Abstract: Disclosed is a shaped article comprising a continuous oriented thermoplastic polymer matrix having dispersed therein microbeads of a polymer which are at least partially bordered by void space, the microbeads being present in an amount of about 5-50% weight based on the weight of said oriented thermoplastic, said void space occupying about 2-60% by volume of said shaped article. Preferably, the microbeads are cross-linked to an extent they will be resilient and elastic at the orientation temperature, and are coated with a slip agent. The shaped article is preferably in the form of a sheet, fibers, or other molded article, and preferably has a relatively low specific gravity and whiteness.

Abstract: The present invention relates to a method of forming shaped articles having a continuous phase of an oriented thermoplastic polymer containing cross-linked polymer microbeads at least partially bordered by void space. The thermoplastic polymer in molten form is mixed with a plurality of the crosslinked polymer microbeads, and the mixture is then formed into a shaped article. The article is stretched in at least one direction to orient it. The orienting conditions and the character and quantity of crosslinked polymer microbeads is effective to form voids in the article at least bordering the microbeads on sides thereof in the direction(s) of orientation.

Abstract: An apparatus and method for transporting a load upon a vehicle is provided. The apparatus of the invention is a carrier assembly for attachment to a receiver mounted on the rear of a vehicle. The carrier assembly comprises a basket, a hitch for attaching the carrier assembly to the receiver, a riser extending upwardly and outwardly from the hitch, an extension projecting rearwardly from the riser and supporting the basket, and a pivotal connection whereby the basket may be maintained in an upright position or pivoted down and away from the vehicle. The method is carried out using the apparatus to transport loads and by pivoting the basket rearwardly and downwardly from an upright transport position to facilitate access to the rear of the vehicle.

Abstract: A wood joint connector plate is formed of a thin, rigid metal sheet having numerous narrow, elongated, struck-out openings. The struck-out sheet material is bent perpendicularly at each end of each opening to form a pair of opposing reverse-oriented mirror-image teeth. Each tooth is bent about a lengthwise bend line that is offset relative to the central longitudinal axis of its opening to divide the tooth into a narrow portion and a wide portion along its length. The free end of each tooth is formed as an asymmetrical V-shaped tip, whose apex coincides with the bend line, to provide a short leg terminating the tooth narrow portion and a long leg terminating the tooth wide portion. Each tooth is twisted around its bend line so that its tip short leg extends approximately parallel to the axis of the opening and towards its opposing tooth. The tip long leg extends away from its opposing tooth and its opening at an acute angle relative to the longitudinal axis of the opening.

Abstract: A truss plate for connecting together wood members forming trusses, joists, beams and the like construction parts, formed of stiff sheet metal having struck-out teeth extending perpendicularly to the body of the plate. The teeth are struck-out in pairs, leaving an elongated slot between each pair of teeth. The slots, and their teeth, are aligned in numerous longitudinal rows. The rows form groups whose slots are also transversely aligned, but with the slots of one group being longitudinally offset relative to the slots of its adjacent group. The teeth are V-shaped in cross-section and are axially twisted. Their free ends form asymmetrical V-shaped tips. A pair of such plates are arranged in face-to-face contact with the teeth of the uppermost plate extending through the slots in the lowermost plate for closely positioning together adjacent teeth to form a double thickness plate with pairs of double teeth.

Abstract: This disclosure improves data processing system integrity by assigning content types to virtual pages and using the assigned content types to enforce special access rules. The page content types are: (a) any changeable data and/or any executable instructions (current S/370); (b) SCP executable instructions and/or unchangeable data (SENC); (c) SCP restrictively changeable data only (system DO); and optionally (d) application data only (user DO). Page content type designation is done by providing in each PTE two integrity control flag bits called herein SENC and DO. In the first embodiment, the SENC and DO bits are separately coded to respectively control access to SENC and system DO page types. In a second embodiment the SENC and DO bits are combinatorially encoded to obtain four types. A new system integrity state, the SCP state, is provided to protect SENC and system DO page usage. The SCP state is initiated by a hardware interrupt, i.e.
