Patent DE-4202200-A1 (DE)
Title: Friction clutch actuator for IC engine powered motor vehicle - removes integral component of positioning control signal when sum and integral component are of opposite sign
Inventor: KOLBOWSKI JOERG DIPL PHYS DR
IPC: B60K23/02
Filed: 1992-01-28
Abstract: The clutch (5) is operated by a positioning drive (7) under the control of a rotational speed regulator (17) incorporating a two-term controller (25) whose output depends upon the deviation of engine output shaft speed (19) from a set-point (21) linked (11) to the accelerator pedal (9). The integral component (29) denoting the temporal variation of the error signal is switched out (35) by a sign comparator (33) when its polarity is opposed to that of the combination (31) of the proportional (27) and the integral components of the positioning signal. ADVANTAGE - Oscillations degrading quality of adjustment and unnecessarily loading clutch are prevented.

Title: Re-heating clean gases downstream from sulphur scrubber - comprises heating clean gases by drawing heat from initial raw gas which is pre-cooled
Inventor: FRAUENFELD MARTIN DIPL ING
IPC: B01D53/50
Filed: 1992-06-17
Abstract: Impure gases are scrubbed (9) to remove sulphur and produce clean gases. The clean gases are re-heated by the relative movement of a heat-bearing medium (1a) through passages from the incoming unscrubbed gases to the clean gases. The novelty is that the clean gases are first recuperatively pre-dried and pre-heated (5) by heat drawn from incoming raw gas, and that the pre-cooling of the raw gases regeneratively re-heats (1) the clean gases such that the temp. of the clean gases does not fall below 75 deg. C. USE/ADVANTAGE - The process maintains the temp. of scrubbed gases. The arrangement does away with the previous need to use hydrogen fluoride as a heat transfer medium and its associated technical and environmental disadvantages.

Title: Turbocharger system for IC engine of motor vehicle - includes secondary turbocharger with controlled flow by=pass to prevent sudden torque changes
Inventor: BUCHER JAKOB DIPL ING
IPC: F02B39/04
Filed: 1992-07-02
Abstract: The main turbocharger (3) has a secondary turbocharger (5) in parallel and controlled via a flow control valve (7). A by-pass line (14) shunts out the action of the secondary turbocharger to compensate for sudden switching of the latter. The switching speeds of the control valves in both sides of control are matched. The secondary turbocharger can be shut down rapidly to prevent high engine speeds or if there is a lubricant shortage etc. The turbo-charging characteristics are controlled by pneumatic control lines or by electronic control. ADVANTAGE - No sudden torque changes, improved engine control.

Title: Automatic doubler winder has separate controlled speeds - for friction drive roller and reciprocating yarn guide for variety of winding patterns
Inventor: YAMAUCHI TOSHIO
IPC: D01H9/16
Filed: 1992-07-30
Abstract: The automatic doubler winder has a control to give independent rotary speed to the motor for the friction drive roller, in contact with the winding bobbin, and the motor for the reciprocating yarn guide. The control can be set to give a variety of winding patterns. The motor for the reciprocating yarn guide is controlled according to the winding speed of the bobbin, with a correction value based on the bobbin dia. according to the winding pattern. The corrected value is added to a reference value based on the bobbin rotary speed. The rotation of the friction roller is taken as the bobbin speed, for the difference between the friction roller and bobbin speeds to be taken as the bobbin dia. The difference in the speeds of the friction roller and the winding bobbin is registered by sensors and is used as a correction value. The correction value is taken from the start value of the second sensor for the friction roller, and the result is a control input for both motors to select a variety of winding patterns. ADVANTAGE - The operation gives a variety of bobbin windings, and also has an automatic splicing facility on a break at one of the yarns. The risk of separate yarn windings is greatly reduced when winding a doubled yarn.

Patent DE-4317004-A1 (DE)
Title: Wind turbine
Inventor: LAUERMANN GERHARD
IPC: F03D3/04
Filed: 1993-05-17
Abstract: Driven by an artificially generated vortex wind (whirlwind, turbulent wind, eddying wind). Capturing the air produces an atmospheric overpressure around the vortex chamber. On the other side, sucking out produces a suction reaching into the vortex chamber. The air can flow through the nozzles at increased speed. This produces in the drum power vortex wind or even a storm, which we need to drive the rotor. When used on dike dams in the north sea, it would simultaneously be possible to hold relatively large storm tides (storm floods) at bay, and have the best wind. It would also be possible to combine a plurality of rotors by means of couplings to form a larger powerhouse. Scientists maintain that the sun supplies us with ten thousand times more energy than we humans require. So let's get down to it and make use of some of this energy; in so doing we will be kind to the environment and create new jobs. <IMAGE>

Title: Ignition coil for internal combustion engines
Inventor: BETZ DIETER DIPL ING
IPC: H01F38/12
Filed: 1993-06-01
Abstract: An ignition coil for internal combustion engines is to be designed in such a way that it has only a small variation in the functional values in mass production and has a high energy storage capability. The ignition coil has a ferromagnetic core (11) with a closed jacket core (12) and a centre leg (13) which crosses the latter and is terminated in the longitudinal direction at both ends by end parts (17). These end parts are widened like a pole shoe and partially project into recesses (24) in the jacket core (12), which are shaped in such a way that gaps (18) of constant width form towards the ends of the end parts (17). On account of the end parts (17) projecting into the jacket core (12), a large length of the gaps (18) can be realised and this means that, for a predetermined magnetic reluctance of a gap (18) provided with a shorter length, the width of said gap can be increased. The object described at the beginning can be achieved by this means. This ignition coil is preferably used in internal combustion engines of motor vehicles. <IMAGE>
