Title: Telephone modular jack
Inventor: KANADA HIROSHI
IPC: H01R24/58
Filed: 1988-03-08
Granted: 1991-12-24
Abstract: ABSTRACT  A telephone modular jack includes a base for receiving thereon a contact block carrying an array of spring contacts, the corresponding number of terminal units, and a cover, all mounted downwardly upon the base to be capable of being assembled by an automated technique.  Each of the terminal units has a lug which is press-fitted to each one of lead tabs extended from the spring contacts when the contact block is mounted on the base.  Each spring contact has a first end portion, a middle portion, and a second end portion, the portions being bent with respect to the others.  The contact block includes a upright support and a horizontal support in parallel with the base.  The middle portion of each spring contact is molded in the upright support in such a manner as to project the first end portion from the top of the upright support diagonally downward to the base, while the second end portion extends through the horizontal support and projects therefrom to define the lead tab at its end.  With the provision of the uniquely configured spring contacts and the contact block, the contact block can be mounted on the base so as to effect the press-fit engagement between the spring contacts and the terminal units while positioning the spring contacts to have their leading edges oriented upwardly, thereby making it possible to assemble the cover on the base in the same direction as the contact block and the terminal units.

Title: Vertical louver blind having clutched operating mechanism
Inventor: JOHN JULIUS F
IPC: E06B9/36
Filed: 1988-11-18
Granted: 1992-06-23
Abstract: ABSTRACT OF THE DISCLOSURE       A venetian blind of the vertical louver type includes an elongated  guide  track  and  a  plurality  of  louver  carriers supported by the guide track for traverse between open blind and closed blind conditions.  Each of the louver carriers supports a louver in generally vertical orientation for traverse with the carrier and for rotation about its longitudinal axis between open and closed louver positions.   A louver operating mechanism is supported on one end of the guide track and is operative to rotate the louvers to open louver positions prior to traverse along the guide track from a closed blind condition to an open blind condition.   A rotation rod extends longitudinally of the guide track in cooperative relation with the louver carriers and supports a rotation pulley actuated by a beaded chain to rotate the rotation rod and effect rotation of the louvers.  A pullcord is operative to traverse the louvers along the guide track and cooperates with a spool member which is connected to the rotation pulley through a clutch arrangement such that actuation of the pullcord to traverse the louvers to an open blind condition first rotates  the  louvers  to  open  louver  positions.    The  clutch arrangement enables rotation of the rotation pulley so as to selectively  rotate  the  louvers  without  actuating  the  spool member.

Title: Cycloconverter control system with var regulator
Inventor: HILL WALTER A
IPC: H02P27/06
Filed: 1989-02-23
Granted: 1992-04-28
Abstract: Case 3019 CYCLOCONVERTER CONTROL SYSTEM WITH VAR REGULATOR            ABSTRACT OF THE DISCLOSURE A control system for a cycloconverter fed synchronous motor drive system has an input which provides a signal representing a desired speed.  This is compared to an actual speed signal and the difference is a signal representing a desired torque. An absolute value of the signal representing desired torque is proportional to a desired current which will produce the desired torque and this is used by a function generator to obtain a signal representing load angle.  A VAR regulator receives signals from sensors on the stator windings of the synchronous motor, and the signals it provides represent the voltages and currents for each phase.  From these signals the VAR regulator obtains a representation of motor VAR.  The signal which represents motor VAR is integrated and limited to provide a load angle correction signal.  The load angle correction signal is summed with the load angle signal to provide a corrected load angle signal. A sensor provides a rotor position signal which is summed with the corrected load angle signal to provide a signal representing flux angle.  A vector rotator receives the signal representing flux angle and the signal desired current and it provides control signals to the cycloconverter to control its operation so that the stator current which it provides is at right angles to the stator flux over a wide operating range.  The control system may reduce the load angle correction signal at low stator currents because the signals representing stator currents tend to become inaccurate at low current levels, and the load angle correction signal is partly based on these stator current signals.  The control system may also provide a closed loop stator voltage regulator for controlling exciter current provided to the rotor windings.

Abstract: ABSTRACT OF THE DISCLOSURE         In attempting to upgrade crude oil to pipeline quality, it often proves necessary to treat the oil in more than one apparatus.  A simple solution to the problem is to provide an apparatus including a flashing section coupled to a treating section in which the crude oil is desanded and dewatered.  The flashing section heats the oil to a temperature in which water can exist only as a vapor, and the vapor thus generated is discharged through a demister.

Title: Excitation stage for gas lasers with a multi-channel pseudo spark gap and use of the excitation circuit
Inventor: BRUECKNER VOLKER
IPC: H01S3/097
Filed: 1989-04-26
Granted: 1992-10-06
Abstract: Abstract of the Disclosure:          An excitation circuit for TE lasers serves to generate a homogeneous high pressure glow discharge between laser electrodes within a gas space of a laser chamber.  A fast acting high voltage switch of a pulse forming network is a multi-channel pseudo-spark switch and is preferably integrat-ed with the laser.  The switch is formed of a parallel circuit including a number of individual pseudo-spark switch-es with gaps, is in particular insulated from all of the other anodes and for this reason it can be controlled sepa-rately.  In contrast thereto, the cathode is common to all of the individual pseudo-spark switches.  The separate, metallic anodes are located in a common insulating body, which is an anode holder.  Slots are formed within the anode holder, between metallic anode inserts.  The anode holder is separat-ed from the cathode by an insulating body, which is a main insulator and is separated from the cathode by a predeter-mined distance.  The total multi-channel pseudo-spark switch is filled with an ionizable low pressure gas filling at a given pressure.  Voltage is applied to the anode and the cathode in such a way that the resulting gas discharge is located on the left-hand branch of the Paschen curve.  The switch of the excitation circuit can also be used as a separate structural element for triggering an electrical high voltage switch circuit, and also for so-called flat plane laser systems.
