Abstract: A process utilizing a particulate catalyst, or particulate catalyst admixed with particulate heat transfer solids for conducting high temperature fluidized bed syn gas operations. Hydrogen and carbon monoxide are produced from a low molecular weight hydrocarbon by contact thereof, at high temperature in the presence of oxygen, or steam and oxygen, with a fluidized bed comprising said particulate solids. In one of its forms, barium hexaluminate is employed as a heat transfer solid, in concentrations ranging generally from about 10 wt% to about 99.9 wt%, in admixture with a particulate catalyst containing a metal, or metals, component catalytic for the production of hydrogen and carbon monoxide from low molecular weight hydrocarbons contacted with a fluidized bed of the catalyst at high temperature hydrothermal conditions. The catalyst, suitably one having a barium hexaluminate carrier component, is employed in concentration ranging generally from about 0.1 wt% to about 90 wt%. Such an admixture provides a particularly useful catalytic contact mass for conducting fluidized bed synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the catalyst having a barium hexaluminate carrier component, or barium hexaluminate heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed.      Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.

Abstract: The determination and/or monitoring of a predetermined material level in a container is effected with the help of a material level sensor which contains a mechanical oscillatory structure, an electromechanical excitation transducer and two electro-mechanical reception transducers. The mechanical oscillatory structure is secured at the height of the predetermined mate-rial level in such a way that it comes into contact with the material when said material reaches the predetermined material level. Each reception transducer is connected to the input of an assigned circuit channel, which contains an amplifier cir-cuit, the output of which is connected to the excitation trans-ducer and which is so constructed that the mechanical oscilla-tory structure is excited to produce oscillations with its natural resonance frequency. The two circuit channels are acti-vated alternately by means of a control circuit. Furthermore, each circuit channel contains a measuring signal transducer which produces a measuring signal which on the one hand con-tains the information about the frequency of the output signal of the amplifier circuit, and to which on the other hand an identifier assigned to the circuit channel has been added, said identifier being different from the identifier assigned to the other circuit channel.

Abstract: A method and apparatus are provided for serializing compact discs on which is optically readable digital information for corresponding serializing disc sleeves, and for inserting each of the serialized discs into correspondingly serialized sleeves. A laser printing device marks with a unique serial marking, each of the compact discs and a sleeve labeling device marks each of the sleeves with one of the unique serial markings. A sleeve conveyor formed of a pair of opposed endless belts of generally fixed lengths maintained under tension and in proximity to each other holds sleeves in place as the belts move along a path extending through the sleeve labeling device and a loading station. A sleeve feeder feeds unmarked sleeves onto the conveyor while a belt drive steps the belts to shift sleeves through a series of fixed sleeve positions along the path from the sleeve feeder to the sleeve labeling device and from the sleeve labeling device to the loading station, at which the belts are separated, the sleeves are opened, and discs, transported from the laser printing device are rotated above and dropped edgewise into the opened sleeves. A controller is programmed to coordinate the marking of the sleeves and discs and the operation of the sleeve conveying the disc transport, the sleeve opening and the disc inserting operations.

In another embodiment, a bank of sub-filters (601, 602) determined with reference to the conventional matched filter (401) for CDMA is employed to demodulate the channel signal. In yet another embodiment, the output of a conventional matched filter is oversampled to demodulate  the channel signal. Each embodiment utilizes a set of adaptive coefficients selected to minimize the mean square error between the transmitted symbol and detected symbol.

Abstract: L'invention se rapporte à des formulations administrées par voie parentérale stables de busulfan qui peuvent être administrées sans risque par voie parentérale. On a mis au point un dosage par chromatographie liquide à haute performance, suffisamment sensible, de busulfan afin de quantifier précisément des concentrations dans le plasma aussi faibles que 100 ng/ml approximativement. On a étudié la stabilité de ces formulations afin de sélectionner des préparations ayant des paramètres désirables pharmacocinétiques dans le plasma pour une administration parentérale/orale. De plus, on a mis au point une technologie d'extraction quantitative en vue d'obtenir une quantification fiable du busulfan dans des échantillons de plasma après administration à la fois orale et parentérale du médicament. Lorsqu'elle a été administrée à des animaux d'expérimentation, la formulation du busulfan administré par voie parentérale, a généré des concentrations de médicaments dans le plasma bien plus importantes et a formé une zone sous le plasma bien plus importante, par rapport au temps, que la préparation sous forme de comprimés, administrés par voie orale (standard). La biodisponibilité améliorée de la formulation de busulfan administré par voie parentérale optimise la thérapie consistant à administrer du busulfan à haute dose afin de traiter les infections malignes, et améliore l'innocuité de cette thérapie.

Abstract: An automated demolding apparatus for mechanically separating contact lens mold portions of a mold assembly. The mold assembly includes a first front mold portion having a central mold section with a surrounding flange, and a corresponding second back mold portion also having a central mold section with a surrounding flange, with a molded contact lens being formed between the front and back mold portions. The demolding apparatus includes restraining fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the first mold portion. A separating fixture includes separating fingers positioned between and on opposite sides of the spaced flanges of the first and second mold portions and against the flange of the second mold portion. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the heated second mold portion relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the mold portions, while leaving the lens in the first mold portion. During demolding, the separating fixture is subjected to a substantially vertical prying motion relative to the restraining fingers to separate the second mold portion from the first mold portion.

Abstract: An improvement in a continuous process for making high internal phase emulsions that are typically polymerized to provide microporous, open-celled polymeric foam materials capable of absorbing aqueous fluids, especially aqueous body fluids such as urine. The improvement involves recirculating a portion (about 50 % or less) of the emulsion withdrawn from the dynamic mixing zone of this continuous process. This increases the uniformity of the emulsion ultimately obtained from this continuous process in terms of having the water droplets homogeneously dispersed in the oil phase. This also improves the stability of the HIPE and expands the temperature range for pouring and curing this HIPE during subsequent emulsion polymerization.
