Member's Inventions in Development.



This section describes inventions which are not yet on the market but which members wish to reveal in the public domain. They may be looking for partners to develop concepts into real designs or products, seeking to licence, manufacture or market inventions, needing specific expertise to solve particular problems, or promoting their ideas generally.


Interested parties should contact the inventor directly or via the  secretary at



Flood Bag for Vehicles and Household Items
Cyber crime


The Concept is 15+ years old and is designed to beat the Hackers & to protect against the criminals

from stealing personal identities.



Looking for partners interested in developing this idea into products for many applications.




Inventor: David Sykes



Folding Mains Plugs with Data Networking
link 1

This mains plug can fit either the standard British socket, or a smaller new format socket by folding the pins into the body of the plug. The concept is robust enough for all the normal applications and incorporates the standard sized fuse. An extra contact in the centre of the earth pin provides data networking, allowing anything plugged into the new format socket to communicate with anything else or with the internet.


Looking for partners interested in developing these ideas into products. If the new socket format is not favoured, the data networking ideas could still be incorporated into an upgraded version of the traditional design.    Inventor: John Kinghorn



Railway carriage design
Railway Carriage Design

This coach design concept is optimised for the British main line railway network, which has unusual characteristics of a restricted loading gauge and high platforms. The design has a partially articulated structure with relatively short vehicle bodies, to give a more spacious interior while preserving a ‘go-anywhere’ route availability. In addition, wheels are partially recessed and floors are lowered to give step-free access from platforms.


The concept covers a broad range of applications including long distance stopping, commuter and inter city services. A standard vehicle structure can be fitted out in many ways according to requirements; different seating densities, powered or unpowered, sleeping and restaurant cars, driving cabs or not, etc. Some options are described in the book ‘Beyond the HST’ (Melrose Books, 2011).


Looking for partners interested in developing this vehicle design or any subsystems within it. Those using novel materials or construction techniques are especially invited to consider whether this design concept might be a suitable platform to prototype their ideas. Inventor: John Kinghorn




Train Door
Train Doors

This design combines the virtues of sliding doors and plug doors in trains, without their snags. When opening, the door moves upwards and inwards slightly before sliding sideways into a pocket behind a destination display. A robust closure is achieved, flush with the body profile for low aerodynamic drag, and the mechanism is easy to maintain.


Suitable for most trains, the design is especially useful for lower floor carriages with recessed wheels as it gives additional clearance above the bogie.


Looking for partners interested in developing a full size prototype and product, perhaps experts in composite materials as the door is a complex shape. Inventor: John Kinghorn



Energy Management System for Trains
Energy Management System for Trains


Modern passenger trains use electrical power for many purposes including lighting and air conditioning, but at present there are diverse approaches for distributing this power. This limits the interoperability of rolling stock and reduces opportunities for economies of scale in the design of subsystems. Also, improvements in electronics and battery technologies will in future provide cost effective opportunities for better energy efficiency and flexibility. This invention proposes a new architectural approach for automatically rearranging the distribution of electrical power in a common format when train formations change.


For locomotive-hauled trains, the old idea of the ‘brake van’ is revived in the driving trailer, but now recovered energy from braking is stored in local batteries and then converted to the standard power format for train services. This relieves the locomotive of that power generation task for a time until the batteries run down again, improving the overall energy efficiency of the train. The system works for electric and diesel trains, regardless of whether the traction units themselves incorporate regenerative braking or not.   


Looking for partners interested in developing these concept ideas into real products. Control, battery and inverter systems with capacities up to about 0.5MW peak loads are involved.  Inventor: John Kinghorn
