The perforated drum cylinder is divided into sections about 50 to 60 mm (2 to 2.5 in) wide. The filter medium is positioned into tubes between the sections and locked into place by round rods. No caulking, wires, or other fasteners are needed. 

A better way of measuring is to measure the natural frequency of vibration of a round rod of the material, simply supported at its ends (Fig. 3.4) and heavily loaded by... 

In a recently developed process, the consumable rods used in REP are replaced by disk-shaped electrodes, since such electrodes are easier to fabricate than long round rods. During atomization, a rotating consumable disk is melted at its periphery. 

An attractive simple experiment to demonstrate the damping is rotating bending take a thin round rod, bend it, and rotate it in the bent condition without applying a torsion then a clearly detectable resistance is met. The torque required for rotation is, according to a simple calculation, proportional to E2.

The company DESAGA has introduced a semiautomatic system for applying samples to the (somewhat rarely used) TLC round rods ( Chromarods ) of the latroscan... 

Ram extrusion is the only continuous process for fabrication of parts from granular PTFE powders. All the required steps of granular processing are performed in one machine called a ram extruder. The most common shapes are solid round rods and tubes. Rectangular rods, L-shaped cross sections, and other ram extrudable profiles are occasionally fabricated. 

Ramrods, n the large guo-factoTies, are made by machinery. Id the case of wooden ones, the blanks are driven through tubular cutteia, which bring them to a cylindrical form. The bon ones are cut from a round rod. For polishing, they are placed upiight in a frame which holds ten at a time, and are subjected to the action of hard-wood rubbers supplied with oil... 

The resistance to earth R as measured or calculated for a conductor buried in the ground depends upon its shape, volume and orientation in the ground. In favourable conditions the resistance should be less than one ohm. With unfavourable conditions and small sites such as the bases of pylons a value between 1 and 5 ohms should be considered. For simple shapes such as uniform rods, strips and plates, there are formulae available for calculating the resistance. For example a vertical round rod or hollow pipe the resistance is -... 

Many years ago, two pressurized water reactors were built, with the lower support plate of the eore subdivided into two plates, about three metres apart in the vertical direction and connected by an external row of round rods in traction (tie rods - TR) and by internal guide tubes for the control rod followers (cruciform) containing fuel rods, as illustrated in Figure 12-1. 

Pultrusion Unsaturated polyester, polyurethane, vinylester, and epoxy (recently, some thermoplastics such as poly(ethylene terephthalate) (PET) has been successfully used in pultrusion) Round rods, rectangles, squares, i sections, channels, dog bone profiles, comer profiles, hollow sections The resin impregnation of roving and subsequent cure... 

Short-beam shear strength n. Shear strength of reinforced-plastics materials as measured in three-point bending of a specimen whose length between end supports is about five times the specimen depth. ASTM D 2344 describes one such test for flat specimens and short arcs cut from relatively large rings, while ASTM D 4475 describes a similar test for pultruded round rod. 

When drilling small holes in round rod it is best to clamp the work securely in a V-block. Mark the hole location with a center punch. There is Fig. 22 Linkage pin, made always the danger of breaking from 1/4 C.R.S. round. rod. Make 2...
