A method and apparatus is provided for regulating the flow of rates of particulate matter. The invention includes a flow gate with a generally cylindrical body having a flow path defined there through. A stator member is provided in fixed position relative to the cylindrical body. The stator member has a plurality of alternating tapered vein portions and inlet portions. A rotor member is interfaced with the stator member. The rotor member has a plurality of alternating stock portions and outlet port portions. The rotary coupling is utilized to couple the rotor member and the stator member. A position actuator is provided for receiving at least one control input and producing a corresponding displacement of the rotor member. A mechanical coupling is provided between the position actuator and the rotor member. The flow gate is utilized to obtain a particular flow rate within a range of available flow rates by determining the relative positions of the inlet ports of the stator member and the outlet ports of the rotor member.

Method and apparatus for improved regulation of flow of particulate matter

An apparatus for supporting a human or animal body, while selectively cooling weight-bearing areas of the body in order to prevent or reduce damage from ischemia includes a cooling layer that is partitioned into a plurality of zones, and a surface disposed over the cooling layer to support the body. Each zone of the cooling layer is disposed for cooling a respective portion of the surface. Means are provided to selectively operate one or more zones of the plurality of the zones to cool a portion of the surface that receives pressure from a weight-bearing surface of the body being supported.

Support apparatus with a plurality of thermal zones providing localized cooling

A weight-bearing apparatus such as a cushion, prosthetic device, or bed mattress includes a support surface having a shaped or sculpted portion that conforms to the shape of a body portion being supported. The shaped portion fits to the body portion, thereby to position the body portion so as to situate one or more weight-bearing parts of the body portion over specific zones of the support surface that are cooled below normal body temperature. The reduced temperature applied to the zones of the support surface removes heat from the weight-bearing areas, thereby reducing the risk of injury to tissue in those areas.

The reduced temperature applied to the zones of the support surface removes heat from the weight-bearing areas, thereby reducing, the risk of injury to tissue in those areas.

A focal cooling apparatus includes a cooling, or heat sinking, layer over which a layer of compressible, thermally insulating material is disposed. The layer of compressible, thermally insulating material has a surface for supporting a portion of a human (or animal) body. The layer of compressible, thermally insulating material responds to pressure exerted against the surface by exhibiting a thermal resistance between the surface and the cooling layer that varies inversely with the pressure. Means are provided for maintaining the cooling layer at a predetermined temperature below normal human temperature.

An assembly for permitting temperature measurements at a large number of locations within a vessel, which assembly has a spreader-reducer for compacting a significantly large number of thermocouple cables into a relatively small volume so as to permit passage through one or more vessel nozzles. The thermocouple cables each has a heat expansion portion as well as a seat, thereby permitting a series of horizontal arrays of thermocouple junctions positioned at different depths within the vessel.
