Title: Contact system for a single-column pantograph disconnector
Inventor: SCHULZ KLAUS
IPC: H01H31/36
Filed: 1983-03-01
Abstract: In a contact for a single-column pantograph disconnector, the main current contacts consist of moving pantograph contact pieces (2, 3) and a stationary mating contact piece (1). The main current contacts (1, 2 and 3) can be connected in parallel with a preliminary-contact device (6) which closes before the main current contacts (1, 2, 3) during switching on and opens after the main current contacts (1, 2, 3) during switching off. In order to achieve bounce-free switching of the preliminary-contact device (6), the preliminary contacts (7, 8) are arranged outside the contact region of the pantograph contact pieces (2, 3) on the mating contact piece (1), and are formed by a stationary laminar contact (8) and a moving switching pin (7), which can be controlled by the pantograph contact pieces (2, 3) via a pantograph lever drive (6). <IMAGE>

Title: Mirror antenna with an exciter or catchment reflector which is supported at the apex of the mirror
Inventor: DOMBEK KARL-PETER DR ING
IPC: H01Q19/13
Filed: 1983-03-09
Abstract: The invention results in a central support, which is easy to instal and has little influence on the polar diagram, of exciters or catchment reflectors of mirror antennas. To this end, the exciter or catchment reflector (1) is attached to at least two supports (3) which run outside the primary radiation over a path a towards the edge of the mirror, and which in each case form the upper limb of a two-limbed supporting arm whose lower limb is constructed as a strut (4) pointing towards the mirror apex and is rigidly connected to a short supporting tube (5) which is arranged in the vicinity of the apex of the mirror. A high moment of resistance against bending in the direction of the mirror axis is achieved if the two supporting arms (3, 4) are arranged at right angles to one another. In this case, the cross-sections of the supporting arms are provided with surface moments of resistance which are as different as possible in the two cross-sectional major axes. This leads to a small amount of electrical shading, with a high bending strength at the same time. An intermediate piece (6) running approximately parallel to the mirror axis is expediently provided between the support (3) and the strut (4). Simplified production results if the supports (3), struts (4) and, if applicable, the intermediate piece (6) consist of curved hollow profiles which approximate to the above dimension rules (Fig.). <IMAGE>

Title: Process for eliminating HCl and SO2 from flue gas
Inventor: SCHLIPPER PETER
IPC: B01D53/34
Filed: 1983-03-24
Abstract: The invention relates to a process for eliminating HCl and SO2 from flue gas using calcium carbonate and calcium hydroxide. Flue gas is essentially taken to mean that from power stations, which is discharged into the atmosphere after its purification. If a high purity is demanded, that is low residual SO2 contents of the purified gas, a procedure purely involving limestone results in high operating costs and other disadvantages. In order to design the process to be more operationally reliable and economical, HCl and SO2 are absorptively eliminated using two-stage gas scrubbing, the scrubbing liquid used in the first scrubbing stage being suspended calcium carbonate and the scrubbing liquid used in the second scrubbing stage being suspended calcium hydroxide.

IPC: G07D9/00
Filed: 1984-02-06
Abstract: The invention relates to a coin container for coins inserted upright into one or more coin troughs. In coin containers of this type which have become known hitherto, with improper treatment of the cashbox into which this coin container is inserted, for example when the cashbox drawer is pushed in somewhat too hastily, the first coin could tip out of the coin container if it is standing in the coin trough as a single coin or together with a further coin. According to the invention, a groove is provided in the first coin trough for the engagement of the first coin to be inserted. The individual coin inserted into this groove can no longer tip over, even when the cashbox is actuated with a jolt.
Patent DE-3409939-A1 (DE)
Title: Television sound demodulator
Inventor: HEINLEIN WERNER DIPL ING
IPC: H04N5/60
Filed: 1984-03-17
Abstract: Having regard to the fact that the sound signal/noise ratio is too poor in the intercarrier system, a quasi parallel-sound method with common RF mixing and subsequent separate intermediate-frequency paths for picture and sound is used. The down conversion from the first intermediate frequency to the second intermediate frequency is carried out using a freerunning oscillator tuned to the picture carrier frequency. The voltage-controlled oscillator for generating the oscillator frequency used in the first mixing stage for mixing with the RF input signal is retuned with a retuning signal generated from the third harmonic of the picture-carrier frequency. Evaluation of the third harmonic of the picture carrier frequency provides approximately 10 dB of the AFC control-loop gain without significantly increasing the noise, as a result of which the AFC control loop provides virtually no further contribution to the noise characteristic of the sound demodulator. If it is carefully dimensioned, the oscillator for driving the first mixing stage can also be made sufficiently noise-free. Its long-term drift characteristic is eliminated by the AFC circuit.

Patent DE-3423756-A1 (DE)
Title: Telescopic tube
Inventor: FLEISCHMANN HERBERT DIPL ING
IPC: F16B7/14
Filed: 1984-06-28
Abstract: In the case of a telescopic tube having an inner tube 1 and an outer tube 2, a cone 3 and a threaded piece 4 are integrally formed on the end of the outer tube which engages over the inner tube. This threaded piece 4 engages by means of a screw with a mating threaded piece 5 of a threaded collar 6 which can be operated by hand. A separate, longitudinally-split spring ring, which engages around the inner tube, is pressed into the cone by means of the mating threaded piece. In order in this case to achieve reliable axial displacement security when a typical force is applied to the screw collar, and in order to achieve a small diameter of the clamping connection, the threaded piece 4 is integrally formed on the expanded edge of the cone 3. The mating threaded piece 5 is screwed into the space between the threaded piece and the outer jacket of the inner tube 1. Located in front of the end of the mating threaded piece 5 is the spring ring 8 which encloses the inner tube, with respect to which spring ring the mating threaded piece 5 can rotate freely. The axially slotted spring ring 8 is pressed in between the cone 3 and the outer jacket of the inner tube 1, with the end 7 of the mating threaded piece 5. <IMAGE>

Title: Monitoring apparatus for monitoring the formation of quires in printing machines
Inventor: BOETTCHER ROLF
IPC: B65H7/12
Filed: 1984-07-03
Abstract: The invention relates to a monitoring apparatus for monitoring the formation of quires in printing machines and emission of an error signal when quires are formed incorrectly owing to the occurrence of double sheets or defective sheets, which apparatus ensures a high degree of display reliability even at higher speeds, with a simple structure. To achieve this, the deviation from the desired value occurring at the control point in the event of a defective sheet or a double sheet must be directly converted into an error signal by a corresponding apparatus. According to the invention, this object is achieved in that a feeling arm, which presses onto the surface of the control point and the position of which can be fixed, has a leaf spring which is fastened on one side and an inductive sensor, the movable transmitting pin of which rests on the rear of the leaf spring and emits a DC voltage which is analogous to the position of the leaf spring and is compared with a reference voltage. The latter is generated from a stabilised DC source by means of a high-accuracy multiturn potentiometer. The type of defect, i.e. a defective sheet or a double sheet, is in each case indicated by means of a light emitting diode. <IMAGE>
