Title: Liquid fuel injection pumping apparatus
IPC: F02M59/30
Filed: 1979-10-25
Abstract: A rotary distributor fuel injection pumping apparatus has a rotary distributor member rotatable within a sleeve forming part of the body of the pumping apparatus.

Title: Broad-band pulsation attenuator
IPC: D21F1/06
Filed: 1980-03-08
Abstract: An insert type attenuator arranged to function as a broad-band frequency rejection filter for pulsations in a liquid in a conduit, such as a liquid stock suspension being fed via a pipe line to a paper making headbox, which includes a housing, a conduit positioned within the housing, and a flexible diaphragm having a pair of substantially horizontal spaced runs positioned in the conduit, with means for flowing the stock suspension through the conduit, and means for introducing pressurized gas into and bleeding gas from the housing and the space between the diaphragm runs. Valve means operate intermittently in response to gross outward deflection of one or both of the runs, caused by long-term liquid pressure decreases and/or gradual increases of gas pressure build-up, to vent gas from between the runs and from the housing, and thus to maintain adequate matching of the pressures of the gas cushion and of the liquid. This maintaining of the diaphragm in a neutral, sensitively responsive condition permits it to deflect instantaneously, in both directions, as required, to reflect pulsations in the liquid.
