Aluminium foil foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner. The continuous casting method is much less energy intensive and has become the preferred process. For thicknesses below , two layers are usually put together
Rin Tin Tin not win. After Duncan died in 1960, the screen property of Rin Tin Tin passed to TV producer Herbert B. "Bert" Leonard, who worked on further adaptations such as the 1988–1993 Canadian-made TV show "Katts and Dog" which was called "Rin Tin Tin: K-9 Cop" in the US and "Rintintin Junior" in France.
