Title: Improvements relating to the electrolytic treatment of metal wire and the like
IPC: C25F7/00
Filed: 1953-05-27
Abstract: 726,133. Electrolytic treatment of wire. METRO-CUTANIT, Ltd. May 27, 1953 [Oct. 9, 1952], No. 14796/53. Class 41. In a method of electropolishing or otherwise removing metal from the surface of metal wire, strip or ribbon, by its treatment as an anode in an electrolytic bath, the surface of the electrolyte is covered by a layer of an insulating liquid of lower specific gravity than the electrolyte, in which layer the current connection to the wire is made. A layer 3 of insulating liquid, which may be a saturated hydrocarbon such as a saturated petroleum fraction, is arranged on top of electrolyte 2 in a vessel 1 having a cathode 7. Wire 4 is led through the electrolyte by insulated guide rolls 5 and metal roll 6, which roll 6 dips into the insulating liquid layer 3 but not into the electrolyte and supplies current to the wire. The method may be used when the electrolyte contains a component exhibiting partial solubility with respect to petroleum, such as ethanol in an aqueous solution of phosphoric and citric acids for electropolishing chromium-nickel-steel, or methanol in an electrolyte for electropolishing molybdenum wires. When the electrolyte is used at an elevated temperature, the insulating liquid may be a saturated hydrocarbon which is liquid at the working temperature but solid at room temperature.

Title: Method and apparatus for adjusting braking force
IPC: B60T8/60
Filed: 1975-04-10
Abstract: 1502806 Antiskid braking systems MESSIER-HISPANO 10 April 1975 [12 April 1974] 14819/75 Heading F2F Braking is interrupted when the deceleration of a braked wheel exceeds a threshold value, and is allowed to resume after a delay which is a function both of the extent of the initial deceleration and subsequent acceleration of the wheel beyond a predetermined threshold. As shown, the signal from a tachogenerator 3 is filtered at 4, differentiated at 5, and amplified as a function of frequency in a variable gain amplifier 6. The resultant deceleration signal is passed by a diode 7 to a comparator 8 and if greater than a threshold value is amplified at 12 and applied to the solenoid 13 of a valve which prevents the transmission of pressure to the brake. The deceleration signal also charges a capacitor 92, to an extent dependent on the magnitude and duration of the signal, so that solenoid 13 remains energized as the signal decreases. When the wheel begins to accelerate, the sign of the signal at the output of amplifier 6 is reversed and the signal is passed by diode 10 to a device 11 which discharges the capacitor at constant current when the acceleration signal is greater than a threshold value, so shortening the period before the capacitor voltage drops below the value required to energize coil 13. The control system as applied to aircraft also includes known circuits 22, 23 which respectively prevent braking unless the undercarriage shockabsorber is compressed (unless wheel rotation occurs) and prevent braking if wheel speed falls below a threshold value (unless the vehicle speed, derived from that of the fastest wheel, is lower than a predetermined value).
