Abstract: An aluminium alloy made of consolidated rapid-quenched aluminium alloy powder by using an improved metallurgical method basically comprises, by weight percent, less than 30% silicone, less than 8% iron, less than 7% copper and less than 0.2% oxygen, the balance being substantially aluminium. The consolidated rapid-quenched aluminium alloy powder has features that it contains less than 0.2% oxygen, and the material made from the rapid-quenched aluminium alloy powder has a high limit compressibility factor, rate of reduction and tensile strength. Thus the aluminium alloy material obtained is suitable for structural members such as pistons for internal combustion engines.

Abstract: The crankshaft of an engine is supported by bearing caps mounted on journal walls of a cylinder block and a bridge interconnects the bearing caps. Oil passages in each bearing cap lead from the bridge to each crankshaft journal bearing at a laterally offset location rather than on the cylinder axis. A longitudinal main gallery in the bridge supplies oil to the passages and is laterally offset even further to that side. A supply passage in the bridge and one bearing cap at one extreme lateral side supplies oil from a pressurized oil supply passage in the cylinder block to that supply passage in the bearing cap.

Abstract: An internal combustion engine has an integral cylinder block, crankcase and sump structure made in two halves 1, 2. The material of the halves is chosen for lightness. The pressure pulsations in the cylinders are taken by long steel bolts 14, 15 which extend from the top of the cylinder head to a bearing structure comprising yokes (steel clamping members 8, 9 clamped together by traverse fasteners 12, 13) holding together the two main crankshaft bearing housing halves 6, 7 which are formed integrally with each half of the integral engine structure. The integral halves do not have re-entrants and can be produced simply by casting, pressing or moulding.

Abstract: A reciprocating type gas compressor comprises a hollow frame or housing having spaced apart end walls, a motor-driven crankshaft disposed within the housing and rotatably mounted on bearing assemblies on the end walls and connecting rods connected to crank pins on the crankshaft for driving pistons located within the housing. The crankshaft comprises a drive shaft at one end and a pump shaft the other end, both extending along a common axis of rotation. The crankshaft also comprises a pair of axially spaced apart counterweights located between the two shafts and a crank arm or link located between the counterweights. A crank pin extends from each counterweight to the link along a pin axis which is parallel to and spaced apart from the common axis of rotation. Each bearing assembly has a hollow cylindrical inner race which is friction-fitted on a shaft at an end of the crankshaft and abutts the side of one counterweight. To enable removal of each friction-fitted bearing assembly from its shaft without damage thereto, a pair of threaded bores extend through portions of each counterweight and the bore axes are parallel to but located on opposite sides of the common axis of rotation and each bore is aligned with the inner end surface of the inner race of the associated bearing assembly. Each threaded bore accommodates a long jack screw which is temporarily rotatably inserted thereinto so as to engage the inner race and force the bearing assembly off of its shaft for servicing or replacement.
