Abstract: A man-made vitreous fibre batt is made using two or more centrifugal spinners (1, 2, 3) arranged in side-by-side relationship by fiberising melt on the spinners and collecting the fibres on a conveyor (5) as a web, and cross-lapping the web to make a batt, wherein two or more fiberising parameters selected from the physical properties, chemical analysis, melt flow, position, acceleration field or air flow field are adjusted in order to control the thickness properties of the batt. Both the process and the apparatus is novel. By the invention it is possible to obtain a batt having differing properties in the core (12) from either or both of the face sections (10, 11).

Abstract: A process is provided for the production of a catalytically-active carbonaceous char. By this process, a nitrogen-containing compound is combined with an uncarbonized nitrogen-poor carbon-containing material. The resulting mixture is then carbonized and oxidized at temperatures less than 600° C. The resulting low-temperature char is next heated to temperatures greater than 600° C. and subsequently activated with H2O, CO2, or O2, singly or in any combination, to result in the catalytically-active carbonaceous char. The resulting catalytically-active carbonaceous char has utility for the chemical conversion of peroxides, hydrides, SOx, NOx, and chloramines in liquid and/or gaseous media.

Abstract: The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, an absorbing material is blended into the polymer so that the absorbing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the absorbing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

Abstract: A method of effecting payment with a cash card that includes an electronic purse, such as a smart card that includes a chip and with which money can be deposited in said chip. When used for payment the card is read in a pay terminal, such as a cashpoint teller or automatic teller, and the payment sum is subtracted from the amount stored in the chip. The card includes data relating to a cash card number to which the card is tied. When the card is read in the cash card reader of a pay terminal the cash card number is read and is registered to enable a cash card transaction to be carried out, and the amount available on the chip is also read and registered. The pay terminal subtracts the amount concerned from the chip only when the chip contains an amount sufficient to cover the whole of the sum concerned and remains in the cash card reader for a period of time sufficient for the transaction to be carried out. The pay terminal then erases cash card number that was registered. The pay terminal is caused to carry out a conventional cash card transaction when the chip does not contain sufficient funds to cover the whole of the amount concerned, or if it is not left in the cash card reader for a sufficient length of time.

Abstract: The present invention provides a bacterium having a genome that is genetically engineered to be at least 2 to 14% smaller than the genome of its native parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites. Thus, the methods can be used to generate a series of deletions in a bacterium without increasing the possibility of undesired homologous recombination within the genome. In addition, some of the methods provided by the present invention can also be used for replacing a region of a bacterial genome with a desired DNA sequence.

Abstract: The present invention relates to the angular calibration of passive reception systems such as sonars or active ones such as certain radars whose angular performance is inadequate. The invention proposes a method making it possible to perform antenna calibration using the detection system associated with this antenna under real operating conditions. The method according to the invention consists in making an immersed noisemaker deployed along a substantially rectilinear uniform trajectory and a submarine equipped with an antenna to be calibrated along any trajectory whatsoever, but nonrectilinear. The method according to the invention consists also in implementing a trajectography algorithm making it possible to determine the noisemaker-antenna relative distance at known instants the, and to deduce therefrom the trajectory followed by the noisemaker as well as the bearing corresponding to the positions of the noisemaker at the measurement instants. The bearing thus calculated is compared with the bearing measurements carried out directly by the sonar associated with the antenna to be calibrated. This method applies in particular to the calibration of sonar antennas during their commissioning.
