Abstract: 1,229,395. Treating zirconium. GENERAL ELECTRIC CO. March 5, 1969 [March 20, 1968], No, 11786/69. Headings C7E and C7U. Zirconium or its alloys are freed of surface contamination due to fluorides by immersing the surface thereof in an aqueous solution comprising at least 500 g/l alkali metal hydroxide for a contact time of 1 to 120 minutes, and then removing the surface from said solution, and rinsing the surface with water before it becomes dry. NaOH may be used in concentrations from 750-1500 g/l or KOH, from 1000 g/l to saturation, immersion in each case being for preferably 1-60 minutes at 100 to 180‹ F. In preparing Zr or Zr alloy tubes for use as cladding for nuclear reactor fuel material, the Zr is etched in HNO 3 /HF, resulting fluoride contaminant is removed as above, and then the tube is oxidized in high-pressure steam to give a black coherent oxide film whose quality is enhanced as a result of the fluoride decontamination step.

Abstract: 1290937 Ultrasonic testing G BAUM 20 Nov 1970 55163/70 Heading H4D ' A method of producing an image of ultrasonic signals includes the steps of transmitting ultrasonic pulses to an object, receiving a set of echoes therefrom, converting said set of echoes into a set of collimated light beam signals having an intensity which is a function of the echo intensity, displacing said light beam signals to correlate the positions of echo sources on said object with the positions of said light beam signals in an image zone to produce an image of the physical features of said object. A transducer 1 transmits ultrasonic pulses to an object 2 and detects echoes therefrom and its output intensity modulates a laser 8 inside a light-proof box 9, mounted on a rod 4 which rotates thus scanning the transducer across the width of the target 2. The laser beam is reflected from an oscillating mirror 11 to a photographic film 12. The mirror scans the beam across the film at a rate proportional to the velocity of the ultrasonic beam through the object 2 producing a range-angle image. The transducer is made to scan the object 2 at a number of positions equidistant from a point in the object 2 by rotation of the transducer 1-box 9 assembly about pivot 16. The assembly is also stepped up or down to produce composite pictures at different levels, each picture being formed on a different film frame. The mirror may be replaced by a KDP or KD<SP>*</SP>P opto-electric element which deflects the beam by variation in its refractive index, or by a circular rotating wheel having reflecting facets on its circumference (Figs. 7-9, not shown) or by an internally scanned laser. Various optical arrangements are shown, varying the positions of the light source, deflecting element &c. There is also described a system wherein the light beam passes to the film 12 via a semi-transparent mirror and the reflected beam is viewed simultaneously with recording via photochromic and dichroic reflectors and an optical filter (Fig. 8, not shown). The viewing and recording may also be carried out using a phosphorescent screen (Fig. 9, not shown).
