Title: Diversity-antennenanordnung
Inventor: RADDANT HANS-JOACHIM
IPC: H04B7/08
Filed: 2002-02-21
Abstract: Es wird eine Diversity-Antennenanordnung (100) vorgeschlagen, die eine reduzierte Zahl von Umschaltvorgängen zwischen verschiedenen Antennen bei möglichst geringem Bauteileaufwand ermöglicht und  einen Antennenumschalter (20) zum Umschalten zwischen verschiedenen Antennen (11, 12) umfasst. Die Diversity-Antennenanordnung (100) umfasst weiterhin eine Auswertungsschaltung (5) zur Auswertung der Empfangsqualität eines Signals, das von einem über den Antennenumschalter (20) einer Empfangsvorrichtung (4) zugeführten Empfangssignal (24, 25) mindestens einer der Antennen (11, 12) abgeleitet ist. Die Auswertungsschaltung (5) dient ausserdem zur Ausgabe eines in Abhängigkeit der ermittelten Empfangsqualität gebildeten Auswertungssignals. Weiterhin ist eine Steuervorrichtung (6) vorgesehen, die den Antennenumschalter (20) in Abhängigkeit des Auswertungssignals ansteuert. Eine Bewertungsvorrichtung (1, 2) bewertet das über den Antennenumschalter (20) der Empfangsvorrichtung (4) zugeführte Signal (24; 25) mit einem ersten Koeffizienten bewertet. Es ist mindestens eine weitere Antenne (10) vorgesehen, deren Empfangssignal (22) die Bewertungsvorrichtung (1, 2) mit einem zweiten Koeffizienten bewertet. Eine Summierschaltung (3) addiert die mit den Koeffizienten bewerteten Signale. Eine Regelschaltung (110) bildet die Koeffizienten im Sinne einer Minimierung zeitlicher Schwankungen der Amplitude des Summensignals. Die Auswertungsschaltung (5) wertet die Empfangsqualität des Summensignals aus.

Title: Gearless wheeled gantry crane straight travel system - uses forces between rail and guide rollers to control drive
Inventor: SCHUSTER ALOIS JOHANN
IPC: B66C9/16
Filed: 1973-10-12
Abstract: The system is for use with a portal or gantry crane, where the wheelbase is relatively short in proportion to the span, and two or more pairs of guide rollers are mounted on opposite sides of the rail on the crane frame or on bogie balance members, with the aid of holder members. Measuring units detect loadings on the holder members from the reactive forces exerted by the rail on two guide rollers resulting from the crane initially running crooked, and regulate the crane drive mechanism so as to rectify matters. The rollers are mounted at intervals from each other in the direction of travel and on opposite sides of the rail. On common loading of two diagonally opposite rollers on opposite sides of the rail, two measuring units can be arranged to move an adjustment acting on the drive mechanism.

Title: UV-curable (meth)acrylate esters for use as printing ink binders - from (meth)acrylic acid and triglycidyl (iso)cyanurate
Inventor: TRIEBEL WOLFGANG DIPL CHEM DR
IPC: C09D11/10
Filed: 1974-03-27
Abstract: polyfunctional esters of (meth)acrylic acid are prepd. by (a) reacting 1 mole of triglycidyl cyanurate (I) or triglycidyl isocyanurate (II) with mmoles of acrylic acid and/or methacrylic acid and (3-n) moles of a non-polymerisable fatty acid (n = 2 or 3) at 50-80 degrees C. in the presence of an inert diluent and a radical polymerisation inhibitor, and (b) removing the diluent. The esters are esp. useful as binders for printing inks. The viscosity of the products can be adapted for requirements by controlling the process conditions (reaction temp. and time) and by adjusting the amt. of diluent used; the esters polymerise with only limited crosslinking, thus giving less brittle polymerisation products than usual; fast-curing times can be achieved (e.g. 1-40 sec. with a 180W UV lamp).
