Time-train rings

It is identical with the M55 series, except that M55 models have a booster assembled to the fuze. The fuze consists of three major parts 1) A closing cap or head (A) contg the SQ impact element (B, C, E) and the time-action plunger (F) 2) Two time-train rings,...

Properties Readily ignited by flame. Evolves about 700 calories of heat and 300 cc. of gas per gram. Various grades, specified by fineness. The fuze powder for loading time-train rings is the finest grade (passing a 140-mesh screen). 

Uses For safety fuses (Miner s fuse, Bickford fuse). For time-train rings and combination fuzes. (In mechanical devices the spelling is z.)...

Fuze, Time and Superquick (TSQF). A. fuze which is activated by the burning of a powder train (ring or column) preset to the desired time and which contains an additional device designed to cause instantaneous activation as a result of impact (Excludes Fuze, Bomb Fuze, Mine and Fuze, Hand Grenade)... 

For a [2]catenane containing a smaller bipyridinium ring in a bigger ring made of four hydroquinones in acetonitrile at 80 °C it was shown [119] that the former moves around the latter 14 x 103 times a second and self-revolves 9 x 106 times a second. In the [3]catenane shown in Fig. 40, where one more bipyridinium ring is incorporated, the two smaller rings were found to move around without collision 10 x 103 times a second as though they were trains as a molecular scale [119]. 

Figure 6.18 Stop-flow 2D WET-TOCSY spectrum of 3,5-dichloro-2-hydroxybiphenyl. Protons (H4.H6) of the chlorinated ring can be identified due to the magnetization transfer between the signals at 7.23 (H4) and 7.41 (H6) ppm. Conditions spectrometer, Bruker DRX 600 probe head, 4mm z-gradient LC probe. 13C decoupling was applied during the WET-pulse train and acquisition. The spectral size was 8k x 512 data points, with 16 scans per increment, and a 64 ms TOCSY mixing time...
