Parallel disc system

The remaining 10 mL of blood were filtered in the CPF apparatus to obtain a control curve, and after the prescribed period of disc rotation, the blood from the parallel-disc system was transferred to the CPF apparatus for the test run. 

The cone and plate system according to DIN 53018 and ISO 3219 [27] has a measurement body with a cone like surface and a flat plate. The geometrical measures of the cone are defined by the cone radius R and the cone angle a. The ISO norm recommends a=l° and excludes cone angles of a>4 . In order to avoid any errors due to direct contact of the cone with the plate, the tip of the cone is taken off for several micrometers. Particles of a size that can cause them to be stuck in the slit between the cone and the plate have to be removed before the measurement. If this is not possible, the parallel disc system has to be used instead. 

The geometry of the measuring plate is determined through the plate radius R (Fig. 3.6) and the distance h. According to DIN 53018, the plate distance h should be very small compared to the radius R. In a parallel disc system, the shear stress is also only dependent on the radius ... 

An alternate approach to the above is to provide parallel relief valve-rupture disc systems. The valve will have a setting slightly above the normal operating pressure with the rupture disc at about a 10% higher setting. The relief valve should control minor pressure excursions, can vent material and then reseat to minimize process losses. The rupture disc would provide the ultimate safety protection. 

The determination of interaction between bodies in a liquid medium by means of measuring systems based on the principle of crossed filaments and plane-parallel discs is extremely tedious and requires the overcoming of a number of experimental difficul-... 

On the other hand, the chief advantage of the parallel disc configuration is that it can be used for filled polymer systems of extremely high viscosity and elasticity. 

The parallel-disc viscometer used for measuring the shear stress and normal stress difference of filled polymer systems is similar in principle... 

Nissan s Hypermini concept EV is a two passenger EV (electric vehicle) that can go 60 miles per hour and travel about 75 miles on a single charge. It uses a neodynium magnet synchronous motor, with a maximum output of 20 kW at 15,000 rpm, lithium-ion batteries and an inductive charging system. Rear-wheel 2WD is used with front independent struts and rear independent parallel-link struts. The brakes are ventilated discs with an anti-lock system. 

Rupture discs can also be used in pairs or in parallel with an SRV for additional safety, operational and installation cost benefits and system integrity.

At radio frequencies a medium- to low-loss material can be most sensitively examined by making it part of a resonant circuit. The Hartshorn and Ward (1936) method, for which the basic circuit is shown in Fig. 5.11, has been highly developed (Reddish et al., 1971) for very accurate measurements in the 105to 108Hz range. Here a disc specimen is held in a micrometer electrode system (see Fig. 5.6, where the specimen is represented by a capacitance Cx in parallel with a resistance Rx) and connected directly to a coil of fixed... 

For non-spherical particles of homogeneous f-potentlal (cylinders, discs, rods ellipsoids of revolution, etc.) the Induced dipole moment is different for different orientations with respect to the directions of the applied field, i.e. it acquires a tensorial nature. When the systems are sufficiently simple to require consideration of only two orientations (cylinders or rods) it is sufficient to distinguish only II and where // and 1 refer to parallel and normal orientation to the applied field, respectively. Dukhln has described the consequences for the overall polarization. ...

R M 2000, the Air Force Reliability and Maintainability Action Plan does not discuss the unique problems (and potential) of expert systems, particularly those which rely on the massive "knowledge bases" which can now be delivered on optical disc. Nor have they addressed the problems (and potential) associated with parallel processing, neural networks and "systems that learn". 

As all 30 samples are, apparently, measured in a simultaneous fashion, the system can be said to effect a parallel multi-determination —hence the generic name parallel fast analyser given by some workers to these instruments, which are even dealt with separately from batch analysers in automatic methods of analysis. However, such a difference is only apparent and, in fact, it is a typically discontinuous process, both because of the sequential measurement (with a single detector) and because there is a manual intermediate operation (the transport of the transfer disc from one module to the other).
