摘要： A fluid flow control valve which is mechanically programmable to enable the control of flow rate and/or timing of the supply of fluid therethrough. The valve comprises a housing having an inlet and outlet portion. An axially extending passageway within the housing is in fluid communication with the inlet portion. A fluid flow control and timing mechanism is disposed within the axially extending passageway and configured to travel a defined path(s) along the axis thereof when pressurized fluid is supplied to the passageway. The fluid flow control and timing mechanism is configured to cooperate with the outlet portion to control the timing and flow rate of fluid therethrough. To enable the flow control mechanism to traverse the defined path(s) of travel, a biasing mechanism is associated with the fluid flow control and timing mechanism to respond to the application of pressurized fluid into the axially extending passageway. The invention provides a mechanically programmable valve which is particularly useful for controlling the flow of fluids without the need for electrically actuated control systems.

摘要： A device and a process for measuring fuel quality and/or economy is provided by this invention. The specific gravity of fuel is measured by any suitable means such as a hydrometer; the temperature of fuel is measured by another means, such as, a thermometer. Third means responsive to the measurements obtained by first two means converts the specific density of the fuel to specific density at a predetermined temperature and from that to fuel quality. The fuel quality can then be converted to fuel economy when the price of fuel is known. Alternatively, specific density of fuel corrected to the specific density at a predetermined temperature can be converted directly to fuel economy if the price of the fuel is known. For conversions described above suitable nomographs can be used.
