Title: Automatic frequency controlled oscillator circuits
IPC: H03L7/181
Filed: 1972-12-20
Abstract: 1409670 Automatic frequency control SIEMENS AG 20 Dec 1972 [22 Dec 1971] 58835/72 Heading H3A In an a.f.c. system for an oscillator 1 comprising a forward/backward counter 4 which counts output oscillation from the oscillator 1 and a comparator 5 which compares the count with a desired value, the actual value in the counter 4 is adjusted to the desired value by the additional input of pulses from an auxiliary source f h  which step forward or backward the counter 4, and a second forward/backward counter 6, and a D/A converter 7 converts the output from the counter 6 into a control voltage for oscillator 1. Pulses derived from oscillator 1 are fed into counter 4 via gate 3 for a period determined by the duration of pulse P. If at the end of this period the count of counter 4 is too low, comparator 5 emits an output on line K 1  to open gate 8 feeding pulses from source f h  to the forward stepping inputs of counters 4 and 6 until equality is reached. Similarly if at the end the count is too high, an output on line K 2  open gate 9 feeding pulses from source f h  to the backward stepping inputs. A signal indicative of the desired value count is also applied to a second D/A converter 15 to provide coarse frequency control. The frequency f h  may be derived from the oscillator output signal f x  by a frequency divider. In a modification, Fig. 2 (not shown) the oscillator output is counted in a further counter (11), and the count then transferred to counter 4.

Title: Atomizer nozzles
IPC: F23D11/24
Filed: 1978-07-21
Abstract: In the process for atomizing a stream of liquid by means of an atomizer nozzle, the liquid is sub-divided into two partial streams upstream of the atomizer nozzle. One of these partial streams is passed through an axial bore 5 in the nozzle body 1 and flows through a cylindrical swirl chamber 6 in the body. The other partial stream is superimposed on the first partial stream at right angles thereto in the swirl chamber 6 from an aperture 12 opening tangentially into the swirl chamber. The resulting combined liquid jet then flows through a cylindrical dwell chamber 7 and leaves through an axial outlet nozzle 8 as a solid cone spray jet. The spray angle can be continuously adjusted between 0 DEG  and 70 DEG  by adjustment of the quantitative proportions of the two partial streams. <IMAGE>

Title: Damper control device in a unit for evacuation of welding fumes
IPC: B08B15/00
Filed: 1978-08-30
Abstract: A device is provided for automatically controlling the damper in a unit for evacuation of gases and other particles, which may arise at a welding workplace. A control means is provided which is actuated by a scanning means, which in response to whether or not welding is going on causes the control means to open and, respectively, close the damper. Hereby the unnecessary evacuation of heated air from a workroom is avoided and thereby the heating costs for said room are reduced. As illustrated the gases are exhausted through a hose 4. The scanning means may be a photoelectric cell (18), Figure 6 (not shown), in a pipe 19. The cell scans the existence and absence of an electric welding arc. Alternatively, the scanning means may be a device capable of scanning the existence and absence of welding current in the welding cable and accordingly controlling a magnet (14), Figure 7 not shown, which controls the damper (6). <IMAGE>
