Patent DE-3480831-D1 (DE)
Inventor: BAUER PETER
IPC: F15C1/22
Filed: 1984-12-31
Granted: 1990-02-01
Abstract: A small, but nevertheless high-flow fluidic oscillator has a dual level body portion including an interaction chamber in a first level. An inlet plenum supplies fluid to a supply nozzle which enters directly into the inlet end of the interaction chamber to direct a jet flow from the supply nozzle, through the interaction chamber and out of an outlet opening. A fluid passage is located at least partly in the second level of the body portion, and connecting passages on either side of the supply nozzle connect the fluid passage to the inlet end of the interaction chamber. The walls of the interaction chamber converge from the inlet end toward a neck portion and thereafter diverge and then converge again at the outlet so that a fluid column extends between the jet flow and the sidewalls of the interaction chamber, and moves cyclically back and forth through the fluid passage and the connecting passages to obtain interaction between the fluid column and the jet flow without the need for control nozzles.

Granted: 1994-05-11
Abstract: An electronic ballast circuit for fluorescent or other gaseous discharge lamps includes a resonant half-bridge inverter circuit. The source voltage to the inverter is a full-wave rectified line voltage together with a DC carry-over voltage for supplying power in the inter-cusp period of the rectified line voltage. A negative feedback circuit is responsive to lamp current to vary the inverter drive frequency and thereby regulate lamp current. The frequency response of the feedback loop is high enough and the gain-versus-frequency response of the inverter is such that lamp current and voltage are regulated to reduce the crest factor of lamp current to compensate for variation in the amplitude of the voltage across the semiconductor switches.

Abstract: A stream of high-speed bipolar signals (18) (19) transmitted along standard twisted pair (13) telephone wiring are detected by a circuit (10) that includes a pair of differential amplifiers (20) (21) each having a signal input (11) (12) connected directly to one conductor (14) (15) of the twisted pair (13) and a reference input (22) (23) connected through a peak voltage detector (29) to the opposite conductor (14) (15). The amplifiers (20) (21) function as an input signal comparator which generates a corresponding bit stream of logical ones in response to the bipolar signals that exceed 50% of the average peak voltage input. A threshold bias voltage corresponding to positive going signals on each conductor (14) (15) is generated by the detector (29) and charges separate capacitors (37) (39) that connect each reference input (22) (23) to its conductor (14) (15). The bias voltage and bipolar signals input to each amplifier (20) (21) are algebraically summed which doubles the differential input signal and results in an increased signal to noise ratio of about six decibels.

Abstract: A method is described that dedicates specialized ribosomes to the synthesis of desired proteins. DNA which encodes rRNA having a mutant anti-Shine-Dalgarno sequence is used to transform a host cell in combination with DNA encoding messenger RNA for the desired protein having a complementary mutant Shine-Dalgarno sequence. Since the mutant sequences are selected so as to be substantially unrecognized by either endogenous messenger RNA or ribosomes, respectively, the synthesis of protein proceeds in a dedicated system without interference from other host cell protein synthetic machinery.

Abstract: A common optical path interferometric gauge comprises an optical beam that is split into two beams. Both beams are modulated and recombined after introducing an optical path length difference greater than the coherence length of the optical source. The combined beam is guided along a common optical path and is subsequently split into reference and measurement beams. The measurement beam is guided along a measurement optical path that includes a moving workpiece surface. Both beams are recombined after interposing an optical path length difference therebetween so as to reestablish coherence between portions thereof, producing optical interference indicative of the surface movement.

Abstract: The driving speech of the vehicle is automatically limited such that a continuous speed is not exceeded that results in acceleration-independent motion-resistances corresp. to the nominal operation of the electric drive. From the actual motion-resistances and the nominal power, a max. constant speed is determined which is compared with the current speed and a reduction in drive power to the nominal value when the speeds are the same. Alternatively, the power is restricted when the difference between the electric input power and the electric nominal power is greater than the acceleration power divided by the efficiency of the drive. The limitation is by restricting the current to its nominal value, and is carried out with a few seconds time-constant.
