fig.2: Horizontal slide saw with open loop force flow fig.1: pivot saw with a close loop force flow. When a circular carbide-tipped saw blade enters or exits the material, only one tooth is cutting. The fluctuation of the load, when the tooth enters and exits the cut, induces vibrations and requires a very stiff gear box and machine.
In the former the end is doubled before it is finally tucked. To untie, all that is required is a smart pull on the end of the rope, which withdraws the loop and causes the knot to spill instantly. A slip knot may be tied in the bight as readily as in the end, but the load must be on the standing part of the knot only.
Sliding mode control forces the system trajectories into this subspace and then holds them there so that they slide along it. This reduced-order subspace is referred to as a sliding (hyper)surface, and when closed-loop feedback forces trajectories to slide along it, it is referred to as a sliding mode of the closed-loop
Cryostats are used in medicine to cut histological slides. They are usually used in a process called frozen section histology (see Frozen section procedure). The cryostat is essentially an ultrafine "deli-slicer", called a microtome, placed in a freezer. The cryostat is usually a stationary upright freezer, with an external wheel for rotating ...
When another blackout hits, Mullen’s team gets to work with diagnostics while he and his wife, Sheila (Joan Allen), contend with a group of “extremists” who’ve gathered outside their home.
As the milling cutter enters the work piece, the cutting edges (flutes or teeth) of the tool repeatedly cut into and exit from the material, shaving off chips (swarf) from the work piece with each pass. The cutting action is shear deformation; material is pushed off the work piece in tiny clumps that hang together to a greater or lesser extent ...
The benefit of a common whipping is that no tools are necessary and the rope does not need to be unlaid. The problem is that it will slide off the end of the rope with little provocation. Other whippings avoid this by interleaving the whipping with the strands of the rope and creating friction with the strands to avoid slipping.
A cue based on a cut will include a slide tray advance, unless designated an "alt" (see Alternate). Hard Cut – By first using the slide projector shutter, the transition between two projectors can be made faster than by controlling the lamp on and off. A visible "shutter chop" can be seen, depending on the shutter speed of the projector involved.
