Title: Directional coupler branch
Inventor: WENDEL WOLFGANG DIPL ING
IPC: H03H7/46
Filed: 1983-06-18
Abstract: The invention relates to a directional coupler branch for transmission of a lower and of an upper frequency range, the directional coupler being effective in the upper frequency range only, with a voltage and a current transformer, a capacitor inserted in each case between the primary winding of the voltage transformer or the secondary winding of the current transformer and earth, which capacitor represents a short circuit for the upper frequency range and, together with the inductance of the associated transformer winding, forms a series resonant circuit whose resonant frequency lies between the lower and the upper frequency range, and a resistance network to produce the branch attenuation in the lower frequency range, which forms the internal directional coupler terminal resistance for the upper frequency range. To improve branch adaptation, feedback effects on the main circuit in the event of failed termination of the branch and branch attenuation even with high-impedance termination of the branch with minimum component costs, only two resistors are provided for the resistance network which are inserted in the directional coupler branch in such a way that they are connected in parallel for the upper frequency range and form a voltage divider for the lower frequency range.

Title: Fuel injection pump for internal combustion engines
Inventor: HABERLAND SIEGFRIED
IPC: F02D1/18
Filed: 1983-11-09
Abstract: A fuel injection pump is proposed which is supplied with fuel by a fuel feed pump (4) driven synchronously with the fuel injection pump, the pressure of which feed pump at the same time serves as control pressure for adjusting the beginning of injection. For adjustment of the pressure a pressure control valve (10) is provided in a known manner to which a limiting cross-section (21) is connected on the output side, it being possible to circumvent this limiting cross-section (21) as a function of the speed by way of a bypass relief line (26) and under the control of a control value control valve (22). In this way a graduation and/or adaptation of the control pressure curve on the pressure side of the fuel feed pump (7) can be achieved and thereby an adaptation of the injection timing by way of the speed. <IMAGE>

Title: Single-sheet feed device for a typewriter or similar office machine, having two supply containers
Inventor: HANENKAMP HORST
IPC: B41J13/036
Filed: 1983-12-03
Abstract: Modern single-sheet feed devices have at least two supply containers (6, 7), in each of which a supply pile (3, 4) of individual sheets (2) of different size is arranged. In this case, separating rollers (8, 9) which engage frictionally on the supply piles (3, 4) can be coupled selectively via couplings (10, 11) to a gear mechanism which can be driven by the platen (12). The invention is based on the object of simplifying the drawing-off of the individual sheets (2) from the supply piles (3, 4). According to the invention, this is achieved in that a control member (45) can be driven by a cam (51) and has a trip latch (44) mounted pivotably thereon, which trip latch can be moved with its trip projection (43) selectively in front of one of the carrier edges (60, 73) of the two pawls (29, 37) for the couplings (10, 11) to release them. As a result, reliable selection of the single sheet is possible at any time by simple means. <IMAGE>

Title: Fluidised-bed furnace
Inventor: WIESER RUDOLF DR
IPC: F23C10/02
Filed: 1984-04-26
Abstract: The inventive proposal relates to a fluidised-bed furnace of small to medium size which, to improve the fuel combustion and SO2 binding, is equipped with one or more separator cyclones for ash and lime dust or dolomite dust. The recycling of ash and lime dust or dolomite dust into the fluidised bed is carried out via these separator cyclones. The ash separator cyclones, to achieve a space-saving construction, are either integrated in the upper part of the combustion chamber or are arranged in a rotationally symmetric manner outside on the combustion chamber casing. To increase the purity of the flame, the separator cyclones can also be connected on the furnace gas side in a two- or three-stage manner one after the other. For the combustion of high heating value fuels, the combustion chamber casing is advantageously formed from double tubes welded together which can be particularly easily cleaned. Since the novel fluidised-bed furnace delivers a particularly clean flame gas, it can also advantageously be connected upstream of flame tube boilers and water tube boilers. The novel fluidised-bed furnace, in a special design, can also be operated with furnace-gas-side supercharging and be assigned to a gas turbine. <IMAGE>
