  • Patent number: 6105357
    Abstract: Method and apparatus for making hollow links or rings and for making chain made from hollow links by receiving seamless wire which has an inner core and an exterior surface, for example, a gold alloy surface, making a perforation in the wire so as to expose the inner core at the perforation, and forming the wire into an open or closed link such that the perforation is located on a hidden portion of the link. The inner core may then be removed from the open or closed link by dissolving it in acid, wherein the acid contacts the inner core at the perforation thus allowing the acid to dissolve the inner core. A chain may be made by coupling each link with at least one preceding link to produce the chain.

  • Patent number: 5911982
    Abstract: Disclosed and claimed is the promoter, full-length or truncated, of the persistence-associated gene 1 (pag1) of Hz-1 virus, vectors containing the promoter, including with exogenous coding DNA, methods employing the vectors, compositions employing the vectors and products therefrom, and probes and primers for the promoter or functional fragment thereof. The promoter of pag1 gene is strong and if not comparable, it is better than the promoter activity demonstrated in the polyhedrin gene in insect cells. In addition, the pag1 promoter can be expressed more prominently as a short promoter. The pag1 promoter can also be expressed in transient transfected and permanently transfected cells. Further, the pag1 promoter can also be expressed when it is inserted into other viruses, such as Autographa californica nuclear polyhedrosis virus. The pag1 promoter has also been shown to express foreign genes strongly, such as in lacZ and luciferase.

  • Patent number: 5819005
    Abstract: A modular digital recording system that records audio on digital audio tapes provides redundancy and the ability to record audio while listening to portions of audio that had been recorded on the DAT. The system uses a hard disc that receives audio for recording simultaneously with the DAT. When one wishes to listen to a voice message, one can activate the hard disc to listen to a particular message while the DAT is still recording. The system is modular so that the capacity can be expanded as required. The system includes a LAN adapter so that the system can provide networking access.

  • Patent number: 5810252
    Abstract: Methods and apparatus particularly useful for atomizing a heavy highly viscous liquid into fine droplets (such as petroleum distillate resid to droplets on the order of 100 thousandths of a millimeter), with the aid of at least one auxiliary gas. This employs in a nozzle head an array of a plurality of primary channels and at least two secondary channels associated with each said primary channel. The primary channels each have an inlet end connected to a high pressure source of liquid, and have an outlet end defining an atomization orifice. The secondary channels each have an inlet end being connected to at least one source of auxiliary gas and an outlet end. The outlets of the secondary channels each intersect with a commonly associated primary channel at the same or different locations upstream of the respective atomization orifice at angles of less than, typically or less. Liquid is passed through a plurality of primary channels thereby forming a liquid core stream.

  • Patent number: 5800706
    Abstract: The general area of this invention relates to porous materials made from nanofiber packed beds. More particularly, the invention relates to altering the porosity or packing structure of a nanofiber packed bed structure by blending nanofibers with scaffold particulates having larger dimensions. For example, adding large diameter fibers to a nanotube packed bed to serve as a scaffolding to hold the smaller nanofibers apart and prevent the nanofiber bed structure from collapsing. This increases the average pore size of the mass by changing the pore size distribution and alters the packing structure of the packed bed. The increase in average pore size is caused by the creation of larger channels which improves the flow of liquids or gasses through these materials.

  • Patent number: 5792268
    Abstract: Apparatus for supporting and holding a circuit board in place in a machine for screen printing a major surface thereof with solder paste. The apparatus includes a member with a surface on which a circuit board rests as the board receives solder paste printing through a screen. The surface has a main groove and distribution grooves that intersect the main groove in communicating relationship therewith at spaced locations along its length. Further, the member has an air removal passageway extending therethrough from one side to the opposite side thereof. The passageway terminates on the one side of the member at an opening located in the main groove. A circuit board resting on the surface over the grooves is held in place during screen printing with solder paste as a result of reduced air pressure established in the grooves when air is withdrawn therefrom through the passageway.

  • Patent number: 5792936
    Abstract: Protoplasts which regenerate reproducibly in a short time to normal, fertile plants can be regenerated from an auxin-autotrophic genotype of Zea mays (L.). Starting from immature embryos on hormone-free media, an auxin-autotrophic, embryogenic callus is formed on the shoot basis of the seedlings, which callus retains its embryogenic potential over a substantial period of time when subcultured on hormone-free medium. In addition to fully-developed embryos, adventitious embryos are also formed under suitable culture conditions (6-9% of sucrose in the medium). When the sucrose content is reduced to 2-3% and 2,4-dichlorophenoxyacetic acid is added, soft, granular calli are formed which consist of embryogenic cell aggregates (type II callus). After subculturing the type II callus in the form of a cell suspension culture, totipotent protoplasts can be isolated. From these protoplasts, the maize plants according to the invention are regenerated.
