Publication number: 20080308102Abstract: A manifold for use in a medicament dispenser device for the delivery of medicament powder from an open blister pocket of a blister pack comprises a body, the body defining a chimney having a chimney inlet and a chimney exit for directing airflow from said chimney inlet to the chimney exit; the body further defining a chamber having a chamber inlet and a chamber exit, wherein the chimney exit and the chamber inlet lie side-by-side each other such that when the open blister pocket of the blister pack is positioned adjacent thereto the airflow is directed from the chimney exit to the chamber inlet via the open blister pocket to entrain the medicament powder and enable transport thereof in the airflow from the chamber inlet to the chamber exit, and wherein one or more bleed holes are provided between the chimney and the chamber such that bleed airflow is able to be directed into the chamber to disruptively impact the airflow that transports the entrained medicament powder.Type: ApplicationFiled: December 11, 2006Publication date: December 18, 2008Inventors: Michael Birsha Davies, Mark Andrew Hailey, Mark Gregory Palmer, Richard Ian Walker

Patent number: 7438922Abstract: Combinations of cell lines are provided for allogeneic immunotherapy agents in the treatment of cancer. Cancer vaccines generally have been limited to the use of cells that contain at least some tumor specific antigens (“TSAs”) and/or tumor associated antigens (“TAAs”) having shared identity with antigens in a targeted tumor. In such cases, tumor cells often are utilized as a starting point on the premise that only tumor cells will contain TSAs or TAAs or relevance, and the tissue origins of the cells are matched to the tumor site in patients. A primary aspect of the invention is the use of immortalized normal, non-malignant cells, in combination with primary and/or metastatic tumor cells, as the basis of an allogeneic cell cancer vaccine. Normal cells do not posses TSAs or relevant concentrations of TAAs and hence it is surprising that normal cells are effective as anti-cancer vaccines when administered in combination with primary and/or metastatic tumor cells.Type: GrantFiled: July 23, 2004Date of Patent: October 21, 2008Assignee: Onyvax LimitedInventors: Angus George Dalgleish, Anthony Ian Walker

Patent number: 6972128Abstract: The invention here relates to a product comprised of a cell line or lines intended for use as an allogeneic immunotherapy agent for the treatment of cancer in mammals and humans. All of the studies of cell-based cancer vaccines to date have one feature in common, namely the intention to use cells that contain at least some TSAs and/or TAAs that are shared with the antigens present in patients' tumour. In each case, tumour cells are utilised as the starting point on the premise that only tumour cells will contain TSAs or TAAs of relevance, and the tissue origins of the cells are matched to the tumour site in patients. A primary aspect of the invention is the use of immortalised normal, non-malignant cells as the basis of an allogeneic cell cancer vaccine. Normal cells do not possess TSAs or relevant concentrations of TAAs and hence it is surprising that normal cells are effective as anti-cancer vaccines.Type: GrantFiled: December 9, 1999Date of Patent: December 6, 2005Assignee: Onyvax LimitedInventors: Angus George Dalgleish, Peter Michael Smith, Andrew Derek Sutton, Anthony Ian Walker

Patent number: 6929773Abstract: A method of determining disturbances when discharging molten metal from a metallurgical container having an outlet into a receiving container. In steps of this process, a real time video image of the teeming stream is monitored to detect the presence of a slag phase, or conditions conducive to the presence of such a phase in steel being transferred, the monitored images are processed to provide data used to assess the quantity of slag passed, parameters of data generated representing characteristics of the teeming stream image are compared with threshold values to generate at least one signal indicative of the passage of slag, and the threshold values are progressively adjusted responsive to data collected by monitoring plural parameters of the teeming operation selected from predicted teeming duration, weight of the receiving vessel, condition of means controlling teeming rate, and oxygen content of the molten steel.Type: GrantFiled: April 5, 2004Date of Patent: August 16, 2005Inventors: Frank L. Kemeny, David Ian Walker
