Tension spring on CD carriage

Where can I get a replacement tension spring for this CD player? The original one snapped and the carriage will not lock into place when it is in STANDBY mode. It's the one that screws onto the conveyer motor

Where is the lever that releases the carriage on the olivetti 32

There is a chrome lever on the right side of the carriage on top that should manually release the carriage by pushing down on it. If this works but there is no spring tension pulling the carriage to the left, then the drawband is probably broken. If pushing the lever down doesn't work then eithor the mechanism is broken or locked up or there is a carriage lock that need to be released. If there is a carriage lock it would be located under the carriage on the left or right side. It would be a small chrome lever sticking out the side.

Cannot unlock the carriage

There is a little lever under the carriage on the left,used for locking the carriage when in transit.Move the lever in the opposite direction,if that does not work press the Capital Lock Key then try it.If this does not work,it will be your carriage return spring having lost its tension.This is the round drum(wheel ) on the back of the carriage connected by a cord.

Have a S-M portable (5T231908X). -String Off Rewind Spool

Wind the spool clockwise at least 5 rotations. hook the string on the top and carefully let the spring take up the slack. You will need a hook of some type to pull the string through and under the carriage to hook to the other side. You may need more tension on the spring if it will not move the carriage all the way to the left. It is possible that the spring has broken inside the housing. In which case you will have to take it to the shop.

How do I release the tension on a spring loaded hinge?

If there is a cylinder on top of the hinge with small radial holes in it, you need to find a way to twist that cylinder. A special spanner wrench serves this purpose, but you can probably get away with using locking pliers (Visegrips). You will be twisting the cylinder in the direction that INCREASES the tension, so just turn it a littlle bit. That takes the tension off the door hinge (putting it on you instead). Be very careful that the spring doesn't snap free and injure you. There should be a way to then allow part of the spring to retire one rotation in the direction that would reduce the tension.

My dryer gets too hot at some points in the cycle. But I can't always get it to replicate when I'm trying to fix. How does the coil-thermostat circuit work?

Most are a snap disc style thermostat. The disc is a concave shaped disc with dissimilar metals. With the natural spring tension of the shape of the disc is overcome by the heat causing the opposing side to expand further it changes the state of the switch when it snaps the other way. Once the heat is removed the metals cool contracting them and they snap back to their original state. Some thermostats are adjustable with a spring that changes the tension so it takes more heat to overcome the tension.

On your problem: if you are testing with the dryer hose unhooked, you may just have a blockage problem in you dryer vent, that is very common and would cause your problem. Make sure your dryer vent is clear and also when you put your dryer back in it's place that you have not restricted the air flow by crushing the hose.

I have an old school "Royal Quiet Deluxe" typewriter; the carriage will not move when the letter keys are pressed or when the space bar is pressed but will move to back space or to slide the carriage back...

If there is tension on the carriage when you push it to the right, the spring is not broke or the cord..then the problem would be in the escapement would need a repairman to do this. if the carriage is loose, no tension then the spring is either broke or the cord is off or broke.
Either way not something easy....

Handle ripped off Mantis tiller

Good job on the cord replacement. Most people take the cover off the spring and then find out it is nearly impossible to get the spring tension set. I have personally repaired dozens of these cords that have been messed up by owners that did that.
If anyone has this problem, just do what this post says...remove the assembly and turn the pulley until you can get to the part of the cord that is broken...grab the end that is broken after you get it out of the opening with a vise grip and pull the cord out fully and lock the recoil spring with a vise or vise grip (but don't crush it)...then replace the cord and hold the end of the cord pull fully extended and remove the lock and allow the spring to recoil...and reinstall the assembly.
Simple, but THINK before you take the housing apart. It is REALLY TOUGH to reset spring tension properly.

Dubble den kenwood dvd player

There is a bulletin on the mech which requires 2 springs to be replaced. When you install disc the cd pushes on two sliders that push on switches to detect the position of the sliders the springs pull sliders back to original position. Sometimes the slider may stick due to not enough spring tension and possible restriction due to dust dirt etc. This would be a possible problem for your symptom .

Old remington typewriter

G'day mate, most likely cause is that the drawband is broken/disconnected. Look under the right-hand side of the carriage,you would have to tilt the typewriter on it's back. There you will see a small hook where the drawband should be attached to. If not, set the typewriter on it's feet again and move the carriage to the extreme right then looking down past the left thumb wheel you will notice a drum with the drawband attached. Rotate it until the drawband hook come into view. Get a piece of strong wire about 12 inches long,fashion one end into a hook,thread it through the machine under the carriage,from the right-hand side until it appears just over the drum. Ayyach the drawband hook to it and pull your piece of wire out to the right. You will notice the drum rotating and the increasing tension on the drawband , this good,nothing is going to snap, break etc. Hook the drawband on to it's latch and try the typing. If the typewriter's carriage moves slowly it means that there is not enough tension on the main-spring located inside that drum. Do not depair, because by removing both side plates you will see a large screw on each side of the back cover plate remove these and then you will see the mainspring drum in it's entirety. There will be a winding gear central to the drum,loosen the locking pawl and begin winding in aclock-wise direction to increase the main-spring tension. Test the carriage occasionally for tension.
When all is OK reverse all what you did before.  Cheers and goo luck from Australia....
