Patent EP-0295053-A3 (EP)
IPC: G03F7/00
Filed: 1988-06-07
Abstract: Three-dimensional photographs produced with image 
bands of substantially equal density across the field of the 
lenticule are produced by increasing the intensity of 
exposure of the image bands near the edges of the lenticule 
in relation to the central image bands. This is 
accomplished by varying the duration of each exposure, or 
using a neutral density filter, a neutral density iris, a 
metallic iris with a multiple number of apertures, or by 
controlling the lamps in a multiple lamp housing. In 
addition, three-dimensional photographs are produced by a 
multiple number of successive exposures of short duration 
through the lenticules of the lenticular print film while 
the angle of projection of the enlarging lens is constantly 
changing. Exposure is made for a duration while the 
relative movement of the enlarging lens with respect to the 
lenticular print film is less than one-tenth of the aperture 
of the enlarging lens.

Title: Monolithic piezoelectric bimorph
IPC: H02N2/04
Filed: 1988-09-15
Abstract: A piezoelectric bimorph is formed by uniformly poling a 
homogeneous sheet of piezoelectric material in a first direction 
and thereafter establishing a substantially linear temperature 
gradient across the sheet while concurrently applying a reverse 
poling field across the sheet of a magnitude selected for 
substantially depoling the middle layers of the sheet, poling the 
hotter layers in the reverse direction and leaving the cooler 
layers poled in the first direction. The impedance of the 
piezoelectric material is monitored to terminate reverse poling 
when the otter and cooler layers are substantially equally 
poled.

Title: Improved electrical switch
IPC: H01H13/02
Filed: 1988-12-07
Abstract: An improved electrical switch providing a 
low electrical-resistance connection and a simple, 
inherent wiping action of the contact surfaces. The

The wadded-wire connector element makes electrical 
contact at multiple points when compressed against a 
contact surface by the switch mechanism, thus wiping 
the contact surfaces free of any film or surface 
contamination and providing a low electrical-resis­
tance connection.

Title: Receiving arrangement with a reception carrier frequency alternately changed from one to another
IPC: H04B7/208
Filed: 1989-05-29
Abstract: In a satellite communication system for carrying 
out communication between a central station and local 
stations, each local station includes a receiving 
apparatus (41) which comprises a converting unit (43) 
for converting a received radio signal of a received 
carrier frequency into a converted signal by using a 
reception carrier signal of a reception carrier 
frequency and a demodulating unit (44) for demodulating 
the converted signal into a demodulated signal. 
Connected to the demodulating unit, a deciding unit (45) 
decides whether the demodulated signal is normal or 
abnormal. The deciding unit produces an abnormal signal 
when the demodulated signal is abnormal. After 
reception of the abnormal signal, a timer circuit (47) 
measures a lapsed time to produce a time up signal when 
the lapsed time is equal to an integral multiple of a 
predetermined time interval. Responsive to the time up 
signal, a supplying section (49) alternately supplies 
first and second carrier signals indicative of first and 
second memorized frequency signal preliminarily 
memorized in a memorizing section (48), respectively, 
one at a time as the reception carrier signal to the 
converting unit.

Abstract: Bei den bisher bekannten Verfahren zur Herstellung von Labkäse aus 
Rohmilch ist der Käsestaub ein echtes Abfallprodukt, da die geklärte 
Molke für die Weiterverarbeitung bestimmt ist.  
     Der Erfindung liegt das Problem zugrunde, das Verfahren zur Her­
stellung von Labkäse aus Rohmilch so zu gestalten, daß der aus der 
Molke anfallende Käsestaub nicht als Abfallprodukt abgetrennt, sondern 
in den Herstellungsprozeß zurückgeführt, der Milch zugemischt oder an­
deren Milchprodukten zwecks Eiweißanreicherung oder Trockenmassener­
höhung zudosiert werden kann.  
     Dieses Problem wird dadurch gelöst, daß der denaturierte Käsestaub 
(Kaseinstaub) so in seine gelöst Form zurückgeführt wird, daß er stabil 
in Lösung bleibt und diese Form bei Vermischung mit Medien, z.B. Milch, 
beibehält.  
     Das Anwendungsgebiet ist die Labkäseherstellung aus Rohmilch.

Title: Set of instruments for intrapleural local anaesthesia
IPC: A61M19/00
Filed: 1989-08-12
Abstract: The kit for intrapleural regional anaesthesia consists of a needle (10) which has at one end a needle connector (11) and at the other end a partly ground central opening (12), of a mandrin which fills the lumen of the needle (10) and of a catheter (30) which can be displaced lengthwise in the needle (10). The needle connector (11) is releasably connected to a Y tube piece (20) which is equipped at the end of its tubular part (21), which is coaxial with the needle (10), with a sealing catheter junction (24, 25, 40) and whose branching-off tubular part (28) is in open connection with a non-deformed collapsible rubber bulb (32). The rubber bulb (32) serves as a detector to indicate that the pleural cavity (15) has been reached, by contraction under the influence of the lower pressure prevailing in the pleural cavity, where the sealing catheter junction (24, 50, 40) on the tubular part (21) which is coaxial with the needle (10) prevents the introduction of outside air into the channel system of the set both when the catheter (30) is inserted and without the catheter. The result of this is that use of the set for pleural analgesia is more straightforward for the user and safer for the patient. <IMAGE>

Title: Canister purge solenoid valve
IPC: F02M25/08
Filed: 1990-05-04
Abstract: The armature (54) contains an elastomeric valve head (58) that is 
biased normally closed against the valve seat (16). When the 
solenoid assembly (20) is energized, the armature is retracted. 
The armature's momentum is initially absorbed by the 
elastomeric valve head making contact with the solenoid 
assembly at one end of the bore. Final absorption of the 
armature's momentum is shared by continuing contact of the 
valve head with the solenoid assembly and by an 
elastomeric limit stop (60) that is disposed between the 
armature and the stator (34). In this way the elastomeric 
limit stop is not required to absorb the full momentum of 
the retracting armature.
