Abstract: A drilling tool (10) for producing undercuts (36) in blind cylindrical pilot holes (17), with a drill shank (12) which roughly corresponds in diameter to the diameter of the pilot bore (17) and is connected at its tip (11) to a thrust piece (14) and can be supported on the thrust piece (14) via a sloping surface (13) and also has a lateral cutting edge (15) which projects radially beyond its outer periphery, produces the undercut (36) when it is acted upon axially and is flattened relative to the drill shank (12) to an extent enabling it to be inserted into the pilot hole (17), in which arrangement the thrust piece (14) is fastened directly to the sloping surface (13) of the drill-shank tip (11) in such a way as to be radially movable by means of an undercut guide groove (71) parallel to the sloping surface, in which guide groove (71) an undercut-strip-shaped coupling projection (72) engages axially in a positive-locking manner, and the thrust piece (14) has a sliding surface (73) which is arched transversely to the radial direction of movement of the lateral cutting edge (15) and on which the likewise arched sloping surface (13) of the drill-shank tip (11) can be supported. In order to improve a drilling tool (10) of the type mentioned at the beginning in such a way that the strength of the connection between the drill-shank tip (11) and the thrust piece (14) is adequate even in rough operation, in other words so that the connection is sufficiently stable, the drilling tool (10) is designed in such a way that the coupling projection (72) is attached to the drill-shank tip (11), and the guide groove (71) is located in a thrust piece (14) with semicircular-like arching of its sliding surface (73). <IMAGE>

Abstract: In this process, the partial esters of titanium formed upon reaction of titanium tetrahalide with alcohols in a molar ratio of 1 : (2 to 4) in the absence of acid acceptors are prepared in a first process step by introducing the reaction products in the molar ratio mentioned together with a solvent continuously into a first reactor in which the reaction components are boiled continuously. The reaction product formed is discharged continuously from the bottom of this first reactor and transferred to a further esterification reactor in which it is still continuously boiled. The hydrogen chloride liberated in these two esterification reactors is discharged, and the resulting partial ester from the second esterification reactor is alternately transferred to two or more neutralisation reactors, into which in each case the alcohol necessary for the reaction and the acid acceptor are additionally introduced. During the workup known per se of the ortho ester from the first neutralisation reactor, the reaction product from the esterification reactor is transferred to the second neutralisation reactor and processed there in the same manner as in the first neutralisation reactor.

Title: Manufacture of nozzles for ink jet printers
Inventor: PATON ANTHONY DAVID
IPC: B41J2/16
Filed: 1988-09-15
Abstract: A method of manufacturing one or more nozzles (13) for an ink jet printhead initially comprises bonding a nozzle plate (14) to the ink ejection end of the printhead (16). A mask (12) is then secured in contact with the nozzle plate (14), the mask having a plurality of apertures (15) each defining a respective nozzle exit. Laser radiation applied to the mask exposes the areas defined by the apertures to ablate the plate material between the nozzle exits on the external surface of the plate and corresponding nozzle inlets on the opposite surface of the plate. The assembly comprising the printhead (16), plate (14) and mask (12) is rocked during the exposure step to increase the area of the nozzle inlet relative to its outlet. Also, prior to the nozzle formation step, one or more ink troughs (22) may be provided for supplying an external source of ink for each nozzle. The ink troughs (22), which may be formed using laser ablation techniques similar to those used in the formation of the nozzles, facilitate a continuous, positive flow of ink through the nozzles.

Patent EP-0292426-A2 (EP)
Inventor: SCHMALL KARL-HEINZ
IPC: G01B7/312
Filed: 1988-04-25
Abstract: The device has at least three identical receiver coils (3, 5, 6) in each case on two annular support discs (1, 2) in two separate planes perpendicular to the reference axis (R). The receiver coils (3, 5, 6) are spaced from the reference axis (R), and twisted about the latter with respect to one another. One transmitter coil (9) serves to generate a high-frequency field which is symmetrical with respect to the reference axis (R) and induces identical voltages in all receiver coils (3, 5, 6). A rotationally symmetric electrically conductive body (7) inserted in the receiver coil arrangement does not disturb the symmetry of the high-frequency field only if it is precisely coaxial with the reference axis (R). When the body (7) is not precisely centred with the reference axis (R) in the plane of one of the support discs (1, 2), the voltages induced in the receiver coils (3, 5, 6) of this support disc are not identical. The induced voltages are compared with one another in an evaluation circuit. Output signals of the evaluation circuit indicate not only the eccentricity of the body (7) in one plane, but also the eccentricity in the second plane or the inclination of the body (7) with respect to the reference axis (R). <IMAGE>

Abstract: In a method to correct path and position of a robot tool (W), an actual position (P') deviating from the desired position (P) by the vector (X) is measured at discrete points (P0...P4) in the entire working range of the robot. In this arrangement, only the number of points (P0...P4) which is necessary with the utilisation of the symmetry conditions of a respective reference coordinate system (X, Y, Z) is measured. The deviations (X) measured are stored as elements of a position-error space matrix in a storage medium to which the robot control has access. During the offline or online calculation of a respective tool position, all deviations (X) in the working range of the robot are determined by interpolation of the deviations (X) at the measurement points (P0...P4) and allowed for by compensation when setting the robot joints. <IMAGE>

Abstract: The invention relates to a method for the continuous stretching of metal strips, according to which the respective strip runs through a set of braking rollers and a set of tension rollers and, in the course of its stretching in the plastic range, is subjected between the two sets of rollers to a stretching tension which corresponds to the yield strength of the strip material. In a pair of tension-stretching rollers inserted between the set of braking rollers and the set of tension rollers, the strip is subjected only to the stretching tension required for stretching it in the plastic range. The transverse strain in the course of the plastic stretching is thereby minimised, with the result that central troughs or, in the case of longitudinal strip division, lateral edges of unequal length no longer occur.
