Title: Plain bearings and materials for making such bearings
Inventor: FORRESTER PETER GARNETT
IPC: C08J5/16
Filed: 1957-03-18
Abstract: <PICT:0848898/IV(a)/1> A plain bearing comprises a substantially homogeneous mixture of discrete metallic fibres B and non-metallic material such as plastic, the metallic fibres constituting a series of closely spaced substantially continuous metallic heat-conducting paths each extending from the bearing surface B2 to the metallic bearing housing A.  Preferably the length of at least a substantial proportion of the fibres is not less than the thickness of the bearing and the diameter approximately 0,001 inches.  The non-metallic material may be nylon, polytetrafluoroethylene or a mixture of finely divided carbon and pitch, and it may include graphite or molybdenum disulphide, kieselghur or glass fibre.  The metallic fibres may consist partly or wholly of iron and/or bronze and/or stainless steel.  The bearing surface may consist of a very thin layer of pure P.T.F.E. or pure nylon.  In one method of making a bearing, iron filaments were stirred into an aqueous suspension of P.T.F.E. and a coagulant of aluminium chloride added.  After removal of the supernatant water and further mixing, the mixture was dried and formed into bearings by moulding and subsequent sintering.  In another method, a mixture of cadmium plated copper wire fibres and fine P.T.F.E. powder were mixed in a high speed rotary mixing machine and then compression moulded.  The bearing was subsequently slowly heated to 380 DEG  C. and then slowly cooled.

Filed: 1943-06-10
Abstract: 603,218. Wet-separating. McNEILL, H. L. June 10, 1943, No. 9360. Convention date, June 20, 1942. [Class 82(ii)] In the dressing of ore in which the ore is ground in a closed circuit with a classification stage to produce a final product of flotation size, the product discharging from the grinding stage is subjected to a hydraulic classification so that substantially all the product of finely ground flotation size is directly eliminated and the oversize product left is treated for the recovery of its free mineral constituents prior to the recirculation of that product through the grinding circuit. The oversize product is separated into two grades, one containing the free mineral content and the other the middlings, the latter being reground and the free mineral so separated removed. The pulp passing directly from the grinding stage is subjected to a hydraulic classification preferably in apparatus described in Specification 603,215, to produce three separate products, the first substantially of the product resulting from flow across the classification tank and which becomes the finished product, the second a mixture of coarse free mineral and larger middlings and finally a mixture of fine middlings and coarser gangue, the middlings product being again ground and free mineral content removed in each case. The finished product may be subjected to a secondary treatment such as froth flotation, to remove the mineral content, the second grade to a jigging or gravity separation to recover the free mineral and the third grade to froth flotation or screening to concentrate the finer middlings which are then reground. The material from the ball mill 4 is passed across a tank 1 provided with a spigot department 1a and an overflow department 1b the coarse free mineral and larger middlings passing off to the jigging apparatus 2, the middlings being returned to the mill 4 and the mineral content to the smelter 8. The fine material overflowing from the classifier 1b is fed into a flotation circuit 5, the finished concentrates passing to a thickener 6 and to a filtering apparatus 7 before being fed to the smelter 8, the fine middlings or tailings passing to waste. The fine middlings and coarse gangue are subjected to froth flotation at 3, the fine middlings being returned to the ball mill 4, and the coarse gangue to waste.

[Classes 7 (ii) and 7 (iv).] During overrunning of automobile engines, an electomagnetically-controlled valve 4 is opened by a spring 5 to admit air to the induction pipe 2 to destroy the depression therein when the throttle valve 10 is closed, the valve 4 being returned to its seat by the onergization of an electromagnet 32 effected by two switches in parallel, one of which is controlled by the accelerator rod 9 and the other by centrifugal action dependent on the speed of the engine by being connected, for example, to an enginedriven dynamo 38. When the engine is running at idling speed, a flat spring 37 on the dynamo contacts with a metal part 40 and completes the circuit of the electromagnet to close the valve 4. If, before the engine speed has fallen to idling speed, the accelerator rod 9 is depressed, a projection 43 engages a flat spring 42 to complete the circuit of the electromagnet and close the valve 4. If the vehicle is provided with a brake controlled through the depression in the cylinders, the brake pedal 46, when depressed, engages a spring 44 and closes the valve 4. The ignition may be suppressed while the valve 4 is open by a relay in the electromagnet circuit which, when the valve is open, in the case of magneto ignition, earths the primary of the magneto, and, in the case of the battery ignition, opens the ignition circuit.
