In accordance with the present invention, there is provided a novel process for modifying the surface properties of a material that is suitable for contact with animal tissue so as to enhance its hemocompatibility and make it less thrombogenic when in use. This process comprises: Exposing the surface of the material to plasma treatment conditions in order to create reactive groups on said surface; activating a molecule with an activator to produce a reactive molecular species capable of forming convalent bonds with the reactive groups created on the surface of the material to form convalent bonds. The invention further encompasses the materials produced by this process as well as devices, such as vascular prosthesis, that are comprised of these process-modified materials.

Absorbent product, such as a sanitary towel, comprising a stiffening element (6) which is intended to contribute to the three-dimensional shape of the product during its use. The stiffening element (6) is in a plane state before use of the product and has a stiffness in the dry state of in the order of 1-15 N measured according to ASTM D 4032-82. The stiffening element has a width at the transition between the crotch portion (3) and the front portion (1) on the sanitary towel which is adapted to the distance between the muscle tendons of the wearer on both sides of the crotch of the wearer in the groin of the latter and which is of the order of 1-45 mm. The product has different stiffness along a center line extending in the longitudinal direction thereof, as a result of which the product is predestined to curve in predetermined places along said center line when the product is fitted on the wearer.

A support post for a guardrail which resists impact by a motor vehicle from one direction (strong direction) and yields to impact by a motor vehicle from another direction (weak direction). The support post is adapted to receive the guardrail such that the rail face of the guardrail runs generally perpendicular to the strong direction such that the support post resists an impact on the rail face of the guardrail and yields to an impact force on the end of the guardrail.

The invention relates to an accessory for a tent, in particular to a grounding nail of pull wires of a rotatable, telescoping and anchoring type tent. The accessory consists of a rotating rod, a shell nail, an anchor-piece shaft, a movable anchor piece, a drag hook, a shell handle, a rotating handle, a contracting-piece slot and an expanding-piece port, wherein, the top of the rotating rod is provided with the drag hook; the rotating rod is arranged in the shell nail, the upper part of the shell nail is a column and the bottom of which is a self-tapping screw with a cone shape. The side wall of the lower end of the rotating rod is provided with three contracting-piece slots which form an angle of 120 degrees in horizontal direction. Each contracting-piece slot is provided with an anchor piece shaft and a movable anchor piece. The grounding nail of the invention has effective anchoring effect, is able to firmly fix even on the soft ground and is very convenient and labor-saving when being mounted and pulled out of ground.

A reusable anchor bolt template facilitates positioning of anchor bolts in anchoring material such as concrete, for subsequent mounting of a vertical structure, such as a light pole or the like. The anchor bolt template comprises a template body which defines a plurality of bolt-receiving channels within which the anchor bolts are respectfully positioned. By this arrangement, the template and anchor bolt can be positioned, as an assembly or unit, on an associated cylindrical tube or like structure which contains and confines the associated anchoring material. The template can be configured to permit the introduction of the anchoring material generally to the template, with the template thereafter being removable, and reused, if desired.

An anchor device includes an expansion bolt and a fastening screw. The bolt has a tubular body. The tubular body further has a central shank and a head, which is integrally made with the central shank and has a full solid body on which a pair of longitudinal reciprocally perpendicular through slots are made which delimit four anchor segments adapted to spread outwards under the bias of the fastening screw. The central shank has a first portion arranged next to the head on which a plurality of longitudinal through slots define longitudinal anchoring tabs which expand radially outwards under the bias of the fastening screw following the spreading of the four anchor segments.

The facing element for a stabilized soil structure comprises a body of cast material inside which a path is formed for a reinforcement strip between two points of emergence situated on a rear face of the element. This path includes two rectilinear portions which are respectively adjacent to the two points of emergence and are each arranged so as to position the strip in the same plane of emergence perpendicular to the rear face, two curved portions which respectively continue the two rectilinear portions and are arranged so as to deviate the strip from the plane of emergence, and a connection portion which joins the two curved portions to one another and has at least one loop situated outside the plane of emergence.

A thread-forming screw includes a screw end, a shank, and a thread-free head, wherein the shank is provided at least partly with a thread and has a pre-forming region, an intermediate region, which is arranged to follow the pre-forming region, and an anchoring region, which is arranged so as to adjoin the intermediate region and below the head, wherein the pre-forming region is arranged so as to directly adjoin the screw end.

A support post for a guardrail has a strong axis and a weak axis which is substantially perpendicular to the strong axis. The support post is adapted to receive a guardrail such that the rail face of the guardrail runs generally perpendicular to the strong axis such that the support post resists an impact on the face of the guardrail and yields to an impact force on the end of the guardrail.

The invention provides a method for strengthening a reinforced concrete beam through distributed external prestressing cables. Loose portions of the surface are removed, a left anchoring bolt and a right anchoring bolt are respectively and correspondingly arranged on two sides of a strengthened reinforced concrete beam, the middle bottom portion of the strengthened reinforced concrete beam is high, a steering rod notch can be installed at the middle bottom portion of the strengthened reinforced concrete beam, the cables pass through the left anchoring bolt in winding mode by adopting a continuous winding method, a cementing material is coated at the anchoring position to install an anchoring plate, the cables are connected and tightened on the right anchoring bolt through a clamping buckle, a cementing material is filled at the anchoring position to install an anchoring plate, and the anchoring plate is tightened. After the cementing material is hardened, a tension device is used for performing synchronous tension, and then the steering rod with glue is installed in the notch to support the cables. After all the cables are installed, adhesion agent is painted, polymer mortar is smeared to cover the cables and the anchoring plates, and screeding maintenance is performed. The high-strength cables are arranged in distributed mode, a vertical tension method is used, tensile force is reduced greatly, and construction is convenient. The cables are arranged in distributed mode so as to enable stress of construction members to be more reasonable.

A planting assembly (10) including a flexible trough member (12) which may selectively form a plurality of members which may be then selectively interconnected in any desired manner.

A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and / or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.
