The present invention relates to a modified crumb rubber particle having carbon to silicon bonds created by the reaction of the unsaturation in the crumb rubber particle and silicon hydride, with or without the use of a catalyst. Bound silicon content ranges from about 0.1% to 10% by weight. The silicon-modified crumb rubber can be used as is or a reinforcing filler in formulations. Typically the silicon-modified crumb rubber is used in up to 25% by weight of the total rubber present in virgin rubber compositions.

The present invention discloses a water dispersible polymer particle stabilized by a hydrophobically capped oligomeric acrylamide dispersant. The present invention also discloses a heterogeneous method for forming polymer particles comprising providing a water immiscible organic phase comprising at least one monomer dispersed in a continuous water phase and a hydrophobically capped oligomeric acrylamide, and polymerizing said organic phase to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide. Also disclosed in the present invention is a heterogeneous method for forming polymer particles comprising providing a water immiscible organic dispersed in a continuous water phase, polymerizing said organic phase, and adding bydrophobically capped oligomeric acrylamide to yield polymer particles stabilized with hydrophobically capped oligomeric acrylamide.

A method and apparatus that increases safety when employing externally focused adaptive phased array microwave thermotherapy (hyperthermia) for breast cancer treatment include microwave absorbing pads and metallic shielding to prevent undesired or stray surface tissue heating and to cushion the breast from mechanical pressure during breast compression. The microwave absorbing pads are attached on the top of the microwave waveguide thermotherapy applicators and on top of the breast compression paddles. A metallic-shielding strip mounted across the top portion of the microwave applicator aperture acts to block microwave radiation from illuminating the base of the breast and chest wall area. The patient treatment table utilizes a metallic shield to shield the body from stray microwave radiation. Combined E-field and temperature sensors within a single catheter are used to require only a single minimally invasive skin entry point for E-field focusing and measurement of the tumor temperature. Breast compression is maintained for a period of time following microwave-induced heating to accumulate additional equivalent thermal dose. Treatments incorporating the safety improvements include thermotherapy for early-stage breast carcinomas, locally advanced breast cancer, ductal carcinoma in-situ, and benign breast lesions.

A beverage dispenser includes a beverage container assembly combined by two single chamber containers, in which each single chamber container has an internal chamber and a predetermined access opening on a top, whereby the access openings are concealed and enclosed by a top closure cap assembly. The top closure cap assembly provides each single chamber container with a spout opening and at least one air holes. The top closure cap assembly further installed with at least one air tight shut off device for selectively shutting off at least one spout opening and one air hole. Whereby the improved beverage dispenser has relatively simple and low cost structure for enabling the user to selectively serve two kinds of beverage received within the two single chamber containers respectively at a time by a single hand operation for bringing great conveniences for standard households or businesses.
摘要:
A lockable cover for a ground opening such as a manhole or catch basin. The cover has a lock including a reciprocating locking bolt mounted to its underside for engagement of a lip of a surrounding support. The bolt is accessible directly from above the cover through an aperture in the cover. In one disclosed embodiment, a cover is secured to its support by a pin which extends from the cover to under a lip of the support and a lock. In another embodiment, a catch basin cover is secured to its support through a hinge connection and a lock. In another embodiment, a manhole cover is secured to its support through a pair of locks.
摘要:
A method and apparatus of treating tissue adjacent to a bodily conduit using thermotherapy, while preventing obstructions of the bodily conduit due to edema employs the circulation of warmed fluid to maintain the temperature of the bodily conduit walls and compresses the tissue to be treated to increase the effectiveness of the irradiated heat. An energy-emitting source containing catheter is inserted in a bodily conduit and is positioned in a region of the tissue to be treated so that the energy-emitting source radiates energy to the tissue to be treated. Fluid warmed to over 30° C. is circulated into and through the catheter to warm walls of the bodily conduit adjacent the catheter. The warmed circulated fluid inflates a balloon to a pressure to compress the tissue to form a natural stent that remains after the catheter and compression balloon are removed.

A method and apparatus of treating tissue adjacent to a bodily conduit using thermotherapy, while preventing obstructions of the bodily conduit due to edema employs the circulation of warmed fluid to maintain the temperature of the bodily conduit walls and compresses the tissue to be treated to increase the effectiveness of the irradiated heat. An energy-emitting source containing catheter is inserted in a bodily conduit and is positioned in a region of the tissue to be treated so that the energy-emitting source radiates energy to the tissue to be treated. Fluid warmed to over 30° C. is circulated into and through the catheter to warm walls of the bodily conduit adjacent the catheter. The circulated fluid inflates a balloon to a pressure to compress the tissue to be treated. The combination of warmed fluid over 30° C. being circulated adjacent the bodily conduit to maintain the warmth in its walls and the compression of the tissue to be treated enables a natural stent to be formed that remains after the catheter and compression balloon is removed.
