Lead strip

Place the lead strip into test tube 1 and add 10 mF of 0.2M copper(II) sulfate solution. 

Fig. 7 indicates the connections of the chemical condenser for a D.C. circuit. A lead strip is used for the cathode. Fig. 8 shows the connections of a B eliminator filter circuit and Fig. 9 the connections for forming the plates. 

A copper sheet (99.999 % purity, 8x10 mm, thickness 0.2 mm), a nickel sheet (99.99 % purity, 10x12 mm, thickness 0.2 mm) and an iron sheet (99.99 % purity, 10X12 mm, thickness 0.1 mm) attached with a lead strip of the same metal were used as electrodes in infrared measurements. The electrodes were polished to a...

Material Beaker, battery (4.5 V), voltmeter (multimeter), electric motor, cable and alligator clips two lead strips, sulfuric acid solution (20%). 

Procedure Fill a beaker two-thirds with sulfuric acid. Place lead strips at opposite ends and hold in place with alligator clips. Electrolyze the sulfuric acid with a battery of 4.5 V supply. Wait for about one minute, remove the battery. Measure the voltage using a voltmeter, then connect with an electric motor. 

Observation While the electrolysis is running, a gas develops on both sides of the lead plates, thereby turning one of the lead strips dark brown. After this, a voltage of approximately 2 V can be measured, the electric motor works for a short while and then stops. 

The oldest and simplest representative is the tank crystallizer. It consists of an open tank, either rectangular or circular in section, exposed to the atmosphere, which provides the necessary cooling. Frequently, ropes, rods, or lead strips are suspended in the bath to provide a base... 

A low vertical cylinder closed off with a rubber stopper serves as the electrolysis vessel and contains the sulfate solution. The anode is a piece of Pt sheet immersed in a clay cell filled with 20% H3SO4. The cell is partially immersed in the Ti (TV) sulfate solution and is surrounded by four amalgamated lead strips, also immersed in the solution. The stopper on the outer electrolysis vessel has holes for the clay cell and for the inlet and outlet gas tubes. The electrolysis is carried out in a constant stream of COg and with efficient water cooling. The current density is 0.06 amp./cm. at 24 v. for the first six hours, then 0.33 amp./cm. at the same voltage for an additional six hours. This reduces all the Ti (IV) sulfate to Ti (III) sulfate the latter precipitates as an H3804-containing hydrate (fine, pale light violet crystals). 

Some large rooms convert to several smaller rooms with folding partitions. Some partitions are plastic. By itself, the plastic partitions do little to stop sound transmission. Most manufacturers incorporate lead strips into the sections that fold. The goal is to add mass to the partitions to reduce the amplitude of panel vibration and reduce sound transmission. Companies selling partitioning panels provide sound attenuation data for their products. 

Two 45° pads placed against the child s hack and tummy, held in position hy placing sandhags against the pads helps prevent the child rocking . A lead strip placed close to the child s hack helps prevent scatter radiation and improve the image.

After VF induction the asynchronous pacing spikes can be seen marching through the surface lead strip. The pacing spikes do not have any effect on the detection of VF as can be seen by noting the absence of undersensing on the marker channels. 

In the strip expansion process, a cast or wrought lead strip is pierced, stretched above and below the strip plane, and then pulled or expanded to form a grid with a diamond... 

Another method of grid manufacture is via mechanical treatment of a strip or slab of lead alloy. The traditional procedures (Plant6-type plate) have been either to cut grooves into a thick lead plate, thereby increasing its surface area, or to crimp and roll up lead strips into rosettes which are inserted into round holes in a cast plate. The resultant plates are formed electrolytically into positives in the classic Plante and Manchester designs (Fig. 23.13). 

A plot of Pb2+ concentration vs. the anodic stripping current (not shown) was linear and demonstrated the applicability of the BDD electrode in the presence of microwave radiation. It was also apparent that the current response for the lead stripping process was enhanced by application of microwave radiation.
