    摘要: Method for producing metal oxide nanoparticles. The method includes generating an aerosol of solid metallic microparticles, generating plasma with a plasma hot zone at a temperature sufficiently high to vaporize the microparticles into metal vapor, and directing the aerosol into the hot zone of the plasma. The microparticles vaporize in the hot zone into metal vapor. The metal vapor is directed away from the hot zone and into the cooler plasma afterglow where it oxidizes, cools and condenses to form solid metal oxide nanoparticles.

    摘要: Method for producing metallic particles. The method converts metallic nanoparticles into larger, spherical metallic particles. An aerosol of solid metallic nanoparticles and a non-oxidizing plasma having a portion sufficiently hot to melt the nanoparticles are generated. The aerosol is directed into the plasma where the metallic nanoparticles melt, collide, join, and spheroidize. The molten spherical metallic particles are directed away from the plasma and enter the afterglow where they cool and solidify.

    摘要: Spherical and polyhedral particles of boron nitride and method of preparing them. Spherical and polyhedral particles of boron nitride are produced from precursor particles of hexagonal phase boron nitride suspended in an aerosol gas. The aerosol is directed to a microwave plasma torch. The torch generates plasma at atmospheric pressure that includes nitrogen atoms. The presence of nitrogen atoms is critical in allowing boron nitride to melt at atmospheric pressure while avoiding or at least minimizing decomposition. The plasma includes a plasma hot zone, which is a portion of the plasma that has a temperature sufficiently high to melt hexagonal phase boron nitride. In the hot zone, the precursor particles melt to form molten particles that acquire spherical and polyhedral shapes. These molten particles exit the hot zone, cool, and solidify to form solid particles of boron nitride with spherical and polyhedral shapes. The molten particles can also collide and join to form larger molten particles that lead to larger spherical and polyhedral particles.

    摘要: A method for generating spherical and irregularly shaped dense particles of ceramic oxides having a controlled particle size and particle size distribution. An aerosol containing precursor particles of oxide ceramics is directed into a plasma. As the particles flow through the hot zone of the plasma, they melt, collide, and join to form larger particles. If these larger particles remain in the hot zone, they continue melting and acquire a spherical shape that is retained after they exit the hot zone, cool down, and solidify. If they exit the hot zone before melting completely, their irregular shape persists and agglomerates are produced. The size and size distribution of the dense product particles can be controlled by adjusting several parameters, the most important in the case of powder precursors appears to be the density of powder in the aerosol stream that enters the plasma hot zone. This suggests that particle collision rate is responsible for determining ultimate size of the resulting sphere or agglomerate. Other parameters, particularly the gas flow rates and the microwave power, are also adjusted to control the particle size distribution.

    摘要翻译: 一种用于产生具有受控粒度和粒度分布的陶瓷氧化物的球形和不规则形状致密颗粒的方法。 将含有氧化物陶瓷的前体颗粒的气溶胶引入等离子体。 当颗粒流过等离子体的热区时,它们熔化,碰撞和连接形成较大的颗粒。 如果这些较大的颗粒保留在热区中,则它们继续熔化并获得在它们离开热区后保持的球形,冷却并固化。 如果它们在完全熔化之前离开热区,则它们的不规则形状仍然存在并且产生附聚物。 致密产品颗粒的尺寸和尺寸分布可以通过调节几个参数来控制,在粉末前体的情况下最重要的是在进入等离子体热区的气溶胶流中的粉末密度。 这表明颗粒碰撞速率负责确定所得球体或附聚物的最终尺寸。 还调整其他参数,特别是气体流速和微波功率,以控制粒度分布。

    摘要: The invention provides a crank assembly for a chain driven mechanism such as a bicycle. The crank assembly has at one end of a crank arm, a journal adapted for engagement with an axle. The axle has at its other end a connection. The one end of the crank arm has mounted thereon a housing via a unidirectional variable clutch, the housing having an extension to which, in use, an activation means such as a brake cable or cables is/are attached. The arrangement is such that during normal forward rotation the crank arm moves normally and the housing is stationary relative thereto, while during back or reverse movement of the crank arm the housing moves to activate the brake cable or cable means.
