Abstract: In a cover (1) for overhead transparencies (not shown) and con­
sisting of a pocket (2) with ring file holes (9) and a non-­
transparent mask flap (3) to cover the part of the light plate 
of the projector which is not covered by the pocket (2), the 
novelty is that the mask flap (3) is hinged to the pocket (2) at 
the edge which is opposite the edge with the ring file holes 
(9).  
     This provides a plurality of advantages, e.g.  
- that the cover is easy to manufacture and therefore inex­
pensive, and  
- that the opposite side of the mask flap may be used as an 
index leaf for the cover when it is placed by means of the 
holes (9) in a ring file (not shown) together with several 
other covers of the same type.
Patent EP-0347895-A3 (EP)
IPC: C08G77/34
Filed: 1989-06-22
Abstract: This invention provides a platinum-containing 
hydrosilylation catalyst in particulate form with an 
average particle size not exceeding 100 micrometers. The 
particles also contain a silicone resin having a 
softening point of from 50 to 200 degrees Centigrade. 
The improvement resides in the presence of a surface 
layer in said particles that is essentially free of the 
platinum-containing catalyst. As a consequence of this 
structure, when the catalyst composition is used as the 
curing catalyst in a hydrosilylation-curing 
organopolysiloxane composition, the composition 
characteristically exhibits an excellent storage 
stability while still curing rapidly upon heating.

texture thereon. Adhesion between the polynorbornene 
prepreg and the conductive surface is improved by 
coating the conducting surface with as silane 
coupling agent and/or by providing polyolefin film 
therebetween. To improve or reduce the dielectric 
constant, polyolefin powder can be placed in the 
dipping bath in the preparation of polynorbornene 
prepregs. Epoxy prepreg can also be incorporated 
into the laminates. Multi-layer laminates can be 
provided of alternating or non-alternating epoxy 
prepregs and polynorbornene prepregs. The prepregs 
are made by a process which includes an adhesion 
promotion step wherein the prepreg, preferably 
polynorbornene prepreg, prior to lamination, is 
pretreated with a silane adhesion promotion agent. 
One or more copper foils can also be employed between 
exterior surfaces of the prepregs, at the interface 
between the prepregs, as well as on the exterior of 
the laminates. The copper films can be etched to 
form patterns such as those suitable for printed 
circuit wiring boards.

Abstract: The present invention relates to a method for monitoring the 
viscosity of a fluid, which method is  characterised in that:  
   a. the fluid is passed through a device comprising two 
non-identical flow restrictors connected in series, in which 
device the variation in the flow of fluid through one of the 
restrictors under the conditions of operation of the device 
with respect to a change in viscosity of the fluid is 
different to the variation of flow through the other 
restrictor for the same change in viscosity of the fluid 
flowing therethrough; and    b. the pressure in the fluid between the restrictors 
relative to the pressure drop across the device is monitored 
to give an indication of a change in the viscosity of the 
fluid flowing through the device.     
     The invention also provides a device for monitoring 
viscosity having two non-identical flow restrictors in 
series and means for measuring the pressure in the fluid 
between the restrictors.

Title: A method for neutralizing sulfuric acid containing zinc ion
IPC: C22B3/26
Filed: 1989-08-16
Abstract: The invention relates to a method for neutralizing 
a sulfuric acid solution containing predominantly Zn 
ion. In the method of the invention at least one 
compound selected from chlorine-containing compounds of 
Na ion, K ion, Mg ion, Ca ion, and NH₄ ion in an amount 
at least chemically equivalent to SO₄ ion contained in

selected from oxygen-containing organic solvents and 
alkylamine organic solvents to extract Zn ion from the 
sulfuric acid solution as a chloride complex to the 
organic solvent. The sulfuric acid solution after 
extraction of Zn ion may be further treated by addition 
of an oxidizing agent or by an electrochemical means to 
convert Fe²⁺ into Fe³⁺ ion and brought into contact with 
a second organic solvent (B) composed of one or more 
species selected from oxygen-containing organic solvents 
and alkylamine organic solvents. In that manner Fe ion 
is extracted from the sulfuric acid solution as a second 
chloride complex to the second organic solvent (B).

Title: Enhanced resolution electrophotographic-type imaging station
IPC: H04N1/06
Filed: 1989-12-07
Abstract: An electrophotographic-type imaging station or 
printer includes a focusing lens positioned between the 
printer light source and a photosensitive medium. As the 
light source projects beams of light energy forming a row 
in a direction towards the photosensitive medium, the lens 
focuses each projected beam into a rectangular beam. The 
speed of the photosensitive medium and the operation of the 
light source are coordinated so that adjacent rows of 
generally rectangular beams are positioned in abutting 
relation with each other. The plurality of focused rows 
projected in row-at-a-time fashion onto the surface of the 
photosensitive medium form an informational array pattern 
having a resolution in a direction parallel with the 
direction of medium movement which is greater than the 
resolution of the pattern in a direction perpendicular to 
the direction of medium movement. By forming an 
informational array pattern in this manner, a desired 
informational array pattern gray scale may be achieved 
without a loss in the original resolution of the array 
pattern taken in a direction perpendicular to the direction 
of medium movement.
