Abstract: Pressurized web treatment systems include a moving web that passes through a pressurized treatment chamber having a sealing assembly with a leakage control system. Leakage control is achieved by the cooperative effect of localized leak detectors and leak reduction means that applies a local sealing force on the seal assembly responsive to a signal from the leak detectors such that increased sealing occurs in the vicinity of the leak. In particular, an air press for paper web dewatering has improved efficiency by virtue of the leakage control system, which features local leak detectors and local force generation means associated with a flexible seal assembly to reduce leakage at the edges of the stationary plenum of the air press. Local leak detection can be based on sonic measurement with microphones, detection of escaping tracer gas, optical signals, and other means.

Abstract: Disclosed herein is a water dispersible pantiliner which has a triggerably dispersible body side facing liner, a garment side facing baffle, and, optionally, a triggerably dispersible absorbent core disposed between the liner and baffle. The garment baffle may be biodegradable. In one embodiment, the invention has a peel strip overlaying a garment attachment adhesive layer which adhesively attaches the peel strip to the clothing of a wearer on one side and to one side of a baffle on the other. The baffle is in turn attached on a second side to a body facing side with a construction adhesive. The body facing side may be made from multiple layers such as a body side liner and absorbent layer.

Abstract: The present invention provides a child's disposable absorbent training pant having an improved waist elastic system. The waist elastic system has a selected maximum magnitude of decay over the first three cycles at a specific extension, thereby providing a substantially uniform low tension over a wide size range, a more comfortable fit, and improved ease of use.

Abstract: The present invention relates to a process for the synthesis of a linear phosphonitrilic chloride LPNC catalyst solution in a siloxane medium. The process involves mixing phosphorus pentachloride with a suitable silazane followed by warming the reaction mixture to yield a LPNC catalyst solution.

Abstract: The present invention relates to a process for the synthesis of a linear phosphonitrilic chloride (LPNC) catalyst solution. The process involves mixing phosphorus pentachloride with a suitable silazane in a methylene chloride medium. The methylene chloride is then replaced with a siloxane medium followed by heating this mixture to form a LPNC catalyst solution.

Abstract: A disposable absorbent article includes a waste containment assembly that has a liner, outer cover, and an absorbent between the liner and outer cover, and a pair of containment flaps that are operatively joined in a foreshortened state to the waste containment assembly. Methods are provided for making the absorbent article.

Abstract: A digital rotating complex phasor generator (60) provides a constant magnitude continuous phase signal at either a positive or a negative frequency for translating the frequencies of a modulated signal from a near-zero intermediate frequency (IF) to baseband. The rotating complex phasor generator allows a digital receiver front-end to down-convert the received signal to an IF of substantially zero Hertz prior to analog to digital conversion, even in the presence of large Doppler frequency shifts and tuning uncertainties which may result in a residual IF carrier which has either a positive or a negative frequency.

Abstract: A toilet training aid is in the form of a pad that creates a noticeable, distinct feeling during urination. In particular embodiments, the pad may provide the wearer with a temperature change sensation, a wet sensation, a dimensional change sensation, or some combination thereof to signal that urination is occurring. The toilet training aids are desirably attached to a garment by a consumer, thus enabling the consumer to select the type of accompanying garment and the particular time that is best suited to toilet training.

Abstract: To adapt a punch press to cut work blanks, a cutting mechanism having a freely rotating cutting wheel is provided to a first support of the punch press while a corresponding die having a groove for mating with the cutting wheel is provided to a second support of the punch press. To operate, the cutting wheel is moved toward the die a given distance such that the cutting edge of the cutting wheel slidably mates with the cutting edge of the groove of the die to effect cutting of the workpiece. By synchronously rotating both the cutting wheel and the die to different orientations while maintaining their respective cutting edges aligned and in sliding contact with each other, by moving a worksheet relative to the cutter wheel and die, a multidirectional cut path may be effected on the worksheet.

Abstract: The reaction of phosphorus pentachloride with ammonium chloride is conducted in the presence of a metal-containing catalyst and carbon dioxide, preferably supercritical carbon dioxide, as a solvent. The product is generally superior in catalytic action for the polycondensation and rearrangement of organosiloxanes to conventional linear phosphonitrilic chlorides.

Abstract: A process for making disposable absorbent articles including continuously moving a first layer in a first direction and a second layer in a second direction, continuously providing elongate elastic members to the first layer and to the second layer, folding the layers over the elongate elastic members, joining the elongate elastic members to the layers to form first and second continuous elastic composites, continuously moving a base layer having opposite edge portions, continuously delivering the first and the second continuous elastic composites to respective edge portions of the base layer, joining the first and the second continuous elastic composites to the edge portions of the base layer, providing a plurality of spaced apart absorbent structures on the base layer, folding the continuously moving base layer, bonding the folded base layer between the absorbent structures, and cutting the folded base layer to form a plurality of disposable absorbent articles.

Abstract: Organopolysiloxane oils and gums are produced by the condensation of silanol-terminated organosiloxane in the presence of an effective amount of a peralkylated phosphazene base as a catalyst and at reduced pressure.

Abstract: The present invention provides a child's disposable absorbent training pant having an improved waist elastic system. The waist elastic system has a selected average maximum rate of change of modulus of elasticity over the first three cycles within a specified extension range, thereby providing a substantially uniform low tension over a wide size range, a more comfortable fit, and improved ease of use.

Abstract: The invention relates to melt-miscible polyolefin blends, and a process for preparing the melt-miscible blends, of two or more polyolefins. Matching of the segment length of a modifying polyolefin with the segment length of a primary polyolefin, such as polypropylene or an ethylene/alpha-olefin copolymer, provides polyolefin blends heretofore unknown to be melt-miscible. A broad range of polyolefin blend compositions, and of polyolefin blends containing other polymers made compatible with the polyolefin blend compositions, are defined, all of the blend compositions having at least one melt-miscible polyolefin phase.
