Additionally, the shield can be sized to maintain an appropriate press-fit that does not compress the inner race beyond an acceptable inside diameter.

Abstract: A drain valve insert employs a stamped sheet metal body to support a threaded nut in an elevated position over the drain opening of a filter cartridge. Multiple fluid flow passages are defined between the polygonal periphery of the nut and the generally cylindrical sheet metal body of the insert. The insert body defines ledges to support the nut at its periphery corners and includes structures that prevent rotation of the nut relative to the insert body. Retaining arms project upwardly from the insert body and are bent over the nut to axially retain the nut seated against the ledges. The insert body and the nut are inexpensively formed in separate automated operations. Assembly of the nut into the insert body may also be automated.

Abstract: The magnetic separator has a tank with a pair of dual conveyor chains, spaced apart, at opposite sides of the tank. A plurality of frames with spaced apart magnetic rods are suspended from the conveyor chains in a manner allowing the frames to swivel and always hang vertically as the chains traverse their endless path. The liquid in the tank flows through the frames and ferrous particles are attracted to the magnetic rods. The rods are cleaned and the ferrous particles removed at a wiping station. Each frame has a scraping edge which contacts the bottom of the tank and drags out the non-magnetic particulate which has separated from the liquid.

Abstract: A system is described for mapping a secondary address to a primary address. The secondary address is used as an alias for the primary address and the primary address references a remote data object, such as an internet web page. The secondary address has a prefix portion that is used to direct a mapping request to a remote database storing mapping data and then a suffix portion of the secondary address is used to index within that remote database to identify the primary address. The primary address and the secondary address may be internet URL addresses. A local cache within a user device may be provided, such as in the form of a browser plug-in. Once the mapping has taken place to establish the link between a secondary address and a primary address, thereafter communication can take place directly between the user device and the target without requiring further mapping.

Abstract: A primary address formed of alphanumeric characters is difficult to enter via the small, possibly numeric only keypads of many user devices. The primary address may be an internet URL address. A secondary address is used formed of an alphanumeric prefix followed by a purely numeric suffix. The alphanumeric prefix may be specified by a shortcut key on the device and then the numeric suffix entered using the normal numeric keypad. A remote database server receives the secondary address and stored mapping information that converts this to a primary address. The primary alphanumeric address is then used to forward the request received from the user device onto the web site server for the target data object. The web site server responds directly to the user device.

Abstract: This invention relates to data processing systems. More particularly, this invention relates to the addressing of remote data objects, such as, for example, internet web pages, via a computer network, such as, for example, the internet.

Abstract: An apparatus for filtering machine coolant which includes a filtering belt conveyor having a series of bars on the outer surface of the filtering belt conveyor. The filtering belt conveyor is located inside of a tank along with a separate drag conveyor which removes fines that are sprayed off the filtering belt conveyor. There is a partition in the tank between the filtering belt conveyor and the separate drag conveyor.

Abstract: A filtration apparatus designed to remove solid contaminants from a liquid includes an endless filtration belt located in a liquid tank, so that liquid flows through minute openings in the belt into a liquid collection box located within the belt envelope. Edge areas of the belt are engaged with annular support walls carried by the tank side walls, such that a continuous seal is provided against migration of contaminants around the belt side edges. Contaminants collecting on the belt surface can be periodically removed by moving the belt across a spray system that dislodges the contaminants from the belt into the tank. A drag conveyor removes contaminants from the tank.

Abstract: A water line freeze protection system consisting of first and second branch pipes extending from a water service pipe, a water holding tank, a metering orifice between the first branch pipe and the holding tank, a pump and a check valve between the holding tank and the second branch pipe, the check valve permitting flow of water only in the direction from the pump to the second branch pipe, a float and switch secured to the holding tank to activate the pump at an upper water level and deactivate the pump at a lower water level, and an overflow pipe from the holding tank to pass water from the holding tank into a drain when the pump is none operational.
