Title: Sludge scraper for settling tank floor - is mechanically lowered at intervals by gap in side rails
Inventor: HAVERKAMP WILHELM
IPC: B01D21/04
Filed: 1979-06-09
Abstract: Sludge scraper plate travels longitudinally along the floor of a setting tank and is held by a tube mounted at its ends on rollers running along a lower rail and returned by motor-tensioned cable along an upper rail to the starting position. At intervals the lower rail has arcuate bends occupied by toothed rotors and followed by a gap with a rotary closure. When the closure is open the scraper can descend to the floor and end-switch is actuated to start the scraping. When the closure is shut, the scraper continues along its original path to a similar gap, or completes its full journey. The change -over mechanism can be altered to give specific scraping cycles. The scraper need not invariable traverse the full length of the rail but may be recycled to rescrape specific lengths a number of times before passing to a less heavily-settled length, without requiring an added cable and/or motor.

Title: Mag arc welding gun using both argon and carbon di:oxide - where the proportion of argon can be reduced, thereby decreasing welding costs
Inventor: SCHMIDTKE WOLFGANG
IPC: B23K9/173
Filed: 1979-10-11
Abstract: The two gases are fed separately through the nozzle of a welding gun, the argon flowing through an annular tube surrounding a tube through which the electrode wire travels. Tube is surrounded by an outer nozzle forming a ring cavity through which CO2 flows to surround the Ar just above the welding zone. The ratio of CO2:Ar is pref. between 1:1 and 10:1, esp. using 6-7:1, or CO2 contg. 10-50% argon. The pref. gun nozzle contains two axial tubes used for the feeding of the electrode wire and the Ar. Similar conventional practice uses Ar and CO2 which are mixed together before being fed to the gun; and conventional mixts. contain up to 80% Ar, which is a very expensive gas. The invention eliminates mixing the gases outside the tube, and greatly reduces the amt. of Ar required, thus reducing cost.
