Abstract: A process for converting standard musical notes to Ra format musical notes comprising inputting a signal of standard musical notes, analyzing the frequency of each note in the signal, selecting a Ra format natural harmonic resonance, converting the frequency of each note in the signal to a Ra format frequency corresponding to the selected Ra format natural harmonic resonance, and outputting a signal consisting of the converted notes. A apparatus including a processor capable of performing the inventive process on a signal of standard musical notes. The apparatus including a signal input port and a signal output port, means for converting the frequency of standard musical notes to a corresponding frequency of Ra musical notes, means for selecting a Ra format natural harmonic resonance, and a frequency analyzer.

Abstract: A fuel injection pump includes a pumping plunger which is slidably mounted within a cylinder formed in a barrel. The barrel is provided with a pair of opposed ports which are covered by the plunger during its inward movement. The aforesaid ports permit fuel to flow into the pumping chamber when the plunger moves outwardly. Cavities can form in the fuel in the aforesaid ports prior to closure of the ports by the plunger and such cavities when they collapse can cause damage to the working surfaces of the plunger and cylinder. Channel means is provided to allow fuel to flow from the pumping chamber into at least one port to displace the cavities therefrom during the pumping stroke of the plunger.
