Title: Wastewater treatment process and apparatus
Inventor: MACLAREN DAVID S
IPC: C02F101/30
Filed: 1993-02-03
Granted: 2000-12-12
Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber (4), a biofilm-aeration chamber (7) and a settling chamber (16). Biofilm grows on the biofilm support structure (12), which is stationary and, submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestion process that conventional processes producing no sludge. Furthermore, the resulting treated effluent has a high dissolved oxygen content and low BOD and suspended solids.

Abstract: A thermally activated occlusive implant delivery assembly is provided.  The assembly includes an occlusive implant device and a pusher.  The pusher has a distal section and a proximal section.  The distal section includes a coupling portion which is shape memory material and exhibits different configurations depending on the coupling portion's temperature.  The coupling portion interlockingly engages the implant when it is in one of the configurations and releases the implant from interlocking engagement therewith when in another one of the configurations.  In operation, the assembly is introduced into the body of a mammal via a guide catheter suited for the particular lumen being navigated.  When the implant is positioned at the desired site, the coupling portion of the pusher is thermally activated to effect the return of its original, pre-set configuration, which is originally formed to release the implant from interlocking engagement therewith.  The pusher can then be readily removed from the mammal without imparting any significant force on the implant during retraction.

Abstract: A method and apparatus for forming a tensioned garter and bondingit to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surfce. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.

Title: Maintenance and administration of remote systems via radio pager
Inventor: CHAVEZ DAVID LEE JR
IPC: H04Q3/545
Filed: 1996-08-22
Granted: 2000-02-15
Abstract: An integral radio pager within each remote switch of a switching system with all pagers in the remote switches sharing the same paging service number with respect to a public paging service. When a central processor that is controlling the operation of all remote switches performs a maintenance restart operation with respect to one of the remote switches, the central processor requests that the public paging service page the common service number. The central processor also provides the paging service a paging message that defines which remote switch is to respond to the page. Each integral pager is responsive to the page to interrupt an associated remote processor. In turn, each remote processor is responsive to thepager to examine the paging message and only responds if the remote processor finds its own identification number in the paging message. In addition, the remote switches can each have an integral cellular telephone circuit that share a common telephone number thereby reducing the cost of providing the cellular telephone service. When the central processor wants to establish a data communication linkwith the remote switch via a cellular telephone call, the central processor requests that the public paging service page the common service number and provides a paging message to the public paging service. The paging message defines the identification number of the remote switch that is to respond to the page. A remote processor is responsive to the paging message to set up a data call via the integral cellular circuit to the central processor.

Granted: 2007-05-08
Abstract: An improved technique for determining the thickness of a member, especially pipe such as fluid-filled casing in an earth borehole, includes the following steps: directing a pulse of ultrasonic energy toward the inner surface of the pipe, and receiving and storing, as a function of time, signals representative of ultrasonic energy reflected from the inner surface of the pipe; determining, from the stored signals, the arrival time of the initial echo from the inner surface; determining, from the stored signals, thearrival time and the amplitude of a first candidate initial echo from the outer surface of the pipe; performing a reverse search on the stored signals to determine, from stored signals at times earlier than the arrival time of the first candidate, the arrival time and the amplitude of a second candidate initial echo from the outer surface; comparing amplitudes o f the first and second candidates, and selecting, based on the comparison, one of the first and second candidates as the actual outer surface echo; and determining the thickness of the pipe from the arrival time of the actual outer surface echo and the arrival time of th e inner surface echo. Using this technique, the earlier arriving candidate can be properly identified as the actual outer surface echo, evenw hen the later arriving candidate has a greater amplitude.
