Title: Method for the internal cleaning of branched pipings and/or units, and device for carrying out this method
IPC: B08B9/02
Filed: 1987-09-15
Abstract: In the method the pipes and the units are flushed out with a liquid cleaning medium. It is proposed that a common cleaning medium supply be provided, from which several pipes and/or units are flushed in parallel connection. The total flow volume in the main pipe is measured and in addition the respective flow volume in each of the pipes or in each of the units to be cleaned is measured. The flow volumes in each of the pipes to be cleaned can be adjusted by means of devices provided for this purpose. As a result the branched pipes and/or units can be uniformly flushed out according to the individual cleaning requirements. A suitable device for carrying out the process is also described. <IMAGE>

Title: Video camera with a target
IPC: H04N5/228
Filed: 1987-10-02
Abstract: In television cameras, there is a risk that the image will wobble due to an unwanted movement of the housing. According to the invention, a television camera is provided with a target onto which a desired image field is projected by means of optics and which is scanned along a raster in order to generate the video signal, the target being larger than the field of view and an actuating variable being obtained from a movement of the camera, which variable allows the starting point of the scanning raster on the target to be displaced. The actuating variable is obtained in a comparator or correlator which compares the image signals of successive frames or parts thereof and, in the case of a signal difference above a threshold value, generates the threshold variable. <IMAGE>

Title: Method for manufacturing a paper or cardboard product and a product manufactured by the method
IPC: D21H19/36
Filed: 1988-12-01
Abstract: The invention relates to a method for manufacturing a paper 
or cardboard product and to a product manufactured by the 
method. According to the invention, a cellulase enzyme is 
added to the product during manufacturing, said enzyme 
causing the product to decompose when exposed to moisture. 
The enzyme can be introduced into the product in connection 
with surface sizing, pigment coating or calendering, or it 
can be added in the form of a solution which is separately 
applied to the product in the dry end region of the paper 
or cardboard machine. Experiments have shown that a product 
manufactured as taught by the invention can be provided 
with a plastic coating without risk of destroying the 
enzyme. Cardboard produced by the method of the invention 
can be used in the manufacture of packages for liquids, of 
packing boxes or disposable containers, the cellulase 
enzyme serving to promote decomposition of the products 
after they have been brought as waste to dumping areas.

Title: Color liquid crystal display device and method for driving same
IPC: G02F1/1343
Filed: 1989-04-13
Abstract: A color liquid crystal display device comprising 
light shielding layers (4) and color filters (3) on the inner 
surface of a cell, wherein similar light shielding layers 
and color filters are disposed also in a peripheral 
region outside of a display region which is equipped with 
groups of striped row and column electrodes (10) opposed 
mutually to form pixels for display. The respective 
patterns of the light shielding layers and the color 
filters are the same in both the display region and the 
peripheral region. A liquid crystal layer formed in the 
display device has a twist angle of 160° to 300°, and a 
retardation compensator composed of a film is superposed 
on such layer so as to compensate the elliptical 
polarization. And a non-selective voltage is applied 
continuously to the scanning electrodes in the peripheral 
region so as to maintain the peripheral pixels in a 
light-shielded state, thereby rendering the display 
easier to be seen. Furthermore, due to overlaps of the 
color filters and the light shielding layers in both the 
display region and the peripheral region, the gap between 
the substrates (8) is retained substantially uniform to 
minimize the nonuniformity of the backgroud color.
