How to Identify and Fix Common Vacuum Problems ?

Unlike most ballpoint pens, Fisher`s pen does not rely on gravity to get the ink flowing. The cartridge is instead pressurized with nitrogen at 35 pounds per square inch. This pressure pushes the ink toward the tungsten carbide ball at the pen`s tip. The ink, too, differs from that of other pens.
The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
During development, Fisher found that while the pressurized cartridge successfully pushed ink out the tip of the pen, it also successfully leaked uncontrollably.
How many miles do your refills write for? Fisher Space Pens will write for over 12,000 ft. or approximately 2.5 miles.
Space Pen refills contain thixotropic ink in a hermetically sealed and pressurised reservoir which allows you to write on wet surfaces, over grease, or at temperatures of – 34C to +120C and for three times longer than an ordinary ball point pen. The Ink will not dry out for over 100 years.
Debuting on the Apollo 7 mission in 1968, Fisher Space Pen has been on every NASA crewed space flight since. In fact, Fisher Space Pen now has its own permanent exhibit inside the Apollo / Saturn V Center at Kennedy Space Center, which proudly shares our history and products with some three million people a year.
Fisher Space Pen Pressurized Refills (PR series) Fits the Following Space Pen product categories: Bullet, Astronaut, Shuttle, X-750, Space-Tec, Military, Zero Gravity, Futura, Cap-O-Matic Adapters Available to Fit Parker Style Pens.
Answer: It`s to do with atmospheric pressure. There is pressure pushing into the pen which keeps the ink in place. Because it is completely airtight at the top, there`s no pressure form the other side to push it out.
The Final Frontier of Pens
The Space Pen is the perfect match for our indefatigable Expedition Edition notebook. These pens are the real deal; they`re precision-made, durable, and capable of writing in zero gravity, upside down, underwater, and at temperatures from −30 to 250°F (−35 to 120°C).
The Fisher INFINIUM pens have enough writing to last the average person 80 years. INFINIUM Space Pens are guaranteed to write throughout an individual`s entire life without refilling the ink cartridge!
The nature of gel-based ink is that it is water-proof, so it will not bleed through pages nor will it rapidly fade over time. The ink colors are pronounced and vibrant, which makes gel ink one of the most beautiful ways to write.
However, ballpoint and rollerball ink does dry out after four years if you don`t use it up. Gel ink has an even shorter expiration date, and most last between two and four years.
The bottom line is this, Heat and Humidity will make your pen write drier or wetter based on these conditions, and the hygroscopic properties of your paper. They are bad for ink sacs thus causing issues for vintage pen owners.
A: Most gel pens are waterproof, which means they won`t bleed or fade even after water spills. However, this is a great option to protect your written content.
Capacitive stylus
A capacitive touch screen uses an electrostatic field that registers contact when the field is distorted by a conductor. A capacitive stylus functions exactly like your finger by making screen contact via electrostatic field disruption.
Fisher Space Pens are great “write anywhere” additions to your arsenal, and despite a few small nits, their widespread availability and versatility make Fisher Space Pens an easy recommendation.
How Does The Fisher Space Pen Write? The Fisher Space Pen writes smoothly with quality ink, a deep black hue, and none of the stickiness you might experience with a cheaper alternative.
Rather than communicating with a touch screen through physical pressure, the Bluetooth stylus depends on wireless information transmission to register contact. The Bluetooth stylus functions similarly to the capacitive stylus but offers more additional features that cater to the creative user.

My garage door opener will start to close then stop and go back to the open position. If I put pressure on the door as it is closing sometimes it will close all the way and sometimes it will return to the open position. Can you help me. Thanks
ANSWER : Sounds like the pressure sensor is being tripped – this is a safety feature on most makes in the last 10 years.
Find the make/model of your device and it probably has some knobs on the main unit to adjust.
For example, on the Chamberlain Power Drive 3/4 HP Chain Drive Garage Access System model PD752D:

I have a Dyson Animal upright (purple). I took it apart to clean the cyclone chambers. When re-assembling the bottom closed before the opening rod was inserted. I can’t get the opening rod installed with the bottom opening closed. How do I open it? Thanks.
ANSWER : I looked in our DC07. I would try removing the top again and getting a long dowel or the opening rod, insert it down into the unit and PUSH. The opening rod opens the latch by pushing it, not pulling it. Here are some pictures of the latch. Top pic is in the unlock position. Bottom is the normal position.
I hope this helps.

After a brief power outage my Marantec 4700 garage door opener has problems opening/closing. When opening it stops at the fully open position and the lights blink, when closing it automatically reverses just as it fully closes and then the lights start to blink again. I checked for obstructions and tried to reset the limits of travel per the manual, it still does the same thing. Any ideas on what to try next?
ANSWER : This is not a sensor issue, I have a similar problem, sensors work fine, garage door is still fully functional, all operations, including safety sensors work properly, just the overhead lights flash. I suspect there was damage to the power board due to a power surge, going to order a replacement to see if it works, will let you know how it goes.

Placing the handle of my Dyson DC07 into its upright and locked position causes the beater bar to stop turning. It will not start turning until the handle is first lowered to the working position and the Carpet/Bare knob is moved to the Bare Floor position and then back to the Carpet position. Then the beater bar turns until the handle is placed into the upright position. What might be the problem?
ANSWER : Hi its Darran at Dyson.
The brush control is designed to switch the brush bar off automatically when you stand the machine back into the upright position. It is designed this way to protect any delicate floor surfaces when you have the machine switched on and upright and when you are using the hose.
If the brush control should be in the centre position and move forward to the “on” position when you release the head. If it is not doing this, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

My Dyson DC14 Animal doesn’t have the suction it used to. The piece in the back on the bottom – a flap it appears – stays open now, causing the machine to make a louder noise than usual. At first, if I put my hand on the flap opening it would close, allowing for normal suction. Now, it stays “open” permanently”, causing the loss of suction.
ANSWER : Hi its Darran at Dyson.
Having had a look at a DC14 here, I am unsure as to the part you are referring to. So that we can help you further, please contact our Helpline free on 0800 298 0298, between the hours of 7am – 10pm, 7 days a week.
Please have your machine with you when calling.

Now it won’t com[pletely close! The plastic clasp is intact. Is there anything I can do before having to haul or send it for repair?
ANSWER : Your supposed to take out the plastic part that holds the bag but the way this unit is designed the lid will not close unless everything is inthere correctly so just make sure evverything in inserted correctly and keep trying! DO you still have your bag holder?
