Abstract: A set of cams for actuating the lowering sinkers in circular knitting machines, for producing standard-terry knitting and sandwich-terry knitting. The cam set comprises cams and countercams which form a path for the heels of the lowering sinkers which have two lowering planes arranged at mutually different elevations for at least two yarns which are dispensed at a feed of the machine to form loops of terry knitting. The cam set also comprises, in the region of the path that corresponds to the descent of the needles of the needle cylinder to form loops of knitting with the two yarns dispensed at a feed of the machine, a cam which can move on command into two operating positions in order to produce at least one variation of the path formed by the cams and countercams.

Abstract: A fastener for a shin guard mounted on the leg of an athlete including upper and lower bands connected at their ends by diagonal bands, fork bands connecting the outer ends of the upper and lower bands to each other, a band of pile fabric extending outwardly from one of the fork bands, and a band of hook fabric extending outwardly from the other of the fork bands. A combined shin guard and fastener wherein the upper and lower bands are secured to the shin cover.

Abstract: A method for measuring the concentration of adhesive on the surface of a coating layer which has the steps of irradiating the surface of the coating layer with an ultraviolet ray of the highest peak absorption wavelength of the adhesive, ultraviolet ray of shorter wavelength and ultraviolet ray of longer wavelength, photoelectrically converting the reflected rays and further comparing to calculate them. Thus, this method can be used to measure the concentration of adhesive on the surface of a coating layer and the flat surface distribution of the adhesive by fundamentally measuring with ultraviolet rays. The method is of high reliability despite the presence of gloss or the like.
