Title: System and method for establishing communications with a mobile party
Inventor: FOLADARE MARK JEFFREY
IPC: H04M11/02
Filed: 1996-01-02
Abstract: A communication system capable of establishing communications between a calling party and a mobile called party that is equipped with a  two way pager.  The calling party initiates an incoming call by dialing the called party's Personal Telephone Number.  The call is coupled to an adjunct which holds the call while contacting the mobile party.  The adjunct contacts the mobile party by cross referencing the dialed Personal Telephone Number to a pager code for the called party and  then initiating the transmission of a paging signal.  The paging signal alerts the called party to the incoming call at which time the called party responds by sending a return signal to the adjunct via the two way pager.  The return signal includes a forwarding number corresponding to a communication device to which the adjunct directs the incoming call.

Title: Exhaust gas diffuser interface
Inventor: SCHOCKEMOEHL GENE F
IPC: F02K1/82
Filed: 1996-09-04
Abstract: An improved exhaust gas diffuser interface includes a stainless steel shell with varying levels of insulation. The varying levels of insulation concentrate thermal expansion and contraction at the turbine outlet end allowing it to be connected to the outlet by way of a seal weld. This construction allows expansion and contraction of the diffuser interface in unison with the attached turbine outlet, as well as the diffuser inlet.

Title: Cam operated timer motor
Inventor: AMONETT DANIEL KEITH
IPC: H02K3/00
Filed: 1997-05-28
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.
