Title: Improvements in or relating to the electrolytic etching of zirconium and zirconium-base alloys
Inventor: DELAFOSSE JACQUES
IPC: C25D5/38
Filed: 1964-09-23
Abstract: Zr or Zr base alloy is electrolytically etched by subjecting the metal to electrolysis as anode in a bath comprising HNO3 and a source of fluoride ions, the electrolytic process comprising a first stage carried out a current density and for a period of time such that there is formed on the metal an oxide film having a thickness of more than 6 microns and a second stage carried out at a voltage which is lower than that of the first stage, during which second stage the oxide film breaks away.  Oxide films which were present on the metal initially break away with the anodically produced oxide.  The temperature of the electrolysis may be from 10 to 25 DEG C. Different concentrations of HNO3 and fluoride ions may be used during the oxidizing and break-away stages.  The two stages may be repeated.

Abstract: 853,381. Toy pistols. CRESCENT TOY CO. Ltd. Dec. 23, 1957 [Dec. 21, 1956], No. 39055/56. Class 132(3). A cap firing toy pistol has a cylinder 16 rotated by a gear 24 engaging projections 25 at the forward end of the cylinder, this end being closed, the gear 24 being driven through a gear 22 by movement of a cap feed finger 13 which is pivoted, with frictional restraint imposed by a dished spring washer 14, Fig. 3, to a circular portion 12 of an arm 6 of a spring loaded trigger 3. The cylinder 16 is supported in a bearing in the pistol body by a forwardly extending sleeve 37 and is prevented from moving rearwardly by a downwardly extending part 44. The gears are mounted on one side of a vertical partitition 30, the other side forming a magazine for a roll of caps. On operating the trigger to feed a cap forward and trip a hammer 8, a lateral extension 20, Fig. 3, on the finger 13 rotates the gears and cylinder and in so doing is itself pivoted counterclockwise. On return of the trigger, the finger 13 is clear of the drive to the cylinder and bears against a guide surface 28 formed on the hammer 8 and is thereby pivoted clockwise against the frictional restraint to its initial position. To insert a fresh roll of caps, the pistol is opened by releasing a latch 38 which engages a pin 40, Fig. 4, and the partition 30 slid rearwardly of the cylinder under the control of a ram rod 36 which is a sliding fit in the sleeve 37. The pistol may be die-cast in two halves which are then pinned together with the assembly constituting the cylinder 16, ram rod 36 and magazine trapped in position between them. According to the Provisional Specification, the gear which rotates the cylinder may be fixedly mounted on one end of a spindle extending parallel with the axis of the pistol and fixedly by carrying at its other end a second gear which engages with the cap feed finger.

Abstract: 1512690 Measuring remanence of magnetic recording media BASF AG 26 Sept 1975 [28 Sept 1974] 39494/75 Heading GIN A device for the non-destructive measurement of the remanent flux density of a magnetic recording disc 1 involves recording a signal on the disc by means of a pair of writing heads 4a, 4b and measuring the resultant voltage read by a pair of reading heads 5a, Sb the frequency of the write currents being matched to the rate at which the disc moves so that the spacing e of the heads from the disc surface is between one fifth and one fortieth of the wavelength of the recorded magnetic variations on the disc, the voltages from the read heads being summed in a summing stage (12) Fig.3 (not shown). For example with a disc speed of three metres per second, i.e. 180 r.p.m. for a disc circumference of about one metre, a frequency of the writing current of fifty Hertz, a distance c between heads of 8À5 mm. and a disc 2mm. thick i.e. spacing e of 3À25 mm, the wavelength recorded was 60 mm i.e. e is about one twentieth of the recorded wavelength. The width d of the head gap is roughly equal to e which leads to a cheap head. The measurement results may be used in a coating control device for the manufacture of magnetic discs or tapes.

Abstract: 867,669. Fluid-pressure servomotor control systems. GENERAL ELECTRIC CO. Dec. 30, 1957 [Jan. 2, 1957], No. 40257/57. Class 135. In a controller for constant-speed drives change of speed signals are transmitted to a control valve with a gain characteristic depending on the rate of change of signal; signals of high rate of change are transmitted with high gain solely by a mechanical linkage and signals of low rate of change are also transmitted with low gain by a mechanical-hydraulic network having a time lag and connected in a subtractive sense with respect to the mechanical linkage, while signals of intermediate rate of change are transmitted with and intermediate gain depending on time lag. In Fig. 1 the mechanical linkage comprises a connecting rod 50 coupled to an input such as a speed sensor 12 and to a link 56 pivotally mounted at 57 and having its other end connected by a link 60 to an intermediate position on link 62, one end of which is connected to an actuating rod 66 of a a control valve 20 and the other end of which is connected to the piston rod 36 of the power deviee 16 of the parallel mechanical-hydraulic lag network, which comprises a link 44 pivotally connected at one end to the rod 50 and at its other end to the piston rod 36 and at an intermediate point a pilot valve 22 controlling the power device 16. In operation, a rapid increase of speed causes the connecting rod 50 to rise, which movement, through the mechanical linkage, causes a large downward movement of the control valve 20 before an appreciable movement of the parallel mechanical-hydraulic network has occurred. A slow increase in speed, however, allows the pilot valve 22 of the mechanical-hydraulic lag net work to control the lowering of the power device 16 which acts to reduce the magnitude of downward movement of the control valve 22 caused by the mechanical linkage. A torquemotor, solenoid or crystal or ceramic actuator 18 may be incorporated in the mechanical linkage at the pivot point 57 for introducing trimming signals. The interaction and magnitude of the movements-is determined by the moment arms of the levers. Instead of speed the input may be pressure or temperature.
