Title: Conversion of Non-Ferrous Matte
Inventor: MARCUSON SAMUEL W
IPC: C22B23/02
Filed: 1993-10-12
Abstract: A non-ferrous matte conversion process is disclosed in which molten non-ferrous matte, essentially nickel and/or copper sulfide and iron sulfide, isprovided in a suitable vessel, such as a modified Pierce-Smith converter. The bath is stirred from below with a non-reactive sparging gas, such as nitrogen, and surface-blown from above with an oxygen-containing gas. A flux is added to the melt to raise a fluid slag. In addition, cold crushed matte is added to the bath. The cold matte acts to maintain the temperature of the bath, so as to prevent overheatingwhich can damage the converter lining. The matte addition also serves as a source for additional converter feed. As the reaction progresses, the slag layer is periodically skimmed, and additions of flux and cold matte are made when necessary. When it is no longer possible to raise a slag, a non-ferrous sulfide matte is obtained having a greatly reduced iron content.

Patent CA-2124653-A1 (CA)
Inventor: SMITH JEREMY P
IPC: B65D83/14
Filed: 1994-05-30
Abstract: In an aerosol valve the flow path includes a compartment having an inlet into the compartment and a valve seat at the upper end of the compartment, a pocket is disposed downward from the seat opening, the pocket containing a gravity-responsive ball. When the valve is being used in dispensing and is tipped in a direction which brings the ball closer to the flow through the compartment, the ball becomes entrained in the fluid flow and flies up to seat on the valve seat to block it off, precluding further discharge. When the aerosol valve is released, a bypass raises the pressure inside the valve body so that the ball will fall away from the seat. The purpose is to avoid the escape of propellant which might occur in tipping if the lower end of the dip tube is exposed to the head space.

Title: Control for a milker unit support
Inventor: LARSON LARRY G
IPC: A01J5/04
Filed: 1994-11-28
Abstract: A support for positioning a milker unit beneath a cow has a shaft which is vertically movably mounted on a base. An arm on the shaft supports a milker unit beneath a cow. Air pressure is applied to the shaft to hold the shaft and arm at a desired vertical position.  A control automatically adjusts the vertical position of the support so that when the milker unit is attached to a cow's teats the weight of the milker unit is applied solely to the cow's teats.   The control includes a pair of valves each connected to a supply of air under pressure.   A first of the valves has an open position in which the amount of pressure applied to the support decreases and the support is permitted to lower.  A second of the valves has an open position in which air from the supply moves the first valve from a normally closed position to the open position thereof.   The control has a lever mounted on the arm for moving the second valve to the open position thereof when the milker unit applies force to the lever.
