There are difficulties of detecting defects in axial canal because of solid sediment layer of 1. 2 mm thick on the canal surface. When using known defectoscope devices a preliminary labor-intensive mechanical treatment of the axial canal surface is needed. The experience of application of different methods of rotor axial canal control in multifunction automatic device ROTOR - K has pointed to the fact that the most effective method is eddy current one [1]. All the dangerous cracks were just detected by the eddy current method, the part of the cracks were not... 

A wet-process plant maldug cement from shale and hmestoue has been described by Bergstrom [Roc/c Prod., 64—71 (June 1967)]. There are separate facilities for grinding each type of stone. The ball mill operates in closed circuit with a battery of Dutch State Mines screens. Material passing the screens is 85 percent minus 200 mesh. The entire process is extensively instrumented and controlled by computer. Automatic devices sample crushed rock, slurries, and finished product for chemical analysis by X-rav fluorescence. Mill circuit feed rates and water additions are governed by conventional controllers. 

This senses the speed of the machine and performs extremely fast and accurate adjustments in the fuel supply to the PM. In turn it regulates the speed and the output of the PM within predefined limits, depending upon the droop of the PM. The governor may be a mechanical (manual), hydraulic or electronic (automatic) device. 

Actuator An automatic device providing valve or damper control of fluid flow by means of an electrical, hydraulic, or pneumatic motor. 

Control A manual or automatic device allowing the regulation of pressure, temperature, and moisture content of volume flow of a system. 

Particle counters A manual or automatic device used to determine the particulate concentration of a given gas sample. 

Enticements to involve the retail customer base, as well as the industrial sector, in the solutions desired became popular. Interruption of large commercial load, a provision by contract, had long been used to offset capacity shortages. Interest in this method mounted. In addition, retail customers were provided enticements to cut load, either by manual participation or by automatic devices. These enticements will like continue into the future. 

An automatic device that removes condensate and noncondensable gases (such as air) from steam. 

Engine Overspeed Stops. Every compressor prime mover, except electrical induction or synchronous motors, shall be provided with an automatic device that is designed to shut down the unit before the maximum safe speed of either the prime mover or driven unit is exceeded. 

The most important applications of Ca " ISEs are in biomedical practice, especially in the determination of ionized calcium in serum. A pioneer work in this field was that by Moore [149] (see also [110,111]). At present the Ca ISE is used in the solvent polymeric version in a number of automatic devices for determining ionized calcium in serum, usually with periodic recalibration of the electrode and thermostatting to 37 °C. It should be noted that ISEs measure... 

Automation has been applied for a number of years in process control instrumentation, but the major impetus to introduce automatic devices into laboratories stems from three sources (1) the introduction of the continuous-flow principles as outlined by Skeggs [1] (2) the general demand for clinical chemical measurements, which represents a ready and sizeable market for instrument companies, and, more importantly, (3) the abihty to handle large volumes of data and package them in a form suitable for presentation to analysts and customers, through the use of mini- and micro computer systems hnked to a control computer. 

A dilatometer consists essentially of a glass tube (the body ), containing the reaction mixture, to which a straight capillary tube is attached (usually, but not always, vertical). The movement of the meniscus of the reaction mixture in the capillary amplifies changes in the volume of the reaction mixture and is measured, as a function of time, with a cathetometer or by some automatic device. Dilatometry has been used for a very long time because it is simple, cheap, convenient and can be made very accurate. 

The evacuation of nitrator should proceed with the greatest possible speed and immediately after the respective valves are opened the personnel should leave the nitration room. Good discipline and the ability to think and act quickly are essential in the employees (more especially in the nitration foreman). In order to facilitate operations at times of crisis, various automatic devices are used to ease the manipulation of the valves. When a single lever is touched or a single button pressed these devices simultaneously actuate, for example,... 

Bombs, Robot Missiles carrying warheads, such as the Ger V-l(see PATR 2510,p Ger 213) or a flying bomb, launched from the surface and directed in flight towards its target by an automatic pilot or other automatic devices Ref Glossary of Ord(1959),44... 

Flow rate range is rather large. A pump is capable of delivering 0.001-9.99 mL/min in analytical mode. Some pumps are also capable of delivering up to 50 mL/min in preparative mode. In micro LC, the mobile phase is usually delivered at very low flow rates (0.1-100 yu,L/min). All pumps are equipped with an automatic device that stops the motor when pressure reaches a given value.

Another advantage of automatic devices, and a very important one when many strips have to be evaluated, is the possibility of adapting an integrator to the reading mechanism. It supposes the dropping of theoretical vertical lines for isolation of fractions. 

Column chromatography yields quantitative results even for constituents present in only small amounts (with the exception of tryptophan, methionine, and glutamine, in which cases the recovery is not complete see below, (b) Dowex 50-X4 columns). It lends itself also to extraction on a preparative scale for further analysis of a particular constituent it does not require previous desalting of urine. The major inconvenience of ion exchange column chromatography for routine analyses is that the technique is elaborate and time consuming, and requires experienced personnel and expensive equipment. Recent developments, however, have allowed for considerable reduction in time consumption, and the latest completely automatic devices open the way to serial analyses. 

The stated variability is certainly within acceptable limits, as are the recovery values reported. It would seem likely that there is room for this rapid, accurate automatic device for chloride determination in many laboratories. The cost of the silver wire reagent is low. There is some need for cleanliness and proper care of both the generator and indicator electrodes. 

This is the preferred option. If the device can deflate at a constant rate of 2 to 3 mmAec, one can do simultaneous readings. Record the BP by the auscultatory method as the automated device takes the BP To be certain the automatic device inflates high enough to get an accurate pressure, you must obtain the palpated systolic pressure and then ensure that the automatic device inflates at least 30 mm above that. Then listen as the automatic device deflates and record the systolic and diastolic pressure you hear After you have recorded your reading, record the reading from the automated device. This should be done at least three times and then analyzed as in Table I. 

For this reason an apparatus for determining thermal stability on the basis of electrical resistance change (3) was designed, and an automatic device for exposing PVC strip specimens to a gradient increase of heating time at the test temperature was built.

Streaking is used primarily in prep TLC, and automatic devices are also available for this purpose.21 This process has the same objectives and requirements as spotting, but it permits larger amounts to be applied and uses the entire bed (no empty spaces between spots). 

As robotics come into greater use, these automatic devices will undoubtedly become incorporated into a fully automated TLC process. 

The electrical circuitry in the gauge leads to easy adaptation to recording, automatic devices, and computer sensing.
