Title: Improvements in and relating to the electrolytic treatment of metallic surfaces
IPC: C25D7/10
Filed: 1948-03-17
Abstract: 661,273. Electrolytic treatment of bearing surfaces. MONOCHROME, Ltd., and WILSDON, S. C. March 17, 1949 [March 17, 1948], No. 7933/48. Class 41. An electrolytic process for the production of metallic bearing- surfaces having lubricantretaining recesses or grooves therein comprises constituting the bearing surfaces as one electrode and forming the recesses or grooves therein by, and in a pattern corresponding to, the form of the relief surface of the other or pattern - controlling electrode. In the arrangement shown in Fig. 4, electrolyte 3 is confined between a cylindrical bearing surface 1 functioning as a cathode and an anode 2 formed with projections 4. Projections 5 corresponding to the projections 4 are formed on the surface 1 by the electrolysis. In an alternative arrangement the surface 1 is the anode and the surface 2 is the cathode, in which case recesses are formed opposite the projections by electrolytic etching. In the arrangement shown in Fig. 6, the surface 1 after having been used as cathode (with the surface 2 as anode) and plated with projections 5 is displaced as shown and then used as anode, whereby the recesses beween the projectors 5 are etched electrolytically. In a further arrangement the bearing surface after the projections 5 have been formed has the whole surface etched electrolytically or chemically. Alternatively it may be etched in the recesses only by masking the non-recessed part of the bearing surface. The pattern-controlling electrode may be coated between the projections and along the sides of the projections with a dielectric material to ensure that substantially only the part of the bearing surface opposite the projections is subjected to plating or etching. In the case of a bearing surface of aluminium, the surface may be etched whether the patternforming electrode is an anode or cathode, suitable electrolytes being sodium chloride or nitrate. Mixtures of chlorides, nitrates and sulphates can also be used. Specifications 561,788 and 661,274 are referred to.

Title: Improvements in or relating to thermionic valve circuits for detecting an amplitude-modulated pulse train
IPC: G01S7/292
Filed: 1945-04-05
Abstract: 601,124. Pulse demodulating circuits. WHITFIELD, H. R., and DANIELS, J. M. April 5, 1945, No. 8482. [Class 40 (v)] Apparatus for demodulating a pulse train modulated in amplitude comprises a reactive circuit arranged to charge or discharge through an electronic switch during each pulse period, at a time constant of the order of the recurrence period or less, to a level proportional to the amplitude of the pulse, and to be isolated during the interval between pulses when the charge remains substantially constant. A stepped wave form is therefore produced approximating to the modulation envelope. In Fig. 1, valves V1, V2 act as an electronic switch for connecting capacitor C6 to the charging source for each pulse duration only. The valves are normally held below cut-off by bias voltages applied to terminal 2 and via resistors R7, R8 respectively. A synchronising pulse is applied at terminal 3 coincident with each input pulse at terminal 4, and initiates a block oscillation, applying a positive pulse through capacitor C8 to render valve V2 also conducting for the duration of the pulse. Capacitor C6 charges or discharges to a level depending on the equivalent resistance of valve V1 which is determined by the amplitude of the input pulse applied to its suppressor grid via terminal 4. After the blocked oscillation, valve V1 is cut-off and negative pulse through. capacitor C8 cuts off valve V2 to isolate capacitor C6 until the next pulse occurs. A filter net-work C9, R9 removes the D.C. component from the modulation voltage across capacitor C6. In Fig. 3 blocking oscillator V3 is biassed via R12 and a synchronising pulse at terminal 6 initiates a blocked oscillation coincident with each input pulse at terminal 8. A positive bias at terminal 7 ensures that rectifiers W1, W2 and diodes V4, V5 are non-conducting between pulses so that capacitor C15 is isolated and maintains the charge impressed by the last pulse. When valve V3 oscillates, the rectifiers conduct to allow the pulse from terminal 8 to charge or discharge capacitor C15 through diodes V4 or V5 respectively in sympathy with the change in pulse amplitude. Capacitor C15 is connected to terminal 8 through de-coupling net-work C16, R19 to minimise leakage. Specification 601,125 is referred to.

Abstract: 849,551. Tobacco smoke filters. CIGARETTE COMPONENTS Ltd. March 12, 1957 [March 19, 1956], No. 8552/56. Class 130. Individually helically twisted strips 10, Figs. 1 and 2, of nylon or polythene, or of viscose or cellulose acetate with or without thin metal coatings or laminated with a foil or foils, are wrapped, with a longitudinal or helical stuck seam, in a garniture 13 by a preferably transparent paper, cellulose acetate or viscose band 14 to form a filter rod subsequently subdivided as for use in tobacco pipes. An alternative wrapper comprises tubes 15, 16, Fig. 4, butt-jointed at 15A, 16A, and a lap-jointed tube 17. By mounting supply reels 11, 12 of the strips 10 on a rotating head, the strips may be made to lie in helices about the rod axis, e.g. so that each strip touches the wrapper at at least one point. Untwisted strips 10 are first formed individually or by slitting a sheet, or may be pressed from round filaments by rollers, the rollers, or the filaments before entering them, being heated if necessary. Each strip 10 is then twisted in a spinner, the spinner and/or the strip before and/ or after passage therethrough being heated to "set" the twist if necessary. The twisted strip 10 is fed to a storage reel or directly to a machine making filter rods. About half of the strips 10 in a filter rod may have a twist of opposite hand to that of the others. The strips 10 may be randomly bonded to each other and adhered to their wrapper, e.g. a solution of 25 % by weight of polyvinyl acetate resin in 75 % by weight of methylated spirit is sprayed on the bunched strips before applying a cellulose acetate wrapper, the spirit being evaporated off after subdivision of the resultant filter rod. A polystyrene solution or emulsion may alternatively be used as a bonding agent. Specification 803,472 is referred to.
