Patent EP-0235955-A3 (EP)
IPC: H04B10/00
Filed: 1987-02-03
Abstract: This invention is concerned with materials for nonlinear 
optical devices for the conversion of optical energy at one 
frequency to optical energy at another frequency.  
     Laser techniques have been developed to a great extent 
and it is possible to obtain various kinds of laser light by utilizing 
solid, gas, and liquid media. Laser light having various 
wavelengths is often desired and in some cases, a laser light 
exhibiting a continuous spectrum over a certain range of 
wavelengths is desired. One means for converting coherent laser 
light of a fundamental frequency into laser light of a wavelength 
having a frequency twice the fundamental frequency (i.e., the 
second harmonic) involves passing the laser light through a 
nonlinear optical crystal.  
     This invention involves devices for and method of generat­
ing coherent second harmonic light radiation. The devices com­
prise a laser source of coherent light radiation at a fixed funda­
mental frequency, a Schiff base compound, means for directing 
the output radiation of the laser onto the Schiff base compound, 
and output means for utilizing the second harmonic frequency. 
Preferably, one moiety of the Schiff base compound has a 
hyperpolarizable group and the other moiety of the Schiff base 
compound has a configuration so that the compound crystallizes 
in a non-centrosymmetric configuration.

Patent EP-0261838-A3 (EP)
IPC: G07D1/00
Filed: 1987-09-10
Abstract: In a gaming or amusement machine coins are 
dispensed from a stack tube (1) by a payout slide (6) 
which moves horizontally to push the bottom coin (10) 
into an ejection chute (11). In contrast to previous 
arrangements, the coins are stacked on edge, one above 
another in the stack tube (1) which takes up less 
space in the machine than conventional, cylindrical 
stack tubes in which the coins are stacked flat. The 
stack tube (1) may be formed conveniently by machining 
a groove (2) in the side wall (3) of the machine and 
by attaching a flat strip (4) to the wall (3) to close 
off the groove (2).

IPC: F02M57/02
Filed: 1987-11-04
Abstract: A diesel unit fuel injector includes a pump 
assembly having an externally actuated pump plunger 
(4) reciprocable in a bushing (3) which with the pump 
plunger defines a pump chamber (14), with flow 
therefrom during an injection cycle portion of the 
pump stroke being directed to a fuel injection nozzle 
assembly. The injection nozzle assembly includes a 
needle type differential area injection valve (91) 
that is normally biased to a valve closed position by 
a valve return spring (97) which is positioned in a 
spring cavity (103) and which is operatively 
connected to the opposite end of the needle injection 
valve. Passage means (51,37,102), including orifice 
passages (100,101), are used to direct spill flow 
from the pump chamber at the end of an injection 
cycle to the spring cavity to effect closure of the 
needle injection valve at a valve closing pressure 
which is greater than the valve opening pressure so 
that the pressure of the discharge of fuel at the end 
of an injection cycle is relatively great whereby to 
effect increased penetration of the discharged fuel 
into the associate combustion chamber of a diesel 
engine.

Title: Chromatic dispersion measuring system for optical fibers
IPC: G01N21/41
Filed: 1988-02-26
Abstract: A system for measuring a chromatic dispersion of an 
optical fiber based on a baseband phase comparison 
method has an optical signal transmitter (20), a 
reference optical fiber (61), a measurement optical 
fiber (62), and an optical signal receiver (40). The 
transmitter has  n  light sources (25) for selectively 
generating, as measurement optical signals, optical 
signals having wavelengths corresponding to  n  wavelength 
points to be measured. One of the  n  light sources (25) 
also serves to generate a reference optical signal. The 
transmitter (20) further has an optical switch (26 and 
27). The optical switch (26 and 27) has  n  optical 
signal inputs arranged in correspondence with the  n  
light sources (25), a measurement optical signal output, 
and a reference optical signal output. The optical 
switch (26) commonly outputs, to the measurement optical 
signal output, the measurement optical signal which is 
output from the designated one of the  n  light sources 
(25) and is selectively input to the  n  optical signal 
inputs. The optical switch (27), which is a half mirror 
(27), is provided for outputting the reference optical 
signal generated by one of the  n  light sources (25) 
to the reference signal output. The optical signal 
receiver (40) is coupled to the reference optical 
fiber (61) and the measurement optical fiber (62), and 
receives the reference optical signal from the reference 
optical fiber (61) and the measurement optical signal 
from the measurement optical fiber (62), respectively, 
for measuring chromatic dispersion. The receiver (40) 
includes a plurality of programmable optical attenuators 
(41 and 42).

Abstract: Zum Überwachen der Preßkräfte der paarweise 
wirksamen Ober- und Unterstempel einer Tablettenpresse, 
mit der ein aus aufeinanderfolgenden 
Meßergebnissen gebildeter Mittelwert mit zwei 
einstellbaren Toleranzgrenzen (G) verglichen 
wird, sind bei bekannten Verfahren dem Mittelwert 
(A) zwei einstellbare Einzelwertgrenzen 
(B, C) zugeordnet, mit denen die Maxima der 
Einzelwerte der Preßkräfte verglichen werden. 
Mit einer derartigen Einrichtung und diesem 
Verfahren lassen sich jedoch nicht einwandfrei 
rechtzeitig gewisse Ursachen von Betriebsstörungen 
erkennen, da beispielsweise eine leichte 
Beschädigung eines einzelnen Stempels den Mittelwert 
nicht wesentlich ändert. Hinzu kommt, 
daß der Toleranzbereich verhältnismäßig weit 
gewählt werden muß, um ein häufiges Stillsetzen 
der Tablettenpresse zu verhindern, ohne daß 
besondere Betriebsstörungen vorliegen. Um dem 
abzuhelfen ist nach der Erfindung vorgesehen, 
den einzelnen Stempelpaaren (1, 2) sogenannte 
Stempelpaarmittelwertgrenzen (S u , S o ) zuzuordnen, 
mit denen der jeweilige Stempelpaarmittelwert 
(S) verglichen wird und zwar vorzugsweise
