Title: Electrical receptacle with safety shutter
Inventor: MEHTA PARAG J
IPC: H01R13/453
Filed: 1997-04-21
Abstract: An electrical receptacle of the type having movable shutter members positioned to prevent insertion of objects other than electric plugs through the plug blade-receiving openings into contact with line terminals.  Two identical shutter members, each having a camming portion and a blocking portion, are mutually assembled for relative, linear movement in either of two, opposite directions from a centered position to which they are biased by a pair of coil springs.  Rigid objects inserted through the receptacle openings contact an angularly disposed surface on the camming portion of the shutter members, causing lateral movement of the element.  When the blades of a plug are inserted, both shutter members move laterally to permit continued advance of the blades into the terminal contacts.  When a single object is inserted, the blocking portion of one shutter element prevents advance of the object.  A lip on the blocking portion prevents passage of the inserted object around the shutter element.  Other features include compatibility of the shutter structure with existing receptacles, including those with straight straps, a one-piece spacer supporting the shutter elements for low-friction movement and ease of automated assembly.

Title: Method of synchronizing satellite switched cdma communication system
Inventor: GERAKOULIS DIAKOUMIS PARISSIS
IPC: H04B7/216
Filed: 1997-04-23
Abstract: The present invention relates to a method of synchronizing CDMA processing in a satellite communication system connecting multi-point ground stations. The method is comprised of the steps of acquiring access and synchronization signals transmitted by a satellite at a terrestrial subscriber unit, setting a reference propagation delay time, and establishing a propagation delay in terms of arrival of a message in relation to one of a plurality of quantified timing marks subsequent to the reference propagation delay time, when the satellite receives a first signal from the terrestrial subscriber unit on an access channel. The method further comprises the steps of conveying the established quantified propagation delay to the terrestrial subscriber unit, adjusting timing of uplink CDMA code chips at the terrestrial subscriber unit from the original reference propagation delay derived from the access channel, tracking synchronizing by adjusting code delay of the uplink arrival time of a reference code, and retaining synchronization by downlink code delay transmission.

Title: Personal telephone agent
Inventor: PAPAVERO ELENA MARIA
IPC: H04M3/50
Filed: 1997-06-18
Abstract: A personal telephone messaging agent can automate routine scheduling, coordinating and information gathering tasks while maintaining the advantages inherent in the telephone system.  A person specifies a message and, optionally, some specific questions, and a list of recipients to his or her personal messaging agent.  The messaging agent delivers the message to and collects a response from each messaging recipient using the telephone system.  When each intended recipient has been reached, the agent contacts the sender to report the results or, optionally, the agent could undertake routine tasks such as scheduling a meeting based upon the responses and assigning a conference room for the meeting.    An even more sophisticated personal telephone agent may be employed in the context of an information retrieval service.  An IVR system has an interface designed for people to use.  However, the databases of information that an IVR system draws upon could be accessed over the telephone network by an automated agent using an interface designed for agent access.  In this way, a messaging agent can be used to retrieve the desired information and report back to the caller. The personal telephone messaging system of the present invention can be applied to tasks such as scheduling a meeting, confirming a decision, determining the price of an item, and finding flight information.

Patent CA-2214232-A1 (CA)
Title: Variable rotary engine
Inventor: LINNEL JEAN
IPC: F02B53/00
Filed: 1997-08-27
Abstract: A rotary engine contains a laterally displaceable rotary member which is sealably and slidably engaged by a rotor plate which has been modified for sealing, travels in an eccentric circle along with the rotor, but provides sealing against the rotor using corner seals and surface seals, and is also further sealed against the engine housing so that combustion gasses in the vicinity of the rotor and rotor plate do not escape either between the rotor and rotor plate surfaces nor between the rotor plate surfaces and the engine housing surfaces.  The other end of the rotor rotatably depends from a reducing piston which is sealably engaged against the internal portion of the engine so that it can travel laterally, in order to laterally displace the rotor.  During engine operation, the rotor can be made to be axially displaced or pushed through the rotor plate to lower the effective combustion volume. The reducing piston is physically manipulated from outside of the engine by actuation of a plurality of push-pull rods which connect the reducing piston ultimately to an actuator.   An actuator is used to operate the push-pull plate and a sensor can be utilized to measure the displacement of the push-pull rods and plate to better control the resulting engine displacement.
