Patent CA-2019225-A1 (CA)
Inventor: LESQUIR DOMINIQUE
IPC: B65D43/06
Filed: 1990-06-18
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to the combination of a closure and of a container, the closure displaying a peripheral depending skirt while the container displays, along the walls thereof, a continuous peripheral flange receiving, on the top face thereof, the lower edge of the closure skirt.   The connection of the flange at each corner is weakened by the presence of a series of gaps to render the flange at those areas breakable to thereby provide a visual indication of removal of the closure, whether it be authorized or unauthorized.

Title: Ferroelectric liquid crystal components having high spontaneous polarization and low helical pitch
Inventor: ESCHER CLAUS
IPC: C09K19/02
Filed: 1990-06-22
Abstract: Ferroelectric liquid crystal components having a high spontaneous polarization and a small helical pitch Liquid  crystal  materials  are  becoming increasingly important in  electro-optical  switching  and  display devices.  During  recent  times,  ferroelectric  liquid crystal  mixtures  have  also been investigated  to  a particularly great extent and used in displays.            A physical quantity which is particularly important for the purpose of describing FLC mixtures is the spontaneous polarization (Ps). On the one hand, a high spontaneous polarization leads to short switching times, while on the other hand in the case of high Ps values an optical hysteresis occurs, which leads, inter alia, to so-called "ghost images".            In spite of high spontaneous polarization, the problem of the optical hysteresis may be overcome by the use of FLC mixtures having a high spontaneous polarization (Ps 20 nC/cm2) and a natural helical pitch of less than one half of the layer thickness in an SSFLC display with a layer thickness of 1 to 10 µm.            FLC mixtures with Ps > 40 nC/cm2 can also be switched under these conditions.

Filed: 1991-05-17
Abstract: ABSTRACT OF THE DISCLOSURE An openable skylight assembly covers a roof opening having a raised curb around its perimeter that extends substan-tially perpendicularly from the roof surface.  The skylight includes glazing means that substantially covers the opening.  A frame assembly surrounds the glazing means, and has a depending skirt portion that opposes the outer surfaces of the curb.  A hinge, joining one side of the frame to the curb so that the skylight frame may be pivoted to open the skylight, includes a generally circular bearing that is received in a cradle, which is an integral part of the frame assembly that holds the glazing means.  The internal curved cradle surface has an arc exceeding 180° such that the bearing and cradle cannot be separated except when flat surfaces provided on the bearing align with the opening between the ends of the curved cradle surface.  Then, by transverse motion relative to the longitudinal axis of the hinge, the frame assembly separates from the curb.  No tools are required for removal and attachment of the movable skylight cover to the curb.

Filed: 1991-05-31
Abstract: ABSTRACT            PROCESS AND APPARATUS FOR THE CONTINUOUS DRYING OF WOOD SHAVINGS, WOOD FIBRES OR OTHER BULK MATERIALS            The invention relates to a process and an apparatus for the continuous drying of wood shavings, wood fibres or other bulk materials, in which the heat of combustion gases produced in a combustion chamber is utilized in a drier supplied with the material to be dried.            The inventive process is characterized in that the combustion gas-free vapours leaving the drier are recycled to the latter and upstream of the drier are indirectly heated by the combustion gases leaving the combustion chamber to the temperature necessary for drying the material to be dried and a partial vapour flow is branched off from this circuit and led to the combustion chamber.   In the apparatus for performing the process from the cyclone or cyclones (12) used for separating the drying material a pipe (13) for the vapours returns to the drier (8), that the pipe (13) contains a heat exchanger (7) for the indirect heating of the vapours by the combustion gases leaving the combustion chamber (1) and that a branch line (6) to the combustion chamber (1) branches off from the pipe (13) upstream of the heat exchanger (7) in the flow direction.   The invention makes it possible with limited expenditure to respect lower than prescribed pollutant emission limits, whilst increasing efficiency and decreasing the explosion risks.
