Abstract: A process for forming an image on a substrate, comprises depositing ink compositions of at least two colors onto the substrate to form the image, and fixing the image to the substrate, wherein the ink is deposited using an electrostatic printhead, which ejects chargeable marking particles dispersed in a carrier fluid by using an applied electric field to first concentrate and then eject the marking particles, and wherein all of the ink compositions are deposited onto the substrate before the image is fixed. An ink composition suitable for use in the invention comprises: 45-95% by weight of a carrier liquid; 6-40% by weight of insoluble chargeable marking particles; and 0.4-10% by weight of a soluble dispersant, characterized in that the ink does not contain an agent that can fix the marking particles to a substrate.

Abstract: The system for measuring wear in a grinding mill has at least one bolt passing through the shell and a wear plate. The bolt has an elongated oblong-shaped bolt head extending through the wear plate, flush with a surface of the wear plate. The bolt head is exposed to a same abrasion as the wear plate. The bolt has a groove there along and a plurality of wire loops embedded in that groove. Each wire loop extends to a distinct point along the bolt head, such as to form a ruler along the bolt head. A mobile transmitter-receiver is mounted to the stem of the bolt and is connected to the wire loops. The mobile transmitter-receiver has electronic circuitry therein for detecting broken loop conditions and for transmitting these conditions to a remote receiver where the conditions are related to degrees of wear on the wear plate.

Abstract: A server-side method and system are provided for defining and executing client computer applications. Aspects of preferred embodiments include defining a page table associated with a client computer application. The page table includes, for one or more application pages, a current page value, an action value, a process value and a next page value. Preferred embodiments additionally include receiving a request from a client that includes request data, an indication of a current page value and an action value. The preferred embodiments also include processing the request data. The process is defined in the page table as a process value corresponding to the current page value and action value received in the request. Additionally, the preferred embodiments include returning a response to the request. The response is defined in the page table as the next page value corresponding to the current page value and action value received in the request.
