Title: Continuous platform cutting apparatus
Inventor: DENNEY DENYS
IPC: B26D3/28
Filed: 1998-07-22
Abstract: An apparatus for shaping a slab of compressible or cellular polymer material (80), such as polyurethane foam, by cutting portions of the material from one surface. A moving patterned platform (32), preferably an endless belt or a series of interconnected panels, is interposed between a compression roller (56) and a support surface (46) and defines at least one recess (36). When the slab is compressed between the compression roller and the platform, which is supported by the support surface, a portion of the material fills the recess or recesses in the moving platform. At least a portion of the compressed material within the recesses is then cut from the surface of the slab by a blade (76) just as the slab emerges from between the compression roller and the platform leaving a profile-cut surface with cut-out portions corresponding in pattern and shape to the recesses provided on the moving patterned platform.

Title: Mobile station communication network
Inventor: VALENTINE ERIC L
IPC: H04B7/15
Filed: 1997-09-16
Abstract: A mobile station communication network includes a high penetration network which schedules high transmission power level paging to reach a mobile station for which an acknowledgment signal is not received. A home location register stores mobile station high penetration network (HPN) subscriber feature information. The HPN analyzes mobile station class to determine an appropriate response when a mobile station fails to acknowledge a page request. The HPN  further maintains a record of short message service (SMS) time out (timer) values and examines the ID of the center that generated the message to determine when the SMS center will time out. Just prior to the time out, the HPN will send a "user unavailable" signal to the originating SMS center to avoid unnecessary paging request retries by the SMS center.

Patent CA-2282181-A1 (CA)
Title: Improved plowshare
Inventor: MESSINA FRANK DOMENICK
IPC: H02G1/10
Filed: 1999-09-10
Abstract: An improved plowshare is provided. Although it may be used in any submarine or terrestrial application requiring plowing or trenching, the improved plowshare is designed to be towed behind a cable-laying ship and to be used in underwater cable-burying operations to plow trenches in the ocean floor. The improved plowshare includes a downwardly-extending shank, a plurality of nozzles coupled to the shank, and a downwardly-swept protrusion for breaking up difficult soil and for controlling the depth of the shank in the soil as the trench is being plowed. The shank is rigid and capable of functioning as a passive plowshare, while the water jetting nozzles, which jet large volumes of water at a slightly forward angle relative to the perpendicular of the soil line, function as active trenching tools. The plowshare's use of both passive and active plowing technology allows it to be towed through the soil at a much lower drawbar force than traditional passive tools. Specifically, water from the nozzles fluidizes the soil in advance of the plowshare and creates a "swept volume flow" of fluidized soil that flows in a downward direction under and/or around the plowshare.  Fluidizing the soil in advance of the plowshare substantially reduces the drawbar force on the plowshare as it moves through the soil. To facilitate this flow of fluidized soil, the shank is aft-raked relative to the soil surface. Finally, the improved plowshare may be rotatable relative to the plow apparatus, thereby allowing it to function as a "rudder" for the plow apparatus.

Filed: 1999-10-21
Abstract: A push rod rotator and push rod boring rig uses a reciprocating carriage to push a drill string of push rods into the ground and pull the drill string back out usually with an expander and pipe or utility lines. A push rod rotator is connected to a swivel supported on the non-rotating carriage. The rotator is a two-part assembly, one part is a non-rotating conduit, having two or more helical slots and the other part has a pin which follows the slots for inducing relative rotation. Slips grip the: push rods and are reversible to enable push and pull operations. Preferably the slips trail the carriage and the rotator leads the swivel. The rotator is adapted to a boring rig having a frame, and hydraulic cylinders for reciprocating the carriage relative to the rig. The double-acting cylinders are mounted in pairs with the powerful extension stroke oriented to pull back the drill string and push rods and the weaker retraction stroke to push rods.

Filed: 1998-06-04
Abstract: Improved isoparaffin-olefin alkylation solid catalyst processes are provided which are characterized by low coke laydown and catalyst deactivation rates and production of valuable branched chain, high octane number alkylates. The processes of the invention involve providing a starting reactant mixture comprising an isoparaffin, an olefin and a co-solvent or diluent (carbon dioxide in molar excess, methane, hydrogen or mixtures thereof), and contacting the reactant mixture with an alkylation catalyst at near-critical or preferably supercritical conditions for the reaction mixture. The carbon dioxide serves as a co-solvent and reduces the critical temperature (Tc) of the reaction mixture, thereby allowing lower reaction temperatures. The isoparaffin and olefin reactants are preferably pretreated to minimize moisture, peroxide and oxygenate impurities therein.

Abstract: In a cellular mobile radio system, co-channel radio base stations are provided with a time reference signal being a synchronizing signal or a time reference from another co-channel radio base station. Each co-channel radio base station (708, 712) is also provided with a radio base station specific time offset (720, 722) differing between the co-channel radio base stations by at least a predetermined value which prevents known sequences in desired signals and known sequences in interfering signals from overlapping in a disturbing way at reception. In each co-channel radio base station the time reference signal and the radio base station specific offset are used for the timing of sending bursts downlink from the co-channel radio base stations towards mobile radio stations. Each radio base station has functions receiving the time reference signal, storing the time offset and using the time reference signal and the time offset for the timing of the burst termination on the downlink (720).

Title: A protective containment apparatus for potted electronic circuits
Inventor: LIPTAK JULIUS M
IPC: H02H9/04
Filed: 1999-04-23
Abstract: A protective containment apparatus for preventing damage to expensive components of an assembly due to the failure of an electronic component in a nearby potted circuit which is known to fail catastrophically. The containment apparatus can employ a resilient material placed around the at-risk electronic component prior to potting the circuit. The resilient material absorbs the expanding gases and fragmented parts of the at-risk component which are expelled during the catastrophic failure. The cushioning effect of the resilient material prevents the fragments and parts of the potting material from becoming projectiles that can damage any nearby components of the assembly.  The containment apparatus can also employ a restrictive material placed around the at-risk component prior to potting the circuit. The restrictive material prevents any expelled fragments of the at-risk component and expanding gases from causing the potting material to fracture and become projectiles which can damage nearby components of the assembly. A combination of the resilient material and the restrictive material can also be employed and is most effective in preventing damage to nearby component of the assembly.
