Title: Timing recovery in digital data communications
Inventor: CAPKUN EDWARD ANTHONY
IPC: H04L7/04
Filed: 1991-05-29
Abstract: In apparatus for receiving digital data signals in a digital communication system, especially an Integrated Services Digital Network, timing recovery problems associated with erratic zero crossing when multiple terminals transmit to a common receiver are mitigated by detecting the rate of change of the digital data signal between two predetermined positions and controlling sampling of the digital data signal in dependence upon the difference between such rate of change and a reference. The rate of change conveniently corresponds to the trailing "corner" of a framing pulse, i.e. the point at which the signal commences the transition from one polarity to the other. The "corner" is much more stable, i.e. less susceptible to variation due to multiple terminal effects, than the zero-crossing which follows it, since the zero crossing may vary relative to the "corner". The transition may be determined by sampling the digital data signal at two discrete positions and determining when the two resulting samples differ in amplitude by a predetermined amount. One of the two pulses, namely the one with the larger amplitude, may then be used for data recovery purposes.

Patent NZ-239824-A (NZ)
Title: Production of lactide
Inventor: SINCLAIR RICHARD G
IPC: C08L67/04
Filed: 1991-09-17
Abstract: The present invention is directed to a method for making L-lactide from aqueous L-lactic acid. Aqueous lactic acid feed for present purposes comprehends an aqueous mixture of one or more of L1A, L2A, and L3A, optionally with LD being present. L-lactic acid is the preferred feed configuration for making L-lactide, and is to be understood even though the configuration symbol is not used throughout this application. Aqueous lactic acid feed is treated for removal of water therefrom until a degree of polymerization (DP) not substantially above about 2 is reached. The treatment then is ceased to produce a crude LD product. LD then is separated from the crude LD product. A preferred treatment involves heating the feed at elevated temperature to remove water. LD can be separated from the crude LD product by a variety of techniques to produce an LD-depleted product. This LD-depleted product, optionally augmented with additional aqueous lactic acid and/or water then can be readmitted to the process for making additional lactide. This cyclic or recycle process embodiment of the present invention enables very high lactide conversions to be realized.

Patent NZ-240526-A (NZ)
Title: Catheter connector: carries sensor in fluid passage
Inventor: RING WALLACE H
IPC: A61B5/0215
Filed: 1991-11-08
Abstract: A connector (10) carrying a sensor (11) for placement in a catheter adapter (12) has proximal and distal parts with a passage therebetween. The distal part (16) detachably fits within a catheter adapter. The connector, when attached to the adapter, places the passage (A) in fluid communication with and near a catheter lumen. A sensor on the connector within the distal part is exposed to the passage for fluid communication with the lumen. The sensor mounts on a tube (20) or in an inside wall of the distal part and extends within the passage and partially through the distal part to monitor pressure with a first side (21) of the sensor exposed to the passage and a second side (22) of the sensor covering an exit from the connector near the proximal part. The second side is vented to atmospheric pressure and a sensor signal communication means connects the sensor to pass signals from the sensor through the exit. A sleeve (30) extends distally on the connector for threaded engagement with a male luer on the adapter allowing fluid tight communication between a cavity within the adapter and the passage. The distal part substantially fills the cavity reducing the hydraulic column volume in the lumen and the passage. A method places a catheter into a human or animal to provide access to dynamic pressure, measures atmospheric pressure with a sensor carried on a connector, sets the signal response of the sensor measurement to a datum for atmospheric pressure applied to first and second sides and attaches the connector to the adapter to fit the distal part into the cavity in the adapter so gas within the cavity and the passage escapes to provide a hydraulic column substantially free of gas. <IMAGE>

Patent NZ-516691-A (NZ)
Title: Phosphate mineral-based reactive barrier containment system
Inventor: EIGHMY T TAYLOR
IPC: G21F9/30
Filed: 2000-07-13
Abstract: A phosphate mineral based reactive barrier system. Phosphate minerals are known to be sinks for heavy metal contaminants. The reactive barrier prevents the release of contaminants from waste materials, sediments or dredged materials via reaction with the contaminants at the interface between the barrier and the waste material, sediments or dredged material. The barrier is comprised of a phosphate mineral material where the form of the phosphate mineral is variable but primarily insoluble. This barrier is placed below, around, and/or on top of the contaminated materials such that the contaminated materials are completely enveloped, capped, or contained by a grout curtain. The barrier can be in a (i) slurry form, (ii) blended matrix form with other inorganic agents, or (iii) composite form with a geotextile or geofabric. These methods of construction can be used singly or jointly. In some cases, pH control may be used to optimize the chemical reactions within the barrier system. The barrier mechanism relies on the phenomena of adsorption, surface precipitation and co-precipitation of metal phosphate surface precipitates to chemically retard diffusion from the waste material. Immobilization may also occur secondarily when a small percentage of the phosphate minerals partially dissolve and the phosphate precipitates with metals to form metal phosphate precipitates in the pore water system of the reactive barrier. The contaminated wastes, sediments or dredged materials may have been subjected to solidification or chemical stabilization or other forms of treatment prior to disposal

Abstract: An apparatus and method is disclosed for perforating and treating multiple intervals of one or more subterranean formations (86) intersected by a wellbore by deploying a bottom-hole assembly having a perforating device (134) and at least one sealing mechanism (120) within the wellbore. The perforating device (134) is used to perforate the first interval to be treated. Then the bottom-hole assembly is positioned within the wellbore such that the sealing mechanism (120), when actuated, establishes a hydraulic seal in the wellbore to positively force fluid to enter the perforations (230, 231) corresponding to the first interval to be treated. A treating fluid is then pumped down the wellbore and into the perforations (230, 231) created in the perforated interval. The sealing mechanism (120) is released, and the steps are then repeated for as many intervals as desired, without removing the bottom hole assembly from said wellbore.
