Abstract: A bristle shaft device for use in disinfecting subgingival parodontal pockets, parodontal pocket edges and tooth surfaces, the device having a rotationally symmetrical gingival edge cup having an axis and an external periphery and a plurality of coaxial bristle shafts arranged coaxially in a ring and held in position by the cup. The shafts project from the external periphery and are formed as individual radially adjacent layers. One of the layers extend beyond the other layers so as to have an exposed end and can penetrate into a subgingival parodontal pocket up to a ligamentum circulare. Another layer adjacent to the one layer resists a bending of the exposed layer. The remaining layers are formed as multiple stepped layers that drop off in steps from each other in a radially outward direction providing further reinforcement. The one layer is radially innermost of the rest of the layers. Both the one layer and the adjacent another layer project beyond the remaining layers.

Abstract: An electrical air heater for a calender roll diameter control device is described. The heater comprises a tube for directing a flow of air along the inside of the tube from a plenum toward an object which is to be heated. An electrically resistive heating element is mounted inside the tube to heat the flow of air as it flows from the rear to the front of the tube. Since the air is heated by the heating element inside the tube, the air is coolest when it first enters the tube and hottest where it escapes at the front of the tube. Similarly, the heating element is cooled by the air and is, therefore, hottest near the front of the tube where the heated air escapes. The hotter front end of the heating element tends to burn out faster than the cooler end of the heating element. To prolong the life of the heater, openings are provided in the tube wall to admit a flow of cooling air at the hottest part of the heating element.

Abstract: The invention relates to a method for accomplishing smoothness and glaze to paper or board webs in a calender by leading a web through hot nips which are formed between cooperating rolls of different hardnesses and having adjustable temperatures, and where a gradient calendering of the web based on the temperature difference between the web and the rolls is brought about. In order to increase the efficiency of the gradient calendering and in order to achieve a suitable temperature difference between the web and the heated rolls, the temperature of the web is arranged to be adjustable before the web enters the hot nip.

Abstract: This application relates generally to animal tooth brushes specifically designed for cleaning the teeth of animals whose teeth and mouth shape is different from human, and whose gums are more sensitive.

Abstract: The present invention provides an improved brush for cleaning underwater surfaces, such as swimming pool walls and bottoms, and uses a hinged wing that presents an inclined plane to the water when the brush is moved in its downward stroke. The wing thus acts to exert a desired force upon the brush which urges the brush against the surface being cleaned. On the return stroke of the brush, the hinged wing is caused to move to a position trailing the brush, where it avoids urging the brush back into contact with the surface that was just cleaned on the downward stroke. Rather, this trailing position helps to keep the brush off of the cleaned surface, and creates little or no drag for the return stroke.

Abstract: This invention relates to a hairbrush that comprises bristles or bunches of bristles arranged in parallel rows. The length of the bristles in each row differs from row to row in the direction in which the brush is moved through the hair of a person whose hair is being brushed so as to have the row of longest bristles lift or fluff each successive increment of hair it engages and have the successive rows of successively shorter bristles smooth down each successive increment of hair that has been lifted by the longer bristles in the previous rows that engage the hair.
