Title: Mixed Raney catalyst for fuel cells - comprising silver-gold-aluminium alloy, avoiding ageing
Inventor: EWE HENNING DIPL PHYS DR RER N
IPC: H01M4/98
Filed: 1973-03-28
Abstract: A mixed catalyst consists of two active metals, silver and gold, for electrochemical cells, esp. fuel cells, contg. 10.65 wt.% Ag (based on the total metal content) and 1-20 wt.% Au (based on the silver content), and balance aluminium. The pref. compsn. is, in wt.% 20 Ag, 1 Au, 79 Al. This catalyst eliminates the ageing which occurs with electrodes contg. Raney silver. A fuel cell was made using the Raney Ag/Au mixed catalyst instead of Raney silver, the electrolyte being 6 m KOH at 60 degrees C, covered with paraffin. The initial electrode potential was 800 mV at a current of 1.9 A, the current density being 150 mA/cm2, and the oxygen press. 18 M/cm2 (1.8 Atm). The current was held constant at 1.9 A. and the change in potential, with time, measured. After 1600 hours, the potential had only dropped to 700 mV, whereas in a similar cell using an electrode contg. Raney silver the potential dropped from 800 mV to 350 mV after the same lapse of time.

Title: Intermittently-operating central-heating boiler - elliptical plate closes chimney when boiler turns off
Inventor: AUGENSTEIN HORST
IPC: F23N1/06
Filed: 1974-12-19
Abstract: Under the central heating's thermostatic control, the boiler is either fully operative or turned right off. Turning off the boiler does not, however, turn off the chimney draught; this continues, encouraged by the warmth of the flue, bringing cold air to cool the boiler and the chimney too. To avoid this waste, an elliptical plate is placed in the flue pipe to close it when the boiler is turned off. The same thermostat signal controls both the boiler and the flue plate; but, for safety's sake, an extra contact is included in the circuit so that a switch-on signal cannot reach the boiler until the chimney is fully open again.
