Abstract:

A flexible hose having an end connection fitting capable of withstanding high pressures and high end loads comprises a nipple having a stop ring on its outer periphery and a plurality of protruberances between the stop ring and the rear end of the nipple. A substantially tubular inner hose portion overlies the nipple, abuts the stop ring and extends away from the rear end of the nipple. A plurality of lays of spirally wound reinforcing wires overlie the inner portion of rubber and abut the stop ring. A sleeve overlies the nipple and is spaced therefrom. The inner periphery of the nipple has a roughened surface. A substantially tubular outer portion of an elastomer abuts the rear of the sleeve and overlies the reinforcing wires outside of the sleeve. A synthetic resin permeates the space between the wires and fills the space between the inner periphery of the sleeve and the inner portion of elastomer.

Abstract:

An improved eraser holder on a pencil includes an eraser support band which can be removed in incremental sections to provide access to additional portions of the eraser after the original exposed portion has been worn down. Fracture lines on the band facilitate incremental removal of the sections, and the fracture lines are axially misaligned to strengthen the holder.
