IPC: B01D46/42
Filed: 1986-06-07
Abstract: A stepped plenum system (10) is provided for distributing particulate laden gas to a plurality of filter bags in a baghouse under substantially equal flow rate and pressure conditions. The stepped plenum system (10) includes an inlet conduit (24) and a plurality of outlet conduits (12-20). Gas is inserted into inlet cross-sectional area (28) of inlet conduit (24) and is directed to outlet conduits (12 and 14) through a stepped pattern design. The first outlet conduit (such as 12) is in fluid communication with the inlet conduit (24) and the second outlet conduit (14) is further in fluid communication with the inlet conduit (24). The second outlet conduit (14) is longitudinally displaced from the first outlet conduit (12) and provides for a second flow region (42) which is of lower cross-sectional flow area than an initial flow region (30) of the inlet conduit (24). Each of the outlet conduits (12) include a plurality of inlet vane members (62) which capture and redirect the flow of the gases into a direction which channels the gaseous flow into respective conduits (12 and 14). Outlet vane members (70) are provided at the outlet sections (60) of the outlet conduits (12 and 14) to further pattern the flow egressing from the outlet conduits (12 and 14) into a filter bag area within the baghouse compartment. Through use of stepped plenum system (10), there is provided a system whereby the particulate laden gas is equally distributed to the outlet conduits (12-20), and further where differences in back pressure are minimized between the respective outlet conduits. It has been found that through the use of the stepped pattern of system (10) in combination with the inlet vane members (62) and the outlet vane members (70), that vortexes and turbulent conditions are minimized in the gaseous flow stream.

Abstract: A fault recovery method for a distributed processing system (100) where a message called a heartbeat is broadcast among the processors (41-45) once during each major processing cycle. The heartbeat message indicates the physical (PMP) and logical (LMP) identity of the transmitting processor (41) with respect to the system arrangement as well as the processor's present operational state. By monitoring the heartbeats from other processors (42-45), spare processors can autonomously take over the functions of failed processors without being required to consult or obtain the approval of an executive processor. The new physical location (PMP) of a replaced processor will be automatically recorded by the other processors. The method has application to duplex standby and resource pool configurations as well as sparing arrangements.

Abstract: A fully differential CMOS operational amplifier (10) of the folded cascode type has a differential input network (12) and a transimpendance stage (14). The transimpedance output stage (14) is made up of two similar negative and positive signal branches (32, 34) connected in parallel with each other between supply voltage nodes (V+, V-). Each signal branch includes a P-channel current source transistor (48, 60), a cascode transistor (50, 62), an N-channel pull-down transistor (40, 52), and an N-channel current source transistor (42, 54), all connected in tandem, respectively, between a positive supply voltage node and the drain of a feedback transistor (44, 56). which has its source connected to a negative supply voltage node. The drains of the feedback transistors of the two branches are joined. A second cascode transistor (64, 66) has its source connected to the source of the first cascode transistor (50, 62) and its drain connected to the source of the pull-down transistor (40, 52) to increase the output impedance at the drain of the first cascode transistor without affecting the signal current-carrying capability of the signal branches (32, 34) by permitting the cascode transistors and the pull-down transistors connected to the output nodes to have a reduced width-to-length ratio.

Abstract: in accordance with the present invention, an optimizer system is interposed between a host computer application program and a telecommunications link connecting the host computer with an addressable-buffer terminal device. The optimizer includes a computer program that causes the computer (a) to divert outgoing data streams that would normally be transmitted from the host to the device; (b) to generate new optimized outgoing data streams conforming to the communications protocol in use; and (c) to hand back each optimized data stream back for further outgoing transmission in place of the corresponding original data stream. 
     When an incoming data stream is received, the optimizer diverts it for processing; updates the present-state image of the device buffer; and creates a new incoming data stream conforming to the host's previously-noted expectations about the original incoming data stream. 
     The contents of an optimized outgoing data stream reflect the result of an exclusive-or (XOR) comparison by the optimizer of (1) a RAM image of the "updated state" of the device buffer assumed by the application program, with (2) a similar RAM image of the assumed present state of the device buffer. 
     Control codes contained in the device buffer, such as field attribute bytes, are represented in the updated-state and present-state images by unique characters that do not correspond to any data character. The optimizer programming includes the capability to deal with null suppression in some terminal devices.
