Patent DE-4204334-A1 (DE)
Title: Automatic steerage by metal track e.g. for driverless vehicle or appliance - Guiding from given place by contactless inductive coupling to determined destination using steering drive for motor with logic control unit or microcomputer
Inventor: MUENSTER HORST
IPC: G05D1/02
Filed: 1992-02-14
Abstract: The vehicle (1) is provided with a repeating coil having two windings (2/3,2/4). The windings are so arranged, with their endfaces located at a distance above the tracks (9/3) designed as a metallic strip, that the coil endfaces of the windings completely or partly correspond with the track. A resulting alteration of the sec. winding signal is used to control the steering drive (7). The vehicle can be brought to a halt by a gap in the track. Two repeating coils (2,3) can be installed in the vehicle, lying close together in the direction of travel. This remains unchanged if the repeating coil endfaces completely coincide with the track. A negative or positive difference of the sec. winding signals results if the endfaces and the track do not completely coincide. A correction of the travel direction is carried out by the steering drive, depending on the polarity of the difference of the sec. winding signal. USE/ADVANTAGE - Driverless transport system. Model car or similar. Metallic path covered can be any length and is suitable for small and large vehicles or appliances. Use of two repeating coils gives steering advantages and other design options.

Patent DE-4231713-A1 (DE)
Inventor: GRUENEWALD PETER DIPL ING
IPC: G01R31/34
Filed: 1992-09-22
Abstract: A high-frequency error signal is decoupled from a high-frequency electromagnetic field in a heavy electric machine, in particular a turbogenerator, having an electric winding (1) which extends along an axis (2), is delimited along said (2) by two winding heads (3) and through which a liquid coolant can flow. The liquid coolant flows into the winding (1) through at least a winding head (3) from a ring-shaped collecting chamber (5) arranged upstream of the winding head (3), made of an electroconductive material and connected by an earth connection (4) to the earth potential. The error signal is decoupled from the earth connection (4) of the collecting chamber (5). For this purpose, a high-frequency transformer (6) is advantageously looped-in into the earth connection (4). The invention allows spark formation in a heavy electric machine to be relatively easily detected by detection of the high-frequency field generated by a spark. A particularly efficient process for monitoring the operation of a heavy electric machine, in particular a turbogenerator, thus becomes possible.

Title: Pre-accelerator and cooler for aircraft landing gear wheels - uses precooled air and/or added water jets directed at angle onto wheels
Inventor: BLOCK HUBERT K
IPC: B64C25/40
Filed: 1992-10-02
Abstract: The landing gear wheels have air strips or pockets vulcanised at the tyre sides so that the wheels, after the landing gear extension, are given a pre-rotation in the desired direction by the slipstream. Jets of precooled air with added water are directed onto the wheels by suitable pipe and hose lines and outlet nozzles. The jets impinge prior to and during landing in correct direction onto the wheels to impart to them the desired pre-accelerating rotation and to cool them under control according to prevailing conditions. ADVANTAGE - Increased protection of wheel tyres by pre-acceleration and cooling.

Title: Drive for the plunger of a cutting press or metal-forming machine tool
Inventor: KOSMALSKI WILHELM
IPC: B26D5/18
Filed: 1993-03-17
Abstract: The problem of the invention lies in creating a very rigid cutting mechanism in which the cutting force passes approximately directly through the centre of the axes of the eccentric wheels in order to be able to provide optimum support there. At the same time, a slight spring action of the system and minimum "piercing" after the cutting-through are achieved. In this drive, an eccentric is provided for the requisite cutting stroke. This eccentric is connected to the plunger (8) via lever (6) and connecting rod (7). The deflection point of lever (6) and connecting rod (7) is connected via a strap to a further eccentric (4) for obtaining a rapid up and down movement. The solution is characterised in that the eccentric (4) and the eccentric (3) are arranged together on an eccentric spindle (1) and are also driven together by the drive eccentric wheel (2), and a linkage which is in operative connection with the free end of the strap (5) is linked to the eccentric (4). <IMAGE>

Title: Method and circuit arrangement for generating a firing pulse for a converter valve
Inventor: KRATZ GERHARD ING GRAD
IPC: H03K17/0814
Filed: 1993-07-19
Abstract: Method for generating a firing pulse for a converter valve and a circuit arrangement for carrying out the method. In order to be fired reliably, converter valves have to be driven by a control current having a characteristic which is prescribed in narrow limits. This control current characteristic has a pulse which is as rectangular as possible and a chronologically directly following holding current having a small amplitude. The method according to the invention and the circuit arrangement specified to carry it out are intended to generate the necessary rectangular pulse with as few losses as possible. The novel method for generating a firing pulse for a converter valve has two method steps running synchronously in time, a rising current edge of a sufficient gradient being produced in one method step, while a current amplitude of sufficient magnitude is produced in the other method step. The method is suitable for use in drive circuits which are usually referred to as gate units. <IMAGE>

Inventor: BEGEMANN ULRICH
IPC: D21F11/04
Filed: 1994-01-22
Abstract: Improvement of multilayer paper quality in the wet working section of a paper machine entails at least two different quality pulps for paper strip mfr.; collection and recycling of dilute suspension drained from a screen in quite separate containers where at least most of a first pulp is drained through a first screen, corresp. for a second pulp and where the suspensions from each screen are separately gathered and reintroduced to the corresp. pulp i.e. paper layer.  The appts. for the implementation comprises: appts. and pipework for gathering the separate dilute suspensions in accordance with quality levels and pipework for the re-introduction of the suspensions.  Where a two-layer strip is formed by passing two pulp layers through a continuous double-sided screen, the gathering of the different dilute suspensions is carried out mainly in the screens' initial zone. In the formation of a triple layer sheet where the dilute suspension extracted from a first screen originates essentially from the outer layers it is reintroduced to them, while that from a later screen is reintroduced to the middle layer. The outer layers (S1, S3) can originate from approx. the same pulp and enclose a middle layer (S2).
