Abstract: An exhaust system is provided for a snowmobile having a front portion in which an engine is mounted, a rearward portion, and a track belt for propelling the snowmobile. The track belt is in a track belt tunnel that extends from behind the engine to a rear portion of the snowmobile. The exhaust system includes an exhaust pipe that extends from an exhaust outlet of the engine to the track belt tunnel. At least one exhaust outlet is located within the track belt tunnel at a position within the inner circumference of the track belt.

Abstract: A system and method for producing proportionately accurate likenesses in an artwork is presented. The system uses a grid or other distance markers on a transparent surface of a card. By observing a measurement of a feature of a subject with the distance markers and transcribing the measurement of the feature on the artwork an accurate likeness of the subject may be made.

Abstract: This invention relates to the use of suspended materials as a backdrop for photography or stage productions. The suspended materials may be stored on a spool device. Such spool devices may include tubes or spindles constructed of metal, of cardboard, of plastic or other lightweight and inexpensive materials. The spool device may also include means for attaching the tube or spindle to a lifting device. Such attachment means may include a pair of interconnectable coupling devices, one fixed to the spool and the second attached to the lifting device.

Abstract: A method for increasing the power output of an internal combustion engine is presented. The increase to the power output of the engine may be accomplished by injecting a pressurized oxygen enhancer, such as nitrous oxide, into the air intake of the internal combustion engine. A portion of the pressure derived from the injection is captured by a pressure port. The captured pressure is delivered to the fuel control device of the internal combustion engine such as the float bowl of a carburetor causing an increased quantity of fuel to enter the engine. A manifold for delivering nitrous oxide or another oxygen enhancer to the air intake of an internal combustion engine is also presented.

Abstract: Compositions and methods for the therapy and diagnosis of cancer, particularly ovarian cancer, are disclosed. Illustrative compositions comprise one or more ovarian tumor polypeptides, immunogenic portions thereof, polynucleotides that encode such polypeptides, antigen presenting cell that expresses such polypeptides, and T cells that are specific for cells expressing such polypeptides. The disclosed compositions are useful, for example, in the diagnosis, prevention and/or treatment of diseases, particularly ovarian cancer.

Abstract: Compositions and methods for the therapy and diagnosis of cancer, such as colon cancer, are disclosed. Compositions may comprise one or more colon tumor proteins, immunogenic portions thereof, or polynucleotides that encode such portions. Alternatively, a therapeutic composition may comprise an antigen presenting cell that expresses a colon tumor protein, or a T cell that is specific for cells expressing such a protein. Such compositions may be used, for example, for the prevention and treatment of diseases such as colon cancer. Diagnostic methods based on detecting a colon tumor protein, or mRNA encoding such a protein, in a sample are also provided.

Abstract: Compositions and methods for the therapy and diagnosis of cancer, such as ovarian cancer, are disclosed. Compositions may comprise one or more ovarian carcinoma proteins, portions thereof, polynucleotides that encode such portions or antibodies or immune system cells specific for such proteins. Such compositions may be used, for example, for the prevention and treatment of diseases such as ovarian cancer. Polypeptides and polynucleotides as provided herein may further be used for the detection and monitoring of ovarian cancer.
