Abstract: Disclosed is a method for producing an intra-oral dental bandage membrane and/or therapeutic membrane containing therapeutic agent. Actinic light is used to polymerize the membrane composition material to fix the composition in position locked with rigid dental structure such as teeth. The polymerizable substance is manipulated and shaped in a fluid state and then set, as shaped very rapidly in situ. Also disclosed is a new treatment membrane that in a preferred form is a non-symetrical oligomer that is a urethane polyacrylate.

Abstract: A garment with a backsheet (12), a bodyside liner (14) essentially coterminous with the backsheet (12) and forming a shape with a front waist section (18), a back waist section (20) and side sections connecting the front waist section (18) to the back waist section (20) and first and second flaps (30, 32) formed from or attached to bodyside liner (14). Flaps (30, 32) may have elastic members (40, 42) applied thereto respectively. Flaps (30, 32) may be folded inwardly and respective ends thereof may be bonded to bodyside liner (14) so that edges of flaps are directed toward a centerline (38) of the garment. The flaps (30, 32) may be attached to or formed from bodyside liner (14) along lines (34, 36) which are parallel to centerline (38) or which diverge from or converge toward centerline (38). Additionally, flaps (30, 32) may have varying width and be less than full length.

Abstract: A hydrophilic article is disclosed which is a layer of a non-cross-linked copolymer of a hydrophobic monomer component and a hydrophilic monomer component. Preferred hydrophobic monomers are lower alkyl esters of methacrylic and acrylic acids and preferred hydrophilic monomers are vinyl pyrrolidone and hydroxy ethyl methacrylates. The hydrophilic articles of the invention are useful in biomedical applications, especially in wound dressings and as coatings on catheters.

Abstract: Absorbent articles containing both an acidic buffering agent and a non-toxic, non-irritating, non-volatile antimicrobial agent are disclosed. The acidic buffering agent is preferably also an absorbent gelling agent which can imbibe aqueous body fluids in addition to acting as a buffer. Such articles are especially suitable for maintaining the pH of urine and feces discharged into the article at value below about 7.5. This in turn helps to prevent or reduce diaper rash and control odor caused by the production of ammonia.

The method comprises the steps of: (a) contacting the mammal's immune system with the specific antigen for a suitable time period so as to artificially stimulate said immune system; (b) withdrawing blood cell containing material, including antigen stimulated blood cells, from the mammal; (c) treating the withdrawn material or cells so as to alter the stimulated cells; and (d) returning the material and treated cells to the mammal.

Abstract: The mouth moisturizing pad for treatment of an individual suffering from xerostomia comprises at least two approximately oval shaped sponge sections saturated with water and of a size such that when placed adjacent each other the sponge sections just fit in a cheek pouch of the individual being treated and an envelope or covering made of knit cotton cloth in which the sponge sections are held. The method of treatment which is even effective during sleep thus alleviating associated frequent wakefulness comprises saturating the mouth moisturizing pad with water and inserting it in the cheek pouch of the individual where it remains because of the critically chosen dimensions.

Abstract: A method is disclosed for nuclear magnetic resonance imaging wherein the improvement is the use of perfluoro 15-crown-5 ether which has 20 magnetically similar fluorine atoms providing a superior signal to noise ratio with resultant enhanced diagnostic resolution.

Abstract: A stretchable, knitted, panty-type holder for disposable or reuseable absorbent wound dressings or pads for babies or adults has a generally hour-glass shape with a back waistband portion and front waistband portion. The front waistband portion has at least one opening formed in each end thereof, and the back waistband portion has at least one ribbed or enlarged portion formed near the ends thereof. When applied to the body of a patient with an absorbent pad placed therein, the back waistband portion, which has a free end extending beyond the enlargements therein, is brought around the waist and passed through the opening in the adjacent end of the front waistband portion until the enlargement is secured adjacent the opening, whereupon the free end of the back waistband portion is tucked inside the holder between the body of the patient and the inside of the holder.

Abstract: Disposable garments such as disposable diapers are disclosed that possess improved elastic characteristics. At least one garment outer sheet is composed of a drawable fabric, such as melt blown polymeric fibers or melt spun filaments. An elastic element is affixed in the relaxed condition to a web of outer sheet fabric. The elastic web is then stetched, and simultaneously the web in the area of elastic element attachment is drawn to impart a molecular orientation to the web fibers. As a result, the web fibers are permanently elongated. Upon relaxation of the stretched elastic element, shirrs or gathers are formed in the web fibers that permit subsequent stretching of the elastic element when the garment is worn. One of the outside sheet webs need not be drawable or drawn if it is preformed with corrugations or pleats in the region of elastic element attachment. The present invention also includes apparatus for manufacturing the garment.

Abstract: The invention provides a dispenser form for substainedly releasing vapor of a sex pheromone compound of pest insects with an object to control the population of the insects. The invention dispenser is characterized by the features that: the capacity thereof is sufficiently large to contain at least 100 mg of the pheromone; the barrier wall thereof through which the pheromone permeates to be released from the outer surface is made of a polymeric material swellable with the pheromone in an equilibrium swelling of 2-6% by weight at 20.degree. C.; and the outer surface area S thereof given in mm.sup.2 is sufficient to give a ratio S/W, W being the amount of the pheromone contained therein given in mg, in the range from 4 to 11. The rate of pheromone emission from the dispenser is relatively constant at 0.6 mg/day or larger over a long period of time of, for example, 3 months or longer.

Abstract: A distinctive absorbent article includes a backsheet layer and an absorbent body superposed in adjacent, facing relation with the backsheet layer. An actuating member connects to the article in liquid communication with the absorbent body and is composed of a liquid-contractible material. The liquid-contractible material is capable of shrinking upon contact with an aqueous liquid while maintaining a substantially unitary configuration. An indicating mechanism is connected to the actuating member for designating a wetness condition of the absorbent body, and is translatable along a selected path in response to the shrinkage of the actuating member.

Abstract: A diaper for a dog or other small quadruped comprises a textile body band and tail band forming a T with fasteners at one or both ends of the body band and the end of the tail band and an absorbent pad affixed to the inside surface of the tail band at its junction with the body band. The body band is wrapped around the dog's body with its ends on its back and those ends are connected by their fasteners. The tail band is brought over its rump and back and fastened to the body band ends at their junction so that the absorbent pad is against the dog's genital and anal areas. The tail band may be unitary with an opening for the dog's tail, or bifurcated.

Abstract: A carrier strip or filament of cold drawable material is utilized to transport discrete lengths of elastic ribbon within a manufacturing apparatus. The elastic ribbons are extruded onto the carrier strip or around the filament and adhere thereto. The carrier strip and elastic ribbon are jointly stretched a predetermined amount. The stretched carrier strip and stretched elastic ribbon are bonded to a component of a final product, as, for example, the backing sheet of a disposable diaper, wherein the elastic ribbons are employed to elasticize the leg areas. The carrier strips greatly facilitate machine handling relatively short lengths of stretched elastic ribbons without waste. The carrier strips may be transversely guided along a predetermined path to follow the hourglass contour of the margins of a diaper having form fitting legs.
