Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE A dual-purpose lottery play ticket and boarding pass issued by a commercial passenger carrier to each passenger boarding an aircraft for commercial flight.  The invention comprises two parts, the first part of which is to be retained by the air carrier upon boarding, while the second part of which is to be retained by each passenger.  Both first and second parts include data printed thereon describing each passenger by name and/or frequent flyer number, and information to finding a particular  schedule  flight designation.   Both  parts  also include identical lottery play indicia printed thereon so that each  passenger  has  the  opportunity  to  enter  a  lottery sponsored by the air carrier.   By each party retaining a properly validated part of the invention, proof of entry and selection are secured.  The preferred form of the invention envisions each passenger making a lottery number selection in conjunction with boarding the aircraft;  however, a random lottery number selection may also be preprinted on each part, random number selection thereafter by the air carrier still determining winners in either event.

Title: Bound pillared clay for use in the production of alkyl aromatic compounds
Inventor: KOCAL JOSEPH A
IPC: B01J37/00
Filed: 1991-07-18
Granted: 2000-09-26
Abstract: Alkyl aromatic compounds are prepared by reacting at alkylation conditions an aromatic compound such as benzene with an alkylating agent such as an olefin, alkyl halide or alkyl alcohol in the presence of an alkylation catalyst comprising a pillared clay and a binder which has been prepared by dispersing a clay in a metallic pillaring agent sol, separating the resultant pillared clay, washing and drying said pillared clay, forming a dough of said pillared clay and a binder compound, extruding said dough extudate and calcining the resultant extrudate. This catalyst enables improved selectivity for the desired linear alkyl aromatic compound which may then be used in the preparation of biodegradable detergents.

Title: Method and apparatus for finishing a cylinder bore
Inventor: SANTI JOHN
IPC: B24B33/08
Filed: 1993-01-28
Granted: 2001-04-03
Abstract: A method of cutting and finishing a cylinder bore surface yields a highly polished finish having substantially no tool marks. The method includes removing a first thickness of surface material using a diamond-tipped rough cutter disposed on a rotating milling tool head. A second thickness of material is then removed by a diamond-tipped finish cutter also disposed on the same rotating head. The finish cutter removes between 0.0015 to 0.002 inches of material, which corresponds to the majority of the material left in the compressive state after the rough cut step.

Abstract: A dilation balloon (4) for medical use formed of a major amount of a crystallizable polymer such as high molecular weight polyethylene terephthalate with an intrinsic viscosity greater than about 0.7, and a relatively minor amount of an additive polymer that interrupts the crystalline structure of the crystalline polymer in the final product. The final product is a blend that when formed into a balloon (4), exhibits advantageous properties of softness, i.e., compliance and a low folded profile, yet achieves high hoop stress arid consequently high burst pressures. The balloon in the deflated state will thus yield when challenged by the wall of the lumen yet can be inflated to high pressure for performing the dilatation procedure with reduced risk of burst.
