Title: Adhesive for application of functional articles to the skin and comfortable removal of such articles
Inventor: COLES PETER
IPC: A61F13/15
Filed: 1997-12-22
Abstract: The present invention relates to topical adhesives for attachment to the skin.  In particular the present invention relates to such topical adhesives which can be employed for application of functional articles to the skin, particularly for the adhesion of functional articles or the improvement of the function of such articles. Functional articles in this context are cosmetic or pharmaceutical delivery articles which provide a substance to the skin such as skin treatment substances, creams, lotions, hormones, vitamins, deodorants, or drugs; alternatively cosmetic or pharmaceutical delivery articles can also provide a substance to emanate away from the skin such as insecticides, inhalation drugs, or perfumes; further the adhesive of the present invention can also be used in functional articles which are not attached to the skin but as a component in articles which require a high residence time on the skin such as decorative cosmetics (lipstick, eye colors, stage make-up) or cleaning articles (hand cleaner, face mask, hygienic cleanser especially for pores).  The topical adhesive provides secure attachment and is pleasing to the skin upon application, yet causes no discomfort and a low level of adhesive residues on the skin upon removal. This is achieved by selecting the chemical composition and rheological characteristics of the topical adhesives, in particular with reference to the relationship between the elastic modulus G' and the viscous modulus G'' of the topical adhesive.

Abstract: The invention relates to a heat exchange element (1) which is made up of a bag of a film material, such as plastic film, and to a heat exchanger made up of such heat exchange elements, the heat exchanger being suitable, for example, for the evaporation of effluents which contain solid matter, such as effluents from bleaching. The transfer of heat takes place in the bags (1) from a vapor condensing in the interior (3) of the bags to a liquid evaporating on their exterior surfaces (2). The forming evaporated vapor may be recycled via a compressor to the interior of the bags as heating vapor so that the heat exchanger will function as a distillation apparatus. According to the invention there is bonded inside the bag (1) a planar condensate-removal member, substantially narrower than the bag, for example, a circular disc (9) to which the forming condensate is arranged to flow and in which there is formed a hole (13) and at least one condensate outlet duct (8) leading to it, the film material of the bag being pierced in the area of the hole on each side of the condensate-removal member. In the heat exchanger, which has oppositely positioned bags (9) tied to form a pack, the condensate-removal members (9) are located one against another, and the apertures pierced in the film material form a condensate-collection duct common to them. The condensateremoval members being narrower than the bags enables the solid matter from the suspension being evaporated to be removed by falling through the spaces between the bottoms (10) of adjacent bags.

Abstract: For all domestic water closets (toilets) devices and methods to reduce water consumption focus upon reducing or restricting the available volume of water in the tank, but this reflects in a reduction of the designed performance of the water closet. Our invention serves to stimulate the water movement from tank to bowl during the flush process in order to maximize force and flow of the useable water and result in improving the efficiency of operation for the water closet.  Our invention inserts readily in the tank outlet where it meets the bowl just below the tank flapper and is also as easily removed.    The blade assembly is powered by the water which is evacuated downward from the tank and then powers the water horizontally through the bowl ring. The design of the blade assembly increases the mechanical advantage which effectively increases the horizontal power of the blade assembly beyond the vertical power neccessary to turn the blade assembly. The result sees our invention deliver a set volume of water faster than the usual gravity flow.

Abstract: A probe type instrument to characterize tissue type that combines optical and electrical tests in a single device capable of providing data of both types almost simultaneously from very small, e.g. 3-10 mm diameter, areas of tissue surface. Key to this approach is an instrument capable of making almost simultaneous electrical and optical measurements on the same small areas of tissue, before being moved to scan adjacent tissue areas. In the preferred operation of the system fourteen measurement cycles are performed per second and each measurement involves a complex sequence of events, including (1) three optical and fifteen electrical tissue stimulations with subsequent detection, filtering and digitization of the tissue response; (2) extraction of specific parameters from the optical and electrical signals; (3) checking for errors, and subsequent classification of the extracted parameters into various tissue type categories; and (4) feedback to the system operator. Thus on the order of 15,000 measurements are made per one minute patient examination.
