Title: Domestic sewage outflow - has sepn. of solid and fluid phases to allow only fluid to pass through collection channel into the sewage disposal system
Inventor: SCHULZ MIMKE
IPC: E03F5/14
Filed: 1992-08-26
Abstract: At a sewage outflow, the fluid and solid phases are generally wholly sepd. from each other before it enters the sewage collection channel. The fluid phase is passed into the sewage channel, while the solid phase is retained and held. Also claimed is a system with the sepn. unit at the connection (4,5) to separate the fluid and solid phases of the sewage. It allows the fluid phase to pass into the collection channel (6) while the solid phase is retained. A domestic sewage processing unit separates the fluid and solid phases. The solid phase is pumped out at intervals by a pump truck, for disposal, or by a mobile pump for recirculation into the channel system under pressure where the components of the solid phase are ground down and/or saturated with fluid. The fluid and solid phases are separated by sedimentation or filtering. The collection channel of the sewage channel system is angled to give a flow, and is at least partially a pressure channel, or sections have a gravity drop and sections have pressure. All the channels are flushed with a cleaning fluid at times. USE/ADVANTAGE - The system is esp. for domestic sewage removal from dwellings in country area. The action allows sewage pipes to be used which allow fluid to pass through without blockage with small dia. piping.

Title: Vehicle fault signalling for time-dependent redn. of engine power
Inventor: BERGER JOACHIM DIPL ING
IPC: B60K28/14
Filed: 1993-02-03
Abstract: The power of the engine (100) is regulated by a rod or magnetic valve (110) operated by a control unit (120) which selects (135) the lesser of two quantities (Q,QMAX) of fuel to be injected. The former quantity is worked out by a microprocessor (150) from readings of an engine revolution counter (122), an accelerator pedal position sensor (125) and a monitor (130) of various operating conditions.When a fault is detected (155) a limiting circuit (140) produces a signal denoting the max. permissible injection of fuel. This reduces the engine output power by an amt. which increases as a function of the operating time.

Title: Combined transmitter and receiver for optical data transmission with a defined reflection point on a coupler
Inventor: BOLZE THOMAS DR
IPC: G02B6/12
Filed: 1993-07-15
Abstract: To reduce costs in optical data transmission, only one optical waveguide is often used for both transmission directions. For further cost reduction, the monitor diode which is optically coupled to the laser diode is dispensed with according to the invention and a coupling arrangement which has a defined reflection point for a small portion of the light which is transmitted by the local laser diode and which can thus be received by the station's own receiver photodiode is instead inserted between the optical waveguide and the laser diode and receiver diode. <IMAGE>

Title: Method and device for transmitting signals received via antennas
Inventor: KAELBER WOLFGANG DIPL ING
IPC: H04B10/12
Filed: 1993-10-09
Abstract: When television and/or radio signals are transmitted from a receiving system to one or more television and/or radio sets, the TV signals are first converted to a lower frequency and then conducted to the television and/or radio sets via cables. However, the transmission lines used for this purpose exhibit an increasing attenuation with increased frequency so that the frequency range which can be transmitted via the cables is limited and not all programmes on offer can be simultaneously transmitted via cables. To provide a remedy in this case, all signals received as common-frequency frequency bands are first converted into serial frequency bands of low frequency advantageously linked together and are combined to form one wide frequency band. Following this, the frequency band is supplied to an electro-optical transducer and the optical signals are conducted to the individual subscribers, where they are converted via an opto-electric transducer back into electric signals which are either converted by means of a receiver or are supplied directly to the television or radio sets. <IMAGE>

Title: Method of inscribing plastic parts of laboratory equipment for their use
Inventor: RIEGER MANFRED
IPC: B44C1/02
Filed: 1993-10-12
Abstract: A description is given of a method of inscribing plastic parts of laboratory equipment for their use, in particular metering equipment, dispensers, microlitre hand-held pipettes, piston pipettes and bottle-mounted dispensers, polyolefins such as polypropylene and polyethylene being used in particular as the plastics. To be able to apply the inscription or scaling to the plastic parts in a simple and reliable way, such that the finished inscription is resistant to chemical, thermal and mechanical stresses, it is proposed to admix with the plastic during its preparation and/or during its further processing pigments and mineral substances as additives, reacting with the respective plastic in such a way that when the latter is subjected to laser light they bring about a high-contrast colour change at the points subjected to the said laser light, and to use conventional lasers subsequently to inscribe the corresponding plastic parts of the laboratory equipment.
Patent DE-4336813-A1 (DE)
Title: Device for load detection in an internal combustion engine
Inventor: HEIM HANS
IPC: G01F1/68
Filed: 1993-10-28
Abstract: A device for load detection in an internal combustion engine is described in which a main load signal is formed by means of an air flow rate meter. The values of the air flow rate meter signal sampled with a high-speed timing clock are linearised, summed over a segment at the ignition interval and the sum is divided by the number of samplings. By means of division by the rotational speed averaged in the same segment and an adaptation constant, the raw value of the main load signal is obtained. In parallel with this, a secondary load signal is produced from the throttle valve angle and the average value of the rotational speed determined in this way, taking into account an altitude adaptation. Usually, the main load signal is used for further processing and the secondary load signal is only switched over to when a fault occurs or under specific operating conditions. The raw load signal obtained from the main load signal or the secondary load signal is filtered in a suitable filter with a timing constant which can be switched over and is subsequently limited to a maximum value. The load signal which is thus obtained is used to control the internal combustion engine. <IMAGE>
