Abstract: Un génome végétal recombiné contient une cascade de gènes qui fait qu'il ne peut produire une plante mature et nécessite la présence d'un inducteur chimique. La cascade de gènes comporte une transition génique pouvant être induite par application externe d'un inducteur chimique et commandant l'expression d'un produit génique qui affecte l'expression d'un second gène dans le génome. La survie ou le développement de la plante dépend soit de l'expression, soit de la non-expression du second gène et l'application de l'inducteur détermine, par conséquent, le développement ou le non-développement de la plante. Dans un exemple, le second gène code une molécule cytoxique et l'expression de ce gène est fatale à la plante. Dans un autre exemple, le second gène code une caractéristique souhaitable que l'on peut séparer de façon sélective en appliquant ou en retirant l'inducteur chimique. On peut placer le second gène sous le contrôle d'un promoteur régulé du développement.

Abstract: A method is to be specified for inspecting, repairing or replacing tubes (2) of the bottom head (3) of a reactor pressure vessel, in which the radioactive loading is reduced considerably by means of probes (4) of inner-core instrumentation inside or outside the reactor pressure vessel. For this purpose, individual shielding vessels (6, 7, 8, 9) are installed in the reactor pressure vessel (1). A shielding vessel (9) is penetrated by shafts (17) in which water-filled cartridges (19) can be installed. In the bottom plates (10) of the remaining shielding vessels (6, 7, 8) and in the cartridge bottoms (20), tubes (15) are let in for the accommodation of the probes (4). After the removal of a cartridge (19), a carrier (22) for processing tools can be inserted into the shaft (17). <IMAGE>

Abstract: A system that produces sharper pictures by setting the lens (16,17) of a camera (13) to a closer focus position, when the flash unit (11) of the camera is set to a bounce position. In this system, the reflector and lamp of the flash unit are pivoted to direct the light produced by the flash unto an overhead ceiling. The focus position of the lens is adjusted by coupling the motion of the lamp to the motion of the lens element (16) so as to move the focus range of the lens (16,17) more nearly into the range of the bounce flash.

Abstract: The invention relates to a textile decoloriser (decolorant stripper), especially for household purposes, which in aqueous solution forms a decolorising liquor for textiles to be decolorised. It is distinguished according to the invention by a storable powder mixture with thiourea dioxide as the active decolorising component, also with sodium carbonate or some other water-soluble carbonate or bicarbonate of the alkali elements as alkali carrier and with an antifoam for removing oxygen from the decolorising liquor or with a foam preventative for preventing oxygen passing into the decolorising liquor. Preferably the mixture contains about 3 to 20-25% by weight of thiourea dioxide. The decolorising effect can surprisingly, despite the low concentration of thiourea dioxide, be improved by an addition of urea. Such a textile decoloriser is sufficiently stable and also storable, simple to handle and significantly more compatible and also gentler than hitherto customary textile decolorisers based on sodium dithionite. It possesses high decolorising effectiveness and is usable in various temperature ranges, including at room temperature.

Abstract: A monolithic, environmentally stable Mach-Zehnder device is formed by threading first and second dissimilar optical fibers through the bore of a glass tube. The tube is evacuated and heated to collapse it onto the fibers. The tube is further heated and stretched at two spaced locations to form two couplers that are joined by the two optical fibers. The fibers have different propagation constants in the region between the two couplers, whereby there is a relative delay in the optical signal propagating in one of the fibers with respect to the optical signal propagating in the other fiber.

Abstract: An optical modulating and amplifying apparatus includes an optical amplifier 3 and a modulator 4. In the apparatus, an input optical signal S1 and an excited light SP are combined with each other by an optical mixer 31 to produce an output light signal. The excited light SP from a laser diode 40 is sensed by a photodiode 41. A bias and an amplitude of the sense signal are respectively sensed by a means value sensor 51 and a modulation signal sensor 52. A modulation degree of the excited light SP is computed by a divider 54. A control signal to develop a predetermined modulation degree is delivered from a control signal generator 45 to a variable gain amplifier 43. In response to the control signal, the amplifier 43 controls the amplitude of the oscillation signal from an oscillator 44. A laser diode driver 42 adds a bias to the oscillation signal to drive the laser diode 40. The modulation degree is kept unchanged regardless of variation in an output level of the excited light so as to achieve the modulation with a high signal-to-noise ratio.

Abstract: An adjustable length ski pole (4) includes two telescopically fitted together ski pole halves (4a, 4b), and a clamp (16, 116) disposed about the joint between the two pole halves. The clamp (16, 116) includes a resilient tubular member (20, 120) having an annular sidewall (24, 124) which defines a cylindrical bore (28, 128), where the sidewall (24, 124) is formed with a longitudinally extending gap (32, 132) to allow the tubular member (20, 120) to be selectively biased to reduce the gap width and thus the diameter of the bore, or to enlarge the gap width and thus the diameter of the bore. The gap (32, 132) defines first (32a, 132a) and second (32b, 132b) opposing sidewall edges having coaxial first (34, 134) and second (36, 136) openings respectively. The clamp (16, 116) also includes a pin (40, 140) anchored at one end in the first opening to extend with the other end through the second opening, and a lever arm (48, 148) pivotally attached at one end to the other end of the pin (40, 140), to move between a clamped position, in which the lever arm (48, 148) lies in contact with the ski pole to bias the first and second sidewall edges towards one another, and an unclamped position, in which the lever arm is pivoted away from the ski pole to allow the gap (32, 132) to widen. The sidewall edge includes a camming surface (44, 144) and the lever arm (48, 148) includes a camming knuckle (62, 162) formed at said one end to contact the camming surface (44, 144) and force the second sidewall edge toward the first sidewall edge when the lever arm (48, 148) is pivoted to the clamped position, to thereby secure the two pole halves (4a, 4b) in a fixed position relative to one another.

Abstract: In a liquid ring pump having a port member (50) with at least one auxiliary gas discharge port (58a) in addition to the main gas discharge port, an auxiliary gas discharge conduit (68) is provided to extend the auxiliary gas discharge port so that a relatively large check valve (78) can be more easily provided for the auxiliary port. The auxiliary discharge conduit (68) is preferably provided in the head member of the pump, and it preferably extends away from the auxiliary port in a generally radial direction. This allows the check valve to be placed at a less congested location in the pump, which facilitates provision of a larger check valve and also access to the check valve for such purposes as maintenance of the check valve.
