Patent EP-0252365-A3 (EP)
IPC: B01J29/04
Filed: 1987-06-24
Abstract: Aldehydes can be condensed with ketones or 
aldehydes to produce higher aldehydes or ketones by 
contacting the materials to be condensed with a non-­
zeolitic molecular sieve. The condensation may be 
carried out in the presence of hydrogen to give as 
product a saturated aldehyde or ketone. The ketone 
and/or aldehyde may be generated  in situ  by 
dehydrogenation of an alcohol, and the hydrogen thus 
liberated used to effect hydrogenation of the immediate 
unsaturated product of the condensation, thereby 
producing as the final product a saturated aldehyde or 
ketone. The non-zeolitic molecular sieves can achieve 
improved conversion rates and selectivities as compared 
with conventional catalysts for the reaction.

Title: System and circuitry for television signal processing
IPC: H04N11/04
Filed: 1987-12-12
Abstract: This invention permits a coloured TV signal to be efficiently encoded by unidimensional or bidimensional transform, thereby adopting a variable frequency sampling clock and a digital processing of the sampled signal. In this way, one single analog signal can be changed into three signals having statistical characteristics similar to the component signals' (Y,U,V in case of PAL). Encoding through transform of the signals obtained with the system of this invention permits to reach high compression of the information to be transmitted. It is further possible to uniformly treat said composite signals and the component signals by means of practically identical hardware.

Title: So3 flue gas conditioning system
IPC: B03C3/01
Filed: 1987-12-30
Abstract: An air pollution control system for injecting a conditioning agent into the flue gas of a power generator. The conditioning agent changes the resistivity of particulate matter in the flue gas, rendering the particulate matter more easily able to accept an electrostatic charge. Control of the conditioning gas injection rate is monitored by periodically sampling the average input power supplied to the power supplies of the electrostatic flue gas conditioning system. A proportional-integral controller receives the signal representing the difference between the average input power and a predetermined threshold signal. The control signal produced by the proportional integral controller causes incremental changes in the rate at which the conditioning agent, such as SO3, is added to the flue gas.

Title: A cell line producing aids viral antigens without producing infectious virus particles
IPC: C12N5/071
Filed: 1987-04-03
Abstract: Leu-3<-> cells surviving infection with the AIDS retrovirus can be induced with IUdR to express infectious virus. A cellular clone (8E5), isolated by limiting dilution of a mass culture of survivor cells, was found to contain a single, integrated, defective provirus that was constitutively expressed. Although IUdR treatment of 8E5 cells failed to induce infectious virus, cocultivation with Leu-3<+> cells generated the characteristic syncytia associated with acute AIDS retrovirus infection. The single integrated copy of proviral DNA directs the synthesis of all major viral structural proteins except p64 and p34 as monitored by immunoblotting. Diagnostic reagents and kits in accordance with the present invention are also described.

thus enabling correction of that word even if one or two of 
the three sets also contains an error.

eccentrically rotating cylindrical shaft (rotor) is used in a 
cylindrical journal bearing (stator) so arranged that the stator 
can be displaced from the centre of rotation by a known amount. 
Measurements are made of minimum gap between the rotor and stator 
and of the force required to maintain the eccentrically rotating

Patent EP-0298608-A3 (EP)
IPC: H01J49/04
Filed: 1988-06-09
Abstract: A gas chromatography plus mass spectrometry system 
implements a scan strategy in which each full range scan 
alternates between a normal measurement mode and a survey 
mode based on a block/gap map made during the previous 
scan. Survey mode is used within regions that were 
determined in the previous scan to lack signal above a 
predetermined threshold. Spectral data is generated 
during measurement mode operation. Each scan serves both 
measurement and mapping functions in a way that avoids 
mass filter jumps, since each scan is monotonic over the 
entire scanning range.

Filed: 1989-09-27
Abstract: In humid atmospheres (e.g., 55% relative humidity 
or above) solutions of 2,2-bis(3,4-dicarboxyphenyl)hexa­
fluoropropane dianhydride/2,2-bis[4-(aminophenoxy)phenyl]­
hexafluoropropane polyamic acid polymers or polyimides 
tend to be unstable in the sense that during spin coating 
operations undesirable precipitate formation may occur on 
the rotating surface of a semiconductor wafer. The result 
is the formation of unacceptable coatings due to their 
irregularity and lack of uniformity. Described are solu­
tions of these polyamic acid polymers or polyimides in a 
solvent containing at least 40% by weight of one or more 
liquid aromatic hydrocarbons having a boiling point of at 
least about 110°C and at least 5% by weight of one or more 
dipolar aprotic solvents having a boiling point of at 
least about 150°C, such that the solution (a) contains on 
a weight basis from 5% to 40% of the polyamic acid or from 
5% to 50% of the polyimide and (b) does not undergo precip­
itate formation during spin coating in an atmosphere of up 
to at least about 55% relative humidity.

Title: Waveform encoder/decoder
IPC: H03M3/02
Filed: 1989-02-28
Abstract: A waveform encoder/decoder comprising an encoder 
having an input (2) for an audio signal to be encoded, 
and an output (3) whereby the digitally encoded signal 
is passed to a transmission link (not shown) and thence 
to a corresponding decoder (also not shown). The 
encoder comprises detectors (25,26) for monitoring the 
digital output signal for slope overload and idle 
pattern respectively and setting a corresponding value 
in a state machine (27). The value stored in the state 
machine (27) is used to control a pulse width generator 
(28) which in turn controls the enable time of a tri-­
state gate (23) connected in the feedback path from the 
output (3) back to the input. An R.C. filter (22) is 
used to reconstruct the digital output from gate (22) 
to form an estimate of the audio input signal, and this 
estimated signal is compared with the actual input 
signal in a comparator (10). A D-type flip-flop (11) 
is used to digitise the output from comparator (10) to 
generate the signal to be output to the transmission 
link. The circuit, being fully digital, ensures 
improved repeatability and is particularly convenient 
and low in cost.

Title: Thrust-generating device
IPC: F03G3/08
Filed: 1989-07-14
Abstract: An engine is disclosed which comprises a gyroscope means 
taking the form of a rotating bob (340) which is able to 
swing in balanced oscillation about the axis of rotation 
(X) of the plane in which the oscillation takes place 
and thereby generate thrust. The oscillation condition 
of the bob arises from the gyroscopic effects which are 
produced by the plane rotating and this oscillation 
condition in its turn requires the rotating plane to be 
driven by a source of mechanical power (through shaft 
22). By choosing the characteristics of the gyroscope, 
the motion of the bob as the gyroscope is rotated can be 
predetermined and the characteristics may be chosen such 
that the predetermined motion is in a closed movement 
cycle, allowing mechanical or electro-mechanical control.

Filed: 1989-12-20
Abstract: Multicolor printing on the high speed web-fed press 
with cold-set ink increases production efficiency than 
that of on the press with dryers. For this purpose, 
newsprint is used because of its good oil 
absorptiveness, however, the printing quality is not

coated paper for the high speed press was produced. The 
present invention increases the reproducibility of 
dots, sharpness of print pattern comparing to usual 
newsprint without decreasing the handling efficiencies.
