Granted: 2012-07-31
Abstract: Isolated proteins, designated SdrF, SdrG and SdrH, and their corresponding amino acid and nucleic acid sequences are provided which are useful in the prevention and treatment of infection caused by coagulase-negative staphylococcal bacteria such as S. epidermidis. The SdrF, SdrG and SdrH proteins are cell-wall associated proteins that specifically bind host proteins and which each have a highly conserved motif of which the consensus sequence is TYTFTDYVD. The proteins, antigenic portions thereof and anti-SdrF, SdrG and SdrH antibodies are also useful for the identification and diagnosis of coagulase-negative staphylococcal infections. In particular, the proteins are advantageous because they may be used as vaccine components or antibodies thereof, and they may be administered to wounds or used to coat biomaterials to act as blocking agents to prevent or inhibit the binding of coagulase-negative staphylococci to wounds or biomaterials.

Title: Apparatus providing on-line indication of frequency of an ac electric power system
Inventor: YANG LIFENG
IPC: G01R23/02
Filed: 2001-05-09
Granted: 2010-10-05
Abstract: Apparatus for determining the frequency of an ac power signal, includes sensing circuitry to sense the ac signal. In a digital implementation of the invention, a double average of the samples is generated by a processor as the sum of the most recent sample, twice the next most recent sample plus the third most recent sample.  The least mean square of a running window of the most recent double average signals is generated to avoid discontinuities at the zero crossings and to reduce the effects of noise. The frequency is determined from this least mean square value of the window of double average signals. As implemented in a protective relay, a trip signal is generated if the frequency is out of limits.

Granted: 2006-06-20
Abstract: A resistivity tool for use in an LWD system includes an asymmetric transmitt er design with multiple transmitters capable of generating EM signals at multip le frequencies. A pair of receivers (R1, R2) are positioned at one end of the transmitter array to detect the EM signals after they have traversed the region in the vicinity of the borehole. A calibrating transmitter (Tc) is positioned between the receivers (R1, R2), which can be used in two differen t modes of operation. In a first mode, the calibrating transmitter (Tc) is use d to calibrate the receivers (R1, R2) for thermal drift. In this calibration mode, an attenuation correction and phase shift correction can be calculated to correct for thermal drift of the receivers while the resistivity tool is in the borehole. Thus, the thermal drift of the receivers can be re-calibrated as often as desired while the tool is in the well. In a second mode of operatio n, the calibrating receiver may be used to measure the resistivity of the drilling mud in the borehole.

Abstract: L'invention concerne un nouveau type de moteur à combustion interne, le moteur en Z. Dans ce moteur, la partie compression et la partie travail sont dissociées. Un nouveau mélange gazeux est acheminé vers la partie haute du piston, en-dessous duquel une petite chambre se forme, lorsque ledit piston se rapproche de la partie supérieure creuse. Les gaz de combustion s'échappent du cylindre par l'intermédiaire de soupapes d'échappement. Après le renouvellement du mélange gazeux, et avant le remplissage de la chambre supérieure, une seconde compression est effectuée et le mélange explose. L'avance à la compression peut être obtenue autrement que par le volume de travail des pistons conjoints. L'effet latéral du piston est pris en compte au moyen d'un mécanisme à double came.

Granted: 2008-04-01
Abstract: The present invention relates to a bait station comprising a base, a reservoir, a cover, and a latch. The base may be used in two different orientations and includes a first section and a second section. The first section has climbing assisting members and a cavity with a reservoir receiving area, and the second section has side climbing assisting members. The climbing assisting members and side climbing assisting members of the base provide a textured surface that enables insects to crawl into and out of the bait station more easily. The reservoir contains poisonous bait and may be placed in two different positions within the reservoir receiving area to accommodate the two different orientations in which the base may be used. The reservoir includes tapered sides with climbing assisting members. The climbing assisting members provide a textured surface that enables insects to crawl into and out of the reservoir more easily. The reservoir also includes an aperture proximate a corner of the reservoir, which provides an entrance into and out of the reservoir and reduces the rate of evaporation of the poisonous bait. The tapered sides of the reservoir also reduce the rate of evaporation of liquid bait because as the volume of the bait decreases, the surface area of the bait exposed to air flowing in and out of the reservoir is also decreased. Finally, the cover is configured and arranged to fit over the base, and the latch secures the cover to the base.

Abstract: In a method of restoring a tooth, the present invention provides a technique for the removal of cement after bonding a dental construct to a tooth. The effect of 5 cement removal techniques were determined by means of an in vitro study, using extracted human teeth. The best results in terms of leakage scores and interface contour were obtained by the technique disclosed, comprising the following steps: after placement of the construct on the tooth, removing excess cement with a soft, pointed brush, brushing the dental margins with a photocurable dental resin cement which is the same as or different from the dental cement used to bond the construct to the tooth; and, light curing the photocurable dental resin cement. When using resin or resin ionomer dental cements, the technique of cement removal disclosed yields improved marginal adaptation of the cement and a good marginal seal.
