Publication number: 20080121365Abstract: Techniques for forming cast parts for medical devices suitable for contact with internal regions of patients are described herein. Such parts can be small in scale (e.g., having a major axis less than 0.3 inches, and/or a minor axis less than about 0.08 inches), and can be formed from metals that have a high melting point and high reactivity with environmental components or mold surfaces, such as stainless steel and titanium alloys. Such techniques can include injecting molten metal into the sprue of a mold tree such that the side runners are backfilled after the molten metal impacts a closed end of the sprue. Side runners can be oriented in particular directions and positions to promote backfilling. As well, flask temperatures and the use of surfactants can also promote cast part formation, hindering the formation of surface defects.Type: ApplicationFiled: December 3, 2007Publication date: May 29, 2008Applicant: ETHICON ENDO-SURGERY, INC.Inventors: William A. Crawford, Tracy J. Potter, Donald F. Heaney, Brian S. DeForce, Samardh Onukuri

Publication number: 20080017229Abstract: A prefabricated shell for forming a shelter (14) has a groundsheet (30) and a cover (32) having a gas impermeable inner layer (24) and at least one outer layer. The outer layers are each formed by a layer of cloth that has been impregnated with a water-settable material, e.g. cement. The shell is steeped in water to wet the cement and then the cover is pneumatically inflated to form a space between the cover and the groundsheet. The shelter is then left until the cement has set and is able to support the cover. The shelter can easily be constructed to provide a durable shelter, especially in emergency areas.Type: ApplicationFiled: June 17, 2005Publication date: January 24, 2008Applicant: CRAWFORD BREWIN LTDInventors: Peter Brewin, William Crawford

Publication number: 20070118893Abstract: Firewalls and other filtering gateways have become common security devices for improving computer network security. As more features and functionality are added to these devices they become quite complex to configure. By associating configuration schemes with firewall policies, configuration can be simplified without compromising flexibility. Administrators have more options to filter different traffic streams based on their type and sources. They also have increased flexibility to be able to filter traffic on a per user basis, through authentication mechanisms tied to various filtering options.Type: ApplicationFiled: November 22, 2005Publication date: May 24, 2007Inventor: William Crawford

Publication number: 20060225771Abstract: A method and apparatus for cleaning accumulated silt from the floor of a percolation basin are provided. An underwater terrain vehicle (UTV) moves along the basin floor and carries a series of blades that cut and lift the accumulated silt. An eductor driven vacuum head also carried by the UTV vacuums fragmented silt and transports the entrained fragmented silt through a vacuum hose into a location where the silt particles are separated from the water in which they are entrained. The UTV carries a first sonar for continuously scanning the basin floor and which is utilized to guide the UTV. A second sonar is placed in the basin in a known location and continuously scans and continuously monitors the location of the UTV on the basin floor. An operator remotely guides the UTV from an onshore location.Type: ApplicationFiled: April 3, 2006Publication date: October 12, 2006Inventors: William Crawford, William Crawford

Publication number: 20050161380Abstract: An apparatus and method are provided for removing accumulated underwater debris from a reservoir for a recirculating water system, such as used for a fountain or decorative pond. An eductor is provided which is driven by a high pressure water pump. The high pressure creates a vacuum which is utilized to actuate a vacuum line. The vacuum line is moved to and fro in the reservoir to entrain the debris from the reservoir in water and to carry the entrained debris to the eductor. The entrained debris is discharged from the eductor into a separator having a permeable membrane which traps the debris and allows the water to return to the reservoir. Various separators are provided. The eductor includes an adjustably mounted nozzle to adapt to different sized debris being removed from the reservoir.Type: ApplicationFiled: March 4, 2005Publication date: July 28, 2005Inventor: William Crawford

Patent number: 6817417Abstract: An ROV, wireline or diver installed subsea xmas tree debris cap has an integral corrosion inhibitor/biocide provided in the form of a solid block which is wrapped in a water soluble membrane bag. The block is suspended inside the debris cap in a basket or perforated container. After installation of the debris cap, the membrane and solid block will dissolve and sanitize the stagnant water, thereby protecting all materials from corrosion for a number of years. The debris cap also includes an environmental seal in the form of a single O ring. Furthermore, the debris cap is simplified in that it does not include a conventional debris cap-to-xmas tree lockdown mechanism.Type: GrantFiled: March 1, 2002Date of Patent: November 16, 2004Assignee: FMC Technologies, Inc.Inventors: Richard Blair, William Crawford, Martin Forsyth, Graeme J.

Patent number: 6584633Abstract: A method and apparatus provide for an automated fragrance dispenser for the application of a fragrance to dry fabrics during an industrial laundering process. In one embodiment, the fragrance dispenser is positioned outside the dryer, and preferably on the exit side of the steam tunnel in the laundering process. The fragrance dispenser includes a sensor for determining whether the garment passing on the conveyor is the type of garment to which the fragrance is to be applied, for example, a uniform shirt versus pants. The fragrance dispenser also includes a delivery system for applying the fragrance to selected garments. The delivery system also includes a timing device for dispensing the fragrance onto the garment for a controlled amount of time. In an alternative embodiment of the present invention, automated application of the fragrance to fabrics is provided in the dryer within the laundering process.Type: GrantFiled: December 12, 2000Date of Patent: July 1, 2003Assignee: Ecolab Inc.Inventors: Brian Chute, Charles A. Hodge, Richard J. Mehus, Peter W. Rauen, Thomas L. Hennemann, William Crawford, Paul Mattia

Patent number: 5986558Abstract: Provided is a modular precharge circuit capable of rapidly recharging an equipment circuit path prior to insertion of a modular fuse or modular circuit breaker. The precharge circuit includes a switch to begin the operation of precharging, and a charge indicator to indicate appropriate charging has occurred. Charging occurs through use of a resistive network which receives an inrush current due to capacitance in the equipment circuit path. Once an equipment circuit path has been precharged to a desired level, a charge indicator signifies such charging is complete and the precharged unit is removed whereafter an appropriate fuse module and/or circuit breaker module is inserted. The precharge circuit further includes a fusing element and an alarm indicator wherein when the circuit enters a fault state such that the fuse is open, the alarm indicator signifies such a situation.Type: GrantFiled: May 29, 1998Date of Patent: November 16, 1999Assignee: Marconi Communications, Inc.Inventors: William A.

Patent number: 5982610Abstract: In a multisided access communication distribution cabinet, an adjustable tie rod is configured as part of mounting units. The adjustable tie rod is located between grooming bars of the mounting unit, fitted within slots allowing for the adjustable tie rod to move within an area defined by the slots. Wires/cables are passed through an opening defined by the adjustable tie rod and one of the grooming bars. Once the wires have been located in a desired location, the adjustable tie rod is moved into close association with the grooming bar such that the wires are held in a fixed position. Thereafter the adjustable tie rod is placed in a fixed position thereby holding the wires/cables in a secure manner.Type: GrantFiled: May 27, 1998Date of Patent: November 9, 1999Assignee: RELTEC CorporationInventors: William A.
