Title: Silane prodn. by reacting oleic ester with hydrogen silane - the ester contg. a specified amt. of polyunsaturated cpds.
Inventor: HEMPEL HANS-ULRICH DIPL CHEM D
IPC: C07F7/12
Filed: 1978-08-17
Abstract: A silane is prepd. by reacting a commercial oleic acid esher with a hydrogen silane in the presence of a catalyst at >50 degrees C. The oleic esher must contain >4 wt. % of polyunsaturated tpds; if the commercial esher contains >4 wt. % polyunsaturated tpds. this proportion is reduced in an initial step. The silanes are used as hardeners in binders based on alkali metal silicones and as additives to antiseptic agents plasticisers and adhesives. When the oleic esher contains less than 4 wt.% polyursaturates high yields are obtd. The proportion of polyursaturates can be reduced by diminising them, e.g. using fuller's earth or an ion exchange resin, or by partial (5-25%) hydrogenation. The hydrogen silane, e.g. HSiCl3 is pref. reacted with the oleic esher in the presence of an organic peroxide.

Title: Absolute rotation measurement using sagnac effect - with mono chromatic light beam split into parts passed to detector in cyclical time sequence after modulation
Inventor: RUSSER PETER DR TECHN
IPC: G01C19/72
Filed: 1979-10-13
Abstract: Absolute rotations are measured using the Sagnac effect by passing parts of a monochromatic beam in opposite directions around a light path and recombining them before passing the recombined beam to a photodetector. The absolute rotations of bodies which cannot be classed as rigid are measured with great accuracy. The monochromatic beam is divided into an equal number of partial beams greater than 2. One pair of beams is associated in a common light path. The remaining beams traverse different length paths selected so that they are subjected to modulation by orthogonal signals in the time or frequency domain. Each partial beam is passed to the detector in a cyclical time sequence over which the detector output is evaluated.

Title: High resolution ink jet printer - has jet electrode covered with ink and has focusing electrode behind paper
Inventor: EBI YUTAKA
IPC: G06K15/10
Filed: 1980-05-19
Abstract: The high resolution ink jet printer has the ink container (13)-with an exit hole (17) shaped about a needle electrode (18). The end of the electrode is slightly proud of the hole and is covered with ink through capillary action. A signal applied between the needle electrode and an electrode behind the writing paper (21) provides a fine charge of ink.
