Title: Method and control arrangement for controlling the output voltages of two dc supply devices
IPC: H02M3/137
Filed: 1989-09-18
Abstract: The output voltages (Ud1, Ud2) of two D.C. choppers (7, 9, 72, 92) connected in series on the input side are to be controlled. For this purpose, the sum voltage (U SIGMA  = Ud1 + Ud2) and the error voltage (U DELTA  = Ud1 - Ud2) of the output voltages (Ud1, Ud2) of the D.C. choppers are formed as secondary controlled variables. The sum voltage (U SIGMA ) is compared to a desired value of the sum voltage (U SIGMA Soll), and fed to a sum-voltage controller (10). The error voltage (U DELTA ) is compared to a desired value and fed to an error-voltage controller (11). The output signals of the two controllers (10, 11) are added or subtracted from one another and used in this way to form the pulse duty factors (a1, a2 and a11, a12, a21, a22 or a1H, a1T, a2H, a2T) for controlling the D.C. choppers. <IMAGE>

Title: Filter circuit arrangement
IPC: H03H11/04
Filed: 1989-10-16
Abstract: A filter circuit (2) is automatically tuned so that the 
positions of the poles and zeros of its frequency response 
characteristic are maintained in substantially fixed ratios to an 
input frequency (f r ). To this end the arrangement comprises a 
frequency discriminator (1) having its output 5 coupled to a 
controllable element (8) of a resonant circuit included therein, 
so that the resonant frequency of the resonant circuit is 
maintained equal to the input frequency. The output 5 also 
controls a counterpart (13) to element 8, which counterpart is 
included in an auxiliary circuit (3). The filter circuit is 
tuned by controlling an element (10) included therein, which 
element also has a counterpart (14) included in the auxiliary 
circuit, both these last elements being controlled by the 
auxiliary circuit output signal. The auxiliary circuit output 
signal is determined by the ratio between parameters of the 
respective counterpart elements (13,14) which correspond to 
parameters of the tuning elements (8,10) which govern the tuning 
frequencies, and acts to maintain this ratio, and hence the 
aforementioned ratios, substantially constant.

Title: Apparatus for laser sculpture of the cornea
IPC: A61F9/008
Filed: 1989-06-08
Abstract: In use of laser radiation to ablate corneal tissue, to achieve a sculptured change in curvature of the optically used region of the cornea, a variable magnification (zoom) lens is combined with different sized apertures of an indexible mask to develop a relatively smooth profile for the changed curvature. The zoom-lens settings are varied in the course of cornea exposure through each of the succession of mask apertures. To do this, the range of zoom-lens magnification can always be less than 2:1, yet the zoom-lens system can effectively reduce to insignificance the stepped profiling that is inherent in reliance only upon the indexed aperture technique. Also described are techniques to achieve compensation for delivered flux-density variation as a function of instantaneous zoom-lens setting, and programmable control of the area of delivered flux density in a manner to correct for parabolic or other fall-off in delivered beam intensity as a function of radius outward of the axis of beam delivery.

Title: Polarizing beam splitter apparatus and light valve image projection system
IPC: G02F1/1335
Filed: 1990-03-20
Abstract: Disclosed are a polarizing beam splitter apparatus 
having a polarizing beam splitter (22) commonly usable as a 
polarizer and an analyzer, and a quarter wave plate (25) in 
combination; and a light valve image projection system using 
the same. In the polarizing beam splitter apparatus, a 
quarter wave plate (25) is arranged in a light path along which a 
light goes out from and goes back again to the polarizing 
beam splitter (22) in such a manner that either a fast optic axis (28) 
or a slow optic axis (29) of the quarter wave plate (25) is 
perpendicular to a plane containing an incident optical axis (30) 
and an reflection optical axis (31) of the polarizing beam (22) 
splitter, so that the angular range of a light to be used 
can be increased. In the light valve image projection 
system, a light outputted from a light source (21) is incident 
through a polarizing beam splitter apparatus to a light 
valve, and an effective component of the light reflected 
from the light valve (26) is projected through the polarizing 
beam splitter apparatus and a projection lens (27) on a 
projection screen. The polarizing beam splitter apparatus 
of this invention is high in polarization efficiency even if 
the range of incident angle of a light to be used is large, 
so that a projected image highly improved in contrast and 
brightness can be obtained.

Title: Installation for sludge dewatering.
Inventor: SKOCIC ANTE
IPC: B01D33/46
Filed: 1993-12-22
Abstract: The novel installation for pressure dewatering of sludge contains an elongate pressure vessel which is fitted with at least one filter candle orientated parallel to the axis. The wall of the pressure vessel is covered with a filter drum through which flow passes outwards. The discharge of the dewatered sludge is opposite the feed so that the sludge moves through the pressure vessel along the filter surfaces with continously increasing dewatering. During this it is supported by rotated 10 transport devices, such as ring spirals. The counterpressure for the filtration is generated at the sludge discharge orifices by throttling the cross-section or by connection of a helical-screw pump which is continuously controllable from the idle state on. Vibrations or shock-like reversal of flow prevent blocking of the filter gap. <IMAGE>
