High strength polymers and aerospace sealants therefrom

A blend of multimodal average molecular weight sulfur or ether linkage containing organic polymers provides sealants, potting compounds and moldable compositions with good physical properties. In the case of S-containing polythioether or polysulfide, these properties are well suited to the formulation of aerospace sealants even using standard lightweight filler technology. Sealants based upon this multimodal blend concept exhibit improved strength and toughness even when relatively large amounts of lightweight fillers are used. Multimodal polyurethanes and other ether linkage containing polymers also show enhanced physical properties.

A core biopsy guide that is removably secured to the finger of a gloved hand to position a core biopsy needle sampling device adjacent the tissue of the organ to be sampled. The biopsy guide comprises an elongated tubular open-ended sleeve portion and a funnel portion in communication therewith. The biopsy guide provides a rigid path for a spring driven core biopsy needle device to be positioned therethrough engaging the target tissue to be biopsied.

An eccentric indicator in combination with a compound bow the compound bow has rotatable eccentric wheels at the ends of the bow limbs, around which cables forming part of the bowstring are trained. The indicator comprises a pair of rotatable indicator wheels mounted above and below a simulated arrow shaft, about three-quarters of the distance back from the front end thereof. Flexible cords pass around pulleys mounted on the sides of the indicator wheels, and one cord is attached at one end of the bowstring close to the upper eccentric wheel, while the other cord is attached at one end to the bowstring close to the lower eccentric wheel. The other ends of the cords are attached to elastic cords, which are fastened to the front end of the shaft. When the device is used in place of an arrow and the bow is drawn, the indicator wheels are turned by the cords as the latter are pulled by the elastic cords to take up slack due to rotation of the eccentric wheels. If the eccentric wheels are turning in synchronism, the indicator wheels will rotate as though geared together. If the indicator wheels rotate at different rates, it is an indication that adjustment of the bow is necessary. The two indicator wheels, being located close together and in the archer's line of sight, enable him to see simultaneously the relative rates of rotation of the eccentric wheels on the ends of the bow.
