Inventor: KROPF CHRISTIAN
IPC: A61K8/00
Filed: 1999-12-09
Granted: 2010-02-23
Abstract: The invention relates to suspensions of poorly water-soluble calcium salts, selected from the phosphates, fluorides and fluorophosphates, in liquid media, preferably in water, containing suspended primary particles between 5 and 50 nm in diameter and between 10 and 150 nm in length. Said suspensions are stabilized by a contents of at least 0.01 % by weight, in relation to the weight of the suspension, of a water-soluble surface-active agent or water-soluble polymeric protective colloid so as to prevent agglomeration. The suspensions are suitable as remineralizing components in compositions used for the cleaning and care of the teeth.

Title: Mobile rock crusher
Inventor: OLYNYK JERRY
IPC: E01C21/00
Filed: 2001-10-12
Granted: 2006-10-17
Abstract: A mobile rock crusher for crushing raw rock material which has been windrowed on a roadway in the translation path of the crusher includes a rigid supporting structure, which includes a frame, and translation means for allowing translation of the frame over the roadway. A selectively actuable scoop is pivotally mounted to the frame for selectively actuable lowering over the roadway into sliding engagement with, so as to collect, the windrowed raw rock material onto the scoop. A first conveyor is mounted to the frame. An upstream loading end of the first conveyor cooperates with the scoop for conveying the raw rock material from the scoop onto a first screen at a downstream depositing end of the first conveyor. The first screen is for screening larger diameter material from smaller diameter material in the raw rock material so that the smaller diameter material falls through the first screen.  The larger diameter material translates over the first screen so as to fall into a first crusher mounted to the frame beneath the first screen. A second conveyor mounted to the frame beneath the first crusher is for conveying crushed material from the first crusher into a second crusher mounted to the frame for crushing the crushed material for deposition from the second crusher onto the roadway.

Title: Method and device for plugging a gas main
Inventor: MCGIVERY JOHN W
IPC: F16L55/132
Filed: 2002-02-05
Granted: 2010-01-26
Abstract: A method of sealing a pipe and a device for sealing the pipe which prevents gas leakage out of a pipe stub plugged by a stopper disposed in a tee fitting, to allow a permanent cap to be welded onto the pipe. The device comprises an expandable plug comprising a pair of plates with a sealing member disposed between the plates. The plates can be squeezed together, for example by tightening nuts onto bolts extending through the plates to compress the sealing member and cause the periphery of the sealing member to expand against the inner wall of the pipe. Stabilizing means, for example a nut having a reverse thread and a complimentary tool, is provided for stabilizing the expandable plug radially within the pipe as the plates are squeezed together. The expandable plug is inserted into the pipe stub after the bypassed section of pipe has been removed, and lodged in the pipe by squeezing the plates together to expand the sealing member against the inner wall of the pipe stub. The cap is then welded onto the pipe stub.

Title: Digital signal processor with coupled multiply-accumulate units
Inventor: SIH GILBERT C
IPC: G06F7/544
Filed: 2001-02-23
Granted: 2010-06-29
Abstract: Two multiply-accumulate units are coupled together so that the computation (B*C)+(D*E) can be completed in one cycle. An adder (216) adds together the products of the two multipliers (206), (208). The sum is applied to the first accumulator (220). Preferably, the second product is also applied to the second accumulator (222), and a multiplexer (218) applies either a zero or the second product to the adder (216). If two unrelated computations are to be executed simultaneously, then the zero is applied, and the output of the second accumulator is fed back to the register file (PI2). If a single (B*C) + (D*E) computation is to be executed, then the second product is applied to the adder, and the output of the second accumulator is disregarded.

Abstract: Policy-based traffic forwarding in a data network is implemented using policy-based control over propagation of LSA messages through the data network. A route tag is asserted in respect of a link state advertisement (LSA) message advertising a network address. Propagation of the LSA through the data network is controlled using the asserted internal route tag. At each hop, a policy decision affecting the forwarding of the LSA is made. Exemplary policy decisions include, Pass and Discard. In addition, the forwarding table may be updated using the route and address information contained in the LSA. In this case, routes entered in the forwarding table may be tagged as an inclusion route or an exclusion route. This may be based on the value of an exclusion route flag, such as a binary "0" or "1" inserted into an unused portion of the options field of the LSA.

Abstract: A cellular wireless packet data communication system containing transmit-only endpoint devices (HA40, HA50) which transmit to receive-only base stations (B1, B2, BN). The system is configured to allow for large area coverage (e.g., a metropolitan area) with far fewer number base stations than are required with conventional two-way cellular systems. The base station coverage areas are configured to overlap, allowing for reception of packets at multiple base stations. A data concentrator (HA60) resolves redundantly received messages. The network is configurable as a WAN, a LAN, or a combination of the two. Novel modulation techniques (e.g., a 16QAM submodulation together with a 7FSK modulation) are used such that low cost components can be used in the transmitters and receivers while achieving outstanding probability of success performance. The endpoint devices are battery operated and accordingly, are designed for low power consumption and multi-year battery life. The system is used in a variety of applications including remote monitoring and mobile communications.
