Patent EP-0309858-A1 (EP)
Inventor: PLATTE HANS JOACHIM DR-ING
IPC: H04N5/783
Filed: 1988-09-20
Abstract: In a time-compressed reproduction of pictures recorded on magnetic tape, only individual pictures from a continuous picture signal are reproduced. Until a second picture following a first picture is found, read and reproduced, the first picture is repeatedly reproduced. This leads to unpleasantly jolting motion sequences. This impression is avoided by continuously cross-fading the successive pictures to be reproduced. The invention is applied in picture recording and reproducing devices.

Abstract: A process for the consolidation of discrete, particulate, low-melting or liquid materials, characterized in that said materials are consolidated in their particulate discrete form by application of vapours of at least one p-xylylene monomer and/or of a derivative thereof, which is polymerized under vacuum. 
     By such way, the materials are given the surface characte­ristics of a solid, with enhanced requisites of mechanical, physical and/or chemical strength, also in the presence of high temperatures. The invention is applied in particular in case of the metered and aimed addition to compositions, or in moving mechanical parts and so forth.

Abstract: For the preparation of titanium dioxide by the sulphate process, titanium slag and ilmenite are used as starting materials and are digested simultaneously but separately, i.e. different amounts of 98.5% strength and 85% strength sulphuric acid are added to them, the temperatures being slightly below the starting temperatures and the digestion reactions being initiated by adding a small amount of superheated steam. After the digestion, the two mother liquors are mixed and are processed together to give TiO2, the 23% strength dilute sulphuric acid obtained in the process being concentrated to about 85% with isolation of metal salts and being recycled. Highly concentrated sulphuric acid, preferably obtained by roasting the metal sulphates obtained in the process, is predominantly used for the titanium slag digestion, while the excess concentrated 85% strength sulphuric acid is used predominantly for the ilmenite digestion, so that the dilute sulphuric acid obtained can be virtually completely reused in an economical manner.

Title: Automotive instrument virtual image display
Inventor: HEGG RONALD G
IPC: G02B27/00
Filed: 1988-09-06
Abstract: A compact, inexpensive and mass-­
producible optical display system for an 
automobile creates a highly visible and 
sharp, high contrast and pleasing, multi-­
color magnified virtual image of a primary 
instrument cluster at a viewing distance 
which is greater than the actual optical 
distance between the dashboard and the 
driver's eyes in order to enhance instru­
ment readability, minimize driver eye 
strain, and reduce eye focus problems 
which are associated with transitioning be­
tween the far ranges viewing used for 
watching the road ahead and the near 
range viewing used for glancing at the in­
struments. A non-pupil forming display 
system uses a single off-axis asphericle 
mirror with power to create a virtual image of a miniaturized, multi-color passive image source, such as segmented LCD 
panel, which is backlighted by a small filament incandescent light bulb. The aspheric surface is optimized to minimize 
aberrations and reduce vertical disparity and field curvature. The image source is pre-distorted to compensate for distor­
tion in the off-axis configuration. A holographic diffusing screen element laminated onto the image source provides un­
iform high brightness and uniform contrast over the entire field-of-view which is visible from an eyellipse sufficient to ac­
commodate most of the driver population, minimizes the visual impact of any optical aberrations near the edge of the 
viewing area, and provides the non-pupil forming system with some of the desirable optical properties of a pupil forming 
system. The incandescent bulb is positioned at a remote location selected to minimize heat in the region of the image 
source and to facilitate replacement of the bulb in case of failure. The light emitted by the bulb is collected and focused in­
to the aperture of a fiber optic bundle which splits into a number of ends behind the LCD panel. Ambient reflections are 
reduced and controlled by a curved and tilted glare shield and a black surface light trap.
