  • Patent number: 5281630
    Abstract: A sulfonated water-soluble or water-dispersible polyester resin composition comprises a prepolymer resin, which prepolymer resin is further reacted with about 0.10 mol to about 0.50 mol of an alpha, beta-ethylenically unsaturated dicarboxylic acid per 100 g of prepolymer resin and a thus-produced resin, terminated by a residue of an alpha,beta-ethylenically unsaturated dicarboxylic acid, is reacted with about 0.5 mol to about 1.5 mol of a sulfite per mol of alpha,beta-ethylenically unsaturated dicarboxylic acid residue to produce a sulfonate-terminated resin. The prepolymer resin is (a) a reaction product of 20-50% by weight of terephthalate polymer, 10-40% by weight of at least one glycol and 5-25% by weight of at least one oxyalkylated polyol, preferably also comprising 20-50% by weight of isophthalic acid or (b) a reaction product of 20-50% by weight of terephthalate polymer, 10-50% by weight of at least one glycol and 20-50% by weight of isophthalic acid.

  • Patent number: 5089805
    Abstract: A vehicle deceleration indicator device which operates with the braking system of the vehicle. The device includes an array of lights (A), inertia switch apparatus (32, 34, 36, 38) and interconnecting circuitry. The switch apparatus are mounted on a swingable arm (24) which at all times remains at true vertical. Arm brake apparatus (D) are actuated when the vehicle is braked to secure the arm at true vertical and inertia acts against the switch apparatus to sequentially activate the lights (54, 56, 58, 60, 62) of the array.

  • Patent number: 4977191
    Abstract: A water-soluble or water-dispersible polyester resin composition, suitable for textile sizing applications, comprises a reaction product of 20-50% by weight of waste terephthalate polymer, 10-40% by weight of at least one glycol and 5-25% by weight of at least one oxyalkylated polyol. Preferred compositions also comprise 20-50% by weight of isophthalic acid. A further water-soluble or water-dispersible resin comprises a reaction product of 20-50% by weight of waste terephthalate polymer, 10-50% by weight of at least one glycol and 20-50% by weight of isophthalic acid.
