Patent number: 10945636Abstract: An equine respiratory detection device provides an inexpensive, portable appliance for evaluating equine health. A muzzle or mouthpiece attaches to the equine mouth region for sealably engaging with the respiratory pathway. The mouthpiece attached to a tubular vessel having a volumetric sensing apparatus for measuring respiratory inflow and outflow rates. The sensing apparatus includes a hot wire anemometer and sensing circuit for sensing flow rates based on changing electrical characteristics of a sensing element resulting from a temperature and humidity of the respiratory gases. Inhaling results in inflow gases having a cooling effect on a thermistor which affects the current flow in the sensor circuit. Similarly, exhaled outflow gases have increased temperature and humidity which allow identification of bidirectional flow and computation of an overall respiration volume to the equine patient subject.Type: GrantFiled: March 9, 2018Date of Patent: March 16, 2021Assignee: Worcester Polytechnic InstituteInventors: Lucy Garvey, Lubna Hassan, Kyla Nichols, Allison Paquin, Robert J.

Patent number: 8871034Abstract: A master verification assembly includes a plurality of plunger devices. Each of the plunger devices includes a piston that is axially moveable between a raised position and a depressed position. When placed in a washing assembly, each of the plunger devices is aligned with a nozzle. The nozzles dispense a cleaning fluid under pressure. An axial force applied by the dispensed cleaning fluid depresses the pistons into the depressed position, whereupon the pistons disposed in the depressed position are axially secured in an indicator position. Upon removal of the master verification assembly from the washing assembly, depressed pistons in the indicator position indicate proper function of the nozzles, whereas pistons disposed in the raised position indicate improperly functioning nozzles.Type: GrantFiled: April 22, 2011Date of Patent: October 28, 2014Assignee: GM Global Technology Operations LLCInventor: Matthew Kenworthy

Patent number: 7475604Abstract: A method is disclosed for monitoring an oil and gas lubricating device, with which an oil film, while forming striae, can be conveyed by an airflow along a wall of a supply line to a lubrication point, in which the temporal change in the striae is detected by a striae sensor, and a striae signal that is representative of the temporal change in the striae is generated. In order to further develop known methods for monitoring an oil and gas lubricating device, thereby preventing faults during the evaluation of the striae signal, the striae signal is smoothened by calculating an average value of the striae signal over a predetermined averaging interval.Type: GrantFiled: May 19, 2004Date of Patent: January 13, 2009Assignee: Willy Vogel AGInventor: Goetz Spiess

Publication number: 20040231430Abstract: A purge type vortex flowmeter capable of accurately measuring a flow rate of fluid over a wide range by reliably detecting the number of vortexes produced. A purge type vortex flowmeter which comprises a vortex generator (2) mounted in a passage of fluid to be measured in a flow pipe (1), two conduits (4a, 4b) having pressure ports (3a, 3b) in both side surfaces of the vortex generator for communication with the outside thereof and a front conduit (4c) having a pressure port (3c) in the front surface of the vortex generator. Purge fluid from a purge supply source is fed by a purge introducing means through a tube (5), the conduits (4a, 4b) and the front conduit (4c) into a flow of fluid to be measured in the flow pipe. Purge streams alternatively fluctuating by the effect of a difference from a fluctuating vortex pressure are discharged from the conduits (4a, 4b) through their pressure ports (3a, 3b).Type: ApplicationFiled: February 26, 2004Publication date: November 25, 2004Inventors: Minoru Oomura, Jun Tanimoto

Patent number: 6817251Abstract: Method and housing (2) for reducing particulate build-up on a surface of a device (5) contained in a recess (4) defined by the housing (2) when attached to a conduit. The method includes introducing gas into the recess (4) at a high volume and low velocity so that the gas flows in a laminar manner across the surface of the device (5). The volume lies in a range from 80 to 300 liters/minute and the velocity lies in a range from 0.2 to 3.6 meters/second. The method and housing (2) are particularly useful for preventing the build up of coal dust on the face of an ultrasonic transducer (5) used to measure the mass flow rate of coal being pneumatically transferred in the conduit.Type: GrantFiled: October 9, 2002Date of Patent: November 16, 2004Assignee: Commonwealth Science and Industrial Research OrganisationInventors: Brian David Sowerby, Stephen Rainey, Michael James Millen, Philip Thomas Rafter
