Title: Improvements in electro-magnetic friction devices
IPC: F16D27/00
Filed: 1943-06-22
Abstract: 575,481. Friction clutches. THORNTON, A. A. (Warner Electric Brake Manufacturing Co.). June 22, 1943, No. 10097. [Class 80 (ii)] [Also in Group XXXIV] To prevent distortion due to uneven heating of the annular armature of an electromagnetic friction brake or clutch it is formed of a number of segments of magnetic material, each attached to a sheet metal ring at a part which is spaced from the edges both of the segment and of the ring, the ring having annular deformations to provide rigidity and to prevent warping with temperature variations. Brake mechanism is described in which the armature is carried by a brake drum and rotates the magnet body to a limited extent by friction, when energized, the magnet body effecting the application of a brake shoe to the drum. As shown, the armature 20 is carried by a brake drum 24 and comprises segments 33 of magnetic material spot-welded at points 40 to projections 39 formed on a sheet-metal ring 34 formed also with circumferential corrugations 36, 37 and flanges 35. Slots 46 in the edges of the segments prevent vibration thereof at audiofrequencies. Spring strips 22 secured to the ring and to a ring 23 secured to the drum effect rotation of the armature and serve also to hold it normally in light contact with the magnet body which is rotatably mounted on a flange 30 projecting from the fixed plate 14. The magnet body comprises a U-section core 21 enclosing a winding, and a non-magnetic wear plate 28. The ends of a brake shoe engage a fixed stop and also a pin 17 on a lever 16 pivoted at 15 and provided with a projection 32 disposed between lugs 31 on the magnet core 21. Release springs normally hold both ends of the brake shoe against the stop. When the magnet is energized and the drum is rotating, the magnet body is dragged around to a limited extent by the friction between it and the armature, whereby the lever 16 is operated by one or other of the lugs 31 according to the direction of rotation of the drum, effecting expansion of the brake shoe, one end of which remains in contact with the stop. Counterclockwise rotation of the armature with the drum is effected by the engagement of projections 25, 26 secured to the rings 34, 23 respectively.

Title: Method and apparatus for Acoustic Analysis
IPC: G01N29/24
Filed: 1967-03-06
Abstract: 1,184,333. Acoustic testing of materials. ROCKWELL CORP. 6 March, 1967 [7 March, 1966], No. 10524/67. Heading H4D. An arrangement for detecting variations in the specific acoustical impedance of a workpiece caused by structural discontinuities therein utilizes the variations which such discontinuities produce in an acoustical standing wave pattern created in the workpiece. The invention is described in connection with the testing of panels of sandwich construction utilizing electroacoustic probes comprising either piezo-electric or magnetostrictive elements and adapted to operate in an immersed liquid coupling 24 (Fig. 1) with the panel 6 or in contact therewith via a thin liquid coupling (Fig. 2). In operation, the probe is excited by an oscillator operating in the range 2À5 to 80 Kh to set up a standing wave which acoustically energizes the workpiece throughout its entire thickness so that the latter loads the probe the extent of the loading being a measure of the distance of the discontinuity from the probe (i.e. distance is inversely proportional to, loading) whilst the position of the probe indicates the location of the discontinuity. Fig. 5 shows one arrangement for carrying out the invention involving an additional crystal or magneto-strictive element 134 structurally secured to the main probe element 30 so that both vibrate in unison. The output of element 134 is then fed-back to control the amplitude of the drive produced by oscillator 114 and current changes indicated by the meter 118 are utilized to detect changes in the load on the element 30 resulting from discontinuities in the workpiece. In a modification of this arrangement, the read-out means comprising a meter or a cathode-ray tube is connected to the oscillator via a variable filter, Fig. 8 (not shown). In another arrangement, the probe 3 (Fig. 6) of the kind shown in either Figs. 1 or 2, is connected to a bridge circuit, which is of the resistance-inductance type when the probe comprises a magneto-strictive element and of the .resistance-capacitance type when the probe comprises a piezo-electric element (an example of the latter being described with reference to Fig. 9, not shown) an oscillator 114 driving the probe and an amplifier 116 feeding an indicating meter 118. A further arrangement employs an FM signal generator supplying the probe via a self-balancing bridge connected to a null detector, Fig. 7, not shown. In the operation of all arrangements the apparatus is first calibrated with the probe in contact with an area of the workpiece known to be free from defects to produce an initial reading to which subsequent test readings are related. Typical readings at defect free areas and at areas having defects at different distances from the probe are shown in Figs. 3 and 4 for a honeycomb and a laminated panel construction respectively. It is stated that instead of a meter read-out, other means such as Lissajous patterns on a cathoderay tube or digital read-out means may be employed.
