Title: Methods for converting lower alkanes and alkenes to alcohols and diols
Inventor: MILLER JORGE
IPC: C07C31/02
Filed: 1999-05-17
Abstract: The present invention is directed to methods for converting lower alkanes and alkenes to the corresponding lower alkanols and diols. In the methods of the present invention, a gaseous halogen, preferably bromine, is produced by decomposing a metal halide in a liquid having a melting point below and a boiling point above the decomposition temperature of the metal halide. The preferred liquid is molten, hydrated ferric chloride maintained at a temperature between about 37-280 °C. The lower alkane or alkene is halogenated in a gas phase reaction with the produced halogen. The alkyl halide or alkyl dihalide is contacted with a metal hydroxide, preferably an aqueous solution of ferric hydroxide, to regenerate the metal halide and produce the corresponding lower alkanol or diol. The present invention is particularly efficient for converting methane to methanol using ferric bromide to provide the halogen.

Patent CA-2337648-A1 (CA)
Inventor: KRAUS RICHARD B
IPC: B22D17/28
Filed: 2001-02-20
Abstract: A nosepiece for directing a charge into a crucible of a furnace. The nosepiece comprises a completely enclosed sleeve which more accurately directs the charge into the crucible. The sleeve has a distal portion that deflects the charge toward a center area of the crucible, thereby minimizing impact of the charge on the top edge of the crucible and its refractory finer. In addition, the nosepiece is split so that the distal portion is movable, thereby to provide access to an interior of the nosepiece.  As a result, any bridging in the charge may be addressed by moving the distal portion to an open position.

Title: Methods to reduce variance in treatment studies using genotyping
Inventor: JONES HYWEL B
IPC: G01N33/557
Filed: 1999-12-01
Abstract: The present invention provides methods, computer programs and computerized systems useful for evaluating the efficacy of various types of treatment procedures (e.g., clinical trials) as a function of the genotype of a subject.  By matching treatment and control groups genetically (100) the methods and systems of the invention reduce the total variance of the study, thereby allowing trials examining the efficacy or effect of treatment procedures to be conducted with fewer subjects, with increased confidence values, and/or with increased precision or discriminatory power. Certain methods of the invention involve selecting treated and control subpopulations of subjects from treated and control populations for similarity in polymorphic profile (102), wherein the treated and control populations have been treated with a treatment and control procedure, respectively. A determination is then made whether there is a statistically significant difference (104) in a test parameter between the treated and control subpopulations as an assessment of the test procedure (108).

Title: Methods for reducing the flammability of cellulosic substrates
Inventor: REARICK WILLIAM A
IPC: D06M13/00
Filed: 1999-11-12
Abstract: Methods of rendering cellulosic materials fire retardant, and articles of manufacture including the materials, are disclosed. The methods involve applying a flame retardant composition to the material. In one embodiment, t he composition includes a carboxylic acid-containing compound in the substantia l absence of a phosphorous-based esterification catalyst or a basic, (i.e., metal alkoxide) catalyst. The material is heated to esterify at least a portion of the hydroxy groups. In another embodiment, the compositions inclu de an amino acid, protein and/or peptide and optionally include one or more crosslinking and/or coupling agents. Enzymes are a preferred protein. The methods involve applying the composition to the material, and optionally involve covalently linking the amino acid, protein and/or peptide to the material, either directly or via a crosslinking agent. In a third embodiment , the compositions include one or more crosslinking agents, and, optionally, o ne or more phosphorus-based compounds. Dimethyloldihydroxyethylene urea, imidazole, imidazolidinones, dialdehydes, and dichlorotriazines are preferre d crosslinking agents. The methods involve applying the composition to the material, and covalently linking the crosslinking agent to the material. An advantage of covalently linking thecrosslinking agent to the cellulosic material is the lack of any potential toxicity associated with uncrosslinked  fire retardants on the cellulosic material and the stability of the bonds between the material and the crosslinking agent to conventional steam cleani ng and other carpet cleaning methods. In a preferred embodiment, the fire- retardant cotton-fiber composition is used to prepare cotton carpets or rais ed surface and lightweight apparel.

Title: Rotary shaft axial elongation measuring method and device
Inventor: KONDO MITSURU
IPC: G01B7/24
Filed: 2001-08-17
Abstract: Rotary shaft axial elongation measuring method and device enable an accurate measuring of a rotary shaft axial elongation regardless of sizes of the elongation. Grooves (10, 12), arranged mutually opposing in a turned V shape along axial direction, are provided in a rotational surface of a rotary shaft (1), axial elongation of which is to be measured.      A sensor (14) is arranged opposing the rotational surface of the rotary shaft (1). The sensor (14) generates pulses upon passing of the grooves (10, 12) following rotation of the rotary shaft (1). As a circumferential interval between the grooves (10, 12) differs according to the axial directional position of the rotary shaft (1), if the positions of the grooves (10, 12) at the position of the sensor (14) change due to the axial elongation, interval of the pulses generated by the sensor (14) changes. Thus, by the change in the pulse generation interval, the axial elongation is measured.

Abstract: Persons such as travellers in an airport are given an opportunity to remove them-selves from being under suspicion of terrorism or the like. Persons are provided with one or more opportunities to reveal information about themselves by way of a per-sonal disclosure that would normally be unacceptably invasive if such disclosure were mandatory. The nature of the personal disclosure is such that almost all persons frequently choose to make such a disclosure in their ordinary day-to-day lives, but would be offended if required to make the same disclosure. In one embodiment, per-sons are given an opportunity to use an airport lounge spa facility with separate showers, saunas, steam rooms, and whirlpool baths, for men and women. Clothing is safely held (and possibly inspected) by locker room attendants while patrons are using the spa. A method of cost management is provided, whereby the reduction in suspicion (by way of the personal disclosure) of the large numbers of people using the spa is translated into a cost savings in terms of underwriting insurance, or the like, whereby this cost savings funds the construction of the voluntary personal disclosure facility. In another embodiment patrons are offered a free medical exam or health diagnostic that includes a personal disclosure, such as undressing, being scanned, or the like. Other embodiments include an opportunity to play a free Virtual Reality (VR) game using VR goggles having a retinal scanner, or an opportunity to play a free video game by pressing a fingerprint scanner to generate a virtual world from a magnified video image of the participant's thumb.

Abstract: The present invention relates to a tooth whitening strip of material having a shape adapted to fit a user's teeth. Each user has four front teeth, two canine teeth and additional back teeth, such as molars. Each tooth has a front side, a tip, and a back side. The strip of material is of a shape so that the strip will substantially cover the front side of at least the user's front four teeth and two canine teeth. The front sides of additional teeth may be covered. The tooth whitening strip will then fold over the tips and onto the back side of one or more of the front four teeth. However, the strip of material will not cover the tips of the two canine teeth.      The strip of material may be of any shape that allows for the canines to protrude. Possible shapes include substantially trapezoidal with or without stair stepped sides or notches, and rectangular with notches, stair stepped sides, or recesses.
