Title: Machine for rewinding and intermediately processing thin flexible material using a conveyor
Inventor: MEMBRINO HERCULES
IPC: B65H20/02
Filed: 1992-10-16
Abstract: Abstract of the Disclosure An apparatus and method is provided for processing and rewinding a web made of easily stretchably deformable plastic film.  The web is drawn from a supply roll assembly by a series of synchronously, positively driven draw and transfer rolls and directly delivered to a rewind spindle.  The rewind spindle is positively driven at a speed greater than the speed imparted to the web by the draw and transfer rolls.  However, the rewind spindle is in peripheral contact with a transfer drum which is the last of the series of draw and transfer rolls so that the processed web is immediately transferred from the transfer drum to the rewind spindle.  The transfer drum exerts a drag on the rewind spindle to control and match the speed of the rewind spindle to the speed of the moving web.

Title: Branched polyanhydrides
Inventor: DOMB ABRAHAM J
IPC: A61L27/00
Filed: 1991-06-04
Abstract: Branched polyanhydrides that have superior pro-perties for use in the controlled delivery of substances, prepared by the polymerization of a dicarboxylic acid monomer and a branching agent. The branching agent is a polycarboxylic acid monomer such as 1,3,5-benzen-etricarboxylic acid ("BTC"), or an oligomerized fatty acid trimer. Alternatively, the branching agent is a poly-carboxylic acid polymer such as poly(acrylic acid) ("PAA"). These branched polymers have significantly higher molecular weights and lower specific viscosity than linear polymers prepared under similar conditions.    A major advantage of branched polyanhydrides is that the degradation and release kinetics can be substantial-ly altered without significantly changing the physical properties of the polymer relative to the corresponding linear polymer. By manipulating both the diacid and the branching agent, a wide variety of biodegradable controlled delivery devices for diverse applications can be prepared.

Title: Condensate Drain Controller
Inventor: PICCIRILLO DAVID P
IPC: F28G15/00
Filed: 1993-07-23
Abstract: A system for automatically controlling a drain valve connected to a sootblower steam piping system utilizes two temperature measurements, one near the steam source and the other near the drain valve.  Comparison of the difference in steam temperature between these two locations with an adjustable temperature setpoint allows the drain valve to be opened to drain condensate and maintain minimum allowable superheat over a wide range of conditions.  The system allows the temperature sensing to "float" with steam source conditions, since it is continuously adjusted to compensate for steam source temperature and ambient temperature changes.
