Abstract: Abstract This invention relates to a catalyst and a method for producing said catalyst. At lest 60 per cent by weight of the catalyst consists of copper oxide, aluminium oxide -spinel and 60-lO0 per cent of the copper present is bound to aluminium oxide as copper oxide, aluminium oxide -spinel, where the atomic ratio Cu:A1 = 0.25 - O.50. The catalyst itself contains 1-20 per cent by weight of zinc oxide which is present in the pores of the spinel. Further amounts of zinc oxide may be admixed mechanically or be present as a coating on the catalyst. The catalyst is especially well suited for conversion of carbon monoxide with steam. The catalyst is produced by precipitation of copper- and aluminium salts at ph = 6.0 - 6.5 during addition of an ammonium or alkali carbonate solution. After filtration and drying, the product is calcined at 750 - 850°C until it is obtained 60-100 per cent spinel structure. Zinc salt is introduced in the pores of the spinel, and the product thereby formed is heated up to at least the decomposing temperature for the zinc salt which is then converted to zinc oxide. Possible addition of zinc oxide in addition to that introduced to the pores of the spinel may be admixed mechanically.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an electric steam iron having a metallic sole-plate, a boss and a heating element, cast in the boss.  There is a main injection device connected to a water re-servoir for injecting water into a vaporization chamber adjacent to the boss, and an auxiliary injection device for injecting a supplementary amount of water for obtaining an instantaneous sur-plus of steam.  The auxiliary injection device empties into the vaporization chamber at a point situated on the boss just above the heating element cast in the boss.  The metal of the boss in the area around such point is thin so that the heating element cast in the boss is close thereto.  The instantaneous surplus of steam is useful for special kinds of ironing work.  This inven-tion has advantages over known devices which have baffled com-partments which are prone to scale deposits.

Abstract: Digitally Driven Combination Coil for Electrodynamic Acoustic Transducers Abstract An electrodynamic acoustic transducer (54) having two voice coils (50, 52), the coils being addressed by amplified digital signals.  The system (12, 60, 54) utilizes a preamplified analog input signal (10) which is supplied to a bifurcated network, one such signal being processed by an inverter (18).  The analog signals (42, 44) are compared with triangular waves (38, 401 to effect switched signals (46, 48) that are pulse width modulated signals.  The signals (46, 48) are then amplified through impedances (76, 78) and high speed, high current semicon-ductor switch means (80, 82) so that the amplified digi-tal signals serve as driver means communicated to the separately addressable coils (50, 52).  There is a dynamic balance achieved by separate energization of the coils (50, 52) whereby the diaphragm (97) is positively located in both axial driving directions and is disposed in equilibrium positions by the energization and balanc-ing of the respective coils (50, 52).  As a result, the dynamic range, clarity, cleaness, and response time is substantially improved.  An important aspect of this invention is the direct addressing of two distinct coils (50, 52) by amplified pulse trains which are of digital characteristic.  The speaker (54) does not require mech-anical restoring means but instead the suspension of the diaphragm (97) has a high compliance and serves only to maintain concentric relationship of the voice coils (50, 52) with the gap (92).
