Title: Device for implanting a row of radioactive seeds and non-radioactive spacers
Inventor: ADAM MARK ALEXANDER
IPC: A61M36/12
Filed: 2003-09-19
Abstract: The invention relates to a device for implanting at least one row of X radioactive seeds and Y non-radioactive spacers with X ~ [1, 2, ...] and Y ~ [0, 1, ...] in a desired configuration to a desired location in an animal body for effecting radiation therapy of cancerous tissue in said body, said device comprising: at least one elongated hollow needle with an open distal end to be inserted towards said desired location in the body and with a proximal end to be connected to a seed loading apparatus; and at least one pushing element for implanting during retraction of the elongated hollow needle said row of radioactive seeds and non-radioactive spacers from said seed loading apparatus through said hollow needle towards said location.        The prior art rows of seeds/spacers have the disadvantage, that after insertion into the body or near to the tissue to be irradiated no physical relation between the inserted seeds and spacers exists other than through the tissue of the body, thus affecting the radiation treatment to be performed.        Therefore in order to avoid mutual displacement of the seeds/spacers after insertion of the row into the body due to movements of the patient the device according to the invention further comprises at least one tube-shaped element with at least one open end to be inserted through said hollow needle towards said desired location; and at least one tube-shaped sleeve member with an open distal and open proximal end for inserting said tube-shaped element through said hollow needle towards said desired location, wherein said tube-shaped element serves to accommodate said row of radioactive seeds and non-radioactive spacers.

IPC: F02D9/06
Filed: 2003-12-16
Abstract: An exhaust brake has a body with a passageway for exhaust gases therein. A  valve member is movably located within the passageway for selective movement between an open position where the valve member opens the passageway and exhaust gases are free to move through the passageway and a closed position where the valve member blocks the passageway and the passage of exhaust gases through the passageway. The valve member has an aperture therethrough to permit a limited flow of exhaust gases through the aperture when the aperture is open. An exhaust valve actuator mechanism is coupled to the valve member for moving the valve member between the open position and the closed position. A closure member is positioned adjacent to the aperture. The closure member has an open position where the closure member is spaced apart from the valve member and permits a flow of exhaust gases through the aperture and the closure member having a closed position where the closure member contacts the valve member about the aperture and inhibits a flow of exhaust gases through the aperture. An actuator member operatively engages the closure member.  There is a relief actuator mechanism, the relief actuator mechanism including an actuator member that operatively engages the closure member. The relief mechanism brings the closure member into operative engagement with the valve member with sufficient force, when the valve member is closed, to maintain the closure member in the closed position when the exhaust gases are below a predetermined pressure.

Abstract: A multi-layered cylinder head gasket for positioning between a cylinder head and a cylinder block of an engine includes a spacer layer and a stopper layer.  The stopper layer includes either a wave or rigid stopper positioned at a periphery of an aperture of the stopper layer. A sealing bead is positioned adjacent the stopper. Overall, the stopper layer has a generally uniform thickness. The spacer layer, however, has first and second thicknesses with the second thickness being generally less than the first thickness. The second thickness of the spacer layer mates with the stopper and sealing bead when the stopper layer and spacer layer are joined together. A transition area is positioned between the first and second thicknesses. The variable thickness of the spacer layer permits the gasket to provide generally equal sealing stresses while subjected to variable compression forces.
