Title: Slurry compositions for diffusion coatings
Inventor: SHANKAR SRINIVASAN
IPC: C23C10/30
Filed: 1999-07-15
Abstract: Slurry coating compositions are provided for metal substrates, particularly nickel or cobalt-containing alloys, that enable inward-type diffusion aluminide coatings having a substantially uniform coating thickness to be formed thereon. Substantially uniform coating thicknesses are achieved independent of applied slurry composition thickness or application method. The slurry coating composition of the invention comprises a Cr-Al alloy containing about 50 wt% to about 80 wt% Cr in the alloy, LiF in an amount greater than or equal to 0.3 wt% of the Cr-Al alloy, an organic binder, and a solvent.
Patent CA-2278441-A1 (CA)
Inventor: DEVAULT BRYAN C
IPC: G01V1/28
Filed: 1999-07-23
Abstract: The present invention provides a method for interpreting shear-wave seismic data to detect fractures in the subsurface of the earths crust. Seismic shear waves are acquired along medium symmetry planes and their corresponding AVO intercepts and gradients are estimated. The resulting AVO attributes are combined using a weighted least squares solution to estimate the change in splitting parameter and fast shear velocity, which are diagnostic of the presence of fractures. The method is also useful in assessing the porosity of the subsurface. Knowledge o.f subsurface fracturing and porosity is useful in locating, for example, oil and gas wells.

Patent CA-2290624-A1 (CA)
Inventor: LOUIE-HELM JENNY
IPC: A61K9/22
Filed: 1998-06-05
Abstract: Drugs that are freely or highly soluble in water are formulated as unit dosage forms by incorporating them into polymeric matrices comprised of high molecular weight hydrophilic polymers that swell upon imbibition of water. The dosage form can be a single compressed tablets, or two or three compressed tablets retained in a single gelatin capsule. The oral formulation is designed for gastric retention and controlled delivery of an incorporated drug into the gastric cavity, and thus administered, the drug is released from the matrix into the gastric fluid by solution diffusion. The swollen polymeric matrix, having achieved sufficient size, remains in the gastric cavity for several hours if administered while the patient is in the fed mode, and remains intact long enough for substantially all of the drug to be released before substantial erosion of the matrix occurs. The swelling matrix lowers the accessibility of the gastric fluid to the drug and thereby limits the drug release rate. This process, together with diffusion retardation by selection of specific polymers, polymer molecular weights, and other variables, results in a sustained and controlled delivery rate of the drug to the gastric environment.

Title: Card insertion system with multireadly
Inventor: HILL JEFFREY L
IPC: G06K5/00
Filed: 1998-05-19
Abstract: A smart card verification insertion system (10) for inserting smart cards (30) into corresponding carriers (50) only after verifying the card data read with a mag stripe reader (72), an embossed character reader (74), an IC chip reader (64), and a first bar code reader (68) and a back bar code reader (70) and data encoded on the printed carrier read with a carrier reader (106) correspond to one another and also correspond to account data stored in a smart card account data memory (67). If it is determined that the card has been incorrectly prepared, an incorrect card reject mechanism (96) is actuated by a verification controller (66) in response to the mismatch. Similarly, if the data read by the carrier reader (106) does not match the data read from the card or retrieved from the smart card account data memory (67), a mismatch card reject mechanism (110) is actuated.

Title: Orthogonal frequency division multiplexing based spread spectrum multiple access
Inventor: LAROIA RAJIV
IPC: H04W72/04
Filed: 2000-02-11
Abstract: An orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access system using offsetting between cells, and in particular, the use of tone offsetting and time offsetting, is disclosed. More specifically, frequencies that define the tone set of one cell is offset from the frequencies that define the tone set of at least one adjacent cell. In other words, if a first base station is using tones F1, F2, ..., F N within a frequency band, then a second base station adjacent to the first base station uses tones F1+.DELTA.f, F2+.DELTA.f ..., F N+.DELTA.f within the same frequency band.  Furthermore, the symbol timing of the base-station of one cell may be offset from the symbol timing of the base-station of an adjacent cell. Thus, if a first base station starts successive symbols at times T1, T2, and T3, then a second base station adjacent to the first base station starts its respective corresponding successive symbols at times T1+.DELTA.t, T2+.DELTA.t, and T3+.DELTA.t. For example, in a cellular system with hexagonally shaped cells, the tone sets of two adjacent cells are offset by 1/3 of the spacing between adjacent tones, and the symbol timings of two adjacent cells are offset by 1/3 of a symbol period. Advantageously, the intercell interference is more uniformly distributed among users in a cell.

Title: Device for securing the stationary jaw of a jaw crusher
Inventor: OSTERGAARD DAVID A
IPC: B02C1/04
Filed: 2000-02-14
Abstract: A device for securing the stationary jaw to the frame of a jaw crusher is disclosed. The device includes a crusher frame having top and bottom spaced apart cross members, a stationary jaw, and a threaded draw rod having a pair of inwardly moveable wedge members. The stationary jaw includes a top edge, a bottom edge, and a pair of interconnecting sides, and further includes a top lug adjacent the top edge and a bottom lug adjacent the bottom edge. The top lug is adapted for placement adjacent the frame top cross member, and the bottom lug is adapted for placement adjacent the frame bottom cross member. The draw rod is disposed such that the wedge members are positioned to engage the jaw top lug and the frame top cross member. Accordingly, in response to inward movement of the wedge members, the stationary jaw is progressively more firmly secured to the frame, thereby preventing undesired movement of the stationary jaw during operation of the crusher.

Abstract: A sheet handling system for a sheet transport path of a reproduction apparatus having a sheet skew correction system being fed image substrate sheets in the process direction by a sheet transport system, wherein it is desired to positively feed and yet effectively deskew a wide range of different lengths of sheets in the process direction. A plurality of identical but independent sheet transport units may be provided spaced along the sheet transport path in the process direction engageable with a sheet being fed through sheet transport path for positively feeding even very short sheets from one sheet transport unit to another and to the skew correction system.

A  different selected number of the sheet transport units are disengaged in response to a different sheet length control signal. A single stepper motor rotating a common camshaft in each unit may be used to reliably lift all the idlers of all the nips to be disengaged.

Patent CA-2302380-A1 (CA)
Inventor: LITWIN MICHAEL MARK
IPC: B01J20/22
Filed: 2000-03-22
Abstract: The method measures hydrogen sulfide concentrations in hydride gases in a sealed vessel.      The sealed vessel has a gas inlet to receive a stream of hydride gas, a gas outlet to remove the stream of hydride gas and a metal acetate substrate. The stream of hydride gas contains a concentration of hydrogen sulfide gas. Introducing the stream of hydride gas through the gas inlet contacts the acetate substrate with the stream of hydride gas. Reacting the hydrogen sulfide gas contained in the stream of hydride gas with the acetate substrate modifies optical properties of the acetate substrate. Then measuring the optical properties of the acetate substrate determines the concentration of the hydrogen sulfide gas contained in the stream of hydride gas.
