Abstract: A handle assembly for an infant carrier is provided. The handle assembly allows the handle to be oriented in one of a plurality of positions, such as a stroller position, and infant carrier position and a car seat position. The handle assembly may include a locking mechanism allowing a handle extension to be extended only when the handle rotated to the stroller position. The handle assembly may also include a blocking mechanism that prevents the handle from rotating from the stroller position if the handle is extended.

Abstract: A thermoplastic composite material has an inner layer material and at least one layer of outer layer material. The inner layer material is a core layer that contains fiber bundles, a first thermoplastic resin and a first auxiliary agent; and the at least one layer of outer layer material wraps the core layer and is a resin layer comprising a second thermoplastic resin and an optional second auxiliary agent. The fiber bundles extend continuously from one end of the core layer to the opposite end thereof. The inner layer-outer layer composite structure, can effectively improves the processing performance of the thermoplastic composite material and the lubricity between fibers and resin matrixes during injection molding, and improves the fluidity of the fibers in a resin matrix melt.

Abstract: Methods and processes for preparation and production of deuterated ?-diphenylurea are disclosed. Especially, a kind of deuterated ?-diphenylurea compounds which can inhibit phosphokinase and the preparation method of N-(4-chloro-3-(trifluoromethyl)phenyl)-N?-(4-(2-(N-d3-methylcarbamoyl)-4-pridinyloxy)phenyl)urea are disclosed. The said deuterated diphenylurea compounds can be used for treating or preventing tumors and relative diseases.

Abstract: Disclosed are an intermediate compound of N-(1,1,1-trideuterated methyl)phthalimide, and its use in the preparation of deuterated diphenylurea derivative.

Abstract: A fluoro-substituted deuterated diphenylurea compound, especially 4-(4-(3-(4-chloro-3-(trifluoromethyl)phenyl)ureido)-3-fluorophenoxy)-2-(N-(methyl-d3))picolinamide, preparing method and use for treating or preventing tumor and relative diseases thereof.

Abstract: A fluoro-substituted deuterated diphenylurea compound, especially 4-(4-(3-(4-chloro-3-(trifluoromethyl)phenyl)ureido)-3-fluorophenoxy)-2-(N-(methyl-d3))picolinamide, preparing method and use for treating or preventing tumor and relative diseases thereof.

Abstract: Preparation methods of methyl-d3-amine and salts thereof are provided, which contain the following steps: (i) nitromethane is subjected to react with deuterium oxide in the present of bases and phase-transfer catalysts to form nitromethane-d3, which is subsequently subjected to reduction in an inert solvent to form methyl-d3-amine, and optionally, methyl-d3-amine reacts subsequently with acids to form salts of methyl-d3-amine; or (ii) N-(1,1,1-trideuteriomethyl)phthalimide is subjected to react with acids to form salts of methyl-d3-amine. The present methods are easy, high efficient, and low cost.
