Sep 01 1996 I used my trusty glass cutter whose cutting wheel is supplied with cutting oila mixture of 3 in 1 oil and turps. if you dont have such a beast just dip your cutter in white spirit. I found it impossible to run a continuous cut all around the neck but used a series of small say one inch scores.on no account double up over a score do it

Sep 01 2020 This study investigates the recycling of mobile printed circuit boards through physical treatment followed by hydrometallurgical processing. Copper dissolution of the feed and processed fractions using different lixiviants were studied. Fluidization provided an effective separation of metallic values and 88 carbon removal were observed.
The Figure 18 circuit is designed around a CMOS 7555 ‘timer’ IC that is used in the astable mode and typically consumes an unloaded operating current of 75µA at 6V. In this mode C1 alternately charges up via R1 R2 and discharges via R2 only thus generating a highly asymmetrical output waveform on pin 3 which pulls the LED on via current
