Title: Interference filter with reduced half value width - contains two filters enclosing small angle and maintains transmission
Inventor: OSTER HELMUT DIPL PHYS
IPC: G02B5/28
Filed: 1980-11-03
Abstract: An optical filter arrangement with interference filters is mainly applicable to multiple component gas analysis for selective determination of individual absorption bands. The arrangement enables the half vale with width of the transmission region of a partic. type of filter to be reduced simply. Two identical plane interference filters (F1,F2) are placed one behind the other in the beam path (1) so as to enclose a small angle alpha between them of between 0 and 5 degrees. They are both inclined equally to a plane (e-e) perpendicular to the beam path. Alternatively, the two filters may be inclined to the transverse plane at different angles. The arrangement enables the half value width to be considerably reduced without reducing the transmission below a useful level.

Patent DE-3100274-A1 (DE)
Title: Thermocouple with two heads
Inventor: KOERTVELYESSY LASZLO VON DIPL
IPC: G01K7/12
Filed: 1981-01-08
Abstract: In the head of a thermocouple, the thermoelectric wires are lengthened by means of balancing lines. This produces a thermoelectric error which is larger the higher the head temperature. Again, the electronic errors of a measuring transducer are higher, and the service life is shorter, the higher the temperature of this head containing the electronic system. The two errors can be reduced if, in accordance with the invention, the thermocouple also has a second head, the temperature of which is lower. The two heads are electrically connected to one another by means of thermoelectric wires from the same roll. The advantages of the invention are that the temperature can be monitored with the first head by using a test thermocouple, and that the second head reduces the thermoelectric errors and prolongs the functioning of the electronic system and renders it more accurate.

Patent DE-3107017-A1 (DE)
Title: Voltage stabilising circuit
Inventor: MAYER HERMANN
IPC: G05F1/62
Filed: 1981-02-25
Abstract: A voltage stabilising circuit is proposed which supplies a constant output signal even with changing load and high-impedance supply voltage source. For this purpose, a capacitor is provided which is charged up by the supply voltage source. If then the voltage of the supply voltage source breaks down for a short time when a further load is added, the charged-up capacitor is connected in series with the supply voltage source. This prevents the supply voltage from dropping below a predetermined minimum voltage point. The circuit arrangement is particularly suitable for devices with electric motors or incandescent lamps which require particularly high currents for a short time when being switched on. <IMAGE>

Filed: 1981-04-03
Abstract: A plurality of contact elements (4) which are in the form of domes, are fitted in conjunction with conductor tracks or surfaces (2) alternately on both sides in the peripheral region along at least one edge (3) of the printed-circuit board (1). The apex points of said conductor tracks or surfaces (2) are located in planes (e1, e2) symmetrically with respect to the centre plane (m) of the printed-circuit board (1). A contact rail (5) is used as the mating contact element. This contact rail (5) has a U-shaped cross-section and its limbs (7), which consist of conductive material, form the edge (3) of the printed-circuit board (1). Contact rails for the longitudinal edges of the printed-circuit board (1) can at the same time carry out the function of guide rails for holding the printed-circuit board. The distance (a2) between the parallel inner surfaces of the contact rail is less than the distance (a1) between the apex point planes of the contact elements, which are arranged at such distances (a3) apart that they rest in a sprung manner on the inner surfaces of the contact rail (5), using the bending elasticity of the base material of the printed-circuit board (1). The peripheral contact-making is preferably used for the purpose of connecting the conductor surfaces (which are provided as screens against electromagnetic interference) by the shortest route to a common potential, especially earth potential. <IMAGE>

Title: Laying method for loose concrete paving stones and interlocking stones
Inventor: AUMILLER RUDOLF
IPC: E01C19/52
Filed: 1981-08-26
Abstract: The invention relates to a laying method for loose concrete paving stones and interlocking concrete stones which are produced in the laying arrangement and installed with laying devices (20). The achievement of the aim lies in preventing the individual stones separating. The aim is achieved by the laying unit being pressed with constant or intermittent recurrent counterpressure from the sand-side jaw against the already laid concrete stones during lowering, while the stone-side jaw releases the unit and sets the dead weight of the laying unit down in the sand foundation. The counterpressure can be effected with mechanical devices by human force, springs, hydraulic cylinders with air pressure or a co-sliding jaw (93). <IMAGE>

Title: Automatic apparatus for investigating liquid samples
Inventor: DRESSLER JOSEF
IPC: G01N35/10
Filed: 1981-10-30
Abstract: In an automatic apparatus for investigating liquid samples, an aliquot is taken of the sample agitated by a stirrer using a pipette, injected into a heated graphite tubular cell and subjected to incineration. At about 2700 DEG C (atomisation phase), the absorption of a light beam passed through the cell caused by the atoms of the substance to be determined is measured. In order not to falsify the samples, before a fresh sample portion is collected, the pipette is rinsed out in a solvent and adhering drops are removed by the stirrer. Evaporation of the solvent added to the samples is prevented by covering the sample carrier and saturating the atmosphere surrounding the samples with evaporated solvent.
