Abstract: Olive oil is recovered from olives by separating olive pits from olives to obtain a pitless olive meat, by maintaining the pitless olive meat at a temperature of about 70.degree. F. to about 110.degree. F., by introducing the pitless olive meat to an extraction zone, by withdrawing a liquid phase comprising olive oil, water, and a minor proportion of pulp from a first portion of the extraction zone, and by withdrawing a substantially dry solid olive pulp from a second portion of the extraction zone. The pulp and water are separated from the oil to obtain a pure olive oil. An inert additive is mixed with the pitless olive meat before extraction to increase the yield of product olive oil. Where olive culls are used as the starting material, the culls are wetted before the pits are separated.

Abstract: A self-cleaning screen and method for screening water for hydraulic turbine intake diversions is disclosed. A check dam is established across a river on the downstream side of a side channel weir which is at a lower elevation than the dam. A fish transport trough is laterally spaced from the weir at a lower elevation and has an inlet upstream of the weir and an outlet downstream of the dam. A screen having a concave profile is connected between the weir and the trough to remove debris from water flowing over the weir. Water flowing through the screen enters a separate channel under the screen for diversion to a hydraulic turbine inlet water application. Intermittent surges of water over the weir flush debris off the edge of the screen into the trough to clean the screen.

Abstract: Olive oil is recovered from olives by separating olive pits from olives to obtain a pitless olive meat, and by continuously introducing the pitless olive meat to to an extraction zone, by continuously withdrawing a liquid phase comprising olive oil, water, and a minor proportion of pulp from a first portion of the extraction zone, and by continuously withdrawing a substantially dry solid olive pulp from a second portion of the extraction zone. The pulp and water are separated from the oil to obtain a pipe olive oil. An inert additive is mixed with the pitless olive meat before extraction to increase the yield of product olive oil.
