  • Patent number: 8020085
    Abstract: The creator or author of the Web document or page at the Web site source of the page is enabled to prioritize all of the hyperlinks to other Web documents embedded in the Web page in order to optimize the needs such as the business needs of the host. The prioritization is applied in the determination of the order in which the Web documents linked to the activated embedded hyperlinks in the Web document are to be accessed. The system is implemented through the inclusion of a hypertext markup language tag associated with each of the prioritized hyperlinks indicative of the priority level of the associated hyperlink. The implementation for designating a priority level for each of the hyperlinks may be enabled to change any previously designated priority levels for said hyperlinks. Such changes in any previously designated priority levels could be made applicable to the priority levels in previously distributed copies of said Web document.

A block mechanism is located in the housing and includes a second electrical contact and a stopper disposed in mechanical communication with the second electrical contact. The stopper is positionable in the block mechanism, wherein a change in the position in the stopper results in a change in a contact position of the second electrical contact relative to the block mechanism. Further disclosed is a lateral block mechanism for an electrical circuit making and breaking switch. The lateral block mechanism includes two carrier assemblies and a connecting piece located between the two carrier assembles and secured thereto. An electrical contact is located at at least one of the two carrier assemblies.
