Title: Active frequency diplexer
Inventor: MILITZ UWE
IPC: H03H11/34
Filed: 1988-01-30
Abstract: The invention is based on the object of developing known active frequency diplexers further in such a manner that an amplifer for a higher frequency range with as large a series capacitance as possible can be coupled in without this resulting in greater impairment for the frequencies of a lower frequency range. Furthermore, large-signal distortions which are produced by simultaneous contribution of signals from the lower and upper frequency ranges should be negligibly small. In addition, the circuit complexity required for implementing the active frequency diplexer should be as little as possible. The solution of the present object consists in that the base point of the antenna (A) is connected to the input of the FM amplifier (V1) by a series circuit of three capacitors (C1, C2, C3). In addition, the base point is connected to the gate electrode (G) of a field-effect transistor (FET) by the first capacitor (C1) and a first inductance (L1) connected in series therewith. Finally, the base point is also connected to the source electrode (S) of the field-effect transistor via the first and second capacitors (C1, C2) and a second inductance (L2) connected in series therewith and to the input of the LMS amplifier (V2) and via a resistor (R2) to earth. A preferred field of application for the active frequency diplexer according to the invention are active antennas for motor vehicles. The drawing shows a circuit diagram of the...

Title: Circuit arrangement for the automatic control of test assemblies, which can be combined with manual control
Inventor: FONODI JANOS DIPL ING
IPC: H04Q9/00
Filed: 1988-03-09
Abstract: The invention relates to means for signal recognition. In this case, a Read Only Memory (ROM) is used, which preferably can be programmed and receives remote control signals via the address inputs. One of its output signals selects the signal processing unit (I, II, III) to be activated corresponding to the input command, or the quality of the operational command to be emitted, the other output signal controls the choice of that measurement channel (or those measurement channels) to which the command which has arrived is to be routed. The stage (12, 22, 32) which generates the operational commands is provided with parallel inputs for receiving remote control signals and an input for receiving control signals which have been manually generated by means of a keyboard (10) or a control signal transmitter (33). <IMAGE>

Title: Table, in particular for VDU-based workstations
Inventor: PONTOPPIDAN ESKILD
IPC: A47B9/02
Filed: 1988-05-19
Abstract: The invention relates to a table with a height-adjustable table top having at least one vertical guide member and a table frame, a spring leg being arranged between the table frame and the height-adjustable table elements. The spring leg is, on the one hand, articulated to the guide member and, on the other hand, supported against a curved rail. The supported spring end is movable on the curved rail and lockable in positions adapted to different loads of the table top. The curved course of the curved rail is selected such that at each positioning of the supported spring end the vertical force components acting in the guide member are of equal size at least in both end positions of the table top. Consequently, for each load of the table top equilibrium is achieved in each height position after setting of the spring leg has been effected. <IMAGE>

IPC: B60C29/00
Filed: 1988-06-04
Abstract: The invention relates to a vehicle wheel with a valve with non-return mechanism, the pneumatic tyre of the vehicle wheel allowing relatively long distances to be covered at reduced speed of travel even when running without air pressure after a puncture. In order to prevent incorrect refilling of such a vehicle wheel after a journey has been made with a puncture, it is proposed according to the invention that the valve have a mechanism, pneumatically parallel to the non-return mechanism, for preventing such misuse, which mechanism is fitted in the closed position and at the onset of emergency running moves into its open position and can only be closed again by means of a special tool and/or special replacement parts.

Title: Wave power-station, mounted on a ship, which transmits the up and down movement of the waves, via a single-cylinder oil-hydraulic pump, to an oil-hydraulic motor which drives the generator
Inventor: HUSNIK FRANZ
IPC: F03B13/18
Filed: 1988-08-01
Abstract: A ship which has been taken out of service is suitable for the setting-up of a wave power-station when the said ship is equipped with at least two, in the present case, however, with four guide tubes which run obliquely upwardly from below, the guide tubes being fastened with their end flanges on the keel and on the deck platform. Mounted in the interior of the guide tubes are in each case two roller guides through which likewise guide rods pass obliquely, which guide rods are anchored below the ship in a thick concrete layer. Provided on the upper end are mountings, to the ends of which, on the left-hand side and the right-hand side, is connected in each case one single-cylinder oil-hydraulic pump by means of its piston rod, the cylinders belonging to the single-cylinder oil-hydraulic pumps being mounted obliquely on the deck. Located on the cylinder are four connections for the oil-suction and pressure lines which are provided with non-return valves which always make the oil flow possible in only one direction. As a result of the waves, every up and down movement of the ship is used for suction and pressing of the cylinder. The suction takes place from an oil tank, the pressing leads to the oil-hydraulic motor which operates the generator, the oil flows from the oil-hydraulic motor back into the oil tank and is subjected to continuous circulation.

Title: Construction kit for a flue gas duct
Inventor: KUEGEL KONRAD
IPC: F24B13/00
Filed: 1989-04-25
Abstract: There exists a construction kit in which differently shaped mouldings 1, 2, 4, 5 provided with groove 9, 12, 14 and tongue are provided. In this case, it is desirable for the manufacture of the construction kit to be more economical, in that the number of different mouldings provided with groove and tongue is reduced and the adaptation of the mouldings to different cross-sectional dimensions of the flue gas duct is simplified. This is achieved in that the construction kit comprises normal panels 1 which are free from grooves and, at the transverse edges, from tapered tongues, grooved side panels 2 which at both flat sides 8, parallel to both longitudinal edges 10, have in each case one groove 9, and grooved corner panels 5 which at both flat sides 8, parallel to both longitudinal edges 10 and parallel to one transverse edge 13, have in each case one groove 9, 14, and in that the grooves 9, 12, 14 are of equal width and also have a width which is suitable for receiving the normal panels 1, grooved side panels 2 and grooved corner panels 5. In this construction kit, only four different mouldings are provided and the normal panel, present in various dimensions, is utilised. <IMAGE>
