  • Publication number: 20040033585
    Abstract: Herein described are various methods for making a vaccine that are made of re-assembled virus like particles (VLP). First, the VLPs are disassembled into encapsidation intermediate populations. Each encapsidation intermediate population undergoes, for instance, chemical conjugation of unique peptide or nucleic moieties to form separate populations. Thereafter, a predetermined amount of each of the several (one or more) different encapsidation intermediates from the different populations is mixed and joined, forming intact VLPs, surrounding a nucleic acid core, that are composed of different encapsidation intermediate such that the reassembled VLP displays more than one peptide or nucleic acid. The nucleic acid can function either as a scaffold alone or can be engineered for the expression of an immunomodulatory protein in a eukaryotic cell.

  • Publication number: 20030157495
    Abstract: We describe here an in vitro method of increasing complementarity in a heteroduplex polynucleotide sequence. The method uses annealing of opposite strands to form a polynucleotide duplex with mismatches. The heteroduplex polynucleotide is combined with an effective amount of enzymes having strand cleavage activity, 3′ to 5′ exonuclease activity, and polymerase activity, and allowing sufficient time for the percentage of complementarity to be increased within the heteroduplex. Not all heteroduplex polynucleotides will necessarily have all mismatches resolved to complementarity. The resulting polynucleotide is optionally ligated. Several variant polynucleotides result. At sites where either of the opposite strands has templated recoding in the other strand, the resulting percent complementarity of the heteroduplex polynucleotide sequence is increased. The parent polynucleotides need not be cleaved into fragments prior to annealing heterologous strands. Therefore, no reassembly is required.

  • Publication number: 20030104571
    Abstract: A plurality of proteins of interest, or peptides of interest, or other genetically expressed materials, are screened and subsequently produced using any of a variety of expression systems. The plurality of proteins are extracted from a plurality of separate, processed green juices, each green juice containing one of the proteins of interest. A multi-channel apparatus processes the various green juices, one green juice per channel. The apparatus is computer controlled such that the various valves in each channel and pump are controlled in an automated manner to extract each protein of interest and deliver each protein of interest into its own storage vessel.

  • Patent number: 6237190
    Abstract: A door check for holding a door in an open position is disclosed, which is particularly useful for thin doors. The door check comprises a check body attached to the door and having an opening. The door check pivots with the door about a first axis. A main link is slidable through the door check opening as the door pivots. A second link is pivotably attached to the main link, and pivotably about a second axis with respect to a rigid member. As the check body pivots about the first axis, the second link pivots about the second axis and the main link translates through the opening in the check body. The main link may have an irregular surface so that a large force may be required to move the door back from the open position to a closed position.

  • Patent number: 6009932
    Abstract: A push to exit, pull to enter latch assembly is disclosed, particularly suitable as a screen door latch for a recreational vehicle door assembly having a main closure door and a screen door. The latch assembly comprises a latch housing, a latch bolt linearly slidable from a latching position to an unlatching position, a push-to-release lever mounted on one side of the latch housing and a pull-to-release lever mounted on an opposite side of the latch housing. In certain preferred embodiments each release lever has a handle and a latch bolt engagement flange. Rotation of either release lever from its normal position to its releasing position forces the corresponding latch bolt engagement flange against the latch bolt, urging the latch bolt from the latching position to the unlatching position. The latch assembly may cooperate with a screen to close an opening in a pivotable screen door.

  • Patent number: 5596757
    Abstract: A system which determines whether one of a plurality of peripheral devices on a SCSI bus is providing termination power to a bus terminator and provides termination power from a power supply associated with a host device only when none of the peripheral devices are providing termination power. The system is further configured to only provide termination power from the host device when information signals are likely to be present on the information bus. Specifically, the system only provides termination power when the host device seeks access to the information bus to thereby limit consumption of the host device's power supply.

  • Patent number: 5555209
    Abstract: A circuit for latching data signals emanating from a DRAM memory for an extended period of time. The circuit is implemented on an ASIC chip which is positioned external to an FPM DRAM-type memory device. The circuit is organized to have a system transceiver, a memory transceiver, a data-in bus, a data-out bus, and control logic. The data-in bus is directly connected to a memory processor or controller through the system transceiver and the data-out bus is directly connected to the memory through the memory transceiver. The data-in bus is connected to the memory through a tri-state buffer positioned in the memory transceiver and the tri-state buffer is normally in an on position thereby normally connecting the data-in bus to the memory. The data-out bus is connected to the memory processor through a tri-state buffer which is normally in an off position. Hence, the circuit is normally configured to write data.

  • Patent number: 4949340
    Abstract: A redundant repeater connected between two transmission mediums that can operate in a repeat state where packets are repeated between the mediums, and a standby state where no packets are repeated and where the repeater determines whether packets are being properly repeated between the transmission mediums by another device. If the repeater determines that packets are being independently repeated it remains in the standby state, and will attempt to leave the standby state and return to the repeat state only if it determines that packets on one medium are not being repeated to the second medium. Two repeaters can be redundantly connected across the same transmission mediums with one operating in repeat state and the other in standby. If one repeater fails, the other will begin repeating all received packets. The repeater determines whether packets are being properly repeated by detecting overlapping or non-overlapping packets between its two transmission mediums.

  • Patent number: 4273017
    Abstract: A piano action keyboard for an electronic musical instrument or the like wipes a switch actuator (or other mechanical component of electric signal translation means) across switch contacts on a printed circuit board to generate signals indicative of the position and motionof a key when played. The keyboard provides a highly realistic piano "feel" through an array of paired depressable playing keys and arms. Each such arm supports a switch actuator or the like, with varying force transmission at different stages of depression of its corresponding key, the overall electrical-mechanical combination affording a response in terms of both actual results and kinesthetic feedback simulating a manual piano action.
