Angle iron

Fig. 11,10, 3, depicts a housing for the apparatus of Fig. 11,10, 2, a it is easily constructed from lengths of angle iron and asbestos board. If desired, torch bulbs may be fixed in the appropriate holders in the walls, and connected with a dry battery or accumulator in order to provide illumination of the melting point apparatus. The electric bulb immediately behind the apparatus should be connected to an inde pendent micro-switch. Alternatively,...

An extended line, sometimes called a dip leg or dip pipe, reduces the electrical charge that accumulates when liquid is allowed to free fall. When using dip pipes, however, care must be taken to prevent siphoning back when the inlet flow is stopped. A commonly used method is to place a hole in the dip pipe near the top of the vessel. Another technique is to use an angle iron instead of a pipe and to let the liquid flow down the angle iron (see Figure 7-21). These methods are also used when filling drums. 

Apparently a vault had been constructed around the superstructure of the furnace. It was 4.5 x 6 m in cross section and 4 m high. It was constructed of 20-cm-wide flange beams on 0.8 m (front) and 1 m (sides) centers faced on both sides with 10-mm steel plates and filled with dry sand. The explosion displaced the walls about 6 cm. The top of the vault which was supported by a 30-cm beam on top of a 20-cm beam was deflected about 8 cm. Steel doors mounted to slide in angle-iron tracks were blown off. A number of 1.9-cm bolts holding the door tracks were sheared cleanly. The furnace was driven down into the concrete floor and a penetration of some 10 cm was measured. 

The safest arrangement for dealing with the problem of overnight reactions, particularly those carried out on a fairly large scale, is to have available some form of simple shelter constructed of angle iron and heat-resistant sheeting fitted...

The earlier photos show several multistage centrifugal contactors. An operating four-stage 4-cm contactor is shown in Figure 10.10. In this contactor, the motors are side-mounted. The support frame is the L-shaped angle iron to which the motors are mounted. The end of a bank of 2-cm contactors is shown in Figure 10.11. Notice that these motors are face mounted. 

The permeable barrier was composed of a steel frame that was constructed to hold the SMZ and to allow for media replacement. The frame was constructed of 5-cm steel angle iron and 2.5-cm and 7.6-cm square steel tube. The frame had solid floor and end walls (1.3-cm-thick steel plates) to divide it into three distinct cells. Each cell had perforated metal walls (0.16-cm thick perforated steel sheets with 0.64-cm holes covering 50% of the surface area) transverse to the direction of flow. The perforated metal was installed on both the inside and the outside of the steel tube skeleton, resulting in a 7.6-cm-wide annulus between the inner and outer walls of the frame. The entire frame assembly was professionally painted with high-quality, rust-resistant paint. The barrier frame was placed in the pilot-test tank in three sections on top of a 1-m depth of aquifer sand that had been previously added to the tank in lifts. The physical and chemical properties of the sand are described later in this chapter. The three frame sections were bolted together after applying a silicone caulk (Sika-Flex ) for sealing. The end of the barrier in contact with the side of the tank was sealed to the... 

The employees returned on Sunday to complete the job. They decided to strengthen this poorly-constructed box by welding a 2-inch (5 cm) angle iron stiffener around the middle of the ill-designed box. After the angle iron improvement was completed, the mechanic closed the valve and moved away. It was a good thing he did move away rapidly, because the box quickly exploded. 

The middle iron plates e1, e2 etc. act as bipolar electrodes, and have on both sides extended perforated sheets n. The terminal monopolar electrodes have only one sheet n each. The diaphragm frame holds the asbestos cloth. The top edges of the electrodes and diaphragm frames have angle irons a, b, which are riveted and form a flat surface beneath the electrolyte level. This surface iB... 

Angle irons, both on the door panel as well as on the door frame, all around, give the entire door construction more stiffness and precision of measurement. 

Most of the materials that we have discussed—glass, stainless steel, aluminum, brass, plastics—require no protective coating. Parts made of mild steel, welded angle iron, or pl3Twood should be given a coat of paint, which is most conveniently done using du Pont Krylon acrylic aerosol sprays. Clear polymer varnishes and Teflon coatings can also be applied in spray or liquid form. 

Mounted in the tool holder, this follow rest is effective for supporting slender work in a lathe. The rest consists of a square steel arm bent to the shape shown and tapped at the outer end for an adjusting screw. The latter is turned down at the end to fit a hole drilled in the center of a short section of angle iron, which supports the work.

Mechanically, an inverted angle-iron of suitable design in the mud drum will aid in removing unwanted particulates from the boiler. Such a device is shown in Fig. 3. 

According to Kaye 5l currently much in use arc laced concrete walls (Fig. 131) forming a shock wave barrier, but more modern designs are those of suppressive structures. They are made of new suppressive structures of several layers of louvered and perforated plates of angle iron and z bars. This allows controlled release of blast effects from a detonation within the structure. Subsequently a controlled release of blast effects occurs. 

Week of Aug. 31-Sept. 4— DFS feed chute gets jammed with rocket pieces. Site team shuts down DFS to change out warped section of feed chute. Angle irons used to dislodge previous jam get jammed in chute also. 

We have seen how heat transfer and thus dry deposition of SO2 is reduced on large surfaces, due to the buildup of boundary layer thickness (which reduces the local gradients). However, there are economically important structural objects composed of many elements of small dimension which show the opposite effect. These include fence wire and fittings, towers made of structural shapes (pipe, angle iron, etc.), flagpoles, columns and the like. Haynie (11) considered different damage functions for different structural elements such as these, but only from the standpoint of their effect on the potential flow in the atmospheric boundary layer. The influence of shape and size act in addition to these effects, and could also change the velocity coefficients developed by Haynie (11), which were for turbulent flow. Fence wire, for example, as shown below, is more likely to have a laminar boundary layer.
