Role of General and Gene-specific Cofactors in the Regulation of Eukaryotic Transcription

1329610 Rod couplings JOSLYN MFG & SUPPLY CO 30 Sept 1970 [31 Dec 1969] 46536/70 Heading F2G [Also in Division H2] An end fitting coupled to a rod, e.g. of glass fibre, has an outer jacket with an inner surface that surrounds a portion of the rod and contains a material filling the space between surface and rod, the shape of the surface being so calculated that when the rod is loaded axially, the volume strain is uniform along the rod axis. Formulae are given for determining the shape of the inner surface of the jacket in dependence on the compressibility of the material filling the space between the jacket and the rod. As shown, a jacket 14 and a glass fibre rod 12 have a compressible substance, e.g. a zinc alloy collet 20, between them. The inner surface 15 of the jacket 14 is parabolic, approaching the parallel to the rod axis at the unloaded end of the rod. The parabolic surface 15 may be approximated by a series of straight line segments, Fig. 3 (not shown). In another form, the material filling the space between the inner jacket and the rod is a compressible epoxy resin, Fig. 4, 5 (not shown). The inner surface (36) of the jacket is of exponential form, being nearly parallel to the rod axis at the loaded end of the rod and flaring outwardly towards the unloaded end.
