  • Hyaluronic acid binding peptides enhance host defense against pathogenic bacteria
    Patent number: 8044022
    Abstract: Several species of bacteria capable of invasive infections, such as S. pyogenes, S. equi and P. multocida, contain hyaluronic acid (HA) in their capsules. Bacterial species such as Staphylococcus aureus and related Staphylococci have capsules that contain acidic polysaccharides. Bacterial capsule or bacterial surface binding peptides were synthesized and tested in a culture model of invasive bacterial infections, specifically translocation through polarized keratinocyte cultures. The peptides reduced the translocation of a variety of bacterial species, with a concomitant increase in bacterial internalization by the keratinocytes. In vivo, subcutaneous inoculation of encapsulated GAS treated with peptides delayed bacterial dissemination. In a mouse surgical wound model infected with S. aureus, treatment with peptides reduced the numbers of bacteria and inflammation at the wound site.

  • Prefabricated building panels and structures, building, methods and systems relating to same
    Patent number: 8033065
    Abstract: Wall and floor structures of a building each comprise a base layer comprising prefabricated panels with grooved inner faces and a covering layer disposed over the panels to cooperate with walls of the grooves to define channels extending along the panels. Selected grooves contain in-floor heating elements and electrical wiring and routing components. A prefabricated corner panel is formed by notching out an oversized channel in the same type of panel, bending the panel along the channel and filling a remaining gap at the so-formed corner bend with a higher r-value insulation than the rest of the panel. Wall and floor panels are joined by a connector having a C-shaped portion that caps exterior floor panel edges and an integral projecting portion inserted into a slot formed in the wall panel's insulating layer at a bottom edge of the floor panel.

  • Device to reduce brain edema by surface dialysis and cooling
    Patent number: 8012116
    Abstract: We have developed a novel method of brain surface dialysis that reduces intracranial pressure and modifies movement of extracellular fluid in a rat model of brain injury. A chamber with a semipermeable membrane at the site of brain contact is perfused with a hyperosmolar solution (e.g. 15% dextran, inulin, hydroxyethyl starch). It is also capable of providing local brain cooling. In principle, osmotic forces draw water and small molecules from the injured brain into the dialysis chamber thereby reducing brain swelling. The dialysate does not move into the brain.

  • Crop harvesting header with rotary disks and impellers for transferring the crop inwardly to a discharge opening
    Patent number: 8006469
    Abstract: A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening and a transfer roller is mounted behind the disks and in front of the nip. At each end, two disks are mounted outwardly of the discharge opening each rotating so that its blade moves inwardly and each carries an impeller to carry the crop inwardly. A third disk is arranged so that a line forward of the end of the discharge opening intersects the third disk inward of the axis of the third disk. The third disk rotates so that its blade moves outwardly so that the crop tends to pass between the second and third disks. A pair of impellers are mounted behind the second disk and move inwardly to carry the cut crop to the discharge opening.

  • Modular street sweeper
    Patent number: 7996955
    Abstract: A modular street sweeper includes a pair of side brooms to sweep debris laterally inwardly from opposing sides of the sweeper and a pickup mechanism to convey the swept debris from the ground to a collection hopper. The pickup mechanism includes a conveyor module in which a main broom at a rear of the sweeper sweeps the debris forwardly onto a rotating conveyor and a vacuum module in which a vacuum head spans laterally across the sweeper in proximity to the ground and communicates with a fan to direct the swept debris into the hopper. The vacuum pick up module is interchangeable with the conveyor pickup module so that a single sweeper investment can perform both a spring function of sand collection with the conveyor and a fall function of leaf collection with the vacuum head.

  • Radial type reciprocating compressor and portable tool powering system with flexing connecting rod arrangement
    Patent number: 7980829
    Abstract: A reciprocating compressor or pump features a manifold arranged not only to define a hollow interior for receiving fluid discharged from a plurality of cylinders but also to define a base or frame on which the cylinders are carried. Unique valves formed in part by flexible material reduces the likelihood of fatigue and increases efficiency by retaining less heat relative to conventional reed valves. A compressor or pump mounted at an end of a handle extending parallel to a motor housing likewise extending from the compressor or pump provides an easy to carry portable assembly. A fan mounted between a motor and a compressor pulls air through the compressor inlet to both cool the motor and feed the compressor. A portable tool system powers both pneumatic and electric tools. Connecting rod structures for radial compressors or pumps provide improved strength and easier assembly.

  • Containment apparatus for containing gestating sows
    Patent number: 7980199
    Abstract: Gestating sows are housed in a series of gestation stalls arranged in a row and backing onto an open alley along a rear of the row of stalls into which the sow can enter by backing out of the stall. A common trough extends along the front of the stalls and is fastened to the floor by fasteners which connect trough sections end to end. The common trough provides a support for the front end of the side walls defining the stalls. A rear gate closes the rear of each stall and connects to a front gate of the stall operable to close the rear gate by the sow as it moves in the stall toward the front. The rear gate latches closed to prevent entry of another sow but is releasable by rear pressure on the rear gate from the sow backing out.

  • Animal feeder with adjustment of a feed discharge opening
    Patent number: 7975648
    Abstract: An animal feeder includes a hopper above a shelf onto which feed can fall to be taken by the animal or dropped into a trough below the shelf. The height of the shelf is adjustable in a course movement to move the shelf from a low height for smaller animals to a raised height for the animal after they have grown. The shelf is also adjustable in fine movement to change the width of the opening through which the feed passes to control feed rate. The shelf is carried on straps which extend along the end walls of the hopper and are movable by an adjustment linkage defined by a plate carried on the end wall and a manually adjustable lever mounted for pivotal movement on the plate. The lever has two pivot positions on the plate providing the two course adjustments and two graduated scales for the fine adjustment each cooperating with a respective pivot position.
