Title: Increasing rate of heterogeneous chemical reactions - by very rapidly passing a liquid or gaseous reactant over a solid reactant
Inventor: KATTANEK SIEGFRIED PROF DR ING
IPC: C01G7/00
Filed: 1974-03-20
Abstract: Reaction rate between a solid reactant and a fluid (liquid or gaseous) reactant is greatly increased (in some cases by several orders of magnitude) by passing the stream of the fluid reactant over the solid reactant at a great speed so that the current is strongly turbulent and the laminar flow layer at the phase boundary is very thin. This method can be applied to a great variety of very slow reactions; it is esp. suitable for the prodn. of AuCl3 from the elements. The removal of the reaction product is carried out mostly by correction (as the laminar flow layer through which the product must diffuse is very thin) so that the system is always far from the equilibrium and the reaction rate is high. If the reaction product is unstable, it can be quickly conveyed to a cooling zone and rapidly cooled. Thus a high-purity product can be obtained in high yields.
Patent DE-2418621-A1 (DE)
Title: Anti-squeezing train brake - with plastics resonance damping strips applied radially to wheel disc
Inventor: KUREK ERNST GUENTHER
IPC: B60B17/00
Filed: 1974-04-18
Abstract: The train wheel disc is provided with a number of radial metal strips which are fitted to the discs by means of a damping layer of adhesive. In the centre of the disc the strips are linked by a ring about the hub. The strips divide the disc area up into segments, which may be of unequal size. This eliminates the resonance effect when the brakes are applied. The coefficient of friction of the metal brake blocks on the train wheel increases suddenly as the wheel is about to stop and sets up a resonant squeak as the train stops. The strips provide a simple, economic remedy for this by altering the resonant frequency outside the audible range.

Patent DE-2423918-A1 (DE)
Title: Mixing valve outlet with thermometer - is used for regulating water temperature without thermostat
Inventor: TILSE WILHELM ING GRAD
IPC: E03C1/04
Filed: 1974-05-16
Abstract: The mixing valve uses a thermometer for direct indication of the water outlet temp. This indication is used for manual adjustment of the water temp. This method is cheaper than the use of thermostats. The thermometer eliminates trial setting of the water temp. and the thermometer is especially useful for manually held shower heads. The thermometer 15 with expanding liquid and divided scale is fitted into a mixing valve 8. The lower part of the liquid column projects into the water stream in the valve and hence the water temp. is read directly. In another version the thermometer can give a reading by an indicator with scale where colours represent temp., for example blue for cold, green for body heat and red for hot.
