Title: Improvements in or relating to a process for the production of siliceous refractory articles
IPC: C04B35/14
Filed: 1937-04-22
Abstract: Refractory articles are made by forming a mouldable mix of siliceous material with small proportions of a barium compound and a compound of iron or metallic iron, moulding the mix and firing under reducing conditions, finally replacing the reducing conditions by oxidizing conditions either while continuing the firing or while slowly cooling.  The resulting refractory is stated to consist essentially of tridymite bound by a barium-iron-silicate glass.  Siliceous materials specified are quartz, ganister and siliceous fireclays. The iron compound may be for example the carbonate, oxides or silicates and may be present as such or contained in the siliceous material as an impurity or combined with the barium compound as barium ferrite or as barium iron silicate or gillespite glass prepared by heating 368 parts of barium oxide, 69 parts of ferric oxide and 517 parts of silica; the content of iron or iron compound in the mix is usually 1/8 -4 per cent expressed as iron oxide.  Other barium compounds specified are the aluminate, carbonate, chloride, hydroxide, oxide and peroxide; the amount of barium compound in the mix is usually 2 per cent expressed as barium oxide.  A temporary binder, e.g. cellulose sulphite waste liquor concentrate, dextrin or starches, and/or carbon, preferably lampblack, may be incorporated in the mix; organic binders and carbon insure the presence of the reducing conditions during firing.

Abstract: 381,113. Plant. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES., (formerly ZAHNRADFABRIK AKT.-GES.), Friedrichshafen, Lake Constance, Germany. April 22, 1932, No. 11552. Convention date, April 25, 1931. [Class 7 (ii).] An aircraft or other propeller shaft driven from two or more motors has means for disconnecting and connecting any motor at will, a delay-action device being incorporated whereby the change-over is completed automatically when there is no load transmitted between the motor and the propeller shaft. Fig. 1 shows a propeller shaft S driven through bevel gear from two motor shafts M1, M2 through two dogclutches 4, 5. The ends of the teeth on the clutch members 4, 5 are bevelled in such a direction that engagement is prevented until the motor shaft speed has become equal to the speed of the member 5. Each member 4 is mounted on a shaft 4<1> capable of sliding through a member 9 driven from the motor shaft through elastic discs 11, teeth 10 preventing overload of the discs by limiting the amount of relative rotation. The shaft 4<1> is connected by a bearing 14 to a member 15 having a quick-threaded screw 17 engaged by a nut 18 provided with an actuating lever 19. The upper end of this lever is engaged by a slotted member containing a spring which becomes compressed if the nut is unable to move the member 15. A toothed disc 12 on the other end of the shaft 41 occupies the position shown to the left of Fig. 1 when the clutch 4, 5 is engaged and owing to relative displacement of the motor shaft and part 9 under torque is unable to pass through a toothed ring 13 on the motor shaft. As soon as the torque becomes zero the member 12 can pass through the ring 13 and the clutch member 4, 5 can be disengaged.
