Inlet sockets

A possible location for an additional X-cap is directly on the prongs of the inlet socket (at the entrance to the power supply). We remember that in this position any line-to-line capacitor will be exposed to a huge current surge at power-up, and could degrade, if not fail immediately. So if this X-cap position seems to be the last resort, it should at least be made as small as possible (typically 0.047 iF to 0.1 < I ). Or we can try ceramic capacitors in this position (approved ceramic X-caps or Y-caps should be tried here). 

Similarly, the two front-end Y-caps ( C4 in Figure 10-1), or two additional Y-caps, can also be connected directly on to the prongs of the ac inlet socket, rather than on the PCB. This can help a great deal if the wires going from the PCB to the mains inlet socket are themselves picking up stray fields (and are therefore beyond assistance from the main filter stage, which unfortunately lies on the PCB — before the point of noise injection). 

In that case braided wire can also be used. In the past, major power supply manufacturers had their own special custom-made metal brackets to connect the earth prong of the IEC inlet socket to the enclosure. But nowadays, standard IEC 320 inlets with built-in metal brackets are directly available, such as that from Methode Electronics Inc. at www.methode.com.

The swan neck adapter of Fig. II, 56, 12 is useful for distillations as it permits the use of a capillary tube (held in position by a short length of heavy-walled rubber tubing) not sealed to a ground joint. It may also be used for inser tion of a thermometer or a gas-inlet tube in the narrow neck and a reflux condenser into the ground joint this device virtually converts a three-necked into a four-necked flask. Common sizes are cone fil9, 24, 29, or 34 socket 19, 24 or 29. 

Floating covers set up of tarpaulin consist of reinforced tarpaulin like it is used as lorry tilts. The tarpaulin is stretched by an in-drawn ring-shaped PVC tube. It is also working as a float, so it is impossible that manure gets from the border onto the surface of the tarpaulin. Adjusting devices of jet mixers and inlet tubes pass it through conical sockets. 

Multiple socket lids for fitment to the flange flasks (illustrated in Fig. 2.8(c)) are shown in Fig. 2.18(a) and (b). These allow for the introduction of a great variety of standard equipment for stirring, temperature measurement, the inlet of gas, etc. The sockets may be vertical or angled at 5,10 or 15 degrees from the vertical axis. 

Where the addition of solid is required to a reaction mixture, which is being heated under reflux with stirring, either of these devices may be attached to the upper socket of the reflux condenser, which must, of course, be of the Liebig type. In these circumstances a second reflux condenser must be fitted with a guard-tube or with a nitrogen inlet system (cf. Fig. 2.60) to allow for equilibration of pressure within the apparatus. 

The arc lamp C is attached by metal clips to the hollow support tube F which also allows flushing of the lamp area by nitrogen via inlet G and outlet H. The support tube F, the electrical leads to the arc lamp (not shown) and terminals for the cable from the power control unit (also not shown) are all attached to the terminal block J which is fitted with an insulating cover. The terminal block is attached to the inner quartz jacket by means of a rubber sleeve K and two sleeve clips, so that all the live parts are protected. The lamp and inner quartz jacket B can be withdrawn from the 40/38 socket attached to the outer quartz jacket A shown, and the entire unit can be withdrawn from the central socket of the reaction flask.

Pyrohydrolysis.—(a) Consistent analyses were, however, obtained by a modification of the pyrohydrolytic techniques described by Welsh and Parker and by Rushmere and Mason. The apparatus consisted of a silica tube, 40 x 2 cm., a 35/20 B.S. socket at one end, and a B.IO cone at the other to the last a Pyrex condenser was fitted. The steam-preheater and steam-trap, of J in. copper tubing, were linked to the 35/20 B.S. socket by means of a brass ball, machined to fit. The silica tube was heated in an electric furnace, and its temperature was measured with a thermometer. The steam was generated in a three-necked 1-1. flask provided with an air-inlet, an air-steam outlet, and a thermometer. 

The sensor chip was bonded to a socket with inlet and outlet flow channels. The aqueous solution to be measured was pumped through the inlet tubes into the silicon chip cavity coated with a 220 nm thick PECVD silicon nitride film to provide chemical protection. In the present work, three sensor designs have been used ...
