Abstract: An electric blanket including a flexible sheet-like heating element, a shell comprising two flexible sheets covering the heating element, one or more welds coupling the sheet of the shell about the edges to hermetically seal the heating element there between; and a flexible insulating layer extending over the heating element and covered by the shell providing at least one of thermal insulation and electrical insulation, wherein the heating element is held in position between the two sheets of the shell without using connectors that pierce the two sheets.

Abstract: An electric blanket or pad for warming a living body including a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges. A shell formed of layers of flexible sheets covering the heating element and sealed with a weld. The weld coupling the sheets of the shell about the edges to hermetically seal the heating element therebetween. The weld may be an RF weld, ultrasonic weld, or a heat bond, wherein the sheets comprise PVC.

Abstract: A flexible heating subassembly, which may be incorporated in an electric warming blanket or any other type of flexible heater, includes a single heater, which is preferably formed from an electrically conductive polymeric fabric. The subassembly further includes first and second conductive bus bars, each extending alongside a respective first and second edge of the heater, each being coupled to the heater by at least one row of stitching that extends along the respective bus bar. The edges of the heater may be folded over respective bus bars for coupling and each of the bus bars may terminate just beyond opposing ends of the heater. A ribbon of conductive material may be interposed between each of the bus bars and the heater.

Abstract: An electric warming blanket for warming patients during surgery and other medical procedures includes a flexible heater and a temperature sensor assembly coupled thereto; a first layer of water resistant material coupled to a second layer of water resistant material, about a perimeter of the heater, forms a substantially hermetically sealed space for the heater and the temperature sensor assembly. The blanket may further include a thermal insulation layer disposed between the temperature sensor assembly and the first layer of water resistant material. The temperature sensor assembly may provide input of an average temperature over a portion of a surface area of the heater to a temperature controller, when the heater and sensor assembly are coupled to the controller.

Abstract: A patient warming blanket includes a pouch and a flexible heating assembly. The flexible heating assembly is enclosed within the pouch and includes, at least in part, a flexible sheet-like heater and a temperature sensor assembly attached to the heater in proximity to a surface thereof; a visible marker is located on an exterior of the pouch to identify a location of the temperature sensor. A method for covering a patient with the patient warming blanket, in order to effectively warm the patient, includes viewing the marker so as to position an area of the blanket, which corresponds to the sensor location, for direct contact with the patient, when the blanket is placed over the patient.

Abstract: A hydraulic fastener for mounting bearing assemblies on the end of a roll in a rolling mill stand. The fastener includes a hydraulic ring cylinder component having a front face directed toward a roll and an inner cylindrical surface adapted to fit onto a reduced diameter end section of the roll. A chamber extends about the circumference of the cylinder component and is open at the front face. A hydraulic ring piston component is slidably received in this chamber and has an inner face. A retaining ring is threadedly mounted in the cylinder component to hold at least a substantial portion of the piston in the chamber. Passageways are provided in the cylinder component for injecting grease into the chamber and into a space formed between the inner face of the piston and an opposing face of the chamber. A split ring is secured on the end section of the roll to retain the cylinder component in place.
