Tear tape, also known as tearstrip or tear-off ribbon, is a narrow adhesive tape used to open packaging. The backing is often a narrow oriented polymer such as polypropylene but other polymers, yarns, and filaments are also used. Many tear tapes use a pressure sensitive adhesive but others have a heat-activated adhesive system.
The silver-plated wire coating cold-welds to the gold. If corrosion occurs, it occurs on the outside of the wire, not on the gas-tight contact where oxygen cannot penetrate to form oxides. A correctly designed wire-wrap tool applies up to twenty tons of force per square inch on each joint. The electronic parts sometimes plug into sockets.
The bolt drops down into receiver recess and locks on bolt closing. Tilting the bolt up and down locks-unlocks in the breech. This tilting allows gas pressure in the barrel from firing the gun to lower to safe levels before the cartridge case is ejected. For handgun design, the tilting barrel as used in the Browning, is a similar operating ...
The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin' in the U.S.), which allows for rotation between the connecting rod and the piston. Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rolling-element bearing , in order to avoid ...
The vertical aluminium block above each pair of tape reels holds the read/write heads. DECtape , originally called Microtape , is a magnetic tape data storage medium used with many Digital Equipment Corporation computers , including the PDP-6 , PDP-8 , LINC-8 , PDP-9 , PDP-10 , PDP-11 , PDP-12 , and the PDP-15 .
Richard Gurley Drew (June 22, 1899 – December 14, 1980) was an American inventor who worked for Johnson and Johnson, Permacel Co., and 3M in St. Paul, Minnesota, where he invented masking tape and cellophane tape.
A reel-to-reel tape recorder (Sony TC-630), typical of a 1970s audiophile device. Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the supply reel (or feed reel) containing the tape is placed on a spindle or hub.
Strip of permalloy. Permalloy is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content.Invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, [1] it is notable for its very high magnetic permeability, which makes it useful as a magnetic core material in electrical and electronic equipment, and also in magnetic shielding to block magnetic fields.
