Title: Remineralizing products and methods for teeth
Inventor: WINSTON ANTHONY E
IPC: A61K8/00
Filed: 1996-08-02
Granted: 2001-07-31
Abstract: Products and methods are provided for the remineralization of lesions formed in the subsurfaces of teeth and/or mineralization of tubules in exposed dentin of teeth, wherein the products generally contain at least one water-soluble calcium salt, at least one divalent metal salt other than calcium salt, at least one water-soluble phosphate salt, and, optionally, at least one water-soluble fluoride salt. The water-soluble salts are then mixed to form an aqueous mixed solution having a pH of from about 4.5 to about 7Ø Cations released by the divalent metal salt stabilize the aqueous solution such that phosphate and calcium ions released by the salts do not react to any large extent until the product is introduced into the oral cavity and, upon introduction into the oral cavity, the ions do not rapidly precipitate. This gives the cations and anions sufficient time to diffuse through the tooth surface to the lesion(s) and/or tubules where the ions form a precipitate, thereby remineralizing the lesion(s) and/or mineralizing the tubule(s).

Title: Fluid treating apparatus
Inventor: ASHBROOK CLIFFORD L
IPC: B01J19/24
Filed: 1995-07-25
Granted: 2001-10-09
Abstract: An apparatus (10) for treating fluids by increasing the fluid's rate of diffusion, removing minerals in solution, releasing entrained gases, and destroying bacteria includes a pair of cascaded vortex nozzles (26-29) positioned in opposed relation. Each of the vortex nozzles (26-29) communicates with a fluid source (14) to receive a fluid stream which it rotates. The cascaded vortex nozzles (26, 29) feed their rotating fluid stream into the rear of the vortex nozzle (27-28) with which they are cascaded. The rotating fluid streams fed into the vortex nozzles (26-29) combine with the rotating fluid stream within each nozzle. The combined streams then circularly rotate and exit the opposed vortex nozzles (27, 28) to collide in a chamber (30). The collision between the combined rotating streams results in the breaking of the bonds holding the fluid, gases, and minerals in their molecular array.

Granted: 2006-10-17
Abstract: The present invention relates to a safety device (1) for the fuze of a spin-stabilized projectile, said projectile having a detonator carrier (10) that can pivot from a safety position into a firing position.        In order to make it possible to lock the detonator carrier (10) in the firing position in a simple manner, despite the application of only a little force and a high degree of stiffness, the present invention proposes the integration of pivotable locking lever (15) into the safety device (1), this locking lever being actuated and pivoted by the detonator carrier (10) when the detonator carrier is pivoted. As soon as the detonator carrier (10) has reached the firing position, a detent catch (16) that is formed on the locking lever and appropriately shaped engages in a cutout (21) in the detonator carrier in such a way that the detonator carrier (10) cannot pivot back.
Patent CA-2245072-C (CA)

IPC: H04L27/36
Filed: 1998-08-17
Granted: 2003-10-21
Abstract: A One Bit Digital Quadrature Vector Modulator (DQVM) and a method of generating single sideband output signals are useful for a wide range of radio frequency, signal processing and wireless applications. The DQVM simplifies the necessary digital multiplication by using noise shaped one bit versions of both the baseband I B and Q B signals to be modulated and the I LO and Q LO modulating signals. The one bit DQVM enables a much faster digital implementation of the digital quadrature vector modulation function than can be achieved with conventional multi-bit digital techniques. In addition the single sideband upconversion of the DQVM achieves high suppression of the unwanted sideband by applying an offset to one of the low speed input samples. Digital vector modulators are an improvement over conventional analog vector modulators as they are not subject to the amplitude and phase matching problems inherent in analog vector modulators.

Title: Method and apparatus for measuring nuclear magnetic resonance
Inventor: TAHERIAN REZA
IPC: G01V3/32
Filed: 1998-08-28
Granted: 2001-07-24
Abstract: The present invention relates generally to an apparatus and method for measuringnuclear magnetic resonance properties of an earth formation traversed by a borehole by generating gradient-echoes. The measurement can be made while drilling or using a wireline tool. The apparatus applies a static magnetic field, B a, in a volume of the formation which polarizes the nuclei of hydrogenous connate fluids within the formation. The apparatus applies a second magnetic field, B b, in a volume of the formation. The magnetic fields B a and B b are substantially orthogonal in the volume of the formation. A change in the polarity of the magnetic field, B b, reverses the direction of precession of the nuclei thereby generating a train of gradient-echoes. Each gradient-echo signal is transformed into the frequency domain and the signal frequency is mapped to a radial position in the volume of the formation in order to generate an image of the formation. Various properties of the formation, such as the effective diffusion coefficient of the formation fluid, longitudinal relaxation time, spin-spin relaxation time, and porosity can be estimated from the train of gradient-echoes.

Title: Conveyor system with driven roller transfer assembly
Inventor: LAYNE JAMES L
IPC: B65G47/26
Filed: 1997-04-14
Granted: 2005-06-28
Abstract: A conveyor system having an improved conveyor transfer assembly (10) is provided for transferring articles from the end of a first conveyor to the start of a second, in-line conveyor. The conveying surface o f the transfer assembly is formed by rollers (26) driven by a magnetic coupling system (40) which delivers power from an independent power source (44, 46). In addition, magnets (60, 62) are used for providing a positive attachment between the conveyor transfer assembly (10) and the conveyor supports (20) which span between the first and second conveyors. Thus, when an article jam occurs adjacent to the transfer assembly, the positive magnet attachment is overcome and, likewise, the magnetic coupling between the power source (44, 46) and t he rollers (26) is also overcome thereby releasing the power connection. This allows the transfer assembly (10) to be bodily lifted and released to prevent damage to the articles. The transfer assembly (10) may also contain a tether (98) connected to the frame to restrain and suspend the transfer assembly following its release.
