Title: Method for the transmission of television signals which can be used only by a limited user group
Inventor: CHRISTOPH MARTIN
IPC: H04N7/169
Filed: 1984-10-11
Abstract: Synchronising pulses are coded, for example by reduction, in the emitted television signals. In the case of the users who belong to the limited user group, for example subscribers, the synchronising pulses are regenerated in a decoding device. For this purpose, marking pulses are transmitted to the decoding devices at the same time as the television signals, for example by being modulated onto a control carrier. The marking pulses are transmitted, for example, once per frame and at most partially coincide with the coded synchronising pulses in time. Switching pulses, which are used for regenerating, for example boosting, the synchronising pulses in the television signal and have positions which are or can be predetermined in time with respect to the marking pulses which are supplied from a control-carrier receiver (19) are produced in a pulse-conditioning circuit (21) in the decoding device. Theft of the signal is made more difficult by means of the pulse-conditioning circuit (21) which is required. <IMAGE>

Title: Saw blade
Inventor: TSUNE RYOICHI
IPC: B23D61/12
Filed: 1984-10-22
Abstract: The invention relates to a saw blade for a bandsaw or a circular saw, in which a saw-blade body (11) is of thin design and straight teeth (16) directly below the thin-shaped saw-blade body are designed so as to be concentric to and integrated with the body. At the same time, the tooth-base side is formed in the thin-walled section of a thickness which is equal to or almost equal to that of the saw-blade body, while the cutting-edge side is formed in the thick-walled section. Accordingly, a path for the disposal of the chips is formed between the workpiece and the saw-blade body on account of the difference between the thickness of the thick-walled section (15) of the straight teeth and the saw-blade body (11). <IMAGE>

In consequence, even relatively small orders can be processed economically. <IMAGE>
Patent DE-3442130-A1 (DE)
Title: Process for surface-hardening into the bainite zone of castings of ductile iron-carbon casting materials
IPC: C21D1/20
Filed: 1984-11-17
Abstract: Castings with a bainitic-austenitic structure have a higher strength and fatigue strength and better wear resistance than the ferritic to perlitic grades. In order to avoid the poorer machining properties and the delay of a bainite hardening throughout, surface-hardening of only the particularly stressed regions into the bainite stage has already been carried out, namely by inductive heating and quenching in hot oil or in salt baths. The expensive hot baths are avoided according to the invention by preheating the castings as a whole to a temperature approximately corresponding to the intended transformation temperature and rapidly heating the surface zones or casting regions to be hardened to a temperature from 880 DEG  to 950 DEG C. From these, the heat rapidly flows off into the only moderately preheated interior of the casting, so that the austenitised regions have to be cooled only slightly by moving air or spray mists down to the vicinity of the intended transformation temperature. Immediately afterwards, they are transferred into a furnace preheated to the transformation temperature. Because of the short delay, machining can be carried out before the surface-hardening.

Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-02-14
Abstract: It is known to separate out SO2 and NOx simultaneously in scrubbing apparatuses. For this purpose, alkalis and hydrated lime or limestone are added to the scrubbing liquid and EDTA is additionally added. In order to have to use the lowest possible chemical addition to maintain the iron chelate such as EDTA and a chemical addition to maintain the reducing phase, according to the invention it is proposed that, preferably in the case of flue gases having a relatively high NOx content and relatively low SO2 content, the gas (1) is first introduced into a scrubbing stage (2) and here, for simultaneous scrubbing of SO2 and NOx, is impinged with a reducing scrubbing liquid at (7), which transfers the discharging scrubbing liquid stream via a descending pipe (11) to the scrubbing liquid reservoir (6), and a scrubbing liquid stage (3) is situated downstream of the scrubbing liquid stage (2), which scrubbing liquid stage (3) preferably serves for scrubbing out SO2 and this scrubbing stage is provided with a scrubbing liquid reservoir vessel (5) which maintains the scrubbing water circulation with oxidising scrubbing liquid, via a pump, in the region (3) for SO2 scrubbing and the gas, which is partly freed from NOx and largely freed from SO2, is passed via a gas pipe (10) having a demister shielding to the scrubbing stage (4), in this scrubbing stage, according to the invention, a scrubbing liquid having reducing properties being produced, which [lacuna] the NOx scrubbing with the addition of limestone ...

Title: Process for generating defined dispersed systems, and arrangement for carrying it out
Inventor: MIETH HANS-OTTO
IPC: B01F15/04
Filed: 1985-04-25
Abstract: The invention makes it possible to control directly the admixture of the dispersed phase to the continuous phase via the concentration of the dispersed fractions. These advantages are achieved by   a degree of turbidity of the continuous phase being measured by means of a turbidimetric method before and after an admixture of the dispersed phase, the difference of the degrees of turbidity being used to determine a concentration of the dispersed phase in the continuous phase and by controlling, as a function of a setpoint/actual value comparison of the concentration, the admixture for the dispersed phase.   The use of the process according to the invention and an arrangement for carrying it out make it possible, for example, to produce a defined suspension from brewer's yeast and wort by proportioning the brewer's yeast according to the cell count (Figure 3). <IMAGE>
Patent DE-3515106-A1 (DE)
Title: Magnetic key arrangement
Inventor: FLIEGE HANS DIPL ING
IPC: G07C9/00
Filed: 1985-04-26
Abstract: The magnetic key arrangement comprises a large number of magnetic field sensors (11, 13) which preferably read key-code data of a magnetic key (1) in parallel. A control circuit (31) stores in a memory (41) for each of the magnetic field sensors (11, 13) the amplitude value of its signal which is produced when the magnetic key (1) is not inserted. The control circuit (31) updates the stored amplitude values if the instantaneous amplitude value when the magnetic key (1) is not inserted deviates from the stored amplitude value. The signals which are produced by the magnetic field sensors (11, 13) during reading of the magnetic key (1) are converted into binary key-code data as a function of threshold values related to the stored amplitude values, and are compared with binary key-code data which are predetermined in the control circuit (31). In order to reduce the number of connecting lines between the magnetic field sensors (11, 13) and the control circuit (31), the control circuit (31) is connected to the magnetic field sensors (11, 13) via a multiplexer (19). In order to reduce the power consumption, the operating voltage of the magnetic field sensors (11, 13) and of the multiplexer (19) is pulsed. <IMAGE>

Title: Method for direct firing of a tunnel furnace as well as tunnel furnace for implementing the method
Inventor: PULS OTTO
IPC: F27B9/30
Filed: 1985-05-17
Abstract: In the direct firing of a tunnel furnace for baking ceramic products, in particular containing combustible or gasifiable substances, harmful substances are to be prevented from being discharged into the atmosphere with the waste gases. This can be achieved in that the gas flow is circulated in the preheating zone of the tunnel furnace in order to expel at as early a stage as possible the porosifying agents contained in the articles to be baked. Since, as a result, the entire gas flow can be kept small in the preheating zone, a waste gas flow which is concentrated in harmful substances arises, which is guided back into the crash-cooling zone.
