    concrete barge design - need tips and background on this

    There was a series of concrete freighters built at Hog Island in Philadelphia during WWI I think.

    automated wrapping pointers needed

    Wolfbag; Your description is kind of skimpy on details. Can you see through the wrapping material, etc? I'd start out looking at focused photoelectric sensors, either laser or a fine fiberoptic cable to locate cylinder and wrapper edges. A little more sophisticated and flexible approach to...

    Cleaning clothes by blowing 6 bar air

    Costas; This bit of trivia may be a little off the mark, but be aware that metal chips, in the eyes or imbedded in the body, as might be caused by high pressure air, are a real hazard to a patient receiving a medical MRI scan. The patient may not even be aware of the particles presence, but...

    First Use of Threads

    I guess thgat the thread chase makes sense, but how do you get the needed accuracy into the chase? JC

    Positioning a rotating basket precisely to the same position each time

    I'm sure that this is much too late to do you any good, but..... I think you mentioned using an inductive proximity switch on the lid which indicates that it is metallic. Inductive proximity switches are also available in analog output types and are very accurate in measuring distance to a...

    Get me on track in/re trains

    https://hosta.atsc.eustis.army.mil/cgi-bin/atdl.dll/accp/tr0670/text.htm This is probably more than you want to know but there is a section on rail gage that says it might come from Roman chariot ruts, but that no one is sure.

    First Use of Threads

    Y'All - I'm from Southern Massachusetts :-) Out of the clear blue sky I stumble on a thread that reminds me of something I haven't thought about in years. I asked this question of the curator of a machine tool museum in the Massachusetts/Rhode Island Blackstone River Valley. This is the...

    Turck Sensors ?

    Pumpdesigner; You are absolutely right. Worked with a group of engineering geniuses who weren't terribly well founded in the operating conditions of the "real" world. They designed a programmable controller that was sold to a manufacturer of checkout stands. They were okay except that...

    Bearing noise due to overgreasing ?

    Although it sounds like this is not the problem it might come in handy in the future. I was taaught many years ago that overgreasing a ball, and presumably a roller, bearing retards the movement of the ball/roller in the race. This causes the balls or rollers to "collide" with each...

    Problem with shot coupling?

    What has the actual shot from the coupling looked like after the failure? Has it been replaced over the last twenty years?

    Source of Large Motor Vibration

    Buscorio; You mention in your original post that there are a number of motors exhibiting the same behavior, but one is worse than the others. You also mentioned that these motors have been rewound because of an original problem. (I have to admit that my head is spinning with the amount of...

    Turck Sensors ?

    Spent 15 years with a division of Honeywell that competed with Turck in other types of sensors such as photoelectrics and inductive proximity sensors. I honestly never remember any "buzz" about poor design or quality, at Turck, in the areas that we were concerned with.

    Get me on track in/re trains

    Not for nothing.....and apropo(sp?) of nothing....another railroad oddity that may be of interest is joint spacing. Most countries stagger rail joints from one side to the other. This results in the hypnotic "clickety clack" that we are all familiar with. In Russia or the Soviet...

    Use of VFD output side contacter for E-stop

    Suggest you check up on the OSHA required gear and circuitry for operator safety, if op safety is a consideration.

    motor stopping rapidly during a fault

    Does this chiller have an unloader valve that may not have functioned properly?

    Mechanical Analog Computers

    In the late 1960s, while attending naval OCS I watched an old naval training film on analog fire control computers. It was really fascinating. Have no idea of the title anymore, but it was an animated version of the information provided in the PDF file that someone posted on the Ford computer.
