Publication number: 20080145626Abstract: Various embodiments of the present application relate to new form constructions and methods of forming and using the new form constructions. One method of printing a form construction involves (1) providing a substrate having a first major surface and a second major surface; (2) bossing at least a portion of the substrate to form a bossed substrate portion; and (3) attaching a signage to the bossed substrate portion. The signage or a printable portion of the substrate may then optionally be printed. An exemplary new form construction includes a substrate having a bossed substrate portion and an unbossed substrate portion; and a signage adjacent to the bossed substrate portion.Type: ApplicationFiled: December 15, 2006Publication date: June 19, 2008Inventors: Scott T. Ginkel, Sundar J. Rajan

Patent number: 4547603Abstract: Synthesis of methylcyclopentadiene with limited amounts of dimethylcyclopentadiene by-product. Cyclopentadiene monomer is complexed with metallic sodium in diglyme (diethylene glycol dimethylether) and reacted with an alkylating agent such as methyl chloride in the presence of a large stoichiometric excess of cyclopentadiene monomer. A high yield of methylcyclopentadiene is obtained with only a small production of undesirable methylcyclopentadiene. The excess cyclopentadiene is easily recycled in a continuous process.Type: GrantFiled: April 23, 1982Date of Patent: October 15, 1985Assignee: Ethyl CorporationInventor: Sundar J. Rajan

Patent number: 4467106Abstract: A process for making polyether/polyester glycols and the products formed thereby. Polyether/polyester glycols having a molecular weight of about 200 to 2,200 are formed by heating any of various glycols at about 150.degree. to 250.degree. C. under carbon monoxide pressure in the presence of a halide promoter. Preferably, iodide or bromide and a transition metal-containing catalyst are used to produce polyether/polyester glycols having a molecular weight in the range of 900 to 1,200.Type: GrantFiled: April 15, 1982Date of Patent: August 21, 1984Assignee: Ethyl CorporationInventors: Sundar J.

Patent number: 4456745Abstract: A process for the production of a polycarbonate glycol wherein a cyclic carbonate is catalyzed at elevated temperature by a cationic initiator. Compounds of structure (I) ##STR1## where R is alkylene, R' and R" are independently hydrogen, alkyl, alkaryl, aralkyl, or aryl, are heated at an elevated temperature in the presence of cationic initiators such as trimethyl aluminum to form a polymer. Production of a glycol product is assured by subsequent heating at about 200.degree.-220.degree. C. to form a polymer containing carbonate units of ##STR2## and having hydroxy end units bonded to a carbon not part of a carbonate function. The molecular weight of polycarbonate glycol is preferably at least about 1,000. Valuable new prepolymer mixes and polyurethanes may be prepared using the novel polycarbonate glycols of the invention.Type: GrantFiled: July 11, 1983Date of Patent: June 26, 1984Assignee: Ethyl CorporationInventor: Sundar J.
