Patent EP-0294638-A3 (EP)
IPC: D21F5/04
Filed: 1988-05-21
Abstract: Die Erfindung bezieht sich auf eine blasmittelgespeiste 
Tragfflächendüse zum berührungslosen Führen von 
Materialbahnen, die vor allem in der Trockenpartie einer 
Papiermaschine einsetzbar sein soll. Insbesondere bezieht 
sich die Erfindung auf eine kombinierte 
Doppeltragflächendüse mit Spreizwirkung. Bei einer 
Doppeltragflächendüse sind nebeneinander zwei Kammern 
30a,30b angeordnet, deren der Materialbahn zugekehrte 
Wand 18a,18b konvex gekrümmt ist und als Tragfläche für 
die Materialbahn 1 dient. An den benachbarten Rändern 
der Tragfläche sind Düsenschlitze 17d,17e für das 
auszublasende Blasmittel vorgesehen, während in den von den 
Düsenschlitzen 17d,17e entfernt liegenden Bereichen der 
Wände 18c,18d eine Perforation A vorgesehen ist, über die 
Blasmittel in die Kammern 30a,30b angesaugt werden kann. Die 
Zufuhr das Blasmittels zu den Düsenschlitzen 17d,17e erfolgt 
über einen Injektorkanal 17, dessen Eingang zu den Kammern 
30a,30b offen ist und vor dessen Eingang blasmittelgespeiste 
Injektordüsen 15 angeordnet sind. Durch die Rückführung des 
Blasmittels über die Perforation A und die Kammern 30a,30b 
verbraucht die Tragflächendüse nur ein Bruchteil an von 
einer Blasmittelquelle zugeführtem Blasmittel wie 
herkömmliche Tragflächendüsen. Wegen des dadurch bedingten 
geringeren Anfalls an zu- und abzuführendem Blasmittel sind 
die Zufuhrkanäle klein und die sonst üblichen Abfuhrkanäle 
werden nicht benötigt. Aufgrund ihrer geringen Baugröße 
eignet sich die Tragflächendüse vor allem zum Einsatz in der 
Trockenpartie von Papiermaschinen zum stabilen, 
flatterfreien Führen der Papierbahn und zur 
Vergleichmäßigung des Trockenvorgangs über die 
Papierbahnbreite.

Title: Process and device for controlling the concentration of noxious matter in the exhaust gases from combustion engines
IPC: G01N27/416
Filed: 1988-05-26
Abstract: A method and a device (10) for monitoring the concentration of noxious matter in the exhaust gases of Otto engines is proposed in order, by overall exhaust gas analysis, to determine the quality of combustion. Using an exothermic process over a heated catalyst and subsequent measurement of the air index at a temperature-controlled lambda probe, the difference between the thermochemical state of the raw exhaust gases prior to afterburning and the state of chemical equilibrium is determined. The ratio of the entropy alteration of the raw exhaust gas relative to the entropy alteration of the air/fuel mixture upon combustion overall gives a measure of the quality of combustion. <IMAGE>

Abstract: A dual temperature sensing device has a twin well 
thermowell, for installation through a penetration in a 
pipe wall, and includes a head, shank and tip portions. 
The shank portion has a first part of substantially the 
same outer dimensions as the penetration; the head portion 
is of greater outer dimensions so as to define an annular 
ledge which overlies the exterior surface of the pipe wall, 
for welding same thereto. A pair of bores extend from the 
outer surface of the head portion at angularly inclined and 
converging relationship to closely spaced, but physically 
separated, positions in the tip portion. The head is 
counter-bored relative to the first bores, to define 
sockets for receiving the lower ends of pipe nipples, the 
upper ends of which are closed by pipe unions. Dual 
resistance temperature detectors are used with elongated 
sensors extending through the respective bores to the tip 
portion of the thermowell. The detectors are both electri­
cally and physically separated, and, produce identical, 
dual temperature indicating outputs.

Title: Microprocessor controlled universal video monitor
IPC: G09G5/00
Filed: 1990-04-18
Abstract: A microprocessor controlled video monitor is presented. 
The video monitor is able to automatically adjust the values 
of its parameters to adjust to operation on a number of 
different computer systems. The video monitor includes 
control lines (35-39,43,53-60), digital-to-analog converters 
(3,45) and a control processor (1). The control processor 
(1), through the digital-to-analog converters (3,45), 
controls the values of the parameters of the video monitor. 
Stored in a non-volatile memory (2) are entries which 
contain values of video monitor parameters. The control 
processor (1) recognizes different computing systems on the 
basis of the frequency and polarity of horizontal and 
vertical synchronization signals. When either frequency or 
polarity of either the horizontal or vertical 
synchronization signals changes, the control processor (1) 
will search the non-volatile memory (2) for an entry in 
which values stored for both the frequency and polarity of 
both the horizontal and vertical synchronization signals 
matches the currently measured frequency and polarity of the 
horizontal and vertical synchronization signals. If a match 
is found the values for the parameters stored in the entry 
are applied by the control processor (1) through the 
digital-to-analog converters (3,45) to the control lines 
(35-39,43,53-60). A user may adjust certain parameters 
through the use of switches (183,184,185) which are 
periodically polled by the control processor (1). When the 
 
 
control processor (1) receives instructions from a user 
through manipulation of the switches (183,184,185) the 
control processor (1) makes the specified changes to the 
video monitor parameters and stores the new values in non - 
volatile memory (2).

Patent EP-0480597-A3 (EP)
Title: Phase lock loop
IPC: H03L7/08
Filed: 1991-09-24
Abstract: A complementary metal oxide semiconductor, single, phase-lock loop decoding apparatus allows extraction of a clock signal from Manchester-encoded data. A filter couples a phase-frequency detector to a voltage-controlled oscillator. Output of the voltage-controlled oscillator is fed back through a scaling circuit to the phase-frequency detector which is used to lock on to the reference signal. First, the reference signal is provided from an established reference frequency from a crystal-controlled oscillator having 0.01% resolution. A multiplexer selects the external clock reference in response to a select signal and directs the clock signal to the reference input of the phase-lock loop. The phase-lock loop is operated to lock onto the reference voltage. The phase-lock loop has a narrow bandwidth, fast acquisition time because of time constants established by the filter and the voltage-controlled oscillator. Upon receipt of a Manchester-encoded signal, the preamble portion of the signal is selected by use of the multiplexer and directed to the reference input of the detector. The phase-lock loop, in response to a control signal, suspends operation at a known transition until a corresponding transition in the preamble occurs. The phase-lock loop is started in a synchronized fashion with the reference signal and has a nominal frequency equal to that of the phase-lock loop. Therefore, the phase-lock loop is able to accurately track and lock onto the reference voltage within the few bit times of the preamble even though it has the narrow bandwidth. Thereafter, decoding data by use of an extracted clock, 5 MHz components of the data will not appreciably affect the operation of the phase-lock loop allowing accurate decoding of the signal. By completion of data, the multiplexer reselects the reference in anticipation of receipt of another data packet. The phase-frequency detector is sensitive to both phase and frequency and use of a charge pump in the detector allows operation of the phase-lock loop to be halted without appreciably affecting voltage levels into the voltage-controlled oscillator without adversely affecting any timing circuits such as one-shot timers used in the decoding circuit.

Title: Variable-speed ac drive utilizing a short-circuit-rotor polyphase induction motor
IPC: H02P27/02
Filed: 1991-02-13
Abstract: It includes a three-phase asynchronous motor (MAT) with two stator windings each connected respectively to controlled diodes (Ri,Si,Ti) which provide the amplitude of the wava choking controlled by speed regulators (RV1, RV2) through the modulators (M1, M2) whose intervention is determined by the signal of a speedometer dynamo (DT) through the speed regulator (RV) and the acceleration/deceleration regulator (RAD). So it is possible, having set a speed of the motor ranging between zero and a speed close to the synchronism, to keep this value constant reacting actively and passively to every variation of the torque of the machine. Because of the great flexibility of operation, the recovery of energy during the phase of braking, the absence of the expensive part relevant to the DC generation in one case and to the AC at variable frequency in the other case, this drive shows itself really competitive with respect to the drives of the known technique both DC and AC. <IMAGE>
