This is an inquiry message about Proposal in the 108th China Canton Fair. (这是一条买家关于"Proposal"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) Proposal Dear Sir, I have made an invention (see publication Int J Mech Mater Des DOI 10.1007/s10999-009-9098-2). The device described in this publication has a number of unusual effects. On the basis of these effects I managed to develop some devices which are not described yet in the technical literature. One of such devices is a gravity roller conveyor with unusual properties. The main property is that direction of a vector of speed of subjects which move on such conveyor depends on their specific pressure upon the conveyor surface. This property gives an opportunity to assort automatically these subjects without use of any measuring devices. From my point of view such conveyors can assort subjects on the basis of following criteria: ? flat subjects having an identical thickness will be assorted according to their relative density; ? subjects of identical density will be assorted according to their thickness; ? spherical subjects from an identical material will be assorted according to their external diameter; ? three-dimensional subjects of the identical form will be sorted according to their weight. The same property gives an opportunity to design the conveyor so that subjects on this conveyor during displacement will be automatically moved to the conveyor center line. Subjects having sizes that exceeding width of the conveyor will not fall out from such conveyor. One more important property of such conveyor is that it can be made as a continuous compliant belt similar to a flexible rug. Such rug can be even bent to be a tube. Last circumstance allows making from such rugs analogues of rolling bearings, analogues of screws and nuts of rolling. Cost of the offered conveyor can be cheaper than cost of the usual gravity roller conveyor because to make it technologically is easier. In Israel where I live now I do not manage to find an organization which seriously would become interested in this my invention. I have not patented this new invention and did not publish any information about it. If you will be interested in the gravity roller conveyor described by me, I am ready to arrive to you, to tell about other paradoxical versions of such conveyor, and to discuss prospects of manufacturing of such conveyor. Moreover, I am ready within no more than a week to make an elementary demonstrative model of such conveyor.
