Title: Walking beam furnace - with constant rapid heating residence time during cycle changes by specified anticipatory step changes
Inventor: KNAAK RUEDIGER DIPL ING DR
IPC: F27D3/00
Filed: 1978-09-12
Abstract: A walking beam furnace for the heat treatment of alloy steel raises the temperature to 800 degrees C at a limited rate in a preheating section. It the subsequent rapid final heating section the end temperature is reached quickly. To change the average cycle time Tt which is demanded e.g. by a following rolling mill program change, the new transport spacing A and transport spacing time TA are adopted a certain time before the program change. This time Ts equals the desired residence time in the rapid heating section. This saves having to run the furnace empty before any program change, yet it ensures that the retention time Ts, which govens the decarburization of the surface layers of the heat treated steel, is maintained. The down-times of the rolling mill are thus eliminated.

Title: Container drainage volumetric flow regulation actuator - has drain cock baffle operated via lever and pivot from float
IPC: G05D7/01
Filed: 1979-10-13
Abstract: An actuator for draining containers is esp. applicable to agricultural tankers. A controller regulates the flow from a drain cock according to residual fluid level so as to maintain an constant volumetric flow rate. The actuator has a partic. simple construction. A baffle (6) inside the drain cock (2) outlet aperture varies its flow cross-section according to the vertical position of a float (10) to which it is linked (9). The float height varies with the liquid level (11) in the tank (1). As the fluid level subsides the baffle is actuated so as to increase the flow cross-section. The baffle (6) position is varied by a lever (9) and swivel (7) mechanism attached to the float (10). The baffle is smaller than the drain cock cross-section and hence leaves a residual flow cross-section when fully closed.
