Abstract: This invention relates to a tree climbing device including a number of frame sections and a pair of platform sections pivotally and slidably secured to the frame sections. The frame sections can be secured to a tree or other vertical structure and the platform sections can be sequentially vertically slid along the frame sections and engaged with the frame sections to enable an individual to climb the tree along the frame sections while being supported by the platform sections.

Abstract: An overflow protection system for an oil tank trailer which automatically monitors and controls the level of oil within said trailer. The system comprises a float sensor, a cable assembly, a shutoff valve, a temperature sensor, and a control box. The float sensor comprises an inductive float sensor which monitors the level on the tank gauge of an existing trailer body, which provides electrical signals via the cable assembly. The cable assembly provides electronic connection between the float sensor, valve, temperature sensor, and control box. The shutoff valve is closed when the float sensor is triggered, preventing flow into and out of the tank in order to eliminate overflow spillage. The control box includes a plurality of manual user controls for operating the system as well as information displays including interior temperature and the like.

Abstract: A drive assembly (2) for a pen-type injector, comprising: a guiding means (40) having a first (42) and a second end (41), a drive means (20), an elongate member (30) coupled to the guiding means (40) and adapted to be driven by the drive means (20) for displacing the guiding means (40) with respect to the drive means (20), a piston member (60) displaceably disposed at the first end (42) of the guiding means (40) and an adjusting member (62) displaceably disposed at the second end (41) of the guiding means (40), wherein the drive means (20) is fixedly located with respect to the adjusting member (62), and wherein the piston member (60) and the adjusting member (62) are coupled such that the sum of the distance between the piston member (60) and the guiding means (40) and the distance between the adjusting means (62) and the guiding means (40) remains constant, and a pen-type injector with such a drive assembly.

Abstract: Disclosed herein are hard surface cleaners which provide improved fragrance retention properties to the treated hard surface, and methods for using them. The cleaners include a fragrance, a carrier, and a surfactant selected from ethylene oxide/propylene oxide block copolymers, polyglycosides, ethoxylated alkyl alcohols, and ethylene oxide/propylene oxide copolymers functionalized with a fatty alcohol moiety. The cleaner may also contain water and a base.
