Title: Fluidised-bed reactor for producing activated carbon
Inventor: HESCHEL WOLFGANG DR ING
IPC: C01B31/08
Filed: 1988-07-22
Abstract: The invention relates to a fluidised-bed reactor for producing activated carbon, in particular powdered carbon of high adsorption capacity, from recent or fossil carbon carriers, for example from wood chips fresh from the forest or from lignite. Starting from a fluidised-bed reactor having an approximately vertical pipe for feeding the material, the pipe is designed in the form of a shaft reactor and, for this purpose, at least one gas feed or/and gas discharge are connected to the pipe. In this shaft reactor/fluidised-bed reactor combination, it is possible to narrow the wide residence time spectrum typical of single-stage fluidised-bed reactors. <IMAGE>

Title: Process for the preparation of transparent mixtures of aromatic polycarbonates and poly-C1-C8-alkyl (meth)acrylates
Inventor: MEIER ERICH DIPL ING DR
IPC: C08J3/00
Filed: 1988-09-30
Abstract: Transparent mixtures of aromatic polycarbonates and poly-C1-C8-alkyl (meth)acrylates are prepared by melting the polymers employed in the presence of supercritical gases or gas mixtures, intensively mixing the molten polymers until the viscosity of the melt has dropped by at least 10%, cooling the polymer melt with further mixing until the viscosity of the melt has re-attained at least the value of the original viscosity, then cooling the melt by at least a further 30@C and subsequently decompressing the mixture. The transparent mixtures prepared in this way can be converted in a conventional manner into mouldings for optical and mechanical applications.

Patent DE-3912741-A1 (DE)
Inventor: LUECK BERNHARD DR
IPC: B01D61/00
Filed: 1989-04-19
Abstract: The invention relates to a diagonal flow filter module, particularly for ultra- and microfiltration. The diagonal flow filter module consists of a cuboid stack element (5) with alternating flow channels (9) for crude solution or retentate and filtrate channels (10), which are separated from one another in each case by a filter membrane (6). The flow channels (9) are closed off at the side walls of the stack element (5), while the filtrate channels (10) have openings at the side walls for the discharge of the filtrate. The flow channels (9) are open at the end faces of the stack element (5) and the filtrate channels (10) are closed. The ends of the stack element (5) are sealed to a housing (1) with a synthetic resin composition. Sealed to the end faces there are end caps (12) with the connections for crude solutions and retentate which, together with the seal between the stack ends and the housing (1), ensures a reliable separation between retentate and filtrate space. The filtrate leaves the stack element (5) at the side walls, is collected in the housing (1) and withdrawn through one or two drainage connecting pieces. The diagonal flow filter module has an improved flow guidance system and permits a larger connection cross section to be realized.

Title: Accurate milling of cam profile - involves third axis feed movement to compensate for parallelism error
Inventor: BLAESCHE ECKEHARD
IPC: B23Q1/00
Filed: 1989-04-22
Abstract: The cam profile is often produced by milling with a bevelled face mill (6) having the axis (7) inclined by the amount of the bevel angle.  Two-controlled feed motions, one rotational about the cam axis (4) and the other normal to the cam axis in the direction (11) are applied to produce the cam profile.  It can be shown that the cam surface deviates from parallelism with the cam axis (4). Greater accuracy can be achieved by providing a further controlled feed axis in the direction normal to the plane of the cam axis (4) and the cutter axis (7). USE/ADVANTAGE - Mfr. of LC engine and other machinery.  Cams with a wider face can be accurately produced.

Title: Agricultural tractor coupling - is controlled by valve, hydraulic pump and electronic evaluator with coupling speed sensors
Inventor: JENRICH REINHARD DIPL ING
IPC: A01B61/02
Filed: 1990-01-19
Abstract: The coupling lies between the drive train of a motor and a short branch shaft (1). The coupling is engaged and disengaged via a control valve (4) and a hydraulic pump (3).

Inventor: FRONIEWSKI JOZEF
IPC: G06F5/16
Filed: 1990-06-13
Abstract: In a FIFO (or LIFO) buffer memory, reading and outputting of stored data elements are pipelined by look-ahead reading in the read cycle corresponding to a present request a memory cell containing the data element to be next requested. But the data so read in advance is not outputted until the read cycle corresponding to that subsequent request. The first data element written into the serial memory is stored in an initial data register 12. Upon the first read request, that first data element is outputted from the initial data register. A first and a second memory array 4, 6 are provided for alternatingly storing successive ones of data elements written into the buffer memory. While a presently requested data element from the first array is being outputted, a memory cell in the second array, which contains the next data element to be requested, is selected and sensed, and that sensed value is placed on an output line. Upon receipt of the next request, the value maintained on that output line is outputted, and a memory cell in the first array, which contains the next data element to be requested, is selected and sensed, and that sensed value is placed on an output line. And so on. <IMAGE>

IPC: B60T8/88
Filed: 1990-09-12
Abstract: Proposed is a control circuit for a large number of consumers (5), e.g. the electromagnetically operated multi-way valves in a vehicle-brake anti-blocking system (MWV1-MWVn). The circuit comprises a control unit (2, 3) whose output signals are fed via amplifier stages (4) to the consumers (5). The individual amplifier stages (4; VS1-VSn) are designed as so-called "intelligent power drivers" and consist substantially of a power amplifier (18) with integrated control and monitoring electronics. The control unit (2, 3) and the amplifier stages (4; VS1-VSn) are linked together to form a closed loop or chain. Data is transferred from a synchronous, serial interface in the control unit (2, 3) to the individual amplifier stages (4; VS1-VSn) and back to a serial input in the control unit (2, 3). In one embodiment, a position in a data word is allocated to each amplifier stage (4; VS1-VSn).
