Abstract: An on-line communications service allows a plurality of service providers to provide services to respective groups of subscribers, with the on-line service from each provider being independent of the on-line service from other providers. The subscribers' access to features is maintained through service maps which are customized by the service provider interactively with the host computer. Upon log-on, the service map is downloaded to a subscriber's computer and defines the services which can be accessed, the appearance of the user interface and navigation through the services. Data for each provider's service is maintained separately from the data for other providers. Billing can be customized for each provider.

Abstract: A device for filling the crank case or transmission of an internal combustion engine with oil dispensed from a can opened by the device. The device comprises an outer casing, a cup member in the casing spaced from the side walls and bottom of the casing, registering openings in the cup member and casing bottoms, and a piercing and dispensing tube mounted in the cup member having a beveled piercing end facing upwardly in the cup member. Air passages are provided by the space between the cup member and casing communicating with the interior of the piercing tube. The tube is mounted in the cup member by a pin of magnetic material which has two functions: to attract ferrous matter and to separate the fluid flow momentarily, thereby allowing air passing upwardly or downwardly with the fluid, to mix with the fluid. The spacing means between the cup member and the casing may be a plurality of bars connected to the side walls of the cup member and having legs extending beyond the cup member bottom.
