on a single crystal substrate of strontium titanate. 
The ink is dried in an air environment, heated in an 
air environment at a temperature sufficient to 
decompose the neodecanoates, about 500°C, and then 
annealed to promote recrystallization and grain growth 
of the remaining metal oxides. The annealing step 
is preferably accomplished using rapid thermal 
annealing techniques wherein the material is uniformly 
and rapidly heated to an appropriate temperature for an 
amount of time ranging up to about 2 minutes. The 
resulting films of material exhibit superconductive 
characteristics at elevated temperatures above the 
temperature of liquid nitrogen.

Patent EP-0306466-A3 (EP)
IPC: C12M1/36
Filed: 1988-09-01
Abstract: By ensuring that the concentration of dissolved met­
hane (11) and oxygen (13) and ammonium is constant 
throughout the whole of the fermentor (1), a consid­
erable increase is achieved in both the production 
capacity of the biomass as well as its uniformity and 
purity. To this is added a lower production cost, in 
that the cell density in the fluid can be doubled, 
and also a reduction in the consumption of gas.  
     Furthermore, the formation of nitrite can be control­
led with the help of a nitrite meter, thus ensuring 
against the formation of nitrite becoming too great 
and thus hampering the growth.  
     In order to achieve the greatest possible mixing of 
methane and air before its introduction into the 
fermentor, this takes place in one or more ejectors 
(33) which are driven by means of pressure fluid. 
Mechanical mixing arrangements can hereby be avoided.  
     Finally, the supply is effected via nozzles (36), the 
injection direction of which can be adjusted for the 
greatest possible turbulance and therewith the mixing 
in the fermentor.

Title: Filter centrifuge for the separation of suspensions
IPC: B04B3/00
Filed: 1989-05-05
Abstract: Filter centrifuges for the separation of suspensions, the drum of which has a corotating syphon device according to DPS 22 60 461, have the disadvantage that the filtration-accelerating action of the syphon device is destroyed by gas intrusions into the collecting space under the filter medium. Until now, this gas could only be expelled after each charge by backwashing through the filter medium once the solid had been removed. 
<??>The object consists in providing an outlet which permits the expulsion during filtration of gases which have penetrated the syphon space. 
<??>This object is achieved by means of a non-return valve (18) radially arranged within the syphon device, preferably on the drum floor and connected to the collecting space (11) or by an additional syphon device (17, 19, 20, 21) acting as non-return valve. 
<??>This device can be used on discontinuously operating filter centrifuges with rotation syphoning according to DPS 22 60 461, the housing inner space of which is at ambient pressure or is fed with compressed gas for the purpose of further accelerating the filtration.

Title: Weapon training systems
IPC: F41G3/26
Filed: 1989-06-23
Abstract: A weapon simulator, particularly for simulating 
small arms, comprises a laser projector (10) for attachment 
to the weapon (12). Firing the weapon (12) initiates the 
production of a narrow, pulsed, beam (14) by the laser, and 
this beam (14) is scanned vertically downwardly while its PRF 
is varied as a function of scan angle. The 
weapon/ammunition type can also be encoded in the laser 
pulses. The beam (14) is received by a spatially diverse 
pair of detectors on the target, typically comprising a 
first detector having an annular entry aperture covering 
about 6 cm in the vertical direction, and a second 
detector disposed in the centre of the annular entry 
aperture of the first. The central detector 
effectively determines the width of the beam, thus 
permitting the range from the weapon to the target to be 
computed from the beam width and the difference in the 
PRF detected at the start and finish of the illumination 
of the first detector. The elevation angle of the 
weapon with respect to the target is computed from the 
mean PRF detected by the central detector. Finally, 
the accuracy of aim of the weapon (ie whether the firing 
resulted in a hit or a miss) is determined from a 
combination of the range, the weapon elevation angle, 
and the weapon/ammunition type.

Title: Reduced viewport for graphics display
IPC: G06T15/30
Filed: 1989-07-27
Abstract: A reduced viewport feature (80) for a graphics display 
system (18) allows an operator to observe manipulations on 
a graphics display (22) of video image planes (86) that are 
wholly or partially outside a viewing area. A 
two-dimensional input image plane in the forth of a 
wireframe is transformed (60) to a three-dimensional image 
plane due to manipulation, such as rotation and/or 
translation. The resulting three-dimensional image 
plane is subsequently mapped (68) as a two-dimensional 
projection onto the graphics display. Transformation 
matrix coefficients are multiplied (42) by a variable 
reduction coefficient (40) to cause all points of the image 
plane to converge toward the center of the graphics 
display, resulting in the ability to view space which 
originally was not visible to the operator on an 
output video monitor.
