Title: Four-stroke combustion engine with toroidal and rotary pistons
Inventor: TAEUBER JOSEF DR
IPC: F01C1/063
Filed: 1993-01-13
Abstract: The toroidal piston (6) rotates within the main (Wankel-type) piston (11) and is sealed with rings (20) and secured by spokes to the output shaft (15). The induction stroke begins when a moulding (19) on the rotary piston reaches the cylinder space above a compression piston (17). Compression proceeds as the latter is driven towards its BDC.A spark is ignited (18) and a small fraction of molecular kinetic energy brings the rotary piston to rest while the remainder is imparted to the toroid, shaft and flywheel, and the air cushion (E) shrinks. Finally the combustion prods. are expelled through an exhaust port (A).
Patent DE-4307139-A1 (DE)
Title: Serialisation of operating requests in a multiprocessor system
Inventor: FISCHER WOLFGANG DIPL ING
IPC: G06F15/17
Filed: 1993-03-06
Abstract: A method of making processors (PU0 to Pn) of a multiprocessor system (MP) quiescent, or of serialising bus assignments for the individual processors, is described. This serialisation becomes necessary if one or more processors simultaneously want to execute commands which require uninterrupted ownership of the bus for as long as they are being executed, e.g. to prevent damage to the integrity of data. For this purpose, a quiescent-making network (QN), which connects all processors, is used. Processors which execute such atomic commands receive their bus assignment on a priority basis. The processor with the highest rank puts its competitors into conditional branch command loops (BC loops), in which they wait for a specified condition, e.g. "QN not blocked" (QU+). If this condition is fulfilled, e.g. after the end of an atomic command, the processor with the next lower priority receives the bus. Processors which are executing other commands are forced into a no-operation state (NOP), from which they are released after completion of the atomic command of another processor, to resume their interrupted commands.

Title: Method and arrangement for complete combustion of biomaterials, in particular wood chips, to be combusted in a coaldust-fired steam boiler
Inventor: STROEER KURT DIPL ING
IPC: F26B3/32
Filed: 1993-04-16
Abstract: The invention relates to a method and arrangement for complete combustion of biomaterials, in particular wood chips, to be combusted in a coaldust-fired steam boiler. For disposal and energetic use of the uncombusted material, the uncombusted material is to be brought from the wet ash into a circulating process for combustion in the steam boiler. This is achieved by the uncombusted material, from the biomaterial and coaldust combustion, occurring in the wet ash-removal installation of the steam boiler, being hydraulically separated in a manner known per se from the non-combustible material by floating action, the uncombusted material being separated from the water by filtration and fed continuously to the mill, smoke-gas back-suction or burner system of the steam boiler as secondary fuel. For implementation, the wet ash-removal installation of the steam boiler is connected to an uncombusted material/non-combustible material/water separation arrangement and this is integrated into the mill, smoke-gas back-suction or burner system. <IMAGE>

Title: Electrical installation apparatus, in particular a universal surface-mounted box
IPC: H02G3/10
Filed: 1993-05-08
Abstract: The invention relates to an electrical installation apparatus, in particular to a universal surface-mounted box. This apparatus has a cap-like housing which can be connected to a baseplate. In this case, connecting elements are used, which are designed such that it is possible to detach the connection again. The electrical installation apparatus has insertion openings for cables, lines or the like, as well as devices for fitting holding elements for terminals, busbars, apparatuses or the like.

These latching rockers can be moved from their rest position into an active position when the housing is fitted onto the baseplate. In this active position, the housing is connected to the baseplate. It is possible to detach the connection again only by moving the latching rockers into their ineffective rest position by means of an operating tool, such as a screwdriver. In the case of the preferred embodiment of the invention, the latching rocker consists of a base body, which is mounted on the baseplate so that it can pivot, and a retaining hook, which, in its active position, engages in a recess in the housing.

Title: Method and device for frequency-modulated screening
Inventor: JEPPEL UWE
IPC: H04N1/405
Filed: 1993-07-08
Abstract: The invention relates to a method and a device for frequency-modulated screening of pixels to be scanned and/or to be printed, using a threshold matrix. The object to be achieved is that the image data are computed during the scanning, that is to say in real-time and can be immediately transferred to an exposer unit (for example in a recorder section of the scanner). For this purpose, the threshold matrix is provided with variable values for the screening of different pixels. This combines the speed of half-tone screening with the noise immunity of frequency-modulated screening. The method can be implemented by means of a plug-in card, for example in a drum scanner. The preferred field of application is printing technology with electronic screening, for example in desktop publishing systems or especially in the reproduction technology with scanners.

Title: Process for gasifying refuse by partial oxidation, minimising emissions and maximising the thermal efficiency
Inventor: STOCKBURGER DIETER DR ING
IPC: C10J3/57
Filed: 1993-07-24
Abstract: Process for gasifying refuse by partial oxidation, minimising emissions and maximising the thermal efficiency. The process is characterised by a novel reactor concept. The refuse is introduced through a feed tube arranged concentrically in the circular melt bath reactor. Melt is circulated between reaction compartment and feed tube by oxygen-driven air lift pumps and the refuse is thus mixed intensively with the melt. Gaseous constituents leave the feed tube through special orifices at its lower end. Between feed tube and reaction compartment there is maintained a pressure difference which leads to a level difference between the feed tube and reaction compartment. The gaseous constituents are thus forced into the melt in the reaction compartment. By means of a novel arrangement of purification steps known per se, the crude gas is inexpensively purified, in particular wastewater purification being avoided.
Patent DE-4330739-A1 (DE)
Title: Test device for tractive-unit AC monitoring device
Inventor: BAVEYSTOCK JOHN
IPC: G01R35/00
Filed: 1993-09-10
Abstract: The invention relates to a test device for a 50 Hz monitoring device (10) for tractive units. It has to date not been possible to test a 50 Hz monitoring device with 50 Hz test current from the 50 Hz mains, because the 50 Hz monitoring device does not have exactly the same frequency as the 50 Hz mains. This frequency difference gives rise to a non-constant phase relationship with a large influence on the response threshold. By virtue of the invention of the test device, the influence of the alternating phase relationship is cancelled in that a square-wave signal is supplied to the test device (30) from the generator (11) of the 50 Hz monitoring device (10), filtered in this test device, converted into a sine-wave signal, amplified and used as 50 Hz test current. This 50 Hz test current is synchronised in frequency and in phase with the internal current of the 50 Hz monitoring device and has a 0 DEG , 90 DEG , 180 DEG , 270 DEG  or variable phase relationship. By setting (35) the amplitude of the 50 Hz test current, the response threshold of the 50 Hz monitoring device can be tested with various (32) phase relationships. <IMAGE>

Title: Method for conditioning data for describing image blocks, and arrangement therefor
Inventor: HILDENBRAND KLAUS DR ING
IPC: G06T7/238
Filed: 1993-09-30
Abstract: To condition image data, particularly in accordance with the block-matching method, two memories (SRD, SSD) are provided which in each case temporarily store the image data of a reference image block and of a search block. The image data of the memories (SRD, SSD) are logically combined with one another via comparison units (V1, V2, V3, V4) in such a manner that in each case one group of search positions within the search block can be simultaneously analysed in one processing step. Those blocks of the memory (SSD) for the search block which are not currently needed for the block matching can be updated. The implementation according to the invention allows the conditioning of compressed image data with predetermined speed requirements and/or a predetermined, particularly reduced, hardware complexity. <IMAGE>
