Title: Sealing system for an unloader
Inventor: STERNENBERG JAMES E
IPC: B65D39/00
Filed: 1994-06-28
Abstract: A sealing system for a plug-type unloader includes a bonnet having a guide bore with a stem reciprocably mounted within the guide bore. One end of the stem is affixed to a plug and the other end of the stem is connected to an actuator. A bellows member is positioned around the stem within the plug. The bellows member includes an expandable and contractible bellows having one end attached to the bonnet and the other end attached to the stem. Static seals are provided between one end and the bonnet and the other end and the stem. The bellows between the ends allows the bellows member to expand and contract as the stem reciprocates within the unloader. No dynamic seals are required. The plug of an unbalanced unloader includes a bore slidingly receiving an adapter around the bellows member to protect the bellows member from the pressure pulsations around the plug.

Title: Pouring device having a built-in flow stopping mechanism
Inventor: DUMAS MARC
IPC: F16N37/00
Filed: 1994-07-05
Abstract: Abstract of the Disclosure:   A pouring device for pouring lubricating oil into the oil filler neck of a conventional engine. The pouring device is adapted to prevent unwanted spilling of oil onto the exterior surface of the engine block during the pouring operation. The pouring device has a cylindrical connecting neck portion which is adapted to be threadaly mounted over the discharge aperture of a conventional lubricating oil container. The connecting neck portion extends integrally into a spout. The spout has an inlet surface. A sealing membrane is hingely connected to the connecting neck portion, adjacent the inlet surface. The sealing membrane is adapted to pivot between a closed position wherein it prevents the lubricating oil from flowing through the inlet aperture and an open position wherein the sealing membrane allows the lubrificating oil to flow through the inlet aperture. The sealing membrane is adapted to be releasably locked in its close position by a locking lip which abuts against its peripheral edge. A biasing strip extends integrally from the sealing membrane. The biasing strip is adapted to create an initial biasing force which biases the sealing membrane against the locking lip. A trigger mechanism is attached to the biasing strip for selectively increasing the value of the initial biasing force to a level at which it will allow the sealing membrane to overcome the locking action of the locking lip on the sealing membrane and cause the sealing membrane to pivot into its open position. The trigger mechanism has a trigger lever which is adapted to abut against the exterior surface of the engine when the spout is pushed into the oil filler neck.

Title: Robust frequency management and acquisition in a wireless local area network that uses frequency-hopping radios
Inventor: FLEEK ARTHUR E
IPC: H04B1/7156
Filed: 1995-07-07
Abstract: A method for use in a single cell of a wireless communication system of the type having a leader station that coordinates communication among a plurality of remote stations that are in the cell. The method applies to systems that use slow frequency-hopping radios and a Carrier Sense Multiple Access (CSMA) type protocol. In this context, the method allows a remote station to initially acquire the frequency-hopping pattern and time base of the leader station and to maintain frequency synchronization in the face of control information loss due to radio transmission effects (e.g., interference, noise or multipath fading). In the acquisition phase, the remote station actively generates probe messages that are sent to the leader station so as to rapidly achieve frequency synchronization with the leader station.
