Use of a Bent Blowpipe and Double Tipping Device For getting at tubes placed awkwardly in complicated apparatus a bent tubular blowpipe is very convenient. A useful design is shown in Figure 83,1. 

In the DC circuit, the rotating consumable rod serves as an anode and the transfer arc plasma torch or a cooled tungsten tipped device as the permanent stationary cathode. As the anode is consumed, it is moved into the spray chamber. The chamber diameter may be as large as 2440 mm. 

Compound (1) was prepared conventionally from 4-chlorobenzoyl fluoride and SbF5 and dissolved in EtN02. The solution was distributed into phials by the usual tipping device [4] the content of the phials was obtained by the mid-point method [4, 5], and the initiator concentration was determined as described [2],... 

Styrene [16] and methylene dichloride [17, 18] were purified and dosed under high vacuum solutions of perchloric acid in methylene dichloride were prepared by standard techniques [19]. The styrene and the solutions of perchloric acid in methylene dichloride were then transferred into phials with a tipping device [19, 20]. 

A series of experiments were run to find the probable cause of these explosive events. A 20-liter bucket was placed on the ground and a second bucket placed on a stand above it with a remotely actuated tipping device. In alternate experiments, water was poured on LNG and LNG on water. Foamed ice was formed, but no explosions occurred. The tests were extended by adding either additional LNG or water after the initial mixing of LNG and water had taken place. The further addition of LNG had no effect. However, when water was added to an already mixed quantity of LNG and water, an explosive event occurred which threw the contents of the bucket upward about 5 m.

The following points for designing and manipulating a tipping device are worth noting ... 

Fig. 3.7. Tipping device arranged for sublimation. The solid is introduced into A through E which is then sealed off. The assembly is evacuated and sealed off at D. The solid in A is then warmed gently so that it sublimes beyond C, and by cooling the flask B and by dislodging any crystals formed in the parts above it, most of the solid can be collected in B. After sealing off at C the solid can be distributed into the phials P by pouring, if it is a free running powder, and/or by sublimation.

A tipping device can also be used to follow the course of a reaction, if the reaction mixture is distributed into the phials which are then sealed off and subsequently broken and the contents analysed at intervals (Jones and Plesch, 1979 and Section 5.3.4). 

One advantage of this method compared with a tipping device and mid-... 

It is obvious that this technique is less rigorous than those described earlier and that it could have been made more efficient by the use of a tipping device. Nonetheless, it seems to have been adequate for the intended work. 

Figure 27.5 I-V characteristics of a Cu/Cu(TCNQ)/Au-tip device with two distinct stable conducting states.

The Cu/Cu(TCNQ)/Pt device showed similar I-V characteristics as the Cu/Cu(TCNQ)/Au-tip device (Figure 27.7). In contrast to aCu/Cu(TCNQ)/Au-tip device the ratio between the low and high resistive state is smaller and the threshold voltage is not so sharp. The Pt tip was replaced by W, Mo, Cu, Al, and In tips and the I-V characteristics were recorded. Cu, Al, In, and Zr showed similar behaviour as Cu/Cu(TCNQ)/Al203/Au devices. These devices showed an inverse I-V characteristic as devices with Pt or Au tips. In Figure... 

The fabrication procedure for the two-tip device is basically the same as the single electrospray device. First, the two independent microchannels were hot embossed onto one cyclo-olefin polymer chip, and the two sample reservoir holes were drilled onto this cyclo-olefin chip at the end of the microchannels. Then, a gold electrode with a width of 500 pm was fabricated onto another cyclo-olefin chip. A hole for gold electrode access was drilled through the other... 

In-plane emitter tips in which the tips are embedded at the end of the microchannel at the edge of the chip devices have been heralded mainly by the recent advances in microfabrication technology by which low-cost disposable chips are now close to reality. The smaller dimensions of these emitter tip devices were observed... 

Finally, wheelchair modifications include items such as automatic wheelchair locks, laptop safety cushions, seat belts, anti-tipping devices, transfer devices, frame modifications, and wheelchair monitors.
