Patent number: 5799377Abstract: A balloon decoration enclosure apparatus includes a generally flat closure disk having first, second and third spaced-apart slots, each extending from the perimeter of the disk toward the center thereof, to allow threading the neck of an inflated balloon up through the first slot, over the top of the disk and down through a second slot, and then under the disk and up through the third slot. When so positioned, the inflated balloon extends downwardly of the disk, and the mouth of the balloon extends upwardly a short distance. The disk includes a nipple extending upwardly from near the center of the disk for insertion into a centrally disposed opening of a retainer disk which is pressed down upon the closure disk. A decorative sheet of resilient material is disposed between the closure disk and retainer disk when the retainer disk is in place on the closure disk, so that the material extends upwardly and outwardly from the closure disk and retainer disk in a decorative, generally conical shape.Type: GrantFiled: November 12, 1996Date of Patent: September 1, 1998Assignee: Maxim, Inc.Inventors: William G. Carroll, James R. Cook

Patent number: 5477664Abstract: Apparatus for inflating balloons to enable insertion thereinto of objects includes a loading ring insertable into the orifice or mouth of the balloon for stretching the orifice to allow insertion therethrough of an object into the interior of the balloon when inflated, and a balloon inflating housing for accommodating an inflated balloon. The housing includes upper and lower hemispherical shells which may be sealingly fitted together to form a complete spherical shell and to allow inflation of the balloon therewithin, and then separated to allow removal of the inflated balloon.Type: GrantFiled: August 11, 1994Date of Patent: December 26, 1995Assignee: Maxim, Inc.Inventor: William G. Carroll

Patent number: 5366192Abstract: A stand for holding a message or felicitation card vial and flower includes a generally planar base having a front edge and an upright plate extending upwardly from the front edge of the base, and having a top edge and a front face which faces forwardly of the front edge of the base, where the upright plate includes tabs for holding the card flat against the front face of the plate. Extending rearwardly of the top edge of the upright plate is an annulus which defines a circular opening, and on which is mounted a sleeve extending vertically upwardly from about the opening, directly above the base. A vial having an open upper end and a closed lower end is provided for disposition in the sleeve so that the closed lower end rests on the base and the open upper end is directed upwardly to receive and hold the stem of a flower.Type: GrantFiled: October 8, 1992Date of Patent: November 22, 1994Assignee: Maxim, Inc.Inventor: William G. Carroll

Patent number: 4758606Abstract: A polyester polyol derived from a polyalkoxylated by-product of pentaerythritol manufacture and polycarboxylic acids, the latter being themselves by-products from the production of adipic acid or terephthalic acid or derivatives thereof, useful for the manufacture of rigid foam.Type: GrantFiled: January 24, 1986Date of Patent: July 19, 1988Assignee: Imperial Chemical Industries PLCInventors: James M. Bentley, James P. Brown, William G. Carroll
-
Patent number: 4590226Abstract: A polyether polyol having an average hydroxyl value in the range 400 to 650 mgKOH/g which is a alkoxylated derivative of a polyhydric alcohol being itself a single compound or a mixture of compounds according to the general formula (I) ##STR1## where R.sup.1 is --H, --CH.sub.3 or OCH.sub.3R.sup.2 is --H, --CH.sub.2 OH or --CH.sub.2 C(CH.sub.2 OH).sub.3The preparation of polyurethanes, including rigid foams, using these polyols, is also disclosed.Type: GrantFiled: January 29, 1985Date of Patent: May 20, 1986Assignee: Imperial Chemical Industries Inc.Inventors: James P. Brown, William G. Carroll, Ronald N. May, Erik M. B. Merckx, David J. Sparrow

Patent number: 4576974Abstract: A mixture of polyols useful in preparing closed cell rigid foams. The polyols are made by blending a polyester polyol derived from succinic, glutaric and adipic acids and a non-polymeric or polyoxyalkylene polyol having a functionality from 3 to 4. When reacted with an organic polyisocyanates, the resulting rigid polyurethane foams are dimensionally stable and less flammable compared with polyether-based products.Type: GrantFiled: February 11, 1985Date of Patent: March 18, 1986Assignee: Imperial Chemical Industries, PLCInventors: William G. Carroll, Ian D. Rosbotham

Patent number: 4554306Abstract: Polymer-modified polyols of reduced viscosity are made by reacting an organic polyisocyanate with a low molecular weight hydroxyl-containing compound in a polyol in the presence of a specified dispersant. The dispersant, which is of a type known for dispersing pigments in paints, is obtained by reacting(1) a copolymer comprising units derived from the following ethylenically unsaturated monomers in the stated proportions by weight based on the total weight of the copolymer:(a) 0-50% of a hydroxy group-containing monomer, and/or(b) 0-20% of an amide group-containing monomer, provided that there is always present at least 5% of (a) and (b);(c) 20-80% of a monomer free from carboxyl groups and containing a straight or brancehd chain alkyl group of from 7 to 22 carbon atoms, and(d) 0-50% of one or more monomers free from the hydroxy, amide and C.sub.Type: GrantFiled: June 7, 1984Date of Patent: November 19, 1985Assignee: Imperial Chemical Industries PLCInventor: William G.
