Title: Perforated membranes for liquid control in acoustic ink printing
Inventor: KHURI-YAKUB BUTRUS T
IPC: B41J2/14
Filed: 1990-04-17
Granted: 1996-01-09
Abstract: In accordance with the present invention, an acoustic ink printer comprises a pool of liquid ink having a free surface in intimate contact with the inner face of a perforated membrane. The printer addresses all pixel positions within its image field via substantially uniform, relatively large diameter apertures which extend through the membrane on centers that are aligned with respective ones of the pixel positions. In operation, one or more focused acoustic beams selectively eject individual droplets of ink from the ink menisci that extend across the apertures. Accordingly, the membrane is positioned and the bias pressure that is applied to the ink is selected so that the menisci essentially remain within the focal plane of such beam or beams.

Granted: 1997-02-25
Abstract: In order to obtain a ceramics-type superconducting wire, a bulk type ceramics-type superconductor or its precursor previously treated to have orientativity in its crystal structure is reduced in diameter in a state charged in a metallic pipe, thereby being elongated, and then heat treated.  In the as-formed superconducting wire, crystal orientativity of a bulk formed of the superconductor or its precursor is maintained, whereby it is possible to obtain a superconducting wire having high critical current density.  In order to further improve the critical current density, it is effective that the diameter reduction working step and the heat treatment step are alternately repeated a plurality of times.

Title: Device and process for the embossing of fine structures
Inventor: NYFELER ALEX
IPC: B29L7/00
Filed: 1990-09-24
Granted: 1994-10-04
Abstract: ABSTRACT OF THE INVENTION    A device for embossing a set of motifs having a predetermined motif interval onto a length of film utilizes a rotating embossing cylinder which is provided with a recess for the attachment of an embossing matrix.  The embossing matrix has a usable length which is less than the entire circumference of the embossing cylinder hut more than 50% of the circumference of the embossing cylinder.  A rotating counterpressure cylinder is positioned adjacent the embossing cylinder, such that the film advances between the counterpressure cylinder and the embossing cylinder for embossing said motifs from said embossing matrix onto the film and for defining a free phase during each rotation of the embossing cylinder when the recess is positioned adjacent the film.  The device also comprises movement means for providing an additional relative movement between the length of film and the embossing matrix during each free phase of the embossing cylinder.  A control mechanism determines the amplitude of the additional relative movement in accordance with the motif interval.  It is a significant advantage of the present invention that the embossing cylinder circumference is independent of the motif interval thus allowing for easy change of the embossing matrix.

Granted: 1996-04-09
Abstract: A method is disclosed for controlling the movement of hydraulically movable work equipment that is arranged at the end of a length-adjustable and pivotable arm, along a substantially rectilinear path of movement, the work equipment being moved with the assistance of hydraulic drive units that act on the arm in dependence on input control signals (in1, in2, in3) that determine the path of movement.

Granted: 1999-02-23
Abstract: A device for diagnosing the state of health of an ignition system is provided, where the system includes at least one spark producing channel comprising an exciter, output circuit and igniter plug. The device provides a diagnosis of the state of health for both the exciter and igniter plug by monitoring the high energy pulses at the output of the exciter. By monitoring the ignition system at an intermediate point in the system such as the output of the exciter, the sensor and electronics of the device may be completely contained within the electronic environment of the exciter, thereby avoiding any need for attaching sensors at the output of the system adjacent to the igniter plug in order to diagnose the plug's state of health. As an alternative to the device being built into the ignition system, it can be incorporated into automatic test equipment that produces high energy pulses for delivery to an igniter plug to be tested. The device is capable of diagnosing failure of either the exciter or the igniter plug and may also be configured to detect the impending failure of the plug.
