Patent number: 5855714Abstract: A roll splicing system and method is used to splice a new roll to an expiring roll of material. Each roll includes an adhesive region disposed proximate a trailing end of the strip of material rolled around a core region of the roll. As an expiring roll expires or unrolls, the adhesive region is exposed and adheres to an adhesive adherable region on the leading end of a new roll that is rotating against the expiring roll in an opposing direction. The leading end of the new roll is thereby effectively spliced to the trailing end of the expiring roll. A trailing non-adherable region is disposed opposite the adhesive region so that the trailing non-adherable region contacts the adhesive region when rolled and prevents the strip of material from sticking to the adhesive region. The roll splicing system and method can be used to splice strips of material having adherable surfaces on both sides or having a non-adherable surface, such as a silicone coating, on one side of the strip of material.Type: GrantFiled: September 9, 1996Date of Patent: January 5, 1999Inventor: Mat G.

Buffered nitrogenated carbon overcoat for data recording disks and method for manufacturing the same
Patent number: 5855746Abstract: A method for manufacturing a recording medium on a hard disk includes forming a data recording layer on the disk, forming a nitrogenated carbon overcoat layer over the data recording layer, (with or without intervening layers), and the processing data recording layer to protect it from the nitrogen used in the process of forming the nitrogenated carbon. In one approach, the step of processing the data recording layer is accomplished by forming a buffer layer between the data recording layer and the overcoat layer by depositing carbon on the data recording layer using a carbon deposition process excluding nitrogen, then forming the overcoat layer by depositing carbon on the buffer layer using a carbon deposition process that includes a nitrogen source.Type: GrantFiled: February 28, 1996Date of Patent: January 5, 1999Assignee: Western Digital CorporationInventors: Chanapatna Krishnamorthy Prabhakara, Amrik Singh Lehil, Stella Zofia Gornicki, Keith Samuel Goodson, Wing Tsang Tang -
Patent number: 5855747Abstract: Coatings are described to improve the performance of cathodic protection systems used in water heater tanks. Semi-permeable sparingly soluble films of silicates and other organic resins protect critical areas of sacrificial anodes from concentrated usage which could sever their tank connections, yet preserve the total amount of protection available. They reduce usage of these more active anode areas and return them to service after less active ones are used up, and when the corrosion rate of exposed metal in the tank has been reduced by prolonged service, thus further extending anode life. Other coatings reduce usage of the entire anode in high conductivity waters and in electric heaters where such protection is rapidly consumed by secondary chemical reactions or absorbed by electric heating elements. These coatings also prevent complete deactivation of the anode by oxides, and bacterial interactions which generate objectionable odors.Type: GrantFiled: April 4, 1997Date of Patent: January 5, 1999Assignee: AOS Holding CompanyInventor: Donald I.

Patent number: 5855752Abstract: An apparatus for cleaning a gas sensor and a method therefor are disclosed. A high voltage is supplied to a heat generating body of the gas sensor for a certain period of time to generate a large amount of heat within a short period of time so as to remove the moisture or miscellaneous gases absorbed into on the surface of the gas sensor, thereby stabilizing the characteristics of the gas sensor. The apparatus includes: a power supply section for receiving an ac voltage from a commercial ac power source to convert it into a rated voltage and an excessive voltage exceeding the rated voltage; and a switching section for supplying the rated voltage to the gas sensor after supplying the excessive voltage of the power supply section to a heat generating body of a gas sensor for a certain period of time.Type: GrantFiled: January 23, 1996Date of Patent: January 5, 1999Assignee: Samsung Electro-Mechanics Co., Ltd.Inventor: Byeong Sung Min

Patent number: 5855753Abstract: A method apparatus is provided for electrophoretically depositing particles onto an electrode, and electrohydrodynamically assembling the particles into crystalline structures. Specifically, the present method and apparatus creates a current flowing through a solution to cause identically charged electrophoretically deposited colloidal particles to attract each other over very large distances (<5 particle diameters) on the surface of electrodes to form two-dimensional colloidal crystals. The attractive force can be created with both DC and AC fields and can modulated by adjusting either the field strength or frequency of the current. Modulating this "lateral attraction" between the particles causes the reversible formation of two-dimensional fluid and crystalline colloidal states on the electrode surface. Further manipulation allows for the formation of two or three-dimensional colloidal crystals, as well as more complex "designed" structures.Type: GrantFiled: November 26, 1996Date of Patent: January 5, 1999Assignee: The Trustees of Princeton UniversityInventors: Mathias Trau, Ilhan A.

Patent number: 5855756Abstract: An electrorefining cell permits increased electrolyte flow rates while maintaining the slime layer at the bottom of the cell and on the anode faces substantially intact. The cell includes an inlet manifold located near the bottom of the cell and having a plurality of discharge orifices for the electrolyte solution. An inlet baffle shrouds the discharge orifices to regulate and direct the flow of electrolyte solution within the cell. The inlet baffle and the cell wall form an elongated slot that resides beneath the surface of the electrolyte solution. An analogous configuration is employed for electrolyte discharge to enable relatively high electrolyte flow into and out of the cell. The specific shape, size, and location of the inlet baffle and an outlet baffle may be selected to optimize the electrolyte flow characteristics of the cell.Type: GrantFiled: November 20, 1996Date of Patent: January 5, 1999Assignee: BHP Copper Inc.Inventor: Gerald C.
