Punching holes

Newer variations of the normal asphaltic subbase include a permeable version (4) which allows rainwater to trickle through holes punched into the underpad and to drain away through the asphaltic subbase to a pipe grid system under the base (Fig. 4). 

Hardboard is available in either 1/8 or j in. (0.32 or 0.63 cm) thicknesses. It is available as peg board with holes punched in it. A significant but declining use has been in interior paneling and exterior siding, and it competes in many appHcations with thinner OSB and plywood. The U.S. market for hardboard was approximately 669 milHon or 455 X 10 (4.9 biUion ft, 1/8 in. basis) in 1989. 

The notebook contains 114 pages of graph paper in a convenient 8 A X 11, 3-hole-punched format, carbon included. The new edition adds tables and graphs that make it a handy reference as well.

This work was done in collaboration with Professor Hiroshi Yoneyama of Osaka University [124], The procedure used to prepare the LiMu204 tubules is shown schematically in Fig. 21. A commercially available alumina filtration membrane (Anopore, Whatman) was used as the template. Alumina is especially suited for this application because of its high porosity, monodispersity of pore size, and the fact that it can be heated to high temperature without degradation. This membrane contains 200-nm-diameter pores, is 60 p,m thick, and has a porosity of 0.6. A 1.5 cm X 1.5 cm piece of this membrane was mounted on a Pt plate (2 cm X 2 cm) by applying a strip of plastic adhesive tape (also 2 cm X 2 cm NICHIBAN VT-19) across the upper face of the membrane. The Pt plate will serve as the current collector for the LiMn204 battery electrode material. The strip of tape, which will be subsequently removed, had a 1.0 cm circular hole punched in it, which defined the area of the membrane used for the template synthesis of the LiMn204.

Brisance by the Lead Plate Test was detd by Rohrlich and Sauermilch (Ref 11) with caps contg as top charge 0.05, 0.1, 0.2 or 0.3 g trimeric peroxide(compressed to 250 kg/cma), an intermediate charge of 0.3 g PETN(compressed to 250 kg/cma) and a base charge of 0.5 g PETN(compressed to 500 kg/cmJ). The holes punched by these caps were comparable to those produced by No 8 caps... 

Let s take a close look at the use of the term AH. Figure 11.2 shows a bucket with a hole punched in its side. The velocity of the water, as it escapes from the hole is V in the preceding equation. The height of water in the bucket, above the center of the hole, is AH. If we replaced the water in the bucket with gasoline, which has a lower density, the same hole velocity would occur with the same height of fluid.

For many years, nearly all the substrate materials used in the electronics industry were ceramics produced by tape casting (Mistier, 2000). These substrates consist of multiple layers of tape-cast material acting as the insulative carrier, with layers of metal deposited by sputtering, CVD, or evaporation processes. Holes punched into the tapes fill with metal and act as vias or pathways between layers when the tapes are stacked. Stacked layers of tape-cast blanks are laminated together and then sintered to produce a monolithic substrate. This process is detailed in many handbooks on electronics packaging (e g., Harper, 2000). One of the prime benefits is that the layers of the final part can be different different hole patterns, different metallization patterns, even different dimensions on each layer. 

Application to Fabrics with Holes. The specimens with holes punched in them were wet in distilled water, then individually placed on a coarse supporting screen (16/inch mesh) in a Buechner funnel. A vacuum of 15 torr pressure was applied, and 100 ml of slurry made from the papermaking pulp was poured over the specimen. After applying the pulp, the samples were transferred to a larger screen and air dried. The application was repeated without the initial wetting as many times as desired. 

United States Standard Tear-gas Grenade.—The standard lear-pat grenade (CN), M-7, consists of the container, igniting fuse, and filling (see Fig. 11). The container is a tin cylinder 2 in. in diameter and 4 in. high. Two thin disks are crimped and soldered to the wall forming the top and bottom of the container. The top has a f -in. hole punched in its center into which is inserted and soldered an adapter. The latter is internally threaded to take the igniting fuse. Small holes are punched... 

Slow solvent evaporation is a valuable method for producing crystals of high quality it is used primarily for small molecules. The rate of growth is manipulated by adjusting conditions (initial concentration, temperature, evaporation rate) so that crystals are obtained in a few days, not months or minutes. The rate of evaporation can be adjusted by covering the solution with a watch glass or a piece of film (aluminum or Parafilm ) with a number of small holes punched in it. The solution is then left to stand undisturbed.
