On August 15, 1911, Ludmilla Kubelka of Vienna patented a new method to secure natural or artificial hair directly into hardening pulp. Using a small hooked tool, tufts of hair were pulled through the material and fixed on the inside, creating realistic, pore-like roots with a much stronger grip than glued-on wigs.

On October 10, 1934, Ludmilla Puettner of Vienna, Austria, patented a novel fastener made from two edging strips with matching loops. By laying one set of loops over the other and threading a ribbon through them in a braided path, the two strips are joined securely without the need for buttons or snaps, making garments easier to wash and iron.

On June 15, 1950, Ludmilla Staudinger of Vienna, Austria, patented a novel hand-knitting method for making double-face fabric with two threads. By pairing each loop into a knit and a purl stitch and crossing the threads in a set order, her technique produced smooth, fully reversible patterns.

On October 5, 1926, Luna H. Thralls of Hymera, Indiana, received a patent for an improved vanity case. Her invention enhanced the compactness of the item, incorporating space for a mirror, a card case, and a billfold.

On May 1, 1923, Mabel Blackman, a resident of Manhattan, New York, was awarded a patent for designing novel overshoes for horses. The invention aimed to increase road grip and reduce the likelihood of slipping on uneven surfaces.

On February 1, 1918, Mabel Slater, a resident of the United States, received a patent for a novel cover designed to be used as a bathrobe or military coat. The blanket was made from a soft and flexible material that quickly adapted to the body, aiming to keep it warm.

On July 5, 1932, Mabel White of Spokane, WA, was awarded a patent for her development of a novel and easily adjustable device designed to cut vegetables into cubes of different sizes.

On January 23, 1940, Mabel Winkel of New York was awarded a patent for designing a novel shoe made with an elastic-like leather upper sole that allowed for easy insertion of the foot.

On November 27, 1900, Mae Birney of New Whatcom, WA, received a patent for a novel jar closure featuring an improved flange lock designed to prevent liquids from leaking out.

On August 1, 1944, Maisie Jane Patterson of Chapel Hill, North Carolina, was granted a patent for a novel toe-protecting device. It featured soft fabric loops and padding to shield the toes from friction, corns, and calluses while keeping them comfortable inside shoes.
