Granted: 1998-05-05
Abstract: An apparatus and method for forming curing envelopes which apparatus and method enable the use of a conventional inner tube mold for making a curing envelope preform in the form of an envelope tube which may have a portion thereof easily removed to provide a curing envelope suitable for use in a tire retreading process. A curing envelope is made by placing an annular tube of uncured envelope material in a curing mold having a center core and a mold insert installed therein. The insert includes a pair of coaxial annular rings projecting radially outwardly from the center core and connecting straps for maintaining the axial spacing between the rings. The mold is closed and heat and internal pressure are applied to the envelope tube for curing the envelope tube and urging the tube against the interior cavity surface with the annular rings penetrating into the inner wall of the tube for forming therein corresponding annular grooves. The mold is then opened and the envelope tube is removed from the mold after which the envelope tube is severed along the annular grooves to remove the portion of the inner wall of the envelope tube between the grooves thereby to form a curing envelope of generally U-shape cross-section.

Granted: 1996-10-29
Abstract: The invention is a tape reel brake which is mounted in a well in the top of a tape reel hub.  The well is inside the tape bearing surface of the hub.  The brake is mounted to be compliantly biased away from the base of the well.  The hub is seated against a first inside surface of a tape cartridge housing.  The hub and brake are seated in the tape cartridge such that teeth on the periphery of the brake are biased against the opposite inside surface of the cartridge housing about the periphery of an opening therein.  The biasing of the brake against the opposite inside surface both prevents the rotation of the reel and shields out dust when the tape cartridge is removed from a tape drive.  To rotate the reel, a tape drive  clutch enters  the  opening  in the  opposite inside surface and depresses the brake into the well to mate with a smaller diameter portion of the hub or a recessed portion of the brake.  The hub is always maintained on the inside surface of the housing,  thereby eliminating lateral motion which could disrupt the tape path.

Abstract: A method and apparatus for eliminating zebra mussel colonizations from fresh water intake pipes for facilities, such as power plants and water treatment plants, are disclosed.  One or more small diameter alternate intake pipes are disposed within a main intake pipe, and the pipes are connected by means of individually controllable valves to a pump for supplying water to the facility.  Zebra mussel build up along the interior walls of any of the pipes is eliminated by shutting off flow in any mussel infested pipes with the valves, which causes starvation of the mussels due to suffocation.  When water flow is resumed, the dead mussels are easily washed out of the pipes.  The alternate intake pipes can be made of inexpensive flexible material, such as rubber, since they are not exposed to the environment external to the main intake pipe.  In addition, a non-stick coating, such as silicone, can be disposed on the interior walls of the alternate pipes to further prevent mussel build up.  A number of techniques for installing the one or more alternate pipes within an existing pipe are also disclosed.

Abstract: An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets. An extractor exhausts the moisture-laden air from an exposure zone while short wave infra-red radiation heats the ink and/or protective coating: The effective exposure to high velocity, hot air is increased by the air jets which produce a balanced pressure air blanket along the sheet travel path. The moist air layer is displaced from the printed and/or coated sheet and is extracted from the press as the sheet moves through the exposure zone.

Title: Altered antibodies, products and processes relating thereto
Inventor: WINTER GREGORY P
IPC: C12P21/08
Filed: 1993-02-19
Granted: 2007-05-15
Abstract: The present invention relates to altered antibodies which are substantially immuno silent by virtue of their containing selected germ-line amino acid residues which replace one or more corresponding somatically mutated residues in a native antibody.  In a process for making a gene for use in preparing such an antibody, one or more somatically mutated amino acid residues in a native antibody are identified as suitable candidate(s) for alteration. A  nucleotide coding sequence is made which codes for selected germ-line amino acid residues to replace the one or more somatically mutated amino acid residues. The altered antibody can have variable (V) regions which comprise complementarity determining regions (CDRs) which provide the antibody with capacity to bind a specific antigen; and a selected and predominantly germ-line framework. In processes for making a gene for use in the preparation of such an antibody, there are the steps of (i) obtaining CDR encoding nucleotide sequences which encode CDRs with specificity for the specific antigen and (ii) combining these CDR  encoding nucleotide sequences with framework encoding nucleotide sequences which encode the selected germ-line framework.
