Title: Electrical circuit interrupting device with means to break welded contacts
Inventor: TURNER DAVID C
IPC: H01H71/50
Filed: 1994-06-06
Abstract: ABSTRACT OF THE DISCLOSURE     The movable contact arm 17 of a circuit bleaker 1 is mounted on a pivot pin 2 by a slot 29 which extends generally transverse to the longitudinal arm 19 of the contact arm, so that when the contacts 9 are welded, initial motion of the circuit breaker operating mechanism 43 to open the contacts 9 is translated into pivoting of the contact arm 17 about, and thereby beaking the weld. In a circuit breaker 1 in which the contact arm 17 is coupled to the operating mechanism 43 through a cam mechanism 75-85 which allows the contact arm 17 to blow open in response to very high overcurrents, the slot 29 extends generally longitudinally so that the cam mechanism 75-85 translates initial movement of the operating mechanism 43 into longitudinal movement of the contact arm 17 to apply a shear force tending to break the weld.

Title: A process for making a paper based product containing a binder
Inventor: KINSLEY HOMAN B JR
IPC: D21H21/52
Filed: 1993-02-10
Abstract: Provided is a process for making a paper based product which comprises first preparing a slurry of a cellulosic pulp; a particulate binder substantially insoluble in water, and an emulsion comprised of lecithin and a fatty acid or derivative thereof. This slurry is then drained of liquid to form a web, with the web being dried to provide the paper based product. The preferred polymeric binder is a hydrolyzed polyvinyl alcohol powder, which binder can be present in the final dried product in amounts of up to about 20 weight percent or more. The use of the emulsion comprised of lecithin and a fatty acid or derivative thereof permits a web containing such a high amount of sticky polymeric binder to be dried at high temperatures, without the web sticking to the drying cans generally used in commercial processes. The process of the present invention thereby permits one to efficiently prepare such a paper based product using conventional, commercial papermaking machinery.

Title: A procedure for manufacturing refractory crucibles for steel-processing ladles
Inventor: MIDDELDORF THOMAS FERDINAND
IPC: F27B14/10
Filed: 1994-06-03
Abstract: The process for manufacturing refractory crucibles for a steel processing ladle, in which aluminum deoxidation is carried out for the total quenching of molten steel, is such that a monolithically hardening refractory mass with a proportion of silicon dioxide is placed between an inside wall of the ladle and a reusable plug that is installed therein. After the plug has been removed, the ladle is put into use again, at which time a layer that contains alumina builds up on the hot side of the refractory crucible and a highly sintered layer of greater hardness forms behind this. It is intended that a process such as this should simplify the reestablishment of the refractory lining when the limit of use is reached, in view of the use of a layer that contains alumina and the highly sintered layer located behind this on the inside wall of the crucible. To this end, after a number of charges have been processed, a second crucible is installed as an expendable crucible within the first crucible, which now forms a safety crucible, this being done with the help of an appropriately smaller plug; when this reaches its limits of use it is broken out and the layer is reinstalled.
