A diaphragm pump for gas-containing fluids, in which the chamber for the fluid to be pumped is of frusto-conical shape corresponding to the elastic diaphragm, the minor-diameter edge of which is connected to a rigid central disc provided at its periphery with a frusto-conical support surface for the underlying diaphragm. A protection system is provided for the elastic diaphragm.

Polyphase fluid diaphragm pump

An operating system for the flexible gripper tapes in shuttleless looms in which the backing plate that limits upward motion of the tape is located in the region where the unwound tape is not engaged by the drive wheel, and which plate is provided with suitably disposed holes fed with compress air. The compressed air guides the tape and helps prevent undesirable buckling.
