IP Buy and Sell

Sometimes we have great ideas that don’t find a home. Some are covered by patents or patent applications. We have a list below. If any sound interesting, we can provide more details and if it’s what you are looking for, make us an offer. And if you have IP for sale that you think may be relevant to us or our clients (use our Projects page as a guide) we’d love to take a look. 

 

 Patents Granted

Patent Title    Description   Status 
Control System For a Cogeneration Unit    How to interface a heat-lead microCHP system to the grid most effectively.   Granted. Sale or licensing enquiries welcome.  
Reciprocating engine and inlet system therefor   

Reciprocating Rankine cycle expander with an electronically controlled inlet valve which provides superior efficiency and maintains this efficiency at part load and varying inlet conditions, yet is simple, providing a cost effective solution.

Patent Applications 

Patent Title    Description  Status
Fluid control device and system    If you need to control water level in a tank when fed from mains supply, with convenient user adjustment of water level this is the answer. It can also automatically dump excess water from rainfall into a storm water recycling/ harvesting system, and optionally can meter both mains in and dumped water. The dump function incorporates a user override feature. We've dubbed it the Dump 'n Fill valve. 

PCT. Sale or licensing enquiries welcome.  

Prototypes available.

Hair styling device and heating system therefor      A neat invention that allows greater freedom of shape of hair curling tongs – not limited to flat plates.  Curved tongs are now in reach!  Provisional. Sale or licensing enquiries welcome. 
Temperature sensing of moving parts   A technology for cheap and convenient monitoring of temperature on rotating parts and the like.  

Provisional.  Licensing discussions for automotive applications in progress. 

Prototype available.

Fluid control and distribution device   

If you want to water the lawn using recycled water, rain water or other low pressure supply using just the sun for power look no further. 

Provisional. Sale or licensing enquiries welcome. 

Prototype available.

Heat Engine     A cost effective way to convert low grade heat to electricity. Operates on a  Rankine cycle modified to provide greater mechanical simplicity. 

PCT. Sale or licensing enquiries welcome. 

Prototype available.

Improved heat exchanger   If you need to transfer heat but cannot tolerate high pumping power requirements this heat exchanger may be the answer. Our unique construction method gives high pressure rating and low cost of manufacture. An innovative approach to heat transfer provides high heat transfer coefficients with very low fluid velocity. Suitable for both liquids and gases or any combination, as well as evaporator and condenser applications.  Perfect for clean tech applications where high energy losses cannot be tolerated – like the organic Rankine cycle heat engine this technology was developed for.  

Provisional.  Licensing enquiries welcome. 

Prototypes available.

Expander   A reciprocating expander that brings high efficiency to small (sub 10kW) machines.  Simple, cost effective, compact and perfectly balanced, it provides for expansion ratios of up to 16:1.  

Provisional.  Licensing enquiries welcome.

Door opening assistance system for motor vehicle     

Many military vehicles have a problem with large effort required by personnel to open the doors for personnel ingress and egress.  This is exacerbated by the fitment of armour which increases the weight of the door and is a particular problem when the vehicle is on an incline.  This invention is a power door actuation system that provides fast door motions but with low peak power draw on the vehicle.  It also integrates with the existing door latching systems to provide great ergonomics and intuitive operation.  Not merely an assist system for occasional use  - this is a fast power door opener for routine use and a clear step forward on existing technologies. It incorporates servo control cost effectively to enable the user to open the door as quickly or slowly as desired.

Low cost variable valve timing and lift system for IC engines   

This technology is a simple hydraulic summing technology that  provides all the combinations of lift and phase on both inlet and exhaust that engine designers want without the pumping loss and efficiency penalties.  Ideal for smaller internal combustion engines. 

Provisional. Sale or licensing enquiries welcome. 

Prototype can be demonstrated. 

System for varying torque delivery in motor vehicles   N/A Vehicles with manual transmissions or automated manual transmissions lose drive torque to the drive wheels for an extended period during gear changes. This impacts on vehicle driveability. This simple, low cost  technology provides drive torque to fill this “torque hole” using drive torque energy stored previously. It can even capture vehicle braking energy thereby improving fuel economy as well.  Provisional. Sale or licensing enquiries welcome.
