摘要： A process for preparing 2-methylbenzoxazole by cyclizing acetamidophenol with the simultaneous elimination of the water of reaction. The process involves the drying and melting of the acetamidophenol, the cyclization of acetamidophenol to 2-methylbenzoxazole, and the removal of the water of reaction and the 2-methylbenzoxazole from the reaction mixture after the cyclization step by distillation. All the steps are carried out in a dryer.

摘要： The upper surface of a guide-plate (11) guides the paper webs. A cover (16) made of solder or welding material, preferably refined steel plate, sealed along the edges is spaced apart from, and joined to, the guide plate. The cover has holes (17) in the area of the nozzles (15) which are sealed from the coolant conveyed to the reverse side of the guide plate. The space (22) between the cover and reverse side of the guide plate contains at least one inlet and outlet for the coolant. Air receivers (24) on the plates' reverse side convey the air to the nozzles and are sealed near the holes in the reverse side. The guide plate consists of at least two sandwich-type metal plates (12,14) joined by an intermediate layer (13).

摘要： 461,170. Helicopters. KONIG, J., and KADLEC, J. June 29, 1936, No. 17967. Convention date, June 29, 1935. [Class 4] A helicopter, Fig. 1, has oppositely rotated superposed helical screws 1, 2, respectively secured to shafts 3, 5, which together with driving engines 7 and fuel tanks 16, are mounted in a casing 13 closed by a cover 14 and connected to a nacelle 12 bv trunnion bearings 15, Fig. 3, and adjustable relative thereto in the fore and aft plane. The adjusting means comprise a toothed segment 19 secured to casing 13 with which meshes a pilotoperated worm 20. The helical screws each consist of curved rods or tubes fitted into hubs keyed to the shafts and successively angularly displaced in such manner that when fabric is secured to the rib elements, helical surfaces are produced. A thrust bearing 27 is interposed between the two screws and shaft 3 carries a retaining nut 28. Shaft 3 is fitted with a pinion 4, Fig. 4, at its lower end and shaft 5 with an internally toothed gear ring 6. Gears 4 and 6 are engaged by pinions 8, 9 secured to driving shafts of motors 7.
