gas ballast pumps: Type 2 RVP 20 with a pumping speed of 1.2 m3/h and Type 2 RVP 400 with a pumping speed of 24 ma/h. In spite of their simplicity, both forevacuum pumps are capable of an end pressure of about 1O-3 torr.

Mannheim and DRAIS of MannheimWaldorf exhibited vacuum agitators and kneading machines and drying machines with Leybold sealed piston pumps with pumping speed of 60 and 100 m3/h. Fried Krupp Mass
& Analysentechnik of Bremen (previously ATLAS) showed their mass spectrometer GD 150. This instrument has a measurement range of between
M = 2 and 300 with a resolution ofpM = 120 (signal intensity 10 per cent). The smallest detectable pressure is 1 x 10-l’ torr; total

Gases with mass numbers of between M=4 and M=46 can be used as test gases. Its limit of detection is in the region of 10-l’ torr-litre/sec. An automatic graph evaluator, working on the principle of planimetry, and the integration of graphs and diagrams by scanning light rays, may be specially applied for the quantitative analysis of mass-spectra.

The electron beam welding equipment in particular attracted a lot of interest. This equipment, which was developed in collaboration with the Research Institute, Ardenne, was regularly shown in operation. With an accelerating voltage of 30 kV and beam current of up to 200 mA it can provide the solution to various technical welding problems. Other exhibits were as follows: Freeze-drying equipment TG 15, for the preservation of temperature sensitive materials such as blood plasma, enzymes, antibiotics and albumin specimens, with a charge volume of 15 1 and minimal working temperature of -50°C at 1 X 10m3torr. High vacuum annealing oven WWSO/ 1400 for heat treatment (soldering, annealing, sintering, degassing etc) up to 1400°C under vacuum or inert gas. High vacuum vaporizing equipment B55 with water cooline and heatahle double walled bell-jar and base plate. Maximum power for both resistance heated evaporators is 2 kVA. Water-cooled three-stage oil diffusion pumps from Series ED0 with nominal pumping speeds of 30, 100, 500, 2000, 30,000 and 80,000 l/s. Sputter-ion pumps, Series EGZ, with nominal pumping speeds of 10 and 100 litres/sec. This diode pump is distinguished from other conventional sputter ion pumps in that it incorporates a ring magnet which has the effect of lowering the weight of the pump and the scattering through the pump orifice. The pump housing is particularly outstanding for its modern design which allows for easy assembly. Sorption pump EGS 500, filled with Zeosorb 5A, in a 25 litre tank, pressures of 5 x 10m3torr can be obtained by liquid nitrogen cooling and is particularly suitable as a forepump to sputter-ion pumps. The residual gas analyzer “Inditron” is a partial pressure gauge which operates essentially according to the “Farvitron” principle-and is used in the detection of oscillating ions. The mass spectra are displayed on the projection screen of the cathode ray oscillograph with a resolution of AM M =20 and measured in three separate
