Title: Electrostatic spray gun
IPC: B05B5/025
Filed: 1988-02-24
Abstract: The nozzle assembly of an electrostatic spray gun has an adapter which is made of an electrically insulating material and has a front surface facing in the direction of propagation of material issuing from the orifice of the nozzle. The adapter has a frustoconical extension which surrounds the orifice and whose external surface defines with the front surface of the adapter an annular space for the tips of electrodes which ionize air flowing toward the spray of material that issues from the orifice. The locations of the tips of electrodes (preferably very close to the front surface of the adapter) and the inclination of the external surface of the frustoconical extension determine the location of contact of ionized air with the spray. The tips of the electrodes are shielded from mechanical damage by being located in the annular space.

Title: System for the extended provision of cellular mobile radiotelephone service
IPC: H04W8/26
Filed: 1989-09-19
Abstract: A technique for enabling a Roaming Cellular 
Mobile Radiotelephone (CMR) subscriber to 
automatically receive, in a foreign service area calls 
placed to his mobile identification number 
(MID) at his home service area. An FMR ("Follow-Me-Roam") 
processor is coupled through a cable or LAN to a 
switch associated with the foreign MTSO and is 
coupled, preferably through a private data network, to 
a switch associated with the subscriber's home MTSO. 
Within the FMR processor resides a program that detects the 
reception at the foreign switch of a predetermined 
code indicating that calls placed to the roamer's home 
MID are to be forwarded to the foreign MTSO. 
Subsequent to the "validation" of the roamer and to 
the performance of certain software housekeeping 
tasks, the roamer is assigned a Temporary Directory 
Number (TDN) for use in the remote service area. The 
FMR processor then commands the subscriber's home MTSO 
switch to forward calls, placed to the subscriber's 
MID at the home MTSO, to the TDN. Calls are 
subsequently forwarded, via the PSTN, from the 
subscriber's home MTSO to the foreign MTSO.
