Abstract: An aquaculture pen includes an annular floatation assembly formed from a plurality of float platforms connected end to end. A weight ring is suspended from the floatation assembly by a first plurality of tension members at a central portion of the float platforms. A net support ring is suspended from the floatation assembly by a second plurality of tension members that are attached to the floatation assembly, for example, outboard of the first plurality of tension members. A mesh enclosure for the pen includes a main portion attached to the net support ring, a jump net portion that extends from the net support ring to engage the inboard side of the floatation assembly, and a top portion that closes an upper end of the mesh enclosure.

Abstract: A device for dewatering sewage sludge and a method for its use is provided. The device affords separation by causing a sludge concentrate to flow as sufficiently slow rates to cause the gel-like concentrate to fracture and release trapped water. Sewage sludge dewatered according to the method and utilizing the device can be directly burned or directly introduced into a landfill. Certain embodiments of the device can be transported to a site where the dewatering process is carried out and certain embodiments of the device can be further utilized to transport dewatered sludge from the dewatering site to a further disposal site.

Abstract: A heat and water integration process for an oil sands operation includes subjecting warm oil sands tailings to thickening to produce thickened tailings and warm water overflow; subjecting the warm water overflow to direct steam injection (DSI) to produce steam heated thickener water; providing the steam heated thickener water to a unit of the oil sand operation; and producing the warm oil sands tailings from the oil sands operation. The oil sand operation unit may be an oil sand ore preparation unit and/or a primary separation unit, for example. The heated thickener water can replace water taken from pond inventories. The DSI may use excess, low quality, wet, low pressure and/or blow-down steam. The process enables improved heat and water usage in oil sands processing.

Abstract: For a cell-phone or PDA, the rows of key-caps include respective light-strips, which pick up light from respective LEDs surface-mounted on the PCB. The light-strips are sandwiched between the key-caps and the key-switch actuators (whereby the light-strips move with the keys when the keys are depressed). Sockets for receiving the key-caps are co-molded to the light-strips. Sockets are provided in the resilient webs of the keys for receiving under-blocks co-molded to the light-strips.
