Title: Reloadable ink-ribbon cartridge for typewriters or office machines of similar design
Inventor: BEHRENS ROLF ING GRAD
IPC: B41J32/00
Filed: 1987-11-06
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar design are subject to different design requirements, the intention being, above all, for them to be easily exchangeable by means of one-hand operation. Since, furthermore, the ink-ribbon cartridges are designed as disposable parts, many still functional individual parts are also thrown away. In order to avoid this, ink-ribbon cartridges having exchangeable ink-ribbon spools are known. The invention is based on the object of providing a reloadable ink-ribbon cartridge, in which it is possible to exchange the ink-ribbon spools (4, 5) with few manipulations. In this case, removing the used ink-ribbon spools (4, 5) is to be possible without soiling the fingers. This object is achieved in that the receiving spool (5) and the feed spool (4) are arranged so that they can be fitted freely onto bearing journals (11, 12) in the bottom part (6), and in that the movable parts for guiding and transporting the ink ribbon (8) are mounted on one side in the bottom part (6) of cup-shaped design and, apart from the receiving spool (5) and feed spool (4) which can be fitted freely onto the bearing journals (11, 12), are arranged so that they can be retained against dropping out of the cartridge housing when the lid (2) is opened. This makes exchanging the ink-ribbon spools (4, 5) possible with few manipulations without the operator carrying out this exchange soiling his/her fingers during this process. The exchange of the ink-ribbon spool (4, 5) is also ... Original abstract incomplete. <IMAGE>

Title: Longitudinally beaded covering mat assembly
Inventor: SCHAEFER BERND
IPC: E21D11/15
Filed: 1987-12-15
Abstract: The storage, transport and installation of covering mats for headway support under ground in mining and tunnel construction is essentially simplified or reduced by making use of covering mats without hooks formed on the head sides. The connection of these covering mats takes place by edgings and/or beads which run in the longitudinal direction being provided in the grid surface, a locking element being inserted into and fixed in the openings formed between the longitudinal bars running in two planes and the correspondingly bent transverse bars. This type of covering mat or of covering mat assembly formed therefrom is virtually no longer bound to the construction distance, i.e. such a mat can, in the same design, be used for different construction distances. Moreover, the stability of such mats is essentially increased and the connection is made safer and easier and in a manner which makes possible a continuous interlocking construction even when using support arches and a completely prepared roof screen thereon with interlocking mats. The locking elements are in each case introduced into the openings formed by the mutually overlapping covering mats, the locking element in each case being arranged in the first opening, seen in the direction of the site facing, to achieve an advantageous forepoling. By corresponding shaping of the locking element or by using a number of bars as a locking element as well as by shaping the ... Original abstract incomplete. <IMAGE>

Title: Light-valve line made of an electrooptical substrate and method for its production
Inventor: SPRINGER JOHANN DR RER NAT
IPC: G02F1/055
Filed: 1988-05-21
Abstract: Light-valve lines made of electrooptical lead-lanthanum-zirconate-titanate (PLZT) ceramic show an undesired reduction of the switching contrast during the operational period. This reduction of the switching contrast is brought about by ageing effects which have their cause in a strong concentration of electrical fields at the edges of the electrodes. For the reduction of high electrical field strengths, it is proposed to provide the surface of the PLZT ceramic with an electrically conductive layer, or to increase the conductivity of the volume region of the substate lying under the electrodes with respect to the material lying under the lightvalve. <IMAGE>

Title: Combined gas- and steam-turbine power station having pressure-charged fluidised-bed combustion
Inventor: BEULE ERHARD
IPC: F01K23/06
Filed: 1988-05-25
Abstract: In a combined gas- and steam-turbine power station having pressure-charged fluidised-bed combustion, in order to achieve a good efficiency, as high as possible a turbine inlet temperature is necessary. For the purpose of reliable operation of the gas turbine, however, a highly effective dedusting of the flue gas is necessary, which can be carried out reliably only at lower temperatures. The novel method functions with a circulating, pressure-charged fluidised-bed combustion system (11-14) and an integrated coal gasification system (50-60) for generating fuel gas. After effective dedusting (23), the flue gas from the fluidised-bed combustion is mixed with by-pass air (5), heated in a heat exchanger (15) of the fluidised-bed combustion to approximately 750@C, heated to approximately 1100@C in a combustion chamber (25) by combustion of fuel gas (26) from the coal gasification, and subsequently expanded in the gas turbine (2) while giving off energy. In a steam generator (16, 20, 35), high-pressure steam is generated, which is used for driving a steam turbine (39). With the aid of a heat-transfer circuit (70), waste heat (52, 56) from the coal gasification is incorporated with an optimum efficiency into the steam generator system (73, 74). The method is used for generating electrical energy from solid fuel with a high degree of conversion. <IMAGE>
