    Highly Unusual Doubled Up Earthing Wires on UK Domestic Installation

    I have recently bought a 1960's bungalow in the UK which has a highly unusual (but probably safe) 240v electrical wiring arrangement. I thought I'd check with some experts before ripping 50% of it out. I have had no luck polling local electricians who either don't know or don't want to get...

    Phosphor Bronze Custom Bush: Material Selection

    I am designing some custom bushes which must be a phosphor bronze material or very similar. I have a copy of "BS EN 12163 Copper and copper alloys — Rod for general purposes" in my hand. The choice is bewildering. The requirements are: No lubrication. Room temperature low humidity environment...

    Free Simple Wireframe 3D Mechanism Animation

    I have a very simple mechanism with a complex 3D motion. It is a network of 9 beams with rotating joints. The motion is cyclic. I have calculated the motion of all of the joints and generated a time history of coordinates for each one in a text file. What I would like to do is display the...

    DIY Battery UPS for 80W Central Heating Pump

    I am trying to source a 230v UPS from 12v battery backup to keep a gas central heating system running in the event of a power cut. I need about 80W for 10-20 hours, maybe another 50W for minimal lighting. I just can't find a small system to do this - it seems on net searches to be either very...

    Easy Definition of Node paths for XY plots

    Does anyone know how to: a) Define node paths for use in subsequent X-Y plots in a way which is more convenient than picking every node on the path (I have a lot of nodes on each of 4 paths) b) Save the paths once defined so that when I come back into CAE next day the paths are still there. I...

    Ultra Low Vacuum Adhesive

    I am trying to find a sealing material or an adhesive which has a permeability about 10x lower than butyl rubber. I am trying to hold a vacuum of 10-4 mbar/torre for 1-5 years and I know from my geometry that butyl rubber won't do the trick. 10-4 torre is about as good as you will get without...

    Whatever happened to FEMVIEW?

    I used to use FEMGEN, ABAQUS and FEMVIEW a lot, many many moons ago. Does anyone still use FEMGEN or FEMVIEW these days? gwolf
