Title: Terminal emulation system
Inventor: NGUYEN NHON T
IPC: G06F13/00
Filed: 1993-07-21
Abstract: TERMINAL EMULATION SYSTEM          Abstract A centralized management system, resident upon a DOS-based personal computer, which is capable of emulating multiple cross-connect or switch management terminals. Multiple cross-connect or switch management terminals are emulated upon a centralized management system, resident upon a DOS-based personal computer. The system employs a graphical user interface which allows each of the emulated terminals to be represented as a window upon a single monitor. A user of the system can simultaneously monitor all of the emulated terminals via the windows, and issue commands controlling a selected one of these emulated terminals. The user selects the particular emulated terminal to which a command is to be issued by designating the window associated with that terminal as "current". The number, size, and/or relative location of the windows displayed may be dynamically reconfigured as needed. A given window may be minimized in size, or iconized if control of the particular switching system to which that window relates is not of primary interest, or if the particular switching system to which the window relates is off-line. In a particular embodiment of the invention, a user can access up to eight emulated terminals, and execute command scripts, command editing, command recording, log printing, and terminal performance reporting for each of the emulated terminals.

Title: Adaptive error correction control system for optimizing stirling refrigerator operation
Inventor: AUBRUN JEAN-NOEL
IPC: G05B21/02
Filed: 1993-05-28
Abstract: An adaptive control includes a digital error correction system (DECS) (51) to reduce control system error to near zero by anticipating a problem and feeding forward in time a correction to deal with the problem before it happens. The adaptive control is used in a controlled system of the kind which is cyclical in operation and which operates in response to repetitive cycle commands so that the operation of the system is substantially predictable for a significant number of cycles of operation. The adaptive control is incorporated in a refrigerator system in which two Stirling cycle refrigerators are mounted in opposition to one another. The adaptative control permits accurate control of the command waveform frequency and shape, enables the refrigerator system to be more thermodynamically efficient, and enables the two refrigerators to exactly cancel each other's vibration.

Patent CA-2126536-A1 (CA)
Inventor: KALLENBERGER HARVEY J
IPC: B23F17/00
Filed: 1994-06-22
Abstract: Disclosed is a method for machining a component using a CNC or an NC machine.  The method includes the steps of mounting the component at a location on the machine and providing a pair of datum points, e.g., "locating holes" or dowels, on the component.  A first base line is defined to extend through the datum points and a second base line is defined to intersect the first base line at an intersection.  While retaining the component at its mounting location, such component is machined using dimensions measured from the base line intersection.  The new method avoids the inaccuracies, e.g., tolerances and tolerance "buildup," that often results from the use of jigs, fixtures and the like.  In other words, the component itself becomes the reference for machining.  The method is particularly useful in making parts such as detachable, unevenly-wearing gear segments which can be turned end-for-end for greatly improved service life.

Title: Releasable clip
Inventor: KANIE HIDEKI
IPC: F16B21/08
Filed: 1994-08-23
Abstract: ABSTRACT      A releasable clip 1 which eliminates the need to align the orientation of the clip with that of a panel hole, and can  be  released  without  requiring  time  and  trouble comprises a pin 2 and a hollow bush 3 through which the pin 2 passes.  The pin comprises a head 7, a shank 8 extending from the head 7, and anchor legs 9 extending from the shank 8 toward the head in such a manner that they open radially outwardly.  The bush 3 is connected to the pin head 7 and the end of the pin shank 8 so that the bush can rotate relatively to the pin in the state that the pin shank is received therein.  When the pin 2 is positioned at a first rotational angle with respect to the bush, the ends of the anchor legs of the pin open radially outwardly so as to be able to engage with the panel or the surface of a member to be attached.   When the pin is positioned at a second rotational angle, the bush 3 engages with the ends of the anchor legs 9 of the pin.  Then, the ends of the anchor legs are brought closer to the pin shank 8 to be released from their engagement with the panel, thus enabling the clip to be detached from the panel and the member to be attached.

Title: Method and apparatus for automatically applying equalized pressure to a rotary cutting die
Inventor: STOLLENWERK JOSEF A
IPC: B26D1/143
Filed: 1994-08-24
Abstract: ABSTRACT OF THE DISCLOSURE Provided is an equalizer assembly that integrates into the die cutting station of a press and comprises two hydraulic actuators, each of which interacts with one of the jackscrews of the press to create an internal hydraulic pressure. The internal pressure of a first of the hydraulic actuators corresponds to a loading force that is imparted upon the rotary cutting die proximate to a first end of the rotary cutting die, and the internal pressure of a second of the hydraulic actuators corresponds to a loading force that is imparted upon the rotary cutting die proximate to a second end of the rotary cutting die. The hydraulic actuators are in fluid communication with one another such that the hydraulic pressures therein are maintained substantially equal to define an overall system hydraulic pressure, and the hydraulic actuators are designed and arranged so that the loading forces generated therebyare substantially equal. Therefore, in response to loading forces of the jackscrews, whether equal or unequal, the equalizer functions to automatically apply equal loading forces to the opposite ends of a rotary cutting die, whereby the rotary cutting die is evenly loaded. A hydraulic pump functions to selectively increase the system hydraulic pressure and a pressure gauge monitors the system hydraulic pressure.
