also by a member moved by the engine piston. A plug 14 through which passes a rod 17 with an overhanging end 18 is adapted to screw into the sparking-plug hole. The rod is pressed down by a spring 20 and is screwed at the top to receive a cap 22. In use, the plug is screwed into the cylinder to be tested and the cap adjusted so that the pin 19 does not contact with the plug when the piston is at the end of its stroke. This may be done by adjusting the cap above the index mark 24 corresponding to the make of engine on a flat on the rod 17. The cylinder 11 carrying the indicating device is now screwed over the plug. On cranking the engine until the cylinder is on the compression stroke, the gas in the engine cylinder passes through an opening 25 to the cylinder 11 and raises the piston 36 causing it to raise a spring-pressed rod 34 the rack portion of which operates a pointer pinion 28. The maximum pressure may be read on the outside graduation of the indicator. If this pressure falls rapidly, the valves are probably leaking; and if gradually, the piston rings are probably not tight. In either case, the gauge piston drops back until it contacts with the cap 22 in which position the top of the engine piston travel is indicated, on the inner scale. The engine piston is now allowed to descend for the power stroke and the pointer is watched. Two adjustable electric contacts 43, 46 are watched through a window 48 as the piston moves down, and the graduation reached when the spark passes is noted. This enables the timing to be checked. By drawing out the gap some idea may be obtained of the strength of the spark.
