Patent DE-3243997-A1 (DE)
Title: Wheel suspension for motor vehicles, especially rear wheel suspension
Inventor: RESS LEO
IPC: B60G9/00
Filed: 1982-11-27
Abstract: The wheel suspension comprises a rigid axle beam, on either end of which a shock absorber or spring strut carrying a wheel carrier is supported. Between these parts a universal joint is inserted which is fixed on the axle beam so that it cannot rotate. The axle beam is pivoted on the vehicle body by means of longitudinal suspension links rigidly fixed to this. In this construction the wheel carriers only have two degrees of freedom lying in vertical planes perpendicular to one another so that, although capable of wobbling, they are supported on the axle beam in such a way that they cannot rotate about a vertical axis. The wheel carriers are thereby held on the axle beam with a fixed toe-in so that only those moments caused by wheel caster acting about the vertical axis act on the axle beam. Moments resulting from longitudinal and lateral guiding forces and acting about the other two axes of rotation of the universal joint are only supported as forces on the axle beam.

Title: Heterogeneous catalyst and method for its preparation
Inventor: MOSKOVITS MARTIN
IPC: B01J37/34
Filed: 1982-12-20
Abstract: Catalysts for accelerating heterogeneous chemical reactions such as hydrogenations, cracking, dehydrogenations and Fischer-Tropsch reactions are prepared by electrolytic deposition of a catalytically active metal such as nickel on an aluminium substrate in such a way, that the metal particles are deposited in microparticulate form to enhance their catalytic activity. The aluminium substrate is prepared by cleaning and anodising it in order to deposit thereon an aluminium surface film having microporosity. The substrate is then dipped into an electrolytic bath of a salt solution of the metal which is to be deposited, and is subjected to AC electrolysis in order to bring about the desired deposition. Prior to use, the catalysts thus prepared should be heated in order to remove absorbed gases from their porous surfaces.

Title: Device for heat transfer
Inventor: RUFF KLEMENS
IPC: F28G9/00
Filed: 1983-03-16
Abstract: Devices for heat transfer which have a multiplicity of heat transfer tubes assembled to form bundles are then subject, in particular, to the risk of clogging due to contaminants when impure waste gases flow through them. The risk is increased when the dirt sticks in the tubes owing to undershooting of the dew point. It is now possible by means of the invention to apply a cleaning fluid 11 partially to the heat transfer tubes 3 without having to take the entire device 2 out of service. Arranged for this purpose above the upper tube plate 5 is a scavenging chamber 12 which can be displaced at intervals or cyclically over 360 DEG , successively supplies the heat transfer tubes 3, which are situated therebelow in each case, with cleaning fluid 11, and partitions off the remaining heat transfer tubes 3. A collecting chamber 33 can be integrated in the collecting funnel 27 in order to collect the cleaning fluid 11. Said chamber can be pressed sealingly against the lower tube plate 6 and can be moved in synchronism with the scavenging chamber 12. <IMAGE>
