Title: Liquid crystal temperature sensor and materials
Inventor: FERGASON JAMES L
IPC: G02F1/13
Filed: 1985-05-22
Granted: 1991-10-08
Abstract: ABSTRACT The present invention relates to liquid crystal temperature indicating compositions, preferably absent cholesteric liquid crystal material, and the containing of such compositions in volumes formed in a containment medium that tends to distort the liquid crystal structure when the temperature thereof is below a transition or clearing point temperature. The containment medium is water resistant, e.g. insoluble in water, and preferably has heat and optical stability, e.g. does not brown or otherwise discolor, at relatively high temperatures, e.g. above 100°C. Plural liquid crystal materials having different transition temperatures may be mixed to form a liquid crystal material having a transition temperatures intermediate those of the ingredients. In such distorted or curvilinearly aligned mesomorphic phase, the index of refraction of the liquid crystal is different, preferably greater, thanthat of the containment medium; therefore, incident light will be scattered, preferably isotropically, and such scattered light can be used as a tempera-ture identifier. However, above a transition temperature, the liquid crystal material changes to an isotropic phase, which is substantially optically transparent, on the one hand; and the liquid crystal is so selected such that in the isotropic phase it has an index of refraction substantially matching that of the containment medium. Incident light is transmitted by the isotropic liquid crystal and, accordingly, provides another temperature identifier. The scattering liquid crystal material will appear visually brighter than the transmitting liquid crystal material, especially when illumination is provided by light from a source independent of ambient light. Moreover, dye can be used to color the scattered light.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for securing one or more parts,  each of which is provided with an opening,  to a hollow member.   In the starting state,  the inner diameter of the opening of the parts is greater than the outer diameter of the surface provided on the hollow member for securing the part.  The parts are placed in the prescribed position on the hollow member prior to the securing operation.   In order in a simple and economical manner to reliably secure the parts to the hollow member without the danger of overstressing the latter, and without the danger that the parts will loosen, a temperature difference is produced, prior to placing the parts on the hollow member,  by heating the parts and/or by cooling the hollow member.  Subsequently, each part is secured to the hollow member by widening the latter at least in the securing regions thereof, and by a subsequent shrink fitting of the parts onto the hollow member as a consequence of the temperature equalization that occurs.

Abstract: ABSTRACT OF THE DISCLOSURE    A rechargeable organic electrolyte cell is disclosed which is superior in charge-discharge cycle characteristics.          The cell comprises an anode containing lithium, a cathode formed of LiMn2O4 and organic electrolyte.  The LiMn2O4 is preferably such material that has a full width at half maximum between 1.1 and 2.1° of a peak at 2.THETA.  equals to 46.1° by X ray diffraction analysis using FeK.alpha.  ray.

Abstract: ABSTRACT     Superabsorbent Flocks, Methods Suitable for their Production and Application The invention relates to superabsorbent fibre flocks comprising a core of absorptive polymer wherein short polymer fibres have been embedded, such short polymer fibres protruding at least partially from the  core.  Such superabsorbent fibre flocks can be produced by binding absorbent polymer particles to  each other  and to the polymer fibres  with the  said of  a bonding agent and by grinding the fibre flocks thus obtained to the required  particulate size.          The superabsorbent fibre flocks according to the invention can be used  to  advantage  in  sanitary  products,  especially  in baby diapers,  menstrual  pads  and  incontinence  articles  and  have further application in separating  water  and  aqueous components from hydrophobic liquids.

Abstract: TITLE OF THE INVENTION COLOURED HYDROGEL OBJECTS AND THEIR PRODUCTION     ABSTRACT OF THE DISCLOSURE          Shaped organic polymer hydrogels, especially contact lenses, are provided with opaque or translucent colouring so as to he capable of masking effectively any underlying colour, e.g. the natural colour of the eye.  The hydrogel may be rendered opaque by precipitation in situ of a white or yellow water-insoluble, inorganic material e.g. barium sulphate and then coloured with a suitable dyestuff.

Abstract: ABSTRACT OF THE DISCLOSURE     A plurality of magazines each of which contains a plurality of film sheets of a type different from those contained in the other magazines are accommodated in movable trays.  These movable with respect to the elevator trays are disposed within an elevator in such a manner as to be movable from a retracted position to a film unloading position.  Each of the movable trays has a hook.  When the elevator is moved to a desired position, an insert member such as a rod enters the hook located at that position so as to move the tray to the film unloading position at which the film sheet is taken out of the magazine.

Abstract: ABSTRACT     An insulated vacuum container comprising inner and outer wall sections, with each wall section made up of a skeletal frame, with membranes enclosing each frame.  The membranes of the outer wall section curve inwardly, while the membranes of the inner section curve outwardly.  The pressure loads imparted on the membranes are reacted substantially entirely in tension onto the skeletal frames.  There is a rear end wall, mounted so as to be movable longitudinally relative to the outer wall section so as to permit thermal contraction and expansion of the inner wall section relative to the outer wall section.
