Title: Redundant memory access circuit for dynamic random access memory - responds to defective main memory cell address to select redundant memory cell and isolate corresponding data bus
Inventor: CHUNG JIN-YOUNG
IPC: G11C8/00
Filed: 1992-09-30
Abstract: The access circuit allows data extraction from a redundant memory cell array instead of from a defective memory cell of the main memory cell array, using an address decoder with a pre-decoder and a main decoder. The address decoder is coupled to the main memory cell array via a column selector/column sampling amplifier and a bit line sampling amplifier, with a column protection/redundancy column selection circuit coupled to the pre-decoder, generating a redundant memory selection signal and a data bus isolation signal in dependence on the location of the defective memory cell. The column selector/column sampling amplifier and the redundant column selector/column sampling amplifier are each coupled to a respective data bus, with data bus isolation or selection dependant on the defective memory cell address. ADVANTAGE - Simultaneous switching to redundant data and data bus isolation.

Inventor: BAEHR GOTTFRIED
IPC: F24S50/20
Filed: 1993-02-20
Abstract: Today's atomic power supply plants involve considerable costs and problems in respect of the installation, repair, maintenance and waste-disposal work. According to the invention, concerning the technology of energy conversion, in particular photovoltaics, according to P 4235290.8 a mount is disclosed here which makes it possible to assemble and disassemble in a very short time the installation of entire colonies of radiation-tracking energy conversion plants, such as photovoltaic plants, in particular also to carry out a reparative replacement which becomes necessary. This can be done with and without rapid cabling from one plant to another. The system is, in the case of installation on meadows by means of a raised pedestal, also transportable during the mowing work and thus is totally environmentally friendly. It can be moved and installed without problems since, without adjusting the system, it carries out the tracking of the radiation by means of its sensor installed in each plant via the vehicle electrical system.

Title: Device for cleaning articles
Inventor: SCHREIBER WALTER DIPL ING
IPC: B08B13/00
Filed: 1993-03-30
Abstract: A device for cleaning articles has a cab (11) with a front wall (13) which is designed as a pivoting flap and in which a window (22) and two gripping openings (19) are arranged. Below the cab (11) there is a container (38) for cleaning liquid, for example a cold cleaner. The liquid is conveyed at high pressure via a liquid pump (46) to a jet lance which can be handled inside the cabin so that even narrow gaps in the article can be cleaned using the jet of liquid. The liquid passes back into the container (38) via a screen insert (35) of a collecting channel (34, 44). The air in the cab is recirculated by means of a blower (27) and, during this process, the moisture distributed in the air is precipitated. This counteracts misting inside the cab in order, on the one hand, to maintain free vision and, on the other hand, to prevent the occurrence of explosive mist/air mixtures. Instead of the liquid, compressed air can also be fed to the jet lance in order to dry the article to be cleaned. <IMAGE>

Title: Method for determining a switching sequence and switching sequence for a plurality of switchable reference elements
Inventor: DRAXELMAYER DIETER DIPL ING DR
IPC: H03M1/66
Filed: 1993-05-07
Abstract: In arrangements having a plurality of identical switchable reference elements, in particular in A/D and D/A converters, the matching of the elements is critical to the quality of the desired result. To compensating for errors (faults) of the reference elements, a method for determining the switching sequence and a switching sequence are proposed, in which the error of each reference element is represented by an error polynomial which is terminated after a number of terms, where each term of the polynomial is characterised by a predetermined function, with the aid of which the error component, assigned to the term, relating to the reference elements is calculated in such a way that the integral of the function is minimal, and in which, starting from a reference element, further reference elements are selected step by step in such a way that the cumulative (summated) error component remains within a predetermined error limit. An applicable secondary condition is that each reference element is used only once.

Title: Steaming equipment between spinning and winding - has mechanism to hold the cops for a drying off period
Inventor: HASUI KEINI
IPC: D02J13/00
Filed: 1993-06-09
Abstract: Between a spinning frame and automatic winders is a transport system for the cops. These pass through a steaming process. Additionally, equipment is installed to ensure the cops do not retain condensn.. Pref. the conveyor band (L1) from the spinning frame (1) supports the cops on a round plate with central stud, which may have identification details, for selection purposes. Control gates (7,8) are fitted to each end of the steaming arrangement (5), so that storage space (L4) is left, to regulate the vol. of cops, and to create a delay to enable to cops to dry off. In this region, it may also be arranged for equipment to tbe installed to dry off the cops, by hot air, in which case the transport line (L4) may be conc. in a chamber. When the cops have passed through the gate (8), they enter the yarn loose end release mechanism (4). The selected cops then proceed to the respective winder (3) and empty tubes are released to the band (L7) for return to the spinning frame. USE - The steaming process is employed to relax the natural fibres of the yarn following spinning. This prevents snarling at the winder, and other reasons for the treatment.

Title: Mfg. starter crown gearwheel for motor vehicle engine - Cold deforming sheet metal blank to exhibit outer gear tooth of real running wheel geometry
Inventor: DERAIZ DANIEL
IPC: F16H55/17
Filed: 1993-06-30
Abstract: A wheel flange extends to a workpiece axis (Z) in integral joining with a surface extending in cylindrical fashion in parallel and coaxial with the axis (2). This surface is cold deformed by the crude method to exhibit an outer gear tooth (13) extending from the real running wheel geometry. The wall strength of the surface is changed by cold deformation. The distance (16) of the root line (14) to the nearest point of the inner surface (15) of the finished outer surface (12) is smaller than the wall strength of the latter so that the root line of the outer gear tooth runs always within the finished surface (12) to which the gear wheel belongs. The rotation of the workpiece with thee roller heads used in the prodn. process can be synchronised by mechanical and/or electronic equipment. ADVANTAGE - Avoids prodn. of wall strength that is too weak for initiating starting of i.c. engine by electromotor energised by car battery.

Title: Control device for a motor vehicle automatic transmission
Inventor: NEUNER JOSEF
IPC: F16H61/02
Filed: 1993-07-06
Abstract: An electro-hydraulic control device for a motor vehicle automatic transmission is proposed, which is designed so that it functions reliably in all operating stages. This is achieved in that the operating stages D, R and N are selected by pressure actuation of individual gearshift elements (2, 3, 12), whilst the operating stage P is selected by depressurising all gearshift elements (2, 3, 12). It is furthermore proposed that in changing over between the operating stages D, R and N two solenoid valves (7, 8, 9) be switched in each case. In addition, the selector device (15) is coupled to the parking position (1) by a second control device so that engagement of the parking position (1) is prevented when the operating stage P is not selected on the selector device (15). <IMAGE>

Title: Compressed-air system for utility vehicles
Inventor: STUERNER JOHANN
IPC: F01M11/08
Filed: 1993-07-27
Abstract: A compressed-air system for utility vehicles with an internal combustion engine (38) contains an oil-lubricated compressor (10) which is connected via a line system (12) to a number of devices (16, 18, 20) arranged downstream. Located between the devices and the compressor is an oil separator (14), the oil-collecting space (24) of which is connected to the crankcase of the engine via lines (28, 32) and a valve (30). The valve (30) is opened briefly in each case at predetermined time intervals or at predetermined times, but is otherwise closed. In this way, the pressure of the compressed-air system is prevented from being reduced in the direction of the crankcase and an excessively high pressure is prevented from arising here. Brief opening phases of the valve (30) are sufficient to deliver the collected oil and condensate mixture with a pressure surge in the direction of the crankcase. <IMAGE>

Patent DE-4343090-A1 (DE)
Inventor: DANIEL WALTER DIPL ING
IPC: F23C6/00
Filed: 1993-12-17
Abstract: A method is for the staged combustion of a fuel/combustion air mixture, in which sub-stoichiometric combustion takes place in a first slow combustion section and the CO content in the combustion gas is reduced to an admissible value by the supply of oxygen in a second slow combustion section. It is proposed that the fuel/combustion air mixture be divided between two partial burners (10, 12) or (50, 52) Fig 2 and the mixing ratio in the partial quantities be set so that rich combustion takes place in one partial burner (10 or 50) and lean combustion takes place in the other partial burner (12 or 52). Then, the combustion gases are routed into a downstream reaction chamber (36 or 76), in which the CO in the one combustion gas is reacted with the O2 in the other combustion gas. In this way, the fuel and combustion air can be mixed without difficulty upstream of the combustion zone of the blower burner. <IMAGE>
