Abstract:
A method for processing a moving workpiece (1), in particular a vehicle body (1) which is moved using of a conveyor belt (10). A processing tool (5) is used which is attached to the hand (12) of a robot (7) and comprises a sensor system (18) which is permanently connected to the processing tool (5) and has at least one sensor (19). During the processing, the processing tool (5) follows the moving workpiece. This following movement is based on a closed-loop control process in which the processing tool (5) is oriented periodically towards reference areas (9) of the moving workpiece (1) using measured data of the sensor system (18). The measured data of the sensor system (18) is compared with setpoint data which is generated within the scope of a set up phase (I) of the processing tool (5), and a movement vector of the processing tool (5) is calculated from the difference between the measured values and setpoint data using a Jacobi matrix calculated within the scope of the set up phase, the processing tool (5) being moved by an amount equal to said movement vector. This process is repeated in a control loop.
Abstract:
The invention relates to N-unsubstituted imidic ester alkyl sulphates, N-unsubstituted amidinium alkyl sulphates and a process for their preparation, which is characterized in that carboxamides are converted with sulphuric diesters into the corresponding imidic ester alkyl sulphates, which are reacted further with ammonia to give the analogous amidinium alkyl sulphates.
Abstract:
N-Unsubstituted 3-chlorobenzisothiazoles are obtained by reacting N-unsubstituted benzisothiazolones with phosgene in the presence of catalysts.
Abstract:
An anti-theft device for a motor vehicle includes a key having a transponder. A lock has a keyhole for receiving the key. An antenna is in the vicinity of the lock. A control unit for controlling the antenna sends starting signals to the transponder and receives answer signals from the transponder. An assembly is turned on or off if the answer signals correspond to set-point signals. The antenna has a lighting device being controlled by the control unit for illuminating a region around the keyhole, at least before the key is inserted.
Abstract:
2-Amino-5-aminomethyl-pyridine, of the formula ##STR1## can be prepared by reacting substituted methylene-glutaconic acid dinitrile of the formula ##STR2## having the meaning of R.sup.1 as given in the general description, at from 50.degree. to 200.degree. C., initially with from 3 to 20 mol of ammonia and then, in the presence of a hydrogenation catalyst, with hydrogen. The hydrogen is present an a partial pressure of from 10 to 250 bar. The reaction can be carried out with or without solvent.
Abstract:
.beta.-Aminoacrylic acid esters can be prepared by reacting acetic acid esters of the formulaH.sub.2 CR.sub.1 --COOR.sup.2 (II)with aminal esters of the formula ##STR1## at 0.5-10 bar and 50.degree.-170.degree.

Abstract:
A sinterable, finely divided molding material and the preparation thereof are described. The molding material is composed of a vinyl chloride (graft) copolymer, at least one anionic and/or nonionic emulsifier and, if appropriate, small quantities of additives.The vinyl chloride (graft) copolymer contains 95 to 70% by weight of polymerized units of vinyl chloride, 5 to 30% by weight of polymerized units of an alkyl acrylate having 3 to 10 carbon atoms, 0 to 7% by weight of polymerized units of ethylene and 0 to 15% by weight of polymerized units of vinyl acetate.The molding material is suitable for the production of flexible, sintered moldings, in particular separator plates, for electric cells.
