Patent DE-3338878-A1 (DE)
Title: Circuit for 0 DEG power combination of two RF power amplifier arrangements
Inventor: MOLIERE THOMAS DIPL ING
IPC: H03H7/48
Filed: 1983-10-26
Abstract: In power amplifier arrangements designed with semiconductor elements, in particular output stages of short-wave transmitters, two or more amplifier output stages must, in order to maintain the required output power, be operated in parallel and be combined on the output side via hybrid circuits (GS) to form the common output. The balancing resistor (RN) which absorbs RF power in the event of unbalanced loading of the hybrid circuit must be cooled by means of a heat sink. As a result of this fact in particular, the balancing resistor at RF potential has a relatively high capacitance to earth which, in terms of reducing the upper limit frequency of the power output stages connected to the hybrid circuit, loads the terminals of these power output stages in an undesirable manner. To remedy this, it is proposed to connect the balancing resistor via an isolating transformer (ÜN), designed with low capacitance, to the hybrid circuit terminal assigned to it. <IMAGE>

Title: Method for controlling the power of the heat source of a soldering device
Inventor: OHLE ECKARD DIPL ING
IPC: B23K3/047
Filed: 1984-02-11
Abstract: A method is proposed for controlling the power of the heat source (1 and 40 respectively) of a soldering device with automatic infeed of a certain length of soldering wire to be melted to the soldering location (2, 3 and 34 respectively) during each soldering operation, in which method the time between the landing of the soldering wire (5, 7 and 29, 33 respectively) on the soldering location (2, 3 and 34 respectively) and the melting away of the predetermined length of wire is measured and evaluated to control the power of the heat source (1 and 40 respectively). This makes it possible to keep the soldering time constant at all times, even if the soldering parameters change. <IMAGE>

Title: Device for cooling agricultural bulk goods, preferably grain
Inventor: REISINGER LUDWIG
IPC: F24F1/0035
Filed: 1984-03-14
Abstract: The device for cooling agricultural bulk goods, preferably grain, to a temperature which is lower than the outside temperature consists of a blower (4) which draws outside air through an air inlet (1), a cooler (2), a system of air ducts (3, 10) which connects the air inlet (1) to the cold-air outlet (5), and of a connecting duct (6) which bridges the cooler (2) and the blower (4) and the duct (3) and in which an air flap (7) serving for regulating the cold-air temperature is inserted. If the outside temperature and thus the temperature of the air drawn in rises to such an extent that the installed cooling capacity is no longer sufficient to cool the entire air quantity flow sufficiently far so that the temperature at the temperature sensor (8) rises above the set desired value, then the air flap (7) is controlled in small steps in the open direction via a conventional control system. As a result, cold air can flow via the connecting duct (6), where it mixes with the fresh air drawn in, and the cooling system is given the impression that the outside temperature has fallen. This control process is continued until the set desired temperature value is again reached at the temperature sensor (8). With the aid of this device, the air quantity flow can be controlled according to the desired cold-air temperature without having to throttle the blower for this. <IMAGE>

Title: Lens arrangement having a variable focal length
Inventor: NEIL IAIN ALEXANDER
IPC: G02B13/14
Filed: 1984-06-02
Abstract: The lens arrangement (11) serves for use in a refracting telescope (10) having an eyepiece (12), and consists of three lenses E, F and G, of which the lenses E and G are individual lenses, while the lens F is a triplet. The lens G is rigidly mounted on a support (20), while the lenses F and E are mounted axially displaceably on carriages (21, 22), which are driven by an electric motor (23, 25). The motors are controlled by a computer (28) which is preprogrammed by means of data which specify for the prescribed structure of the lens arrangement (11) the dependence of the positions of the lenses (E and F) on the focal length and amplification at the prescribed temperature for the purpose of achieving the best possible optical resolution. The desired focal length and amplification are input into the computer by hand using control devices (30, 32). The temperature prevailing in the lens arrangement (11) is continuously monitored by a measuring sensor (34) and input by the latter directly into the computer (28).

Patent DE-3427083-A1 (DE)
Title: Stone-picking appliance
Inventor: ZIMMER ROLAND
IPC: A01B43/00
Filed: 1984-07-18
Abstract: The stone-picking appliance described here is a tractor-mounted appliance for the fully mechanised removal of stones from earth and arable soil. The appliance is designed so that the lateral frame part 13 and the cutter bar 15 produce a kind of box coulter by which the earth is picked up. The earth masses picked up and containing stones are then taken up by the rotating sweeping rollers 12 and transported rearwards over a vibrating grid 7 and 8. Two or more sweeping rollers (steel-wire brushes), as required, can be arranged in succession. In order to break up hard lumps of soil, pounding elements (steel tines) can be attached to the sweeping rollers. During transport over the vibrating grid, the small parts fall back onto the arable soil and the larger constituents (stones), which cannot fall through the grid, are transported by the same sweeping rollers into the rear integrated stone-collecting container which has a hinged grid for emptying. The obliquely rearward-ascending arrangement of the front grid part is necessary in order to obtain ground clearance between the grid and earth. The collected stones can move in the dimensions of between 10 and 50 mm, at most 140 mm. <IMAGE>

Patent DE-3429924-A1 (DE)
Title: Method for testing a device ready for operation
Inventor: SCHWEYER HERMANN
IPC: H04Q1/24
Filed: 1984-08-14
Abstract: The device can be the time-division multiplex switching network (ZMK) of a digital telephone switching device (ZV). This can be connected via appropriately constructed connectors (SV) to a processor-controlled test device (PE) carrying out the test. It is intended to prevent any changes from occurring in the connections existing between the hardware parts in the completely equipped device under test. For the comparison of a nominal signal sequence with the actual signal sequence which can be picked up at a correspondingly selected circuit point, which comparison forms the basis of the test, the digital nominal signal sequence is therefore picked up at a suitable circuit point and supplied to the test device in cases in which this nominal signal sequence cannot be directly provided by the test device for reasons of an undisturbed sequence. In the case of the digital switching device, the digital signal sequence is used which is produced at the output of the analog/digital converter (Co) on the basis of the analog input information supplied to it. This ensures that no undefined signal state exists for the respective input chip of the switching network to be tested. At the same time, this makes it possible to eliminate inadmissible heating of the output stages of the said converter. <IMAGE>

Title: Graphite fibres, and process for their production
Inventor: NELSON DANIEL C
IPC: C04B14/38
Filed: 1985-03-04
Abstract: The invention describes a novel oxidation-resistant graphite-fibre product in the form of a graphite fibre having a thin coating of a ceramic material, either based on silicon or based on a combination of silicon and boron, which promotes and improves the use of the fibre product in ceramic composite materials. The process for the production of this fibre product proposes coating a carbonised graphite precursor fibre, typically a polyacrylonitrile material, with a polyorganosilicone, such as, for example, polyorganosilane, or a combination of a polyorganosilicone and a boron precursor, such as, for example, an alkyl borate. The graphite precursor fibres with coating are then pyrolised together in a non-oxidising atmosphere.

Title: Method and appliance for operating a lead-acid battery having electrodes with electrolyte flowing through them
Inventor: BORGER WALDEMAR DIPL CHEM DR
IPC: H01M50/77
Filed: 1985-08-20
Abstract: In order to optimise the energy density of a lead-acid battery (1) having electrodes with electrolyte flowing through them, only that amount of electrolyte is fed to the battery from a reservoir (4) by means of a pump (5), which, based on the active mass, is required for the current yield to be expected under practical discharge conditions, and whose once-through throughflow is regulated in such a way that the concentration of the depleted acid discharged from the electrodes remains approximately constant. To this end, a concentration sensor (7) immersed in the acid discharge (6) signals its measured values to a regulator (9) which controls the inflow rate by means of an inlet valve (3). Recharging is carried out at a constant cell voltage in a first phase with the electrolyte at rest, in a second phase with intermittent flow through the electrodes, utilising the acid depleted during discharge and collected in the vessel (10). Via route (11, 2) the acid, if the three-way valves (12, 13) are set accordingly, reaches the battery and, after charging has been completed, returns to the reservoir (4) as regenerated acid via the route (11, 2, 14). <IMAGE>
