Title: Radiation source for the generation of essentially monochromatic x-rays
IPC: H01J35/02
Filed: 1988-05-11
Abstract: The invention relates to a fluorescence radiation source in which an anode which encloses a member is struck by electrons on its side which faces the member and in which the primary X-ray radiation generated in the anode generates fluorescence radiation in the member. The member is preferably arranged within an enclosing shield which keeps scattered electrons remote from the member.
Patent EP-0274450-A3 (EP)
IPC: G01V3/10
Filed: 1988-01-08
Abstract: A device for measuring the proximity of a metal 
object, and a sensor for such a device are disclosed. 
The device includes a drive and sense coils 220, 230 
which are loosely coupled together. The drive coil is 
driven by a square-wave drive signal, controlled by a 
micro-processor 200. The amplitude of the signal sensed 
by the sense coil 230 in response to the drive signal is 
dependent upon the proximity of a metal object. Sensing 
circuitry 250, 290 is provided for measuring the 
amplitude of this signal to derive a signal indicative 
of the proximity of the metal object. In particular, a 
multiplexor 280 is provided for sampling predetermined 
parts of the signal, (which exhibits a time-dependent 
change when a metal object is proximate). By ignoring 
the initial part of each half cycle of the received 
signal, effects due to conductive but non-metallic 
proximate objects may be ignored. A particular 
application of the device is for sensing the depth of 
reinforcing iron bars in concrete. A novel form of 
sensor (figure 3) is also disclosed.

Patent EP-0354298-A3 (EP)
IPC: G02B27/28
Filed: 1989-04-14
Abstract: An interferometric gas component measurement apparatus has a light source (27), a measurement path (30) which contains the gas components to be measured, a polarizer (11), a double refracting plate arranged with its optical axis at 45 DEG  to the polarization direction, two doubly refracting plates (14, 20) arranged with their optical axes at 45 DEG  to one another and an analyzer (13). The light which passes through the measurement path is concentrated into an output gap (32) and reflected via a holographic concave grid (33) onto a diode row (22). The thickness of the individual plates is so selected that specific linear combinations of the thicknesses result in phase displacements between the beams polarized perpendicular to one another in the plates, with these phase displacements corresponding to the reciprocal of the quasi-periodic line splitting of selected vibration and/or rotation bands of the gas molecules of the gas components to be measured. The output signal of the diode row (22) and the output signal of a rotary position transducer (34) are applied to an electronic evaluation circuit which, at different rotational positions of the rotating plates (14, 20) determines the concentrations (C1, C2, C3) of gases present on the measurement path (30) from the signals received from the diode row (22) (FIG. 1).
Patent EP-0347618-A3 (EP)
Title: Mixing apparatus
IPC: B01F3/04
Filed: 1989-05-30
Abstract: A mixing system for dispersing gas or other 
fluids in liquid which may have a solid suspension so as 
to improve mass transfer to the liquid or its solids 
suspension while maintaining a flow pattern which is 
substantially axial (up and down) in the tank containing 
the liquid thereby also facilitating mixing (blending) 
utilizes an (unshrouded) axial flow impeller which 
provides the desired single stage axial flow downwardly 
to the bottom of the tank and upwardly along the 
sidewalls of the tank with radial flow confined 
principally to the bottom region of the tank. A sparge 
system which releases the gas or other fluid in the 
region at the bottom of the tank where the flow is 
predominantly radial allows attainment of gas rates with 
complete dispersion of gas throughout the tank, which 
rates are much higher (about four times as great) as 
when conventional sparge systems are used with axial 
flow impellers. The gas rate is maximum when the 
impeller has a plurality of blades which are located at 
an elevation of fifteen to twenty-five percent of the 
impeller diameter from the bottom of the tank and the 
outlet ports of the sparge which delivers the gas are 
located at a radius greater than the radius of the 
impeller and at about the same elevation from the bottom 
of the tank as the elevation of the lower edges of the 
impeller's blades. The condition known as flooding 
 
 
where the escaping gas, rather than the impeller, 
controls the flow pattern in the tank (the escaping gas 
then not flowing with the liquid as it is pumped by the 
impeller but rather rising due to its own energy and 
geysering out of the liquid) does not occur, even though 
an axial flow pattern is maintained by an impeller of 
the axial flow type which pumps by virtue of the 
pressure differential across the impeller blades, rather 
than by direct impact with the liquid as in a radial 
flow impeller.

body (10) having a piezoelectric driving section, and a 
second lever body (20) which is disposed to separate 
from and to be perpendicular to the first lever body 
(10), and has a piezoelectric driving section. A

applying circuit (39, 40) alternately applies predeter­
mined voltages to the piezoelectric driving sections of 
the first and second lever bodies (10, 20) to separately 
drive the plurality of probes (12₁ to 12 n ) in different 
directions, thereby three-dimensionally scanning the 
recording medium (22).

Patent EP-0399363-A3 (EP)
IPC: B44C1/10
Filed: 1990-05-16
Abstract: A patterned metallized film (10) comprises a transparent or translucent polymeric film coated on one side with a thin coating of metal, with the metal coating and the polymeric film being bonded to each other. The metal coating has a multiplicity of fractures of different sizes distributed throughout the coating in a prescribed pattern (12) so that the reflection of light by the fractured metal coating produces a three-dimensional illusion of the pattern (12) when viewed through said polymeric film. The film may also include a layer of adhesive on the opposite side of the metal coating from the polymeric film, and a paper backing sheet on the opposite side of the adhesive layer from the metal coating. The fractures are preferably formed by heating the metallized film non-uniformly so that selected areas of the film expand and soften at a rate different from the rate at which other areas of said film expand and soften. The different rates of expansion and softening produce multiple fractures in the metal coating between the selected areas and the other areas, whereby the fractures replicate the desired pattern.

Patent EP-0441090-A3 (EP)
Title: Computer controlled optimized pairing of disk units
IPC: G06F11/20
Filed: 1990-12-28
Abstract: A method of pairing disk units in a computer system where mirroring is desirable is disclosed. Where possible, disk units are paired with other disk units located on a different bus. This provides the highest level of protection against inaccessible data due to data loss or failure of a component in the computer system. Where this is not possible, the remaining disk units are paired with disk units located on a different I/O processor, a different controller, or a different disk enclosure. Where none of these pairings are possible, the remaining disk units fall below the threshold level of protection and therefore cannot be paired within the segment. Any disk units that could not be paired are placed on a spare list. Several attempts are made to pair up disk units on the spare list. If all of these attempts fail, the paired disk units with the lowest level of protection are broken apart and added to the spare list, where attempts are again made to pair up the disk units on the spare list. After all units are paired, a pair of disk units is compared with other pairs of disk units to see if the level of protection can be increased by swapping mates. This comparison of pairs of disk units is repeated until the level of protection is optimized. Each time the computer system is started, a check is made to determine if a configuration change resulted in a lower level of protection. If so, the user is asked if he would like the disk units on the computer system to be re-paired to increase the level of protection. <IMAGE>
