Patent GB-1085005-A (GB)
Title: Improvements relating to methods of depositing metals on molybdenum
IPC: C25D5/38
Filed: 1966-04-13
Abstract: A metal layer e.g. of Ni or Cu is electro-deposited on a Mo component by cathodically reducing the oxide layer initially covering the component in an electrolyte at a pH at which the reduction potential of Mo is reached until the oxide has been completely removed, and then electro-depositing the metal, the Mo component being enclosed in a reducing medium, preferably the electrolyte, when clean of oxide layer until coated with the metal.  Preferably the whole operation is carried out in one bath, wherein after the oxide layer has been completely removed by cathodic reduction, e.g. in a concentrated HCl solution using a Pt anode, a concentrated solution of a salt of the metal to be electro-deposited e.g. of CuCl2 is added; alternatively, the anode may consist of the metal to be electro-deposited and the pH chosen so that the gradually dissolving metal only begins to be deposited after the oxide layer has been removed.  Prior to electrolysis, the Mo component may be heated in H2 and pickled in an aqueous solution containing HNO3, H2SO4 and NaCl.  The cathodically treated Mo component may be transferred to a separate plating bath, but without rinsing.  The coated molybdenum is suitable for working, e.g. drawing of wire or rolling of foils, wherein it can be annealed between reduction stages without forming oxides or nitrides.

Title: Improvements in or relating to transmission means for supporting and rotating false twist spindles
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/06
Filed: 1964-01-17
Abstract: 1,112,961. False-twist apparatus. KLINGER MANUFACTURING CO. Ltd. 20 April, 1965 [17 Jan., 1964], No. 16578/65. Heading D1D. Means for supporting and rotating a spindle for false-twisting yarn, comprises a track for rotating the spindle about its axis, the track being adapted to contact the spindle tangentially and to move in a direction generally transverse to the axis of the spindle, and magnetic means including two spaced poles disposed on transversely opposite sides of the track for drawing the spindle into engagement with the track. A shaft 7 is mounted in a bearing 4 in a fixed bracket 1. At the upper end of the shaft is a cylindrical member 9 having external bands 10, 11 spaced apart to provide a groove 12 between them; at the lower end of the shaft is a driving sleeve 8. Two horseshoe magnets 13, 14 are spaced apart and are connected by a block 15; like poles of the two magnets are adjacent, and are joined by pole pieces 17, 18 located at transversely opposite sides of the bands 10, 11. Each pole piece is tapered away from the magnet and towards a flattened tip; the field is concentrated across the tips and acts to draw the spindle against the track consistituted by the bands 10, 11, small air gaps existing between the tips and the spindle. Axial movement of the spindle to a position where it is beyond the influence of the field is prevented by the engagement of a ridge 19 with the faces of the groove 12. The position of the magnets may be adjusted to provide a field inclined (e.g. at an angle between 87 degrees and 89¢ degrees) to the direction of movement of the track. To this end, the block 15 which holds the magnets is connected to the bracket by a set-screw in such a way as to allow the magnets to be tilted by set-screws 21, 22. When the magnets are so tilted the resultant field is inclined, e.g. at an angle between 87 degrees and 89¢ degrees, to the direction of movement of the track. With the spindle correspondingly inclined, the rotational force imparted to the spindle by the track exerts on the spindle a component which affects the pull of the yarn on the spindle and prevents the ridge running in engagement with the face of the gap.

Title: Improvements in or relating to electric oscillation generators employing magnetrons
IPC: H01P7/02
Filed: 1942-11-23
Abstract: 601,208. Valve generating circuits. FORMAN, J. Nov. 23, 1942, No. 16593. [Class 40 (vi)] An oscillating or resonant circuit comprises two lines in which the electric oscillations appear and which are bridged by an electrolytic cell having at least 'three electrodes connected to the lines and to the electrical centre of the circuit, such as the positive high-tension supply. The valve may be a four-segment magnetron with adjacent pairs of segments connected together by a metal bridge. Alternatively, the segments may be connected by a similar electrolytic cell, Fig. 5, or each of the segments may be connected to an electrode in the electrolytic cell, Fig. 6. The electrolyte is preferably a slightly acid buffer solution and may be a N/10 aqueous solution of potassium dihydrogen phosphate or a sodium chloride solution, copper electrodes being used. The system may be used with triode or tetrode valves of ordinary construction. Fig. 7 shows a push-pull circuit with lines 43, 44 tuning the grid and anode circuits respectively. In this way shorter waves may be generated and the current distribution is such that a current anti-node is produced at the glass seals and large variations in load do not produce instability or stop oscillation. In addition, automatic impedance adjustment of the Lecher system to the valve and to the load and to the load position is stated to be obtained.

Abstract: 552,482. Wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 24, 1941, No. 16651. Convention date, Dec. 27, 1940. [Class 40 (v)] The signal-to-noise ratio in a radio telegraphic or other signalling system is improved by intermittent propagation of the signal, oscillatory energy being alternately stored and radiated. The receiver may be controlled synchronously with the transmitter so as to be receptive only during the intermittent arrival periods of the pulses. As shown, the oscillatory source 1 is coupled by half-wave or quarter-wave concentric lines 3 to tapping points on a half-wave resonant line 4. The energy stored in the resonator is fed to the aerial 7 when conductive elements on a rotating insulator disk 6 pass between condenser plates 5. At minimum capacity of the condensers 5 a parallel-resonant rejector circuit is formed with the shunt coils 8, whilst at maximum capacity a series-resonant circuit is formed with the series coils 11. Neutralizing cross-connected condensers may alternatively be used to balance out the minimum or residual capacity. The oscillating circuits are enclosed in screens 16. The disc 6 may be driven by a synchronous motor fed through a frequency divider from a crystal oscillator. A similar motor may be used at the receiver to change the circuit from a receptive to a non-receptive condition, and manual or automatic correction of the timing may be provided. The receiver may be arranged to be responsive only to signals above a prescribed threshold value higher than the normal noise level.
