Publication number: 20090266754Abstract: A method of manufacturing a cast article including a frame that in use of the article defines an aperture; and a further component that is in use retained moveably captive relative to the frame. The method casts the further component and respective first and second frame members, the further component and the frame members being securable together to form the article, and subsequently assembles the frame members and the further component together to form the article. A gully grate results from practicing the method.Type: ApplicationFiled: December 19, 2005Publication date: October 29, 2009Applicant: Saint-Gobain PamInventors: Alan Jack Pendleton, Keith Stanley Thompson, John Neil Pickavance, Steven Peter Baldwin

Publication number: 20090211579Abstract: A method of conveying humid breathing gases from a patient through a breathable breathing tube. The breathing tube includes a heater associated, at least in part, with a portion of hydrophilic material. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked tip by the hydrophilic material. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.Type: ApplicationFiled: May 6, 2009Publication date: August 27, 2009Inventors: Daniel John SMITH, David Peter BALDWIN

Patent number: 7559324Abstract: A conduit for a breathing circuit includes a heater associated, at least in part, with a portion of hydrophilic material. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic material. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.Type: GrantFiled: August 27, 2003Date of Patent: July 14, 2009Assignee: Fisher & Paykel Healthcare LimitedInventors: Daniel John Smith, David Peter Baldwin

Publication number: 20090078260Abstract: A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapour without allowing the passage of liquid water or respiratory gases. The breathing circuit component is the expiratory limb of a breathing circuit.Type: ApplicationFiled: December 4, 2008Publication date: March 26, 2009Inventors: DANIEL JOHN SMITH, GAVIN WALSH MILLAR, KEVIN BLAKE POWELL, DAVID PETER BALDWIN

Publication number: 20070027887Abstract: A fully web-enabled method for diagrammatically representing the meaningful structure of a complex argument or debate, or other similar information, as a schematic map made up of nodes each of which represent a discrete element in said meaningful structure comprising the steps of: (a) Beginning a new map by specifying the broad subject matter and other data about said map and selecting from one of a plurality of sets of encoded information and rules, termed Map Grammars, that constrain how nodes of different types may be combined to form maps and the actions available to persons building, editing or otherwise interacting with such maps. (b) Associating selected information items relevant to said argument or debate, or other information, with map nodes. (c) Adding nodes to said schematic map in such a way as to form an overall structure in which nodes are organized so as to conform to said Map Grammar at all times.Type: ApplicationFiled: October 5, 2006Publication date: February 1, 2007Inventor: Peter Baldwin

Patent number: 7157035Abstract: The present invention relates to delivery conduits used in systems that provide positive pressure ventilation therapy. In particular, the present invention relates to a sleeve that allows flexible conduits to be joined and sealed to a thermoplastic connector, allowing for gases to be supplied to the conduit. The sleeve is used in the over moulding of an end connector onto the conduit. The sleeve and method of attaching a connector to a conduit of the present invention has the advantage that it prevents the connector from loosening or breaking when the conduit is bent, pulled or stressed, which can occur in some cases where the connector is attached to the conduit using a bond, such as glue. Furthermore, the occurrences of flashing of plastic across the conduit walls will be prevented during moulding, ensuring that no air or water leakages occur within the conduit walls.Type: GrantFiled: December 9, 2002Date of Patent: January 2, 2007Assignee: Fisher & Paykel Healthcare LimitedInventors: Deshitha Airawana Edirisuriya, David Peter Baldwin

Patent number: 4873618Abstract: A power supply for an arc lamp. It includes a DC to DC converter which has an input, an output, and a circuit for increasing the voltage received at the input and for supplying the increased voltage to its output. A current sensing circuit is provided for controlling the amount of current delivered to the output. The power supply is capable of quickly igniting and re-igniting arc lamps, is relatively inexpensive to manufacture and is relatively light in weight. The power supply can accept either an AC or DC source over a wide voltage range and increases or decreases the input voltage compared to the output voltage.Type: GrantFiled: December 3, 1987Date of Patent: October 10, 1989Assignee: Camera Platforms International, Inc.Inventors: William Fredrick, Robert Brent, Peter Baldwin

It includes a DC converter which has an input, an output, and a circuit for increasing the voltage received at the input and for supplying the increased voltage to its output. A current sensing circuit is provided for controlling the amount of current delivered to the output. An output "H" bridge is coupled to the output of the DC converter for generating a squarewave in response thereto. The power supply is capable of quickly igniting and re-igniting arc lamps, is relatively inexpensive to manufacture and is relatively light in weight. The power supply can accept either an AC or DC source over a wide voltage range and increases or decreases the input voltage compared to the output voltage.Type: GrantFiled: May 21, 1987Date of Patent: October 10, 1989Assignee: Camera Platforms International, Inc.Inventors: William Fredrick, Robert Brent, Peter Baldwin
