Abstract: An electrotransport device (10) for transdermal delivery of an agent through a body surface has a donor reservoir (16) which contains a compound formed of the agent and a transdermal permeation enhancer, the compound being able to dissociate into an agent ion and an enhancer counter ion. Methods of enhancing transdermal electrotransport drug delivery and methods of forming a composition exhibiting enhanced transdermal electrotransport drug delivery are also provided.

Abstract: The invention measures the flow of a liquid by measuring the effect of that flow on a laser beam which travels from a laser source, through the flow, and landing upon a detector oriented to receive that laser source. Interfaces within the flow stream will refract the laser beam and cause variations in strength of the energy reaching the detector. These variations in the forward scatter occur at audio and super audio frequencies. The flow rate is proportional to audio frequency which can be measured and correlated by comparison to known flow rates.

Abstract: This facing surround assembly is provided which can be installed without fabrication in the field by anyone with average skills. The facing surround is generally made of non-combustible material and is generally used in conjunction with a fireplace or other wood burning appliance. The invention consists of two comer members, a horizontal header, two vertical support members attached together with the header located between the two corner blocks and the vertical support members being at right angles to the header, coplanar with the header and facing the same direction. The attachments are accomplished by adjustable members so that any one configuration of the invention can be used to construct a facing which could cover a number of different openings.
