Abstract: A label applying system includes a conveyance path for moving an item in a conveyance direction, and a label applying arm, including a free end with an associated tamp pad, the label applying arm linearly movable toward the conveyance path for applying a label to the moving item on the conveyance path. A connection between the tamp pad and the label applying arm comprises at least one rubber damper between the tamp pad and the label applying arm for enabling pivot of the tamp pad and absorbing impact force when the tamp pad contacts the moving item to apply the label to the moving item.

Abstract: A communication network that includes a signaling system seven (SS7) network is operated by associating call release messages, which are indicative of call failures in the communication network, with an originating point code (OPC) and/or a calling number. The rate at which calls originating from the originating point code and/or the calling number are admitted to the network may be adjusted based on the association between the call release messages and the originating point code and/or the calling number.

Abstract: A set of methods controls the pumping action of and provides leak checking of a solid electrolyte oxygen sensor having internal and external electrodes. A first method performs a leak check on the sensor by forcing the sensor internal reference chamber to an evacuated state while seeking a minimum pumping current able to maintain this state. Further pumping control methods apply current pulses to the sensor electrodes to achieve a balanced state between an external oxygen partial pressure and an internal reference oxygen partial pressure. Reduction expressions modify the pulse parameters as a function of the sensor voltage output. A further expression modifies the pulse magnitude as a function of the internal reference chamber oxygen partial pressure. A further expression modifies the initial value of the pulse magnitude as a function of the oxygen partial pressure in a calibration gas during a calibration process.

Abstract: Apparatus for delivering constant quantities of fluid, comprises a chamber, a piston (6) reciprocally movably within the chamber, a fluid inlet (3) to the chamber on one side of the piston, and a fluid outlet (5) from the chamber on the other side of the piston (6). A valve (12) through the outlet side of the chamber to the fluid outlet (5). Spring means (10) urges the piston (6) and subsidiary spring means (16) urges the valve (12) through the piston (6) towards the inlet side of the chamber, such that fluid pressure on the inlet side of the chamber will cause the piston (6) to move to eject a predetermined quantity of fluid from the outlet side, and on the return stroke fluid will flow through the valve (12) in the piston (6) to refill the outlet side for the subsequent piston delivery stroke.
