Patent DE-4333113-A1 (DE)
Title: Optical rangefinder
Inventor: FIEBIG ARNIM
IPC: G01S17/08
Filed: 1993-09-29
Abstract: A range finder is proposed which has an optical transmitter and an optical receiver and in which the measurement path is included in the formation of a frequency of a naturally oscillating circuit. In this case, the propogation time of the light determined the oscillator frequency, the oscillator frequency being low at a large range and the oscillator frequency being high at a short range. An up/down counter is triggered by repeated measurement and normalisation to a specific count, which counter counts upwards when measuring the measurement path and counts backwards when measuring a reference path. The difference between the values is a measure of the measurement path, which can be indicated appropriately. <IMAGE>

Patent WO-8603859-A1 (WO)
Inventor: LIEDTKE DIETER
IPC: G05G25/00
Filed: 1985-12-05
Abstract: Le procédé permettant de compenser la dérive du réglage initial due au changement des tolérances pendant le rodage d'organes soumis à l'usure, consiste à provoquer, aux endroits où se manifeste lors du rodage des changements de tolérances, une usure accrue dans un élément de compensation fait en un matériau unitaire. Cette usure accrue a pour résultat un changement de tolérances qui est opposé au changement de tolérances provoqué par le rodage. Dans un élément de compensation fait par exemple en un acier à tremper, on décarbonise, avant la trempe et à l'endroit où le changement de tolérances se manifeste lors du rodage, l'élément de compensation jusqu'à une profondeur suffisante, de façon que la dureté obtenue par la trempe est inférieure à cet endroit. Ce procédé est particulièrement utile dans un régulateur mécanique, tel que la vis de réglage de pleine charge d'une pompe à injection Diesel.

Title: Process and device for monitoring the workpiece-gripping force in machine tools
Inventor: NOSKE HEIKO
IPC: B23B31/00
Filed: 1990-11-09
Abstract: In machine tools, in particular turning machines, the workpiece being machined is held in a holder. To ensure safe operation, a certain minimum gripping force must be maintained. If this force is too small, the workpiece can be thrown out of its holder, which represents a considerable accident hazard. It should also be noted that the workpiece-gripping force decreases as the friction surfaces of the chuck become progressively less well lubricated and progressively dirtier. The invention therefore proposes that the chuck jaws act to produce a gripping force, the hydraulic energy producing this force is monitored and, when a given energy threshold is exceeded, a signal is triggered.

IPC: C01B31/02
Filed: 1994-01-27
Abstract: L'invention concerne un procédé et un dispositif permettant de produire des Buckminster-fullerènes de carbone à partir de matières premières solides contenant du carbone. Les fullerènes sont obtenus par évaporation de matériaux en vrac carbonés se présentant sous forme de matières premières composées de poussières, de granulats, de substances granuleuses ou de leurs mélanges, qui n'ont pas de forme allongée ou cuboïde marquée. Pour l'opération d'évaporation, il n'est donc plus nécessaire de faire passer des tiges ou des blocs de dimensions plus importantes, et coûteux à travers le point focal du rayonnement laser, à travers le système d'un champ inductif de haute fréquence ou comme électrodes d'arc électrique (17). L'invention permet de produire, en continu, à une échelle industrielle sur une longue période, et de manière économique, des fullèrenes, avec un équipement relativement simple, à une pression atmosphérique normalisée. Pour évaporer le carbone dans une atmosphère inerte de gaz rare, les matières premières solides contenant le carbone ou les composés carbonés sont acheminés directement dans un arc électrique, un champ inductif à haute fréquence ou bien un faisceau laser incident à l'intérieur d'un creuset (1A) ou une gaine tubulaire rempli(e) depuis l'extérieur et à remplir à nouveau avec les matières brutes contenant du carbone. Les matières premières solides contenant le carbone ou les composés carbonés sont exempts de gaz réactifs ou d'additifs comme de l'azote, de l'oxygène, de l'hydrogène ou de la vapeur d'eau. L'évaporation et l'acheminement des matières premières contenant du carbone s'opèrent dans le réacteur (1) dans un creuset (1A) semi-ouvert, haut, de type convertisseur, ou dans une gaine tubulaire destinée au carbone qui s'évapore, de manière que le refroidissement des vapeurs de carbone s'effectue lentement et que ces vapeurs se condensent sous forme de noir de carbone sur le couvercle (3) refroidi du réacteur dans un mouvement ascensionnel.

Abstract: A process is disclosed for regulating drafting equipment, in particular in carding machines. The measurement signals are sensed at the entrance of the drafting equipment, are compared with the set value and a regulating signal for the control unit of an engine that regulates the pair of drafting rollers is derived from the thus obtained differential signal. Also disclosed is a regulating device. In order to improve the regulation results and to carry out adjustments at the card sliver at the position where the difference was detected, the set values are read in a set value register (6231) by means of a transfer address, the base speed of rotation is derived from the actual speed of rotation of the doffer (631) and is retransmitted as base voltage to the driving unit of the regulating engine. A measurement cycle of lower frequency is generated depending on a roller of the drafting equipment, a measurement signal is detected during each measurement cycle, is converted into a digital signal, is compared with the activated transfer address of the set value register and a differential signal is formed. The thus obtained differential signal is converted into a transfer address for a correction register (613) and the regulating value read in the correction register by the activated transfer address is transmitted to the driving unit of the regulating engine.
