Abstract: A ventilation system for a toilet includes a seat that forms a substantially airtight seal with an upper rim of a bowl, an aperture extending from the inner surface to the outer surface, and a conduit coupled to the bowl outer surface at a first end and forming a substantially airtight seal with the aperture. The conduit is coupled at a second end to a vent pipe, wherein the vent pipe is positioned within a wall adjacent the toilet.

Abstract: A snow vehicle includes a frame having a longitudinal axis, a pair of rear suspension assemblies, a pair of front suspension assemblies, a pair of drive tracks, and a pair of ski assemblies. Each rear suspension assembly pivotally connects a drive track to a rearward portion of the frame. Each front suspension assembly pivotally connects a ski assembly to a forward portion of the frame. The rear suspension assemblies, the front suspension assemblies, the drive tracks, and the ski assemblies are symmetric about the longitudinal axis.

Abstract: A yarn package adapter having an adjustable base for receiving and engaging a package of strand material wound about an elongate hollow core. The adapter includes a central shaft adapted to be mounted to the creel and having means mounted on the central shaft for engaging the inside diameter of the package core. The adapter also includes a base having an aperture for receiving the central shaft therealong and for forming a sliding abutment for engaging an end of the package core and a releasable locking mechanism attached to the base for engaging the central shaft and preventing movement of the base along the shaft.

Abstract: A flexible, open ended microwave cooking tube formed of paper. The paper is provided with a layer of microwave susceptor material such as vacuum deposited metal. The tube is formed of a rectangular blank of the stock comprised of the paper and microwave susceptor material. A pair of opposite, parallel ends of the blank are seamed together and are provided with handle forming holes. In operation, a food item is placed within the tube. During the cooking process, the susceptor material reaches the high temperature required to brown and crispen the food. The seamed, handle portion of the tube, not being provided with susceptor material, remains relatively unheated and is hence less dangerous to the user when the tube and food are removed from the microwave oven. The tube can be formed from a continuous length of the paper/susceptor stock and wound into a roll. Short lengths of the tube can then be cut from the roll to provide individual containers for microwave cooking.

Abstract: This invention relates to apparatus for receiving and mounting or supporting strand material packages formed by winding strand materials such as textile strands about hollow elongate cores. The apparatus has a central shaft and a plurality of sets of finger members and connecting link members mounted for movement relative to the shaft. Each set makes up, together with the shaft, a five bar linkage in which the connecting link forms an engaging means which moves into engagement with the inside surface of an elongate hollow package core as the strand material package wound about the core is mounted for use.

Abstract: This invention relates to apparatus for receiving and mounting or supporting strand material packages formed by winding strand materials such as textile strands about hollow elongate cores. The apparatus has a central shaft, a rear support mounted on the shaft for engaging one end of a package core and a plurality of fingers for engaging the inside diameter of the core. The rear support and fingers together support a package, while accommodating cores of varying types and sizes. Operation of the rear support and fingers is coordinated by a linkage and a latch which interconnect those elements and the shaft.

Abstract: A mechanical device for controlling the tension in a traveling textile yarn includes a base, a flutter member pivotably mounted on the base and a cylindrical post eccentrically mounted rotatably on the base adjacent the post, the flutter member and post being independently biased toward one another and yieldably movable independently away from and toward one another. A yarn monitoring arm is integral with the post and extends outwardly therefrom for engagement with a traveling yarn passing between the post and the flutter member. Tension increases and decreases in the yarn act on the monitoring arm to effect movement of the post in its rotational directions away from and toward the flutter member to increase and decrease the frictional drag and thereby offset the tension change. The flutter member yields to yarn thickness fluctuations and is adapted for flutter-like pivotal movement in response to yarn ballooning and untwisting actions to dampen same while maintaining the frictional drag on the yarn.
