Title: Fluid dispense and liquid surface verification system and method
Inventor: LIPSCOMB JAMES
IPC: G01N35/08
Filed: 2001-02-28
Granted: 2011-02-22
Abstract: A sensor for detecting contact of a fluid delivery probe with a fluid surface and for detecting fluid flow through the probe includes a first electrode disposed along a fluid flow path of the probe upstream from a distal tip of the probe and a second electrode longitudinally spaced and electrically isolated from the first electrode and disposed at the distal tip of the probe. An oscillating signal is transmitted through the first electrode, and at least a portion of the signal is received through the second electrode. Through changes in the received signal due to the distal tip of the probe coming into contact with a fluid surface or due to fluid flow through the conduit between the first and second electrodes, fluid surface contact and fluid flow can be detected. A pressure sensor can be employed to monitor intemal fluid pressure within the fluid conduit of the fluid delivery probe as a secondary, redundant means for detecting fluid flow through the conduit.

Title: Verifiable, secret shuffles of encrypted data, such as elgamal encrypteddata for secure multi-authority elections
Inventor: NEFF C ANDREW
IPC: G06Q50/00
Filed: 2001-03-24
Granted: 2006-05-23
Abstract: A cryptographic process permits one to verifiably shuffle a series of input data elements. One or more authorities or individuals "shuffle", or "anonymize" the input data (e.g. public keys in discrete log form or ElGamal encrypted ballot data). The process includes a validity construction that prevents any one or more of th e authorities or individuals from making any changes to the original data without being discovered by anyone auditing a resulting proof transcipt. The shuffling may be performed at various times. In the election example, the shuffling may be performed, e.g., after ballots are collected or during the registration, or ballot request phase of the election, thereby anonymizing the identities of the voters.

Abstract: A process for separating an aqueous emulsion including an aqueous phase and an non-aqueous phase into separated aqueous and non-aqueous phases, to provide a recovered non-aqueous phase, and to provide a recovered aqueous phase containing an acceptable level of the non-aqueous phase. In the process, at least one body, and preferably two or more bodies, of polymeric material with a high surface area, typically a foam material or polymer chips, is used in a horizontal flow treatment system to break the emulsion and thus provide both the aqueous and non-aqueous phases as two separate flows. A wide range of polymers can be used in the system as the polymeric material including polyurethane, polypropylene, polystyrene, polyester, and polyethylene. If a very low level of non-aqueous phase in the effluent is required, for example to meet potable water standards, then a Kozlowski polyurethane, as described in US 5,239,040, is preferred as the last polymeric material body.

Abstract: Oil sands are flooded and then dredge mined via barges. The mined ore and water form a slurry which is pumped to a floating plant where the slurry may be processed, or the bitumen may be extracted. The process ensures the oil sands do not freeze, making excavation easier during the winter months, and reducing slowdowns due to frost lumps. The process also eliminates the need to use shovels and trucks in the mining pits, resulting in an overall reduction in costs and a reduction in carbon dioxide emissions.

Title: Sliding sleeve valve
Inventor: KASZUBA FRANK
IPC: E21B34/14
Filed: 2003-07-31
Granted: 2007-02-20
Abstract: A sliding sleeve valve and method for assembly is disclosed. The valve comprises a segmented main body that is assembled from a top, middle and bottom segments. The middle segment has flow apertures. A closing sleeve is co-axially mounted in the assembled main body. The closing sleeve has flow apertures that are intended to communicate with the flow apertures of the middle section when the valve is open. The closing sleeve is sealed by seal means within the main body to prevent undesired fluid flow across the valve. The seal means comprise primary, secondary and tertiary seals acting in cooperative combinations. The seals comprise O-Ring and Vee-stack seals located within the body of the valve. The sliding sleeve valve has a fluid pressure equalization means to permit equalization of fluid pressure across the valve before it is fully opened or fully closed in order to reduce wear on the seals. The equalization means comprises a plurality of pressure equalization ports in the sliding sleeve that are intended to communicate with the main body apertures prior to the sliding sleeve apertures when opening and subsequent to the sliding sleeve apertures when closing.
