39results about How to "Sufficient dimensional stability" patented technology

Conformable adhesive wound closures

A wound closure including a wound bridging portion that has sufficient dimensional stability to hold the wound edges in proper alignment, even in the face of substantial stretching of the wound closure as a whole, is disclosed. The wound closure is dimensionally stable directly over the wound. The remainder of the wound closure is preferably substantially more extensible and elastic than the wound bridging portion to improve conformability and adhesion of the wound closure to the patient. The wound closures may include opposing end portions of unequal lengths yielding an asymmetric shape that facilitates close placement of the wound closures along a wound.

Highly oriented fluoropolymer films

The present invention provides highly oriented multilayer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a polyolefin homopolymer or copolymer and an intermediate adhesive layer of a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the polyolefin layer allows the fluoropolymer layer to be stretched up to ten times its original length. Such a high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film. Coextrusion processing can be done at higher temperatures, i.e. in the range of from at about 280° C. to about 400° C. These temperatures allow films to be produced in the absence of polymer degradation and film melt fracture.

Flexible milk hose for an automatic milking plant

An automatic milking plant is provided with a short milk hose, which, due to spaced-apart elevations in its center piece, has sufficient mechanical stability vis-a-vis pressure differences as well as a high flexibility. The use of the short milk hose according to the present invention leads to a reduction of the mechanical strain on the udder and thus also reduces irritations of the animal to be milked.

Ceramic filter element and method of manufacture

A method of manufacturing a ceramic diesel particle filter (DPF) and a DPF manufactured by the method, the DPF having a ceramic filter body (1) including gas channels (18, 18′) with planar and porous filter segments (3), which are provided for the exhaust gas stream (2) to flow through them transversely to the face of the filter segments (3). The filter body (1) is formed by sintering at least one ceramic-impregnated fiber web (4) in a firing step under heat such that fibers (5) of the fiber material are burned off and the ceramic material (6) is sintered together to form the porous filter segment (3) between its two surfaces (7, 8). At least one fiber web (4) is corrugated to form the gas channels (18, 18′) and rolled up to form the filter body (1), and the cross section of at least a portion of the gas channels (18, 18′) changes from an inlet end (33) to a discharge end (34).

Plunger piston made from plastic for an air spring

A plunger piston for an air spring. The air spring being active between a component which is to be cushioned by springs, in particular the vehicle frame, and a sprung component, in particular the axle carrier of a motor vehicle. The plunger piston is configured as a hollow piston which is connected to the sprung component at the lower plunger-piston end and to a pneumatic-spring bellows which can be loaded with compressed air at an upper plunger-piston head. The pneumatic-spring bellows is connected on the other side to the component which is cushioned by springs, and rolls on the outside of the plunger-piston skirt during suspension movements. The lower plunger-piston end has an open configuration and has a reinforcing element which encircles the edge region of the opening.

Crumple resistant lining and outerwear for use therewith

A detachable lining for outerwear comprises a bodice, which includes an inner substantially full layer composed of a relatively rough fabric, an outer substantially full layer composed of a relatively smooth fabric, and an overlay partial layer composed of a relatively smooth fabric. The partial layer is superposed on the inner layer at an upper region of the bodice. The inner layer and outer layer are quilted together for enhancing dimensional stability and preventing bunching. The overlay partial layer has a relatively low coefficient of friction for encouraging sliding and preventing catching.
