Patent CA-2364348-A1 (CA)
Inventor: WENZEL WILLIAM RAY
IPC: E21B21/10
Filed: 2001-12-03
Abstract: A mudsaver valve with retrievable inner sleeve. An annular piston is secured to a first end of the inner sleeve such that movement of the annular piston results in movement of the inner sleeve between a valve closed position and a valve open position. In the valve closed position radial outlet passages of the inner sleeve are blocked by a flow control sleeve. In the valve open position the inner sleeve is moved relative to the flow control sleeve so that the radial outlet passages are no longer blocked. The inner sleeve is maintained in the valve closed position until pump pressure acting upon the annular piston overcomes a biasing force of a biasing spring causing the inner sleeve to be carried by the annular piston to the valve open position.

Title: Models of prion disease
Inventor: PRUSINER STANLEY B
IPC: G01N33/68
Filed: 2000-05-24
Abstract: The present invention provides a novel PrP protein, and nucleic acids encoding this protein, where the PrP protein is characterized <i>in vivo</i> by 1) incomplete glycosylation relative to glycosylation of wild-type Prpc and 2) proper cellular localization, i.e. an ability to be transported to the cell surface. This novel, under-glycosylated PrP, unlike its normal cellular counterpart, can easily be converted into a protease-resistant isoform by incubation with infectious prions. The invention further provides systems for the study of prion disorders and methods of using these systems, <i>e.g.</i>  the study of the mechanical processes in progression of prion-mediated disease or the identification of new therapeutic agents for treatment of prion-mediated disorders. In such systems, protease-resistant under-glycosylated PrP  is generated <i>de novo</i> and can be detected by standard immunoblot techniques.

Title: Scrubber for removing hydrogen sulphide from natural gas stream
Inventor: LONGMIRE ANDREW J
IPC: B01D53/14
Filed: 2002-05-06
Abstract: The present invention is concerned with a scrubber for removing hydroge n sulphide (H2S) from natural gas using an H2S-scavenging solution. The scrubb er comprises an upright cylindrical vessel forming a closed chamber, the vessel having a product outlet at its upper end. A gas feed pipe, extending centrally and longitudinally of the chamber from the upper end of the vessel, delivers gas to the base of the chamber through an outlet formed by the pipe. The feed pipe supports a stack of vertically spaced apart, conical perforated plates that extend radially from the feed pipe to form a narrow annular gap with the sidewall of the vessel. The feed pipe supports a conical imperforate plate located above the outlet and below the stack of perforated plates. Gas entering the vessel through the feed pipe outlet is guided outward by the imperforate plate to be distributed throughout a body of H2S- scavenging solution. The perforated plates act to contain the rising gas and break down large bubbles into fine gas bubbles. Scavenger solution carried upward by the gas returns to the bottom of the vessel by passing through the annular gap.< /SDOAB>

Inventor: SMITH A MURRAY
IPC: G06Q10/10
Filed: 2002-07-19
Abstract: An organization can manage its compliance through a system and process for collecting characteristic data for regulated elements and applying a rule application system to identify those having an out-of compliance status. A responsible representative is assigned and notified of the out-of compliance status and compelled to perform corrective actions through repeated and successive notification of the assigned representative and a hierarchy of responsible representatives until compliance is achieved. Compliance is further compelled through assigning a default out-of-compliance status for an element until such time as its characteristics are collected such as through mandatory data collection.~ Preferably, the compliance management system is implemented in a client-server network utilizing remote data collection devices and server-based applications and databases of rules, a corrective action register of pending out-of compliance elements and a compliance calendar interface for responsible representatives.
