Title: Super conductor cavity resonators
IPC: C25D11/26
Filed: 1972-02-08
Abstract: 1335165 Cleaning and anodically oxidising niobium SIEMENS A G 8 Feb 1972 [12 Feb 1971] 5896/72 Headings C7B and C7E [Also in Division H1] The surface of a super conducting niobium cavity resonator is chemically polished and then electrolytically anodized. The polishing is done in a bath consisting of 60% by volume cone. nitric acid and 40% by volume of 40% hydrofluoric acid at 40C. This removes a layer of 50Á in 5 minutes. In the anodizing process, the resonator itself is used as a bath for a 25 per cent by weight solution of ammonia. A niobium tube is used as cathode and a pre-oxidizing process carried out using a current density of 3mA/cm<SP>2</SP> at 25C until a voltage of 20V is obtained across the electrodes. The thin oxide layer thus formed is removed by washing with 40% hydrofluoric acid and the resonator again filled with ammonia solution. The main oxidization process is carried out using a current density of 3mA/cm<SP>2</SP> until 100V is reached (about 10 minutes). It is stated that a constant voltage source may be used instead of a constant current source, e.g. the voltage may be raised in steps of 20V from 20 to 100V, a voltage rise being imposed whenever the current drops to 25 per cent of its initial value. Electrolytic polishing may be used instead of chemical polishing.

Title: Device for determining the dynamic unbalance of wheels
IPC: G01M1/28
Filed: 1950-03-10
Abstract: 686,912. Testing balance of rotary bodies. HUNTER, L. March 10, 1950 [Aug. 11, 1949], No. 6054/50. Class 106 (ii). A device for determining the dynamic unbalance of a rotating wheel comprises a pair of weighted arms arranged to be mounted on the wheel and to rotate with the wheel, and means for moving the weights relatively to the wheel and towards or away from each other about the axis of the wheel during its rotation, the said means being manually adjusted whilst the wheel is rotated until all noticeable vibrations have been caused to vanish. As shown in Figs. 7 and 8, the device comprises a disc 16 carrying a centrally arranged gear-box 7 from which four axially arranged control knobs 63a, 49a, 39a and 25a project. On the inner face of the disc 16 are two weights 76 and 76a mounted on arms 74 and 75 respectively which are pivoted to axially arranged shafts extending from the gear-box. The device is secured to the wheel of a car by adjustable arms 84 on the device which can be forced into engagement with the rim of the wheel. The wheel, with the device attached to it, is then rotated at speed and by stopping or slowing down the rotation of knob 25a, relative movement between the disc 16 and the two weights 76 and 76a is made in one direction. Alternatively, by stopping or slowing down the rotation of knob 39a relative motion between the disc 16 and the weights is produced in the other direction. Stopping or slowing down the rotation of one of the knobs 49a and 63a causes the two weights 76 and 76a to be moved equal distances towards one another about their pivots and a similar manipulation of the other knob causes the two weights to move away from each other about their pivots. The knobs can thus be adjusted while the wheel is rotating until all noticeable vibrations due to any unbalanced masses have been eliminated. A pointer 79 within the gear-box 7 is arranged to indicate through a window on a scale 82 the magnitude of the correcting weight required, this being dependent upon the final setting of the knobs 49a and 63a. The gear-box also has a counterweight locating mark 83 indicating the path of a line which bisects the angle between the weight carrying arms 74 and 75 so that the correcting weight can be correctly attached to the wheel. The device is such that when the arms 74 and 75 are moved jointly in one direction relatively to the disc 16 the gear-box 7 is also rotated relatively to the disc 16 by the same amount and in the same direction, the mark 83 being a fixed indication on the gear-box 7.
