Patent EP-0270862-A3 (EP)
IPC: H01S3/139
Filed: 1987-11-10
Abstract: The invention in exemplary, differential absorption 
laser (DIAL) application, entails determining the 
number density "N" in an atmosphere column of a 
constituent whose absorbance is indicative of the value 
of "N", by use of first of the relationship:- 
  to establish an 
assumed correct value for "N" (a first value for (σ OFF 
- σ ON) being obtained from known data) at arbitrarily 
chosen "OFF" and "ON" frequencies, thereafter using 
that value of "N" to determine further values of (σ OFF 
- σ ON) at further "OFF" and "ON" frequencies until a 
value therefor is detained which is constant or near 
constant, and then, using that value, re-calculating 
"N" by the further relationship:-  
2N(σ OFF -σON) x Z = 1.1 >  
where Z is the range, and  
σ OFF and σ ON = the absorbance cross-section for one 
molecule of the constituent in the column at the 
respective "OFF" and "ON" frequencies. The technique 
is also employed to effect a range cell determination 
as such to effect a range intervening column using 
appropriate further relationships. It may also be used 
to determine a parameter other than "N".

tetrahydrofuran and n is 2 which is prepared by 
   (a) providing an adduct of the complex M(hfa)₂ 
which comprises one or more adducted water 
molecules;    (b) dissolving the water-containing adduct in 
excess THF to form a reaction mixture wherein 
the adduct will react with the THF to replace 
the adducted molecules by THF;    (c) evaporating the reaction mixture to dryness to 
form a solid residue; and    (d) collecting the M(hfa)₂.nTHF product from the 
residue by sublimation of the residue.

Patent EP-0256840-A3 (EP)
IPC: B01J41/20
Filed: 1987-08-11
Abstract: A process for continuously separating acids from a mixture of 
acids and their corresponding salts employing the concept 
of acid retardation is disclosed. The process is carried out by 
feeding the mixture to an Advanced Separation Device filled 
with a resin which preferentially adsorbs the acid over the 
corresponding salt. By virtue of the preferential adsorption of 
the acid by the resin, the addition of an eluant such as water causes 
the salt to elute first and the acid second. The 
Advanced Separation Device enables the process to be carried out 
continuously and is amenable to the low relative treatment 
ratios necessary for exploitation of the acid retardation 
concept.

Abstract: In an internal combustion engine (20) the centre 
line (26) of each cylinder (22) is offset from the

timing provides earlier effective torque during the 
power stroke, inherent suppression of premature 
detonation or knocking, increased volumetric and 
mechanical efficiency, lower thrust loading on the 
cylinder walls, and decreased vibration.

crimping, that will be contacted by the solder when the 
connection is formed and which increases the force 
required to pull the two conductors apart.

Title: Zero power, electrically alterable, nonvolatile latch
IPC: H03K3/356
Filed: 1989-01-21
Abstract: A compact, nonvolatile, zero static power, electrically alterable, 
bistable CMOS latch device is fabricated with single layer of 
polysilicon. The single polysilicon layer forms the floating gates of 
the nonvolatile elements of the device. The control gates are formed in 
the substrate by burried N+ diffusions and are separated from their 
respective floating gates by a thin oxide dielectric. The circuit can be 
designed to power-up in a preferred mode even before any programming 
operation has been performed on it. Thereafter, the circuit is available 
to be programmed to either of its two stable states. After the 
programming operation is completed and the circuit is latched to one of 
its two stable states, the fields across the thin oxide dielectrics are 
minimal and virtually no read disturb condition exist. Thus, the latch 
also offers excellent data retention characteristics.
Patent EP-0336173-A3 (EP)
IPC: H01L23/31
Filed: 1989-03-17
Abstract: A molded package (32) for an electrical or electronic component 
subject to voltage surges includes a metallic substrate (28, 29) 
isolated to withstand the potential of the voltage surges. The 
isolation is provided by locating breakoff points (31) for the 
supports of the substrate (28, 29) prior to the molding operation 
within the interior most portions of recesses (36, 37) in the molded 
package. This technique therefore provides a long arc path from the 
exposed breakoff to proximate points of potential difference due to 
the occurence of the voltage surges.
