2014/10/24 New application can be considered:
The original idea (concept) of this mechanism is to construct a new mechanical prime mover (power converter) operating under gravity force (like a water wheel, but in a different mode – reciprocating motion). However, it became clear soon that DPC is also a completely adequate mechanical model of the well-known electronic relaxation oscillator – astable multivibrator (AMV). Thus hydro analogy (as educational methodology particularly) was enriched by new additional tool which allows to visualize for students the similar processes caused by potential fields of different nature (gravitational and elelctrical accordingly). The cognitive value of DPC as the base for Educational Kit (small working model & CD) can be considered for further development.
The working model DPC in operation can be found here: https://www.youtube.com/watch?v=8W5SY651wxg&feature=youtu.be
There are many applications in which DPC can be connected directly to various useful loads of mechanical nature because both of output motions of machine (as prime mover) can be used at the same time: reciprocal in the vertical plane (by rocking beam), and the reverse rotation in the horizontal plane (by main shaft). These possibilities are illustrated on Fig. 1
We can see that loads can be specified by criterion of similarity of output motions of mechanism and motions which are required for operating of specific load accordingly. In such a way we can expect the simplest configuration for doing of specific mechanical work (on given specific mechanical load correspond) by DPC machine. We can expect also the lowest cost price in manufacturing of entire equipment and higher efficiency in operating due to minimal additional linkage (and losses accordingly) between DPC machine and load. We believe strongly that many others applications for DPC machine will be found for the specific practical loads and technological processes.
Here are presented some examples of application of DPC machine with various mechanical loads:
Example 1 Water powered piston pumps (air or water).
In this configuration DPC is combined with two piston pumps which are connected symmetrically to the rocking beam of machine. DPC uses (as prime mover) reciprocating motion of arms of the beam which is similar to the motion of pistons (as load); thus linkage is very simple, without any intermediate mechanisms (avoid extra losses). The input water flow (as working medium) can be taken from some natural sources (lake, water fall, creek, spring, and river). This application has been recommended for irrigation purposes on mountain landscapes in the rural area.
On the base of combination of DPC (as water powered mechanical driver) and water filter and desalination devices and equipment which already exist ( Katadyn, for example http://www.katadyn.com/usen/katadyn-products/products/katadynshopconnect/katadyn-desalinators/ ) the small-scale brackish water desalination system (for households and farms) can be designed and manufactured in developing countries.
