Abstract: A heat exchanger includes an inlet for receiving bulk solids, a plurality of heat transfer plate assemblies, a plurality of spacers disposed between adjacent heat transfer plate assemblies, and supports for supporting the heat transfer plate assemblies. The heat transfer plate assemblies include a first plate having a first pair of holes extending therethrough, the first plate having channels extending along a surface thereof, for the flow of fluid through the channels, and a second plate bonded to the first plate to enclose the channels, the second plate including a second pair of holes generally aligned with the first pair of holes to form through holes to facilitate flow of the fluid through the through holes and the channels.

Abstract: Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

Abstract: Systems and methods for providing tuition enrollment insurance for institutions of higher education (IHEs). The tuition enrollment insurance can be based upon parametric analytic triggers. The systems and methods can provide a tuition enrollment insurance data input interface, statistical modeling, visual analytics, a user selection interface, and a monitoring interface for tracking compliance and results.

Abstract: An overload relay is disclosed in which a single operator coil is controlled for both tripping and resetting. A permanent magnet and a spring make the device bi-stable, so the coil may be unpowered when in the trip and reset states. Energization of the coil overcomes the magnet to allow tripping, while energization in an opposite direction adds to the magnet force to reset the device. An electromagnetic activation path overrides a mechanical activation path for electromagnetic tripping despite attempted manual resetting. The device may be pulse width modulated to reduce power consumption.

Abstract: A fertilizer application system for a liquid fertilizer concentrate includes a container containing a first fluid. A siphon is disposed on the container and includes two inlets and an outlet. A flow control valve is configured to selectively control an amount of first fluid flowing through the siphon based on ambient temperature of an environment outside the container. A siphon tube includes a siphon tube first portion in fluid communication with the first fluid, and a siphon tube second portion fluidly coupled to an inlet of the siphon. The first fluid includes a liquid fertilizer concentrate comprising a nitrogen containing source, a phosphorous containing source, a sulfur containing source, a potassium containing source, an iron containing source, and water.

Abstract: A vaporizer cartridge system includes a vaporizer assembly containing a heating element, a mouthpiece that is selectively attachable with the vaporizer assembly, a battery assembly that is selectively attachable with the vaporizer assembly, and a cartridge configured to store liquid in a reservoir, the cartridge being selectively attachable with the vaporizer assembly such that liquid stored within the reservoir is in fluid communication with the vaporizer assembly. The vaporizer cartridge system is configured such that when the cartridge and the mouthpiece are attached to the vaporizer assembly, the cartridge fits within the mouthpiece.

Abstract: An overload relay is disclosed in which a single operator coil is controlled for both tripping and resetting. A permanent magnet and a spring make the device bi-stable, so the coil may be unpowered when in the trip and reset states. Energization of the coil overcomes the magnet to allow tripping, while energization in an opposite direction adds to the magnet force to reset the device. An electromagnetic activation path overrides a mechanical activation path for electromagnetic tripping despite attempted manual resetting.

Abstract: The invention provides a high-frequency acoustic waveguide for use in coaxial loudspeaker systems. The waveguide is made up of a plurality of walls that define a conduit with an input end and an output end. Each of the walls includes a mask layer and a perforation layer. The mask layer has a plurality of holes sized and shaped to make the mask layer acoustically transparent to sound waves below a crossover frequency. The perforation layer has a plurality of micro-perforations sized and shaped to make the perforation layer acoustically opaque to sound waves above the crossover frequency. The waveguide directs sound waves above the crossover frequency, and is acoustically transparent to sound waves below the crossover frequency.
