Title: Process for preparing Titanium Halides
IPC: C01G23/02
Filed: 1968-01-10
Abstract: 1,193,371. Titanium halides. MIZUSAWA KAGAKU KOGYO K.K. 10 Jan., 1968 [10 Jan., 1967], No. 1491/68. Heading C1A. Titanium tetrahalides are prepared by forming mixture of a hydrogel or a xerogel of a titanium salt of a phosphorus oxyacid with at least one halide of an alkaline earth metal, heating the mixture in the solid phase under non- oxidizing conditions at a temperature between 300 C. and the highest temperature at which the mixture can remain in the solid state for a period of time sufficient to form the titanium halide, and thereafter recovering the halide produced. The said phosphorus oxyacid may be orthophosphoric, metaphosphoric, pyrophosphoric, hexametaphosphoric, tripolyphosphoric, phosphorous, or hypophosphorous acid, and the alkaline earth metal halide is preferably the chloride, bromide, or iodide, of Mg, Ca, Ba, or Sr, and may be a fluoride, but these tend to cause corrosion of the apparatus. Sufficient halide is used to provide 4 atoms of halogen per atom of Ti, and the halide and gel may be ground together as a paste using water, or the mixture formed by mixing a hydrosol of the Ti compound with the halide, in each case the resulting mixture being dried at a temperature not exceeding 400 C. The mixture is then heated in an atmosphere of argon, nitrogen, carbon dioxide, hydrogen, halogen, methane or a vacuum, and the product titanium halide is collected by cooling to a temperature between - 50 C. and room temperature. The titanium salt gel may be prepared as described in Specification 1,161,141.

Title: Improvements in or relating to the propulsion of air-craft
IPC: B64C23/00
Filed: 1920-01-16
Abstract: 160,041. Lupton, A. Jan. 16, 1920. Propelling.-The propeller is mounted in the mouth of a straight longitudinally-disposed conduit, and the air from the propeller can be expelled from the conduit either horizontally at the rear or downwardly through an opening in the floor of the conduit. In the construction shown in sectional plan in Fig. 1, the air from the propeller C normally passes through the open louvers F to the rear J of the conduit A, but the louvers F can be closed and the louvers E opened to direct a current of air downwardly and so reduce the impact with the ground on landing. The louvers E may be replaced by a sliding grid co-operating with a fixed grid in the floor of the conduit on the hit-and-mies principle. In another construction, Fig. 5, a baffle M can be placed in the position shown to close the throughway to the rear of the conduit and open the aperture at A', or turned down to close the aperture and open the throughway. As the baffle is turned down, the air deflectors 0, R are turned up to lie along or in line with the wall of the conduit, the deflector 0 closing a gap formed in the baffle M to clear the cockpit D. Additional wheels, which are lowered with the deflectors when the baffle is raised, may be provided, as at Q, to protect the deflectors on landing. Cars and cabins.-The upper part of the wall of the air conduit A may be cut away at D to provide the cockpit.
