摘要:
A vehicle step assembly uses hinged pedestals and attitude links to position step stringers and an attached step beam in a generally horizontal and elevated deployed position, while permitting a space-saving tucked-in stowed position.

An assembly for use in fixing a first component of a joint prosthesis, having a bone facing surface and an exposed surface which faces towards a second component of the joint prosthesis when implanted on a patient's bone. The assembly includes a skirt which can be temporarily fixed to the edge of the first component extending along the edge thereof from a remote portion of the edge to an accessible portion of the edge. The skirt provides at least one opening through which cement located between the bone facing surface of the component and the surface of the bone can be displaced. The opening is located so that cement is prevented from being displaced at the remote portion of the edge and is instead displaced at the accessible portion of the edge.

This invention relates to new polypeptide compound represented by the general formula (I) wherein R1, R2, R3, R4, R5 and R6 are as defined in the description or a salt thereof which has antimicrobial activities (especially, antifungal activities), inhibitory activity on β-1,3-glucan synthase, to process for preparation thereof, to a pharmaceutical composition comprising the same, and to a method for prophylactic and/or therapeutic treatment of infectious diseases including Pneumocystic carinii infection (e.g. Pneumocystis carinii pneumonia) in a human being or an animal.
摘要:
A prosthetic joint for replacing a natural joint in a body includes a first prosthetic component of the prosthetic joint which, when implanted into a first resected bone of the natural joint has a junction between the implanted component and the bone. The joint further includes a second prosthetic component of the prosthetic joint which, when implanted into an adjacent resected bone of the natural joint, articulates with the first component. A microporous membrane surrounds the first prosthetic component and is secured to the first prosthetic component and, when implanted in a body, is secured to bone surrounding said first prosthetic component, thereby sealing the junction against ingress of particles, but permitting liquids to pass through said membrane without restricting articulation of the joint.

An implantable orthopaedic knee prosthesis includes a femoral component that is configured to be coupled to a surgically-prepared distal femur. The femoral component has an articular side that includes a posterior femoral condyle surface. A fixation side is opposite the articular side, and it includes a posterior fixation surface that extends generally in the superior/inferior direction. The posterior fixation surface has an angled posterior cement pocket formed therein.
摘要:
A decorative column comprising a rigid center post, a plurality of pre-cast pieces with each piece having a hole extending therethrough so the pre-cast piece slides onto the center post and remains in place on the center post. Each pre-cast piece being stacked upon another pre-cast piece, the pre-cast pieces being of a predefined shape, and a compressible center core liner filling a portion of the hole of the pre-cast piece. The compressible center core including a cutout shape consistent with the cross sectional shape of the rigid center post thereby allowing passage of the center post through the compressible center core.

An articulated step system for an automotive vehicle includes a step housing attached to the vehicle frame by means of at least one standoff bracket and a tension strut extending generally downwardly from a first end attached to a vehicle body to a second end attached to the step housing. The articulated step has a stowed position generally underlying the body, and a deployed position extending generally outwardly from the body. Movement of the step may be either translational or rotational with respect to the step housing. In one embodiment, the step extends for the full length of the cab of the vehicle, and partially under a load carrying body at the rear of the vehicle.
摘要:
A rake with grasping heads for facilitating the collection of lawn debris. The rake with grasping heads includes an elongate inner rod being disposed in the interior of an outer housing. A first rake head extends from the bottom end of the outer housing and has a plurality of tines. A second rake head is pivotally coupled to a lower portion of the outer housing and has a plurality of uniformly spaced tines. The lower portion of the outer housing is rotatably coupled to the upper portion of the outer housing. The lower portion is rotatable between a first and a second position. The second rake head rotates with the lower portion of the outer housing. The second rake head is positioned behind the first rake head when the lower portion of the outer housing is in the first position. The second rake head faces the first rake head when the lower portion of the outer housing is in the second position. The second rake head is pivotable between an open position and a closed position. The second rake head is spaced apart from the first rake head when the second rake head is in the open position and is positioned towards the first rake head when the second rake head is in the closed position.
摘要:
A method of fitting orthopaedic prostheses is disclosed in which a semi-permeable microporous membrane is fitted over an implanted prosthesis so as to cover the junction between the prosthesis and the bone. In this way, particles generated by mechanical wear of the prosthesis are excluded. Such particles are believed to inhibit bone regeneration in the region of the prosthesis. In addition, by preventing the ingress of fibrous connective tissue cells, a secondary seal of new bone will form between the membrane and the original bone.
