IPC: F24F12/00
Filed: 1980-11-18
Abstract: Bei diesen Wärmetauschern (1) mit feststehenden Aus­
tauschflächen, in einer Einrichtung zur Wärmerückgewin­
nung durch Luftaustausch, insbesondere der zur Zuluft in der 
Temperatur höheren und in entgegengesetzter Richtung 
strömenden Fortluft, sind diese beiden Luftmassenströme 
von einer Vielzahl einander benachbarter und in Richtung 
der Luftmassenströme verlaufender, wärmedurchlässiger 
Flächenelemente voneinander getrennt, die aus Blechen, 
Folie, Profilteilen, Spritzteilen oder Sinterteilen, teils aus 
metallischen oder teils keramischen Werkstoffen oder aus 
Kunststoff hergestellt sind, und die mäander-, sägezahn-oder 
spiralartig endlich oder endlos geformt sind und den Luft­
massenströmen eine größtmögliche Oberfläche gegenüber­
stellen, zur Erzielung eines hohen Wärmerückgewinnungs­
grades. Durch eine düsenartige Verengung der Luftschleu­
sen (3 und 4) in Richtung der Luftmassenströme wird ein 
Höchstmaß an Wirkungsgrad erzielt.  
     Diesen Wärmetauschern (1), die sowohl unmittelbar in 
entsprechende Geräte oder in die Wände (16) von Wohnhäu­
sern und vergleichbaren Anlagen eingebaut werden können, 
können zur Steuerung der Luftmassenströme in den Luft­
schleusen (3 und 4) Ventilatoren (17) und/oder zusätzliche 
Luftschleusen (19, 20), sogenannte Bypässe, zugeordnet 
werden, die über Steuerklappen (21) stufenlos regelbar zu 
bzw. abschaltbar sind.
Patent EP-0030740-A3 (EP)
IPC: F21V11/00
Filed: 1980-12-17
Abstract: A light fixture comprising parabolic reflector segments 
therein, the lamp being located at the focal point of the seg­
ments. One segment has an arc preferably more shallow than 
the other segment. The window opening is angled preferably 
at an angle of 60 degrees to the elongate axis of the parabolic 
segments to provide sharper light cutoff or less spill light from 
one reflector segment than from the other. A shield 
positioned parallel to the elongate axis and on the side of the 
axis within the reflector segment where the cutoff characteris­
tics are the greatest, permits primary reflected light from the 
lamp, while preventing direct light from the lamp to pass 
above the shield. The specular underside of the shield 
enhances light reflection therefrom while the darkened top 
shield surface blocks secondary reflection above the cutof 
angle.

Title: Apparatus for answering telephone calls automatically
IPC: H04M1/65
Filed: 1981-12-16
Abstract: For switching over from playback of the owner's announcement text to recording a message from a caller, a pause of defined length is present on the announcement tape between the first and second (or end) parts thereof. This pause is recorded and on every run of the announcement tape through the apparatus the reading, recorded for the length, undergoes comparison with the pause of the announcement tape being transported. When the two values are the same, switch over takes place. In this way, it is possible to make certain of switch over without being dependent on the tape speed, and the circuit system may be made very much less complex.

Patent EP-0056303-A3 (EP)
IPC: G01B7/30
Filed: 1982-01-07
Abstract: A position sensor for sensing the angular position of an 
oscillatory member such as a transducer, includes a magne­
tic element (24) which is permanently magnetized in a pre­
determined direction and forms part of the oscillatory 
member for oscillatory movement therewith. A Hall plate 
sensor (36) is positioned adjacent the magnetic element (24) 
to detect changes in the magnetic field presented thereto by 
changes in position of the magnetic element. When the 
magnetic element is oscillated with the transducer, the 
magnetic field presented to the Hall plate is varied accord­
ingly. This, in turn, produces an electrical signal as an 
output of the Hall plate which is a function of the instanta­
neous position of the magnetic element and hence of the 
oscillatory transducer. That electrical signal may then be 
used to produce synchronization signals for the imaging 
apparatus of the transducer.

Patent EP-0082628-A3 (EP)
IPC: G03D3/06
Filed: 1982-12-07
Abstract: In the processing of light-sensitive media, for example 
lithographic printing plates, the active components of the developer 
are used up and need replenishment, particularly when silver halide or 
similar technology is involved.  
     The modulation signal of a laser used to expose the 
light-sensitive media is integrated to provide a signal indicative 
of the exposed image area to be developed and this signal is used to 
control the addition of replenishment material. Replenishment 
required to overcome the degradation of the active components with 
time may also be incorporated. In a preferred embodiment of a 
replenishment control circuit a laser beam modulator 31 supplies a 
modulation signal to an integrator comprising a high output 
frequency sampler 32, a counter 33 and a laser-on counter 34a. A 
developer circulating pump 35 and a replenishment pump 36 are 
controlled by a microprocessor 34 which contains the laser-on 
counter 34a and a replenishment dose required counter 34c fed by the 
counter 34a and a time base generator 34b which provides a purely 
time-dependent component of the replenishment required count. A 
replenishment dose control counter 34d controls operation of the 
pumps 35 and 36 in dependence upon the content of the dose required 
counter 34c.

Title: Fiber optic dye amplifier
IPC: H01S3/23
Filed: 1984-08-20
Abstract: A fiber optic amplifier is disclosed, comprising a fiber optic, monomode waveguide (20) having a core (64) and cladding (66). A portion (70) of the cladding (66) over a predetermined region is removed and replaced by an active medium (30) capable of absorbing light energy at a first wavelength and emitting light energy at a second wavelength. The active medium (30) is a lasing dye that has an index of refraction adjusted to be slightly less than the index of refraction of the fiber core (64). The amount of cladding (66) removed is adjusted such that a predetermined amount of penetration of the evanescent field from a pump light signal (36) coupled into an end of the fiber (20) penetrates the active medium (30). A probe signal (38) to be amplified causes stimulated emission from the excited dye molecules by penetration of its evanescent field into the dye (30) in the region where the cladding is removed.In the preferred embodiment a recirculating pump (110) is used to circulate dye (30) through a cavity (112) placed over the fiber (20) where the cladding portion (70) is removed. The dye molecules in contact with the surface (72) formed by removal of the cladding (66) are continually changed. A temperature control unit (110) maintains the temperature of the dye (30) such that its index of refraction remains tuned to an amount just less than the index of refraction of the core (64).

Abstract: Primary and secondary data save areas are established 
in a volatile memory (CMOS) which is backed up with a 
battery. The same predetermined data are stored in the 
primary and secondary data areas together with check 
sum. At a power on time, the data of the primary area 
are added together and the data of the secondary area 
are added together. When both of results of the addition 
are equal to the check sum, no error is detected. 
When only one of results of addition is different from 
the check sum, an intermittent error is detected. When 
both of results of addition are different from the 
check sum, battery exhausted condition is detected. If 
the intermittent error is detected, data of one area 
whose result of addition is equal to the check sum are 
copied to other area whose result addition is different 
from the check sum.
