    Abstract: An enhanced system and method for executing options trades are disclosed. The lead market maker entitlements are integrated with sophisticated order types, including dark order types, so that the lead marker maker is guaranteed an allocation of the trade if the lead market maker is at the NBBO when an order priced at or better than the NBBO is received. The lead market maker is not provided an opportunity to price improve to execute with a specific incoming order. Additionally, market makers who are not the lead market maker in an option series may be granted the privileges of a lead market maker for the purpose of executing with a specific incoming directed order if the designated market maker is at the NBBO when a directed order priced at or better than the NBBO is received. The system and method disclosed encourages market makers to quote the best price possible, which in turn has the effect of narrowing spreads. Furthermore, as only displayed orders at the NBBO are eligible to execute ahead of market makers quoting at the NBBO, the system and method encourages users to display their best prices and sizes to the marketplace.

    Abstract: Modular support systems for supporting multi story buildings including plates having bottom major faces and top major faces, the plates defining bolt holes extending through the plates, vertical columns extending from bottom ends to top ends opposite the bottom ends, the bottom ends of the vertical columns being welded to the top major faces of the plates, and horizontal columns having bottom sides and top sides opposite the bottom sides, the bottom sides of the horizontal columns being welded to the top end of the vertical columns. In some examples, the horizontal column defines bolt holes being positioned to align with the bolt holes defined in the plate. Some examples include pluralities of structural units selectively fastened together in a vertical arrangement, with each structural unit configured to selectively couple with vertically adjacent structural unit. Some examples define buildings including disclosed support systems.

    Abstract: A hydraulic bolt tensioner has a reduced height by virtue of inner seals between a cylinder and piston being aligned along a same plane. The tensioner also has a reduced width by virtue of carbon fiber would about the tensioner's housing, reducing the need for a certain thickness of material used for the tensioner's housing.

    Abstract translation: 液压螺栓张紧器由于气缸和活塞之间的内部密封沿同一平面对准而具有减小的高度。 张紧器还通过碳纤维围绕张紧器的外壳而具有减小的宽度,减少了用于张紧器壳体的一定厚度的材料的需要。
