Abstract: A tomato peel material acidification system (10) including a receiving tank (32), a pump (36), acid injection devices (46, 48), mixing devices (38, 39), and a return line (52) for recirculating tomato peel material with an acid level that is too high. PH sensor probes (56, 58, 60) test the pH level of the tomato peel and acid mixture and appropriate controls direct the opening and closing of valves (50, 51, 54, 55) to re-direct the mixture back into the receiving tank.

Abstract: Methods for fabricating single and multilayer printed boards which employ electronically conductive adhesive compositions are provided. The composition comprises a solder powder, a chemically protected cross-linking agent with fluxing properties and a reactive monomer or polymer as the principal components. The compositions may also comprise three or more of the following: a relatively high melting metal powder; solder powder; the active cross-linking agent which also serves as a fluxing agent; a resin; a reactive monomer or polymer; and a metal additive. Compositions comprising metal powder are ideally suited for creating the conductive paths and vias on printed circuits.

Abstract: A transfer mechanism for transferring groups of plastic containers from a continuously moving transport conveyor to a tray includes container sensors and a mechanism for providing correct in-fee timing of the containers. The tray is advanced after each group of containers is deposited therein and when the tray is full, it is removed.
