Patent EP-0579289-A2 (EP)
IPC: C01B32/40
Filed: 1988-11-14
Abstract: A gas mixture comprising at least three components (e.g. hydrogen, carbon monoxide and carbon dioxide) is separated into three different fractions by pressure swing adsorption. A cycle of operations is performed including the step of passing the gas mixture through a first bed 210 of adsorbent and then a second bed 217 of adsorbent in series with the first bed 210. Both the beds comprise an adsorbent on which a second component (e.g. (O)) of the mixture is more strongly adsorbed than a first component (e.g. H₂) but less strongly adsorbed than a third component (e.g. CO₂). A first fraction enriched in the first component is withdrawn from the downstream end of the second bed 217. Admission of the gas mixture to the first bed 210 is stopped. A second fraction enriched in the second component is withdrawn from the upstream end of the second bed 217 and 236. A third fraction enriched in the third component is withdrawn from the upstream end of the first bed. There are typically four pairs of beds 210 and 217 in parallel with one another.

Abstract: The invention involves a method for making Bragg gratings in glass optical fibers, or other glass optical waveguides (10), which is relatively insensitive to perturbations in the actinic light used for processing. This method is suitable for mass production and lends itself well to the manufacturing environment. The inventive method involves first providing an optical phase grating (20). An interference pattern is generated by impinging a single fight beam (30) on the grating. The optical waveguide to be processed is exposed to this interference pattern, leading to the formation of a Bragg grating in the waveguide.

Abstract: An existing cellular system (X-system 102) is interconnected with another cellular system (M-system 101) via inter-office trunks (150) to add additional switching capacity for providing telephone coverage to mobiles located throughout their common coverage area. X-system (102) includes a control terminal (120) coupled by data and voice lines to base sites (121-124) and by out trunks to a telephone central office (110). M-system (101) includes a control terminal (420) coupled by data and voice lines to base sites (411-415) and by in trunks and out trunks to the telephone central office (110). M-system base sites (411-414) are colocated with corresponding existing X-system base sites (121-124).

Abstract: In the transmission of digital television signals using the COFDM method, the individual carrier frequencies used therein are phase-modulated. A phase reference signal is transmitted in each transmission frame in order to demodulate the individual carrier frequencies in the receiver. The phase difference between the phase reference signal and the individual carrier frequencies received in the same transmission frame contains the transmitted information. A problem lies in the phase and amplitude distortion of the individual carrier frequencies which can be caused by transmitter and receiver modules and by the transmission path. The novel method enables correction of these distortions, insofar as a mathematical model can be indicated therefor. To correct the phase of the received individual carrier frequencies, a mathematical model is built for the phase distortions of the phase reference signals dependent on time. The data signals received between two phase reference signals are corrected on the basis of this mathematical model of the temporal pattern of the reference phase. In order to eliminate additional random phase distortions, a maximum likelihood decision is made with the corrected phase value. The amplitude of the individual carrier frequencies is corrected using a standard amplitude value which is derived from the amplitudes of previously received individual carrier frequencies. The novel method enables the correction of phase-modulated individual carrier frequencies and can be used in transmissions based on the COFDM method. <IMAGE>

Abstract: A video coding apparatus receives a video signal containing moving-picture information, together with other information present in certain horizontal scanning lines in the vertical blanking intervals. The video coding apparatus compresses the moving-picture information into a compressed digital video data stream, assembles the other information into packets, and multiplexes the packets with the compressed digital video data stream to generate an output signal. A video decoding apparatus demultiplexes this signal to separate the packets from the compressed digital video data stream, decompresses the compressed digital video data, and outputs a video signal having information obtained from the packets in certain horizontal scanning lines in the vertical blanking intervals, and decompressed moving-picture information in other horizontal scanning lines.

Abstract: A digital printer of the present invention employs a single laser prepress unit. In a prepress process, an impression cylinder 11 is used as a plate retention member for holding four printing plates. Image formation on the four printing plates held on the impression cylinder 11 is achieved by means of the single laser prepress unit 13 disposed adjacent to the periphery of the impression cylinder 11. The printing plates thus prepressed are transported from the impression cylinder 11 to plate cylinders 17. After the printing plates are mounted on the plate cylinders 17, a printing sheet is fed from a sheet feeding section 25 to the impression cylinder 11 via a loading unit 26. On the other hand, dampening water and color inks are supplied to the plate cylinders 17 from dampening water units 18 and inking units 19, respectively. The inks are respectively transferred onto blanket cylinders 16 from the plate cylinder 17, and further transferred from the blanket cylinders 16 onto the printing sheet on the impression cylinder 11.

Abstract: Disclosed are methods and associated devices for minimizing the undesirable affects of interference signals in the upstream spectrum of an multiuser interactive system. The method comprises receiving an initial upstream signal at a multiuser interactive processor in a multiuser interactive system. The frequency of the initial upstream signal is at a frequency within the upstream spectrum. Next, the multiuser interactive processor determines a measure of interference associated with at least a portion of the upstream spectrum. Based upon the measure of interference, an upstream channel, from within the upstream spectrum, is selected. The upstream channel is within the upstream spectrum. Finally, the multiuser interactive processor transmits a second signal representative of the upstream channel.

Abstract: A sensor mount apparatus includes a loop for carrying a sensor payload. An upper portion of the loop includes at least one upper attachment point for receiving at least one upper tether line. A lower portion of the loop includes at least one lower attachment point to connect the sensor mount apparatus to a lower tether line. The sensor mount apparatus further includes an upper plate mounted to the loop, a lower plate for carrying a sensor payload, and a slide mechanism mounted between the two plates. The slide mechanism operates to slidably move the lower plate relative to the upper plate so that the lower plate and sensor payload attached to the lower plate move to a position where the sensing device of the sensor payload is not obstructed by the loop. Where the sensor payload is an optical sensor, such as a camera, the camera may be positioned to see an unobstructed, three hundred sixty degree field of view. A free mount arrangement between the upper plate and the loop reduces sensor performance degradation when the loop is under stress.
