    摘要: Microwave absorbers reduce radar cross-sections of airborne objects by attenuating reflectivity values. In Jaumann absorbers laminated layers are placed on the reflecting surfaces, the laminated layers being lossy layers separated by dielectric spacing layers. From the point of view of accuracy and reproducibility Jaumann absorbers have been difficult to construct. A mode of fabrication overcoming these difficulties is provided herein.

    摘要: A sporting net which can be utilized either as a hockey net or a basketball hoop. The apparatus includes a center post having a basketball hoop and its upper end. Furthermore, two linkages are pivotally secured at opposing locations at the intermediate extent of the center post. A hockey net is secured in between these two linkages. In order to facilitate storage of the sporting net, the linkages are pivotal between a first use orientation, wherein they extend laterally from the post then downwardly to abut a recipient surface and a second storage orientation wherein they are positioned generally next to the post.

    摘要: A protein which inhibits collagen-stimulated platelet aggregation. The protein has a molecular weight of approximately 17,000. A method of isolating the protein from Ornithodoros moubata and using the protein to prevent or delay blood coagulation by blocking the stimulation of platelet aggregation by collagen is also described. The protein is useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.
