    Looking for someone with experience to help develop an apparatus that allows multiple users to use one steam boiler. Must have mechanical knowledge working with dry steam or superheated dry steam. Details, I'm looking to design an electric powered single boiler unit that will produce "Superheated dry steam", with the ability of many (human) operators to clean different items at once (example: instead of one operator in a hospital cleaning/Sanitizing 1 item at a time, to have a group of operators cleaning multiple items at one time without loosing the efficacy of the heat/pressure. The steam delivery hoses will need to have the ability to reach 20-30', so we can position the operator safely, with controls on each delivery nozzle. This project is from design to prot...

    Wall Flask 6 天 left

    I have a product I'm trying to get manufactured and the company that I'm going through gave me a ridiculous quote to take my rough draft design and turn it into a professional design that is ready to be manufactured. The product is very simple its a water bottle for your wall basically that consists of a hard plastic bladder with a lid and a camelback-type hose and mouthpiece that comes out of the bottom. I would also like to have an indention in the back that can hook onto a command strip hook. The flask will hang on the wall via the command strip hook. I will attach my rough draft in a .stp file.

    I am working on Non-Isothermal PE-100 pipe extrusion. I am applying cross law for viscosity dependence on shear rate and Arrhenius law for viscosity dependence on temperature in direct extrusion at POLYFLOW. When i run, it shows solution is not converge. When I change the viscosity to be not temperature dependent, then the solution can be converged. So there is any way to make it converge and in the same time take the temperature into account to determine the viscosity? where I am wrong? I am struck here. Kindly help me.

    We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

    We have a vacant lot under contract in Palm Harbor, FL and there is a drainage pipe in the middle of it. We learned that it is the drainage pipe for all the houses on the street. The county said its only buildable if it can be moved, directly from the DRS Manager, "Unless they have a civil engineer design a new stormwater management system for the subdivision, the lot remains undevelopable." So, we would like to see if this is possible and if so, what the approximate cost would be. Thank you.

    Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.
