Title: Process for manufacturing alkali hydroxide, chlorine and hydrogen by electrolysis of an aqueous alkali chloride solution in a membrane cell
IPC: C25B15/08
Filed: 1987-11-09
Abstract: Alkali hydroxide, chlorine and hydrogen are produced from an aqueous alkali chloride solution by membrane electrolysis. A high-NaCl solid salt, which contains impurities, is dissolved in water in a salt dissolver. Precipitating chemicals are added to the salt solution to precipitate the impurities. The resulting mixture is fed to a thickener, from which precipitates and clarified raw brine are separately withdrawn. The clarified raw brine from the thickener is divided at a ratio between 2:1 and 20:1 into first and second partial streams. The larger first partial stream is mixed with the salt solution and the precipitating chemicals before entering the thickener and the resulting mixture is fed to the thickener. The second partial stream of the clarified raw brine is fed through a fine purifier to the electrolytic cell. Spent brine from the electrolytic cell is fed to the salt dissolver.

IPC: G01F11/28
Filed: 1987-06-09
Abstract: A device (1) for dispensing a non-fluid chemical product can be 
made without the need for a spray head. This device is of the kind 
where the product is dispensed as a dosing liquid 
comprising a solution and/or dispersion thereof in a solvent, wherein 
the device is separated by a liquid-pervious screen 
(10), into an upper chamber (8) in which the product is to be held, 
and a lower chamber (14) provided with an inlet (14a) for 
the solvent and an outlet (18) for the dosing liquid. This is achieved 
by virtue of the inlet being connected to a mouth (16) 
for receiving the solvent in free space, whereby the solvent can flow 
into and fill the lower chamber to a level where it 
permeates the screen to take-up the product thereabove, whereafter it 
flows back into the lower chamber to exit via the outlet 
as the dosing liquid.

Title: Liquid manure injector
IPC: A01C23/02
Filed: 1988-12-01
Abstract: Device for the injecting of liquid manure into the ground. A very narrow cut is made in the ground of for example grassland by vertically disposed pairs of blades (7). Directly at the contact point between the blades debouches a nozzle (13) that is connected to a reservoir for liquid manure. Thus achieved is that the liquid manure is introduced directly into the narrow cut in the ground, after which the cut is closed up again by a following furrow closer. This prevents environmentally damaging ammonia escaping from the liquid manure into the surrounding air.

Patent EP-0356924-A3 (EP)
IPC: B29C47/04
Filed: 1989-08-25
Abstract: In the manufacture of a paint-coated 
stretchable film which is useful as a covering for 
automobile panels and other articles, a stretchable 
carrier film is formed by extruding a thermoplastic 
polymer composition onto a heat resistant temporary 
carrier film. The extruded layer is coated with paint 
or other layers and dried initially at a moderate 
temperature and finally at a high temperature which 
exceeds the heat deformation temperature of the 
stretchable carrier film but not of the heat 
resistant temporary carrier film. This shortens 
drying time and/or reduces residual solvents in the 
dried layers. The temporary carrier film, which is 
later stripped away, resists deformation of the 
laminate as it is drawn under tensile stress through 
the coating and high temperature drying stages.

Title: Illumination system for an lcd display system
IPC: G02B27/28
Filed: 1989-12-20
Abstract: An illumination system for an LCD projection 
display system to increase the brightness of the 
system. The system includes a polarizing beam splitter 
(26) which splits a beam of light (24) from a light 
source (20) into two orthogonally polarized beams 
(28,30). The beam of the desired polarization direction 
(28) is directed through a first face (A) of a prism 
(10) so that it reflects off of a second face (B) 
of the prism and exists through a third face (C) . 
The other beam (30) of the non-desired polarization 
direction is passed through a device (36) for 
rotating its polarization 90° and towards the underside 
of the second face (B) of the prism (10) at an angle 
such that it is refracted into the prism. Both beams 
(28,30) then exit the prism (10) through its third 
face (C) , have the same polarization direction, and 
are only slightly divergent. The recombined beam may 
be thereafter directed towards the light modulation 
system. The illumination system minimizes the number 
of air-glass interfaces and the number of reflecting 
surfaces.
