Abstract: A method and bandsaw apparatus (30) which facilitates maintenance access to a continuous loop bandsaw blade (43) rotatably mounted thereon.  The bandsaw apparatus (30) includes a base frame (31) and a cutting table (32) supported on top of the frame (31) to provide a cutting surface (33).  A saw carriage assembly (37) is provided including a saw arm assembly (37) rotatably supporting the saw blade (43) which extends through a blade receiving slot (34) in the table (32).  A support frame (42) movably mounted to a guide assembly (44) enables selective reciprocating movement of the saw arm assembly (40) relative the cutting table (32) so that the blade (43) can move along the receiving slot (34). A coupling device (45) of the carriage assembly (37) movably couples the saw arm assembly  (40)  to the support frame (42) for movement of the saw arm assembly (40)  between a cutting position and a maintenance access position.  In the maintenance access position, when the carriage assembly (37) is positioned at the table second end (36), the saw arm assembly (40) can be moved away from the cutting table (32) which further moves the bandsaw blade (43) to a position outwardly of the slot (34).  This substantially enhances access to the blade drive wheels (41, 41') and the blade (43).

Inventor: THOMAS KURT N
IPC: B01D21/24
Filed: 1996-10-07
Abstract: In clarification systems it is necessary to have adequate actual tank retention time for gravitational separation to occur and thereby ensure a high quality output which is free of both hydrocarbons and particulates.  However, to handle produced volumes and minimize capital expenditure it is desireable to maximize tank throughput.  A method of feeding a skimming/vortex clarifier tank is disclosed.  The method achieves an actual tank retention time which is nearly 3 times that typically achieved.          The method utilises a tangential inlet convergent- divergent nozzle and has a tank discharge positioned in a bottom central portion of the tank.  An improved floating skimmer having a swinging arm is disclosed.  Additionally, a multi tank system in which a last spreader bar tank, primarily used to remove particulates, is disclosed.
