  • Patent number: 5975746
    Abstract: The invention pertains to a process for monitoring bar cutoff on CNC-controlled automatic bar lathes having a main spindle (3), an auxiliary spindle (6) and a pull-away carriage (WS3). In cutting-off operations it is necessary to monitor whether the cutting-off operation has cleanly severed the workpiece from the unmachined part. This control prevents machine damage that could arise as a result of imperfectly severed workpieces. The invention provides that after the cutting-off operation is completed, the pull-away carriage is started in the direction of a predetermined control path. In the time the pull-away carriage moves along the control path, the contour variation is monitored and compared with a value for contour variation that was defined in no-load operation, i.e. without a workpiece. If upon comparison the contour variation exceeds a predetermine threshold of difference, i.e.

  • Patent number: 5899029
    Abstract: With a support structure (30) for floor plates (32) elongated frieze members (20) meet together in the vicinity of their ends and form individual mutually connected frames (31). The frames (31) are arranged at a separation from a mounting surface (21) of the support structure (30) via spacer elements (16) and hold floor plates (32). The mutually meeting ends of the frieze members (20) have sidewardly disposed angle brace components (10, 11) by means of which the individual frieze members (20) are connected to each other in a detachable fashion with the assistance of connecting elements (15). The spacer elements (16) are attached to the angle brace components (10, 11) in an adjustable and detachable fashion. In this manner adjustment of the horizontal orientation of the floor plates (32) is also possible after complete assembly of the support structure (30). The support structure (30) is permanent and weather-resistant.

  • Patent number: 5840363
    Abstract: The invention pertains to a process for throughplating of printed circuit boards using conductive plastics for direct plating, wherein a polymer film with intrinsic electric conductivity is adhesively deposited on non-conductive areas of the printed circuit boards, whereupon a metal film is applied. Selective production of the polymer film has previously been seen as requiring an oxidative pre-treatment of the printed circuit board, though this can negatively affect the further course of the process. With the present invention the potential negative effects are avoided by forgoing the oxidation pre-treatment.

  • Patent number: 5819733
    Abstract: A transpharyngeal tube (10), especially for intubation anaesthesia, has a tube shaft (13) on which an inflatable primary cuff (18) for blocking the pharynx (19) and an inflatable secondary cuff (16) for blocking the esophagus (12) are disposed. At least one application channel (20) is formed on or in the tube shaft (13) which has an application opening (21), located below the primary cuff (18), for application of substances into the trachea (14). The secondary cuff (16) surrounds a tube tip (11) of the tube shaft (13) which seats in the entrance region of the esophagus (12) on an inner wall (15) thereof when the transpharyngeal tube (10) is inserted. This configuration of the transpharyngeal tube (10) facilitates a safe, reproduceable, and directed insertion into the esophagus (12) with which a safe and painless securing of the transpharyngeal tube (10) and controlled application of the application substance into the trachea (14) are guaranteed.

  • Patent number: 5812565
    Abstract: The invention concerns a method for the automatic recognition and correction of an invalid data set stored in a programmable circuit memory which is part of a group of at least three identical stored data sets, wherein the data sets of the group are compared to each other, and in the event that one data set of the group does not agree with the remaining data sets of the group same is recognized as being invalid and the remaining agreeing data sets are recognized as being valid, and the invalid data set is corrected through replacement with a valid data set. The invention is also directed to a system adapted to carry out this method.

  • Patent number: 5757185
    Abstract: A method of nuclear magnetic resonance (NMR) spectroscopy subjects a sample located in a homogeneous external magnetic field to a sequence of two radio frequency (RF) pulses whose strength and duration are chosen to produce an NMR signal, wherein a time and spatially variable magnetic gradient field GF is applied in a time interval between the first RF impulse exciting the NMR signal and read-out of the signal, and an electric field is applied during the excitation sequence. The magnetic gradient field GF is chosen to cause a velocity-dependent change in the phase and/or amplitude of the signals from spins moved in the direction of the magnetic gradient field GF by the electric field and changes in the signal phase and/or signal amplitude of the NMR signal due to the electric field induced motion of spins in charged, polar, or polarizable molecules along the magnetic gradient field are subsequently observed.

  • Patent number: 5726570
    Abstract: The invention concerns a NMR measuring cell, in particular one for a flow-through probe head (1) and having at least a first inlet opening (10) to introduce a first injected or pumped reaction liquid into the measuring cell (1) and a second inlet opening (11) for introduction of a second injected or pumped reaction liquid into the measuring cell (1). The measuring cell (1)is subdivided by means of an at least partially movable wall (2) into at least a first chamber (17) which communicates with the first inlet opening and a second Chamber (19) which communicates with the second inlet opening (11). The at least partially movable wall (2) is configured and adapted in such a fashion that directed motion thereof leads to a mixing together of the first reaction liquid separately stored in the first chamber (17) with the second reaction liquid separately stored in the second chamber (19). In accordance with the invention a rapid and homogeneous mixing-together of the two reaction liquids is achieved in milliseconds.

  • Patent number: 5715591
    Abstract: It is well known that induction regulators are used in transmitting signals in head drum structures in video devices or equipment for digital recording and playback of signals. Since each head on the head wheel requires its own induction regulator, or transformer for short, there can be a relatively large number of transformers. This plus the fact that head drum units are becoming increasing smaller, and transmission frequencies increasingly higher, leads to very high demands for precision on the part of the transformer. This applies both to the ferrite rings and to the coils of the transformer. A device is proposed with which coils can be produced with high precision in the inner groove of the ferrite ring.

  • Patent number: 5692016
    Abstract: Multi-channel transmission systems make great demands on the adjustment of the local oscillators in order to minimize carrier frequency variations on the transmission and reception sides. There are prior art processes and arrangements in which the local oscillators are adjusted by means of a synchronism word. The prior art processes and arrangements, however, have the drawback that the oscillators cannot be adjusted accurately enough. The present invention overcomes this drawback in that, in addition to the known synchronism symbols, other synchronism symbols are used and the synchronism symbols are evaluated with increased spectral resolution.

    Abstract: A gradient coil system for the production of a magnetic transverse gradient field G.sub.x =dB.sub.z /dx in an NMR tomograph has axial and transverse access to the measuring volume. The gradient coil system consists of four partial coils (S.sub.1x, S.sub.2x, S.sub.3x, S.sub.4x) each with two current connections (A.sub.1, A.sub.2), which are arranged mirror symmetrically with respect to the xy-plane (z=0) and mirror symmetrically with respect to the zy-plane (x=0). Each partial coil comprises winding sections on an inner and on an outer cylinder Z.sub.1x, about the z-axis as well as on a radial connecting surface V.sub.+x, V.sub.-x and the radial connecting surfaces V.sub.+x, V.sub.-x of those partial coils (S.sub.1x, S.sub.4x ; S.sub.2x, S.sub.3x,) which face each other opposite the xy-plane are essentially identical. An axial gap for free transverse access to the measuring volume remains between the partial coils.
