Abstract: A cluster linkage parallel multi-channel rotational control device comprising two or more single channel rotational control devices operatively connected by a cluster linkage assembly to a central shaft. The central shaft is attached to a control input, for example, an aircraft control input. A housing surrounds the central shaft. Each single channel rotational control device is contained within and fixed to the housing. A bearing set supports the central shaft within the housing.

Abstract: Disclosed is a method for making oligomeric and polymeric isocyanates, particularly uretdiones and isocyanurates, by reacting diisocyanates in the presence of a catalyst, wherein the catalyst comprises either free N-heterocyclic carbenes, imidazolylidene carboxylates, triazolylidene carboxylates, or salts thereof.

Abstract: A deflator for monitoring and selectively or simultaneously deflating an inflated item, such as a basketball, includes a body configured with a central passageway, a first end, a second end and at least one side, each having a bore disposed so as to be in fluid communication with the central passageway. The deflator includes a measuring gauge for measuring the pressure of the inflated item and operationally secured to the body to be in fluid communication with the central passageway, an insertion needle for insertion into the inflated item, which is connected to the body and is in fluid communication with the central passageway, and a valve connected to the body portion, which is in fluid communication with the central passageway for selectively deflating the inflated item.
