Abstract: In a method for coating objects, a coating material is spread in or on a rotation body (6) as a film and is spun off from the edge (30) of the said body with the formation of electrostatically charged droplets. In order to disturb the even formation of droplets, at least one jet of air (10) acts partially on the film (31) which is still closed or already dividing. A device for carrying out the method has at least one air nozzle (11) which is directed onto a point within a droplet influencing zone (Z) which extends on both sides of the edge (30). In this way, a surface structure with a speckled effect is obtained when coating the object. <IMAGE>

Abstract: High molecular weight polyanhydrides, defined as polyanhydrides having a molecular weight average greater than 20,000 or an intrinsic viscosity of greater than 0.3 dl/g in an organic solvent at room temperature, are formed by melt polycondensation of highly pure isolated prepolymers under optimized reaction conditions, particularly time and temperature with removal of the condensation product. Higher molecular weights are obtained by inclusion of a catalyst with the prepolymers in the melt polymerization. Catalysts used for transterification, ring opening polymerization and related polymerizations may be utilized. 
     The high molecular weight polyanhydrides have improved physico-mechanical properties and are especially well suited for biomedical applications, particularly in controlled release devices for drug deliver.

Each button includes one or a pair of toothed pawls integrally hinged to a cross bar extending across a button aperture. The posts contain a series of transverse ratchets facing each other. As the second strip and its integral or snap-in latching button is manually pressed over the posts toward the first clamping strip, the teeth of the pawl teeth ratchet successively into the posts toward the base of the posts until the stack of paper is firmly grasped and the teeth mesh with a final transverse ratchet. At this position, the strips are bowed putting the edges of the stacked sheets in compression. A spine is also disclosed which has a series of parallel spaced score lines, and is bent around the edges of both clamping strips and firmly adhered to the strips. A simple tool to unlock the pawls is also disclosed. This allows substitute pages to be inserted into the stack and the same clamping strips to be manually reconnected.

Abstract: A controller for variably controlling the pacing rate of a cardiac pacer responsive to temperature which includes a logic and control unit, a parameter communication unit, an analog to digital converter and a temperature sensor. The temperature sensor in the right ventricle or atrium communicates a value related to blood temperature through the analog to digital converter to the logic and control unit. The logic and control unit operates under control of the rate algorithm to calculate a pacing rate value related to variations in the blood temperature. The pacing rate value is calculated as the sum of a reference rate, a natural rate response term, and a dynamic rate response term which contributes rate only in response to physical activity. A step rate response is also added to the calculated pacing rate when predetermined criteria related to the blood temperature and calculated pacing rate indicate the onset of physical activity. Under the control of the rate algorithm, the controller also maintains the level and rate of change of the calculated pacing rate within predetermined limits, and prevents the pacing rate from remaining at the maximum rate limit after physical activity has ceased.

Abstract: A system for localizing a diagnostic or therapeutic agent to an internal target site. The system includes (1) a biotinylated compound, (2) an avidin-­containing binding protein capable of localizing selectively at the target tissue, when administered parenterally, and (3) a clearing agent which can bind to and cross-link the binding protein, to form a protein ag­gregate which is readily cleared from the subject's bloodstream. In practicing the method of the invention, the binding protein is administered to the subject parenterally, and allowed to localize at the target site, typically within 1-4 days. This is followed by a chase with the clearing agent to remove circulating, but not target-localized binding protein. When the biotinylated compound is administered, binding of the compound to the localized binding protein, and rapid clearance of unbound compound by the kidneys, results in selective localization of the compound at the target site.
