Abstract: A method of and apparatus for paging a wireless terminal in a wireless telecommunications system reduce standby mode power consumption. A minimally encoded quick paging channel is established over which short, quick page messages are transmitted during one of a set of quick paging slots. The quick page message indicates that a communications request has been received, and that the receiving communication terminals should process a highly encoded full paging channel over which more detailed, full page messages are transmitted during the next full paging slot. A terminal monitors full paging channel only after a quick page message has been received on the quick paging channel.

Title: Process for producing propylene and hexene from c4 olefin streams
Inventor: JONES QUINCY J
IPC: C07C6/04
Filed: 2003-03-07
Granted: 2008-09-09
Abstract: A C3 to C6 hydrogen cut from a cracking unit is processed for the conversion of olefins to propylene and hexene via autometathesis. The autometathesis of a mixed normal butenes feed in the presence of a metathesis catalyst operates without any ethylene in the feed mix to the metathesis reactor. Some fractio n of the 2-butene feed may be isomerized to 1-butene and the 1-butene formed plus the 1-butene in the feed react rapidly with the 2-butene to form propylene and 2-pentene. The feed to the reactor also includes the recycle o f the 2-pentene formed in the reactor with unreacted butenes to simultaneously form additional propylene and hexene. In one embodiment, some or all of the 3- hexene formed in the reaction is isomerized to 1-hexene. In another embodiment, some portion of the 3-hexene produced in the main metathesis reaction is reacted with ethylene to produce 1-butene without the need for superfractionation. In another embodiment, the 3-hexene product is hydrogenated and recycled back to the cracking heaters.

Abstract: An assembly technique for closing a movable socket (10) without the need to deform or displace any portion of the socket housing (12), thereby allowing for the use of fully hardened socket housing materials. The internal components of the movable socket are installed within the housing through an opening (16), and a conical cover-plate (66) is positioned over the components, within the opening. An assembly tool (100) configured to exert pressure on the conical cover-plate is brought into engagement with the plate, and a downward load is applied, expanding the plate to seat within a circumferential groove (22) in the housing. The assembly tool includes a specifically contoured face (109) which alters the angle at which pressure is exerted against the expanding conical cover-plate as the plate deforms to a generally planar configuration, closing the opening in the housing. Once expanded, the cover-plate seats within the groove formed in the interior surface of the housing, thereby securing the internal components within the housing.

Title: Method for improved vertical sweep of oil reservoirs
Inventor: STONE HERBERT L
IPC: E21B43/16
Filed: 2004-05-10
Granted: 2008-08-05
Abstract: In a WAG flood oil is displaced from a subterranean formation by injecting water alternately with gas into a single injection completion per pattern. The ratio of water to gas injected is the WAG ratio. In this invention, two separate injection completions (14, 16) are used in each pattern, with one placed directly above the other. A very low WAG ratio is used for injection into the bottom extremity of the formation. A very high WAG ratio is injected into the upper interval, at as high a rate can safely be used without fracturing the formation. In the preferred embodiment, two horizontal well bores (14, 16) serve as the two completion intervals. Proper design of this method gives a vertical sweep efficiency of the gas that is several-fold greater than the best of previous WAG flood designs, especially in thin formations.
