During this visit, measures were taken to implement the decisions adopted by executive council at its 13th meeting; the preparation of the next meeting was undertaken. 3. The Israeli Society for Vacuum Technology is integrated in the Union It was mentioned in the News Bulletin No 13 (June 1968) that Mr A Roth, chief engineer of the Vacuum Technology Department of the Israeli Atomic Energy Commission, had taken steps to group all the vacuum specialists in his country. A new Vacuum Group has been successfully formed with Mr Roth as President. This group which is called "The Israeli Society for Vacuum Technology" has submitted application for membership to the Union. According to the statutes, the executive council of the Union has now voted for the provisional admission of the Israeli Society. The Union welcomes its accession as the 16th national committee. The address is as follows: The Israeli Society for Vacuum Technology c/o A Roth Soreq Nuclear Research Centre Yavne, Israel.
4. Publication of the "Measurement of the performance characteristics of vacuum pumps" (First part) P N E U R O P (European Committee of Manufacturers of Compressed Air Equipment) lists manufacturers of this equipment in 12 European countries. The following countries are members 248
of this Committee: Austria, Belgium, Denmark, France, Germany (Federal Republic), Great Britain, Italy, Liechtenstein, Luxembourg, Netherlands, Sweden, Switzerland. A few years ago, P N E U R O P created a sub-committee No 5, whose task was to determine the measurements of the performance characteristics of vacuum pumps. The secretariat was administrated by the "Fachgemeinschaft Pumpen und Verdichten im Verein Deutscher Maschinenbau-Anstalten e.V. (VDMA)". The aim of these measurements is to determine the efficiency curves of a vacuum pump and to remove misunderstandings between manufacturers and users. The first part of this work has now been published in the three official languages of PNEUROP, German, English and French. The brochure (14 pages, 9 pictures) costs D M 1.45 and is available from: Maschinenbau-Verlag G m b H 6 Frankfurt/Main Niederrad 1, Pf. 109 Bundesrepublik Deutschland.

5.1. Short summary of the seminar organized by the Technical Academy of Esslingen "Aufdampfen in der optischen Industrie" (20 and 21 June, 1968). The seminar on "Evaporation techniques in the optical industry" organized on 20 and 21 June, 1968 under the chairmanship of Dr Wutz (Hanau) was very successful. Among the 76 participants, 19, ie nearly 25~o came from various European countries (Austria, Netherlands, Switzerland, Yugoslavia). The majority of the participants were chemists, engineers and physicists. An important number were opticians, technicians and skilled mechanical staff. Emphasis was laid on the debates which were so animated that on several occasions the allocated time was overrun. The lecturers were: Dr H Anders (Oberkochen), Dr W D Dachselt (Hanau), Dr K Deutscher (Wetzlar), Dr D Hacman (Balzers, Liechtenstein), Dr G Kienel (Hanau), Prof D r H Mayer (Clausthal), Dr H K Pulker (Balzers, Liechtenstein), Dr W Reichelt (Hanau), Dr K Schmieder (Clausthal). An exhaustive survey was made of the physical patterns and various techniques (principles of vacuum evaporation techniques, evaporators, condensation patterns, optical properties of thin films and measurement of thin film thickness). The practical applications and new theoretical knowledge were also studied. Advice and proposals were made to the practitioners.
5.2. Short summary of the seminar held by the Technical Academy Bergisch-Land (Wuppertal): "Metallisieren yon Kunstoffoberfliichen mit besonderer Beriicksichtigung der Aufdampftechnik" (November 5-7, 1968) In cooperation with the "Deutsche Arbeitsgemeinschaft Vakuum" (DAGV), the Technical Academy Bergisch-Land, Wuppertal, a seminar organized from November 5 to 7, 1968, on "Metallization of synthetic materials surface with special emphasis on vacuum coating", under the chairmanship of Dr Wackernagel (Ntirnberg).
News from the vacuum societies
After the introductory speech on the possible metallization of synthetic materials and on the characteristics shown by more important techniques, processing technology, adherence problems, quality control, efficiency questions and future possibilities were discussed. The lecturers were: Dipl Phys Kerner (Stuttgart), Dr Kienel (Hanau), Dr Traub (Stuttgart), Ing Walter (KiSIn), Dr Wiebusch (Ludwigshafen), and Dr Ing Woldt (Berlin). Among the 43 participants, 70 % were engineers, chemists and physicists. The great success of this seminar, which had been carefully prepared, was proved by the animated debates. The proposals made by the listeners will be taken into account for future meetings. The following meetings are planned for 1969: Seminar: "Messger~.te und Messverfahren in der VakuumTechnik" (May 22 and 23, 1969) (Measuring equipments and processes in vacuum technique). Seminar: "Werkstoffe und Werkstoffeverbindungen in der Vakuum-Technik" (November 27 and 28, 1969) (Materials and assembling processes in vacuum technique). 5.3.
