A mounting structure including at least one display board including a first mounting interface and a second mounting interface, a first pivotal interface including a first projection forming a retaining slot adapted to engage the first mounting interface of the display board wherein the first projection is a hook and the second pivotal interface adapted to engage the second mounting interface of the display board so that the display board is adapted to be removably pivotally coupled to the mounting structure at both the first pivotal interface and the second pivotal interface.
摘要:
A mounting structure for at least one display board is disclosed. The Display board includes a first mounting interface and a second mounting interface. The mounting structure includes a first pivotal interface including a barb adapted to engage the first mounting interface of the display board. The mounting structure also includes a second pivotal interface including a protruding member adapted to engage the second mounting interface of the display board. The display board may be removably pivotally mounted within the mounting structure at the first pivotal interface and the second pivotal interface. A mounting structure for display of at least one display board is also disclosed. The mounting structure includes a frame. The mounting structure also includes a platform for the display board coupled to the frame. The mounting structure also includes a compliant retaining system for the display board coupled to the frame. The display board can be placed on the platform and pressed into secure engagement with the compliant retaining system. A mounting structure associated with an existing structure and for use with at least one display board is also disclosed. The mounting structure includes an articulating frame pivotally coupled to the existing structure for movement between a fully deployed position and a fully stowed position. The mounting structure also includes at least one display rack coupled to the articulating frame and providing a first and second interface for pivotal coupling of a plurality of display boards.
摘要:
A process is provided for the isolation of two protein fractions herein termed the "blocking protein fractions" or "Blocker I" and "Blocker II," from mammalian blood. The process comprises a series of centrifugal separations of blood fractions under conditions which maintain the integrity of the desired material as it existed in vivo. These blocking protein fractions are new materials and they constitute another aspect of the invention. Isolated Blocker I and Blocker II, which are natural proteins or derivatives thereof, are useful to prevent tissue implant rejection, and as standards for the determination of the tumor remission activity of other materials isolated from blood.
