Oldham left a family of 17 children. His eldest son, Thomas Oldham (1801–1851), succeeded to his father's place at the bank. He was elected an associate of the Institution of Civil Engineers on 2 March 1841, and in 1842 he read a paper "On the Introduction of Letterpress Printing for numbering and dating the Notes of the Bank of England" (Proceedings, 1842, p. 166), and in the following year ...

An improvised flexible coupling made of car tyre pieces connects the drive shafts of an engine and a water pump. This one is used to cancel out misalignment and dampen vibrations. Rotating coupling. A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is ...

An eccentric shaft can provide the orbital motion but the scroll must be prevented from rotating, typically with an Oldham-type coupling, additional eccentric idler shafts, or a bellows joint (particularly for high-purity applications). Another method for producing the compression motion is co-rotating the scrolls, in synchronous motion, but ...
The balance lever coupling, also central buffer coupling with two screw coupling, is a coupler commonly used on narrow gauge railroads with tight curves. By swapping the pulling and pushing devices, the standard screw coupling used on standard gauge railroads became a center buffer coupling with one screw coupling on each side of the buffer.
GrabCAD, Inc. is a Cambridge, Massachusetts-based startup that created a free cloud-based collaboration environment that helps engineering teams manage, view and share CAD files. History GrabCAD was founded in Estonia in 2009 by current CEO, Hardi Meybaum , and Indrek Narusk [ 1 ] as a marketplace to connect engineers with CAD-related jobs.
