    • Embodiments of the present invention are directed to pulsed polarimeters for conducting remote, non-perturbative diagnostic measurements of inducing fields of a medium demonstrating induced optical activity. In one aspect, a pulse polarimeter includes a light source emitting a polarized light pulse having sufficiently narrow spatial extent at a prescribed wavelength and a light gathering optical system including a light gathering optic having an optic axis directed toward the medium and positioned to collect and collimate a predetermined solid angle of an emission from the medium into a collimated emission beam, while preserving the polarization state of the emission. The pulse polarimeter includes a directional coupler that makes coincident the propagation direction of the polarized light pulse with the optic axis and a polarization detection system for measuring the intensity and determining the polarization state of the collimated emission beam continuously in time as the polarized light pulse transits the medium.

    • Width enlargement means is described, which is adapted to be attached to a joist end to adapt the latter for use with a joist hanger having a joist receiving socket with diverging side cheeks therein. When attached, the cross section shape of the end of the joist becomes trapezoidal so as to form a wedge. The inclined faces engage the diverging side cheeks of the socket thereby to provide lateral support for the joist end when fitted in the joist receiving socket. One form of enlargement means for a conventional rectangular cross section joist comprises triangular cross section fillets, which are adapted to be fitted to the opposite faces of the end of a the joist. Alternatively it may comprise a wedge shaped member having a central slot into which the end of the joist is fitted. Where the joist has an I-beam cross section, fillets are secured to opposite faces of the central web of the I-beam, or the end of the latter is fitted into a slot in a slotted wedge. Alternatively at least one metal structure is adapted to be fitted to one end of the joist, and the outer faces of the metal structure or structures are spaced by a greater distance in the region of the upper edge of the I-beam section than they are in the region of the lower edge thereof. Where the joist has an I-beam cross section the metal structure(s) may be attached to the web or the upper or lower rails, or all three. However formed the included angle between the inclined faces of the enlargement means whether formed by fillets or a wedge shaped member, or one or more metal structures, is substantially the same as, but not greater, than that between the diverging cheeks of the joist hanger socket in which the joist is to be received in use.
