Title: Fuel distribution rail for a mixture-compressing, multicylinder internal combustion engine
Inventor: LEMBERGER HEINZ
IPC: F02M37/42
Filed: 1986-09-24
Abstract: A fuel filter is arranged on a fuel distribution rail for the injection nozzles of a mixture-compressing internal combustion engine. In internal combustion engines fitted in motor vehicles, the fuel filter is firstly thereby located outside the range of dirt and splash water and secondly the distance travelled by the fuel between the fuel filter and the injection nozzles is thereby kept short so that the risk of fuel contamination is considerably reduced. Furthermore, various possibilities for replacement of the fuel filter are proposed (filter cartridge or filter insert).

Title: Process and device for introduction of gas into, and flotation of, free-flowing biomass suspensions
Inventor: SCHMITZ DIETER DR ING
IPC: C02F3/02
Filed: 1987-02-06
Abstract: The invention relates to a process and a device for introduction of gas into, and flotation of, free-flowing biomass suspensions in shaft-like vertical reactors. It is particularly suitable for treating waste water (effluent) by the activated sludge principle. The air required is introduced radially into the descending volume stream of the downflow leg by a self-inducing aeration apparatus, shear forces are produced, the air bubbles are forced into the water and dissolved at an accelerated rate. By means of a shaft head expansion, the oxygen content from the deep water supersaturated with oxygen is maximally utilised for the metabolic processes of the biomass situated in the shaft head. The device developed comprises a tower- or shaft-like vertical reactor, a gas-introduction apparatus, a degassing vessel and a circulation pump. The gas-introduction apparatus comprises an annular nozzle and a gas feed tube. Beneath the annular nozzle is connected a turbulence and dispersion space which opens out directly into the downflow leg. The ascending biomass suspension passes from the shaft head, via a degassing vessel, to the circulation pump, the pressure side of which is connected to the annular nozzle. High gas input levels are achieved with low energy consumption and in the vertical reactor, high biomass concentrations are achieved with increased metabolic activity. <IMAGE>

Title: Electrical plug connection, especially for heating systems
Inventor: DIRZUS ERICH DIPL ING DR
IPC: H01R13/66
Filed: 1987-06-05
Abstract: A plug connection is proposed for connecting an electrical load to a controller, especially for the use of heating systems, it being possible to connect a first plug connecting part (10) on the load side to a second plug connecting part (21) on the controller side. The first plug connecting part (10) on the load side has a relay (18) which switches the operating current for the load (40) on and off and is controlled from the second plug connecting part (21). In consequence, the controller can be provided with a large number of control outputs, each of which manages without a costly relay, which occupies a large volume. The relay which is required for switching the load current is accommodated in that plug connecting part (10) which is connected to the load, so that the number of relays used always corresponds to the number of connected loads. At the same time, the controller can be designed to be small, cost-effective, and capable of versatile use. <IMAGE>

Patent DE-3743580-A1 (DE)
Inventor: SCHEEK BERNHARD
IPC: B29C55/08
Filed: 1987-12-22
Abstract: The object of the invention is to allow cooling emanating from the hollow space of the bent roller to be transferred evenly onto the outside of the expander roller. For this purpose, the hollow spaces inherent in the design are filled by a conductive material, preferably aluminium, in the form of a moulded part adapted exactly to the shape of the respective hollow space. This configuration achieves not only a more uniform cooling on the outside but also an approximately even film of condensate between the expander roller and the material to be dried. This film of condensate serves as a parting line between the expander roller and the material to be dried. <IMAGE>

Title: Speech recognition method and device
Inventor: ARIYOSHI TAKASHI
IPC: G10L15/32
Filed: 1988-06-06
Abstract: In a speech recognition method, an unknown input speech sample of an unknown input speech is firstly generated from features which have been extracted from the unknown input sample. Then a degree of similarity is calculated between the generated unknown sample and reference samples which are composed of reference samples which have been used exclusively for a speaker-independent recognition and composed of reference samples which have been used exclusively for a speaker-dependent recognition. Subsequently, the degree of similarity of each candidate is corrected either with respect to the speaker-independent or with respect to the speaker-dependent recognition, in that the degree of similarity is subjected to a predetermined operation; subsequently a candidate having the highest degree of similarity is determined on the basis of an identification result. In the speech recognition device, the corresponding devices are provided for carrying out the speech recognition method according to the invention, the speech recognition device having a coefficient storage device in order to correct the degree of similarity obtained correspondingly, as well as a speech identification device, in order to compare the degree of similarity of the candidate which has been supplied either during a speaker-independent recognition or during a speaker-dependent recognition with corrected degrees of similarity of the candidate who...
