Title: Wide area paging system having automatic service area log-in
Inventor: DAVIS WALTER L
IPC: H04W84/02
Filed: 1994-12-15
Abstract: A combination pager and cordless telephone (40) has a receiver (414) for receiving paging signals including a location identifier associated with a geographic location (202) of a paging controller transmitting the paging signals. A decoder (416) coupled to the receiver (414) decodes the paging signals to recover a page and the location identifier. A memory (422, 423) stores the page and the location identifier identifying the geographic location (202) of the transceiver (40). A message processor (606), coupled to the memory (423), determines when a new location identifier is received; and a controller (420) couples to a home paging controller (10) in response to the message processor (606) determining that the new location identifier has been received. A transmitter (440), coupled to the controller (420, 430), transmits the new location identifier to the home paging controller (10) for informing the home paging controller (10) that the transceiver (40) is located in the new geographic location (210) indicated by the location identifier.

A process controller (13) positions the sleeve (28) by means of a pair of screw jacks (54). The controller (13) adjusts the discharge gap (26) width to maintain feed material temperature within a predetermined band. Alternately the controller (13) adjusts the discharge gap (26) width and feed screw (18) speed to maintain a predetermined specific energy input into the feed material. The helical screw (18) is preferably supported at both ends by a bearing means (42, 60). Breaker bars (46) are mounted on the transverse plate (24) and extend over the gap (26) between the discharge opening and the plate (24). Breaker bars (80) may also be mounted to the cylindrical sleeve (28) and extend over the gap (26) between the sleeve (28) and the plate (24).

Title: Methods of making preloaded ball nut and screw assemblies and the products formed thereby
Inventor: BENTON ROBERT L
IPC: F16H25/22
Filed: 1995-01-24
Abstract: A method of making ball screw and nut assemblies, and the products which result, wherein the nut is provided with a deformable wall portion of decreased compressive strength interjacent the ends of the nut.  A compressive force is applied to the nut to axially deform the portion of decreased compressive strength while not changing the lead of adjacent lands and grooves in the non-compressed portion of the nut.  The axial position of the lands and grooves in the non-compressed portion is thereby axially displaced such as to preload a recirculating train of balls traveling along the non-compressed portion of the nut relative to the lands and grooves of the screw, when the screw, nut, and balls are assembled.
