  • Patent number: 9441575
    Abstract: A thermal energy recovery system. The system includes a Stirling engine having a burner thermal energy output. Also, a superheater mechanism for heating the thermal energy output and an expansion engine coupled to a generator. The expansion engine converts the thermal energy output from the burner to mechanical energy output. The generator converts mechanical energy output from the expansion engine to electrical energy output. The expansion engine may also includes vapor output. Some embodiments of the system further include a condenser for condensing the vapor output, a pump for pumping the vapor output and a boiler in fluid communication with the pump. The pump pumps the vapor output to the boiler.

  • Patent number: 9308467
    Abstract: A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid. The fluid vapor distillation apparatus also includes a control system.

  • Publication number: 20160097382
    Abstract: A peristaltic pump, and related system method are provided. The peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, and a spring-biased plunger. The first and second pinch-valve cams are coupled to the cam shaft. The first and second pinch-valve cam followers each engage the first and second pinch-valve cams, respectively. The plunger cam is coupled to the cam shaft. The plunger-cam follower engages the plunger cam. The tube receiver is configured to receive a tube. The spring-biased plunger is coupled to the plunger-cam follower such that the expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam follower towards the plunger and thereby disengages the spring-biased plunger from the tube. A spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube.

  • Patent number: 9151646
    Abstract: An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a curved, elongated support member elastically deformable and having first and second ends. The apparatus also include an opposing support member configured to position a tube against the curved, elongated support member between the first and second ends. Deformation of the curved, elongated support member by movement of the first and second ends toward each other reduces an internal volume of the tube.
