Abstract: A double diaphragm pump includes multiple diaphragms that are mounted for reciprocation. The diaphragms are connected for simultaneous movement to form a diaphragm assembly. A first one of the diaphragms is clamped between a housing cover and a center section. A pumping chamber is formed between the first diaphragm and the cover. Pressure in the first pumping chamber is decreased to draw the diaphragm assembly towards the first fluid cover, thereby drawing the second diaphragm into a mounting position relative to the center section. A second cover is then mounted to the center section to clamp the second diaphragm between the second cover and the center section.

Abstract: An optimized thread profile (140) for joining composite materials is presented. This thread profile (140) maintains a certain material strength when used as part of a composite threaded joint (101). The thread profile (140) comprises a repeating pattern of four components: a crest region (150), a first flank (162), a root region (170) and a second flank (164). The thread profile (140) is symmetrical, that is, the dimensions of the four components do not change throughout the length of the thread profile. The crest (152) has a flat profile and the root (172) has a rounded profile. When a shaft (120) is affixed to a joining shaft (110) using this optimized thread profile (140), the flat profiles of the crest (152) of the shaft (120) and corresponding rounded profiles of the root (172) of the joining shaft (110) create a gap to accommodate a substance such as an adhesive or a lubricant.
