Title: Method of coating aluminium and aluminium alloys with metals which are below aluminium in the electromotive series
IPC: C23C8/40
Filed: 1956-04-03
Abstract: Aluminium and its alloys are coated with at least one metal (M) which is more electronegative than Al by immersion in a molten bath made by fusing together AlCl3, at least one of the group NaCl, KCl, LiCl, and chlorides of one or more of the metal(s) M; whereby the Al oxide film is removed and a coating of the metal(s) M is deposited on the Al. Preferably the alkali metal chloride-AlCl3 component of the bath contains between 52 and 82 mol per cent, the chloride(s) of the metal(s) M being a minor proportion of the bath, 1 to 25 per cent by weight being suitable.  Preferred metals M are Zn, Sn, Pb, Cd: but the chlorides AgCl, AuCl, AuCl3, CoCl2, CrCl3, CuCl, CuCl2, FeCl2, GaCl3, HgCl, InCl3, MnCl2, NiCl2, PdCl2, RhCl3, TlCl, may also be used.  A further metal coating may be applied by immediately immersing the thus coated Al in a pool of at least one of the molten metals M.  In such case the above specified fused bath may be floated on the molten pool and preferably contains chloride(s) of M. Examples describe coating with (1) Zn, (ii) Sn using the fused bath only; and with (iii) Sn, (iv) Cd-Zn alloy using both the fused bath and metal pool.  Specification 784,802 is referred to.

Abstract: 1,269,017. Particle accelerators. THOMSON C.S.F. 3 March, 1970 [12 March, 1969], No. 10215/70. Heading H1D. The electron beam emerging from a particle accelerator passes through a first deflecting means Dl, Fig. 1, which deflects the beam through an angle of, for example, 37 degrees, and through a second deflecting means D2 adapted to produce a deflection in the same plane of, for example, 127 degrees so that the final path intersects the original path preferably at a right angle. The first deflection means Dl is achromatic and comprises three electromagnets with sector shaped polepieces arranged as shown. The edge of each polepiece may be defined by a rotatable semicircular member (Fig. 3, not shown) so that the angle it makes with the beam may be varied. The second deflection means may comprise a single electromagnet E4 with sector shaped polepieces, the end faces of which are inclined at 35 degrees to the normal to the beam path (Fig. 4, not shown). The opposed faces of the polepieces are preferably inclined to each other so that the index n = 0À5 where  where B is the flux and R the radius of the particle trajectory; this gives identical convergence properties in two planes. The deflection means D2 may be followed by three quadruple lenses which are successively convergent, divergent and convergent so that the output beam may be focused to a circular cross-section (Fig. 5, not shown). Alternatively the polepieces of the magnet E4 may comprise a first section with n = 0À5 and a second section with a negative field gradient where n = 2 or 3 (Fig. 6, not shown); the entry face is normal to the beam whereas the exit face is inclined at a variable angle. The beam may pass through scanning means in the form of four coils and associated polepieces which taper conically along the beam path (Fig. 7, not shown), Alternatively a scanning coil may be associated with magnet E4 for scanning in one direction, and an additional electromagnet may be provided adjacent deflection means D1 for scanning in the other direction (Fig. 8, not shown). The system is rotatable about the axis X-X<SP>1</SP>.

Title: Improvement in controlling devices for ship's steering gears
IPC: B63H25/28
Filed: 1927-04-25
Abstract: 272,180. Waterbury Tool Co., (Assignees of Crain, J. J.). June 3, 1926, [Convention date]. Steering gear. - In ships' steering gears embodying a variable capacity pump a differential gear actuated by the follow-up gear and the primary control govern the control shaft of the pump adjusting gear. The connection between the steering wheel and the gear may include a pair of synchronous electric motors. Means also are provided for over-riding the pump control when the rudder approaches its extreme angular positions. A hydraulic pump 16 driven by the motor 18, is connected by pipes 15, 17 to the ram cylinders 11, 11<a>, the rams 12 thereof having a spherical joint connection 14 with the tiller 10. Gearing on the tiller head operates the follow-up shaft 26 which carries a planet pinion 24 forming part of a differential that actuates through gearing 21, 20 the control shaft 19 which alters the inclination of the swash plate of the pump. The other unit 38 of the differential is actuated by a hydraulic pump and motor 36 which is driven off the main motor 18 by a chain 34. The hand wheel 53 is coupled by synchronous motors 50, 48 to the control shaft 44 of the hydraulic gear 36. Movement of the hand-wheel sets the shaft 44 so that the shaft 37 is rotated and in turn the shaft 19 is moved whereby the main pump operates to move the rudder. The follow-up gear then follows up to set the control 19 in neutral when the handwheel is stopped. To prevent rudder over-throw, a cross pipe 60 between the pipes 17, 15, has a valve 62 which controls the pipe line 63 to a pressure-control unit 65. The piston 66 of this device has a plate 67 having restraining springs 71 and adapted to contact with one of the arms 73a, 73<b> of a pivoted lever which is coupled by an arm 73 with the, control shaft 44. In the control gear, the gear wheel 45 is mounted so that the shaft 44 has a longitudinal movement which results in the arms 73<a>, 73b being moved under the ordinary control, and these arms when returned to neutral by the pressure, control unit thus act on the main control to set the, main pump in neutral. In a modification, a hydraulic motor driving the rudder stock by gearing is substituted for the hydraulic rams. Specifications 13895/07 and 13897/07, [both in Class 102, Pumps &c.], are referred to.

Abstract: 997,934. Welding by fusion. SHIN-MITSUBISHI JUKOGYO KUBUSHIKI KAISHA. March 23, 1962 [Dec. 30, 1961], No. 11178/62. Heading B3R. In tandem arc-welding the trailing bead is deposited on the leading bead when the latter has solidified and cooled to a temperature such that martensite is in the process of being precipitated. The welding parameters used in depositing the leading bead are selected to produce a cooling rate of the bead such as to produce a structure consisting of ferrite, a transitional structure and martensite with or without pearlite. The plates being welded may be of Mn-Si steel or of a steel containing 0À99% Mn, 0À26% Si, 1.57% Ni and 0À3% Mo. The weld may contain one or more of 1-1À5% Mn, 0À3-0À5% Si, 0À5-4% Ni, 0À1-0À5% Cr and 0À1-0À5% Mo. A preliminary bead 7 containing alloying ingredients may be deposited by a submerged arc-welding head 6, the alloying ingredients being in the electrode 8 and/or the flux 4. The flux is picked up by a device 9 and the bead 7 is completely remelted by a carbon dioxide shielded metal arc-welding head 10 to deposit the leading bead 11. After cooling at a rate and to a temperature as described above, the leading bead 11 is covered by a trailing bead 12 produced by a consumable electrode of a submerged arc-welding head 16. The upper portion of the leading bead 11 is remelted but the lower and major part -is reheated to a temperature such that subsequent cooling produces a tempering effect. The trailing bead 12 is cooled at a similar rate to the leading bead. The submerged arc-welding head 6 may be dispensed with.
