Title: Improvements in or relating to processes of manufacture of composite bearings
IPC: B29C45/14
Filed: 1944-09-29
Abstract: 584,004. Moulding resilient composite bearings, oil seals &c. GODFREY & PARTNERS, Ltd., SIR G., MILES AIRCRAFT, Ltd., and BURGER, F. E. Sept. 29, 1944, Nos. 18712/44 and 23917/45. [Class 87 (ii)] [Also in Group XXII] In making bearings, oil seals, flexible shaft couplings and like machine parts consisting of a number of elements 12 supported close together on a resilient support 13 which keeps the elements in position and transmits stresses to other parts of the machine, these elements 12 are connected in correct relative relation by an extension 16, Fig. 3, which holds them while thermosetting plastic material is forced into contact therewith and bonded thereto under heat and pressure, the extension 16 then being machined away. In making a bearing liner, as described in Specification 578,318, [Group XXXIV], a phosphor bronze ring 16 with longitudinal and annular external grooves 14, 15 is arranged in a mould consisting of a core 18, Fig. 4, and top and bottom recessed members 23, 17 adapted to hold two semi-annular parts 19 and a steel annulus 11 within them, slightly spaced from the elements 12 which are supported on the core 18. Uncured synthetic rubber or other plastic material is placed in a groove 25 in the member 23, an annular piston '27 is placed thereon and the whole placed in a steam-heated hydraulic press which forces the plastic through the ducts 26 into the space 13 and then cures it. After removing the members 23, 17 the parts 19 can be separated by inserting a tool into recesses 21, 22 provided for this purpose. The composite ring is then turned to remove the extension 16, make the exterior of the ring concentric with the inner faces of the now-separated elements 12, and smooth the ends. In a modification, e.g., in making a split bearing, Fig. 6, the extension may take the form of a sleeve 37, Fig. 10, at one end of the elements 36 which are separated by slots 39 into which the rubber is forced and may have annular oil grooves 38, Fig. 6, which do not cut right through the metal. The external ring 35 has flanges 32, 33. After moulding, the composite ring is mounted in a chuck by its sleeve 37, turned and parted off. Finally it is sawn into two parts. In another modification the inner ring 55, Fig. 16, has longitudinal and annular external grooves as in the first modification but the outer ring 58 has longitudinal internal grooves 59 so that, after moulding, and boring and turning to remove the inner and outer ungrooved portions 16 and 58 the composite body can be parted off at the lines 70, 71 to form three oil sealing rings with outer and inner segments 52, 12, Fig. 12, as described in Specification 583,348, [Group XXVI]. Conical bearings, thrustwashers and the like may be made similarly.

Title: Improvements in or relating to the manufacture of nitrogenised cast iron alloy articles
IPC: C23C8/02
Filed: 1932-07-05
Abstract: In the manufacture of nitrogenized iron alloy articles, a uniform physical structure in which free carbon in very finely divided form is disseminated throughout the surface layers of the casting is produced in the casting either by controlling the casting process or by subsequent heat treatment, and the casting is then nitrogenized. The molten metal may be cast centrifugally or may be superheated prior to casting or may be subjected to a prolonged heating at above the normal casting temperature.  If the metal is cast in the usual fashion, the casting is either annealed at about 900 DEG  C. and then reheated to 875 DEG  C., quenched to about 200 DEG  C. and reheated to 700-750 DEG  C. or simply quenched from 950 DEG  C. and then reheated to a temperature below the quenching temperature.  The castings contain 2-3.5 per cent of carbon and 1.4-4 of silicon, part of which may be replaced by aluminium, nickel or titanium, and may also contain one or more of chromium, molybdenum, vanadium or tungsten in amounts of from 0.5 to 3.5 per cent.  Further alloying elements such as copper, cobalt, manganese, or zirconium may be added to the alloys. Specification 287,156, [Class 72, Iron &c.], is referred to.
