Title: Drawing die with displacement head
Inventor: LENK ERICH
IPC: D01D4/06
Filed: 1992-04-16
Granted: 1995-10-11
Abstract: A drawing head 1 with drawing chamber 2 which, at the top, is delimited by a plate 3 for feeding the molten mass with a channel 8 for feeding the molten mass on the contour by means of the nozzle casing 13, and is delimited towards the bottom by a rectangular nozzle plate 4 with the drawing channels 15 and drawing holes 16, and is characterised by the form of a displacement body 5 for deviating the drawing mass in the nozzle chamber 2. This form equalises the different pressure drops due to flowing paths of different lengths. As a consequence, the uniformity of the gauge of the drawn filaments is greater than that found with known rectangular drawing dies. (Figure 1)

Patent IT-1250482-B (IT)
Title: System for conversion of electric energy using multilevel inverter
IPC: H02M/
Filed: 1991-06-21
Granted: 1995-04-07
Abstract: The technological sector addressed by the invention is that of the static conversion of electric energy. The technical problem is that of reducing the harmonic content of the output wave form of the DC/AC converters (inverters). For this, the invention presents a multilevel structure, that is, with several levels of output phase voltage instead of the two levels that can be obtained by the most widespread inverters in the industry. Having a larger number of levels to be combined by an appropriate PWM modulation technique in order to better reconstruct a sinusoidal wave form, it is possible to achieve significant improvements in the output voltage and current spectra. Such a structure is multiphase, modular, without inductive couplings, and it allows less voltage stress on the electronic switches comprising it and a simplified design of the static and dynamic snubber circuits. The end use concerns all fields of use of DC/AC and AC/DC/AC conversion systems, such as electrical actuations, electrical systems, continuity assemblies, power conditioning systems, etc. <IMAGE>

Title: Method for preparing cyclohexylamine
Inventor: CHEN YN-TZWU
IPC: B01J23/75
Filed: 1996-06-06
Granted: 1997-03-11
Abstract: The present invention is related to a method for preparation of cyclohexylamine by hydrogenating aniline at a temperature of 150 to 250 deg.C under a hydrogen pressure of 1 to 20 atm in the presence of a catalyst selected from a chromium- or thorium- modified cobalt boride, in which the amount of the modified cobalt boride is at least 0.6 wt% based on the weight of aniline. Compared with the prior art which used a conventional hydrogenation catalyst such as ruthenium, palladium, Raney cobalt or Raney nickel, the method adopted by the present invention has the advantages in that it can be performed under a relatively lower hydrogen pressure without necessity of adding any coupling inhibitors and a much higher aniline conversion and a higher or comparable selectivity to cyclohexylamine can be obtained, thusresulting in greatly increased yield of cyclohexylamine.

Title: Method and apparatus for processing time domain cross-talk information
Inventor: JEFFREY S BOTTMAN
IPC: H04B3/46
Filed: 1996-11-30
Granted: 1997-07-11
Abstract: A pulse-based LAN cable test instrument that processes time-domain cross-talk measurement information in order to troubleshoot and locate sources of cross-talk in a LAN cable system is provided. A pulse-response time record between a pair of transmission lines of the LAN cable system is first acquired. A series of steps to process the time-domain pulse response data in the time record are then performed to enhance the ability of the user to locate and troubleshoot the primary contributors to NEXT along any point of the LAN cable system. The pulse response data are first normalized as a function of distance from the LAN cable test instrument in order to compensate for losses along the LAN cable. Next, the pulse response data are integrated over the time record and the absolute value of the pulse response data is calculated to more clearly show the individual sources of cross-talk within the overall LAN cable pulse response. Finally, the pulse response data are scaled such that the areas of the LAN cable system causing a failing NEXT indication rise above a limit level on the graph to provide a fast visual determination of the sources of cross-talk for troubleshooting purposes.
