  • Patent number: 7615187
    Abstract: This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.

  • Patent number: 7371030
    Abstract: A construct from which a flexing road surface may be produced. A flexing road surface provided in accordance with the invention enables a vehicle to pass over the road surface relatively smoothly, while simultaneously imparting a reciprocating motion to the road surface. This reciprocating motion may be extracted at a takeoff point on the construct, and used as motive means for operating an electrical generator, air compressor, pump, or other useful mechanical device.

  • Patent number: 6987353
    Abstract: Provided herein are novel phosphors useful in the manufacture of white light emitting diodes. The phosphors provided by the invention are described by the formula: described by the formula: ZnSxSey:Cu,A in which x and y are each independently any value between 0 and about 1, subject to the proviso that the sum of x and y is equal to any number in the range of between about 0.75 and about 1.25; wherein A is optional and comprises at least one additional element selected from the group consisting of: Ag, Al, Ce, Tb, Cl, I, Mg, and Mn, including mixtures thereof, and wherein Cu is present in any amount between about 0.0001% and about 5% in mole percent based on the total molar weight of said composition. Standard techniques used in phosphor deposition for the manufacture of light emitting diodes which comprise phosphors may be employed to produce LED's having a white light output when the phosphors of the invention are utilized.

  • Patent number: 6588168
    Abstract: Provided herein are blocks useful in the construction of walls and other structures. The blocks include in their design features which render them to be interlocking, and which provide for a wall constructed from the blocks to include a plurality of horizontal and vertical channels that are adapted to receive reinforcing rods (“rebar”). Once a two-dimensional network of rebar is disposed in the interior of such a wall constructed from blocks according to a preferred form of the invention, a castable concrete may be poured into the wall and caused to exist in the spaces between the rebar and the blocks of the invention. By such construction, a wall comprising concrete in its interior that is reinforced in two dimensions is provided, wherein reinforcement in the third dimension is provided by the interlocking feature of the tops and bottom portions of blocks in adjacent rows with one another.

  • Patent number: 6564394
    Abstract: Provided herein are articles of headwear which comprise a top portion, a bottom portion, a right side portion, a left side portion, a front portion, and a rear portion, which collectively define a casing having an inner volume. The bottom portion is equipped. with a removable closure means which has a flat surface to enable the headwear articles of the invention to rest in an upright position when placed on a flat surface. The headwear articles according to the invention have the dual function in that they are useful as feeders or shelters for small birds and other animals, and thus include at least one hole in either of the top portion, a right side portion, a left side portion, a front portion, and a rear portion to enable birds and/or small animals to enter the article when it is placed in a location where such small animals inhabit.

  • Patent number: 6560642
    Abstract: This invention relates to a method of establishing an Internet Protocol network with several IP hosts and with an IP gateway for connecting the IP network to the Internet. The invention provides a method which no longer requires the knowledge of address mechanisms of the Internet protocol previously necessary for a successful establishment and thus protects disturbances of errors during the establishment of an Internet Protocol network.

  • Patent number: 6398720
    Abstract: Provided herein is a device useful in causing enlargement of a flaccid penis. The device includes a first and a second semi-bulbular shaped member portions which are hingably connected to one another and closable to form a bulb shaped device having a hollow interior volume. A flaccid penis may be inserted into a device according to the invention and a vacuum is applied to force blood from the subject into the penis, thus causing enlargement of the penis. Methods for use of the device are provide.

  • Patent number: 6383143
    Abstract: This invention relates to respiratory sensors having a more favorable construction and method of attachment to the human body than analogous devices found in the prior art. Through use of the present invention, the gathering of accurate data over the passage of a greater time span than was previously possible may be readily achieved. Such higher quality data may be used by medical and other professionals to more accurately assess, study, and diagnose particular medical conditions, as well as body function and response to applied stress.

  • Patent number: 6360619
    Abstract: The present invention provides a valve device by which samples of fluid materials may be removed from tanks, conduits, pipes, or sealed streams in which or through which they are caused to reside or travel. The device of this invention contains a reduced number of connections than devices of similar import in the prior art and further include an enhanced safety provision which prevents fluid leakage and inadvertent disconnection between the valve of this invention and a receptacle that is intended to receive the sample. The device of this invention is especially well-suited for use in routine sampling of the quality of aviation gasolines, turbine fuels, or the like at their point of use for contaminants detectable by a filtration method. However, a valve assembly according to this invention may be used in other applications requiring an accurate sample of material to be safely taken from containments which include inter alia, the aforementioned vessels.

  • Patent number: 6194007
    Abstract: Disclosed herein are compositions which are highly effective rodenticides. The compositions include a plurality of glass whiskers which rodents are naturally attracted to for purposes of nest building, or are otherwise induced to pick up in their mouths. Upon biting the whiskers for either transport or eating, the rodents oral mucosa becomes irritated, often to the extent that the rodents are unable to subsequently eat without excruciating pain. Hence, the rodents death by starvation is inevitable.
