Abstract: A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.

Abstract: A corneal reshaping by means of a soft contact lens to manipulate tear pressure gradient to produce a dimensional change to the surface profile of the cornea of the wearer to provide at least a temporary change in the refractive state of the eye eliminating the need for other refractive corrections. The contact lens has mechanical properties and/or a geometric shape such that when the lens is fitted to the eye the pressure applied to the eye via the lens will vary in a radial direction between at least one zone of higher pressure and at least one zone of lower pressure so that wearing the lens will over time cause a dimensional change to the surface layer of the cornea.

Abstract: A improved display board including folding portions with multiple regions for attaching and storing stationary and other items, the folding portions being multi-sided overlapping display areas for retaining various articles.

Abstract: A universal connector assembly for mounting one or more universal connectors within a pair of facing, spaced apart connector slots of a connector outlet. The connector assembly is made up of a mounting yoke and the one or more connectors. The mounting yoke contains a pair of flanges, connected by a crossbar, configured to interfit within the connector slots of the connector outlet. In addition, the mounting yoke contains bracing members and latching elements interengageable with latching elements of the connectors for fixed positioning the connectors in relation to the mounting yoke and locking the connectors in position against the bracing members. The connectors are positioned within the mounting yoke to form the connector assembly. The connector assembly is then positioned within the connector outlet to provide a secure connection location.

Abstract: A rail gauge face lubricating apparatus (10) comprising a delivery assembly (12) for delivering lubricant to the rail head (40) and a pump (14) for producing a pressure to deliver lubricant to the deliver assembly (12), the deliver assembly (12) comprising in part an actuable flow regulator whereby the delivery of lubricant through the delivery assembly (12) is governed by the actuable flow regulator. The delivery assembly is maintained in an appropriate position in relation to the rail gauge face by a two cylinder positioner (38) irrespective of the loading of the rail carriage that carries it.
