  • Publication number: 20230044738
    Abstract: The present invention relates to a collar for non-human animals, preferably for companion animals, comprising a polymeric matrix and a lipid extract comprising sphingomyelins. It also refers to the collar for use as a medicine, particularly for use as an adjuvant and for use in the treatment or prevention of atopic dermatitis or allergic dermatitis, as well as in restoring the integrity of the skin during or after an atopic dermatitis or an allergic dermatitis, increasing the hydration and flexibility of the skin, facilitating skin regeneration or reducing itching of the skin.

  • Patent number: 5096282
    Abstract: A method of forming a polymer dispersed liquid crystal (PDLC) film is disclosed which consists of forming a solution of LC dissolved in a monomer, photopolymerizing the solution to form a film having a dispersion of LC bubbles therein, establishing a correlation between the LC bubble size and selected characteristics of the film, selecting a LC bubble size corresponding to desired film characteristics, and controlling the conditions of photopolymerization to achieve said LC bubble size. The LC bubble size is controlled by means of the UV exposure intensity, exposure temperature, exposure wavelength, LC concentration and/or concentration of polymerization initiator. Correlations are noted between LC bubble size and the resulting film's threshold and operating voltages for optical transmission, contrast ratio, absolute transmissivity and electro-optical response times.

  • Patent number: 4944576
    Abstract: A polymer dispersed liquid crystal (PDLC) film, along with various fabrication methods that enable partial prealignment of the film's LC bubbles, are described. The film is formed with a matrix of liquid crystal bubbles. Individual liquid crystals within the bubbles are partially, but substantially less than fully, aligned in a given direction. Partial alignment is attained by the controlled application of an electric or magnetic field, or a mechanical flow, during photopolymerization. The resulting films retain the positive qualities of prior PDLCs, and in addition exhibit generally lower threshold and operating voltages, and can be used as tunable birefringent films in the infrared region.
