Patent CA-2096637-A1 (CA)
Title: Control of fruit ripening and senescence in plants
Inventor: KLEE HARRY J
IPC: C12N9/88
Filed: 1991-12-17
Abstract: A method for controlling the ripening of fruits and vegetables as well as a method for controlling senescence of plant tissue is described. The method generally embraces the expression of an ACC  metabolizing enzyme in the fruit or other desired plant tissue to inhibit the production of ethylene in the fruit or plant tissue.  The use of the ACC metabolizing enzyme ACC deaminase is described in detail. The ripening or senescence process in the fruit or plant tissue is inhibited by the expression of the ACC deaminase gene such that the shelf-life and marketability of the fruit or plant is enhanced. The ACC metabolizing enzyme may be used in combination with other methods for reducing ethylene production in transformed plants to further reduce the production of ethylene in the fruit or plant. DNA constructs containing the ACC deaminase gene are also described.

Title: Automated hemodialysis chemical treatment system
Inventor: LINDSAY EDWARD R
IPC: A61M1/16
Filed: 1992-11-12
Abstract: An improved chemical treatment system (10) for hemo-dialysis machines, which in-cludes a first three way valve (26) which has a normally open position in the dialysis and rin-sing modes of the hemodialysis machine. The valve in the nor-mally open position couples a source of water (12) through the valve to the bicarbonate pump < 1 M G > (66) for rinsing purposes before and after dialysis and the chem-ical treatment modes of the he-modialysis machine. In the chemical treatment mode of the hemodiaiysis machine the valve is switched to couple a source (90) of treatment chemical through the valve to the bicarb-onate pump. The chemical treatment system includes a sec-ond valve (78), which if in the normally open .position, then only the bicarbonate portion and associated downstream portions will be chemically treated. In the closed position, the chemical will be switched to also flow through the whole hemodialysis machine from the water inlet to pro-vide for a half or total system chemical treatment cycle. A vent valve (98) coupled to the first valve can be included to further en-sure that chemicals are not inadvertently entered into the hemodialysis machine.

Patent CA-2100047-A1 (CA)
Inventor: FUJI HIROSHI
IPC: G11B7/126
Filed: 1993-07-07
Abstract: A first control data generating circuit continuously controls an output light-intensity of a light source with respect to an optical disk that has not been formatted. A second control data generating circuit controls the output light-intensity of the light source at each of a plurality of sectors with respect to an optical disk that has been formatted.  A discrimination circuit discriminates whether or not the optical disk has been formatted according to a detection of a header of each sector. According to a result of the discrimination circuit, a switch alley switches controlling operations between the first light-intensity controlling operation and the second light-intensity controlling operation.  The difference between those two types of controlling operations lies in whether timing for controlling the light-intensity is dependent on each sector or not.  Therefore, independent of whether or not the optical disk has been formatted, the light-intensity control device of the present invention makes it possible to determine an optimum output light-intensity by similar controlling operations.

Title: Method for cleaning rolls and cleaning apparatus for rolls
Inventor: AHVENNIEMI VESA
IPC: B08B3/02
Filed: 1993-11-02
Abstract: [57] Abstract A method and apparatus is described herein for cleaning the surface of a backing roll in a coater or a calender roll. The roll (1) is cleaned by injecting steam from a steam injection chamber (14) against the roll surface at a 15° angle counter to the rotational direction of the roll. Steam impinging on the surface performs effective removal of accumulated dirt and the detached dirt is carried away on the web without a deleterious effect on the quality of the web. Steam injected against the roll (1) is vacuumed away from the roll surface via a suction chamber (18), whereby the cleaning steam is prevented from escaping to the surroundings.            (Fig. 1)

Filed: 1992-09-29
Abstract: A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20 °C but is not a solvent at 20 °C (though it is at 215 °C) for polyethylene terephthalate. The last-named is a crystallisable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.

Title: Telecommunication system and a main station and a substation for use in such a system
Inventor: GRINSVEN PETRUS AUGUSTINUS VAN
IPC: H04B10/272
Filed: 1994-03-11
Abstract: ABSTRACT: "A telecommunication system and a main station and a substation for use in such a system"     Telecommunication systems such as PON-FITL-Systems are known with a TDMA frame structure comprising a main station (2) and a number of substations (4 to 7). From the International Application WO 91/08623 a system (1) is known system comprising means for coarse ranging and means for fine ranging the substations (4 to 7). For achieving accurate fine ranging an A/D-converter (29) for acquiring samples from a ranging pulse transmitted from the substation (4 to 7) is operated at a frequency which is high with respect to the master or bit clock, i.e. real time oversampling occurs. Such high speed A/D-converters are expensive, consume much power and have limited resolution. Furthermore for systems with even higher bit rates the knownoversampling becomes cumbersome. A quasi-oversampled coarse and/or fine ranging (28) is proposed operating at relatively low sampling rates. To this end the substations (4 to 7) send a repetitive ranging-bit-pattern (RBP) which is sampled in the main station (2) and thereafter reconstructed with processing means (32) to a quasi-oversampled ranging-bit-pattern. For finding a ranging error to be sent to the relevant substation (4 to 7), the quasi-oversampled ranging-bit-pattern is matched against a reference pattern, the ranging error to be found from the best match.

Title: Time-of-flight mass-spectrometer with gasphase ion source, with high sensitivity and large dynamic range
Inventor: BERGMANN THORALD
IPC: H01J27/02
Filed: 1994-06-30
Abstract: Abstract A high particle density in the extraction volume of a gasphase ion source and simultaneously a very low particle density in the driftspace of the time-of-flight mass-spectrometer are necessary for high sensitivity and a large dynamic range of the mass-spectrometer signal output.   This can be achieved by separating the time-of-flight mass-spectro-meter into two or more regions of different pressure, connecting the dif-ferent regions by gas flow restrictions. A maximum particle density in the extraction volume and simultaneously a minimal particle density in drift space can be achieved by integrating the gas flow restrictions(3,6) directly into the electrodes(1,2) of the ion source.
