Abstract: Beschrieben wird ein leistenförmiger Betonabstandhalter (1) 
mit einer Tragleiste (2) und zwei an diese unter Ausbildung 
eines U-förmigen Querschnitts angeformten Stützleisten (3,4). 
An der Tragleiste (2) ist auf ihrer 
den Stützleisten (3, 4) gegenüber­
liegenden Seite mindestens eine, etwa 2-4 mm hohe Längsrippe 
(14 bzw. 15) angeformt, welche in regelmässigen Abständen mit 
Querrillen (17 bzw. 18) versehen ist. In die Querrillen (17 bzw. 18) in 
der oder den Längsrippen (14 bzw. 15) 
eingelegt, erfahren die Armierungs­
eisen (9, 10) eine recht gute Stabilisierung gegen seitliches 
Verrutschen. Dadurch dass die Querrillen (17, 18) in regelmässigen 
Abständen angeordnet sind, ergibt sich automatisch der 
erwünscht gleichmässige Abstand der Armierungseisen voneinan­
der. Das aufwendige Abmessen der Abstände sowie das aufwendi­
ge Ausrichten der Armierungseisen auf der Baustelle erübrigt 
sich. Andererseits ist durch die geringe Höhe der Längs­
rippe/n von nur 2 bis 4 mm und der dadurch bedingten ent­
sprechend geringen Tiefe der Querrillen sichergestellt, dass 
auch andere Abstände, als die durch die Folge der Querrillen 
vorgegebenen gewählt werden können.

Title: Apparatus and method for making large area electronic devices, such as flat panel displays and the like, using correlated, aligned dual optical systems
IPC: G03F7/20
Filed: 1988-09-05
Abstract: Apparatus for projecting multiple images from a 
pair of reticles (117) onto a photo-sensitive coated 
substrate (1) to produce large scale electronic 
devices, comprises a pair of parallel and proximate 
optical systems (13,15), which are positioned to 
project in the z-direction upon a movable stage (11) 
subject to controlled motion in the x- and y-direct­
ions, means for determining the coordinates of motion 
of the stage (11) relative to images projected from 
the reticles, means for using the determined positions 
to establish a stage transfer function for the appar­
atus relative to various positions of stage, and means 
for applying the transfer function to adjust the 
relative positions of the reticles (117) and substrate 
(1) for accurate image projection, and for thereafter 
projecting an image (R1, L1) upon the substrate. The 
stage (11) is then stepped to a position to permit 
projection of an abutting image, and the transfer 
function is used to adjust the relative positions of 
the reticles (117) and substrate (1) for accurate 
image projection for projecting the abutting image upon 
the substrate 91). The steps are repeated until 
sufficient images have been projected upon the sub­
strate to make up one integrated layer of a flat panel 
display or other large scale electronic device. After 
treating the photosensitive layer, subsequent layers 
are produced in a similar manner.

Title: Video tape recorder having picture-in-picture function
IPC: G11B27/028
Filed: 1989-04-21
Abstract: A video tape recorder (1) is associated with a monitor (2) 
to provide sub-picture images at portions (2a, 2b) of the 
monitor screen (2p) for use in editing a recorded tape (12) by 
inserting an input video signal. First and second 
memories (17a, 17b) are provided with respective capacities 
sufficient to store a field or frame of a video signal 
reproduced from a tape (12) or of an input video signal, and 
writing and reading of the memories (17a, 17b) are controlled 
to provide sub-picture signals for display at the respective 
portions (2a, 2b) of the monitor screen (2p). When playback or 
playback-pause modes are selected, one of the sub-picture 
screen portions (2a, 2b) displays the reproduced video signal 
as a moving picture or as a still picture, respectively. Upon 
change-over to the recording-pause mode, one of the 
sub-picture screen portions (2a, 2b) continues to display a 
still picture of the reproduced video signal at the moment of 
selection of the playback-pause mode and which may be the 
selected edit-in point, and the other sub-picture screen 
portion (2a, 2b) displays the input video signal as a moving 
picture so as to facilitate determining the point at which 
change-over to the recording mode is effected for recording 
the input video signal in place of the video signal previously 
recorded on the tape (12).

Patent EP-0368162-A3 (EP)
Title: Method of and apparatus for performing detail enhancement
IPC: G06T5/20
Filed: 1989-11-03
Abstract: Detail enhancement is achieved by producing an 
enhanced image signal (ES) on the basis of a sharp signal 
(S), a middle signal (M) and an unsharp signal (U). The 
sharp signal represents density of a pixel, the middle 
signal represents weighted means density of a first area 
larger than a pixel and the unsharp signal represents 
weighted mean density of a second area larger than the first 
area. Three differential signals (S - M, S - U, M - U) are 
obtained and multiplied by respective coefficients to become 
three enhancement signals. The enhanced image signal is 
obtained by adding the sharp signal and at least one of the 
three enhancement signals so that the detail enhancement is 
achieved at a middle range of spatial frequency.

Title: An open cassette and a method of winding a tape therein
IPC: B65H75/30
Filed: 1989-01-27
Abstract: The invention relates to a cassette (1) for winding a tape 
(2) and retaining it as a reel, including a frame surrounding 
the reel with a central guide member (5), which radially outwards 
delimits the inner periphery (3) of the reel and radially inwards de­
limits an opening (6) in the centre of the reel. the frame consists of 
a framework comprising at least two flat, rigid frame bands (1) sym­
metrically crossed and interconnected on the back side of the 
reel, which on the said back side extend radially outwards from 
their point of intersection, round the outer periphery of the 
reel and then extend again radially inwards along the front side 
of the reel, forming finally as the said guide members hooked 
claws (5), which extend axially across at least a portion of the inner 
periphery (3) of the reel. This open reel construction is most appro­
priate for a winding method, in which a winding member (4) is inserted 
inbetween the said frame bands and is brought into firm contact 
with the reel for the tape to be wound onto this. Two embodiments 
of such a winding method have been described.
Patent EP-0353835-A3 (EP)
Title: Technique for reducing distortion characteristics in fiber-optic links
IPC: H04B10/54
Filed: 1989-03-28
Abstract: The present invention relates to a technique for suppressing 
intermodulation products introduced by nonlinearities of a laser in a multi-­
carrier Frequency Division Multiplexed (FDM) fiberoptic link. More 
particularly, for two or more closely spaced FDM channel information 
signals within a predetermined band of frequencies in an FDM optical 
transmission system, third-order intermodulation products, which are 
produced by nonlinearities of a transmitting laser, also fall in-band and 
provide interference in the channel information signals. Suppression of 
these in-band intermodulation products is achieved in the present invention 
by the simultaneous transmission of a strong suppression tone (44) which is 
disposed outside the band of the FDM channel information signals (40, 41) 
being transmitted, and at a frequency within the overall response band of 
the transmitting laser (24) such that the mixing of the channel information 
signals and the suppression tone will provide minimal, or no, 
intermodulation products (42, 43) in the frequency band of the the FDM 
channel information signals.

Patent EP-0385145-A3 (EP)
IPC: H01M10/44
Filed: 1990-02-07
Abstract: A new accumulator battery of the lead-acid type is described, having freely mobile electrolytes which can be circulated by means of pumps, and a new multistage charging method which follows a scheme in which a predetermined first voltage limit U1 = 2.30 V/cell is initially achieved with a relatively high constant current i1 and, thereafter, a second voltage limit U2 = 2.40 V/cell is achieved with a reduced constant current i2, and in which a constant voltage charge with U2 concludes the charging method. When the charging current i, which falls in this phase, passes through the current range from 0.08 CA>/=i>/=0.02 CA, this defines the end of the charging time tA, which is just required for a 100% charge, but is not adequate to maintain the capacity over a long operating time. The charging apparatus therefore receives a signal for further charging by a time factor a and, for safety reasons, by an additional timing element K. The switching voltages U1 and U2 can be temperature-regulated depending on the temperature dependence of the charging voltage of lead-acid accumulators. With a charging factor f = 1.03, a battery operation of up to over 200 charge/discharge cycles or 1 year's duration is possible, with minimum water losses, without reduction in capacity. <IMAGE>
