Title: Flash spinning process for forming strong discontinuous fibres
Inventor: CLOUTIER SYLVIE
IPC: D01D5/11
Filed: 1993-11-05
Abstract: A continuous process for the manufacture of strong discontinuous fibres from a polyolefin is disclosed. The process comprises feeding a solution of polyolefin dissolved in an organic solvent at a pressure that is at least autogenous pressure to a spinneret.      Plexifilamentary film-fibril strands are formed by flash spinning, by passing said solution through the exit of the spinneret and into a tunnel at a lower pressure and temperature than the solution, the temperature being greater than the boiling point of the organic solvent.      At or subsequent to the exit from the spinneret but inside the tunnel, the strands and solvent are contacted in the tunnel with an inert fluid that has a liquid and a vapour phase, the amount of inert fluid being such that the ratio of the total volumetric flow rate of solvent vapour plus inert fluid vapour to the mass flow rate of the polymer is greater than 4.5 m3/kg in the tunnel. The temperature of the inert fluid in the tunnel is 2-40°C lower than the melting point of the polymer. Strong discontinuous fibres are recovered. The fibres, especially in the form of a pulp, may be used as part of thermally bonded blends with cellulose, as a filler and in the form of sheet.

Title: Homeotropically oriented liquid crystalline polymer film comprising dichroic dye
Inventor: PICKEN STEPHEN J
IPC: G11B7/0055
Filed: 1994-01-24
Abstract: ABSTRACT            The   invention   pertains  to   a   homeotropically  oriented ? liquidcrystalline polymer film comprising at least one dichroic dye. This homeotropic orientation along with the presence of dichroic dye makes it  possible  to  employ  a  different  technique  for writing  out  and reading data.            For, in this case contrast is obtained by the dichroic dye contained in the film being aligned  in the same direction as the mesogenic groups  of  the  liquid  crystalline  polymer.  In  a  virgin  film  the mesogenic groups, and hence the dichroic dye molecules, are oriented perpendicular to the film's surface, and there is only low absorption of  the  incident  light  by  these  molecules.  By  local  heating  or irradiation  of  the  film  (e.g.,  with  a  laser)  the  homeotropic orientation  is  converted to  an  isotropic  one.  In  the  case  of  an isotropically  written  trace, the  dichroic  dye  will  likewise  be isotropically oriented, resulting in a substantially higher absorption of the incident light.            The films according to the invention are suitable for use in analogue and digital  optical  data storage,  as well  as,  of course,  combined analogue/digital data storage.

Title: Method for the preparation of an olefin polymerization catalyst consisting of particles of equal size
Inventor: GAROFF THOMAS
IPC: C08F4/65
Filed: 1992-11-27
Abstract: In the invention a particular procatalyst composition intended for the polymerization of olefins is prepared by reacting the carrier particles consisting of a MgCl2-C2H5OH-complex with TiCl4. When the method is applied into pilot-scale it was noticed that the procatalyst composition obtained produced olefin polymer, the finely-divided material portion of which was deterioratingly high. This was caused by the fact that the procatalyst composition particles had decomposed to finely-divided material during the synthesis, which was then in the polymerization repeated in the polymer structure due to the so-called replica phenomenon. In the invention it has unexpectedly been noticed that the breaking of the carrier particles is not a result of e.g. mechanical strain but of the fact that when the carrier particles react with the TiCl4 a heavy discharge of hydrogen chloride is first occurring as a result of the reaction which breaks the carrier particles. The carrier particles can, according to the invention, be maintained undamaged during the reaction by distributing the release in the reaction or from the reaction of the hydrogen chloride created in the reaction to a molar velocity not exceeding the fivefold value of the molar mean velocity of the release. This is achieved among other things by adding reagents unusually slowly, by using lower temperatures and heating velocities, by intensifying the agitation, by using an overpressure and/or by conducting diluting inert gas into the reaction mixture.

Title: Protective Tunable Circuit for Electro-Mechanical Equipment
Inventor: HUGHES RICKEY D
IPC: F16P3/14
Filed: 1991-12-16
Abstract: A circuit for controlling and stopping the motion of dangerous moving parts is disclosed.  The circuit includes an antenna (16) connected to a moving part (18) and coupled to a tunable circuit (10) for controlling a safety equipment (32). The antenna (16) provides a variable lumped capacitance parameter within the tunable circuit (10). This lumped capacitance parameter is variable in response to an operator's body capacitance produced when the operator comes within a predetermined critical proximity to the moving part (18).  This variation in lumped capacitance serves to tune the circuit (10) at or near a point of resonance to thereby enable an RF signal to pass through the tunable circuit (10) at a detectable level which is subsequently processed to activate the safety equipment (32) for controlling and stopping the motion of the moving part (18) substantially instantaneously.

Abstract: A modulator (10) for modulating incident rays of light, the modulator having several equally spaced beam elements (18), each having a light reflective planar surface. The beam elements are arranged and supported (12) parallel to each other, with their reflective surfaces parallel. During operation, the elements remain parallel, but the modulator moves the beams so that the per-pendicular spacing of their reflective surfaces changes between two configurations. In both configurations, the spacing equals m/4 times the wavelength of incident light. In the first configuration, m equals an even whole number or zero, and the modulator acts to reflect the incident rays of light as a plane mirror. In the second configuration, m equals an odd number and the modula-tor diffracts the incident rays as they are reflected.
