Patent GB-797712-A (GB)
Title: Process for bonding various metal bodies to light metal as in casting or coating
IPC: C23C2/32
Filed: 1956-05-28
Abstract: To bond a base metal article to a light metal, the light metal in molten condition is brought against the surfaces of the base metal article which is subjected directly to mechanical vibrations, of from 1000 cycles per minute up to the maximum audible frequency, with amplitude 8-10 thousandths of an inch, the vibrations maintained for a period of 5 seconds to 5 minutes during which time the light metal remains molten, the vibrations discontinued and the molten metal caused to freeze against the surfaces of the base article.  Light coating metals mentioned are magnesium, aluminium and their alloys while base metals mentioned are iron, steel and alloys of molybdenum, cobalt or nickel.  The vibrating means may be a compressed air vibrator, motor driven vibrator, or electrical low frequency vibrator.  In an example, Fig. 2, not shown, ferrous valve elements for I.C. engines were coated with aluminium on their head portions by dipping the head portions into a bath of molten coating metal.  The vibrator motors started as the valves entered the bath.  The time was about 7 seconds for operation and bath travel.  As the valves were withdrawn the motors stopped, the valves turned through 90 degrees so that their stems were horizontal, allowed to drain for 10-15 seconds, further turned through 90 degrees so that their heads were uppermost, and further vibration applied until solidification was complete. There may be an interface bonding layer, e.g. of tin.

P., 57, Broughton Avenue, Finchley, both in London. June 10, 1932, No. 16474. [Classes 13 and 118 (ii).] A magnetostrictive pressure wave transmitter and/or receiver suitable for use in echo-sounding, subaqueous signalling systems, and for detecting underwater bodies, such as icebergs, comprises a body of magnetostrictive material which exhibits substantial volume changes when subjected to varying magnetizing forces, said body being immersed in a liquid medium in which wave propagation is to be effected so that pressure waves are propagated directly as a result of such volume changes. Nickel-iron alloys containing from 20 per cent to 50 per cent nickel and 80 per cent to 50 per cent iron which exhibit substantial volume changes are preferably used in carrying out the invention. Fig. 1 shows a construction in which a magnetostrictive body M adapted to be energized at its natural frequency of vibration is suspended by resilient spacing members S in a jacket J of insulating material. The bottom of this jacket is open to the sea or other liquid medium and is provided with a flange F for attachment to the ship's bottom. The disposition of the magnetic circuit and of the energizing and polarizing windings is similar to that described in Specification 402,123 and comprises E-shaped yokes Y on either side of the body M and coils L as shown. The body may have a single winding associated therewith for both transmission and reception or two separate windings may be employed one for transmission and the other for reception. Fig. 2 shows a modification in which the jacket J is dispensed with and the body is mounted horizontally within a reflector R shaped so that all waves, whether reflected or direct, are in phase.

Abstract: 1511711 Ink ribbon mechanism ING C OLIVETTI & CO SpA 22 April 1975 [24 April 1974] 16546/75 Heading B6F Ink ribbon feed mechanism for receiving cartridges of either multi-pass ink ribbons or single pass carbon coated ribbons includes feed and control means engaging the ribbon in use, and ribbon guides 14, and a single control member 53 having normal and operated positions, the control member, when shifted to its operated position when a cartridge is mounted on the mechanism, acting both to lift the guides 14 and to disengage the ribbon engaging means to facilitate the removal of the cartridge. Two sets of ribbon engaging means are provided. For multi-pass ink ribbons, reversal control sensing means 108, 109 contact the peripheries of the ribbon wound on the two spools. When a single pass ribbon cartridge is mounted on the mechanism, these sensing means are held out of contact with the ribbon peripheries by an appropriately shaped aperture (158, Fig. 3, not shown) in the cartridge. For single-pass ribbons, feed rollers 43, 71 contact the ribbon. When a multi-pass ribbon cartridge is mounted on the mechanism, the path of the ribbon avoids the rollers 43, 71 (Fig. 2, not shown). Feeding multi-pass ink ribbons; ribbon reversal On each print operation, a shaft 36 is driven, whereby a ribbon guide lift cam 27 lifts the guides 14 by successively varying amounts, and a shaft 47 is driven. Slidably keyed on the shaft 47 is a sleeve 83 which carries alternative pin wheels 82, 87 each engageable with a respective spool pin wheel 84, 88. The sensing fingers 108, 109 contact the peripheries of respective spools, and when a spool is about to be exhausted, push a pin 102 beyond the centre point of a bi-stable spring 101 whereby the sleeve 83 is shifted along the shaft 47 by engagement of an appropriate pin 96 or 97 in a respective helical gear 89 or 90. Feeding single-pass carbon coated ribbons A cartridge containing a carbon ribbon is formed with an aperture (158, Fig. 3) which holds the sensing fingers 108, 109 out of the engagement with the spool peripheries but in such a position as to ensure engagement of pin wheels 82, 84 for taking up the ribbon. The ribbon is driven by feed rollers 43, 71 driven from the shaft 36. Mounting and removing the ribbon cartridge The ribbon mechanism assembly is covered by a pivotable cover (172, Figs. 4, 5, not shown) which is first pivoted back to expose the cartridge. A manual lever (139, Figs. 2, 3, not shown) is then operated to displace the control member 53 to its operated position, raising guides 14 and disengaging the ribbon engaging members 108, 109 and 71. The old cartridge can then be removed and a substitute mounted. The lever (139) should then be returned to its normal position, but in case of mistake, the return of the cover (172) ensures return of the lever (139). In a modification, the return to normal of the member 53 can be effected by the first printing operation, through a cam (191, Fig. 7, not shown) on the shaft 36.

Title: An improvement in agricultural tractors
Inventor: NORCLIFFE KENNETH ADRIAN
IPC: A01B67/00
Filed: 1966-04-16
Abstract: 1,118,658. Tractor power lift mechanisms. DAVID BROWN GEAR INDUSTRIES Ltd. 11 April, 1967 [16 April, 1966], No. 16777/66. Heading A1P. In a tractor having a hydrostatic transmission and a power lift linkage the draft of an attached implement is controlled by signals derived from the charging pressures in the transmission and a pivoted weight 22 is associated with the control linkage in order to offset variations in the transmission pump pressure due to changes in the fore and after pitch of the tractor. A manual lever 26 operates on valve 49 to set desired draft of the implement. A change in soil resistance causes a change in the hydraulic pressure of fluid supplied by pump 10 to motor 14 to cause a piston 17 to move and operate valve 49 via linkage 19, 20, 24 and lever 25. A change in the fore and aft pitch of the tractor also causes a change in the pressure of fluid delivered by the pump 10 and thus movement of links 19 and 20. However, movement of the link 20 is balanced by pivoting of the weight 22 so that the valve 49 is not operated. The arrangements of the two alternative hydraulic circuits for operating the lift mechanism are similar to those described in Specifications 1,002,492 and 983,099. The pivoted weight 22 can be replaced by a gyroscopic device or by mercury operated electrical switches. The control valve 49 can be of rotary type and the piston and cylinder 16, 17 can be replaced by a diaphragm device.
