Abstract: A geared motor unit (1) for door opening devices and the like comprises a worm screw (3) and helical wheel (5) assembly carrying a shaft (9) substantially orthogonal to the plane of the helical wheel (5), and a second reduction assembly made up by two pairs of cylindrical gear wheels (17, 19, 21, 23) meshing together, from which assembly protrudes the shaft (25) carrying the actuating arms for the door to be rotated. 
     Such geared motor unit (1) is equipped with an emergency device adapted to disengage the worm screw (3) and helical wheel (5) assembly from the assembly of the gear wheels (17­23) and to allow for the rotation by hand of said assembly which would be otherwise impossible due to the irreversible coupling of the worm screw (3) and helical wheel (5) assembly; said device consisting of a flat grooved plate (35) engaging (at 37) with resilient means (43) the lower face (29) of the helical wheel (5), which plate is fixed (at 47) to the shaft (9) which in turn is carried idle on the helical wheel (5). In an emergency situation it is only necessary to actuate a foreseen hand grip (57) provided with a fork (51) at the top of said shaft (9), which causes the lowering of said shaft (9)   coaxial to the helical wheel (5) and the consequent lowering of the flat plate (35) integer with it. 
     The geared motor unit (1) of the invention provides for a d.c. electric circuit comprising a d.c. motor (7), a control relay (71), control pushbuttons (73) and an emergency relay (77) connected to an electronic circuit (81) provided with pressure sensors (85), a thermal stabilizer (87), a dynamic compensator (89), a signal amplifier (91), Schmidt triggers (93, 95) and a combinational logic circuit (97) adapted to analyze the signals from said circuit and to forward them to the anticrushing control circuit (99) with associated inhibit relay (79).

Abstract: Voltage-controlled oscillator provided with a frequency-­determining element and an oscillator loop having a phase-rotating network, in which the value of one or more elements depends on a control signal which is fed to a control input and with which the phase rotation and thereby the oscillator frequency can be changed. The oscillator is further provided with a phase control loop, at least comprising a phase-rotating network to the input of which the oscillator signal is fed, a phase detector to the two inputs of which the input signal and the output signal of said phase-rotating network are fed, and an amplifier which amplifies the output signal of the phase detector and feeds it to the control input of the phase-rotating network of the oscillator loop. The phase detector has an accurately known and temperature-independent input-output relation. The phase-rotating network of the phase control loop may be formed by the phase-rotating network of the oscillator loop (Fig. 2). Said oscillator loop may have at least two cascaded phase-rotating subnetworks, at least one of which has said phase control loop with phase detector and amplifier (Figs. 3, 4, 5).

Abstract: The exchange device (not shown) is installed in a lock and emits a modulated carrier wave. The key (2) possesses circuits (27, 28, 29, 23) for demodulating the modulated carrier wave received and for reconstructing a first signal (PR) representing the information emitted by the exchange device, and processing circuits (23, 25, 30) receiving the first signal (PR) and generating a second signal (D) representing the information to be transmitted. The second signal causes an impedance (26) to vary abruptly, so that the charge detected by the exchange device varies and so that the information is thereby transmitted to it. Moreover, the impedance (26) is designed as a limiter. A clock signal (41) is obtained from the modulated carrier wave by clipping, and the supply voltage (AC) is obtained by rectification and regulation. The system makes it possible particularly to use a contactless connection between the key and the lock, for example by means of a single pair of coils. <IMAGE>

Abstract: The present invention is a variable blending dispenser (8) for fluids, particularly for fuel dispensers. The dispenser controls variable valves (16,18) according to volumetric data observed by flow meters (26,30) on input lines to the dispenser, by calculating measuring error as the difference between desired blend ratio and the observed blend ratio calculated from volumes of blend components dispensed. The dispenser successively corrects the settings of the valves after dispensing predetermined volumes, the corrections determined by a volume based PID error function so that the total amount of each blend component is separately and accurately measured while providing the desired blend ratio.
