Abstract: The libido of adult human female patients is increased by the bolus delivery of a testosterone which is preferably dihydrotestosterone. The formulation is preferably aerosolized and inhaled into a patient's lungs where particles of testosterone deposits on lung tissue and then enter the patient's circulatory system. The patient's testosterone level is quickly enhanced well above baseline levels for a short period and subsides to baseline levels with normal metabolism thereby providing desired short term effects on enhanced libido without undesirable effects of long term enhanced testosterone levels. Additional formulations are provided including formulations for aerosolized delivery of sildenafil citrate which are delivered to male or female patients.

Abstract: A method of forming a resist layer of uniform thickness across a surface patterned with a varying density of high aspect ratio features. A selected material layer having an affinity to a resist coat to be applied over the selected material layer is applied to a wafer having a plurality of recesses before applying a resist coat. After the resist coat is applied over the selected material layer, the selected material diffuses partially into the resist coat to condition a portion of the resist coat to be insoluble in the presence of a developer which is applied after the resist coat. Those portions of the resist coat into which the selected material layer has not diffused then are removed by a developer leaving a uniform resist coat thickness across the wafer.

Abstract: A pipe cleaner for manually cleaning the threads of pipes of differing sizes includes a body into which is slidably engaged at least one arm with an abrasive member. The abrasive member at the end of the arm extends into an orifice in the body. A single arm opposing a "V" shaped block may be used as well as a plurality of arms with abrasive members. A cover is rotatably mounted on the body and includes a number of angled slots, which are angled relative to radii of the cover and may be an arc segment of a spiral. Pegs that are coupled to each arm are engaged with the angled slot in the cover. Thus by rotating the cover relative to the body of the pipe cleaner, the arms with their abrasive members are driven inwards and outwards of the orifice by the peg and angled slot assembly. The cover includes an orifice that is approximately the same size as the orifice in the body, such that the cover does not inhibit a pipe from extending through the pipe cleaner.

Abstract: The absorbent structure of the invention has a substantially continuous absorbent web having an absorbent layer and a transfer layer. The transfer layer includes a nonabsorbent material and is capable of transferring liquids which it receives to the absorbent layer. The first and second edges of the absorbent web are coiled to form side walls, and the side walls form a trough therebetween. The top, trough-containing surface provides a natural trough in the space between the side walls for receiving and holding large gushes of body fluid until they can be absorbed by or dispersed into the rest of the structure.

Abstract: A process for the flame-retardant treatment of a cellulosic fabric by impregnating a fabric with an aqueous solution of a tetrakis (hydroxyorgano) phosphonium (THP) and then at least partially drying it. The partially dried impregnated fabric is passed at a speed of 30 to 100 m/minute once through a chamber containing ammonia for a single cure. Both the moisture contained in the fabric and water produced as a by-product of curing are volatilized and condensed on an interior wall of the chamber and flow down the walls to a drain for removal of the condensed water from the apparatus. The process further includes measuring the rate of ammonia in the gas fed into the chamber, determining the ammonia content of the gas and measuring the temperature within the chamber, for maintaining the initial concentration of ammonia in the gas at 70% to 90% by volume and for maintaining the ratio of ammonia input to the THP composition in the range of at least 1.

Abstract: A burner apparatus and method for reducing nitrogen oxides that are formed during combustion of gaseous fuel. Primary gaseous fuel and excess oxidant are premixed to form a fuel/oxidant mixture which is introduced into and combusted within a primary combustion zone. Primary combustion products are introduced into a secondary combustion zone. Secondary gaseous fuel is also introduced into the secondary combustion zone and is preferably mixed with the primary combustion products. The mixture of secondary gaseous fuel and primary combustion products is combusted in a secondary combustion zone. A portion of the secondary combustion products are internally recirculated into the secondary combustion zone. The overall combustion products can be externally recirculated and introduced into the primary combustion zone. A portion of the fuel/oxidant mixture, with or without the recirculated overall combustion products, can be bypassed around the primary combustion zone and introduced into the secondary combustion zone.

Abstract: The present invention provides improvements in absorbent products, but is particularly useful with urinary incontinence pads. An embossed pattern on the bottom layer of the double layer absorbent core construction improves the removal of urine or other fluids from the discharge zone to be ready for next void. One or more V-shaped notches cut at both ends of the pad provides the ergonomic fit of the pad to reduce the inevitable stiffness. The sides are designed as a flap which curves during the sealing process and provide natural curved flaps which form a soft gasket cushion and yields extra leak protection in the crotch area.

Abstract: An automated system for forming a taper on thin film magnetic heads comprises a lapping fixture positioned in apposition to a rotary lapping plate. A ceramic bar, upon which the magnetic heads are deposited and from which air bearing head sliders are fabricated, is attached to an adjustable transfer tool that is secured to a yoke holder. The holder is fixed securely on the lapping fixture so that the air bearing surface of the magnetic heads face the surface of the lapping plate. During the tapering process, data signals are obtained representative of the length of the taper being formed upon the heads spaced along the bar. The signals are calibrated and processed by a computer which provides command signals for varying the weight or pressure upon the lapping fixture across the fixture during tapering, allowing uniformity of taper to be achieved along with automatic termination of the tapering process upon obtaining the desired taper across the ceramic bar.

Abstract: An automated system for lapping thin film magnetic heads comprises a lapping fixture positioned in apposition to a rotary lapping plate. A ceramic bar, on which the magnetic heads are deposited and from which air bearing head sliders are fabricated, is attached to an adjustable transfer tool that is secured to a bow yoke holder. The holder is fixed securely on the lapping fixture so that the air bearing surface of the magnetic heads face the surface of the lapping plate. During the lapping process, digital data signals are obtained representative of throat height level of selected heads spaced along the bar. The signals are calibrated and processed by a computer which provides command signals for varying lapping pressure, changing direction of row bow, shifting a weight to achieve proportional lapping along the bar, changing the lapping process to a fine polishing step and forming tapers on the rails of the head sliders.

Abstract: An adjustable transfer tool is used to compensate for row bow during lapping a bar or a row of magnetic head sliders. The adjustable transfer tool enables establishing uniform and substantially precise throat heights for a multiplicity of thin film transducers disposed on said sliders. To allow the desired adjustment, the transfer tool incorporates slot means by which the shape of the surface of the tool on which the bar of sliders is mounted can be modified so that the slider transducers assume a collinear array across its entire length for the lapping process. Adjustment is accomplished by manual means, such as by a screw or a tapered pipe plug, or by electrical means, such as a piezoelectric actuator, in conjunction with a computer or microprocessor.
