Abstract: A rotating machine including a rotating shaft: a plurality of conductive rotor bars spaced from the rotating shaft and fixed to the rotating shaft through at least one intermediate member, where at least one of the plurality of conductive rotor bars have at least one first internal conduit; and a circulator for establishing a coolant circulation through the first internal conduit.

Abstract: The reactive ion etching resistance of radiation sensitive resist composition is enhanced by adding at least one organometallic compound to a radiation sensitive polymer. The resist composition can be patterned and used as mask for patterning an underlying layer.

Abstract: The present invention pertains to an apparatus for cryosurgery. The apparatus comprises a cryoneedle having a diameter less than 3.2 mm. The apparatus is also comprised of a thermal insulation shell disposed about a portion of the cryoneedle for reduction of heat transfer from surrounding tissues or freezing prevention of surrounding tissues during application of the cryoneedle with the shell. The cryoneedle and shell are configured for insertion into a body of a patient. The present invention pertains to a method for freezing tissues. The method comprises the steps of bringing into contact a cryoneedle having a diameter of less than 3.2 mm with a patient's body. Next, there is the step of flowing the cryofluid through the cryoneedle.

Abstract: A vent for a mold having a mold cavity comprising a vent main body, a valve closure member having an upper end face for positioning at the surface of the mold cavity, the valve closure member being moveable with respect to the vent main body for opening and closing the vent, a spring opening mechanism formed integrally with the vent main body for opening the vent, and a valve seat between the valve closure member and the main body wherein the vent is closed by material in the mold cavity contacting the upper end face of the valve closure member.

Abstract: A vent for a mold comprising a valve closure member and integrally formed spring opening mechanism for opening the valve closure member such that when mounted in an air release vent the valve closure member may open or close said vent.

Abstract: The system includes a mechanism for freezing tissue in a patient. Additionally, the system includes a mechanism for heating other tissue near the tissue being frozen by the freezing mechanism such that essentially only desired region is frozen by the freezing mechanism and heat from the heating mechanism prevents the other tissue from being frozen. The heating mechanism is disposed adjacent to but separate and apart from the freezing mechanism. Alternatively, the mechanism for heating can be used with tissue already frozen by the freezing mechanism. A method for performing cryosurgery on a patient. The method includes the steps of inserting a cryoprobe into a patient. Next, there is the step of placing a cryoheater in contact with the patient adjacent the cryoprobe. Then, there is the step of activating the cryoprobe and the cryoheater so the cryoprobe freezes desired tissue in the patient and the cryoheater heats other tissue around the desired tissue so the other tissue is not frozen by the cryoprobe.

Abstract: A structure and method for removing and recovering an anodically bonded glass device from a substrate using a metal interlayer interposed between the glass and the substrate is provided. As used in semiconductor mask fabrication, the structure comprises a silicon wafer substrate coated with a membrane on which a metal interlayer is disposed. The metal interlayer and a glass device are anodically bonded together. Recovery of the glass device is accomplished by chemically and mechanically removing the wafer and its membrane from the metal interlayer. The membrane is preferably removed using reactive ion etching to which the metal interlayer is resistant. The metal interlayer is then removed from the glass device using a highly corrosive chemical solution. The recovered glass device may then be reused.

Abstract: A self-contained, independently operable closed wound suction evacuator which is comprised of a box-like internal body structure disposed within a fluid tight, flexible outer pouch. The pouch includes an inlet/outlet valve for providing communication between the interior of the pouch and the atmosphere of the interior of the pouch and a drainage tube. The box-like internal body structure is capable of being in an engaged position or in a disengaged position. In the disengaged position, the internal box-like structure can remain in a flat condition without causing the tensioning member to be stretched or activated. When ready for use, the internal structure can be manually expanded into its box-like structure. When fully expanded the internal structure will become engaged, hence engaging the tensioning member. Subsequent compression of the internal structure to its flat position stretches the tensioning member and activates the evacuator.

Abstract: The invention disclosed is a means of fastening flexible elastic tubing, such as silicone rubber, to a rigid connector. The invention allows for a liquid and gas tight, secure connection without the use of any bonding materials between the tube and the connector and without any external ribbing, threading, texturing, barbing, etc. of any kind on the connector and without any external clamping mechanism used to keep the tubing firmly attached to the rigid connector.The invention allows for the rigid connector portion of a component, such as a wound drainage surgical needle, to have a very smooth cylindrical surface. The use of a smooth surface with no other adhering mechanism to assist in making a secure connection that will not easily pull off is contrary to what is taught in the art.

Abstract: A grounding cable clip which may be easily snapped onto and removed from a grounding pad and which may be used to monitor the circuit continuity before and during its application to the patient.

Abstract: A mid-stream urine collection device whereby the specimen container is kept completely uncontaminated before, during and after use. The collection device includes a container and a container closing lid having an opening therein. A funnel assembly is mounted over the lid having a funnel member which extends through the opening in the lid. A funnel cover is mounted over the funnel assembly and a seal is provided on the device and which is adapted to be removed from the device and to be applied to the lid and over the opening therein to close the opening in the lid after the container is used.
