Granted: 1987-01-02
Abstract: An ink fountain, incorporating individually regulated metering segments, for a printing machine, comprises a vat containing ink and delimited, on one side, by a horizontal inking roller. The upper edges of the metering segments determine, with the peripheral surface of the inking roller, gaps of widths adjustable as a function of the thickness of the film of ink having to be formed on the inking roller. Regulating pusher elements are mounted to slide in a body and act respectively, at their ends, on the upper parts of the individual metering segments. Each metering segment is fixed on a front face of a common support block itself removably mounted on the body, this block being pierced, in its upper part, with holes through which extend the pusher elements acting on the segments and adapted to be dismantled jointly with segments which it bears.

Abstract: A side pumped, fiber optic amplifier comprises an optical fiber (12), having a first refractive index, formed of a laser material, such as Nd:YAG. A jacket (14), which surrounds the optical fiber (12), has a second refractive index, lower than the first refractive index. This jacket (14) is cone shaped and tapers from a large end (16) to a small end (18). High power laser diodes are mounted on the large end (16) to produce collimated pump light to pump the optical fiber material. The cone shaped jacket (14) focuses this pump light to an interaction region at the small end (18), where the jacket material is quite thin, e.g. on the same order of magnitude as the diameter of the optical fiber (12). The focused light is absorbed by the optical fiber (12) in this interaction region, and causes an electronic population inversion in the laser fiber material. A signal propagating through the optical fiber (12) stimulates spontaneous emission from the optically excited laser material, thereby resulting in amplification of the signal.

Abstract: This invention relates to polyurethane(urea) compositions which contain foam and which are preferably cationically modified, contain non-abrasively bonded fillers and have a very high water absorbability (WAF). Production is effected by reacting isocyanate-terminated prepolymers with a quantity of water far exceeding the stoichiometric quantity in the presence of foams in particle or film form. The reaction mixture may also contain lignite powder and/or peat, other inorganic and organic fillers and/or biomasses (living cells, living bacteria, enzymes). The polyurethane(urea) compositions contain up to 95% by weight of foam particles and may contain further fillers (preferably lignite and/or peat). The compositions are swollen and have a high water content during production. Their water absorbability (WAF) when suspended in water is 33 to 97% by weight of water. They can be used as carriers in microbic synthesis processes for the production of complicated organic compounds (when they have incorporated biomasses) as special carriers for the growth of plants, as filter agents or as adsorbents for non water-soluble liquids [for example, crude oil or petrol].

Title: Method and device for the operation of a hvdc short interconnection in case of power system faults
Inventor: BENDL FRANZ-WOLFGANG
IPC: H02J3/36
Filed: 1986-03-14
Granted: 1989-08-03
Abstract: Upon the occurrence of a change of an a.c. voltage amplitude of an a.c. power network line in one station A, a computing element generates a first pilot control variable by means of which the control angle of the respective static converter is shifted in terms of a reduction of its d.c. output voltage. In the other station a voltage correction regulator generates a correction variable by compensating the voltage drop in the HVDC transmission line, by means of which the control voltage of the respective static converter is corrected, which, for example, is generated by a pilot control voltage and the output signal of a marginal current or extinction angle regulator. Thus, even in case of an a.c. power network fault-induced voltage dip of the HVDC voltage, a preset value can be maintained for the HVDC current and the voltage dip in the power transmission be reduced. This procedure is independent of which station is operated as rectifier and which as inverter.
