Title: Air admittance valve for sanitary waste pipe system
Inventor: ERICSON KURT STURE BIRGER
IPC: F16K24/00
Filed: 2000-02-02
Granted: 2006-09-19
Abstract: The invention relates to a valve for admitting atmospheric air into the waste pipe system in response to a pressure reduction in the system in order to protect the water traps in the system and to prevent discharge of contaminated air from the waste pipe system to the atmosphere. The valve consists of a valve body (10) having at least two air inlet openings (30) in communication with the atmospheric air, each of the openings (30) alternating with a passage (14) towards the waste pipe system, said openings and passages (14) being equally distributed within the valve housing (20) when considering a cross-sectional view in a horizontal plane about the valve seat level (H). The valve member (34) resting, in normal closed position, on the valve seat (24) separating said openings (30) from said passages (14) and having a substantially butterfly shaped sealing surface in case of a valve embodiment having two diametrically opposed openings (30) situated perpendicular to respectively two diametrically opposed passages (14). In order to obtain a balanced air distribution within the valve body, the total surface of the air flow passage through the open valve function elements (24, 34, 64) should be substantially equal to the total surface of the air inlet openings (30).< /SDOAB>

Title: High dispersion fibers for high-speed transmission
Inventor: ESSIAMBRE RENE-JEAN
IPC: H04B10/02
Filed: 2002-02-08
Granted: 2005-12-06
Abstract: The specification describes an optical transmission system for high speed, high capacity digital pulse transmission, i.e. at least 10 Gb/s at a duty cycle of at least 10%, which uses transmission fiber with a dispersion value greater than 20 ps/(nm-km) or more negative than -5 ps/(nm-km). The system operates in the pseudo-linear transmission mode (PLTM). In the PLTM it was discovered that pulse distortion decreases, i.e. eye closure penalty actually decreases, as the dispersion value increases. System performance actually improves by increasing the value of absolute dispersion of the transmission fiber.

Title: Noise attenuating insulated heat shield
Inventor: CHEN COLIN CHING-HO
IPC: F16L59/08
Filed: 2002-12-02
Granted: 2010-03-30
Abstract: An improved heat shield offers both a thermal insulation and reduced noise transmission for vehicular engine components, including exhaust manifolds, for example. The structure has three layers: an outer structural metal layer, a center insulation layer to isolate heat and dampen noise, and an inner metal layer directly adjacent the shielded component for reflecting heat back to the shielded component. As disclosed, the heat shield includes at least one bolt aperture for attachment of the shield to a shielded component, such as an exhaust manifold in the described embodiment. The aperture is circumferentially bordered by at least one non- planar undulation defining a protuberance. The protuberance is spaced circumferentially about the aperture. As the bolted connection of the heat shield to the manifold is a major source of vibration transmittal from the manifold into the shield, the protuberance is effective to dampen the vibration, and hence noise associated with the vibration.

Abstract: The present invention relates to a method and a device for measuring the pressure p in an eye, the so-called intraocular pressure. The method include s a contact body with a known geometry being pressed against the eye with a gradually increasing contact force F and that when the area of deformation o f the eye A can be determined, the pressure can be obtained from the relation P=F/A, whereby the frequency characteristic of a contact body associated wit h a sensor system oscillating in resonance is read, the contact body is presse d against the eye to form a new system oscillating in resonance, the contact force and frequency characteristic for the new system is read, and the chang e in frequency characteristic is calculated. In this way, the pressure of the eye can be determined since the sought deformation area A is a function of t he change A(fch ar). The device has a contact body (4) for pressing against the eye (1) and a means (3) of determining the force with which the contact body is pressed against the eye, whereby the contact body (4) is part of a system oscillating in resonance, and the resonance system is connected to a means ( 9) for reading the frequency characteristic of the system.

Abstract: In the present invention a tubular blank and an article such as a bushing (50) to be assembled are loaded into a die. The tube (40) is hydroformed using typical methods and, while the blank is still pressurized, a punch pierces a hole in the tube. The punch also has an article loaded onto it and, as the punch advances, the article is pushed into the tube through the pierced hole.

Granted: 2007-12-04
Abstract: To prevent an ignition plug from becoming wet with unburned fuel due to a lack of enough rotating power when the engine is started by a kick. A crankshaft reference position detector 25 determines whether a crankshaft pulser signal corresponds to the top dead center of an intake stroke. If the crankshaft pulser signal is from an intake stroke, then a crankshaft angular velocity detector 26 detects a crankshaft angular velocity. The crankshaft angular velocity is represented by the time of a stage. The time of the stage is input to a comparator 27, which compares it with a reference time Tref. If the crankshaft angular velocity is larger them a predetermined value, then a duty cycle for a fuel injector is calculated. If the crankshaft angular velocity is smaller than the predetermined value, then a duty cycle indicative of a fuel injection quantity is set to zero.

Abstract: A member of a new class of bacterial toxin has been isolated and characterised. The bacterial toxin is of the AB5 type and is characterised in that it has a subtilase domain. It is cytotoxic to Vero cells, and toxicity in vivo in mice occurs in a number of different sites. Mutation of the serine active residue results in greater than 99% reduction in activity. The protein has been purified and antibodies have been prepared for both the A subunit and B subunits, and ELISA detection methods have been developed. The nucleic acid sequence has been determined and primers specific for the toxin have been used for a preliminary screen of a range of patient samples to ascertain the extent to which the toxin is present.
