Patent DE-4227680-A1 (DE)
Title: FM receiver with RDS evaluator - has control determining difference between two frequencies, and matching times for various frequency differences
Inventor: DORNBUSCH HELMUT
IPC: H04H20/26
Filed: 1992-08-21
Abstract: On reception of an RD programme on a first frequency, the control (7) switches timewise to at least one second alternative frequency of the programme for the reception quality testing. During this testing, the receiver reproduction is mute. The control determines the difference between the two frequencies. Different turning times are preset to the control for various frequency differences. The times are needed by the receiver until it is tuned to a new frequency in dependence on the frequency difference. At the time point of determining the reception quality alternative frequency, the control selects the mute switching time in dependence on the preset tuning times. ADVANTAGE - Reduced number and length of interruptions.

Patent DE-4303656-A1 (DE)
Title: Household steam cooker
Inventor: KLUETER GERHARD
IPC: A47J27/16
Filed: 1993-02-09
Abstract: The invention relates to a steam cooker which has a separate steam generator outside the cooking space and can be used in the household.   The present invention is confronted with the problem of developing a steam cooker which also works with excess pressure and is safer owing to the fact that a free fall distance of 100 mm exists between fresh and used water without steam having to be emitted out into the environment. The solution to the problem ensues from the fact that the free fall distance is realised in the region of the fresh-water supply. The fresh water passes via a valve (1) into a water container (2), continues via a pressure-elevating pump (3) to a three-way valve (6) and is conveyed here into the different fresh-water supply regions. In the container (2), a level electrode (5) regulates the water level and present in its side walls, above this water level, are openings (4) which exist to prevent used water from being sucked back into the fresh-water line (7). <IMAGE>

Patent DE-4311441-A1 (DE)
Inventor: DREYER ROBERT S
IPC: G06F9/38
Filed: 1993-04-07
Abstract: A microprocessor is disclosed herein with an idle mode of operation. The microprocessor provides a very quick interrupt that can be asserted externally. A Run/Stop (R/S) pin on the chip is asserted to access and hold the idle mode. The R/S pin is electrically connected to a central control unit. An additional pin, which may be termed an "acknowledge pin", is provided to indicate when the microprocessor is in the idle state. The R/S pin and the acknowledge pin can be useful for any operation in which the microprocessor must be stopped quickly, and can be used for bus control, debugging, diagnostics, multi-processor synchronization, and direct memory access operations. The idle mode is asserted between instructions, at an instruction boundary following execution of one instruction, but before execution of the next, when the execution unit has completed all its modifications of registers, flags, and memory for a first instruction, but before it begins this modification for the next instruction following in the pipeline. In the idle mode, the decoder does not issue instructions into the pipeline, but the clock operates normally and other microprocessor functions are operable. A port may be provided, with a secondary control unit for issuing simple instructions directly to the execution unit, bypassing the normal instruction issue process. The present invention can be useful for implementing debugging and remote diagnostic systems, and also for synchronizing microprocessors running in parallel.

Patent DE-4324969-A1 (DE)
Title: Method for crack detection in ferromagnetic materials
Inventor: BOENISCH ANDREAS
IPC: G01N27/90
Filed: 1993-07-24
Abstract: A method is described which makes it possible, during surface-crack testing of ferromagnetic material using eddy currents, to differentiate between cracks and other surface defects which do not impair quality and usability. If an alternating field is applied to the coil sensors in the frequency range of 10 kHz to 1 MHz, then inductive feedback causes the formation of eddy currents in the test object. When the feedback is represented in the impedance plane, a different phase relationship results for crack indications compared to indications which are caused by notches, tears and the like. Unambiguous crack detection is thereby possible.
Patent DE-4325086-A1 (DE)
Title: Nozzle arrangement for compressed-air blasting
Inventor: FROHNE KLAUS
IPC: B05B7/14
Filed: 1993-07-21
Abstract: The invention relates to an arrangement of nozzles for generating a working blast during compressed-air blasting. The purpose of the invention is to increase the efficiency by maximum utilisation of the compressed-air energy. The object consists in achieving a high charging of the compressed-air stream with blasting medium without exceeding the passing-through capacity of the nozzle generating the working blast. As a solution, there is proposed an arrangement having two nozzles of different diameter which enclose an axial interspace. The latter is connected to the region in front of the entrance of the smaller-diameter nozzle arranged first in the blasting direction. As a result, the compressed-air/blasting-medium stream is divided into two part-streams, one of which passes through the first nozzle and is accelerated therein, while the second part-stream goes round this nozzle and it is only downstream of its mouth that it is combined with the first part-stream on entering the second nozzle. The charging of the entire stream with blasting medium can thus be increased without the first nozzle, which generates the propulsive jet, being blocked. <IMAGE>

Title: Simple device for the rapid synthesis of a bar code symbol
Inventor: OBERNIK HARTWIN
IPC: G06K1/12
Filed: 1993-08-04
Abstract: Instead of bar code symbols which are produced by complicated devices, according to the object direct manual construction of a complete symbol and rapid interchange of the content of the useful characters in the symbol are now intended to be made possible. The solution is an encoding slide 1 which contains, in a block-shaped housing 2, a number of rigid rod tongues 3a...3k which are held between the edges 4 and 5 of the frame and can be displaced with respect to one another. On flat surface sides 9 and 10, these tongues carry a complete character set 22, 24...30; 33, 35...41 of the selected 2/5 matrix code script. Bars and gaps in the characters, which are of equal area, are aligned parallel to the bevels 7 and 8 of the tongues. A display window 6 located in the central field of the housing exposes a view of the multiposition bar code symbol constructed, including clear text characters. By sliding the tongues, the symbol can be rapidly changed. The bar code slide (Fig. 1) finds application wherever article-specific information for the user are missing, are to be arranged or are to be produced in a hurry, such as for example in the management of storage, in the household or during training. <IMAGE>
