Here, George Davis, Design Engineer of Coda Systems, talks us through a new product which is changing the game in connector technology. A cow-herding video game could help us not only interact more effectively with artificial intelligence, but even improve the way robots move in the future. Launching in summer 2025, the UK’s first all ...
Core plugs: bonded or threaded, it’s the seal that counts
When an engine block or cylinder head is cast, the process involves the use of sand to form the internal coolant passages and lubricant channels, and this sand is subsequently removed via external holes or 'cores' in the casting. Clearly, these have to be capped to seal the internal cavities and achieve a totally leak-free structure - hence the …
The difference between calibrated orifices and holes
Dec 2, 2022 · The Lee Company sells calibrated orifices by Lohm rate, a measure of flow resistance defined such that a 1.0Lohm restriction will permit a flow of 100 gal/min of water with a pressure drop of 25 psi at 27°C. Higher Lohm rates correspond to lower flow rates. The relationship between C and Lohm rate, L, is: L = 0.67/ (d 2C).
Eaton Corporation - How to choose a counterbalance valve
Basic counterbalance application. Standard counterbalance valve (Eaton 1CE) For most applications, the most cost-effective solution is to use a basic load-holding valve such as the Eaton 1CE, which is suitable for use with static or dynamic loads when trying to stop a load from running away. A common example is a cherry picker, where the load ...
'DLR': raising functionality while lowering cost and complexity

Setting solar sail – Deployable propulsion for satellites
The full-size booms under test are intended for a solar sail. Solar sails convert sunlight into thrust with the help of reflective membranes and can be used as propulsion for satellites. The planned sail size of 500 square metres will be able to generate a thrust of approximately 0.5 grams (for comparison, a single peanut weighs approximately 1 ...

How to implement hardware debounce for switches and relays
A switch is a component that can “make” or “break” an electrical circuit, thereby interrupting an electric current or diverting it from one conductor to another. There are many different types of switches, including toggle switches, pushbutton switches, micro and limit switches, and relays. All have one thing in common: they bounce.
