Abstract: 806,216. Measuring sounds and like vibrations. BENDIX AVIATION CORPORATION. Oct. 4, 1956 [Oct. 19, 1955], No. 30313/56. Class 118 (2). Wave energy distribution in a liquid subjected to ultrasonic wave action is determined by placing a thin sheet of material, capable of being permanently deformed by the implosion of cavitation bubbles, in contact with the liquid in the position desired to be investigated, A sheet of foil, for example of lead, tin, aluminium or copper, is held by its edges and immersed in the desired position in the liquid, whereupon pitting occurs in proportion and distribution indicative of the intensity and distribution of the ultrasonic energy. Suitable thickness of various metal foils are suggested, but other materials having similar properties of deformability may be used. A device for holding foils for insertion into a cylindrical container of the kind employed in commercial types of ultrasonic cleaning apparatus comprises a frame of metal wire or rods of appropriate stiffness and resistance to corrosion. Two rings 11 and 13 are spaced as shown by four rods 14, 15, 16 and 17 fixed thereto, as by soldering. A handle 12 is provided. The foil sheets include a bottom horizontal disc 19 having its edges turned over the ring 13, a vertical peripheral sheet 22 also attached by bending its edges, and further interior vertical sheets 26 and 28 secured by their vertical-edges. Any or all of these sheets may be in position for testing. The horizontal distribution of cavitation in the container may be tested at different levels to find the optimum location of articles for cleaning by supporting the ring 13 and foil 19 at any desired elevation. After test a disc 19, for example, may be pitted to appear as shown in Fig. 4. Specification 797,417, [Group XXXIX], is referred to.

Apparatus for removing scale or rust from elongated metal such as metal wire or strip comprises, as shown in Fig. 1, a roller breaker 3 in the form of a housing divided longitudinally into two halves, each of which has a group of rollers which co-operate to break the surface layer of scale or rust by forming a winding passage for the metal and are arranged so that when the halves are separated the metal wire or the like may be inserted or removed, and a cleansing device 4 to remove particles of scale or rust remaining on the metal. The device 4 comprises a tube 7, rotatable about an axis 6 to a horizontal position for insertion of the wire in the slot 32, filled with powdery or coarse grained material such as iron pyrites, and the metal wire may be moved transversely relative to the material by replacing the roller 5 by an eccentric or elliptic roller. Discs 37 and 38 further clean the wire, and a magnetic device 36 removes any magnetic particles still adhering. Fig. 4 shows the roller-breaker in cross section. Half cylinders 10 and 11 hinged at 12 form the housing, and pairs of rollers 14 and 15 are disposed each with their axes in the same cross sectional plane. Rollers 16 and 17 disposed at angles to these are staggered along the length of the housing and form the winding passage for the wire. Weights 20 may be added to the top of the housing if desired. The rollers may be driven or freely-running. A roller breaker for the treatment of strip is shown in crosssection in Fig. 6. Here the rollers are all arranged horizontally but each pair 21 and 22 of the rollers have their axes slightly offset longitudinally to form a sinuous passage for the strip 23. The rollers may overlap the edges of the strip as shown.
