Title: Improvements in or relating to the manufacture of metal articles
Inventor: STRACHAN JAMES FORBES
IPC: C22C1/02
Filed: 1961-01-23
Abstract: A sintered metallic body is formed by reacting a metal powder packed in a die with a fluid consisting of or containing a metal which is to form a part of the body, the metal in the fluid being deposited in the pores of the metal powder to form the required metal composition which is then sintered.  The fluid may be a solution or vapour with the metal component in the free or combined state.  Preferably, the fluid is a vapour and specifically disclosed is the decomposition of the carbonyls of Fe, Ni, Co and Cr either singly or as mixed carbonyls.  A rigid or flexible mould is packed with the desired metal powder and the carbonyl vapour is forced into the mould at super-atmospheric pressure, e.g. 1 1/2 atmospheres at 200 DEG -300 DEG  C., the powder also being heated to this temperature.  The powder may be agitated during the decomposition process and the carbon monoxide evolved may be passed through Fe, Ni, Co or Cr metal powder to regenerate the desired carbonyl.  An example is given of the production of a sintered turbine blade having the following composition: Cr 20%, Co 16%, Ti 2.35%, Al 1.35%, C 0.07-0.1%, B 0.025%, Ni balance. The mould is filled with a pre-alloy powder of the above constituents with the exception of Ni.  Nickel carbonyl vapour is passed into the powder at 200-300 DEG  C. and the required Ni is deposited in the pores.  The moulded body is then removed from the mould and sintered at 1300 DEG  C. to 1325 DEG  C.  Molybdenum may also be included in the alloy.

Abstract: 874,412. Grinding and polishing. COMPAGNIE FRANCAISO THOMSON-HOUSTON. Jan. 27, 1960 [Feb. 3, 1959], No. 2989/60. Class 60. A method of reducing a rod 5 in cross-sectional dimension comprises placing the rod in a compartment 6 in a body 1 of glass or other suitable material and having a depth somewhat greater than the rod dimension to be reduced, placing the body in engagement with a polishing surface 3 and producing therebetween relative movement to produce a polishing action effective to wear away the material of the body and subsequently that of the rod until the rod has reached the required dimension. The rod, which may be of germanium or other suitable semiconductor material used for high-frequency transistor, is placed in the compartment 6 of the glass body which is fitted into a plastic grid 2 and placed between polishing surfaces on plates 3, 4. Polishing paste is applied to the surfaces and the grid moved to impart a back and forth and rotational movement to the glass body. After some of the glass has been worn away, the polishing surfaces act on the rod which is rotated and reduced to the required diameter. With a rod of circular or parallelepiped form having a circular bead at one end formed during manufacture of the rod, the bead causes the rod to roll when acted on by the polishing surfaces and the rod is thus polished to a circular shape. The rod may be square or rectangular in section and the compartments are then arranged to be only slightly larger than the rod. The glass body may have a plurality of components to enable a number of rods to be treated simultaneously.
