Patent DE-2721232-A1 (DE)
Inventor: STAMM ROBERT
IPC: G01N33/28
Filed: 1977-05-11
Abstract: The invention relates to a method which makes it possible to determine the boiling point of liquids. Moreover, the invention ensures simple handling of the instrument arrangement. The object of the invention is to provide a method for determining the boiling point of a liquid with an instrument that is easy to handle; in particular, it is to be used for determining the boiling point of the brake fluid of motor vehicles. The liquid is introduced into a small test chamber (11) by means of a pump line (10) and is heated to its boiling point. As soon as the boiling point is reached, the liquid is ejected from the test chamber owing to the generation of vapour. At that point the temperature is measured by means of a thermoelement (14) and is recorded as the boiling point on a display device. <IMAGE>

Title: Ionisation treatment of plastic film surface - where screen of equal polarity and potential reflects additional ions through window
Inventor: BATYREV RUSLAN IVANOVITSCH
IPC: H01T19/00
Filed: 1977-06-02
Abstract: Wire ioniser electrically charges a plastic film by operating as a discharge system connected to a high voltage and enclosed in an insulating housing; a window on the film side of the housing permits the ion stream to emerge there. A conducting screen is located on the side opposite to the window and is connected to the high voltage source so as to produce a field on the screen surface of the same polarity as that of the main discharge and of a potential which is no lower. Provides high intensity of ion stream on to fil, and minimal energy loss.
