An elongate spike configuration of air filter for an automotive vehicle includes a cowl arranged to extend parallel to the ram air flow about the vehicle and resulting from movement of the vehicle at speed. The cowl is rotational and is power driven in rotation during operation of the vehicle such as to smooth ram air flow, reducing turbulence and excessive ram air pressure so as to improve running smoothness of the vehicle engine.

A composite food storage container combines the advantages of glass and polymer while avoiding their disadvantages. A composite food storage container may include an outer polymer container that is configured to accommodate a glass container within the polymer container. Since the food does not contact the polymer, there are no potential concerns with chemicals leeching into the food. Since the glass is surrounded by the polymer container, the glass is protected from breakage and the composite food storage container does not become too hot to easily and safely handle upon removal from a microwave oven.

A rules based decision management system using online analytical processing (OLAP) technology for dynamic assessment of strategy results. Generally, a rules based decision management system applies strategies which produce results. The results are aggregated over time, typically in accordance with values of a discrete dimension and ranges of a continuous dimension, to prepare for the application of OLAP technology. Date stamping can be used so that, when aggregating the results, different values and different ranges can be valid for different periods of time. OLAP technology is then applied to the aggregated results, to evaluate the applied strategies.

A method and apparatus are disclosed for a thermoplastic profile wall pipe joint or weld assembly without the use of a coupler to provide for a leak free pipe joint with substantially flush interior and exterior surfaces. The pipe joint consists of configuring the two pipe ends to be joined by removing substantially all of a first wall and the helical rib from the first pipe end, removing a portion of the helical rib from the second pipe end, coupling the pipe ends together and heating the weld assembly couple to fusion weld the pipe ends together. An electrical resistance element is provided for and placed within the pipe joint to provide the required heat. Also disclosed is the use of a thermoplastic sheet with the electrical resistance element to allow the end margins of the electrical resistance element to overlap without shorting by separating the end margins radially from one another and to allow for a more uniform fusion welded pipe joint. The resulting joint is a leak free joint with no interior flow obstructions or exterior collars or protrusions without the need for a coupler.

A thermal energy storage device and method for making the same. The thermal energy storage device is in the form of a sealed tube-like container such as a tube-like cylinder or other geometrical configuration partially filled with a phase change material such as calcium chloride hexahydrate. The cylinder is made of tubular high density polyethylene and more particularly an ultra high molecular weight high density polyethylene having a molecular weight of about 500,000 to 700,000 which is tough, chemically resistant, withstands low and high temperatures, acts as a moisture vapor barrier and can be fused and sealed. The calcium hexahydrate is filled in an open top cylinder, closed at the bottom by dissolving two parts of calcium chloride dihydrate with one part of water to provide calcium chloride hexahydrate in liquid form. The cylinder is filled to about 90% by volume and a cap of the same material is then preheated to about fusion temperature. The open top of the cylinder is then brought up to fusion temperature and the cap is fused to it under pressure. The thermal energy storage device with the encapsulated calcium chloride hexahydrate can then be subjected to repeated freeze-thaw cycles. The latent heat of fusion is utilized with sensible heat in various types of usages such as solar heating, heat pump applications and the like. In another embodiment the cylinder may be pinch sealed at the bottom and top by fusion to provide a flat pinch. Modifications of pinch sealing to reduce distortion near the seal include X-shaped, Y-shaped and wave-shaped pinch seal configurations. The tube-like container instead of being cylindrical may for ease in stacking and to present greater surface area take other geometrical configurations such as a generally oblong configuration with rounded sides.

An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes pushing the filter element against a pivot region in the housing to release a seal between the filter element and the housing.
