Patent DE-2943303-A1 (DE)
Inventor: BESSON RENE
IPC: G04D7/12
Filed: 1979-10-26
Abstract: An electronic watch comprises a stepping motor 6 for driving a mechanism for displaying the time information, a quartz crystal controlled oscillator 1, a frequency divider 2 with an adjustable division ratio, a circuit 7 for adjusting the division ratio eg by suppressing a number of pulses from the oscillator to the divider, a memory 8 containing data corresponding to the number of the pulses to be suppressed in each adjusting, cycle and a logic circuit 10 which, in response to an interrogation signal, (switch 9) produces a measuring signal at the output of gate 19 which is supplied to the coil of the stepping motor and which comprises a series of pulse trains whose distribution is representative of the division factor and the frequency of the oscillator and whose duration is sufficiently short so as not to cause the motor to rotate and sufficiently long to cause a magnetic stray field from the motor which can be detected by an external apparatus for measuring therefrom the rate of the watch. The interrogation signal upon closure of switch 9 causes the divider to divide with its unadjusted value. A gate 11 is enabled by 1 Hz pulses at 11a to pass trains of 256 Hz pulses in alternate half quartz-second intervals. The pulses pass through the gate 19 until their number, counted by counter 17, equals the adjustment number eg 5 held in memory 8. The interrogation signal also acts on switch circuit 4 to disconnect the motor control inputs at 4a 4b of circuit 5 from the divider 2, and apply the measuring signal pulses at input 4e from the gate 19 instead. In the embodiment described, a "quartz-second" is shorter than a normal second, the watch crystal frequency being higher than a nominal frequency, alternatively the measuring signal may be transmitted acoustically. The external measuring apparatus is described in App No. 79/36415. <IMAGE>

Title: Modulated pulse system for converter control - uses ring of monostable time base circuits to synchronise switching between inputs and outputs
Inventor: VENTURINI MARCO
IPC: H02P27/04
Filed: 1980-03-06
Abstract: The converter with inputs for a symmetrical multi-phase a.c. voltage system and several bidirectional switches connecting the inputs with the outputs uses a control system with a time controller. This generates a repeated set of modulated pulses corresponding to the number of phases of the system. These operate the closing of the switches so that each phase of the input is connected with each phase of the output and at any given instant, only one switch is closed, between input and output. The output a.c. voltage system may be a single or multiple phase system. For each output, a pulse train is applied to a switch, the relationship between the pulse train and the input being displaced cyclically. The timing system uses a ring of monostable time base circuit.

Title: Unit for delivering liquids
Inventor: GRAF GERNAND
IPC: F04D5/00
Filed: 1981-05-09
Abstract: A liquid-delivery unit is proposed which, in particular, serves for delivering liquid fuel to an internal-combustion engine. The unit has a delivery member which revolves in a chamber and on whose two end faces, which are parallel to the plane of rotation, one blade ring each is arranged. Assigned to each blade ring there is a side channel, the side channels being arranged in the chamber walls adjacent to the end faces of the delivery member. The two side channels are connected to one another. The intake zone of the upstream side channel, in terms of the liquid to be delivered, of a first pump stage has an inflow orifice for the liquid, and the discharge zone of the first pump stage merges into the input zone of the other, second pump stage. The output of the second pump stage is arranged behind, in terms of the direction of rotation of the delivery member, the transition between the two side channels. In order to have the delivery member, designed as an impeller, revolving with the moments balanced, the forces acting on the one delivery member end face are counteracted by balancing forces acting on the other delivery member end face which support the delivery member in its plane of revolution. <IMAGE>
