Patent EP-0174860-A3 (EP)
Title: Information recording and readout
IPC: G01Q80/00
Filed: 1985-09-12
Abstract: A recording and readout information system having 
atomic scale densities comprises a recording medium hav­
ing a carrier (16) and means (20, 30) to form a pattern of 
atomic paticles (18A) on the surface of the carrier. The atomic 
particles have an affinity for the carrier and can adhere to the 
surface to form a relatively adhesive and stable bond. The 
pattern of atomic particles produced on the carrier are 
representative of recorded information, e.g. binary repre­
sented information, of ultra high density based upon the size 
and spacing of such particles, which is in the range, for 
example, of 5Å (.5 nm) to 10Å (1 nm). A preferred embodi­
ment of the invention comprises a recording medium with an 
adsorbent carrier, and means to form a pattern of adsorbate 
atomic particles on the surface of the adsorbent carrier, the 
adsorbate atomic particles having an adsorptive affinity for 
the adsorbent carrier due - at least in part - to electrical 
attraction characteristics between the adsorbate atomic 
partiles and the adsorbent carrier. Readout means (30), 
utilizing the tunnel current effect, is employed to determine 
the presence or absence of the atomic particles on the 
surface of the carrier and produce an electrical signal 
representative of the pattern of recorded information on the 
recording medium.

Abstract: The invention relates to a process for selectively adsorbing 
ethylbenzene from a stream containing one or more isomeric 
xylenes. The ethylbenzene is adsorbed on an Rb - substituted

Patent EP-0243011-A3 (EP)
Title: Electronic inclination gauge
IPC: G01C9/06
Filed: 1987-03-27
Abstract: An inclination sensor is disclosed which includes a capsule 15 containing a conductive liquid 17 which forms a liquid pendulum and having first and second resistive tracks 11, 13. In a first measuring configuration the terminals A, B of track 11 are connected to positive and negative voltages respectively and the terminals C, D of resistive track 13 are connected together, to form a sensing electrode. The voltage at terminal B is then adjusted so that the voltage at common electrode C, D, sensed through the conductive liquid 17 is adjusted to be zero. The ratio of voltages at terminals A and B is then related to the position of the conductive liquid 17 relative to the resistive track 11 and thus of the inclination of the capsule relative to horizontal. In an alternative measuring configuration, the roles of the resistive tracks 11, 13 are reversed, to allow the sensor to measure angles in a different angular range.
Patent EP-0246032-A3 (EP)
IPC: B05B14/00
Filed: 1987-05-07
Abstract: A spindle 12 and a disc 10 are rotated. Fluid to 
be sprayed is passed through a feeder tube 24 to impinge 
on the conical valve member 30. When the fluid flow rate 
is considerable, the valve member 30 deflects the flow 
outwardly and the fluid then hits the diffuser plate 34 
and is deflected outwardly towards the surface 38 of the 
disc 54. When the fluid hits the disc it is caused to 
move outwardly as a result of the centrifugal force 
exerted by the spinning disc. The fluid then travels 
over the surface 38 until it leaves the periphery 40 of 
the disc and is thrown outwardly.

ment is such that movement of the movable member in the 
axial direction (101) is such that the cooperating tapers cause 
the radially movable member (4) to expand or contract in the 
radial direction (104). Various means for securing and perform­
ing radial movement are disclosed.
