Title: Arrangement to limit the terminal voltage in an alternator
IPC: H02H9/04
Filed: 1991-03-07
Abstract: An arrangement for limiting the terminal voltage in an alternator has a fixed stator winding acting on rectifiers and an excitation winding which rotates with the alternator rotor. The arrangement also has a controller and a first slip ring contact which load the excitation winding with excitation current as a function of the magnitude of a delivered voltage, and at least one free-wheeling valve which is conductive during a controller-side interruption of the excitation current and is connected in parallel with the excitation winding. The arrangement includes an auxiliary winding on the rotor. The auxiliary winding continues the excitation winding in the same direction of winding, with the auxiliary winding and the excitation winding being connected at a first connection point. A second slip ring contact operatively connects the first connection point to a machine terminal supplying excitation current. A zener diode is connected in series with auxiliary winding, and a third slip ring contact operatively connects the auxiliary winding to a ground terminal of the alternator or of the controller.

Title: Horizontal rotating reactor with moving bed for biotechnoligical processes
IPC: C12M1/10
Filed: 1992-04-03
Abstract: In a horizontal reactor with rotating drum which is substantially filled with biomass-covered packing elements, the degradation efficiency and the technical optimisation of flow are improved when the drum is divided in the axial direction into at least two chambers by transverse walls which retain the packing elements so that material once present in a chamber remains there throughout operation but which have a liquid-permeable perforation, which are formed, in particular, by bar screens which project from the transverse wall on both sides into the adjacent chambers in each case, are formed by a ring of bars and are in the form of a tubular connector with terminal closure and which are partly filled with sharp-edged packing bodies. Axial ribs projecting inwards from the drum and offset from chamber to chamber are provided. Deflecting plates are preferably located within the individual chambers and have, towards the drum casing, an annular slit for the flowing liquid of, in particular, 5 - 10% of the drum diameter. The division into chambers makes graduation of the chamber size possible, it decreasing in particular towards the liquid outlet. It is furthermore possible for the support materials to differ in particle size or nature from chamber to chamber. <IMAGE>

Title: Image generator.
Inventor: BAKER STEPHEN JOHN
IPC: G06T15/00
Filed: 1989-12-05
Abstract: An apparatus for generating an image to be displayed on a display screen from data defining a model including a plurality of opaque and translucent features. The image is intended to represent a view of the model from a predetermined eyepoint and is made up from an array of screen space pixels to be displayed by a raster scanning process. Each pixel is of uniform colour and intensity, and the pixels together define an image area. The image area is divided into an array of sub-areas each of which covers at least one pixel. For each feature in the model that is potentially visible from the eyepoint, a test is conducted to determine which of the sub-areas is at least partially covered by that feature. A list of feature identifiers is produced in respect of each sub-area, the list for any one sub-area identifying features which at least partially cover that sub-area. The position in screen space of at least one sampling point within each sub-area is determined. For each sub-area in turn, and for each sampling point a test is conducted to determine which of the features in that sub-area's list cover that sampling point. For each feature which covers a sampling point, a function of the distance from the eyepoint to that feature at the sampling point is determined. Feature describing data is stored for each sampling point within a sub-area, the stored data being indicative of at least the distance of the opaque feature which covers the sampling point and is nearest to the eyepoint and the distance and translucency of at least one nearer translucent feature which covers the sampling point. An output is produced for each sampling point within a sub-area, the sampling point output corresponding to the combined effects of the features identified by the stored data. An output for each pixel within a sub-area is produced, the pixel output corresponding to the combined effects of the sampling point outputs for all sampling points which contribute to that pixel, and the pixel outputs are displayed. <IMAGE>

IPC: H04B17/336
Filed: 1995-03-13
Abstract: In accordance with the invention, the incoming receiver signal is subject to an envelope demodulation by means of a measuring receiver 2. Subsequently, for a defined measurement time Tges) in defined time differences  DELTA T, the signal is sampled and digitized via an analog/digital converter 3 and stored in a computer 4 as a consecutive sequence of 1-N values of the square of the envelope function R2(t). From these stored values the auxiliary values X' and Y' are generated, whereby Y' is corrected by means of an appropriate correction factor k. Then, the C/I ratio is determined via the proper procedures. The method of the invention distinguishes itself in that, with relatively little expenditure and taking into consideration the typical features of the GSM mobile communication network, and based on the receiving power as a function of time, the C/I ratio is determined from the values of the function of this time function by means of an analytical calculation.

Abstract: Continuity of coordinates between areas of a
coordinate input surface which is divided into a
plurality of areas is maintained. In inputting "A, B,
C" on a coordinate input plate, when an input operation
is started from an initial point (a), area 1 is
determined as an input area, and vibration delay times
are measured by using sensors (6a, 6b, 6d), thereby
calculating a coordinate value. When the input
operation is continued up to a terminal point (a'), the
input point shifts to area 3. However, vibrations are
detected by using the same sensors (6a, 6b, 6d) to
calculate a coordinate value as long as the input
operation is continuously performed. With this
operation, since sensors are not changed for the
respective areas, discontinuity of lines at the
boundaries between the areas can be prevented.

Abstract: An electronic imaging device employs black
pattern correction for dark current in a charge
transfer image sensor. The sensor is composed of image
pixels having a characteristic black pattern of dark
current in which the amplitude of the dark current for
each pixel is dependent upon exposure time. A reference
dark frame exposure is captured from the image sensor
in the absence of light and dark frame pixel values are
obtained. An exposure section regulates the exposure
time of image light upon the image sensor and provides
a corresponding plurality of image frame exposures; the
image sensor thus generates a corresponding plurality
of image frames each comprised of image frame pixel
values. A processor then generates a correction factor
from the dark frame pixel values and applies the
correction factor to the image frame pixel values for
the plurality of image frames to obtain corrected image
frame pixel values that are modified for the black
pattern. As a result, performance efficiency is
increased by using a single reference dark frame
exposure in the correction of many image frame
exposures.

includes two lasers: a reference laser and a slave laser. Each
laser is a weapon, and when locked on a target, single laser
effectiveness may be doubled without a thermal blooming
performance loss associated with a single laser operating at twice
the power. The slave laser beam is dithered relative to the
reference laser beam in a direction along the longitudinal axis of
the target. The system includes an optical receiver for
repetitively scanning the irradiance profile reflected by the
target. Since the slave laser beam is dithered relative to the
reference laser beam, both laser beams will jitter and drift
together providing a gain factor of two in average irradiance on
the moving target.
