Patent EP-0364740-A3 (EP)
IPC: G03F7/40
Filed: 1989-09-16
Abstract: The structure comprises a pattern of a cured polymeric 
material deposited onto a substrate, said polymeric 
material having at least one fluorine-containing 
functional group and of an overlying silylated photo­
resist material.  
     For forming a structure on a substrate utilizing 
photolithographic techniques a layer of polymeric 
material containing a fluorine-containing compound is 
applied over the substrate and cured. A layer of photo­
resist material is applied over the polymeric material, 
imagewise exposed and developed to reveal the image on 
the underlying polymeric material. Thereafter, the 
photoresist is silylated, and the then present structure 
is reactive ion etched to transfer the pattern down to 
the underlying substrate. The fluorine component 
provides that the structure or the pattern and the 
underlying substrate respectively are free of residue 
and cracking.

Title: Improvements in or relating to fascia panel structures
IPC: E04D13/15
Filed: 1989-06-13
Abstract: The invention provides a new fascia panel 
structure consisting of a plurality of butting panels (22) 
disposed side-by-side on a support structure (18,20) fastened to 
the building to which the fascia is applied. The support 
structure (18,20) consists of two vertically-spaced horizontal 
parallel rails having upwardly opening channels. The 
panels (22) each have downwardly extending horizontal top and 
bottom edges which engage in the channels and can slide 
sideways therein. Each panel has a channel-forming 
member fastened to its rear surface adjacent one vertical 
edge, and a tongue-forming member (36) fastened to the rear 
surface adjacent the other vertical edge; these can also 
act as stiffening members. The panels are installed on 
the horizontal rails (18,20) and slid sideways until the 
respective panel tongue is engaged in the adjacent panel 
channel, the tongue covering any wall gap that may be 
left to accomodate expansion. The panels are held in 
place by an elongated horizontal hold-down cap strip (28) that 
is fastened to the building and engages their top edges. 
The panels are therefore "free-floating" on their support 
structure to avoid distortion with changes in ambient 
temperature, and consequent buckling and "oil-canning". 
The preferred material for the panels (22) is sheet aluminum, 
or its alloys, and preferably the other members are of 
extruded aluminum, or its alloys. Preferably the members 
are fastened to the rear face of the panels by glueing, 
using double-sided adhesive tape.

Filed: 1990-03-29
Abstract: An aircraft on-board oxygen generation system having control means 
14 for cycling sieve beds of a molecular sieve-type gas separation 
system 10, provides product gas having a partial pressure of oxygen 
that more closely approaches the ideal value at any cabin altitude

levels within the operating range and displays desired product gas 
oxygen content at altitudes sensed by altitude sensor means 17 for 
comparison with delivered product gas oxygen content sensed by oxygen 
content sensor means 19. The control means provides for a range of 
selectable cycle time and adjusts the cycle time in the sense required 
to null the difference between displayed and sensed oxygen content of

Patent EP-0404587-A3 (EP)
Title: Optical fiber coupler and a fabrication method for the same
IPC: G02B6/28
Filed: 1990-06-22
Abstract: The present invention provides a wide wavelength range 
optical fiber coupler that to the greatest extent possible, 
allows optical coupling which is wavelength independent, and 
thus demonstrates a constant coupling ratio over a wide range 
of wavelengths. By causing various irregularities (17) to be 
formed in the fused-elongated region of an optical fiber 
coupler (16), thereby leading to the generation of additional 
modes in addition to the fundamental modes, while at the same 
time causing multiple mode coupling in which the above 
mentioned additional modes participate in the coupling of the 
fundamental modes, it is possible to selectively control the 
coupling strength at determined wavelengths and thereby 
achieve optical coupling which is largely wavelength 
independent and thus demonstrates a relatively constant 
coupling ratio over a wide range of wavelengths. 
Furthermore, by causing the strength of coupling between the 
cores of each component optical fiber to vary along the 
length of the longitudinal axis of each component optical 
fiber, it is possible to decrease the degree of sinusoidal 
variation in the wavelength dependance characteristics of 
each component optical fiber, thereby making it possible to 
further achieve optical coupling which is wavelength 
independent and thus considerably constant over a wide range 
of wavelengths.
Patent EP-0399978-A3 (EP)
Title: Method and apparatus for overwriting data on a magneto-optic disk
IPC: G11B11/105
Filed: 1990-05-21
Abstract: Direct overwriting of encoded data along a track in a 
magneto-optic recording medium (10) is described. A laser 
(24) beam, not modulated by data, is directed at the active 
side of the medium to locally heat the width of one track for 
conditioning it for direct overwriting. A magnetic head (30) 
comprising an inductor and a capacitance in parallel with the 
inductor is movable in an appropriate manner to a selectable 
track. While the head is in alignment with the beam, current 
of a preselected polarity is supplied from a current source to 
the inductor. The current source is disconnected to reverse 
the field of the magnetic head by reciprocation of energy 
between the inductor and capacitance. Once the magnetic field 
is reversed, current is supplied to the inductor for maintaining 
the field until the next field reversal, the reversal 
times being determined by the data to be written.  
     For pulse width modulation recording, the current normally 
supplied to the inductor is of one polarity and that 
supplied following the reversal is of opposite polarity; 
whereas for pulse position modulation recording, the current 
supplied to the inductor is of the same polarity before and 
after reversal.  
     The inductor is preferably mounted for movement on a 
voice coil actuator and thereby maintained at a predetermined 
fixed distance from the medium.

Title: Process for applying powder coatings to metallic surfaces
Inventor: BOHNACKER ULRICH
IPC: B05D1/14
Filed: 1991-09-13
Abstract: In electrostatic powder coating, the starting materials used are metal surfaces which are furnished with an oil film for protection against corrosion during storage and transport. The polymer powder is applied to the surface without removing the oil film. The powder layer is then melted in an oven and is finally cured by cooling. The heat applied by the oven should be sufficient to volatilise the oil. An oil is preferably used which remains stable or resistant during the heating process as long as it remains on the workpiece surface. This includes the possibility that individual components or the entire oil diffuse through the powder layer and evaporate during the heating-up process, or alternatively that part or all of the oil quantity remains on the workpiece during the heating process and mixes with the powder layer. In both cases, the quality of the plastic coating is not adversely affected by the oil film.
