Title: Vibration minimisation of material=removing machining devices - involves measurement of natural frequencies, vibration direction and cutting angle
Inventor: SEIDEL BERND DR SC TECHN
IPC: F16F15/02
Filed: 1992-09-28
Abstract: The carrier, drive and transfer elements of the machining mechanism are arranged to enable the individual natural frequencies of the machining devices caused by interaction with the machined material to be measured as a function of the cutting angle. The vibration direction is determined from the angle between the vectors of the machining devices's vibration path and of a feed speed. The cutting angle is determined from the angle between the x-axis oriented in the direction of the feed speed and the intersection line between the machining device surface and the x-y plane. USE/ADVANTAGE - E.g. for use in planing, turning, cutting and drilling of metal, plastic, ceramics, glass, rock and wood. Enables optimum machining quality to be achieved at low cost by minimising vibrations.

Title: Propulsion of the controlled front wheel in the case of single-track vehicles and tricycles by means of muscular power
Inventor: HOPPE KURT DR MED
IPC: B62M3/02
Filed: 1993-06-14
Abstract: A controlled front wheel, which is driven by the use of muscular power, in the case of single-track vehicles and tricycles, with a low seat position for the driver - approximately 40 to 50 cm above the ground and between the two axles - and where the entire propulsion mechanism is mounted on the movable front-wheel fork which forms a smaller, i.e. more oblique angle with the ground than is formed in the case of conventional two-wheelers. The combination of the propulsion mechanism which is attached to the front-wheel fork, is operated by muscular power and is concomitantly moved when steering, and with a low seat position (see above) with a more pronounced inclination of the fork with respect to the ground than is customary in the case of two-wheelers, is the new idea which has the effect that a vehicle of this type can be driven without effort and safely since the pedalling forces which influence the steering can readily be sustained at the handlebars by the driver, as described above (Figure 1). <IMAGE>

Patent DE-4326277-A1 (DE)
Title: Method and circuit arrangement for detecting the bit error rate in a digital optical receiver
Inventor: KAISER NORBERT DIPL ING
IPC: H04B10/07
Filed: 1993-08-05
Abstract: According to CCITT Recommendation G.958, there is a requirement for optical receivers to indicate if the incoming optical power level is below the power level which causes a bit error rate of 10<-3>. In solutions known to date, the optical input level quantity is inferred from a voltage measurement following the opto-electrical transduction. This method is relatively inaccurate, since the noise components of the amplifiers and possibly also an avalanche photodiode affect the voltage measurement. According to the invention, the bit error rate is determined by measuring the number of data edges within a defined time window. The edges are detected through simple logical combination of the output signals of two D-flip-flops which are controlled by two clocks which delimit the time window. The number represents a measure of the bit error rate. <IMAGE>

Title: Process for the production of brushes and brush production machine for carrying out the process
Inventor: DOERFLINGER BENNO
IPC: A46D3/00
Filed: 1993-09-07
Abstract: A brush production machine has a device (2) for feeding bristle tuft strand material or bristle tufts to a bristle-tuft mounting (7). In the bristle-tuft mounting (7) there are through-holes (9) to which there are assigned transport plungers (11) which can be inserted. The perforated plate of the bristle-tuft mounting (7), with the bristle tufts located therein, can be displaced towards a first compacting perforated plate (12) with through-holes (9a) of reduced cross-section. The bristle tufts located in the perforated plate of the mounting (7) are pressed into these through-holes with the aid of the transport plungers (11) and compacted in the process. From there, a transfer is then carried out into a further compacting perforated plate (12a) and from this into the accommodation holes of an injection mould (25). The bristle tufts can be compacted to such an extent that penetration of injected material during the connection of the bristle tufts to a brush body is reliably avoided. <IMAGE>

Title: Process for purifying waste water and/or ground water
Inventor: WEBER KLAUS DR
IPC: B09C1/00
Filed: 1993-09-28
Abstract: The invention relates to a process for the environmentally compatible purification of waste water and/or ground water polluted in particular with organic pollutants. The pollutants are wholly or partially transferred into an oxygen-containing gas by stripping the polluted water with the gas or are removed from the gas by a biofilter. The water thus treated can, in a case-specific manner, be conducted away directly as purified water or be fed to a biological waste water treatment. The stripping is preferably carried out as gas/water ratios of 10 to 250 m<3> (S.T.P.) of stripping gas per m<3> of water and at temperatures of 283 to 323 K.
