Title: Ladder attachment platform

Abstract

A ladder attachment platform is provided that includes a base for attachment to a ladder that has first and second side rails and a plurality of rungs that extend between in a lateral direction. Also included is a user platform for having a user stand thereon that is carried by the base. The user platform may be positioned with respect to the ladder so that it is not located between a first plane that extends through the first side rail and is perpendicular to the lateral direction and a second plane that extends through the second side rail and is perpendicular to the lateral direction.

Turbine blade and non-integral platform with pin attachment

Patent Campbell, Christian Xavier; Eng, Darryl; Marra, John J.

Platforms (36, 38) span between turbine blades (23, 24, 25) on a disk (32). Each platform may be individually mounted to the disk by a pin attachment (42). Each platform (36) may have a rotationally rearward edge portion (50) that underlies a forward portion (45) of the adjacent platform (38). This limits centrifugal bending of the rearward portion of the platform, and provides coolant sealing. The rotationally forward edge (44A, 44B) of the platform overlies a seal element (51) on the pressure side (28) of the forwardly adjacent blade, and does not underlie a shelf on that blade.

Piezoelectric biosensor with a ladder polymer substrate coating

Patent Renschler, Clifford L [Tijeras, NM]; White, Christine A [Albuquerque, NM]; Carter, Robert M [New Orleans, LA]

A piezoelectric biosensor substrate useful for immobilizing biomolecules in an oriented manner on the surface of a piezoelectric sensor has a ladder polymer of polyacrylonitrile. To make the substrate, a solution of an organic polymer, preferably polyacrylonitrile, is applied to the surface of a piezoelectric sensor. The organic polymer is modifying by heating the polymer in a controlled fashion in air such that a ladder polymer is produced which, in turn, forms the attachment point for the biomolecules comprising the piezoelectric biosensor.

Fluorescent conjugated polymers containing semi-ladder units for light-emitting field-effect transistors

Patent Yu, Luping; Awais, Mohammad A.; Sharapov, Valerii; ...

Materials are provided for use as active emissive layers in organic electronic devices such as light-emitting filed effect transistors. Light-emitting transistors (LET) are an alternative to light-emitting diodes and have several important benefits, however, materials developed specifically for LET are quite scarce. Herein a new family of materials is disclosed that has been developed specifically for LET.
