Abstract: An invalid hoist comprises a pivoted jib (3) for carrying an under arm-sling (13), which is arranged when pivoted to lift a user from a sitting position to a standing position and vice versa. The hoist includes knee engaging means (5) and is preferably mounted on a movable chassis (1). The arrangement is such that the movement of the user's upper body from a sitting position to a standing position always involves a substantial forward component. In preferred embodiments, this is achieved by locating the pivot (15) at substantially the level of a user's waist, by having a jib (3) which is at least twice the length of the distance between the knee joint and the hip joint, and by spacing the pivot (15) backwardly from the knee engaging means (5).

Abstract: Polyurethane compositions containing milled glass fibers alone tend to have anisotropic properties. This effect is cured by adding an effective amount of mica, preferably about 22 to 25 percent for each 5 to 8 percent of milled glass fiber.
