Abstract: The thread testing apparatus of a textile spooling machine is equipped with a thread inserter which is responsive to knots formed in the thread. In a typical thread testing apparatus a flaw is detected in a fault sensing zone whereupon the thread is cut, the flaw is removed and the loose ends of the good thread are reunited with a knot. Due to the nature of the sensing mechanism, it is not desirable to place the reunited thread back in the fault sensing zone until the thread starts moving again. The thread inserter of the present invention accomplishes this function by detecting the presence of the reuniting knot with a slot having a width smaller than the knot, but larger than the average width of the thread. The thread inserter also includes a slough off means for guiding the thread back to the falt sensing zone and a magnetic means for biasing the thread inserter in a first knot detecting position.

Abstract: The invention relates to a filter fabric, particularly of single-strand metal- or plastics filaments, in which one system of the two intersecting systems of filaments consists of filaments of thicker, mutually equidistantly spaced filaments extending in a straight line and the other system of thinner, sinusoidal filaments which are mutually juxtaposed as closely as possible and which embrace the thicker filaments and in which the filter gauge is determined by the diameter .mu. of the largest measuring sphere which passes through the apertures in the triangular pores of the fabric which are each formed by a thicker filament and two adjacent, phase-displaced, thinner filaments. The expression "filaments" embraces metal wires as well as plastics filaments.

Abstract: A tabbing machine is employed to place a tab between the release layer and the adhesive layer of an adhesive strip. The adhesive layer of the adhesive strip is double backed and adapted to be placed upon a surgical towel or the like. The tab allows the user of the towel to readily grasp the release layer and remove the same without inadvertently tearing the underlying adhesive layer which is attached to the towel. Two layer adhesive tape is initially fed to a roll wherein the double backed adhesive layer is separated from the release layer. The release layer and the adhesive layer are subsequently reunited at a nip point where a tab is inserted. The tab is then sandwiched between the release layer and the adhesive layer. The tape is subsequently applied to a surgical towel and then cut at the location of the tab. In this manner, the but tab forms the trailing tab of one towel and the leading tab of the other.

Abstract: Minerals, for example, zirconium minerals, are subjected to a chemical process of comminution, in particular with the aid of strong acids. These acids dissolve the carbonatic and silicious cements which hold together the crystalline forms of different mineral species from one another, e.g., magnetic and non-magnetic species to render them amenable to further separation in a subsequent ore dressing stage, e.g., by high intensity magnetic separation. This process is operative as these cements dissolve in acid more readily than most of the other compounds of the ores. This separation was found to take place more effectively than by the usual methods of mechanical grinding and without the disadvantage of an unfavorable particle size distribution which results from grinding. It was found that the same process conditions also resulted in a particularly favorable removal of naturally occurring radioactive contaminants from the minerals, in particuar thorium and uranium.

Abstract: A cup-shaped wheel having an abrasive rim is employed to grind the teeth of a circular saw to an improved contour. Only point or edge contact takes place between the abrasive rim and the tooth. This technique is preferably utilized in conjunction with triple-chip type circular saws of the sort used to cut metals such as steel. The contour imparted to the cutting surface of the tooth comprises a section of an elliptical cylinder and exhibits improved steel cutting characteristics when compared to prior art multi-faceted saw teeth. Since only edge contact takes place between the abrasive rim and the tooth, the wheel is essentially self-dressing.

The free ends of the outer belt means may be buckled in the conventional manner. The rigidity of the inner belt means provides support to the outer belt means.

Abstract: A lifting cushion apparatus is equipped with a plurality of inflatable chambers at least one of which is adapted to have a wedge-like shape when inflated. The wedge chambers may be preformed through the use of wedge-shaped sidewalls and interior separators. Alternatively, the wedge chambers may be formed through the use of an external shaping means such as a string or band placed through a pair of separator bars in a zig-zag fashion. By employing at least four wedge chambers in the cushion apparatus it is possible to achieve at least seven discrete head tilt angles. The head plate of each of the cushion apparatuses is equipped with a coupling means so that two lifting cushion apparatus can be connected together in the tandem fashion. By the judicious placement of the lifting cushions it is possible to lift loads which have a low specific surface strength relative to their weights. Such loads would include, for example, airplanes, busses, tank cars, trucks, subway cars and the like.

Abstract: A warp knitting machine includes a linkage system for translating the rotational motion of a drive crank into a back and forth movement suitable for a weft inserting mechanism. The linkage system includes five separate linkage elements. A first linkage element drives a second linkage element which in turn causes a third linkage element to rotate around a fixed reference point. A fourth linkage element is connected to the junction of the second and third linkage elements at one end and at the other end is connected to a fifth linkage element. The fifth linkage element is pivoted in the center thereof. The rotational motion of the first linkage element causes the fifth linkage element to move in a backward and forward direction. The linkage elements are arranged relative to one another according to a special relationship which helps to smooth out the accelerative forces and to prevent dead points where the linkage elements may lock.
