Title: Control method to prevent surge of a centrifugal compressor by means of venting by need
IPC: F04D27/02
Filed: 1989-02-23
Abstract: In the case of known methods of the type stated the normal control is deliberately restricted in its reaction speed. In order to protect the compressor in the event of large and/or sudden malfunctions a safety control is installed which, when it responds by actuating a switch valve, triggers complete rapid opening of the venting valve under spring force. The disadvantage here is that triggering of the safety control leads to a sharp drop in pressure on the pressure side of the compressor. The new method is intended to avoid this drawback. 
<??>The new method is characterised in that a second control differential (x'), where necessary indicating the need for rapid opening of the venting valve, is calculated from the measured values and/or the first control differential (x) and default reference values and fed to a limit value stage and that, if a default limit value in this limit value stage (54) is exceeded by the second control differential (x'), the said stage emits a rapid opening variable (z) on the output side which is sent to the controller (4) where, by cumulative superimposition, a change in the valve control variable (y) is produced with an increased rate of change causing actuation of the valve in the opening direction. The new method has the advantage that, where necessary, it increases the reaction speed of the control so that in the event of major and/or rapid malfunctions a prompt opening of the venting valve is ensured which furthermore takes place only as far and as prolonged as necessary. 
<??>The new method is suitable for the control of turbocompressors in any sphere of application, in particular for retrofitting to existing controls.

IPC: G03C7/30
Filed: 1989-10-03
Abstract: A method for forming an image, which comprises 
developing a silver halide color photographic material 
with a color developer containing at least one aromatic 
primary amine color developing agent, wherein said silver 
halide color photographic material comprises a silver 
chloride or silver chlorobromide emulsion having an 
average silver bromide content of not more than 10 mol% 
and containing substantially no iodide, with a mean grain 
size of an emulsion contained in the blue-sensitive layer 
thereof being controlled to 0.9 µm or smaller, silver 
halide to coupler ratio in said blue-sensitive layer 
ranges from 2 to 5 as a molar ratio, and said color 
developer contains from 3.5 x 10⁻² to 1.5 x 10⁻¹ mol/ℓ of 
a chloride ion and from 3.0 x 10⁻⁵ to 1.0 x 10⁻³ mol/ℓ of 
a bromide ion. The method achieves rapid processing to 
provide an image having high maximum density and low 
density without causing streaky pressure marks even when 
processing is carried out with an automatic developing 
machine or without a variation of photographic 
characteristics, particularly gradation in low density 
areas, occurring even when processing is carried out 
continuously.

Title: Child-resistant closure device
IPC: B65D41/04
Filed: 1989-06-29
Abstract: A safety closure device for a closeable 
container is provided which, at the user's option, can be 
operated in a child-resistant mode of operation or, by a 
simple one-time action by the user, can be placed in a 
non-child-resistant mode of operation. An outer cap (22) 
rotatably and slidingly engages an inner cap (26) that directly 
closes a container, with an intermediate element (24) biasing 
the outer and inner caps apart from each other but formed 
so as to take up a first position in which an axially 
applied force by the user temporarily non-rotatably 
couples the inner and outer caps for child-resistant 
operation, and an axially applied force on the 
intermediate element coupled with a partial turning of the 
outer cap relative thereto causes permanent non-rotatable 
engagement between the outer and inner caps through the 
intermediate element to make the safety closure non-child-­
resistant.

Title: Identification means with encrypted security code
IPC: G07F7/12
Filed: 1989-10-05
Abstract: An identification code has both general information which is 
encrypted using standards symbologies and security 
information which is encrypted using a unique symbology. In 
the case of bar codes, the bar code may include two separate 
sets of bars. One set of bars may include basic 
information, for example an employee's identification 
number, encrypted using standard symbologies which may be 
read in any standard reader. The other set of bars includes 
security information which is encrypted using a unique 
symbology which can be read only in a special reader and 
which is meaningless to a standard bar code reader or bar 
code duplicator. Thus, where security is a factor, the 
special readers would be provided; but, where security is 
not a factor, the basic identification could be read by any 
standard reader.

Title: Electronic device manufacture involving a pattern delineation step
IPC: H01L21/302
Filed: 1990-04-09
Abstract: Fine featured devices are produced by a series of fabrication steps including 
exposing selective surface regions to irradiation, e.g. to an ion beam, generally to 
result in removal of masking material within irradiated regions. In most instances, 
subsequent etching is under conditions such that bared material is preferentially 
removed. Etch-removal and irradiation are such that overgrown material is of device 
quality at least in etched regions. The inventive process is of particular value in the 
fabrication of integrated circuits, e.g. circuits performing electronic and/or optical 
functions. The inventive process is expediently used in the fabrication of structures 
having minimum feature size of 1 micrometer and smaller. Patterning is dependent 
upon masking material of a maximum thickness of 100Å.

Title: A method for interfacing a system of supercritical fluid extraction (sfe) to a system of capillary gas chromatography (cgc), and related interface
IPC: G01N30/30
Filed: 1990-05-18
Abstract: The coupling between a system of supercritical fluid 
extraction (SFE) (14)  and a gas chromatographic analytical 
system with capillary columns (CGC) (40) is obtained by 
separating the decompression stage (38) of the extraction fluid 
from the sampling system (44) and from the system of gas 
chromatographic separation (40).  
     The high pressure supercritical fluid is expanded outside 
of the gas chromatographic system (40), with a heated 
environment (38), and then it is carried a certain length, 
always under heating, before being fed to the 
chromatographic system (40).  
     The gas flows through a cold trap (44) for reconcentration 
which entraps the components of the sample to be analysed 
eliminating the extraction fluid. The introduction of the 
entrapped compounds into the chromatographic column is 
then carried out by means of a process of thermal 
desorption.
