Patent EP-0989827-A1 (EP)
Inventor: FISCHER DAN E
IPC: A61K8/00
Filed: 1997-10-10
Abstract: Dental bleaching compositions are made with a bleaching agent and a stable radiant-energy absorbing compound that acts as a bleaching agent activator. The dental bleaching compositions of the present invention can be one-part, pre-mixed compositions that do not require mixing at the time of treating a patient's teeth but which remain stable over time. The bleaching agent may consist of hydrogen peroxide, either in aqueous form or complexed with urea (carbamide peroxide) or sodium perborate. The bleaching agent activator includes hydrocarbons that are stable in the presence of the bleaching agent, which do not prematurely accelerate liberation of the bleaching agent, but which allow for selective activation of the bleaching agent by irradiation of the bleaching composition with radiant energy. The bleaching composition may optionally include a neutralizing agent to adjust the pH, a carrier to help provide proper consistency and potency, and a stabilizing agent to maintain maximum potency of the bleaching agent over time. The bleaching composition may also include a thickening agent to achieve a selected viscosity. The dental bleaching compositions may be adapted to be loaded into and delivered from a syringe.

Abstract: A method for forming ceramic tiles, including those of large
dimensions, by means of partially isostatic moulds, comprising the
following stages: loading the powder to be pressed into the mould
cavity; exerting a uniform pressure on the entire surface of the
powder present in the mould cavity; releasing the pressure and
partially opening the mould to facilitate powder deaeration;
exerting pressure on a first portion of the surface of the powder
contained in the mould cavity; exerting pressure on a second
portion of the surface of the powder contained in the mould
cavity, with simultaneous nullification of the pressure on said
first surface portion of the powder contained in the mould cavity;
alternating the exertion of pressure on said first and on said
second portion alternately. The press for implementing the method
is characterised in that the punch (5) comprises a cavity (51), a
lattice (52) positioned within said cavity and defining a plurality of
cells (53), an elastic membrane (54) securely fixed to the edges of said
cavity (51) and of said lattice, the cells (53) being connected to a
pressurized oil source via a distributor valve (15) arranged to connect
the cavity (51) alternately to said source and to discharge. The

Abstract: The present invention relates generally to the field phase detectors
and particularly to a phase detector being formed by a flip-flop. 
     Phase detectors being formed by a flip-flop are known. However, for
the realisation of the known phase detectors several parameters have to
be dimensioned individually in order to achieve an optimised phase
detector. 
     With the present invention it is no longer necessary to explicitly
dimension these parameters. The phase detector has a D-flip-flop (2)
with a first output (Q) for generating a control signal (OUT), a first
input (C) for a feedback clock, a second input (R) for a pulse (RES)
generated from a reference clock (REF), and a third input (D) to which
the complemented first output (Q') is coupled and a gate (4,2) for
generating the pulse (RES) from the reference clock (REF), whereby an
output of the gate (4,2) is coupled back to an input of the gate (4,2).
In embodiments, the gate in either formed by an additional D-flip-flop
(4) or by an AND-gate (4) and the phase detector D-flip-flop (2).
Furthermore additional gates (A1,A2,A3,5) may be provided to minimise
the skew of the phase detector.

Abstract: A reconstructing process is described
for a secondary differential value image, being
capable of correcting blurring at the contour portion of
an original image to form an image having a sharp contour,
an image contour emphasizing process method based on the
reconstructing process method, and a thermal transfer
printer for performing recording based on the contour
emphasizing process method. 
     For this purpose, the primary differential value and
the second differential value of each pixel of an original
image are calculated, the original image is scanned in
horizontal and vertical directions to detect a contour
line on the basis of the signs of the primary differential
value and the secondary differential value, a secondary
differential value at a position shifted from the interest
pixel by an arbitrary width is substituted as a secondary
differential value located at the interest pixel to
reconstruct the secondary differential value image.

Abstract: A method for preventing the deposition of
material in an opening (18) near a surface of an article,
and a masking insert (20) therefore. The method and
insert are particularly suited for preventing the plating
of a metal, such as platinum, on turbine airfoils or
turbine blades and vanes having a complex geometry, as
is the case when cast trailing edge cooling slots are
present in the airfoil surface. The method entails the
use of the masking insert, which is precisely configured
to mask the cooling slots (18) during plating by
preventing circulation of the plating bath through the
slots. For this purpose, the insert is equipped with
appendages (24) that are sized, shaped, spaced and
oriented on a base member (22) to register with, and
preferably be received within, the cooling slots of an
airfoil (12) having a particular cooling slot design.

Abstract: L'invention concerne un procédé et une composition permettant de modifier une séquence plausible d'événements pathologiques se produisant dans des cellules ganglionnaires de la rétine, associée au glaucome. Cette séquence comprend une dépolarisation de membranes, une apport de quantités millimolaires de Na+ via des canaux de Na+ non inactivants, et l'élévation létale de cellules Ca2+ due à l'inversion de l'échangeur de Na+/Ca2+. Le procédé comporte l'étape consistant à bloquer, par l'administration d'une composition sélectionnée, des canaux Na+ associés non inactivants situés dans des cellules ganglionnaires de la rétine, afin de limiter l'échange de Na+/Ca2+ dans les cellules ganglionnaires de la rétine, et d'empêcher que l'accumulation de Ca2+ dans les cellules ganglionnaires de la rétine n'atteigne un taux létal.

for purifying an exhaust gas, a loading layer comprising mordenite is loaded with
alumina sulfate and cerium sulfate-zirconium composite oxide, and Pt is loaded on
these. And, in a temperature range where HC are not oxidized, the HC are
adsorbed and held by the mordenite the HC, which the mordenite releases at the
temperature increment, are subjected to cracking by the mordenite, the alumina
sulfate and the cerium sulfate-zirconium composite oxide, and the thus produced
low-grade HC are turned into reducing agents, thereby reducing and purifying the
NO x  in the exhaust gas.
