Title: Method for atomising liquids in a gaseous medium and device for carrying out the method
Inventor: BAZAROV VLADIMIR GEORGIEVIC
IPC: B05B3/10
Filed: 1981-01-30
Abstract: To intensify the atomisation of liquids in a gaseous medium with simultaneous reduction of the energy consumption, a gas stream is formed in which accoustic vibrations are caused. A torque is imparted to the liquid to be atomised. It is then introduced into the gas stream coaxially to the gas stream forming an annular liquid mist. The liquid mist is atomised by the vibrating gas stream forming a gas/liquid mixture. In the gas/liquid mixture formation zone, a system of spiral vortex streets is generated of which each contains vortexes in pairs. This is achieved by a housing (1) having a pipe attachment (9) for forming a gas stream, a liquid atomiser, which is arranged coaxially in the pipe attachment (9) and is constructed in the form of a rotating cup (8), which together with the housing (1) and the pipe attachment (9) forms a cavity (10) for the gas passage. On the outside of the atomiser cup (8) and on the inside of the pipe attachment (9) are formed contacting series of projections (13 and 14), which form channels having varying cross section, which is dependent on the opposing arrangement of the projections (14 and 13) of the pipe attachment (9) and the cup (8) on rotation of the latter.   <IMAGE>

Patent DE-3203549-A1 (DE)
Title: Fully electronic combined alarm system
Inventor: GENGENBACH WERNER
IPC: G08B13/00
Filed: 1982-02-03
Abstract: A fully electronic combined alarm system for monitoring open space (fields) or closed rooms, with exchangeable camera, in which a further alarm signalling device can be connected. After triggering the arming element (SE), the monitoring electronics (1st module) switches on the alarm current. This operates the pulse transmitter (2nd module) via connection F to G. The individual current pulses alternately cause the solenoid (EM) to pull in and drop off which operates the camera release. First, the number of pulses after which the total system is to switch itself off is set on the second module. After this number of pulses has been reached, the entire system switches itself off via connections G and F. To provide the possibility for remote alarm signalling, the radio transmitter (FS) with its own power supply is connected to connection E, which transmitter is switched on in the case of an alarm. The radio receiver (FE) will switch on the self-latching relay for switching on the alarm signalling device (Si). The possibility for changing cameras makes it possible to use the device under different operational conditions. The radio alarm signalling facility which can be connected enables immediate measures to be taken for apprehending the intruder. <IMAGE>

Filed: 1982-02-19
Abstract: A cine projector is proposed which has at least one resilient compensating element between the take-up sprogget and film winding spool for the purpose of compensating for uneven film traction proceeding from the film winding spool. Apart from a compensating element (4, 10, 15) suitable for normal film traction fluctuations, provision is made for a further compensating element (2, 18, 19) which is under the influence of a threshold value spring (13) which responds abruptly after overshooting a film traction of a predetermined order of magnitude. Upon overshooting of the critical film traction value, the threshold value spring tilts suddenly upwards, the film travel being shortened abruptly by a predetermined value with the result that the film traction is simultaneously reduced to non-critical values. <IMAGE>

Title: Dynamic synchronous binary counter with identical configuration of the stages
Inventor: BACKES REINER DIPL ING
IPC: H03K23/42
Filed: 1982-03-30
Abstract: A first variant of a dynamic synchronous binary counter having identical configuration of the stages, which is activated with non-overlapping clock signals in the usual two-phase ratio circuit technique, consists of the following series circuit with respect to signal flow: first inverter (I1) - complex gate (KG) - first transfer transistor (T1) - second inverter (I2) - third inverter (I3). The complex gate (KG) consists of two NOR-type AND gates (U1, U2). The output of the second inverter (I2) is the up-counting output (VA) and that of the third inverter (I3) is the down-counting output (RA). The up-counting output (VA) is connected via the third transfer transistor (T3), controlled by the second clock signal (F2), to the first input of the AND gate (U1), the second input of which is connected to the output of the first inverter (I1). The down-counting output (RA) is connected via the second transfer transistor (T2), controlled by the second clock signal (F2), to the first input of the AND gate (U2), the second input of which is connected via a fifth transfer transistor (T5), controlled by the clock signal (F2), to the output of a NOR gate (NG). One input of the NOR gate (NG) is connected to the carry input (UE) of each stage. This input is connected via the carry transfer transistor (UT) to the carry output (UA). The carry input (UE) of the least-significant stage is connected to circuit zero. The second input of the NOR gate (NG) is connected to the stop line (S). The carry output (UA) is connected via a fourth transfer transistor (T4), controlled by the down-counting output (RA), to the constant voltage (U). In a second variant, the complex gate (KG) is omitted so that the output of the first inverter (I1') is directly connected to the input of the second inverter (I2') via the first transfer transistor (T1'). Furthermore, the output of the NOR gate (NG') controls the gate of the second transfer transistor (T2'). The first input of the NOR gate (NG') is fed by the clock signal (F1'), the second input is connected to the carry input (UE). The ends of the current paths of the transfer transistors (T2', T3') facing away from the output in each case lead to the input of the first inverter (I1'). <IMAGE>
