Title: Stepping type plenum systen
Inventor: ROBAATO DABURIYUU TEISON
IPC: B01D46/02
Filed: 1986-06-30
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.

Title: Automatic welding device
Inventor: HAYAKAWA YOSHITAKA
IPC: B23K9/02
Filed: 1980-10-31
Abstract: PURPOSE: To run a head backward and stop it accurately by counting the number of the origins passed during backward running, and driving a timer of a short time from the final origin in the case of circumferential welding of stationary pipes.  
     CONSTITUTION: A welding head 3 rotates while welding the circumference of the work 1, and when it ends welding for one pass, the head 3 stops once in an end position B. Next, when a welding head backward run relay is turned on, the heat 3 starts running backward, and whether it arrives at the first origin 1 or not is judged. When the origin signal from the origin 1 is detected, 1 is added to a counter having been initially set at 0. The head 3 passes the origins 1W4 (1) before it arrives at the point A by running backward by one turn from the point B and therefore the number of the origins is set at 4. The set value and the content of the counter are compared, and this is repeated until the content of the counter coincides with the set value. When the content of the counter attains 4, the backward running timer is started. Thereafter, when the timer times up, the head backward running relay is turned off.
