Abstract: A foreign exchange pricing system includes a computer system executing a foreign exchange pricing application, the foreign exchange pricing application capable of displaying foreign exchange pricing information. A dedicated controller, including a joystick, is operatively coupled to the computer system. A user can employ the joystick to display or alter the pricing information. Preferably, the dedicated controller includes a combination of a keyboard and the joystick. The displayed pricing information will preferably relate to either spot rates or forward rates. The foreign exchange pricing system can determine that the joystick has moved in a certain position to invoke a specified procedure.

Abstract: The separation of oil from filter cake, such as a transformer filter cake, is achieved by contact mixing filter cake with protein additives in water for a sufficient time for substantially all the oil to be displaced from the filter cake, flushing displaced oil and filter medium with water in a separating device and collecting the oil and the filter medium separately. The separation occurs with little or no remediation of the oil taking place so that both the oil and the filter medium can be reused.

Abstract: Remediation of toxic waste materials in solid, liquid or a mixture of solid and liquid form provides rapid reduction of the toxic conditions to innocuous levels. The process utilizes indigenous microorganisms present in the waste materials. The process comprises contact mixing waste materials with protein nutrients in water, air entraining the waste materials and protein nutrients during mixing to form a bioactive structure, and exposing the bioactive structure to cure in air until the toxic materials are remediated to a predetermined innocuous level.
