Abstract: A device is disclosed featuring a buckle removably attached to a size adjustment end portion of a strap having a series of size adjustment holes in the strap. A strap receiving retainer and a hook-like tongue are integrally formed in fixed relation to opposite sides of a frame of the buckle with the tongue extending through a selected hole in the underlying size adjustment strap end portion and through an aperture in a plate attached to an opposite end portion of the strap.

Abstract: A method and a device are disclosed for reducing ultraviolet and infrared degradation of a polymer core of large core polymer fiber. The method comprises coupling a large core polymer fiber with a glass rod resulting in the placement of the glass piece in the path of the ultraviolet and infrared radiation, thus intercepting the same and keeping the polymer core from being degraded due to long term exposure to low densities of ultraviolet or infrared radiation or from being destroyed in applications involving high density exposure to such radiation. The device comprises a large core polymer fiber having a glass rod incorporated therein to prevent exposure of the core of the fiber to ultraviolet and infrared radiation.

Abstract: A method of making a recess in a drive socket and the like includes forming a groove to extend along a face of an elongated drive opening in a metal workpiece from one end of its drive opening, moving material from the surface of the groove to increase its depth from its outer end along only a portion of its length and gathering the material so moved from the groove surface to form a ledge between ends of the groove, whereby a recess is defined by the groove extending beyond the ledge. In addition, a female drive device for socket wrenches and the like is disclosed having an elongated drive opening, a groove longitudinally extending from one end of the drive opening along a face of the drive opening, and a ledge between ends of the groove. The ledge protrudes radially inwardly such that a recess is defined by the groove extending beyond the ledge for retaining a male drive member.

Abstract: A quick change system and method of interchanging molds on plastic extrusion blow molding machines is disclosed wherein a universal standard subplate is provided for use with different blow molding machines on which a variety of different mold units are removably mounted on the standard subplate with the subplate establishing a preselected precisely aligned relation automatically between the mold unit and a machine platen. A quick release locking device is provided between each mold unit and a unitary standard water manifold and detabber assembly. The unitary standard assembly is provided as a one-piece component with fluid connections communicating respectively with water and air supply sources of the water manifold and detabber and which are conveniently maintained attached without being disconnected during detachment of the unitary standard assembly from the mold unit during a mold change.

Abstract: A finished flooring underlayment is disclosed including a flexible membrane which is resistant to water, mold and deterioration under wet or dry conditions, and which has intertwined filaments bonded to the membrane surface that act as mortar reinforcement and as gauges to provide a uniform thickness of application for cementicious mortar. The mortar is provided separately and is mixed to a suitable consistency with either water or latex additive, then poured or placed on the mat, utilizing the gauges provided by the filaments to effect a uniform thickness of application. This mortar hardens to a strong, load bearing surface or slab suitable for application of finished flooring.
