Patent EP-0239793-B1 (EP)
IPC: H05B41/298
Filed: 1987-02-26
Granted: 1991-07-03
Abstract: A circuit for operating low-pressure discharge lamps at elevated frequency comprises a reconnect circuit which disables the disconnect circuit upon exchange of a defective low-pressure discharge lamp (LP1). The disconnect circuit comprises a diode (D10), a resistor (R11) and a thyristor (TH) together with a trigger circuit (5). The reconnect circuit comprises a capacitor (C9) and a resistor (R12). Upon removal of the defective low-pressure discharge lamp (LP1), the capacitor (C9) is charged over the resistor (R12). Upon insertion of a new low-pressure discharge lamp (LP1), the capacitor (C9) is discharged and recharged in opposite direction and the holding current is removed from the thyristor (TH). This causes the thyristor (TH) to block, and enables the push-pull frequency generator (3) to start oscillating again.

Abstract: A one piece self closing dispensing valve (1) of molded polymer material is used in combination with a beverage container. The valve is of the kind containing a movable actuator (5) which in response to a force applied thereto by a user, such as pressure exerted by the users finger, opens the valve to dispense liquid under force of gravity. A leaf spring (4) operable over the range of actuator movement and normally biasing the actuator responds to the withdrawal of the applied force to return the actuator to its normal position and thereby close the valve. An integral dripless spout is defined between the actuator and the valve body; the effective size of which is inversly dependent on the position of the actuator.

Abstract: The direct acting air brake for railway vehicles comprises a time controlled driver brake valve 12, a relay valve 7 controlled by this and brake cylinders 19, the pressure applied to which by the relay valve 7 via pipelines 14, 17 being monitored. The brake pressure prevailing in the brake cylinders 19 is displayed by a pressure gauge 22. In order to prevent trailing or lagging of the brake pressure prevailing in the brake cylinders 19 after completion of an actuation of the driver brake valve 12, an air reservoir 24 is connected to the control inlet 6 of the relay valve 7 via a nozzle 23. The nozzle 23 and the air reservoir 24 are matched to the flow resistances in the pipelines between the relay valve 7 and the brake cylinders 19 in such a way that on completion of an actuation of the driver brake valve 12 they generate an equalisation pressure on the control inlet 6 which corresponds to the instantaneous brake pressure prevailing in the brake cylinders 19 at the end of actuation. The air brake facilitates simple and precise control of specific brake pressures to be observed by means of the pressure gauge 22. <IMAGE>

The data sequences are detected and combined with the auxiliary signal to generate a phase adjustment signal (54) with a uniform representation corresponding to the various data bit sequences and having an average value depending upon the phase difference between clock signal and data signal. Further, a reference signal (55) may be generated, representing the average value of the phase adjustment signal (54) which responds to ideal phase state. This reference signal (55) in combination with the phase adjustment signal (54) may be used for an even more precise adjustment of the phase of the clock generator with respect to the data signal.
