Title: Metallurgical vessel having at least a trough-wall electrode
Inventor: HAMY MICHEL
IPC: H05B7/06
Filed: 1991-02-07
Granted: 2002-10-15
Abstract: The metallurgical vessel, such as a direct-current arc furnace, comprises a metal housing (1) lined on its inside with refractory material (2), at least one electrode (3) passing through the bottom of the vessel and connected to a terminal of an electrical power supply, the electrode being fastened to the metal housing by a mechanical fastening arrangement and insulated electrically from the housing. A leaktight wall (20) surrounding the fastening zone of the electrode prevents a liquid flowing over the inner surface of the housing from coming into contact with the electrode fastening arrangement, and orifices (26) are provided for discharging the liquid collected out of the housing. The invention is particularly applicable to direct-current arc furnaces and prevents the molten lead originating from the scrap metal of the charge and infiltrating through the refractory from damaging the electrical insulation of the fastening of the electrode.

Title: Method for molding polypropylene resin
Inventor: HARA TAKAHISA
IPC: B29C45/00
Filed: 1991-10-04
Granted: 1999-07-06
Abstract: The present invention is directed to a method of producing a foamed article of a polypropylene resin.  The method comprises the steps of providing a pair of male and female molds which are slidably engaged and which have a freely set cavity clearance.  A polypropylene resin melt containing a chemical blowing agent is supplied to the male or female mold when the cavity clearance is 1.0 mm or less.  One of the molds is moved to increase the cavity clearance while the polypropylene resin is being supplied so that the pressure on the resin melt is adjusted in a range between 5kg/cm2 and 100kg/cm2. As soon as the resin supply is finished pressure is applied to form a skin layer on the resin melt and further increasing the cavity clearance to form a foamed core layer.          The foamed article is allowed to cool in the mold.  The method of the present invention is suitable for preparing embossed polyvinyl chloride leather lined with a fabric.
