Fire lighters (F) are highly inflammable, e.g. solidified alcohol, and sufficient fuel (H), e.g. timber charcoal, is provided to complete the cooking process, both materials being contained in sealed bags. The choice of thin gauge metal for the crucible ensures that mfg. costs are low.
Patent FR-2245929-A1 (FR)
Title: Displacement measuring digital instrument - has sensor and numerical display to increase accuracy
IPC: B23Q17/24
Filed: 1973-09-14
Abstract: The displacement measuring digital instrument has a linear or angular sensor (2) which detects displacement and supplies a phase difference as output signal. There is a clock (1) which supplies pulses to the sensor (2) and to a phase modulator (5), and a comparator (4) which receives the signals from the sensor (2) and the modulator (5). The output signals of the comparator (4) control the action of the clock pulses on the phase modulator (5) so as to null out the phase difference detected by the comparator. The clock pulses applied to the comparator (5) are counted by a counter (9) which indicates the total number of pulses. The numerical display of the counter (9) is then proportional to the lead or lag detected by the sensor (2).

Title: Barbituric acid-papaverine salts - for treatment of cardiovascular disorders, free from the drawbacks of papaverine base
IPC: C07D251/34
Filed: 1973-11-12
Abstract: Cpds. of formula (I) (where R = alkyl, pref. 1-6C, or phenyl, and the nitrogen atom of the barbituric acid may also be substituted), which are prepd. by combining one mole of barbituric acid (which may be mono-substd. or the ethylene gp.) with one mole of papaverine base, are used in medicaments for the treatment of cardiovascular disorders, since they have spasmolytic, hypotensive antiarrhythmic and coronary dilating properties. (I) have a spasmolytic action which is greater than the papaverine and barbituric acid starting materials, a reduced hypnotic effect, and an increased coronary dilating effect. (I) may be used for conditions in which papaverine itself can not be used.

Filed: 1974-06-10
Abstract: A printing plate is produced by exposing imagewise to a coherent radiation of continuous wave length 4400-8000 angstroms, i.e. a laser beam, the surface of an optical mask comprising an opaque layer of a material which absorbs the coherent radiation but reflects UV rays in the range 2000-4000 angstroms, the layer being superposed on a substrate which transmits both the coherent and UV radiations, (2) modulating and scanning the coherent radiation to selectively eliminate zones in the layer and reveal the underlying substrate, (3) placing the optical mask over a photosensitive compn. applied onto a second substrate, (4) exposing the photo. compn. to a non-coherent UV radiation of wave length 2000-4000 angstroms to insolubilise the exposed parts of the compn. and (5) removing the unexposed zones of the compn. Use of a laser beam gives instantaneous image formation through perforation of millions of holes in the opaque layer without recourse to subsequent physical or chemical development and enables long distance reproductions of prints from e.g. newspapers and magazines to be effected within seconds c.f. ca 4 minutes in conventional photographic processes.

Title: Detoxification of hydrogen cyanide and nitrous gases - by gas phase reaction, opt at high temp and or over catalyst
IPC: C01B32/50
Filed: 1975-07-16
Abstract: The detoxification of gaseous HCl and nitrous gases is achieved by reacting these in the gas phase, pref. at 25-1400 degrees C and opt. in the presence of a catalyst, pref, a Pt gp. metal or an oxide of Fe, Ni, Cu, Cr and/or Bi and pref. in the absence of O2. Any excess nitrous gases present after reaction can be reduced to N2 in a reducing flame. NO, NO2 and N2O4 react with HCN, giving CO2 and N2, even at low temps., although the reaction is accelerated by the use of a higher temp. and/or a catalyst. The process is useful for the detoxification of solids contg. cyanides and nitrites, esp. hardening salts, which are treated with acid to liberate the toxic gases.

Title: Radioactive isotopes of molybdenum and xenon prepn. - from fission prods. of uranium 235 and their sepn. from contaminants
IPC: G21G1/08
Filed: 1976-01-28
Abstract: 99Mo and 133Xe are made by irradiating a target contg. a fissile substance esp. 235V and dissolving it in a basic medium extracting 99Mo from the soln. obtd. and recovering 133Xe from the gas phase produced by the dissolution. The soln. is filtered and the filtrate acidified to remove the 99Mo by extraction chromatography. Process avoids the problems associated with the replace of hydrogen during dissoln. as occurred in prior art when 8M NaOH was used as basic medium followed by liquid-liquid extraction. The 99Mo and the 133Xe are prepd. from the same irradiated target. Since the soln. contains no contaminating V, the shielding can be less stringent than in prior art.
