Title: Electronic modules manufacturing
Inventor: OGGIONI STEFANO
IPC: H01L21/68
Filed: 1997-11-27
Abstract: In the manufacturing process of electronic modules a problem could arise when the modules have non-flat top surface. This is due to the fact that most of the automatic picking tools uses a vacuum nozzle to pick and place the module. According to the present invention a flat feature (a cap or a stud) is added to the module. This flat feature can be either fixed on the module or removable after the manufacture in order to reduce the dimensions.

Title: Methods of increasing accumulation of essential amino acids in seeds
Inventor: TARCZYNSKI MITCHELL C
IPC: A23K1/14
Filed: 1996-05-30
Abstract: The present invention provides a method for increasing the levels of essential amino acids in seeds of plants, thereby enhancing the nutritional value of the seeds. The method comprises manipulating the metabolic pathway of the amino acid to provide an increased source of the target free amino acid and, concomitantly, over-expressing a preselected gene coding for the protein containing the target amino acid, such that there is accumulation of protein-bound target amino acid. A complementary protein sink is thus produced. The present invention is particularly useful in increasing levels of methionine, lysine and threonine in seeds.

Title: Positive lock rivet
Inventor: MASSOF EDWARD P
IPC: F16B19/10
Filed: 1998-06-05
Abstract: A positive lock rivet for joining a plurality of panels is composed of resilient plastic material and has a pin and a body having an axial bore. The pin has a head and a shank, the pin shank having a locking means, a break joint adjacent to the locking means and a break portion adjacent to the break joint and opposite the head. The body has a head and a shank. The body shank has a proximal end, a distal end, a collapsible portion and a noncollapsible portion. Integral with the proximal end of the body shank is a retention means and integral with the body shank between the collapsible portion and the body head is a flexible annular skirt positionable between the panels to be joined. The body shank is insertable into aligned holes in the panels. The pin is drawn into the body until the pin head engages the distal end of the body shank, causing collapse of the collapsible portion of the body shank and flexure of the annular skirt until the locking means engages the retention means, thereby tightly locking the rivet assembly. The break portion of the pin shank is then broken off at the break joint flush with the body head.

IPC: B32B27/12
Filed: 1997-02-10
Abstract: A cloth-like microporous laminate of a nonwoven fibrous web and thermoplastic film is made by lamination of a microporous-formable film composition and a nonwoven fibrous web followed by incremental stretching to form the cloth-like microporous laminate. The cloth-like microporous laminate has air and moisture vapor permeabilities, but acts as a barrier to the passage of liquids. The cloth-like laminates are especially useful in fabricating garments in order to provide the breathable qualities of air and moisture vapor transmission with liquid-barrier properties. Such garments include baby diapers, baby training pants, catamenial pads and garments, and the like where moisture vapor and air transmission properties, as well as fluid barrier properties, are needed.

Title: Method of stimulating an immune response by administration of host organisms that express intimin alone or as a fusion protein with one or more other antigens
Inventor: STEWART CHARLES N JR
IPC: A61P37/04
Filed: 1997-04-18
Abstract: This invention satisfies needs in the art by providing intimin, the Enterohemorrhagic Escherichia coli (EHEC) adherence protein, alone or as a fusion protein with one or more other antigens, expressed by transgenic plants and the use of those plants as vehicles for stimulating a protective immune response against EHEC and the one or more other antigens. Various plant species are transformed to protect various animal species and also humans against EHEC, against pathogens expressing intimin-like proteins, and against pathogens expressing any of the one or more other antigens to which intimin may be fused. The eae gene encoding intimin, a functional portion thereof, or a recombination that encodes a fusion protein is put under the control of a constitutive plant promoter in a plasmid and the plasmid is introduced into plants by the type of transformation appropriate for the particular plant species. The engineered plants expressing intimin or the intimin fusion protein are then fed to animals and/or humans to elicit the production of antibodies, which protect the animals/humans against EHEC colonization and infection, and against pathogens expressing the one or more other antigens and any cross-reactive antigens. The invention may also be practiced by expressing the intimin or intimin fusion protein in other host organisms such as bacteria, yeast, and fungi.
