Brannock Device shoe sizes of men, women, and children; they also produce specialized models for fitting other types of footwear. Brannock Device The Brannock Device is a measuring instrument invented by Charles F. Brannock for measuring a person's shoe size. The son of a shoe industry entrepreneur, Brannock attended Syracuse University, New York. Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, patenting his first prototype in 1925 and an improved version in 1927. The device has
Sizing agents such as acrylic co-polymers. Surface sizing agents are amphiphilic molecules, having both hydrophilic (water-loving) and hydrophobic (water-repelling) ends. The sizing agent adheres to substrate fibers and forms a film, with the hydrophilic tail facing the fiber and the hydrophobic tail facing outwards, resulting in a smooth finish that tends to be water-repellent. Sizing improves the surface strength, printability, and water resistance of the paper or material to which it is applied. In the sizing solution, optical brightening agents (OBA) may also be added to improve the opacity and whiteness of the paper or material surface. Internal sizing chemicals used
