摘要:
A dynamic vertical network management system is adapted to broker, between each publisher of a group of publishers and each advertiser of a group of advertisers, the sale of at least a portion of the each publisher's inventory of advertisement impressions. At least a portion of the advertisers are clients of a dynamic vertical network operator (DVN) with the DVN purchasing inventory from the publisher and utilizing such purchased inventory to fulfill advertising orders placed by the client with the DVN (network orders). A publisher data store stores, for each publisher of the group of publishers, a group of segmented ad placements. Each segmented ad placement comprises: i) a placement ID identifying an advertisement placement region within a web page; and ii) at least one distinguishing traffic attribute parameter. An advertisement-order data store stores, for each segmented ad placement, a group of advertisement orders. Upon receiving an ad request from an end user system rendering the web page, an order delivery system: i) determines the selected ad placement, ii) determines an open order for the selected ad placement meeting selection criteria, and iii) if such order is a DVN order: a) determines a client network order meeting network order criteria, and b) delivers ad content associate with the selected network order.

A sonic drilling head includes a spindle which is both rotated and vibrated at sonic frequency to effect ground penetration of members such as drill rods, etc. Two pairs of rotating eccentric masses are mounted in a sine generator housing. The pairs of masses have intersecting axis. A spiral bevel gear and drive shaft rotate the first pair of masses which engage the second pair of masses so that the pairs of masses are driven in opposite directions. Rotation is imparted to the spindle through a geared bearing isolated by a pack of precision disc springs, which also cooperate with a second set of precision disc springs to isolate the vibrations of the rotating eccentric masses from an outer housing of the sonic drill head.

A manually shiftable actuator-position input member and an actuator-operator feedback member cooperate as switch means for controlling the operation of an actuator including a rod connected to be reciprocably driven by a reversible electric motor. The input and feedback members normally occupy neutral positions relative to each other wherein electrical current is disconnected from the motor. Energization of the motor to cause it to drive in the forward and reverse directions may respectively be accomplished by moving the input member in opposite first and second directions from its neutral position. The distance through which the input member is moved preselects the distance through which the motor drives the rod, the motor driving the feedback member via the rod such as to restore the neutral positions of the input and feedback members when the rod has been driven to the preselected position.

An applicator tool for applying a liquid onto a surface of a floor includes an applicator and a handle connected to the applicator. The applicator includes a housing having a bottom surface and a plurality of sidewalls. The bottom surface is connected to the sidewalls to define a reservoir. The bottom surface has at least one opening in fluid for substantially continuously dispensing the liquid.
