Abstract: 1. Fitting, especially for a continuous flow water heater. 2.1. The submitted invention takes as its basis the problem of developing a fitting of the named type by which the formation of calcareous deposits on the rod protruding from the water control housing is lessened and the influence of such calcareous deposits on the controller action is completely eliminated. 2.2. The problem is solved in that within water control housing (2), the control motion of membrane (24) is transmitted to a lever (3) whose centre of rotation forms a shaft (4), rigidly connected to this lever (3) and whose pivot is sealed, leading to the exterior of water control housing (2). At the same time, shaft (4) is also the centre of rotation for a second lever (5) which is likewise rigidly connected to it. Thus the stroke motion of the first lever (3) is transmitted to the exterior via shaft (4) as a rotary motion and subsequently the rotary motion of shaft (4) is re-converted, by means of second lever (5), into a stroke motion to control the gas outlet. 2.3 The fitting serves to control gas flow depending on water flow especially for continuous flow water heaters. 3. Fig. 1.

Abstract: A coater head (22) has a housing (23) which defines a coating pond (28) supplied with coating under pressure. A plurality of bars (21) extend within the coating pond (28) in the cross-machine direction, and are spaced parallel to one another in the machine direction. A paper web (36) is engaged against a backing roll (24), and travels through the coating pond (28) past a metering blade (30) which applies coating from the pond to the web. The bars (21) induce a turbulent flow which shears bubbles of air entrained in the coating pond, thereby reducing the bubble diameters and air-induced imperfections in the coating. Greater machine speed, which tends to entrain more air, induces greater shear at the bars which causes bubble size to be more greatly reduced.

Abstract: A fire-resistant facade or glass roof has a supporting structure consisting of post and beam sections in which the post and beam sections define frame fields provided with a fire-resistant glazing. The beam and post sections (21) should be made of aluminum and form closed structural units which can be jointly manufactured for use in fire-resistant constructions. The beam and post sections each have a core section (22) which absorbs the static loads and which is surrounded in its outer wall area by a U-shaped hollow chamber for accommodating molded substances (36, 36.1) consisting of a heat-absorbing, hydrophilic adsorbent having a high proportion of water. Connecting webs are provided between the outer wall of the U-shaped hollow chamber and the core section (22) which ensure a low heat flow from the outer wall of the hollow chamber to the core section. As a result, crystal water is released when the control temperature of the hydrophilic adsorbent is attained and by means of which the metal construction is cooled.

Abstract: An automatic gain control circuit of an amplifier 1 having  a  gain  control  function  is  provided  with  a signal-to-noise   detection  circuit   2   which  detects   a signal-to-noise ratio of an output signal and an AGC setting circuit 3 which sets the gain of the amplifier 1.   The AGC setting circuit 3 determines the AGC gain according to the level of an input signal and the signal-to-noise ratio detected by the signal-to-noise ratio detection circuit 2.  In a region where there is a large AGC gain and where the signal-to-noise ratio is reduced by the AGC circuit, the level of an output signal is increased so as to render the signal-to-noise ratio of the output signal constant.  Even if an input electric field is reduced by a fading phenomenon and if there is an increase in  the  AGC  gain,  there  is  prevented  a  decrease  in  the signal-to-noise ratio due to an increase in the noise floor stemming  from the  AGC circuit  itself,  thereby preventing deterioration of the receiving sensitivity of the automatic gain control circuit.
