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: 10888138Abstract: An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface.

Patent number: 10859262Abstract: A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.Type: GrantFiled: November 29, 2017Date of Patent: December 8, 2020Assignee: Worcester Polytechnic InstituteInventors: Shivaprasad Arava, Kemal S.

Patent number: 10836649Abstract: A low-temperature leaching operation employs a raw, red mud slurry directly from aluminum production for an oxalic acid leaching of ferric oxalate. Residual calcium, titanium, aluminum and other rare earths are also recoverable in a secondary stream. Monitoring and control of the pH of the leach solution yields soluble ferric oxalate without high temperatures or specific radiation or light sources. Addition of iron powder results in precipitation of ferrous oxalate, isolated by magnetic separation from the iron powder which recirculates in the solution. Magnetite may then be produced by heating the ferrous oxalate in low pO2 conditions.Type: GrantFiled: December 7, 2018Date of Patent: November 17, 2020Assignee: Worcester Polytechnic InstituteInventors: Sumedh Gostu, Brajendra Mishra

Patent number: 10753878Abstract: A molten metal inclusion test apparatus includes a spectroscopic appliance for gathering data indicative of the contents of a quantity of molten metal. Laser induced emissions provide spectral data based on the elements present in the melt. Analysis of a series of samplings, or “shots” of laser induced emissions indicates a presence of elements above a background or expected level. These elements appear as spikes in a graphical rendering of the spectral data, defined by a wavelength of the detected element. Correlation of the elements detected in the same shot indicates a composition of the inclusion, typically a particle of an extraneous compound in the melt. Such spectral analysis provides immediate feedback about melt quality, allowing corrective measures to be taken prior to casting.Type: GrantFiled: September 19, 2018Date of Patent: August 25, 2020Assignee: Worcester Polytechnic InstituteInventors: Shaymus W. Hudson, Diran Apelian, Robert DeSaro, Joseph C. Craparo

Patent number: 10741890Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of valuable charge materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. However, LiFePO4 is a waste stream charge material often discarded due to infeasibility of recycling. LiFePO4 is precipitated as FePO4 and remains as a by-product, along with graphite and carbon, which are not dissolved into the solution. FePO4 can be separated from graphite and carbon, FePO4 can be used to synthesize LiFePO4 as cathode materials and graphite can be regenerated as anode materials.Type: GrantFiled: May 11, 2018Date of Patent: August 11, 2020Assignee: Worcester Polytechnic InstituteInventors: Yan Wang, Xiaotu Ma
