An end turn support structure is disclosed which permits it to be constructed with varying, preselected coefficients of expansion along its length. This characteristic allows it to expand in a similar manner to the end turns which it supports. This structure also comprises conformable members and external support apparatus that provide a means for firmly attaching the end turns to the support structure and the support structure to the stator frame.

An iron engaging slot wedge, for use in coil slots of dynamoelectric machines is made of a glass fiber core impregnated with a cured thermoset resin, and covered on at least two sides with a facing layer of a porous aromatic polyamide mat, impregnated with a cured thermoset resin.

The terminal portion of a winding end turn conductor which projects from the core member of a dynamoelectric machine is encapsulated in an epoxy potting compound by means of a casting assembly which comprises a detachable conformable pad, a plastic sleeve mold, and a portable vise. The conformable pad is fitted about the terminal portion of the conductor to provide a temporary barrier to axial flow of the epoxy compound during casting. The plastic sleeve is disposed around the terminal portion in a spaced relationship therewith and in an abutting relation with the pad to provide a barrier to the radial flow of the epoxy compound during casting. Clamping means such as a portable vise is fitted about the conformable pad and is tightened to establish a compressive union at the interface of the conformable pad and the terminal portion of the conductor to prevent leakage. A pair of spring members hold the sleeve in abutting engagement with the surface of the conformable pad during the casting process. In a preferred embodiment, a sealing compound is applied to the interface of the pad and the sleeve and also between the pad and the terminal portion of the conductor to prevent leakage. After the epoxy compound has cured, the clamping means and detachable conformable pad are removed from the assembly and can be reused to encapsulate other conductors.

A flexible substrate having a caustic resistant support and at least one membrane comprising a solid polymeric matrix containing a network of interconnected pores and interdispersed inorganic filler particles with a ratio of filler: polymer in the polymeric matrix of between about 1:1 to 5:1, is made by coating at least one side of the support with a filler:coating formulation mixture of inorganic filler particles and a caustic resistant, water insoluble polymer dissolved in an organic solvent, and removing the solvent from the mixture to provide a porous network within the polymeric matrix.
