Title: Method and circuit arrangement for transmitting information signals between control devices which are connected to one another via a highway system which is operated as a function of direction
Inventor: BITZINGER RUDOLF DIPL ING
IPC: H04L12/433
Filed: 1981-09-15
Abstract: The invention relates to a method and a circuit arrangement for transmitting information signals between control devices which are connected to one another via a highway system which is operated as a function of direction. In order to transmit information signals in a protected manner between any two control devices (ST1 to STn) in the highway system (CB) which is operated as a function of direction, the invention provides for the information signals to be transmitted in the form of information signal blocks. Such an information signal block contains a receiving address of the receiving control device, data signals, a transmitting address which designates the transmitting control device, and a control information signal. This control information signal is possibly modified in the receiving control device (STn) and is sent back in the form of an acknowledgement information block to the transmitting control device (ST1). In the transmitting control device (ST1), a received, modified control information signal is interpreted as a reception acknowledgement and a non-modified control information signal is interpreted as a reception block of the previously addressed receiving control device (STn). <IMAGE>

Title: Gearbox casing for the drive of a vertical rolling stand
Inventor: MARES VACLAV
IPC: B21B35/12
Filed: 1981-09-30
Abstract: The invention relates to a vertical gearbox casing for the drive of work rolls of a vertical rolling stand for billet mills, in which the vertical electric motor is accommodated in parallel with the pinions. The invention provides a vertical gearbox casing which is mounted on the vertical stand. The arrangement of this gearbox casing makes it possible to accommodate the vertical electric motor in close proximity to the vertical stand and to simplify it. The requirement that exchange of the spare cartridges of the work rolls of the rolling stand from both sides of the stand be possible is simultaneously fulfilled. The mass of and work expended on the entire drive of the rolling stand are thereby reduced. The invention consists essentially in the provision of a gear mechanism which is formed by two spaces, of which the upper space is used for mounting the spur gear mechanisms and a lower space is used for mounting the gear mechanisms of the pinions which are mounted on the driving shafts. The driving pinion is connected to the output shaft of the spur gear mechanisms, the said output shaft passing through the wall between the upper and the lower space of the gear mechanism, and the outlet driving shafts, which are connected to the pinions, emerge from the lower space of the gear mechanism.

Title: Method and device for the operation of a gas turbine
Inventor: HUETHER WERNER DR ING
IPC: F02C3/26
Filed: 1981-11-10
Abstract: In the case of a coal dust fired gas turbine plant with direct hot gas ignition an inertial filter (6) is arranged between the combustion chamber (5) and the first turbine stage (7), in which filter a curved flow, for example a circular flow, is induced, which filters out the heavy hot gas ash particles on the inertial and/or centrifugal force principle. The first turbine stage thereby admits only purified hot gas which no longer contains any larger ash particles which might attack erosively the rotor and guide blades of the turbine. The inertial filter (6) is preferably composed of highly compacted, heat-resistant ceramic and creates a filter action without significant throttle effect and without the insertion of a physical filter element, giving a gas turbine (7, 8) good efficiency with improved service life. <IMAGE>

Patent DE-3202611-A1 (DE)
Title: Substitution of variable memories for a large proportion of the control logic of a processor
Inventor: EITRICH FRANK-THOMAS
IPC: G06F9/26
Filed: 1982-01-27
Abstract: The internal sequence of all functions of the processor described is controlled by a variable microprogram. An optional complexity is achieved by designing the microprogram as a basis for the possibly also programmable selection of subunits which directly switch their associated functions (registers, ALU ...). This makes it possible to select very many functions in arbitrary sequence in spite of the relatively small number of bits per word of the microprogram which suggests a universal design for the processor architecture (large number of registers, possibly several ALUs, special functions, bits per data word as required ...). The patent deals with supporting these alternatives by means of an extremely variable control of the microprogram sequence in that it provides the capability for conditional branches, multiply interleaved loops and subroutines and changes in the microprogram by itself and thus achieves a complexity at the microprogram level which was previously reserved for the programming languages. An obvious application is the construction of a universal computer which, with appropriate microprogramming, could process existing programs of other processors unchanged or would even be capable of directly processing an interpretive high-level programming language.

Patent DE-3204837-A1 (DE)
Title: Lighting system for the passenger compartments of motor vehicles
IPC: B60Q3/02
Filed: 1982-02-11
Abstract: In a lightening system for the passenger compartments of motor vehicles having at least one lamp, at least one operating switch, particularly in the form of a door contact, which switches the lamp on and off, having a timer circuit coupled to the operating switch, and having a switch which is controlled by the timer circuit, arranged in the feed circuit of the lamps and, after the operating switch opens, keeps the feed circuit closed for the duration of a delay time determined by the timer circuit, a pulse generator which responds to a change in the operating state of the operating switch is coupled to said switch and the timer circuit contains an activation switch which is controlled by the pulse generator and has a latching device, said switch connecting the timer circuit to the feed voltage until the delay time runs out, upon reception of a control pulse supplied by the pulse generator. By means of this design of the lighting system, it is ensured that the timer circuit can only be activated by a change in the operating state of the operating switch and remains activated at most until the delay time runs out so that the timer circuit only receives current during this delay time and, if appropriate, when the lamp is still switched on.

Title: Process for improving the heat balance in converters and other metallurgical vessels in steel manufacture
Inventor: LIPPE WOLFGANG DIPL ING
IPC: C21C5/28
Filed: 1982-09-20
Abstract: In the basic steel manufacturing processes, it is well known from the refining process that silicon burns off before the carbon. The silicon combustion has not been widely investigated as stated in the literature - not at all in the opinion of the author. It is known that the heat of reaction resulting from the combustion of silicon is greater than that from the combustion of carbon. It is also known that the heats of mixing from the formation of silicates of lower metal oxides are considerably greater than the heat of reaction in the combustion of silicon and carbon. Since, however, as already stated, nothing or too little is known about the mechanism of the silicon combustion, it is also impossible to work consciously with the heat of mixing resulting from the formation of silicates of lower metal oxides. With the combustion of silicon subsiding, the silicon content of the melt decreases more and more, and the formation of silicates of lower metal oxides increases more and more. It is therefore proposed to start with a smaller silicon content and, after this has been burned off, to pass several times through the range of the most extensive formation of silicates of lower metal oxides, with their enormous heat of mixing, by one or more further additions of very small silicon contents or by blowing in very small quantities of silicon. The deliberate utilisation of the heat of mixing makes it possible to manage overall with smaller silicon contents and consequently also with smaller quantities of arising silicate, so that the lining is attacked less and correspondingly the addition of lime is smaller...
