A thick walled Moineau-style stator and method of manufacture are disclosed. The outer profile of the stator follows the inner helical profile of the stator. The application of an elastomeric layer to the inner profile of the stator results in a constant thickness for the elastomeric layer and proximity for the walls of the stator. This improves the durability of the motor because of lower heat generation and better heat dissipation. The stator walls also support the elastomeric layer. Further, ...

A profiled sheet material is formed into side panels and floor or deck panels for use of example in the manufacture of high-sided lorries, trailers and containers. The profiled sheet material (10) has a plurality of parallel deformations (11) which in cross section are substantially triangular with the base (12) of each deformation spaced from the body of the sheet. The apex of each deformation is formed by closely abutting curved faces of the sheet material (1) where the body of the sheet mater...

A composite profile member includes two metal profile bars and at least one thermally insulating, one-piece insulating bar which engages into a clamping groove of the metal profile bars. The insulating bar is fixed in the respective clamping groove by its hook-shaped groove webs which are pressed against the insulating bar, with corresponding centering means being provided at the insulating bar and in the respective clamping groove to assure dimensional accuracy when the groove webs are pressed ...

A sealing profiled strand of elastomeric materials provided with sealing lips along portions of the strand. The strands emerge from the nozzle or orifice of the extruder, at which point they still have a complete cross section. While still in the plastic state, the strands are cut by a transversely movable cutting knife which is curved in conformity to the outer contour of the strand. The strand is cut pursuant to a prescribed pattern in such a way as to remove portions of the sealing lip.

An apparatus for producing a profiled template, comprising a grinding support provided with a holder for the template, a tracing support that is fixedly connected to the grinding support, a projector having a projection screen that is provided with a marking, and a template pattern having a profile contour that is adapted to be projected onto the projection screen for moving along the marking thereof.

This invention relates to a profiled strip adapted to be used for making the join between two surface coverings making therebetween a determined re-entrant angle, wherein this profiled strip comprises: two bearing sole plates which are made of a hard, semi-rigid material, which are each adapted to be placed below one of the surface coverings and which each present an extension extending in a direction offset angularly by substantially 90.degree.; and a connecting bridge which connects the extens...

A connector which can separably couple a hollow first profiled member with a channeled second profiled member has an open-ended housing for a reciprocable clawed coupling member and an eccentric which is rotatable to move the coupling member between extended and retracted positions. The coupling member has a front projection which can be pushed by a disc of the eccentric to move the coupling member to extended position in which the claw or claws of the coupling member can enter a channel of the ...

Transverse elements (9) for a driving belt (7) abut with their principal sides (21, 22) against one another. At least one side has a profiling being convex to allow a misalignment between discs (1, 2) and (4, 5) where between the belt (7) is running to be absorbed by effecting a tilting of neighboring elements.

A tube made of profiled strip has an inner edge and an outer edge parallel to the inner edge and projecting away from the inner edge. A double-thickness rib extends between the edges projects transversely in a direction from the strip. A channel extending between the rib and the outer edge opens transversely of the strip opposite to the direction in which the strip projects from the strip. The strip is formed into turns centered on an axis with the rib projecting radially outward. The channel op...

A static mixer includes profiled layers which are arranged in a ring space and which contain mutually crossing flow channels which are inclined relative to a central axis. A fluid mixture is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis. Each layer comprises equivalent channels which extend on an inner or outer side of the layer over at least approximately equa...
