Publication number: 20220072253Abstract: A tubular applicator is releasably connected at a first end to the collar of an adhesive peristomal baseplate to assist the user in positioning the baseplate around a tracheostoma on the user's neck, where the applicator defines an internal flowpath which is placed in fluid communication with the tracheostoma via the collar of the baseplate, and the flowpath opens outwardly via at least one outer aperture in the applicator, and where the at least one outer aperture has a total section area greater than a first section area of the flowpath at the first end of the applicator.Type: ApplicationFiled: June 1, 2021Publication date: March 10, 2022Inventors: Ian David WORTHINGTON, Alexander James BRIERLEY

Publication number: 20220054782Abstract: A shower shield for use with a tracheostoma, having a chamber with a port for connection to a speaking valve or tracheostomy base plate, and a downwardly-facing aperture, and further provided with a resiliently-deformable wall region so that a user's finger pressure on the wall region said region can actuate the speaking valve or occlude a tracheostoma.Type: ApplicationFiled: February 14, 2020Publication date: February 24, 2022Inventors: Ian David WORTHINGTON, Alexander James BRIERLEY

Publication number: 20220054781Abstract: A speaking valve for use with a tracheostomy and voice prosthesis having a valve element movable by finger pressure between a first position in which the valve allows air to pass through it and a second position in which the passage of air is substantially resisted or prevented. A biasing element such as foam or a spring is provided to bias the valve element towards the first position when no finger pressure is applied. The valve element is arranged such that expiration through the valve at a rate in excess of predetermined rate causes it to move into a third position in which air resistance through the valve is less than when the valve element is in its first position. This allows for air release if e.g. a user should cough.Type: ApplicationFiled: January 14, 2020Publication date: February 24, 2022Inventors: Ian David WORTHINGTON, Alexander James BRIERLEY

Publication number: 20220016373Abstract: A speaking valve for use with a tracheostomy and voice prosthesis, that, in a first configuration, allows inspiration and expiration through the valve; and in a second configuration resists expiration. Increasing the pressure difference across the valve by increasing the rate of expiration to a predetermined threshold causes the valve to transition into the second configuration; and the second configuration the valve continues to resist expiration until a predetermined negative pressure difference across the valve causes it to transition back into the first configuration.Type: ApplicationFiled: November 22, 2019Publication date: January 20, 2022Inventors: Ian David WORTHINGTON, Alexander James BRIERLEY

Patent number: 9789889Abstract: A slack adjuster for narrow gauge rail cars including a housing having a body with a first clevis joint, a coupling secured to the body, and a guide tube secured to the body coupling. A lever is pivotally coupled to the housing for moving an actuator coupled to a clutch. The clutch is engaged with the external threads of a rod and moveable between a first captured position, a second position where the clutch is free to rotate, and a second captured position to selectively control movement of the rod. Movement of the lever withdraws the actuator so that the clutch releases and can spin, allowing the threaded rod to translate from the retracted to extended positions. Opposing forces applied to a ram causes the clutch to move to the second captured position, thereby preventing rotation of the clutch and preventing the threaded rod from retracting further into the housing.Type: GrantFiled: October 24, 2014Date of Patent: October 17, 2017Assignee: New York Air Brake, LLCInventors: Brian Graves, Jeffrey Sauter, Derick Call, James Brierley

Processing of acid-consuming mineral materials involving treatment with acidic biooxidation effluent
Patent number: 7514050Abstract: In one aspect the present invention provides a method of recovering gold from each of at least two different refractory gold-bearing sulfidic mineral materials. A first mineral material is subjected to biooxidation pretreatment to release gold locked within sulfide minerals. The biooxidation produces an acidic biooxidation liquor effluent that contains significant dissolved iron in the ferric form. All or a portion of the biooxidation liquor effluent is used as an acidic treatment liquid to treat the second mineral material, which contains acid-consuming minerals. During the treatment, acid-consuming minerals react with the acidic solution, raising solution pH and resulting in reduced solubility and precipitation of dissolved iron and other metals. Also during the treating, sulfides in the second mineral material or oxidized, thereby releasing gold for subsequent recovery.Type: GrantFiled: June 6, 2005Date of Patent: April 7, 2009Assignee: Newmont USA LimitedInventors: James A. Brierley, Fritz-Peter Sawyer -

Patent number: 5127942Abstract: A method is provided for the recovery of precious metals, such as gold and silver, from refractory carbonaceous sulfidic material. The carbonaceous sulfidic material is ground and placed in heaps or piles or pulped or slurried and bioleached to oxidize the sulfide minerals using bacteria at temperatures from about 15.degree. C. and up to about 40.degree. C. The biooxidized residue is then treated using a specific microbial consortium, or a product of the microbial consortium, at temperature from about 5.degree. C. to 40.degree. C. to deactivate the carbonaceous component of the material to prevent binding of the precious metal to the carbonaceous component. The precious metal liberated in the residue remaining from the biological oxidation of sulfide and deactivation of carbon are recovered by dissolution.Type: GrantFiled: August 20, 1991Date of Patent: July 7, 1992Assignee: Newmont Mining CorporationInventors: James A.
