The brassiere frame also includes a body band adjacent the lower edge of the frame and connected to the pair of breast cups and the pair of dorsal panels, and a horizontally stretchable, triangular member positioned between the lower portion and a part of the upper portions of the breast cups for connecting together the breast cups and also connected to the body band.

Abstract: A plastic support which has a substantially U-shape configuration and has a base portion and a pair of end portions with the base portion and the end portions having a different cross-sectional configuration. The plastic support also has a pair of regions positioned between the base portion and a different one of the pair of end portions, and in a preferred embodiment the pair of regions is a pair of intermediate portions each having a cross-sectional configuration different than that of the base portion and the pair of end portions. The plastic support is, preferably, made of a mixture of reinforced acetal rein and nonreinforced acetal resin, and exhibits unexpected "creep" properties such that the end portions thereof are closer together after machine laundering at a normal cycle than their initial condition.

Abstract: There is provided a brassiere frame for use in conjunction with breastcup supports. The brassiere frame includes a front portion, a pair of side panels made of a substantially elastic material, and a pair of breast cups each adjacent the front portion and a different one of the pair of side panels. Each breast cup has an almost perfect U shape configuration and each side panel has a particular pitch so that the brassiere frame provides that breast supporting forces are directed at the base of the breast cups thereby anchoring the brassiere frame and the remaining component forces are transmitted substantially in only one direction.

Abstract: A voided polypropylene film tampon wrap having end seals which are formed by mechanical crimping and a process for sealing the ends of the voided polypropylene film tampon wrap by mechanical crimping. A notch is formed adjacent to each end seal but remote from the enclosed tampon. Each end seal is formed by a pair of horizontal teeth wheels each having a pitch of 50 teeth per inch. One of the pair of wheels is heated to a temperature of 125.degree..+-.15.degree., and force is applied to at least one wheel to seal that end of the wrap by the pair of wheels.

Abstract: Method for increasing the absorbency of cellulosic fibers by a high temperature wet treatment comprising heating the fibers in a water bath at temperatures within the range of about 95.degree. C. to 100.degree. C. for periods ranging from about one to sixty minutes. Absorbency of the treated fibers is thus increased by more than 2% of the corresponding untreated fibers as measured by the Syngyna Test Method. By employing such materials in catamenial tampons, sanitary napkins or the like, the amount of absorbent material may be decreased by 10% or more relative to the corresponding, untreated absorbent material, without adversely affecting the absorbent characteristics thereof.

Abstract: A plastic support which has a substantially U-shape configuration and has a base portion and a pair of end portions with the base portion and the end portions having a different cross-sectional configuration. The plastic support also has a pair of regions positioned between the base portion and a different one of the pair of end portions, and in a preferred embodiment the pair of regions is a pair of intermediate portions each having a cross-sectional configuration different than that of the base portion and the pair of end portions. The plastic support is, preferably, made of a mixture of reinforced acetal resin and nonreinforced acetal resin, and exhibits unexpected "creep" properties such that the end portions thereof are closer together after machine laundering at a normal cycle than their initial condition.

Abstract: A molded brassiere formed of a thin fabric includes a nipple patch or cover smoothly adhered to an apex portion of each breast cup to impart a pleasing and modest appearance. The nipple patch is sized, shaped and of an opacity to comfortably cover the nipples and surrounding areola. Further, the nipple patch is sufficiently rigid to depress the nipples, which might otherwise protrude through the thin cup fabric and, thereby, provide a smooth contour along the natural arc line of the bust.The method of making the breast cup of the brassiere is easily and simply accomplished by juxaposedly positioning a coated patch fabric onto a central portion of the flat cup fabric and simultaneously adhering and molding the fabrics at preselected temperatures to form an unitary, three dimensional breast cup including the nipple patch.

Abstract: A method of preparing a spun yarn for use in a fine gauge wrap knitting machine having the following steps: (a) spinning polyester stable fibers having a denier of less than 2 and having a staple length in a range of about 1.5 to about 2.0 inches, (b) twisting the yarn in a range of 24 to 36 twists per inch, (c) waxing and steaming the yarn, and (d) warping the yarn in an environment having a humidity in a range of 65% to 70% and having a temperature in a range of 70.degree. to 72.degree. Fahrenheit.

Abstract: A method of making an improved seat assembly for a butterfly valve. The seat assembly comprises a flexible, circular metal band embedded in a resilient material to form an annular seat assembly. The assembly is made by supporting the band in a fixed spatial position on movable finger members, positioning a mold about, but spaced from, the band, and molding the annular seat assembly in the mold to embed the band. The invention is also directed toward an improved seat assembly. In a preferred embodiment the circular band is made of two curved sections overlapping at the two joints and having diametrically opposite holes in the two overlapping areas.

Abstract: A bi-directional valve sealing means for location in a chamber formed by diverging juxtaposed surfaces on the valve body and the retaining means removably affixed to the valve body. The sealing means extends into the passage through the valve body for rotation about a point in the chamber, the sealing means becoming wedged into fluid-tight contact with the valve closure means when the valve closure means is rotated to block the flow of fluid through the valve passage.

Abstract: A toy vehicle is provided for use in a toy vehicle game including an endless track defining at least two parallely extending vehicle lanes in which two or more toy vehicles are adapted to be operated. The toy vehicles each include a reversible electric rotary drive motor and a transmission operatively engaged between the motor and the drive wheels for driving the vehicles in a forward direction regardless of the direction of rotation of the drive motor. The vehicle includes steering wheels and a second transmission connected between the motor and the steering wheels to rotate the steering wheels between their right and left hand driving positions in response to a reversal of the polarity of current supplied to the motor thereby to bias the car against one or the other of the side walls of the track to guide the vehicles along their path of travel in one or the other of the lanes.
