Circular Cutter

Inside Circular Cutters. These units consist of a 360° shaped charge expl, contained in a hermetically sealed, either rigid or inflatable housing, and are used for severing underwater piling, pipe, caisson, etc (Fig 2)...

Naturally, leather absorbs some liquid water but mainly is water resistant. The leather industries do not claim that it is waterproof. So-called waterproof leathers are finished with water repellent agents such as organo-silicon, fluorocarbon and so on. Water absorption of leather can be tested by a static absorption method (ASTM D1815, 2000a). Cut the conditioned specimen with a circular cutter. Measure the diameter and thickness of the specimen. Calculate its volume in cubic centimetres. Weigh the specimen to the nearest 0.01 g. Immerse the specimen in distilled water at 23 1 °C in ahorizontal position with the grain side up. Leave the specimen immersed for a period of 30 min. At the end of immersion, take out the specimen and blot the surface of the specimen with filter paper to remove excess water. Weigh the specimen immediately to the nearest 0.01 g. Calculate the amount of water absorbed by the specimen ... 

Elanged Construction - This construction technique (to the extent It does not compromise technical specifications on leakage) will reduce exposure by decreasing the time required to disconnect components and by reducing the use of dismantling methods which spread contamination (e. g., power hacksaws and circular cutters). 

Stress-Strain Data. Tensile tests were made with an Instron tester at some seven crosshead speeds from 0.02 to 20 inches per minute at five or six temperatures from 30° to —46°C. The tests were made on rings cut with a special rotary cutter from the circular sheets of the elastomers. The dimensions of each ring were determined from the weights of the ring and the disc from its center, the thickness of the ring, accurately measured, and the density of the rubber. Typically, the outside and inside diameters were 1.45 and 1.25 inches, respectively, and the thickness was about 0.085 inch. The test procedure used is described elsewhere (11), and the cubic equation, eq 4 in ref. j 2, was used to compute the average strain in a ring from the crosshead displacement. 

The Cup-Plate or Well Procedure. This procedure is similar to the cylinder-plate system except that wells are cut into the agar with cutters capable of cutting uniform, completely circular wells. As with the cylinder-plate assays, the wells are filled. Zones are measured after incubation and the concentration determined utilizing a comparison with a standard response line. 

Fill a small iron crucible about one-half to two-thirds full of magnesium powder. Bore a pinhole in the iron lid and then place the lid on the crucible. Lute the lid to the crucible with wet asbestos pulp and close the hole with the same material. (If a lid is not available, twist the crucible on a piece of asbestos board like a biscuit cutter until a deep groove has been cut in it and then lute it to the crucible as before.) Dry the crucible and its contents in an air oven or on the hot plate and when they are dry pierce a small hole in the asbestos plug with a pin. Place the crucible in a circular hole... 

Preparation of the cartridge. Make circular pieces of black powder pasted paper(pasted on one side only) with a wad cutter. The diameter is about the same as that of the inside diameter of the mortar. Take two of them and make a bag by pasting them together at the edges, placing the pasted black powder outside. Charge about 6 g of black powder grains in it and seal it with paste(Fig.127.(C)). 

A correct alternative to the one-dimensional cross-stream slice with parallel sides is a cutter (sampling tool) that rotates around an axis in a circular fashion. In such a case, the cutter must have a radial shape, that is, it must be wedge-shaped, with the cutter edges converging towards the axis of rotation (Fig. 4). This design ensures that material on the outside of the arc, where the cutter moves faster, has the same chance of being in the sample as material near the center, where the cutter moves more slowly. 

The flret process is called cupping which is done with a dic working Inside a cutter. A eheet of copper 8 wide la fed under me cutter by the attendant and a circular blank in diameter is cut, and then pushed through a flaring-mouthed die hy the punch, thus making it into a cup-shape... 

Wad. 1, Fire arms.) The wad of a gun is intended to hold the charge in position at the rear of the chamber, or to prevent windage. In small-anus it is usually a disk of felt, punched by a circular wad-cutter. An old felt hat furnishes excellent wads. Plugs of paper, oakum, or cardboard are also used.

A rotary table, Fig. 11.13, is used where part of the surface being machined is of a circular nature. In this case, the table is moved to bring the workpiece in the correct position under the cutter. The workpiece is then rotated past the cutter to produce a circular profile. 

Rotary blade knife ( Pizza Wheel type cutter) — is circular and rolls over the material (see Figure 9.13). Rotary blade knives are used in single-ply cutters to cut the contours of the components. 

Reel Cutter. A type of cutting-off table (q.v.) in which the wires are stretched within a large circular frame, the axis of which is slightly above the line of the extruding clay column. This type of cutter can operate on a stiff clay and, if powered and automatic, has a high output.
