Patent DE-3839973-C1 (DE)
Title: Mounting for a vibration generator
IPC: G05D19/00
Filed: 1988-11-26
Granted: 1990-07-05
Abstract: The invention relates to an elastically flexible mounting for a vibration generator which has a drive member excitable to longitudinal vibrations. A leaf spring elastically flexible in the direction of longitudinal vibration serves for the mounting. It is clamped at its free end in a bend-resistant manner relative to the pivotable mounting of the vibration generator by means of a holding fork and at the other end in a bend-resistant and stationary manner. By means of this mounting, essentially only movements along the axis of the longitudinal vibration are possible for the drive member of the vibration generator. Vibrations of other degrees of freedom are therefore suppressed and can no longer be coupled to the longitudinal vibrations and produce additional vibrations.
Patent DE-3916855-C1 (DE)
IPC: H03H7/46
Filed: 1989-05-24
Granted: 1990-05-10
Abstract: The present invention relates to branching directional couplers with a voltage and a current transformer and an internal terminating resistance, in which the junction of the secondary windings of the two transformers forms the branch and the internal terminating resistance is inserted between the secondary winding of the voltage transformer and earth. To achieve branch attenuations of >/= 16 dB in such a branching directional coupler, with little circuit complexity over a wide band up to 1.75 GHz with little transmission loss, a high degree of decoupling and good matching of all connections, an ohmic resistance connected in parallel with the secondary winding of the current transformer and connected to the latter with low inductance is provided which, together with the transformation ratios of the two transformers, is selected in such a manner that the nominal values for the branch attenuation and impedance are obtained as accurately as possible at the branch connection. By inserting a further ohmic resistance between the junction of the secondary windings of the two transformers and the branch connection, a further degree of freedom has been advantageously achieved for the choice of resistances and transformation ratios. <IMAGE>

Patent DE-4034353-C1 (DE)
IPC: C25B1/00
Filed: 1990-10-29
Granted: 1991-12-19
Abstract: A method is disclosed for the preparation of finely divided, electrically conductive tin(IV) oxide. In a first step tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds are obtained by electrolysis, in which the anode consists of tin or a tin alloy which contains a doping metal, and the cathode consists of a metal or graphite. The two electrodes are separated by a diaphragm or an organic membrane which is permeable to hydrogen ions and oxalic acid solution is used as electrolyte. Tin(IV) oxide is prepared in the second step by calcining the oxalates obtained from the solution of tin(IV) oxalate and/or oxalates of polymeric tin(IV) compounds, to which known doping agents have been added in conventional amounts.

Title: Valve fitting
Inventor: KOERTGE RANDOLF
IPC: B62D5/06
Filed: 1994-07-15
Granted: 1995-11-23
Abstract: The valve device has a flow control valve with sprung valve piston and a supply flow throttle. This throttle is composed of two part supply flow throttles (130,132) operating independently of each other. The first one (130) is dependent on the path, and the second one (132) on the static pressure. The second one can be opened by a pressure difference between the working pressure of the hydraulic supply device and an adjustable pressure on the valve piston (86), depending on the intake of the supply flow. The second part flow throttle is formed from a sprung annular piston.

Granted: 1996-03-14
Abstract: A device for carrying out spectroscopic measurements based on the principle of interferometry has a matrix of photodetectors. A plurality of interferometers consist each of two partially transparent parallel mirrors arranged in a rectangular matrix so that the mirrors of as many interferometers as possible be mutually separated by different distances. As many different reflection phase positions as possible are thus obtained in the matrix for each measured wavelength. The different distances are distributed as uniformly as possible in a range between the smallest and largest distance. The matrix (9) of photodetectors is arranged behind the interferometers so that at least one photodetector be associated to each interferometer to receive the light (8a) to be measured that perpendicularly hits the interferometers. A device for converting the output signals of the matrix (9) of photodetectors is provided to represent the spectrum.
