Abstract: A tire pressure control system (10) for wheels (28) of a vehicle. The system includes an air control circuit (40) having a positive pressure air source (42), a vacuum pressure air source (44), a central control unit (46), a vehicle speed sensor (47), and a command/display console (48). The control circuit (40) includes valves (62,64,66,68,70) and a conduit assembly (74) for controlling communication of the positive and vacuum pressure air to wheel valve assemblies (14) mounted on each wheel. A vent valve (86) provides quick venting of positive air pressure in the conduit assembly (74) for effecting rapid closing of a valve device (100) in each wheel valve (14). Each wheel valve also includes a valve device (104) providing substantially unrestricted air flow from the conduit assembly (74) to the wheels when valve device (100) is open and providing restricted air flow from the wheels to the conduit assembly (74) to ensure closing of the valve device (100 ) when the conduit is vented.

Abstract: A method for producing a photo album page composed of superposed panels of transparent polypropylene film joined together by parallel lines of adhesive to define channels, each of which is divided by a paper strip into front and rear compartments to accommodate photos. To make photo album pages of this type, two webs of polypropylene film are concurrently advanced into combining rolls. Applied to the inner surface of one of the polypropylene webs are parallel lines of hot-melt adhesive whose chemistry is such that it has an affinity for polypropylene. When the webs are adhered together in the combining rolls, the lines create a plurality of channels. Also concurrently fed into the combining rolls in the spaces between the lines are a like plurality of paper tapes, whereby emerging from the rolls is a composite web which is then slit into individual album pages.

Abstract: A method and device (1) for applying threads (9) on a support (11) in order o obtain a ply (13) while imparting a sinuous form to the threads. There is used a rotary drum (2) having rows (4A) of fixed teeth (5A) and rows (4B) with movable teeth (5B) which are displaced parallel to the axis of rotation of the drum. Plies obtained with this method or device and articles incorporating such plies, such articles being, for instance, tires.

Abstract: A profile strip has a closure element, made of a first material, which contains a base surface, and lateral webs or flanges extending from the base surface on each side of the closure element. An adhesive layer, made of a second material, different than the first material, is attached to the lateral webs, but not to the base surface, by co-extrusion of the adhesive layer with the lateral webs. The adhesive layer is subdivided into adhesive ribs, with each pair of the two adjacent ribs separated from each other by an adhesive-free area. Sub-dividing the adhesive layer into ribs separated by an adhesive-free area substantially eliminates the deformation of the lateral webs when they--and the adhesive ribs--are cooled after the coextrusion.

Abstract: The invention disclosed here is a method for forming and curing an intricate structure of criss-crossing composite stringers and frames that are bonded to a skin panel. A structure constructed in accordance with the invention would be well-suited for use as a portion of an aircraft fuselage, a boat hull, or the like. The method is preferably practiced by applying uncured composite stringers to an uncured composite sheet panel. This is followed by placing cured frames crosswise over the stringers. The frames have openings at the locations where they intersect with the stringers which enables the frames to come into direct contact with the skin along most of their length. During the forming and curing process, the stringers are covered with a plurality of cauls, and the entire assembly of skin panel, stringers, frames and cauls is subjected to a vacuum bagging and curing process. The cauls serve to maintain both part shape and to control the flow of resin within the stringers as they are cured.

Abstract: A pneumatic radial tire is disclosed, including an annular tread having a belt incorporated therein, a pair of sidewalls which extend radially inward from both ends of the annular tread and a bead portion, provided at the inner end of each sidewall, wherein the belt includes a belt ply having a plurality of belt cords in parallel arrangement, the belt cords being formed by twisting a plurality of steel filaments or two or more strands each consisting of a plurality of steel. filaments, and at least one of said steel filaments being replaced by a filament of a shape-memory alloy which, before it is twisted either as a belt cord or as a strand which forms a belt cord, has been heat set at a predetermined heat set temperature whereby the filament has a linear shape at a temperature below the heat set temperature and has a wavy shape at a temperature at or above the heat set temperature.

Abstract: The disclosure relates to a carpet, a process for manufacturing a carpet and a method for recycling a carpet. The carpet of the present disclosure includes a primary backing having tufts of synthetic carpet fibers protruding from a top surface and, optionally, a secondary backing, with an extruded sheet of an isotactic polyolefin polymer between and integrally fused to a bottom surface of the primary backing and an upper surface of the secondary backing. The process for manufacturing the recyclable carpet includes contacting the extruded sheet with the primary backing and, optionally, the secondary backing, at a temperature sufficiently high to integrally fuse the extruded sheet to the respective backing. The method for recycling synthetic carpet of the type described includes manufacturing the carpet, collecting portions of the carpet, and melting the collected portions to make a feedstock.

Abstract: A padded strap for brassieres and similar garments that includes an integral molded pad portion. The strap, including the pad, is suitable for forming the load-bearing straps of the qarment while presenting an attractive, smooth and seam-free outer appearance and also being free of seams along the wearer's skin. The padded strap of the invention also may be used as a separate pad for a conventional strap by attaching appropriate hooks or other hardware to the ends of the strap. A method for forming a strap according to the invention is also disclosed. The method includes laminating selected fabrics to a resilient core to form a laminated sandwich, molding the sandwich under pressure and temperature to compress a portion and leave an uncompressed portion to form a pad portion, cooling the molded sandwich in a curved position to induce a curved set, cutting the molded sandwich to size to form a strap, and securing the strap to a garment.
