More recently, a system using greaseless valves and a magnetic lifting mechanism was used (135), but no differences were found in the behavior of solids activated in either type of reactor. The activation procedure consists in the evacuation (10 s Torr) of the system at the position L at 430°C for 8 h ...

In addition to powered industrial trucks, there are other devices designed to move product. Overhead cranes, hoists, conveyors, and magnetic lifting devices require special training. For some employees, this may be the first time they have seen this type of equipment in operation. Special safety precautions must be discussed with employees prior to working near these jobs. Follow manufacturer guidelines.

A measurement procedure has been developed that allows to determine the mass of the inclusions as well as their locations with respect to radius, angle, and depth (2). For the depth determination use is made of the approximate 1/R dependence of the magnetic field strength from the distance R to the inclusion When in a first measurement at a small lift off an inclusion is detected, the measurement is repeated at an increased lift off From the signal ratio the depth can be calculated or seen from a diagram like fig. 5a which was generated experimentally. After that, from calibration curves like fig. 5b the absolute value of the signal leads to the mass of the inclusion.

Variable Flow Rate Conventional variable clearance volume and valve lifting devices are impracticable at high pressures and, should it be necessary to vary the flow rate, use has to be made of variable speed electric drives or magnetic clutches. Integral steam and gas engines have been used and Burckhardt (168) developed an hydrauhc drive to provide an integrated variable capacity machine, but its efficiency is less than that of a straight mechanical drive.

A simple separator used to recover the magnetic particles consists of a series of disks mounted on a shaft. Each disk has a number of permanent magnets mounted flush with the surface at its perimeter. The disks rotate into and out of the Hquid containing the suspended magnetic material and lift the magnetic particles out of the stream. The magnets are then scraped clean (Eig. 10). Very low residence times are needed for removal of the particles compared to settling or flotation (142). 

Cross-belt magnetic separators are based on the same principle as lifting magnets. Although these units have relatively low capacities, the same unit can produce selective separations with different products by using different pole gaps and field strengths. (See Fig. 19-42.)... 

Dry magnetic drums can be designed to perform as lifting magnets or pulleys. Magnetic drum devices have stationary magnets pulley drums rotate. Other schematics of possible arrangements are presented in Fig. 19-44. 

American physicist Joseph Henry develops a coil magnet that grows stronger as more wire is wound around an iron core. He succeeds in lifting more than a ton of metal. Thermostat is invented. 

These seals separate two parts of an apparatus, and they can be broken by a slight mechanical blow. The simplest type is illustrated in Figure 47, //—the tip is broken off by a piece of iron, usually enclosed in glass, dropping under gravity. This weight is moved and lifted with a magnet. 

The spin state of a paramagnetic system with total spin S wiU lift its (25 + l)-fold degeneracy under the influence of ligand fields (zero-field interaction) and applied fields (Zeeman interaction). The magnetic hyperfine field sensed by the iron nuclei is different for the 25 + 1 spin states in magnitude and direction. Therefore, the absorption pattern of a particular iron nucleus for the incoming synchrotron radiation and consequently, the coherently scattered forward radiation depends on how the electronic states are occupied at a certain temperature.
